2-Deoxy-glucose Enhances the Effect of Cisplatin and Pemetrexed in Reducing Malignant Pleural Mesothelioma Cell Proliferation But Not Spheroid Growth.
Anticancer Res. 2019; 39(7):3809-3814 [PubMed] Related Publications
MATERIALS AND METHODS: MeT-5A, M14K, MSTO and ZL34 cell lines were used. Cell viability with 2DG and cell proliferation and spheroid formation with CPDD+PEM alone and with 2-DG were tested.
RESULTS: Viability with 2-DG was dose-dependent. Cell proliferation with CPDD+PEM on 2D surface was reduced in all cell types, 2-DG inclusion demonstrated a synergistic effect in MSTO and ZL34 cells. Spheroid growth in 3D with CPDD+PEM or CPDD+PEM+2-DG lowered spheroid growth in all cell types.
CONCLUSION: 2-DG synergizes with CPDD+PEM in lowering MPM cell proliferation in 2D to <20%. In 3D MPM spheroid growth 2-DG synergism with CPDD+PEM treatment is not maintained.

Synchronous occurrence of benign mesothelioma and adenomatoid tumor of uterus: A case report and review of literature.
Medicine (Baltimore). 2019; 98(20):e15746 [PubMed] Free Access to Full Article Related Publications
PATIENT CONCERNS: A case of benign mesothelial combined with uterus adenomatoid tumor (UAT) in a 48-year-old Chinese woman was reported. Our patient presented with abdominal pain and surgery showed a large subserous mass (12.0 × 11.4 × 9.8 cm) combined with a small intramural solid nodule (2.0 × 1.0 × 1.0 cm), and multiple minute neoplastic growth on the ovary.
DIAGNOSIS: Due to the patient's symptoms, pathological findings, she was diagnosed with synchronous occurrence of benign mesothelioma and UAT.
INTERVENTIONS: We treated her with a total hysterectomy and bilateral adnexectomy.
OUTCOMES: The patient is now in stable condition, without any signs of recurrence during 1 year of follow-up.
LESSONS: Most mesotheliomas are malignant, synchronous occurrence of benign mesothelioma and UAT are extremely rare. And they are often misdiagnosed as malignancy by clinicians. Our case report can improve the awareness of the disease and avoid excessive treatment.

Physician requests by patients with malignant pleural mesothelioma in Japan.
BMC Cancer. 2019; 19(1):383 [PubMed] Free Access to Full Article Related Publications
METHODS: This cross-sectional survey was part of a larger study (N = 133) regarding the quality of life of MPM patients. Specific responses to two open-ended questions related to patients' requests regarding treatment and care were quantified, analyzed and divided into categories based on content.
RESULTS: Responses (N = 217) from MPM patients (N = 73) were categorized into 24 subcategories and then abstracted into 6 categories. The majority of requests were related to patient-physician communication. Patients wanted clear and understandable explanations about MPM and wanted their physician to deliver treatment based on the patient's perspective by accepting and empathizing with their anxiety and pain. Patients expected physicians to be dedicated to their care and establish an improved medical support system for MPM patients.
CONCLUSION: Patients with MPM had a variety of unmet needs from their physicians. Physicians who provide care to MPM patients should receive training in both communication skills and stress management. A multidisciplinary care system that includes respiratory and palliative care for MPM patients should be established.
Primary malignant mesothelioma of the diaphragm with liver invasion: A case report and review of literature.
Medicine (Baltimore). 2019; 98(15):e15147 [PubMed] Free Access to Full Article Related Publications
PATIENT CONCERNS: A 66-year-old woman was admitted to our hospital because of a "liver space-occupying lesion," without any special clinical symptoms. Imaging examinations suggested a cystic-solid mixed lesion in the right lobe of the liver.
DIAGNOSIS: The tumor was diagnosed as epithelioid mesothelioma of the diaphragm with liver invasion.
