Gynaecological cancers are a group of different malignancies of the female reproductive system. The most common types of gynaecologic malignancies are cervical cancer, ovarian cancer, and endometrial (uterus) cancer. There are other less common gynaecological malignancies including cancer of the vagina, cancer of the vulva, gestational trophoblastic tumours, and fallopian tube cancer. Occasionally skin cancers or sarcomas can also be found in the female genitalia. Generally, most gynaecological cancers are found in women aged over 50, though the incidence rates for younger women have been rising.

Female Hormonal Factors and the Risk of Endometrial Cancer in Lynch Syndrome.
JAMA. 2015; 314(1):61-71 [PubMed] Related Publications
OBJECTIVE: To investigate the association between hormonal factors and endometrial cancer risk in Lynch syndrome.
DESIGN, SETTING, AND PARTICIPANTS: A retrospective cohort study included 1128 women with a mismatch repair gene mutation identified from the Colon Cancer Family Registry. Data were analyzed with a weighted cohort approach. Participants were recruited between 1997 and 2012 from centers across the United States, Australia, Canada, and New Zealand.
EXPOSURES: Age at menarche, first and last live birth, and menopause; number of live births; hormonal contraceptive use; and postmenopausal hormone use.
MAIN OUTCOMES AND MEASURES: Self-reported diagnosis of endometrial cancer.
RESULTS: Endometrial cancer was diagnosed in 133 women (incidence rate per 100 person-years, 0.29; 95% CI, 0.24 to 0.34). Endometrial cancer was diagnosed in 11% (n = 70) of women with age at menarche greater than or equal to 13 years compared with 12.6% (n = 57) of women with age at menarche less than 13 years (incidence rate per 100 person-years, 0.27 vs 0.31; rate difference, -0.04 [95% CI, -0.15 to 0.05]; hazard ratio per year, 0.85 [95% CI, 0.73 to 0.99]; P = .04). Endometrial cancer was diagnosed in 10.8% (n = 88) of parous women compared with 14.4% (n = 40) of nulliparous women (incidence rate per 100 person-years, 0.25 vs 0.43; rate difference, -0.18 [95% CI, -0.32 to -0.04]; hazard ratio, 0.21 [95% CI, 0.10 to 0.42]; P < .001). Endometrial cancer was diagnosed in 8.7% (n = 70) of women who used hormonal contraceptives greater than or equal to 1 year compared with 19.2% (n = 57) of women who used contraceptives less than 1 year (incidence rate per 100 person-years, 0.22 vs 0.45; rate difference, -0.23 [95% CI, -0.36 to -0.11]; hazard ratio, 0.39 [95% CI, 0.23 to 0.64]; P < .001). There was no statistically significant association between endometrial cancer and age at first and last live birth, age at menopause, and postmenopausal hormone use.
CONCLUSIONS AND RELEVANCE: For women with a mismatch repair gene mutation, some endogenous and exogenous hormonal factors were associated with a lower risk of endometrial cancer. These directions and strengths of associations were similar to those for the general population. If replicated, these findings suggest that women with a mismatch repair gene mutation may be counseled like the general population in regard to hormonal influences on endometrial cancer risk.
Imprinted Genes on Chromosome 6 Are Unlikely to Cause Hydatidiform Mole. A Report of Two Cases.
J Reprod Med. 2015 May-Jun; 60(5-6):261-4 [PubMed] Related Publications
CASES: We studied two rare cases of triploid, diandric moles that were tetrasomic for chromosome 6. DNA-marker analysis showed that in one mole the fourth chromosome 6 originated in the father, and in the other mole the fourth chromosome 6 originated in the mother. Histopathologic revision disclosed that both moles were partial moles with no significant difference in the phenotypes.
CONCLUSION: It is unlikely that a major gene involved in the pathogenesis of hydatidiform mole, or a major gene involved in determining the severity of the molar phenotype, is located on chromosome 6.
Sclerosing Stromal Ovarian Tumor Combined with Early Onset Severe Preeclampsia. A Case Report.
J Reprod Med. 2015 May-Jun; 60(5-6):249-53 [PubMed] Related Publications
CASE: We report a case of SST of the ovary combined with early onset severe preeclampsia.
CONCLUSION: We document the clinical and pathological characteristics of the patient's disease, including the effects on the pregnancy and fetus.
Reproductive Outcomes in Women Following Radiofrequency Volumetric Thermal Ablation of Symptomatic Fibroids. A Retrospective Case Series Analysis.
J Reprod Med. 2015 May-Jun; 60(5-6):194-8 [PubMed] Related Publications
STUDY DESIGN: Retrospective analysis of fibroid characteristics, treatment parameters, and pregnancy outcomes of 6 subjects in 3 prospective trials of laparoscopic ultrasound-guided RFVTA.
RESULTS: Despite the requirement that women enrolled in the RFVTA studies did not desire current or future childbearing and were to continue contraception, 6 subjects conceived at between 3.5 and 15 months postreatment. The number of fibroids treated per patient ranged from 1 to 7, measured between 1.0 cm and 7.6 cm at the greatest diameter, and included multiple types (submucosal, intramural, transmural, and subserosal). Five patients (5/6, 83%) delivered full-term healthy infants: 1 by vaginal delivery and 4 by cesarean section. One patient (1/6, 17%) had a spontaneous miscarriage in the first trimester.
