The optimal surgical approach (wide local excision [WLE] vs Mohs micrographic surgery [MMS]) for treating Merkel cell carcinoma (MCC) is yet to be determined.
To compare survival outcomes in patients with early-stage MCC treated with MMS versus with WLE.
A retrospective review of all cases in the National Cancer Database (NCDB) of MCC of clinical stage I or II MCC treated with WLE or MMS was performed.
A total of 1795 cases of stage I or II MCC who underwent WLE (n = 1685) or MMS (n = 110) were identified. There was no difference in residual tumor on surgical margins between the 2 treatment groups (P = .588). On multivariate analysis, there was no difference in overall survival between the treatment modalities (adjusted hazard ratio, 1.02; 95% confidence interval, 0.72-1.45; P = .897). There was no difference in overall survival between the 2 groups on propensity score-matched analysis.
Disease-specific survival was not reported, as these data are not available in the National Cancer Database.
MMS appears to be as effective as WLE in treating early-stage MCC.
治疗 Merkel 细胞癌(MCC)的最佳手术方法(广泛局部切除术[WLE]与 Mohs 显微外科手术[MMS])尚未确定。
比较接受 MMS 与 WLE 治疗的早期 MCC 患者的生存结果。
对国家癌症数据库(NCDB)中所有 I 期或 II 期 MCC 患者的病例进行回顾性研究,这些患者接受 WLE 或 MMS 治疗。
共确定了 1795 例接受 WLE(n=1685)或 MMS(n=110)治疗的 I 期或 II 期 MCC 患者。2 种治疗组的手术切缘残留肿瘤无差异(P=0.588)。多因素分析显示,2 种治疗方法的总生存率无差异(调整后的危险比,1.02;95%置信区间,0.72-1.45;P=0.897)。倾向评分匹配分析显示,2 组的总生存率无差异。
由于国家癌症数据库中未提供这些数据,因此未报告疾病特异性生存率。
MMS 似乎与 WLE 一样有效治疗早期 MCC。
