Abstract
Introduction Malignant peritoneal mesothelioma (MPM) is a rare cancer that is associated with asbestos exposure. The diagnosis can be difficult given the nonspecific nature of presenting symptoms and the presence of concomitant confounding findings. Case Presentation We report a 71-year-old male who presented with right lower quadrant pain and new-onset ascites. CT imaging of the abdomen/pelvis demonstrated omental stranding concerning for a possible omental infarction. Subsequent imaging showed persistent omental edema but no identifiable soft tissue mass. A biopsy of the omentum showed atypical mesothelial proliferation, but pathology was unable to determine if proliferation was a neoplastic versus reactive process. Surgical oncology performed a diagnostic laparoscopy that showed peritoneal studding of the omentum. Subsequent immunohistochemical staining of the omentum demonstrated preservation of BAP1 expression and loss of MTAP expression, consistent with peritoneal mesothelioma. Conclusion MPM is a rare and aggressive cancer with an overall poor prognosis. The diagnosis of MPM can be difficult based on the nonspecific clinical presentation, insufficient imaging and laboratory testing, and the presence of concomitant confounding findings, such as with this patient and his admitting diagnosis of omental infarction. This case demonstrates the importance of developing a broad differential while maintaining an awareness of heuristics that can influence clinical decision-making.

Abstract
BACKGROUND Thoracic empyema and malignant pleural mesothelioma (MPM) are distinct medical conditions with similar symptoms, including cough, chest pain, and breathing difficulty. We present a rare MPM case mimicking thoracic empyema. Physicians must consider MPM risks for patients exposed to building material who exhibit lobulated pleural effusions, indicating thoracic empyema. CASE SUMMARY A 68-year-old retired male construction worker suffered from shortness of breath and chest tightness over 10 d, particularly during physical activity. A poor appetite and 4 kg weight loss over the past 3 wk were also reported. Chest images and laboratory data concluded a tentative impression of empyema thoracis (right). Video-assisted thoracic surgery with decortication and delobulation (right) was conducted. The pathological report yielded an MPM diagnosis. Refractory pleural bilateral effusions and respiratory failure developed postoperatively, and the patient died three weeks after the operation. CONCLUSION Thoracic empyema and MPM are distinct medical conditions that can present similar symptoms, and video-assisted thoracic surgery facilitates an accurate diagnosis. Empyema-mimicking presentations and postoperative refractory pleural effusion may indicate a poor MPM outcome.

Abstract
Malignant mesothelioma (MM) is a rare aggressive tumor, and bone metastasis often occurs in later stages of this disease. This study aimed to establish a nomogram to predict the prognosis of bone metastasis of patients with MM. Data from the Surveillance, Epidemiology, and End Results database were screened and retrieved. This study included 311 patients with MM with bone metastases. Prognostic factors were analyzed using the Kaplan-Meier method and Cox proportional hazards model. A nomogram for overall survival (OS) was established and evaluated using statistically significant prognostic factors, and cancer-specific survival (CSS) analysis was performed to investigate its prognostic factors. In addition, the metastasis patterns of patients with MM were investigated, and the effects of different sites of metastasis on survival were compared using the Kaplan-Meier method. Age, sex, histological type, and chemotherapy were identified as the independent risk factors for OS. The 1-, 2-, and 3-year areas under the curve of the nomogram were 0.792, 0.774, and 0.928, and 0.742, 0.733, and 0.733 in the training and validation sets, respectively. Compared to OS, histological type, radiotherapy, and chemotherapy were independent risk factors for CSS. Different metastatic sites in MM have significantly different effects on prognosis.

Abstract
Malignant peritoneal mesothelioma (MPM) is a rare malignancy, presenting with non-specific and potentially-misleading manifestations. It represents a diagnostic pitfall as it mimics ovarian carcinoma. Maintaining a low diagnostic threshold, obtaining a detailed history, and utilizing immunohistochemical markers to diagnose MPM is crucial as early diagnosis and treatment might improve survival.

Abstract
Mesothelioma is a dangerous, violent cancer, which forms a protecting layer around inner tissues such as the lungs, stomach, and heart. We investigate numerous AI methodologies and consider the exact DM conclusion outcomes in this study, which focuses on DM determination. K-nearest neighborhood, linear-discriminant analysis, Naive Bayes, decision-tree, random forest, support vector machine, and logistic regression analyses have been used in clinical decision support systems in the detection of mesothelioma. To test the accuracy of the evaluated categorizers, the researchers used a dataset of 350 instances with 35 highlights and six execution measures. LDA, NB, KNN, SVM, DT, LogR, and RF have precisions of 65%, 70%, 92%, 100%, 100%, 100%, and 100%, correspondingly. In count, the calculated complication of individual approaches has been evaluated. Every process is chosen on the basis of its characterization, exactness, and calculated complications. SVM, DT, LogR, and RF outclass the others and, unexpectedly, earlier research.

