METHODS: Between April 2015 and November 2023, a total of 230 Japanese cases with BCC which underwent surgical resection with 2-mm, 3-mm, or 5-mm margins were followed in our hospital. We conducted a retrospective review that focused on the recurrence rate and histopathological margins.
RESULTS: Recurrence was recorded if the follow-up time was longer than 3 months. One of the 198 cases (0.5%) developed a recurrence. The mean lateral and deep histopathological margins were 2,525.4 μm (30.8-14,034.6 μm) and 3,409 μm (199.9-16,523.6 μm), respectively. Recurrence rate was associated with tumor size and clinical tumor border. However, histopathological margin was not associated with recurrence rate, even when it was less than 1,000 μm.
CONCLUSIONS: A narrow histopathological margin is acceptable for surgical resection of BCC in Japanese patients.
方法:在2015年4月至2023年11月之间,共有230例日本BCC患者接受了2毫米的手术切除,3-mm,或5毫米的边缘在我们医院随访。我们进行了回顾性审查,重点是复发率和组织病理学边缘。
结果:如果随访时间超过3个月,则记录复发。198例中有1例(0.5%)复发。平均横向和深层组织病理学边缘为2,525.4μm(30.8-14,034.6μm)和3,409μm(199.9-16,523.6μm),分别。复发率与肿瘤大小和临床肿瘤边界有关。然而,组织病理学边缘与复发率无关,甚至当它小于1000μm时。
结论:对于日本患者BCC的手术切除,狭窄的组织病理学切缘是可以接受的。
