• Gender Differences in Outcomes of Patients With Mesothelioma. N. Alpert, M. van Gerwen, R. Flores, et al. 2020;43(11):792-797. PubMed · Publisher · Free full text

  Abstract

  Background: Mesothelioma is a rare and deadly form of cancer, linked to asbestos exposure. Although the United Kingdom has banned asbestos, the incidence rate remains high. Previous research has indicated that female individuals have better survival than male individuals, but this has never been examined in the United Kingdom.

  Materials And Methods: Pleural mesothelioma cases from 2005 to 2014 were extracted from the United Kingdom Lung Cancer Dataset. Multivariable logistic regression was used to assess the clinical and demographic factors associated with gender. A multivariable Cox proportional hazards model and propensity matching methods were used to assess gender differences in overall survival while accounting for potential confounders.

  Results: There were 8479 (87.8%) male and 1765 (17.2%) female individuals included in the analysis. Female individuals were significantly younger, with more epithelial histology than male individuals. Female individuals had significantly better overall survival (adjusted hazard ratio, 0.85, 95% confidence interval, 0.81-0.90). Results remained similar when stratifying by age and performance status, and when limiting to patients with epithelial histology.

  Conclusions: The study increases knowledge about gender differences in mesothelioma survival and is the first to directly examine this in the United Kingdom. It further disentangles the effects of age, histology, and health status. Increased estrogen may improve survival and could provide a potential target for future therapies.

• Trimodality Treatment of Malignant Pleural Mesothelioma: An Institutional Review. M. Kapeles, M.F. Gensheimer, D.A. Mart, et al. 2018;41(1):30-35. PubMed · Publisher

  Abstract

  Objective: Malignant pleural mesothelioma (MPM) is a deadly disease with varying treatment options. This study retrospectively describes treatment practices at the University of Washington Medical System from 1980 to 2011, and evaluates the impact of trimodality therapy and radiation (photon and neutron) on survival.

  Methods: A retrospective study was conducted on patients treated for MPM. Univariate and multivariate methods were utilized to evaluate potential factors associated with survival. Treatments received and baseline characteristics were included. Survival analysis of trimodality therapy was performed using a propensity score method to control for baseline characteristics.

  Results: Among 78 eligible patients, the median age at diagnosis was 59 years and the median survival was 13.7 months. On multivariate analysis, the significant predictors of improved survival were age, smoking history, location, and receipt of radiation therapy or chemotherapy. In the 48 patients receiving radiation therapy, the difference in survival between neutron therapy and non-neutron therapy patients was not statistically significant: hazard ratio, 1.20 (95% confidence interval, 0.68-2.13), P=0.52. Patients receiving trimodality therapy were more likely to have early-stage disease (60% vs. 30%) and epithelioid histology (86% vs. 58%). In a propensity score-weighted Cox proportional hazards model, trimodality therapy patients had improved overall survival, hazard ratio 0.45, P=0.004, median 14.6 versus 8.6 months.

  Conclusions: Trimodality therapy was significantly associated with prolonged survival in patients with MPM, even when adjusting for baseline patient factors. Radiation therapy was associated with improved survival, but the modality of radiation therapy used was not associated with outcome.

• Fast neutron radiotherapy in the treatment of malignant pleural mesothelioma. S.A. Patel, A.S. Kusano, A. Truong, et al. 2015;38(1):47-50. PubMed · Publisher

  Abstract

  Introduction: Malignant pleural mesothelioma (MPM) is a fatal disease lacking standardized treatment. We describe the use of fast neutron radiation therapy in MPM patients referred to the Department of Radiation Oncology at the University of Washington Medical Center.

  Materials And Methods: Retrospective chart review of MPM patients receiving neutron radiotherapy treatment from 1980 to 2012.

  Results: A total of 30 MPM patients received fast neutron radiotherapy as part of their treatment regimen. Median age at diagnosis was 59.6 years (range, 46.6 to 72.3 y). Eighteen patients received fast neutron radiotherapy as a component of trimodality treatment. Median overall survival was 20.3 months (range, 5.5 to 73.3 mo) with 1 patient censored at 34.8 months and all other patients with confirmed dates of death. One patient receiving radiotherapy alone as a palliative measure died during radiation treatment. One patient was unable to tolerate radiotherapy and stopped before completing prescribed treatment. On univariate analysis, Brigham Stage at presentation was a significant predictor of survival (P<0.01). No significant differences in survival were observed when comparing patients who received trimodality treatment compared to those who did not.