Abstract
Background Malignant pleural mesothelioma (MPM) is an aggressive and rare tumour with poor prognosis. Most patients are diagnosed with advanced disease and there is a paucity of data on the humanistic burden of MPM in terms of impact on health-related quality of life (HRQoL) and activity. This study examined real-world treatment patterns and humanistic disease burden of MPM in Europe. Methods Physicians abstracted demographic/clinical characteristics and treatment data from MPM-patient medical records; MPM patients self-completed a questionnaire including symptoms, 3-level-EQ-5D questionnaire and Visual Analogue Scale (VAS), Lung Cancer Symptom Scale for Mesothelioma (LCSS-Meso), and Work Productivity and Activity Impairment (WPAI) questionnaire. Results Physicians (n = 171) abstracted data of 1390 patients; 767/1390 patients self-completed questionnaires. Patients were elderly with advanced, unresectable MPM. Treatment patterns followed guidelines with most (81%) patients receiving platinum+antifolate chemotherapy at first line (1 L). Maintenance treatment use was high (51.1%) despite no recommended maintenance therapies. Symptom burden was high and health states and HRQoL were poor at 1; declining further with progression. Overall mean (SD): LCSS-Average Symptom Burden Index score was 48.8 (19.3; n = 758); EQ-5D Utility Index score was 0.510 (0.349; n = 763); EQ-5D VAS score was 54.2 (20.3;n = 766); LCSS-3-Item Global Index score was 143.2 (64.5; n = 762); LCSS-normal activities score was 51.9 (24.6;n = 765); WPAI-activity impairment was 56.0% (23.2%; n = 737). Conclusion The humanistic burden of MPM is high, despite treatments being prescribed as per available guidance. Treatments that delay progression and provide palliation of symptoms are most likely to improve/maintain HRQoL.

Abstract
Objectives Malignant pleural mesothelioma (MPM) is an occupational disease mainly due to asbestos exposure. Effective therapies for MPM are lacking, making this tumour type a fatal disease. Materials and Methods In order to meet this need and in view of a future "drug repositioning" approach, here we screened five MPM (Mero-14, Mero-25, IST-Mes2, NCI-H28 and MSTO-211H) and one SV40-immortalized mesothelial cell line (MeT-5A) as a non-malignant model, with a library of 1170 FDA-approved drugs. Results Among several potential compounds, we found that fludarabine (F-araA) and, to a lesser extent, risedronic acid (RIS) were cytotoxic in MPM cells, in comparison to the non-malignant Met-5A cells. In particular, F-araA reduced the proliferation and the colony formation ability of the MPM malignant cells, in comparison to the non-malignant control cells, as demonstrated by proliferation and colony formation assays, in addition to measurement of the phospho-ERK/total-ERK ratio. We have shown that the response to F-araA was not dependent upon the expression of DCK and NT5E enzymes, nor upon their functional polymorphisms (rs11544786 and rs2295890, respectively). Conclusion This drug repositioning screening approach has identified that F-araA could be therapeutically active against MPM cells, in addition to other tumour types, by inhibiting STAT1 expression and nucleic acids synthesis. Further experiments are required to fully investigate this.

Abstract
Oncolytic adenoviral immunotherapy activates the innate immune system with subsequent induction of adaptive tumor‐specific immune responses to fight cancer. Hence, oncolytic viruses do not only eradicate cancer cells by direct lysis, but also generate antitumor immune response, allowing for long‐lasting cancer control and tumor reduction. Their therapeutic effect can be further enhanced by arming the oncolytic adenovirus with costimulatory transgenes and/or coadministration with other antitumor therapies. ONCOS‐102 has already been found to be well tolerated and efficacious against some types of treatment‐refractory tumors, including mesothelin‐positive ovarian cancer (NCT01598129). It induced local and systemic CD8+ T‐cell immunity and upregulated programmed death ligand 1. These results strongly advocate the use of ONCOS‐102 in combination with other therapeutic strategies in advanced and refractory tumors, especially those expressing the mesothelin antigen. The in vivo work presented herein describes the ability of the oncolytic adenovirus ONCOS‐102 to induce mesothelin‐specific T‐cells after the administration of the virus in bagg albino (BALB/c) mice with mesothelin‐positive tumors. We also demonstrate the effectiveness of the interferon‐γ the enzyme‐linked immunospot (ELISPOT) assay to detect the induction of T‐cells recognizing mesothelin, hexon, and E1A antigens in ONCOS‐102‐treated mesothelioma‐bearing BALB/c mice. Thus, the ELISPOT assay could be useful to monitor the progress of therapy with ONCOS‐102.

