目的探讨影响软组织肉瘤(STS)手术后复发的因素,进一步确定STS的切缘。方法分析在我院行扩大切除术后局部复发的25例STS患者,记录肿瘤复发时间、大小、深浅位置等。重点观察肿瘤术后复发的类型和解剖部位。结果肿瘤复发类型为单发,两处复发,多发(≥3处),中位复发时间为7个月。近侧复发率为18.9%(11/60),复发构成比为39.3%(11/28)。原位复发率21.7%(13/60),复发构成比为46.4%(13/28)。远侧复发率为8.3%(5/60),复发构成比为10.7%(5/28)。结论控制STS术后复发应扩大切除近侧范围及严格无瘤操作。
Objective To investigate the factors affecting the recurrence after soft tissue sarcoma (STS) and further determine the margin of STS. Methods We analyzed 25 patients with STS who had local recurrence after extended resection in our hospital. The time, size, depth, and location of tumor recurrence were recorded. Focus on the type and anatomical site of tumor recurrence after surgery. Results The type of tumor recurrence was single, with two recurrences and multiple occurrences (≥3 sites). The median recurrence time was 7 months. The rate of proximal recurrence was 18.9% (11/60), and the recurrence ratio was 39.3% (11/28). The recurrence rate in situ was 21.7% (13/60), and the recurrence ratio was 46.4% (13/28). The rate of distal recurrence was 8.3% (5/60), and the recurrence ratio was 10.7% (5/28). Conclusions Control of recurrence after STS should be extended to resect the proximal range and strict non-neoplastic operation.