CONCLUSION: Viable, full-term pregnancies are possible after RFVTA. Further, in-depth study of pregnancy outcomes following laparoscopic ultrasound-guided radiofrequency, volumetric ablation of fibroids is warranted.
Involved LEEP excision margins as predictor of residual/recurrent disease in HIV-positive and HIV-negative women in a low-resource setting.
Anal Quant Cytopathol Histpathol. 2015; 37(2):105-8 [PubMed] Related Publications
STUDY DESIGN: Cross-sectional study of 176 LEEPs indicated for a cytological report of high-grade squamous intraepithelial lesion (HGSIL). A total of 72 HIV-positive and 104 HIV-negative women with cervical intraepithelial neoplasia (CIN) ≥ 2 on their LEEP histology report with involved excision margins were enrolled in the study. All patients underwent either a repeat LEEP or a hysterectomy. The specimens were evaluated for residual/recurrent CIN ≥ 2 or less.
RESULTS: Persistent/recurrent CIN ≥ 2 was diagnosed in 139 (79.4%) instances and microinvasive squamous cell carcinoma in 6 (3.4%). Thirty (17.2%) showed CIN1. The persistence/recurrence rate was 72.2% and 88.5% in HIV-positive and HIV-negative women, respectively (χ2 = 7.5, p = 0.006).
CONCLUSION: In > 80% the diagnosis of involved excision margins was confirmed, a positive predictive value of 82.4%. In the absence of more accurate follow-up methods such as HPV testing or co-testing with cytology, a correct diagnosis of margin status, especially when involved, is an important guide to further management and follow-up.

The vaccine and cervical cancer screen (VACCS) project: acceptance of human papillomavirus vaccination in a school-based programme in two provinces of South Africa.
S Afr Med J. 2015; 105(1):40-3 [PubMed] Related Publications
OBJECTIVES: To investigate acceptance of school-based human papillomavirus (HPV) vaccination, as well as the information provided, methods of obtaining consent and assent, and completion rates achieved.
METHODS: Information on cervical cancer and HPV vaccination was provided to 19 primary schools in Western Cape and Gauteng provinces participating in the study. Girls with parental consent and child assent were vaccinated during school hours at their schools.
RESULTS: A total of 3 465 girls were invited to receive HPV vaccine, of whom 2 046 provided written parental consent as well as child assent. At least one dose of vaccine was delivered to 2 030 girls (99.2% of the consented cohort), while a total of 1 782 girls received all three doses. Sufficient vaccination was achieved in 91.6% of the vaccinated cohort. Of all invited girls, 56.9% in Gauteng and 50.7% in the Western Cape were sufficiently vaccinated.
CONCLUSION: This implementation project demonstrated that HPV vaccination is practical and safe in SA schools. Political and community acceptance was good, and positive attitudes towards vaccination were encountered. During the study, which mimicked a governmental vaccine roll-out programme, high completion rates were achieved in spite of several challenges encountered.

Does neoadjuvant chemotherapy plus cytoreductive surgery improve survival rates in patients with advanced epithelial ovarian cancer compared with cytoreductive surgery alone?
J BUON. 2015 Mar-Apr; 20(2):580-7 [PubMed] Related Publications
METHODS: A total of 292 patients with stages IIIC and IV disease who were treated with either NAC/IDS or PDS between 1995 and 2012 were retrospectively reviewed. The study population was divided into two groups: the NAC/IDS group (N=84) and the PDS group (N=208). Progression-free survival (PFS), overall survival (OS), and optimal cytoreduction were compared.
RESULTS: The mean age was significantly higher in the NAC/IDS group (61.5±11.5 vs 57.8±11.1 years, p=0.01). Optimal cytoreduction was achieved in 34.5% (29/84) of the patients in the NAC/IDS group and in 32.2% (69/208) in the PDS group (p=0.825). The survival rates were comparable. The mean survival rate of patients who achieved optimal cytoreductive surgery in either the PDS or the NAC/IDS arm was significantly higher than that of patients who achieved suboptimal cytoreductive surgery (p<0.001 and p<0.001, respectively). Multivariate analysis confirmed the treatment method, amount of ascitic fluid, and optimal cytoreduction as independent factors for OS.
CONCLUSIONS: No definitive evidence was noticed regarding whether NAC/IDS increases survival compared with PDS. NAC should be reserved for patients who cannot tolerate PDS or when optimal cytoreduction is not feasible.
Mediterranean diet and risk of endometrial cancer: a pooled analysis of three Italian case-control studies.
Br J Cancer. 2015; 112(11):1816-21 [PubMed] Related Publications
METHODS: We analysed this issue pooling data from three case-control studies carried out between 1983 and 2006 in various Italian areas and in the Swiss Canton of Vaud. Cases were 1411 women with incident, histologically confirmed endometrial cancer, and controls were 3668 patients in hospital for acute diseases. We measured the adherence to the Mediterranean diet using a Mediterranean Diet Score (MDS), based on the nine dietary components characteristics of this diet, that is, high intake of vegetables, fruits/nuts, cereals, legumes, fish; low intake of dairy products and meat; high monounsaturated to saturated fatty acid ratio; and moderate alcohol intake. We estimated the odds ratios (OR) and the corresponding 95% confidence intervals (CI) for increasing levels of the MDS (varying from 0, no adherence, to 9, maximum adherence) using multiple logistic regression models, adjusted for major confounding factors.
