Histologic grade, size, and depth are well-known prognostic factors in soft tissue sarcomas (STS). Small (< 5 cm) and superficial STS generally have an excellent prognosis when treated with appropriate surgery. However, they are often misdiagnosed and mistreated. We reported that in midterm follow-up (5 to 7 years), patients with unplanned resections of tumors with positive margins who immediately underwent a reoperation with margin-widening re-resection and postoperative radiotherapy had survival comparable to that of patients who were initially treated correctly. In that article, we included STS larger than 5 cm, deep STS, and individuals with local recurrence. However, we wanted to evaluate the impact of unplanned resection on the survival of patients who had STS with the best prognosis, small and superficial STS, with two groups that were as homogeneous as possible.

接受计划外切除的小型浅表软组织肉瘤患者的长期生存率是否比最初接受肿瘤切除治疗的患者更差？

组织学分级、大小和深度是软组织肉瘤 (STS) 众所周知的预后因素。当采用适当的手术治疗时，小（< 5 cm）和浅表的 STS 通常预后良好。然而，他们经常被误诊和虐待。我们报道，在中期随访（5至7年）中，计划外切除切缘阳性肿瘤的患者立即接受扩大切缘再切除和术后放疗的再次手术，其生存率与最初接受治疗的患者相当正确。在那篇文章中，我们纳入了大于 5 厘米的 STS、深部 STS 和局部复发的个体。然而，我们想要评估计划外切除对预后最好的 STS 患者生存的影响，即小而浅表的 STS，两组尽可能同质。
