Poorly differentiated synovial sarcoma: A case report
2001
Poorly differentiated synovial sarcoma is a rare soft tissue tumor. We studied a case arising in the pleural cavity of a young subject, characterised by the presence of spindle cell, small cell, and large epithelioid cell areas. We performed stains for mucosubstances and analysed the expression of cytokeratins 5/6, 7, 8, 18, 19, CEA, CD34, Ber-Ep4 and calretinin to characterize the phenotype of this neoplasm. We furthermore assessed immunohistochemically the presence of p53, Bcl-2, Bax and caspase 3, four apoptotic markers, to evaluate a relationship between apoptotic activity and the behaviour of this tumor. Our findings showed a strong presence of calretinin, p53 and Bcl-2 in all three ar…

Antiblastic drug combinations with ifosfamide: an update
2003
Ifosfamide is an alkylating agent that is widely used in the treatment of various neoplasms, such as sarcomas, lymphomas, pediatric malignancies, germ cell tumors, lung, breast and ovarian cancer. The clinical toxicity of ifosfamide depends on the dose and administration schedules. The pharmacologic features of this drug enable its combination with other antiblastic agents, such as vinorelbine, gemcitabine, paclitaxel and docetaxel. Moreover, the pharmacologic profile of ifosfamide allows the use of this antiblastic drug in patients who have previously failed many other treatments, and a large percentage of responses has already been obtained. There is some concern about the optimal schedul…