  Conclusions: Fast neutron radiotherapy may be utilized in the management of MPM patients. However, treatment with fast neutron radiotherapy did not significantly improvement outcome, even when used in a trimodality regimen.

• Prognostic significance of Ki67 expression in malignant peritoneal mesothelioma. K. Pillai, M.H. Pourgholami, T.C. Chua, et al. 2015;38(4):388-94. PubMed · Publisher

  Abstract

  Objectives: Although Ki67 measurement by immunohistochemistry has been widely used as a prognostic index in cancers, it has not been reported in malignant peritoneal mesothelioma (MPM). Hence, this study examines the prognostic significance of Ki67 in MPM.

  Methods: Specimens from 42 MPM patients were screened for Ki67 expression using immunohistochemistry. Ki67 expression was classified into 2 groups on the basis of expression (<25%=low; ≥25%=high) using standard methods. Using Kaplan-Meier survival analysis, the significance of Ki67 was assessed in different clinicopathologic categories.

  Results: High expression of Ki67 (≥25% by immunohistochemical evaluation) was correlated with poor survival in the overall group (P=0.001); male sex (P=0.001); female sex (P=0.001); epithelioid tumors (P=0.001): male epithelioid (P=0.001), female epithelioid (P=0.003); peritoneal cancer index (PCI): PCI<20 (P=0.001), PCI≥20 (P=0.002); and age at diagnosis (AAD): AAD<60 years (P=0.001), AAD≥60 years (P=0.004). Independent of Ki67, male sex (P=0.007), sarcomatoid histology (P=0.001), PCI≥20 (P=0.013), and AAD≥60 years (P=0.004) correlated with poor survival. Multivariate analysis showed that only AAD≥60 years (P=0.049) and high Ki67 expression for all tumors (P=0.031), male sex (P=0.038), female sex (P=0.021), epithelioid tumors (P=0.044), and AAD<60 years (P=0.029) were statistically significant.

  Conclusions: Ki67 expression affects prognosis in MPM patients and helps to predict survival within the various clinicopathologic categories.

• An open-label phase I pilot study of continuous intrapleural infusion of escalated doses of methotrexate in malignant pleural mesothelioma. M.M. Ellithy, N.S. El Baghdady, L.M. El Wakeel, et al. 2013;36(5):514-8. PubMed · Publisher

  Abstract

  Objectives: The aim of this study was to evaluate the toxicity from escalated methotrexate (MTX) doses infused intrapleural over 5 days and to determine pleural and systemic drug levels with this chemotherapeutic approach.

  Patients And Methods: Five patients with malignant pleural mesothelioma were treated with 3 cycles of intrapleural MTX infused through a pigtail catheter inserted in the pleural space. MTX levels were estimated in the pleural fluid and serum once daily throughout the treatment cycles. Fourteen days between cycles were calculated from the last day of the previous one. The total dose for each cycle was infused over 5 days with simultaneous intravenous calcium folinate. The total cycle dose for the first, second, and third cycles were: 300, 501, and 750.5 mg/m, respectively.

  Results: The mean serum MTX level was 1.72 µmole/L, whereas that of the pleural fluid was 503.224 µmole/L. The mean serum/pleural ratio was 0.00396, whereas the pleural/serum ratio was 396.21. No remarkable toxicity was observed in the 5 patients except for patient 1 who developed fluid leakage around the puncture site. Patient 2 developed grade I hepatotoxicity and both patients developed grade I pleuritic chest pain and dry irritative cough.

  Conclusions: This study demonstrates no grade II toxicity from 750.5 mg/m of MTX infused intrapleural over 5 days. This approach allows attaining MTX pleural levels that are 95 to 3000 times higher than systemic serum levels, with minimal toxicity. The results mandate performing this trial on a wider scale as a preliminary step for a formal phase II study.

