This systematic review was conducted following PRISMA guidelines. The PubMed, Embase, and Scopus databases were searched. Our study was registered in PROSPERO (ID: 415624). Quality appraisal was done using STROBE guidelines.
A total of 7 studies and 123 patients were included. Metastasis was the only risk factor for disease-specific death (OR = 107.85, P< .001). Previous unplanned excision (OR = 22.29, P = .009) and positive margins (OR = 64.48, P = .011) were associated with higher risk of local recurrence. Patients with high-grade tumors (OR = 13.22, P = .023) and tumors ≥6 cm (OR = 7.40, P = .022) were more likely to develop metastases. After adjusting for confounders (age, sex, and presence of metastasis), amputation was not associated with poorer disease-specific survival.
Metastasis was the single most important risk factor for death with foot and ankle soft tissue sarcoma. Positive margins and history of previous unplanned excision are risk factors for local recurrence. The most important risk factors for metastasis are tumor grade and size ≥6 cm. Amputation was not associated with poorer disease-specific survival.

■共纳入7项研究和123例患者。转移是疾病特异性死亡的唯一危险因素(OR=107.85,P<.001)。先前的非计划切除(OR=22.29,P=.009)和阳性切缘(OR=64.48,P=.011)与较高的局部复发风险相关。高级别肿瘤(OR=13.22,P=.023)和肿瘤≥6cm(OR=7.40,P=.022)患者更容易发生转移。在调整了混杂因素(年龄,性别,和转移的存在),截肢与较差的疾病特异性生存率无关.
■转移是导致足踝部软组织肉瘤死亡的最重要的危险因素。切缘阳性和既往非计划切除史是局部复发的危险因素。转移最重要的危险因素是肿瘤分级和大小≥6cm。截肢与较差的疾病特异性生存率无关。
