Soft-tissue sarcomas (STS) are usually sensitive to doxorubicine and/or ifosfamide. When tumors become refractory to these two drugs, chemotherapeutic options are limited. All the drugs tested generally yield occasional or negligible response, with response rates lower than 20% and a poor duration of response. No second-line chemotherapy have been clearly adopted. In vitro synergistic cytotoxicity has been reported with gemcitabine and docetaxel combination. Promising anti-tumor activity has been described with gemcitabine alone, docetaxel alone or these two drugs in combination These treatments were generally well tolerated. The best response have been observed in leiomyosarcomas. According to these results, gemcitabine and docetaxel combination might be of interest in STS. However, a phase III study is required to better evaluate the real advantage of this treatment.
软组织肉瘤(STS)通常对阿霉素和/或异环磷酰胺敏感。当肿瘤对这两种药物产生耐药性时,化疗选择就很有限。所有测试的药物通常只能产生偶尔或可忽略不计的反应,有效率低于20%,且反应持续时间较短。目前尚未明确采用二线化疗方案。据报道,吉西他滨和多西他赛联合使用具有体外协同细胞毒性。单独使用吉西他滨、单独使用多西他赛或这两种药物联合使用均已显示出有前景的抗肿瘤活性。这些治疗通常耐受性良好。在平滑肌肉瘤中观察到了最佳反应。根据这些结果,吉西他滨和多西他赛联合使用可能对STS有意义。然而,需要进行一项III期研究来更好地评估这种治疗的实际优势。