• Expert opinions of the first italian consensus conference on the management of malignant pleural mesothelioma. C. Pinto, A. Ardizzoni, P.G. Betta, et al. 2011;34(1):99-109. Consensus statement PubMed · Publisher

  Abstract

  Malignant pleural mesothelioma (MPM) is a very important public health issue. A large amount of data indicates a relationship between mesothelioma and asbestos exposure. The incidence has both considerably and constantly increased over the past 2 decades in the industrialized countries and is expected to peak in 2010-2020. In Italy, a standardized-rate incidence in 2002 among men was 2.98 per 100,000 and 0.98 per 100,000 among women, with wide differences from one region to another. Stage diagnosis and definition may be difficult. Management of patients with MPM remains complex, so an optimal treatment strategy has not yet been clearly defined. The First Italian Consensus Conference on Malignant Pleural Mesothelioma was held Bologna (Italy) in May 20, 2008. The Consensus Conference was given the patronage of the Italian scientific societies AIOM, AIRO, AIPO, SIC, SICO, SICT, SIAPEC-IAP, AIOT, GOAM, and GIME. This Consensus did not answer all of the unresolved questions in MPM management, but the Expert Opinions have nonetheless provided recommendations, presented in this report, on MPM management for clinicians and patients.

• Phase II study of gemcitabine plus docetaxel as second-line treatment in malignant pleural mesothelioma: a single institution study. I. Tourkantonis, N. Makrilia, M. Ralli, et al. 2011;34(1):38-42. PubMed · Publisher

  Abstract

  Objective: The combinations of cisplatin-pemetrexed and cisplatin-gemcitabine are considered the standard systemic therapy for malignant pleural mesothelioma (MPM), which is a rapidly progressive tumor. The purpose of the present study is to evaluate the efficacy, safety, and clinical benefit of the gemcitabine plus docetaxel regimen in the second-line treatment of this disease.

  Patients And Methods: A total of 37 patients with MPM were treated with the combination of docetaxel (80 mg/m) and gemcitabine (1000 mg/m) on day 1 and 14 of a 28-day cycle. The regimen was repeated for a maximum of 6 cycles or until disease progression or unacceptable toxicity.

  Results: There was partial response of the disease in 7 patients (18.9%), whereas it remained stable in 23 patients (62.2%) and progressed in 7 patients (18.9%). The median time to disease progression was 7 months (range: 5.8-8.2 months) with a mean survival of 16.2 months (range: 13-19.3 months).

  Conclusion: The biweekly administration of docetaxel and gemcitabine, along with granulocyte colony-stimulating factor support, constitutes a safe, tolerable, and convenient regimen for the treatment of MPM, suggesting that this combination may be a viable option, especially in previously treated patients.

• An association between postoperative radiotherapy for primary breast cancer in 11 National Surgical Adjuvant Breast and Bowel Project (NSABP) studies and the subsequent appearance of pleural mesothelioma. M. Deutsch, S.R. Land, M. Begovic, et al. 2007;30(3):294-6. PubMed · Publisher

  Abstract

  Objectives: Among the minority of patients with pleural mesothelioma and no known exposure to asbestos, there have been case reports suggesting a possible association with previous radiotherapy. The association between radiotherapy for primary breast cancer and the subsequent occurrence of mesothelioma was investigated in women entered into 11 National Surgical Adjuvant Breast and Bowel Project (NSABP) prospective clinical trials for breast cancer.

  Methods: Follow-up information was obtained on 22,140 patients entered into 11 NSABP clinical trials for treatment of primary breast cancer between 1971 and 1994. Postoperative radiotherapy was administered to 9342 patients, mainly after lumpectomy. Postlumpectomy patients were treated with radiotherapy just to the ipsilateral breast and without regional nodal irradiation. There were 12,798 patients who did not have postoperative radiotherapy, and almost all had mastectomy.

  Results: Three pleural mesotheliomas were identified, and all occurred in the ipsilateral thorax of the irradiated patients (P = 0.009). All had received postlumpectomy breast irradiation for ductal carcinoma in situ. None had a known previous exposure to asbestos.

  Conclusions: There appears to be a small but statistically significant increased risk of developing mesothelioma following radiotherapy administered for primary breast cancer. However, in absolute numbers, the risk is too small to be considered a contraindication to administering radiotherapy when indicated.

