PML expression in soft tissue sarcoma: Prognostic and predictive value in alkylating agents/antracycline-based first line therapy

Soft tissue sarcomas are aggressive tumors representing <1% of all adult neoplasms. Aim of our study was to evaluate promyelocytic leukemia gene expression value as prognostic factor and as a factor predicting response to alkylating agents/antracycline-based first line therapy. One hundred eleven patients affected by locally advanced and metastatic soft tissue sarcoma were selected. PML expression was evaluated by immunohistochemical analysis in pathological samples and in the corresponding normal tissue from each case. PML immunohistochemical results were correlated with prognosis and with radiological response to alkylating agents/antracycline-based first line therapy. PML expression was …
