Owing to its rarity, dermatofibrosarcoma protuberance (DFSP) is often inappropriately excised. After unplanned excision (UE), additional excision is commonly performed. We aimed to elucidate the effect of additional excision after UE.
We examined 306 patients with primary DFSP. We analyzed surgical outcomes in 291 patients who received planned excision (PE) or additional excision after UE.
Of 306 patients, 194 received PE and the remaining 112 received UE. Of 112 patients, 97 received additional excision after UE. Additional surgery due to complications was more frequent in patients with UE than in those with PE. The 5-year local recurrence-free rate in patients without additional excision after UE was significantly worse than that in those with additional excision after UE.
If UE is performed, we recommend additional excision for preventing local recurrence; however, the surgical wound should be carefully observed.
由于其罕见性,隆突性皮肤纤维肉瘤(DFSP)常被不当切除。在非计划性切除(UE)后,通常需要进行额外的切除。我们旨在阐明 UE 后额外切除的效果。
我们检查了 306 例原发性 DFSP 患者。我们分析了接受计划性切除(PE)或 UE 后额外切除的 291 例患者的手术结果。
306 例患者中,194 例接受了 PE,其余 112 例接受了 UE。在 112 例患者中,97 例在 UE 后接受了额外的切除。UE 患者比 PE 患者因并发症而进行额外手术的频率更高。UE 后未行额外切除的患者 5 年局部无复发生存率明显差于 UE 后行额外切除的患者。
如果进行 UE,我们建议行额外切除以预防局部复发;然而,应仔细观察手术伤口。