INTERVENTION: The patient underwent abdominal surgery in our hospital to remove the diaphragmatic mass, liver mass, and part of the diaphragm.
OUTCOMES: The postoperative course was uneventful.
LESSONS: Primary diaphragmatic malignant mesothelioma is very rare and may involve liver or lung tissue and be mistaken for liver or lung tumor. Accurate diagnosis depends on careful pathological examination. Immunohistochemical staining is very useful to distinguish this tumor from other liver or diaphragmatic tumors.

METHODS: Medline, Embase, Web of Science, and Cochrane library system were systematically searched on the data of SMRPs in PE for MPM diagnosis. Pooled diagnostic sensitivity, specificity, and symmetric receiver operating characteristic curve were calculated.
RESULTS: Thirteen studies fulfilled the inclusion criteria and a total of 3359 cases including 759 MPM cases, 1061 non-MM (malignant mesothelioma) malignant PE, and 1539 benign PE were brought into this meta-analysis. The pooled results of SMRPs in PE for diagnosing MPM were as follows: sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, and diagnostic odds ratio were 0.68 (95% confidence interval [CI]: 0.64-0.72), 0.91 (95% CI: 0.86-0.94), 7.8 (95% CI: 5.0-12.0), 0.35 (95% CI: 0.31-0.40), and 22 (95% CI: 14-35), respectively. The area under the summary receiver operating characteristic curves (AUC) was 0.75 (95% CI: 0.72-0.80). Subgroup analyzes revealed that the AUC of cohort group using histological diagnosis could be improved to 0.86 (95% CI: 0.83, 0.89). The Deek's funnel plot asymmetry test showed no publication bias.
CONCLUSION: Although the sensitivity of SMRPs was low, PE-SMRPs can be a good indicator of the existence of MPM.

Prognostic Factors of Malignant Peritoneal Mesothelioma Experienced in Japanese Peritoneal Metastasis Center.
Gan To Kagaku Ryoho. 2019; 46(2):395-399 [PubMed] Related Publications
METHODS: Among 63 patients with MPM, male and female patients were 34 and 29. CRSwas performed in 47 patients and complete cytoreduction(CC-0) was performed in 14(22%)patients. Mean numbers of resected peritoneal sectors and organs were 5.2(1-13), and 2.9(0- 9), respectively. Hyperthermic intraperitoneal chemoperfusion(HIPEC)was performed in 27 patients. Grade 1/2, Grade 3, and Grade 4 complications were experienced in 5, 6, and 3 patients, respectively. One patient died of sepsis, and the mortality rate was 2.3%. Independent prognostic factors for favorable prognosis were performance of HIPEC, peritoneal cancer index (PCI)score C12, no distant metastasis and histologic epithelial type. Relative risk of no HIPEC, PCI score B13, presence of distant metastasis and non epithelial type were 7.69, 22.1, 3.6 and 3.9, respectively.
CONCLUSIONS: Risk factors for death after comprehensive treatment were no HIPEC, PCI score B13, and non epithelial type. However, only 11(17%)patients showed PCI score C12. Accordingly, PCI score should be reducedC12 before CRSby neoadjuvant chemotherapy.

Cryobiopsy during flex-rigid pleuroscopy: an emerging alternative biopsy method in malignant pleural mesothelioma. A comparative study of pathology.
Jpn J Clin Oncol. 2019; 49(6):559-566 [PubMed] Related Publications
METHODS: Consecutive patients who underwent pleural cryobiopsy during flex-rigid pleuroscopy from June through November 2017 to diagnose the cause of pleural effusion were collected. From these, cases ultimately diagnosed as MPM were selected. Pleural biopsies were performed by using conventional instruments followed by a cryoprobe. The obtained samples were histologically examined and compared with regard to the quality (sample size, tissue depth, and crush rate), immunohistochemical (IHC) staining, and p16 by fluorescence in situ hybridization (FISH).
