To determine the number of Mohs micrographic surgery (MMS) stages per tumor taken by early- to mid-career Mohs surgeons and to assess other factors affecting number of stages.
Statistical analysis of MMS logs of 20 representative early- to mid-career surgeons.
There was no difference in stages when surgeons were divided into two categories based on whether they had more than 500 cases per year or more than 5 years of experience. Similarly, when surgeons were categorized according to geographic location, there was no difference in number of stages. Anatomic location was associated with the number of stages (analysis of variance, p<.001), with the greatest number of stages for nose (2.01) and ear (2.06) lesions and the fewest for neck (1.47), back and shoulder (1.47), and lower extremity (1.33) lesions. Basal cell carcinomas required 1.92 stages (median 2.00), compared with 1.66 (median 1.00) for squamous cell carcinoma (p<.001).
Early- and mid-career Mohs surgeons appear to remove tumors with similar numbers of stages regardless of their experience, case volume, or geographic location. Number of stages varies with anatomic location and tumor type. The authors have indicated no significant interest with commercial supporters.
确定早期至中期 Mohs 显微外科医师每例肿瘤所采用的 Mohs 显微外科手术（MMS）阶段数，并评估影响阶段数的其他因素。
对 20 名有代表性的早期至中期 Mohs 外科医生的 MMS 日志进行统计学分析。
根据每年的病例数是否超过 500 例或经验是否超过 5 年，将外科医生分为两类时，手术阶段数没有差异。同样，根据地理位置对医生进行分类时，手术阶段数也没有差异。解剖部位与手术阶段数有关（方差分析，p<.001），鼻子（2.01）和耳朵（2.06）病变的手术阶段数最多，而颈部（1.47）、背部和肩部（1.47）以及下肢（1.33）病变的手术阶段数最少。基底细胞癌需要 1.92 个阶段（中位数为 2.00），而鳞状细胞癌需要 1.66 个阶段（中位数为 1.00）（p<.001）。
早期至中期 Mohs 外科医生似乎无论经验、病例量或地理位置如何，都能以相似数量的阶段切除肿瘤。手术阶段数因解剖部位和肿瘤类型而异。作者表示与商业支持者没有重大利益关系。
