Journal Articles on Mesothelioma: 'Sarcomatoid' Category
Less common than epithelioid mesothelioma, only 7% to 20% of mesothelioma are sarcomatoid. Often called the “wild” type because of it’s unpredictable nature.
August 14th, 2008. Soft tissue sarcoma metastatic to pleura
It is very difficult to distinguish them form sarcomatous malignant mesothelioma on histopathological features. We report a 57 year-old man who presented to us with left chest pain and progressive dyspnea and was diagnosed to have a pleural metastases of soft tissue sarcoma by thoracoscopic biopsy.
July 29th, 2008. Malignant Mesothelioma—A Connective Tissue Tumor with Proteoglycan-Dependent Differentiation
The differentiation as well as much of the malignant nature of these tumors is dependent on the expression of surface PGs. The syndecans, however, also translocate to the nucleus for an as yet unknown function.
July 1st, 2008. Morbidity, mortality, mean survival, and the impact of histology on survival after pleurectomy in 64 patients with malignant pleural mesothelioma
Conclusion: Our results show that pleurectomy can be performed as a means of palliation for advanced-stage disease with a low mortality rate and may, in fact, improve survival in patients with epithelial subtype as compared with historical controls in the literature with no surgical intervention.

July 1st, 2008. Malignant mesothelioma with heterologous elements: clinicopathological correlation of 27 cases and literature review
Immunohistochemical labelling for cytokeratins is helpful in the distinction, but lack of labelling for cytokeratins in a spindle cell/sarcomatoid tumour does not exclude the diagnosis of mesothelioma, irrespective of the presence of heterologous elements. We suggest that if the anatomical distribution conforms to that of mesothelioma, a diagnosis of heterologous mesothelioma should be made in preference to a diagnosis of primary pleural osteosarcoma or chondrosarcoma, regardless of cytokeratin positivity, as for conventional non-heterologous sarcomatoid mesothelioma.

June 4th, 2008. Pulmonary Paragonimiasis with Coincidental Malignant Mesothelioma
Here, we report a very rare case of malignant mesothelioma with a concomitant infection of parasitic lung fluke. Keywords: paragonimiasis, malignant mesothelioma, eosinophilia.
May 23rd, 2008. Primary peritoneal mesotheliomas in children: a clinicopathological and immunohistochemical study of eight cases
Conclusions: Peritoneal malignant mesothelioma in children is a rare condition that can introduce difficulties in histopathological diagnosis.

May 2nd, 2008. Trimodality Treatment of Malignant Pleural Mesothelioma
Conclusions: Trimodality treatment in malignant pleural mesothelioma seems to prolong survival in patients without lymph node metastasis. Novel techniques are needed for preoperative assessment of extrapleural lymph nodes.

April 30th, 2008. The value of occult disease in resection margin and lymph node after extrapleural pneumonectomy for malignant mesothelioma
Conclusions: In malignant pleural mesothelioma, the presence of occult disease in resection margins and lymph nodes can be identified by immunohistochemistry and significantly influences the prognosis. Cervical mediastinoscopy is useful in all patients considered for radical resection, but all specimens should be processed with immunohistochemical staining.

April 9th, 2008. Epidermal growth factor receptor gene mutation, amplification and protein expression in malignant pleural mesothelioma
In MPM, EGFR seems to play a role in a limited subset of patients. To identify possible candidates for EGFR tyrosine kinase in inhibitor therapy, the information on the EGFR gene status may be valuable.

April 4th, 2008. Establishment of three novel human malignant pleural mesothelioma cell lines: morphological and cytogenetical studies and EGFR mutation status
Conclusion: FACS analysis is more sensitive for evaluating mesothelin expression than immunohistochemistry of cut specimens. Irrespective of the expression of EGFR on FACS analysis, no EGFR mutation was detected. These three cell lines may be useful for studying cellular, molecular and genetic aspects of mesothelioma.
March 25th, 2008. Malignant pleural mesothelioma: Computed tomography and correlation with histology
Conclusions: Ipsilateral volume loss is most frequently associated with sarcomatous or mixed mesothelioma. The remaining imaging findings are not helpful in predicting the histological subtype of malignant mesothelioma.