RESULTS: In total, five patients ultimately diagnosed as MPM were enrolled. The sample collected was significantly larger for cryobiopsy than conventional biopsy (18.9 mm2 vs. 6.7 mm2, P < 0.001). Full-thickness biopsies were achieved in four cases by using cryobiopsy compared with one case by conventional biopsy. Moreover, the crush rate was significantly less for cryobiopsy than conventional biopsy (9% vs. 35%, P < 0.001). The results of IHC staining and p16 by FISH were similar between biopsy techniques. Cryobiopsy successfully led to accurate diagnosis of MPM in all cases, whereas conventional biopsy was diagnostic in one case. No severe complications developed after either biopsy technique.
CONCLUSION: Cryobiopsy during flex-rigid pleuroscopy is a feasible and convenient biopsy technique that supports precise diagnosis of MPM.
Localized multiple malignant epithelioid peritoneal mesotheliomas arising from the hepatoduodenal ligament and diaphragm: a case report.
J Med Case Rep. 2019; 13(1):66 [PubMed] Free Access to Full Article Related Publications
CASE PRESENTATION: A 55-year-old Japanese woman was admitted to our hospital because liver tumors were detected by abdominal ultrasonography during a screening examination. Blood examination findings, including tumor makers, were within normal ranges. She had no evidence of exposure to asbestos. Computed tomography showed four hypervascular, round liver tumors, one in the lateral liver segment adjacent to the hepatic hilus, and the other three on the liver surface. Computed tomography angiography revealed that the tumor in the lateral segment had strong enhancement and was fed from the left gastric artery. In contrast, the other tumors showed no enhancement, and were fed from the right inferior phrenic artery. Abnormal accumulation was identified in the four tumors only with
CONCLUSIONS: In general, malignant peritoneal mesotheliomas are classified as diffuse tumors, which are often unresectable and have a poor prognosis. However, early diagnosis and treatment, particularly with the localized type, as in our patient, could lead to long-term survival of the patient. We recommend that multiple malignant epithelioid mesotheliomas be included in the differential diagnosis for patients with subcapsular hepatic tumors.
Dynamic contrast-enhanced MRI of malignant pleural mesothelioma: a comparative study of pharmacokinetic models and correlation with mRECIST criteria.
Cancer Imaging. 2019; 19(1):10 [PubMed] Free Access to Full Article Related Publications
METHOD: This prospective, longitudinal, single tertiary radiology center study was conducted between October 2013 and July 2015. Patient underwent DCE-MRI studies at three time points: prior to therapy, during and after cisplatin-based chemotherapy. The images were analyzed using ET and AATH models. In short-term follow-up, the patients were classified as having disease control or progressive disease according to modified response evaluation criteria in solid tumors (mRECIST) criteria. Receiver operating characteristic curve analysis was used to examine specificity and sensitivity of DCE parameters for predicting response to therapy. Comparison tests were used to analyze whether derived parameters are interchangeable between the two models.
RESULTS: Nineteen patients form the study population. The results indicate that the derived parameters are not interchangeable between the models. Significant correlation with response to therapy was found for AATH-calculated median pre-treatment efflux rate (k
CONCLUSION: Both models show potential in predicting response to therapy in MPM. High pre-treatment k
About the diagnostic value of BAP-1 antibody in malignant pleural mesothelioma: a meta-analysis.
J Immunoassay Immunochem. 2019; 40(3):269-282 [PubMed] Related Publications
METHODS: We performed a meta-analysis using the Meta-Disc software 5.1.32.
RESULTS: According to our inclusion criteria, 19 studies with 11 studies dealing with BAP1 antibody and 8 studies dealing with calretinin antibody were included. The SEN of BAP 1 and calretinin antibodies was respectively estimated to 54.6% and 86.5%. The SPE reached respectively 95.7% and 76.6%. The dOR was estimated respectively to 23.664 and 38.8. The I-square revealed a heterogeneity of the parameters studied. The metaregression analysis revealed as covariates the amplification system and the histologic subtype as causing effects of heterogeneity for BAP1 antibodies and histologic subtype and chromogene as causing effects of heterogeneity for calretinin antibody.