RESULTS: The adjusted OR for a 6-9 components of the MDS (high adherence) compared with 0-3 (low adherence) was 0.43 (95% CI 0.34-0.56). The OR for an increment of one component of MDS diet was 0.84 (95% CI 0.80-0.88). The association was consistent in strata of various covariates, although somewhat stronger in older women, in never oral contraceptive users and in hormone-replacement therapy users.
CONCLUSIONS: Our study provides evidence for a beneficial role of the Mediterranean diet on endometrial cancer risk, suggesting a favourable effect of a combination of foods rich in antioxidants, fibres, phytochemicals, and unsaturated fatty acids.
Bladder cancer incidence and mortality in patients treated with radiation for uterine cancer.
BJU Int. 2014; 114(6):844-51 [PubMed] Related Publications
PATIENTS AND METHODS: In this retrospective cohort study, records of 56 681 patients diagnosed with UtC as their first primary malignancy during 1980-2005 were obtained from the Surveillance, Epidemiology and End-Results (SEER) database. Follow-up for incident BC ended on 31 December 2008. Occurrences of BC diagnoses and BC deaths in patients with UtC managed with or without RT were summarised with counts and person-time incidence rates (counts divided by person-years of observation). Age adjustment of rates was performed by direct standardisation. Incident BC cases were described in terms of histological types, grades and stages.
RESULTS: With a mean follow-up of 15 years, BC was diagnosed in 146 (0.93%) of 15 726 patients with UtC managed with RT, and in 197 (0.48%) of 40 955 patients with UtC managed without RT, with an age-adjusted rate ratio of 2.0 (95% confidence interval [CI] 1.6-2.5). Fatal BC occurred in 39 (0.25%) and 36 (0.09%) of patients with UtC managed with vs without RT, respectively, with an age-adjusted rate ratio of 2.9 (95% CI 1.8-4.6). Incident BC cases diagnosed in patients with UtC managed with vs without RT had similar distributions of histological types, grades, and stages.
CONCLUSIONS: Use of RT for UtC is associated with increased BC incidence and mortality later in life. Heightened awareness should help identify women with new voiding symptoms or haematuria, all of which should be fully evaluated.
Primary chemotherapy versus primary surgery for newly diagnosed advanced ovarian cancer (CHORUS): an open-label, randomised, controlled, non-inferiority trial.
Lancet. 2015; 386(9990):249-57 [PubMed] Related Publications
METHODS: In this phase 3, non-inferiority, randomised, controlled trial (CHORUS) undertaken in 87 hospitals in the UK and New Zealand, we enrolled women with suspected stage III or IV ovarian cancer. We randomly assigned women (1:1) either to undergo primary surgery followed by six cycles of chemotherapy, or to three cycles of primary chemotherapy, then surgery, followed by three more cycles of completion chemotherapy. Each 3-week cycle consisted of carboplatin AUC5 or AUC6 plus paclitaxel 175 mg/m(2), or an alternative carboplatin combination regimen, or carboplatin monotherapy. We did the random assignment by use of a minimisation method with a random element, and stratified participants according to the randomising centre, largest radiological tumour size, clinical stage, and prespecified chemotherapy regimen. Patients and investigators were not masked to group assignment. The primary outcome measure was overall survival. Primary analyses were done in the intention-to-treat population. To establish non-inferiority, the upper bound of a one-sided 90% CI for the hazard ratio (HR) had to be less than 1.18. This trial is registered, number ISRCTN74802813, and is closed to new participants.
FINDINGS: Between March 1, 2004, and Aug 30, 2010, we randomly assigned 552 women to treatment. Of the 550 women who were eligible, 276 were assigned to primary surgery and 274 to primary chemotherapy. All were included in the intention-to-treat analysis; 251 assigned to primary surgery and 253 to primary chemotherapy were included in the per-protocol analysis. As of May 31, 2014, 451 deaths had occurred: 231 in the primary-surgery group versus 220 in the primary-chemotherapy group. Median overall survival was 22.6 months in the primary-surgery group versus 24.1 months in primary chemotherapy. The HR for death was 0.87 in favour of primary chemotherapy, with the upper bound of the one-sided 90% CI 0.98 (95% CI 0.72-1.05). Grade 3 or 4 postoperative adverse events and deaths within 28 days after surgery were more common in the primary-surgery group than in the primary-chemotherapy group (60 [24%] of 252 women vs 30 [14%] of 209, p=0.0007, and 14 women [6%] vs 1 woman [<1%], p=0.001). The most common grade 3 or 4 postoperative adverse event was haemorrhage in both groups (8 women [3%] in the primary-surgery group vs 14 [6%] in the primary-chemotherapy group). 110 (49%) of 225 women receiving primary surgery and 102 (40%) of 253 receiving primary chemotherapy had a grade 3 or 4 chemotherapy related toxic effect (p=0.0654), mostly uncomplicated neutropenia (20% and 16%, respectively). One fatal toxic effect, neutropenic sepsis, occurred in the primary-chemotherapy group.
