软组织肉瘤(soft tissue sarcoma,STS)是一组高度异质性不常见的肿瘤,目前已经明确的STS亚型有50多种。成人最常见的STS依次为:多形性未分化肉瘤、脂肪肉瘤、平滑肌肉瘤、滑膜肉瘤及恶性神经鞘瘤等。儿童最常见的STS是横纹肌肉瘤。对于成人STS并没有可以被广泛接受的治疗规范。一些预后因素已经明确,包括肿瘤的病理分级、大小、部位及是否发生远处转移等。对于STS治疗的一些相关因素尚有争议,
Soft tissue sarcoma (STS) is a group of highly heterogeneous and uncommon tumors. There are more than 50 STS subtypes that have been identified so far. The most common adult STS were: pleomorphic undifferentiated sarcoma, liposarcoma, leiomyosarcoma, synovial sarcoma and malignant schwannoma and so on.

Some relevant factors for the treatment of STS is still controversial,