• Combination chemotherapy with mitoxantrone, methotrexate, and mitomycin (MMM regimen) in malignant pleural mesothelioma: a phase II study. C. Pinto, A. Marino, M. Guaraldi, et al. 2001;24(2):143-7. PubMed · Publisher

  Abstract

  The prognosis of malignant pleural mesothelioma is poor, with a median survival time from diagnosis of 7 to 17 months. At present there is no standardized treatment of this neoplasia. Between July 1995 and January 1999, 22 patients with malignant pleural mesothelioma were enrolled in our study. The characteristics of patients were: 16 men and 6 women; median age 61 years (range, 49-77 years); stage (according to Butchart): 8 patients stage I, 10 stage II, 2 stage III, and 2 stage IV; cytologic diagnosis in 5 cases and histologic diagnosis in 17 cases. The treatment consisted of mitoxantrone 10 mg/m2 intravenous (IV) or intrapleural (IPL), methotrexate 35 mg/m2 IV, and mitomycin 7 mg/m2 IV on day 1 and repeated every 3 weeks, with mitomycin in alternate cycles (MMM regimen). One complete response (4.5%) (42 months of duration) and 6 partial responses (27.3%) (5, 5, 7, 9, 14, and 19 months of duration) were achieved; the overall response rate (ORR) was 31.8% (95% CI, 12.4-51.3%); 7 patients were stable under this treatment (31.8%). According to the pathologic type, ORR for the only epithelial type was 39.9% (95% CI, 15.2-64.8%). Median time to progression was 6 months (range, 1-22). The overall median survival time was 13.5 months (range, 1-50); the median survival time of responders significantly differed from that of nonresponders (18.0 versus 8.5 months; p = 0.017). This treatment produced a considerable clinical benefit, with improvement of dyspnea (68.4%) and pain (33.3%); 15 of 19 patients (78.9%) with pleural effusion at the time of diagnosis showed an important reduction in pleural fluid during chemotherapy. Hematologic toxicity was the main side effect; World Health Organization grade III to IV of neutropenia, anemia, and thrombocytopenia were observed in 81.8%, 13.6%, and 22.7% of patients, respectively. From the data presented here, this regimen can be considered active in the treatment of malignant pleural mesothelioma.

• Malignant peritoneal mesothelioma after Thorotrast exposure. C. Stey, U. Landolt-Weber, W. Vetter, et al. 1995;18(4):313-7. Case report PubMed · Publisher

  Abstract

  A case of a malignant peritoneal mesothelioma in a 63-year-old male patient with a history of exposure to Thorotrast in 1945 is presented. There was no history of exposure to asbestos. The clinical manifestation was a serosal effusion, which required weekly ascites puncture until therapy with intraperitoneal bleomycin was initiated. The latter treatment led to a significant reduction of ascites without any influence on tumor progression. Unfortunately, intraperitoneal bleomycin was accompanied by pulmonary toxicity, but at a higher total dose than known for intravenous administration. Three years after diagnosis the patient is still alive, without relapse of ascites production after bleomycin had to be stopped. Considering the risk of pulmonary fibrosis with high-dose intraperitoneal bleomycin and the lack of efficacy on tumor reduction, bleomycin seems to offer no advantage with respect to cisplatin.

• Brain metastases in malignant pleural mesothelioma. Case report and review of the literature. K.S. Sridhar, A.M. Hussein, P. Ganjei, et al. 1989;12(3):222-8. Case report · Review PubMed · Publisher

  Abstract

  Recent advances in pleural malignant mesothelioma include the sequential use of palliative surgery, perioperative radiation therapy, and systemic chemotherapy. Radical treatments may not only palliate but also improve survival in some patients. The latter may be associated with the appearance of metastases in unusual sites including the central nervous system. In malignant mesothelioma, brain metastases were previously reported in 19 patients at autopsy and in only 1 patient antemortem. We detail the clinical presentation in the second patient with pleural malignant mesothelioma thus far reported to develop brain metastases. The difficulties in diagnosis, the role of immunoperoxidase stains in malignant mesothelioma, excellent tolerance of different modalities of treatment, and a review of the literature of brain metastases in mesothelioma are discussed. Based on our report, the possibility of brain metastases should be investigated by careful clinical examination prior to a radical treatment in patients with progressive refractory mesothelioma.

• Chemotherapy for malignant mesothelioma; CAMEO. J.R. Jett, R.T. Eagan. 1982;5(4):429-31. PubMed · Publisher

  Abstract

  Twelve patients with a tissue diagnosis of malignant mesothelioma were treated with combination chemotherapy (CAMEO) every 4-5 weeks, with or without hemithoracic radiation. Mean survival from the time of tissue diagnosis an start of protocol treatment was 15.7 and 12.6 months, respectively. Median survival from the time of tissue diagnosis and start of protocol treatment was 11 and 6.5 months, respectively. Two patients were long-term survivors (32 and 45 months), one of whom is alive without evidence of recurrent disease. Toxicity from this regimen was moderate.