INTERPRETATION: In women with stage III or IV ovarian cancer, survival with primary chemotherapy is non-inferior to primary surgery. In this study population, giving primary chemotherapy before surgery is an acceptable standard of care for women with advanced ovarian cancer.

The management of uterine fibroids in women with otherwise unexplained infertility.
J Obstet Gynaecol Can. 2015; 37(3):277-88 [PubMed] Related Publications
OPTIONS: Management of fibroids in women wishing to conceive first involves documentation of the presence of the fibroid and determination of likelihood of the fibroid impacting on the ability to conceive. Treatment of fibroids in this instance is primarily surgical, but must be weighed against the evidence of surgical management improving clinical outcomes, and risks specific to surgical management and approach.
OUTCOMES: The outcomes of primary concern are the improvement in pregnancy rates and outcomes with management of fibroids in women with infertility.
EVIDENCE: Published literature was retrieved through searches of PubMed, MEDLINE, the Cochrane Library in November 2013 using appropriate controlled vocabulary (e.g., leiomyoma, infertility, uterine artery embolization, fertilization in vitro) and key words (e.g., fibroid, myomectomy). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English and French. There were no date restrictions. Searches were updated on a regular basis and incorporated in the guideline to November 2013. Grey (unpublished literature) was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies.
VALUES: The quality of evidence in this document was rated using the criteria described by the Canadian Task Force on Preventive Health Care (Table).
BENEFITS, HARMS, AND COSTS: These recommendations are expected to allow adequate management of women with fibroids and infertility, maximizing their chances of pregnancy by minimizing risks introduced by unnecessary myomectomies. Reducing complications and eliminating unnecessary interventions are also expected to decrease costs to the health care system. Summary Statements 1. Subserosal fibroids do not appear to have an impact on fertility; the effect of intramural fibroids remains unclear. If intramural fibroids do have an impact on fertility, it appears to be small and to be even less significant when the endometrium is not involved. (II-3) 2. Because current medical therapy for fibroids is associated with suppression of ovulation, reduction of estrogen production, or disruption of the target action of estrogen or progesterone at the receptor level, and it has the potential to interfere in endometrial development and implantation, there is no role for medical therapy as a stand-alone treatment for fibroids in the infertile population. (III) 3. Preoperative assessment of submucosal fibroids is essential to the decision on the best approach for treatment. (III) 4. There is little evidence on the use of Foley catheters, estrogen, or intrauterine devices for the prevention of intrauterine adhesions following hysteroscopic myomectomy. (II-3) 5. In the infertile population, cumulative pregnancy rates by the laparoscopic and the minilaparotomy approaches are similar, but the laparoscopic approach is associated with a quicker recovery, less postoperative pain, and less febrile morbidity. (II-2) 6. There are lower pregnancy rates, higher miscarriage rates, and more adverse pregnancy outcomes following uterine artery embolization than after myomectomy. (II-3) Studies also suggest that uterine artery embolization is associated with loss of ovarian reserve, especially in older patients. (III) Recommendations 1. In women with infertility, an effort should be made to adequately evaluate and classify fibroids, particularly those impinging on the endometrial cavity, using transvaginal ultrasound, hysteroscopy, hysterosonography, or magnetic resonance imaging. (III-A) 2. Preoperative assessment of submucosal fibroids should include, in addition to an assessment of fibroid size and location within the uterine cavity, evaluation of the degree of invasion of the cavity and thickness of residual myometrium to the serosa. A combination of hysteroscopy and transvaginal ultrasound or hysterosonography are the modalities of choice. (III-B) 3. Submucosal fibroids are managed hysteroscopically. The fibroid size should be < 5 cm, although larger fibroids have been managed hysteroscopically, but repeat procedures are often necessary. (III-B) 4. A hysterosalpingogram is not an appropriate exam to evaluate and classify fibroids. (III-D) 5. In women with otherwise unexplained infertility, submucosal fibroids should be removed in order to improve conception and pregnancy rates. (II-2A) 6. Removal of subserosal fibroids is not recommended. (III-D) 7. There is fair evidence to recommend against myomectomy in women with intramural fibroids (hysteroscopically confirmed intact endometrium) and otherwise unexplained infertility, regardless of their size. (II-2D) If the patient has no other options, the benefits of myomectomy should be weighed against the risks, and management of intramural fibroids should be individualized. (III-C) 8. If fibroids are removed abdominally, efforts should be made to use an anterior uterine incision to minimize the formation of postoperative adhesions. (II-2A) 9. Widespread use of the laparoscopic approach to myomectomy may be limited by the technical difficulty of this procedure. Patient selection should be individualized based on the number, size, and location of uterine fibroids and the skill of the surgeon. (III-A) 10. Women, fertile or infertile, seeking future pregnancy should not generally be offered uterine artery embolization as a treatment option for uterine fibroids. (II-3E).