CONCLUSION: This meta-analysis revealed that BAP1 antibody should be associated with more sensitive antibodies in order to assess the diagnosis.
Clinicopathological Characteristics of Well-differentiated Papillary Mesothelioma of The Peritoneum: A Single-institutional Experience of 12 Cases.
In Vivo. 2019 Mar-Apr; 33(2):633-642 [PubMed] Free Access to Full Article Related Publications
MATERIALS AND METHODS: The clinicopathological characteristics and immunophenotype of 12 cases of peritoneal WDPM were investigated using a review of electronic medical records, pathological examination, and immunostaining.
RESULTS: The patients' ages ranged from 23 to 75 years. No patient had endometriosis or a previous history of asbestos exposure. Ten tumors were detected incidentally during surgery for other causes. Most tumors appeared as a small, single nodule on the peritoneal surface, but in three cases, WDPM presented as multiple lesions. All but one patient had no symptoms. All the patients examined are still well without postoperative recurrence. Histologically, all cases demonstrated typical papillary architecture with fibrovascular cores. The mesothelial cells lining the papillae consisted mostly of single row of cells, although areas of proliferation to multiple layers were observed in a few cases. Their nuclei appeared bland, but two cases exhibited mild nuclear atypia and prominent nucleoli. Immunostaining revealed that the mesothelial cells were positive for D2-40, cytokeratin 5/6, cytokeratin 7, and Wilms' tumor 1.
CONCLUSION: We herein demonstrated the clinicopathological characteristics of peritoneal WDPMs. WDPM has distinct pathological features. Although all cases we examined were uneventful after surgery, further surveillance is recommended since the biological behavior of WDPM is still uncertain.

BAP1 haploinsufficiency predicts a distinct immunogenic class of malignant peritoneal mesothelioma.
Genome Med. 2019; 11(1):8 [PubMed] Free Access to Full Article Related Publications
METHODS: To search for novel therapeutic targets for PeM, we performed a comprehensive integrative multi-omics analysis of the genome, transcriptome, and proteome of 19 treatment-naïve PeM, and in particular, we examined BAP1 mutation and copy number status and its relationship to immune checkpoint inhibitor activation.
RESULTS: We found that PeM could be divided into tumors with an inflammatory tumor microenvironment and those without and that this distinction correlated with haploinsufficiency of BAP1. To further investigate the role of BAP1, we used our recently developed cancer driver gene prioritization algorithm, HIT'nDRIVE, and observed that PeM with BAP1 haploinsufficiency form a distinct molecular subtype characterized by distinct gene expression patterns of chromatin remodeling, DNA repair pathways, and immune checkpoint receptor activation. We demonstrate that this subtype is correlated with an inflammatory tumor microenvironment and thus is a candidate for immune checkpoint blockade therapies.
CONCLUSIONS: Our findings reveal BAP1 to be a potential, easily trackable prognostic and predictive biomarker for PeM immunotherapy that refines PeM disease classification. BAP1 stratification may improve drug response rates in ongoing phases I and II clinical trials exploring the use of immune checkpoint blockade therapies in PeM in which BAP1 status is not considered. This integrated molecular characterization provides a comprehensive foundation for improved management of a subset of PeM patients.
Pemetrexed-loaded nanoparticles targeted to malignant pleural mesothelioma cells: an in vitro study.