Abstract
Background Asbestos is a harmful and exceptionally persistent natural material. Malignant mesothelioma (MM), an asbestos-related disease, is an insidious, lethal cancer that is poorly responsive to current treatments. Minimally invasive, specific, and sensitive biomarkers providing early and effective diagnosis in high-risk patients are urgently needed. MicroRNAs (miRNAs, miRs) are endogenous, non-coding, small RNAs with established diagnostic value in cancer and pollution exposure. A systematic review and a qualitative meta-analysis were conducted to identify high-confidence miRNAs that can serve as biomarkers of asbestos exposure and MM. Methods The major biomedical databases were systematically searched for miRNA expression signatures related to asbestos exposure and MM. The qualitative meta-analysis applied a novel vote-counting method that takes into account multiple parameters. The most significant miRNAs thus identified were then subjected to functional and bioinformatic analysis to assess their biomarker potential. Results A pool of deregulated circulating and tissue miRNAs with biomarker potential for MM was identified and designated as “mesomiRs” (MM-associated miRNAs). Comparison of data from asbestos-exposed and MM subjects found that the most promising candidates for a multimarker signature were circulating miR-126-3p, miR-103a-3p, and miR-625-3p in combination with mesothelin. The most consistently described tissue miRNAs, miR-16-5p, miR-126-3p, miR-143-3p, miR-145-5p, miR-192-5p, miR-193a-3p, miR-200b-3p, miR-203a-3p, and miR-652-3p, were also found to provide a diagnostic signature and should be further investigated as possible therapeutic targets. Conclusion The qualitative meta-analysis and functional investigation confirmed the early diagnostic value of two miRNA signatures for MM. Large-scale, standardized validation studies are needed to assess their clinical relevance, so as to move from the workbench to the clinic.

Abstract
Primary pericardial malignant mesothelioma (PPM) is a very rare malignancy, with an incidence of less than 0.002% and represents less than 5% of all mesotheliomas. The cause of pericardial mesothelioma is uncertain that differ from pleural mesothelioma which is associated with asbestos exposure. This malignancy is terribly aggressive and has very poor prognosis with less than six months of overall survival. We present a case of a 71-year-old woman who was diagnosed with cardiac tamponade caused by PPM and received chemotherapy with pemetrexed and cisplatin for six months. During two years she was alive without disease progression. To better understand the clinical, pathologic features and treatment outcome of this entity, we reviewed 23 cases described in the English literature from 2009, together with our case, provided a total of 24 cases. Based on this review, we suggest that PPM must be considered in patients who have unexplained massive pericardial effusion and recommend chemotherapy with pemetrexed and cisplatin for the better outcome of PPM.

Abstract
Serological analysis of recombinant tumor cDNA expression library (SEREX) is a powerful and widely used method to explore the cancer immune environment. In the present study, immunoscreening of normal testicular tissues and malignant mesothelioma (MM) cancer MSTO-211H cell line cDNA libraries with sera from 5 MM patients led to the isolation of 16 independent antigens, which were designated ‘Korea Pusan-Malignant Mesothelioma’ (KP-MM)-1 to −16. In total, 3/16 antigens were identified using the results of previous SEREX analyses, and 13 were newly identified. Of these, KP-MM-8, which was subsequently identified as amyotrophic lateral sclerosis 2 chromosome region candidate 11, was shown to be tissue-restricted. Reverse transcription-polymerase chain reaction demonstrated KP-MM-8 to be expressed strongly only in the normal testis, and weakly in the spleen, prostate, ovary, heart and skeletal muscle. In addition, KP-MM-8 mRNA was identified in MM cell lines, and in various other cancer cell lines, including MM (3/4), lung cancer (5/7), melanoma (5/7) and liver cancer (5/5) cell lines. Additionally, 2/16 antigens (KP-MM-2 and KP-MM-6) exclusively reacted with sera from cancer patients. However, KP-MM-8 reacted with 1 of 8 MM sera. Notably, 8/8 patients with MM and 8/8 normal individuals exhibited antibodies reactive to KP-MM-5, which was identified as cell division cycle 25B, a known oncogene. Overall, this data suggests that KP-MM-8 may be considered as a cancer/testis-like antigen and KP-MM-5 as an immunogenic tumor antigen in MM patients.