Performance measures related to colposcopy for canadian cervical cancer screening programs: identifying areas for improvement.
J Obstet Gynaecol Can. 2015; 37(3):245-51 [PubMed] Related Publications
METHODS: As part of a national report on the performance of cervical cancer screening, aggregate provincial cervical cancer screening data provided by provinces to the Pan-Canadian Cervical Screening Network were used to evaluate colposcopy program performance measures for women 20 to 69 years of age who had a Pap test in 2009 and 2010.
RESULTS: A total of 37 523 women had a high-grade or more severe Pap test result. The proportion of women who had a colposcopy ≤ 90 days after their Pap test ranged from 30.9% to 51.5%. Fewer women 60 to 69 years of age had a colposcopy than women in younger age groups. The proportion of women who had a high-grade or more severe Pap test result and colposcopy who had a biopsy within 12 months ranged from 82.1% to 96.5%. The proportion of biopsy results that agreed with the Pap test result ranged from 59.5% to 82.1%.
CONCLUSION: The time from having a high-grade Pap test result to undergoing colposcopy must be reduced to lower the risk of adverse outcomes and the stress associated with delayed follow-up. The agreement between screening cytology and histology meets the national target of ≥ 65%. Although six of 13 provinces and territories provided data for colposcopy-related performance measures, more information is needed to assess colposcopy services accurately at the national level.
MR Spectroscopy for Differentiating Benign From Malignant Solid Adnexal Tumors.
AJR Am J Roentgenol. 2015; 204(6):W724-30 [PubMed] Related Publications
MATERIALS AND METHODS: Sixty-nine patients with surgically and histologically proven solid adnexal tumors (27 benign and 42 malignant) underwent conventional MRI and (1)H-MRS. Single-voxel spectroscopy was performed using the point-resolved spectroscopy localization technique with a voxel size of 2 × 2 × 2 cm(3). Resonance peak integrals of choline, N-acetyl aspartate (NAA), creatine, lactate, and lipid were analyzed, and the choline-tocreatine, NAA-to-creatine, lactate-to-creatine, and lipid-to-creatine ratios were recorded and compared between benign and malignant tumors.
RESULTS: A choline peak was detected in all 69 cases (100%), NAA peak in 67 cases (97%, 25 benign and 42 malignant), lipid peak in 47 cases (17 benign and 30 malignant), and lactate peak in eight cases (four benign and four malignant). The mean (± SD) choline-tocreatine ratio was 5.13 ± 0.6 in benign tumors versus 8.90 ± 0.5 in malignant solid adnexal tumors, a statistically significant difference (p = 0.000). There were no statistically significant differences between benign and malignant tumors in the NAA-to-creatine and lipid-to-creatine ratios (p = 0.263 and 0.120, respectively). When the choline-to-creatine threshold was 7.46 for differentiating between benign and malignant tumors, the sensitivity, specificity, and accuracy were 94.1%, 97.1%, and 91.2%, respectively.
CONCLUSION: Our preliminary study shows that the (1)H-MRS patterns of benign and malignant solid adnexal tumors differ. The choline-to-creatine ratio can help clinicians differentiate benign from malignant tumors.
Incidence and effects on mortality of venous thromboembolism in elderly women with endometrial cancer.
Obstet Gynecol. 2015; 125(6):1362-70 [PubMed] Related Publications
METHODS: We used the National Cancer Institute's Surveillance, Epidemiology, and End Results cancer registries linked to Medicare claim files to identify patients with epithelial endometrial cancer diagnosed between 1992 and 2009. To identify venous thromboembolism events 3 months before diagnosis and up to 24 months after diagnosis, we used International Classification of Diseases, 9th Revision, and Healthcare Common Procedure Coding System codes.
RESULTS: A total of 23,122 patients were included; of them 1,873 (8.1%) developed a venous thromboembolism. Patients with low-grade (grades 1 and 2) endometrioid adenocarcinoma had a significantly lower rate of venous thromboembolism 3 months before and 6 months after the diagnosis of cancer (3.6%; 95% confidence interval [CI] 3.3-3.9%) compared with carcinosarcoma (9.2%; 95% CI 7.8-10.8%), clear cell (6.9%; 95% CI 4.8-9.7%), uterine serous cancer (8.1%; 95% CI 7.01-9.3%), and grade 3 endometrioid adenocarcinoma (6.1%; 95% CI 5.4-6.9%) (P<.001). On multivariate analysis during the same time period, most recent time periods of diagnosis, carcinosarcoma histology compared with lower grade endometrial cancer, higher stage, African American race, marital status, chemotherapy delivery, and lymph node dissection were associated with increased risk of venous thromboembolism. The median overall survival for women who experienced a venous thromboembolism 3 months before the diagnosis of endometrial cancer was 31 months (95% CI 20-48 months); in women diagnosed with venous thromboembolism 6 months after the cancer diagnosis was 37 months (95% CI 31-44), and in women who did not experienced a venous thromboembolism was 111 months (95% CI 109-114). After adjusting for prognostic factors, there was an association between venous thromboembolism diagnosed 3 months before endometrial cancer (hazard ratio 1.69, 95% CI 1.34-2.13) or 6 months after the diagnosis (hazard ratio 1.57, 95% CI 1.44-1.71) and lower survival.
