Surgical resection of lentigo maligna (LM) is complicated by noncontiguous, subclinical extension and actinic melanocytic hyperplasia in sun-damaged skin of older individuals.
We sought to determine the long-term effectiveness of imiquimod as primary or adjuvant therapy for LM.
Patients were retrospectively identified from January 1, 2003, to December 31, 2013, with LM, early/evolving LM, and LM melanoma who had used topical imiquimod 5% cream for either primary therapy after diagnostic biopsy, or adjuvant therapy after narrow-margin surgical resection or complete clinical but not histologic resection of LM. Follow-up occurred through December 31, 2014.
In all, 63 cases were identified in 61 patients, mean (SD) age 71.1 (12.4) years; 58 were analyzed for local recurrence. Imiquimod was used as primary therapy in 22 of 63 (34.9%) and adjuvant therapy in 41 of 63 (65.1%) for mean duration of 11.7 (range 2-60) weeks. Fifty cases (86.2%) demonstrated clinical clearance at mean (SD) follow-up of 42.1 (27.4) months: 72.7% primary and 94.4% adjuvant at 39.7 (23.9) and 43.1 (28.9) months, respectively.
Retrospective cohort study and lack of standardized imiquimod application are limitations.
Imiquimod cream appears to be a viable option for primary or adjuvant treatment of LM in older patients who are poor surgical candidates.
由于在老年日光损伤皮肤中存在非连续的、亚临床的扩展和光化性黑素细胞增生，手术切除交界痣（LM）较为复杂。
我们旨在确定咪喹莫特作为 LM 的初始或辅助治疗的长期有效性。
2003 年 1 月 1 日至 2013 年 12 月 31 日，我们对患有 LM、早期/进展期 LM 和 LM 黑色素瘤的患者进行了回顾性研究，这些患者在诊断性活检后使用咪喹莫特 5%乳膏进行初始治疗，或在窄切缘手术切除后或 LM 的完全临床但非组织学切除后进行辅助治疗。随访时间截止到 2014 年 12 月 31 日。
共在 61 例患者中识别出 63 例（61 例患者中有 63 例），平均（SD）年龄 71.1（12.4）岁；58 例进行了局部复发分析。咪喹莫特在 63 例中的 22 例（34.9%）中作为初始治疗，在 63 例中的 41 例（65.1%）中作为辅助治疗，平均持续时间为 11.7（范围 2-60）周。50 例（86.2%）在平均（SD）随访 42.1（27.4）个月时显示出临床清除：39.7（23.9）个月时初始治疗的 72.7%和辅助治疗的 94.4%，以及 43.1（28.9）个月时初始治疗的 72.7%和辅助治疗的 94.4%。
回顾性队列研究和缺乏标准化的咪喹莫特应用是局限性。
咪喹莫特乳膏似乎是老年患者 LM 的初始或辅助治疗的可行选择，这些患者不适合手术治疗。