Abstract
Malignant mesothelioma is a rare type of cancer, most commonly associated with exposure to asbestos. Mesothelioma of the peritoneum, the membrane lining the abdominal cavity, is extremely rare. The current study reports the case of a 60-year-old female who presented with intestinal fistula, recurrent incisional hernia and abdominal infection, with no history of asbestos exposure, and was diagnosed with clear cell MPM. Computed tomography scans of the abdomen revealed extensive small bowel adhesions and massive peritoneal effusion. Histological examination of biopsy specimens indicated a diagnosis of malignant peritoneal mesothelioma with clear cell morphology. A laparotomy was performed, with subsequent resection of the bowel with fistula. Follow-up examination performed at 1-year post-surgery revealed that the patient was alive and in generally good health.

Peritoneal mesothelioma metastasis to the tongue - Comparison with 8 pleural mesothelioma reports with tongue metastases. Ann Med Surg (Lond) 2015; 5:101-5. [PMID: 26900461 PMCID: PMC4724036 DOI: 10.1016/j.amsu.2015.12.059] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2015] [Revised: 12/22/2015] [Accepted: 12/22/2015] [Indexed: 12/18/2022] Open
Abstract
Purpose Malignant mesothelioma (MM) rarely arises from the peritoneum. We describe the 1st such case which metastasised to the head and neck region (tongue). Methods We briefly surveyed the American Surveillance Epidemiology and End Results (SEER) database, and the British Cancer Research UK database for the latest trends in MM incidence. We did a systematic Pubmed search for other MM reports with tongue metastases. Results and presentation of case American and British data show that MM incidence in men has stabilised in the last 10 years, earlier than previously predicted. The tongue is an unusual site for MM spread, with ours being only the 9th such case described. Our summary of published cases of MM metastasising to the tongue brings out our patient to be the least in age(35 years), and the only one to have peritoneal MM as the primary. Seven of the 9 cases were male. Only 2 had a recorded history of exposure to asbestos. All 9 patients had the epithelioid subtype of MM. Surgery was done as the exclusive reported intervention in 4 out of the 9 patients. Only 2 cases received radiotherapy, amongst whom, only our patient responded. Conclusions Metastasis of MM to the tongue is rare and usually in the uncommon context of MM with multiple sites of extra-thoracic or extra-abdominal spread. We have described a unique clinical manifestation of a rare subtype of mesothelioma. Moreover, we have tabulated and summarised details (including responses to surgery or/and radiotherapy) regarding all reported cases of mesotheliomas with tongue metastasis. MM incidence in “Western” men has stabilised in the last 10 years. Our case of MM with tongue metastasis was unfortunately very young, in fact the least aged amongst all reported cases. Our case is the only recorded one with peritoneal MM metastasising to the tongue. Our case probably presents an unusual pattern of mesothelioma metastatic progression, specifically from the abdomen to the chest, and from there, to the oral cavity. All reports of MM with tongue metastases concisely tabulated and compared.

Abstract
Malignant peritoneal mesothelioma (MPM) is a rare but fatal tumor. The clinical presentations and imaging findings are nonspecific and resemble various diseases, including peritoneal metastasis. Imaging findings of MPH on (18)F-(18)F-fluorodeoxyglucose ((18)F-FDG) positron emission tomography (PET)/computed tomography (CT) are diverse and not well described. We report the two cases of biopsy-proven MPH using (18)F-FDG PET/CT. In our cases, interesting disease patterns-including MPH arising from visceral peritoneal lining of kidney that suffer from polycystic disease and from the parietal peritoneum beneath the appendectomy scar-were presented. One case showed classical metastases localized within the abdominal cavity; while the other case exhibited the rare pattern of extensive multi-organ metastases. By knowing the possible variations and diagnostic pitfalls of (18)F-FDG PET/CT findings in MPM, more accurate interpretation of such mysterious cancer is attainable.