CONCLUSION: Patients with uterine serous cancer, carcinosarcoma, clear cell carcinoma, and grade 3 endometrioid adenocarcinoma had a higher rate of venous thromboembolism than patients with low-grade endometrioid adenocarcinoma. A diagnosis of venous thromboembolism was associated with decreased survival in elderly patients with endometrial cancer.

Comparing mortality of vaginal sarcoma, squamous cell carcinoma, and adenocarcinoma in the surveillance, epidemiology, and end results database.
Obstet Gynecol. 2015; 125(6):1353-61 [PubMed] Related Publications
METHODS: Women with primary invasive vaginal sarcomas, squamous cell carcinomas, and adenocarcinomas diagnosed between 1988 and 2010 were identified within the National Cancer Institute's Surveillance, Epidemiology, and End Results database. Parametric and nonparametric methods were used to compare the demographic and clinical characteristics of women among the three tumor types as well as between sarcoma histologic subtypes. Overall and cancer-specific mortality outcomes were examined using Kaplan-Meier and multivariable Cox proportional hazards models.
RESULTS: The final cohort consisted of 3,121 patients with vaginal squamous cell carcinoma, 720 patients with adenocarcinoma, and 221 patients with sarcoma. Compared with women with squamous cell carcinoma and adenocarcinoma, patients diagnosed with vaginal sarcomas tended to be younger, have larger tumors with less regional extension and lymph node positivity, and be treated primarily with surgery without radiation. In unadjusted analysis, 5-year mortality rates border 30% for all three histologies. After adjusting for other prognostic factors including use of radiation and surgery, patients with vaginal sarcomas had a 69% greater risk of cancer-related mortality compared with patients with squamous cell carcinoma (hazard ratio 1.69, 95% confidence interval 1.26-2.26). Although sarcoma histology failed to associate with mortality risk, age, tumor extension and metastasis, and surgery were poor prognostic factors.
CONCLUSION: Primary vaginal sarcomas are aggressive neoplasms with different presenting characteristics and increased adjusted risk of mortality compared with squamous cell and adenocarcinoma subtypes.

Trends in relative survival for ovarian cancer from 1975 to 2011.
Obstet Gynecol. 2015; 125(6):1345-52 [PubMed] Free Access to Full Article Related Publications
METHODS: Women diagnosed with ovarian cancer from 1975 to 2011 and recorded in the National Cancer Institute's Surveillance, Epidemiology, and End Results database were examined. Relative survival, estimated as the ratio of the observed survival of cancer patients (all-cause mortality) to the expected survival of a comparable group from the general population, was matched to the patients with the main factors that are considered to affect patient survival such as age, calendar time, and race. Hazard ratios were adjusted for age, race, year of diagnosis, time since diagnosis, and the interaction of age and years since diagnosis (except for stage II).
RESULTS: A total of 49,932 women were identified. For stage I ovarian cancer, the adjusted excess hazard ratio for death in 2006 was 0.51 (95% confidence interval [CI] 0.41-0.63) compared with those diagnosed in 1975. The reduction in excess mortality remained significant when compared with 1980 and 1985. For women with stage III-IV tumors, the excess hazard of mortality was lower in 2006 compared with all other years of study ranging from 0.49 (95% CI 0.44-0.55) compared with 1975 to 0.93 (95% CI 0.87-0.99) relative to 2000. For women aged 50-59 years, 10-year relative survival was 0.85 (99% CI 0.61-0.95) for stage I disease and 0.18 (99% CI 0.10-0.27) for stage III-IV tumors. For women aged 60-69 years, the corresponding 10-year relative survival estimates were 0.89 (99% CI 0.58-0.98) and 0.15 (99% CI 0.09-0.21).
CONCLUSION: Relative survival has improved for all stages of ovarian cancer from 1975 to 2011.
LEVEL OF EVIDENCE: II.
Augmentation of response to chemotherapy by microRNA-506 through regulation of RAD51 in serous ovarian cancers.
J Natl Cancer Inst. 2015; 107(7) [PubMed] Related Publications
METHODS: We used Kaplan-Meier and log-rank methods to analyze the relationship between miR-506 and progression-free and overall survival in The Cancer Genome Atlas (TCGA) (n = 468) and Bagnoli (n = 130) datasets, in vitro experiments to study whether miR-506 is associated with homologous recombination, and response to chemotherapy agents. We used an orthotopic ovarian cancer mouse model (n = 10 per group) to test the effect of miR-506 on cisplatin and PARP inhibitor sensitivity. All statistical tests were two-sided.
RESULTS: MiR-506 was associated with better response to therapy and longer progression-free and overall survival in two independent epithelial ovarian cancer patient cohorts (PFS: high vs low miR-506 expression; Bagnoli: hazard ratio [HR] = 3.06, 95% confidence interval [CI] = 1.90 to 4.70, P < .0001; TCGA: HR = 1.49, 95% CI = 1.00 to 2.25, P = 0.04). MiR-506 sensitized cells to DNA damage through directly targeting the double-strand DNA damage repair gene RAD51. Systemic delivery of miR-506 in 8-12 week old female athymic nude mice statistically significantly augmented the cisplatin and olaparib response (mean tumor weight ± SD, control miRNA plus cisplatin vs miR-506 plus cisplatin: 0.36±0.05g vs 0.07±0.02g, P < .001; control miRNA plus olaparib vs miR-506 plus olaparib: 0.32±0.13g vs 0.05±0.02g, P = .045, respectively), thus recapitulating the clinical observation.