Int J Nanomedicine. 2019; 14:773-785 [PubMed] Free Access to Full Article Related Publications
Methods: MPM cell lines and primary cultures obtained by pleural effusions from MPM patients were assayed for CD146 expression by flow cytometry. Internalization by MPM cell lines of fluorescent dye-marked GNPs decorated with a monoclonal anti CD146 coated GNPs (GNP-HC) was proven by confocal microscopy. The effects of anti CD146 coated GNPs loaded with Pe (GNP-HCPe) on MPM cell lines were evaluated by cell cycle (flow cytometry), viability (MTT test), clonogenic capacity (soft agar assay), ROS production (electric paramagnetic resonance), motility (wound healing assay), and apoptosis (flow cytometry).
Results: GNP-HC were selectively uptaken by MPM cells within 1 hour. MPM cell lines were blocked in the S cell cycle phase in the presence of GNP-HCPe. Both cell viability and motility were significantly affected by nanoparticle treatment compared to Pe. Apoptotic rate and ROS production were significantly higher in the presence of nanoparticles. Clonogenic capacity was completely inhibited following nanoparticle internalization.
Conclusion: GNP-HCPe treatment displays in vitro antineoplastic action and is more effective than Pe alone in inhibiting MPM cell line malignant phenotype. The innovative use of specifically targeted GNPs opens the perspective of local intrapleural administration to avoid normal cell toxicity and enhance chemotherapy efficacy.

Are circulating microRNAs suitable for the early detection of malignant mesothelioma? Results from a nested case-control study.
BMC Res Notes. 2019; 12(1):77 [PubMed] Free Access to Full Article Related Publications
RESULTS: Using prediagnostic plasma samples collected in median 8.9 months prior the clinical diagnosis miR-132-3p, miR-126-3p, and miR-103a-3p revealed 0% sensitivity on a defined specificity of 98%. Thus, the analyzed miRNAs failed to detect the cancer in prediagnostic samples, showing that they are not feasible for the early detection of malignant mesothelioma. However, the miRNAs might still serve as possible markers for prognosis and response to therapy, but this needs to be analyzed in appropriate studies.
Malignant Peritoneal Mesothelioma: Treatment Options and Survival.
Anticancer Res. 2019; 39(2):839-845 [PubMed] Related Publications
MATERIALS AND METHODS: The data consisted of all patients diagnosed with MPeM during years 2000-2012 in Finland, including cancer notifications, death certificates and information about asbestos exposure.
RESULTS: Among 50/94 (53.2%) patients treated for MPeM, 44/50 (88.0%) were treated palliatively, 4/50 (8.0%) with radical surgery and chemotherapy, and 2/50 (4.0%) with CRS plus HIPEC. Five-year survival was 50.0% for those treated with CRS plus HIPEC and 75.0% for those treated with radical surgery and chemotherapy. Radical surgery with chemotherapy was associated with significantly longer survival compared to radiation (p=0.008), chemotherapy and radiation (p=0.043), surgery, chemotherapy and radiation (p=0.039), and palliative surgery (p=0.009).
CONCLUSION: Treatment of MPeM is heterogenic in Finland. CRS plus HIPEC, and radical surgery with chemotherapy seem to increase the survival. Patients considered candidates for radical surgery should be sent to specialized centers for further assessment.
Tenascin XB Is a Novel Diagnostic Marker for Malignant Mesothelioma.
Anticancer Res. 2019; 39(2):627-633 [PubMed] Related Publications
MATERIALS AND METHODS: TNXB gene expression was found to be significantly higher in MM tumor tissues compared to paired normal tissues, as assessed by the Gene Expression Omnibus database. The inhibition of TNXB using small interfering RNAs suppressed the proliferation and colony formation of MM cells. Expression of TNXB and calretinin, a current diagnostic marker of MM, was evaluated by immunohistochemistry.
RESULTS: The sensitivity and specificity of TNXB for MM were 80.0% and 69.5%, respectively. When the detection of TNXB was combined with that of calretinin, 83.3% of MM cases were detected.
CONCLUSION: These findings suggest that TNXB is a novel diagnostic biomarker for MM. A combination of detecting TNXB and calretinin may be useful for the differential diagnosis of MM from lung adenocarcinoma.