Abstract
Chylothorax is characterized by fluid accumulation in the pleural cavity containing chylomicrons due to disruption of lymphatic drainage in the thoracic ductus and development of chylothorax. A 60-year-old male patient presented to our clinic with shortness of breath and displayed bilateral pleural effusion and diffuse mediastinal lymph nodes in his computed chest tomography images. There were no thickening and nodular formation on the pleural surfaces. PET-CT showed no pathological FDG uptake. Thoracentesis showed a chylous effusion. Drainage reduced during monitoring could not be stopped; therefore, surgical intervention was considered. The patient underwent right thoracotomy. There were no pathological findings in the parietal and visceral pleura during the surgery. Initially lymphoma was considered. Perioperative samples were collected from the mediastinal lymph node. The pathology analysis reported metastasis of malignant mesothelioma. Evaluation of a repeated chest computed tomography showed nodular formations on the pleural surfaces. Mediastinal lymph nodes compressed the ductus thoracicus, resulting with chylothorax. The present case, with malignant mesothelioma, bilateral chylothorax, and mediastinal lymph node without any pleural involvement during initial diagnosis, is rare and will hence contribute to the literature.

Abstract
We report a case of KL-6 producing peritoneal malignant mesothelioma. A 56-year-old woman was referred to our hospital on November 2005 with severe abdominal distention. Peritoneal malignant mesothelioma with epithelioid type was diagnosed by clinical symptoms, laboratory investigations, imaging studies, and immunohistochemical examination of known tumor markers. In addition, high serum and ascitic KL-6 levels were observed and the immunostaining of the tumor for KL-6 was evident. We thus consider KL-6 to be a potential novel marker for peritoneal malignant mesothelioma with epithelioid type.

Abstract
A new cell line of human malignant peritoneal mesothelioma (MPM), TU-MM-1, was established and characterized. The cells showed polygonal morphology, grew in monolayers without contact inhibition and were arranged like a jigsaw puzzle. The chromosome numbers ranged from 41 to 44. A low rate of proliferation was observed and the doubling time was 67.9 h. Genomic DNA sequencing revealed that TU-MM-1 cells harbored missense mutations in APC, LATS2, BRCA1/2, and TP53, and mutation of a splice donor site in BAP1 and loss of CDKN2A gene. We observed the absence of BAP1 and p16(INK4a) proteins, underexpression of LATS2 protein, and overexpression of p53 protein in TU-MM-1 cells in western blot analysis. Heterotransplantation to nude mice produced tumors that had the characteristics of the original tumor. This cell line may be useful for studying biological properties and contribute to novel treatment strategies.

Abstract
Malignant pleural mesothelioma (MPM) is an aggressive, treatment-resistant, and generally fatal disease. A 68-year-old male who was diagnosed with MPM at another hospital came to our hospital with dyspnea. We advised him to take combination chemotherapy but he refused to take the treatment. That was because he had already received chemotherapy with supportive care at another hospital but his condition worsened. Thus, we recommended photodynamic therapy (PDT) to deal with the dyspnea and MPM. After PDT, the dyspnea improved and the patient then decided to take the combination chemotherapy. Our patient received chemotherapy using pemetrexed/cisplatin. Afterwards, he received a single PDT treatment and then later took chemotherapy using gemcitabine/cisplatin. The patient showed a survival time of 27 months, which is longer than median survival time in advanced MPM patients. Further research and clinical trials are needed to demonstrate any synergistic effect between the combination chemotherapy and PDT.

Abstract
Purpose To investigate the ability of leucovorin (LV) to abrogate dose-limiting toxicities of pralatrexate (PDX) while maintaining efficacy, in vivo. Methods H2052 mesothelioma cells were treated with the antifolates methotrexate (MTX), PDX and pemetrexed, with and without LV rescue 24 h later. Cell killing was evaluated 48 h later. Female nude mice bearing H2052 xenografts were treated with varying doses and schedules of the antifolate PDX and LV. Results In vitro, H2052 cells were more sensitive to PDX as compared to MTX and pemetrexed. Administration of LV 24 h after antifolate treatment reduced efficacy of antifolates MTX and pemetrexed, but not PDX. In vivo, LV was found to reduce toxicity of PDX at the maximum tolerated dose without sacrificing efficacy. Lethal doses of PDX were rescued by LV, and mice bearing the H2052 tumor demonstrated prolonged and enhanced tumor regression. Conclusions High-dose PDX with subsequent LV rescue may be a viable treatment strategy in mesothelioma and other cancers. The inclusion of LV rescue into new and existing PDX treatment protocols should be explored as a way to expand the tolerability and effectiveness of PDX in the clinic.