March 6th, 2008. Application of Immunohistochemistry to the Diagnosis of Malignant Mesothelioma
Conclusions: Various antibody panels have been recommended for the diagnosis of MM, with no overall consensus about how many and which markers should be used. A recent study with Bayesian statistics has demonstrated that the use of many markers does not provide higher diagnostic accuracy than the use of selected single antibodies or various combinations of only 2 markers. There is a need for the development of evidence-based or consensus-based guidelines for the diagnosis of MM in different differential diagnosis situations.
March 6th, 2008. Targeted drug delivery to mesothelioma cells using functionally selected internalizing human single-chain antibodies
We have further exploited the internalizing function of these scFvs to achieve targeted intracellular drug delivery to mesothelioma cells. We showed that scFv-targeted immunoliposomes were efficiently and specifically taken up by both epithelioid and sarcomatous mesothelioma cells, but not control cells, and immunoliposomes encapsulating the small-molecule drug topotecan caused targeted killing of both types of mesothelioma cells in vitro.
February 29th, 2008. Local recurrence of tumor at sites of intervention in malignant pleural mesothelioma
LD was not associated with the stage of the disease. The most suitable candidate groups for PR are patients receiving supportive therapy, thoracotomy without multi-modal therapy or patients with sarcomatous and mixed cell type tumors.

February 19th, 2008. Malignant pleural mesothelioma: multidisciplinary experience in a public tertiary hospital
Conclusions: In the cases studied, an integrated multidisciplinary approach was used, and a highly complex hospital infrastructure was available for the diagnosis and treatment of MPM, as recommended in the literature. However, the mean survival was only 11 months, reflecting the aggressiveness of the disease.

January 18th, 2008. Differential diagnosis of sarcomatoid mesothelioma from true sarcoma and sarcomatoid carcinoma using immunohistochemistry
2, WT1, and AE1/AE3 is recommended for routine pathological diagnosis. Accurate clinical information is necessary for differentiating sarcomatoid mesothelioma from sarcomatoid carcinoma.
December 29th, 2007. Podoplanin is a Better Immunohistochemical Marker for Sarcomatoid Mesothelioma Than Calretinin
Overall sensitivities and pecificities were 84% and 99% for antipodoplanin, and 86% and 96% for D2-40. These findings suggest that cytoplasmic podoplanin expression may be useful in the diagnosis of sarcomatoid mesothelioma, although it should be used with caution on biopsy material.
December 25th, 2007. Localised malignant pleural mesothelioma: a separate clinical entity requiring aggressive local surgery
Conclusion: Our results suggest that surgery is indicated in treating localised MPM even in T4 (diffuse chest wall involvement) tumours but pleuropneumonectomy is not necessary. These tumours seem to have a different biological behaviour compared to diffuse MPM but further research, including identification of possibly different biological markers is necessary.

November 3rd, 2007. Flowcytometric immunophenotyping of peripheral-blood leukocytes in relation to immunopathology and cellular proliferation of pleural mesothelioma
In conclusion, mesothelioma might be associated with modulation of the tumoricidal effect of cytotoxic T lymphocytes in relation to tumor differentiation and its proliferative potentiality. Immunophenotyping analysis of leukocytes may reflect the competence of immune system against malignancy and act as an additive prognostic parameter for mesothelioma progression and probably expecting response to oncotherapy protocols.
November 3rd, 2007. Novel expression of kallikreins, kallikrein-related peptidases and kinin receptors in human pleural mesothelioma
KRP/hK2, 6, 8 and 9 were also expressed in the cytoplasm and nuclei of mesothelioma cells, whereas KRP/hK5 and hK7 showed predominantly cytoplasmic localisation. This is a first report, but further studies are required to determine whether these proteins have a functional role in the pathogenesis of mesothelioma and/or may be potential biomarkers for pleural mesothelioma.
