Less common than epithelioid mesothelioma, only 7% to 20% of mesothelioma are sarcomatoid. Often called the “wild” type because of it’s unpredictable nature.
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.

October 3rd, 2007. Malignant mediastinal tumor with bone formation–mesothelioma or sarcoma?
However, the tumor grew rapidly and spread to the pleura, involved the heart, and the patient succumbed. This is to our knowledge the first report of a sarcomatous mesothelioma with bone formation from environmental exposure to mineral fibers.

August 10th, 2007. D2-40-positive solitary fibrous tumors of the pleura: diagnostic pitfall of biopsy specimen
Focal immunoreactivity to D2-40 was positive in three out of seven cases, including the first case. Care is required in diagnosing biopsy specimens of D2-40-positive pleural spindle-cell tumors, especially in making the differential diagnosis between SFTP and malignant mesothelioma.
August 7th, 2007. Influence of Radiotherapy Technique and Dose on Patterns of Failure for Mesothelioma Patients After Extrapleural Pneumonectomy
Conclusions: High-dose hemithoracic RT appears to limit in-field LF compared with MDRT. However, DF remains a significant challenge, with one-half of our patients experiencing DF.
June 2nd, 2007. A comparative evaluation of immunohistochemical markers for the differential diagnosis between malignant mesothelioma, non-small cell carcinoma involving the pleura, and benign reactive mesothelial cell proliferation
Conclusion: In diagnosing mesothelioma it is necessary to use a panel of immunohistochemical stains, which should contain antibodies to markers for adenocarcinoma and mesothelioma. Due to the high costs of such a study, a two-stage method is
May 18th, 2007. SYT-SSX fusion is absent in sarcomatoid mesothelioma allowing its distinction from synovial sarcoma of the pleura
Molecular analysis completed in two independent laboratories showed that sarcomatoid mesothelioma samples were negative for the t(X-18). This result confirms the usefulness of this analysis in differentiating sarcomatoid mesothelioma from synovial sarcoma.
April 27th, 2007. Lymphohistiocytoid Variant of Malignant Mesothelioma of the Pleura: A Series of 22 Cases
We suggest that it should be reclassified as an epithelioid variant because of its similar behavioural characteristics. There was no evidence of Epstein-Barr virus-related infection.
April 11th, 2007. A case of malignant pleural mesothelioma with elevation of G-CSF and CYFRA in the serum and pleural fluid
Although CYFRA elevation in the serum and/or the pleural effusion in MPM patients has been previously reported, it has not been reported in any of the 5 MPM patients reported to have G-CSF elevation. Therefore, this is the first reported case of G-CSF-producing MPM with CYFRA elevation in both serum and the pleural effusion.
March 16th, 2007. D2-40 and calretinin – a tissue microarray analysis of 341 malignant mesotheliomas with emphasis on sarcomatoid differentiation
66. These data indicate that a combination of calretinin and D2-40 will improve diagnostic accuracy for spindle cell lesions of the pleura, whereas almost all epithelioid mesotheliomas are identified by calretinin alone.
February 24th, 2007. Quantification of alternative mRNA species and identification of thioredoxin reductase 1 isoforms in human tumor cells
5, previously not identified in human cells, were detected by mass spectrometry. Our data show differential expression of TrxR1 mRNA forms in malignant mesothelioma of different phenotype, and investigation of alternative transcript variants of TrxR1 could be a valuable tool in the diagnostics and characterization of tumors.
February 20th, 2007. Malignant peritoneal mesothelioma. Our experienced with triple combined therapy: cytoreduction, intraperitoneal perioperative chemotherapy and hyperthermia
Conclusions: Radical oncologic cytoreductive surgery combined with intraperitoneal perioperative chemotherapy provides good results with prolonged survival in selected cases, although morbidity is high. Based in our experience, biphasic sarcomatous mesotheliomas should be excluded from

086) with a marginal significance, indicating that complete surgical resection of the tumor and perioperative adjuvant therapy could be effective treatment for MPM in Japan. Thus, the development of multimodality therapy including surgical treatment for this disease may be required to improve surgical results of MPM patients.

January 26th, 2007. Sarcomatoid pleural mesothelioma presenting as posterior mediastinal tumor with dysphagia
The patient died of multiple organ failure on the 1st postoperative day. We report extremely rare cases of sarcomatoid mesothelioma that appeared to be posterior mediastinal tumor before surgery, and discuss the difficulty of diagnosing sarcomatoid mesothelioma with atypical clinical manifestations.
December 26th, 2006. A phase II study of intrapleural immuno-chemotherapy, pleurectomy/decortication, radiotherapy, systemic chemotherapy and long-term sub-cutaneous IL-2 in stage II-III malignant pleural mesothelioma
Conclusions: The multimodality treatment we adopted for stage II-III MPM was feasible, well tolerated by most of the patients and produced a favourable outcome. New targeted therapies are awaited for further improvements in the treatment of this disease.

November 8th, 2006. An autopsy case of sarcomatoid malignant pleural mesothelioma
Differential diagnosis of sarcomatoid mesothelioma or rhabdomyosarcoma is made by immunohistochemical staining, but it is sometimes difficult. For the selection of the best treatment strategy for mesothelioma especially in the early stage, we should be aware of this difficulty.