CONCLUSIONS: MiR-506 is a robust clinical marker for chemotherapy response and survival in serous ovarian cancers and has important therapeutic value in sensitizing cancer cells to chemotherapy.

Primary ovarian endometrioid adenocarcinoma: magnetic resonance imaging findings including a preliminary observation on diffusion-weighted imaging.
J Comput Assist Tomogr. 2015 May-Jun; 39(3):401-5 [PubMed] Related Publications
MATERIALS AND METHODS: Twenty patients with OEC proven by surgery and pathology underwent MRI. The MRI features of the tumors evaluated included laterality, shape, size, configuration, mural nodules, signal intensity, apparent diffusion coefficient (ADC) values, enhancement, peritoneal implants, ascites, and synchronous primary cancer (SPC) of the ovary and endometrium.
RESULTS: Unilateral ovarian masses were observed in 18 (90%) of the 20 patients with 22 OEC lesions, whereas the remaining 2 (10%) patients had bilateral masses. Oval, lobulated, and irregular shapes were observed in 13 (59%), 6 (27%), and 3 (14%) tumors, respectively. The maximum diameter of the tumors ranged from 3.7 to 22.5 cm, with a mean of 11.2 ± 5.1 cm. Fifteen (68%) masses were mainly cystic with mural nodules, 5 (23%) were mixed cystic-solid, and 2 (9%) were solid. The solid components of tumors showed isointensity (100%) on T1-weighted imaging (T1WI), heterogeneous hyperintensity on T2-weighted imaging (T2WI) (86%), and hyperintensity on DWI (82%), with a mean ADC value of (0.96 ± 0.20) × 10 mm/s. The cystic components showed isointensity or hyperintensity (85%) on T1WI, hyperintensity on T2WI (100%), and hypointensity on DWI (63%), with a mean ADC value of (2.27 ± 0.27) × 10 mm/s. Ten (50%) of the patients were SPC. The mean ADC values of the solid components were (0.85 ± 0.19) × 10 mm/s and (1.08 ± 0.15) × 10 mm/s in only-OEC and SPC, respectively, with a statistically significant difference (P = 0.012).
CONCLUSIONS: Ovarian endometrioid adenocarcinoma usually appears as a large, oval, or lobulated cystic mass with mural nodules. Cystic components show isointensity or hyperintensity on T1WI, solid components and hyperintensity on T2WI and DWI. Synchronous primary cancer of the ovary endometrium is another characteristic feature of OEC.
p16/CDKN2A FISH in Differentiation of Diffuse Malignant Peritoneal Mesothelioma From Mesothelial Hyperplasia and Epithelial Ovarian Cancer.
Am J Clin Pathol. 2015; 143(6):830-8 [PubMed] Related Publications
METHODS: p16 FISH was performed in 28 DMPMs (successful in 19), 30 RMHs, and 40 EOC cases. The cutoff values of p16 FISH were more than 10% for homozygous deletion and more than 40% for heterozygous deletion.
RESULTS: According to the above criteria, nine (47.4%) of 19 successful DMPM cases were homozygous deletion positive, and three (15.8%) of 19 were heterozygous deletion positive, whereas all RMH cases were negative for the p16 deletion. In all four major histologic subtypes of EOC, neither p16 homozygous nor heterozygous deletions were detected. To differentiate DMPM from RMH or EOC, the sensitivity of the p16 homozygous deletion was 32% (9/28), and the specificity was 100%.
CONCLUSIONS: Our study suggests that p16 FISH analysis is useful in differentiating DMPM from RMH and EOC when homozygous deletion is detected.
KRAS Mutations in Mucinous Lesions of the Uterus.
Am J Clin Pathol. 2015; 143(6):778-84 [PubMed] Related Publications
METHODS: Thirty-nine cases, including 15 AMPs, nine MMs, nine MGHs, and six normal endocervical mucosas, were selected from the departmental archive. All AMP cases with follow-up biopsies or hysterectomies were reviewed. Genomic DNA was extracted from formalin-fixed, paraffin-embedded tissue and KRAS codons 12 and 13 sequence analyzed.
RESULTS: KRAS codon 12 and 13 mutations were detected in 10 (67%) of the 15 AMP cases. No KRAS mutations were identified in MMs, MGHs, and endocervical mucosas (P = .002, AMP vs MM or MGH, Fisher exact test). Most women with AMP were postmenopausal (13/15 [86.7%]) and presented with dysfunctional uterine bleeding. Among the 10 cases of AMP harboring KRAS mutations, six (60%) cases were subsequently diagnosed with carcinoma, one with atypical complex hyperplasia, and two with AMP within endometrial polyps.
