很少有研究表明皮肤外科医生如何处理部位识别问题。当肿瘤的解剖位置有问题时，估计手术治疗皮肤癌的频率和特征。全国性、前瞻性、多部位队列研究。在 22 个国家的 17,076 例病例中中心，98 (0.60%) 是有问题的病变 (LIQ)，其部位识别最初不确定，这些病变更常见于男性、老年且在 30 多天前进行活检的患者。外科医生平均采用 5.0 (95% CI: 4.61-5.39) 种额外技术来确认部位位置，常见方法包括： 重新检查可用文档（90 个病变，92%）；进行扩大体检（89 个病变，91%）；并要求患者用镜子指向（61 个病变，62%）。 15% 的患者需要向活检提供者索取照片，另外 15% 的患者需要获得冰冻切片活检。 10% 的患者已联系转诊医生。最终，外科医生成功地确定了 82% (80/98) 最初不确定的部位，其余 18% (18/98) 被推迟。大多数推迟的手术都发生在非面部部位。地点是学术中心。当肿瘤的解剖位置不确定时，皮肤外科医生会使用多种方法来确定部位，有时病例会被推迟。版权所有 © 2024。由 Elsevier Inc. 出版。

Few studies show how dermatologic surgeons manage problems with site identification.To estimate frequency and characterize management of skin cancer treated by surgery when the anatomic location of the tumor is in question.Nationwide, prospective, multi-site cohort study.Among 17,076 cases at 22 centers, 98 (0.60%) were lesions in question (LIQ) for which site identification was initially uncertain, with these more often in patients who were male, older, and biopsied more than 30 days ago. Surgeons employed on average 5.0 (95% CI: 4.61-5.39) additional techniques to confirm the site location, with common approaches including: re-checking available documentation (90 lesions, 92%); performing an expanded physical examination (89 lesions, 91%); and asking the patient to point using a mirror (61 lesions, 62%). In 15%, photographs were requested from the biopsying provider, and also in 15%, frozen section biopsies were obtained. In 10%, the referring physician was contacted. Eventually, surgeons succeeded in definitively identifying 82% (80/98) of initially uncertain sites, with the remaining 18% (18/98) postponed. Most postponed surgeries were at non-facial sites.Sites were academic centers.When the anatomic location of the tumor is uncertain, dermatologic surgeons use multiple methods to identify the site, and sometimes cases are postponed.Copyright © 2024.
