Malignant pleural mesothelioma; mesothelioma of the lining of the lungs, or pleura.
January 6th, 2009. The aberrant promoter methylation of BMP3b and BMP6 in malignant pleural mesotheliomas
0004). Our study indicated that BMP3b and BMP6 genes were suppressed by DNA methylation and methylation of BMP3b is significantly frequent in Japanese MPMs, suggesting its pathogenic role and the ethnic difference in MPMs.
January 2nd, 2009. Epigenetic Profiles Distinguish Pleural Mesothelioma from Normal Pleura and Predict Lung Asbestos Burden and Clinical Outcome
We have added to the growing body of evidence that cellular epigenetic dysregulation is a critical mode of action for asbestos in the induction of pleural mesothelioma. Importantly, these findings hold great promise for using epigenetic profiling in the diagnosis and prognosis of human cancers.
January 2nd, 2009. A new electrocautery pleural biopsy technique using an insulated-tip diathermic knife during semirigid pleuroscopy
Conclusions: Electrocautery biopsy using the IT knife during semirigid pleuroscopy has great potential for diagnosing smooth abnormal pleura which are difficult to biopsy with SFF.
December 23rd, 2008. Malignant mesothelioma
Compensation issues must also be considered. Life expectancy in malignant mesothelioma is poor, with a median survival of about one year following diagnosis.

December 20th, 2008. Vitamin D-mediated hypercalcemia and Cushing syndrome as manifestations of malignant pleural mesothelioma
Conclusion: These findings support the evidence for a paracrine role of vitamin D in the resistance of the human host to antigen.
December 19th, 2008. Gemcitabine combined with oxaliplatin in pretreated patients with malignant pleural mesothelioma: an observational study
Conclusion: Pemetrexed-pretreated patients with progressive MPM may benefit from a consecutive chemotherapy with oxaliplatin and gemcitabine without significant toxicity.
December 17th, 2008. An autopsy case of sarcomatoid malignant mesothelioma mimicking adenocarcinoma with sarcomatoid elements of lung
Therefore, immunohistochemical staining was performed; the findings revealed sarcomatoid malignant mesothelioma. In conclusion, we encountered a rare case of sarcomatoid malignant mesothelioma (stage IV).
December 17th, 2008. Simian virus 40 sequences in blood specimens from healthy individuals of Casale Monferrato, an industrial town with a history of asbestos pollution
Conclusions: SV40 sequences are present in blood samples of healthy donors from Casale Monferrato with a prevalence similar to that reported in previous investigations of healthy donors from asbestos-free areas. Altogether these data suggest that SV40 is circulating in the human population.
December 12th, 2008. Problems in mesothelioma diagnosis
This review identifies some of these problems and addresses the uses and limitations of immunohistochemistry in different situations. It includes a discussion of some of the less common variants of mesothelioma and other pleural-based tumours that enter into the differential diagnosis.
December 11th, 2008. Pleomorphic carcinoma of the lung expressing podoplanin and calretinin
The sarcomatoid component in four of the 11 cases (36%) was immunoreactive with podoplanin, and it was calretinin positive in nine of the 11 cases (82%). When making the differential diagnosis between PC and the sarcomatoid component of mesothelioma, care is required in diagnosing biopsy specimens of peripheral lung spindle-cell tumors that are positive for both podoplanin and calretinin.
December 9th, 2008. Expression of GATA-6 transcription factor in pleural malignant mesothelioma and metastatic pulmonary adenocarcinoma
Conclusion: Results suggest that GATA-6 plays a role in pleural malignancies, predicting longer survival in subgroups of MM.
December 2nd, 2008. Monitoring of Chemotherapy Response in Malignant Pleural Mesothelioma Using Fluorodeoxyglucose Positron Emission Tomography
The tumor lesion exhibited shrinkage on CT and a decrease in the standardized uptake value (SUV) max after the first course of chemotherapy, but exhibited size enlargement and an increase in SUV max after the second course of chemotherapy. These findings suggest that results of quantification of metabolic response by FDG-PET are related to the objective response as determined by CT in patients with MPM.

November 28th, 2008. Biomarkers for malignant pleural mesothelioma: current status
Future research efforts should focus on biomarkers predictive of the efficacy and toxicity of standard chemotherapy. Translational research should be systematically incorporated into the design of clinical trials assessing new targeted agents in MPM.
November 26th, 2008. Malignant pleural mesothelioma: biology and diagnosis
Despite sometimes a good sensitivity, other potential markers as osteopontin are of little interest for MPM diagnosis because of a low specificity. In conclusion, the present data do not justify the use of biology for MPM diagnosis in routine yet but rather suggest a need for a continuing evaluation of soluble mesothelin in clinical studies and the search for other potential tumor markers.
November 26th, 2008. Mesothelioma: treatment
There are few active cytotoxic drugs in this disease. Currently, based on two randomised trials, the most efficacious chemotherapy regimen consists in a combination of cisplatin and an antifolate agent, pemetrexed or raltitrexed.

November 21st, 2008. Compensator-based intensity-modulated radiation therapy for malignant pleural mesothelioma post extrapleural pneumonectomy
Not all linear accelerators can deliver large-field MLC-based IMRT, but most can deliver a maximum conformal field of 40 x 40 cm. It is possible and reasonable to deliver IMRT with compensators for fields this size with most conventional linear accelerators.
November 14th, 2008. Outcomes with first-line platinum-based combination chemotherapy for malignant pleural mesothelioma: a review of practice in British Columbia
No difference is seen combining platinum analogs with gemcitabine or pemetrexed. Platinum-based doublets might represent a therapeutic ceiling for cytotoxic chemotherapy in MPM.

November 11th, 2008. Role of viral induced vascular endothelial growth factor (VEGF) production in pleural effusion and malignant mesothelioma
To show the specific effect of viral receptors knockdown experiments with siRNA for TLR3, RIG-I and MDA5 were performed. This finding of viral induced mesothelial VEGF synthesis may indicate a novel link between viral infections and formation of pleural effusions and progression of malignant mesothelioma.
November 8th, 2008. Effective chemotherapy based on a chemosensitivity test for malignant pleural mesothelioma
Numerous chemotherapeutic agents have been tested in many clinical trials, but the response rate does not exceed 20% for most of the investigated regimens. Here we report a case of MPM in which the chemotherapy based on the chemosensitivity test was very effective on palliation with stable disease for a long time.
November 8th, 2008. Transudates in Malignancy: Still a Role for Pleural Fluid
Conclusions: Cytological examination of pleural fluid in patients with unexplained transudative effusion is essential to rule out malignant processes.