CONCLUSIONS: The results suggest a possible association between KRAS mutations and mucinous differentiation in endometrial carcinogenesis. KRAS status can help in assessing benign from precursor or malignant mucinous lesions as well as differentiate endometrial lesions from those of cervical origin.
Clinico-epidemiological study of endometrial hyperplasia--a risk factor for the development of endometrial carcinoma?
Rev Med Chir Soc Med Nat Iasi. 2015 Jan-Mar; 119(1):154-61 [PubMed] Related Publications
MATERIAL AND METHODS: Our study aimed at highlighting objective criteria in establishing the morphological diagnosis and in evaluating the prognostic elements. The studied batch included 875 patients with endometrial hyperplasia and 263 patients with endometrial adenocarcinoma, who were admitted between 2003 and 2007, and the histopathologic diagnosis was obtained by processing the hysterectomy pieces. The presence of this tumour was at its highest level half-way through the study, which was in 2005.
RESULTS: According to the study, there was a higher proportion of patients with endometrial carcinoma from the urban environment (58.2%) than the ones from the rural environment (only 41.8%). Depending on their age, most cases of endometrial adenocarcinoma were diagnosed in 53-year old patients, with an average age of 58.94 years. Our study, made of the two batches of endometrial adenocarcinomas, shows that between the endometrial and non-endometrial adenocarcinoma there are significant differences related to the patients' age, the morphological aspect of the carcinoma, the architectural degree, the nuclear degree of tumours and the invasion in the myometrium.
CONCLUSIONS: Our study proves that endometrial hyperplasia is a frequent diagnosis in peri- and postmenopausal patients and is frequently identified following investigations for an abnormal uterine bleeding. The age of patients with endometrial carcinoma is an important prognostic factor independent of other parameters. The difference between complex hyperplasia with no atypias and complex hyperplasia with atypias is important, because atypical complex hyperplasia is considered the precursor of endometrial adenocarcinoma.
Trends in the quality of treatment for patients with intact cervical cancer in the United States, 1999 through 2011.
Int J Radiat Oncol Biol Phys. 2015; 92(2):260-7 [PubMed] Related Publications
METHODS AND MATERIALS: By searching diagnosis and procedure claims in MarketScan, an employment-based health care claims database, we identified 1508 patients with nonmetastatic, intact cervical cancer treated from 1999 to 2011, who were <65 years of age and received >10 fractions of radiation. Treatments received were identified using procedure codes and compared with 3 quality benchmarks: receipt of brachytherapy, receipt of chemotherapy, and radiation treatment duration not exceeding 63 days. The Cochran-Armitage test was used to evaluate temporal trends.
RESULTS: Seventy-eight percent of patients (n=1182) received brachytherapy, with brachytherapy receipt stable over time (Cochran-Armitage Ptrend=.15). Among patients who received brachytherapy, 66% had high-dose rate and 34% had low-dose rate treatment, although use of high-dose rate brachytherapy steadily increased to 75% by 2011 (Ptrend<.001). Eighteen percent of patients (n=278) received intensity modulated radiation therapy (IMRT), and IMRT receipt increased to 37% by 2011 (Ptrend<.001). Only 2.5% of patients (n=38) received IMRT in the setting of brachytherapy omission. Overall, 79% of patients (n=1185) received chemotherapy, and chemotherapy receipt increased to 84% by 2011 (Ptrend<.001). Median radiation treatment duration was 56 days (interquartile range, 47-65 days); however, duration exceeded 63 days in 36% of patients (n=543). Although 98% of patients received at least 1 benchmark treatment, only 44% received treatment that met all 3 benchmarks. With more stringent indicators (brachytherapy, ≥4 chemotherapy cycles, and duration not exceeding 56 days), only 25% of patients received treatment that met all benchmarks.
CONCLUSION: In this cohort, most cervical cancer patients received treatment that did not comply with all 3 benchmarks for quality treatment. In contrast to increasing receipt of newer radiation technologies, there was little improvement in receipt of essential treatment benchmarks.
Hypercalcemic type of small cell carcinoma of the ovary.
Vojnosanit Pregl. 2015; 72(3):295-8 [PubMed] Related Publications
CASE REPORT: A 60-year-old woman, Caucasian, came to the doctor because of discomfort in the lower abdomen and pain of greater intensity in last few days. Ultrasound examination and CT scan of the abdomen confirmed the presence of large adnexal masses of cystic-solid appearance with the largest diameter of 13 cm, regular structure of the other gynecological organs, without verifying the existence of metastatic deposits. All the results of laboratory analysis gave normal values, except for calcium, which was elevated. Explorative laparotomy with complete hysterectomy, bilateral salpingo-oophorectomy, dissection of lymph nodes and omentectomy were conducted. Based on pathohistological analysis of the operative material, SCOC at FIGO Ia stage was diag- nosed. No complications were observed in a postsurgery period and after 10 days the patient was discharged in a good condition and with normal calcemia. The treatment was continued with concurrent radiotherapy and chemotherapy. However, in spite of overall treatment, the disease progressed, and the patient died of disseminated metastatic disease, 26 months after the diagnosis.
CONCLUSION: Small cell carcinoma localized in the ovary is generally a tumor category with bad prognosis depending on the stage of the disease.
