OBJECTIVE:To evaluate the long-term outcomes of sentinel lymph node biopsy (SLNB) for head and neck cutaneous melanoma (HNCM). STUDY DESIGN:Retrospective cohort study. SETTING:Tertiary academic medical center. SUBJECTS AND METHODS:Longitudinal review of a 356-patient cohort with HNCM undergoing SLNB from 1997 to 2007. RESULTS:Descriptive characteristics included the following: age, 53.5 ± 19 years (mean ± SD); sex, 26.8% female; median follow-up, 4.9 years; and Breslow depth, 2.52 ± 1.87 mm. Overall, 75 (21.1%) patients had a positive SLNB. Among patients undergoing completion lymph node dissection following positive SLNB, 20 (27.4%) had at least 1 additional positive nonsentinel lymph node. Eighteen patients with local control and negative SLNB developed regional disease, indicating a false omission rate of 6.4%, including 10 recurrences in previously unsampled basins. Ten-year overall survival (OS) and melanoma-specific survival (MSS) were significantly greater in the negative sentinel lymph node (SLN) cohort (OS, 61% [95% CI, 0.549-0.677]; MSS, 81.9% [95% CI, 0.769-0.873]) than the positive SLN cohort (OS, 31% [95% CI, 0.162-0.677]; MSS, 60.3% [95% CI, 0.464-0.785]) and positive SLN/positive nonsentinel lymph node cohort (OS, 8.4% [95% CI, 0.015-0.474]; MSS, 9.6% [95% CI, 0.017-0.536]). OS was significantly associated with SLN positivity (hazard ratio [HR], 2.39; P < .01), immunosuppression (HR, 2.37; P < .01), angiolymphatic invasion (HR, 1.91; P < .01), and ulceration (HR, 1.86; P < .01). SLN positivity (HR, 3.13; P < .01), angiolymphatic invasion (HR, 3.19; P < .01), and number of mitoses (P = .0002) were significantly associated with MSS. Immunosuppression (HR, 3.01; P < .01) and SLN status (HR, 2.84; P < .01) were associated with recurrence-free survival, and immunosuppression was the only factor significantly associated with regional recurrence (HR, 6.59; P < .01). CONCLUSIONS:Long-term follow up indicates that SLNB showcases durable accuracy, safety, and prognostic importance for cutaneous HNCM.


目的: 评价前哨淋巴结活检 (SLNB) 治疗头颈部皮肤黑色素瘤 (HNCM) 的长期疗效。 研究设计: 回顾性队列研究。 单位: 三级学术医学中心。 对象和方法: 对 1997 年至 2007 年接受SLNB的 356 例HNCM患者队列进行纵向回顾。 结果: 描述性特征包括: 年龄,53.5 ± 19 岁 (平均 ± SD); 性别,26.8% 为女性; 中位随访时间,4.9 年; Breslow深度,2.52 ± 1.87毫米。总体而言,75 例 (21.1%) 患者SLNB阳性。在SLNB阳性后接受完整淋巴结清扫的患者中,20 例 (27.4%) 至少有 1 例额外的非前哨淋巴结阳性。18 例局部对照、SLNB阴性的患者发生区域疾病,假漏检率为 6.4%,其中既往未取样盆地复发 10 例。阴性前哨淋巴结 (SLN) 队列的十年总生存率 (OS) 和黑色素瘤特异性生存率 (MSS) 显著更高 (OS,61% [95% CI,0.549-0.677]; MSS,81.9% [95% CI,0.769-0.873] 比阳性SLN队列 (OS,31% [95% CI,0.162-0.677];MSS,60.3% [95% CI,0.464-0.785]) 和阳性SLN/阳性非前哨淋巴结队列 (OS,8.4% [95% CI,0.015-0.474]; MSS,9.6% [95% CI,0.017-0.536])。OS与SLN阳性 (风险比 [HR],2.39; P < .01) 、免疫抑制 (HR,2.37; P < .01) 、血管淋巴侵犯 (HR,1.91; P < .01) 和溃疡 (HR,1.86; P <.01)。SLN阳性 (HR,3.13; P < .01) 、血管淋巴侵犯 (HR,3.19; P < .01) 和核分裂数目 (P = .0002) 与MSS显著相关。免疫抑制 (HR,3.01; P < .01) 和SLN状态 (HR,2.84; P < .01) 与无复发生存期相关,免疫抑制是唯一与区域复发显著相关的因素 (HR,6.59; P <.01)。 结论: 长期随访表明SLNB显示了皮肤HNCM的持久准确性、安全性和预后重要性。

METHODS::Blue rubber bleb naevus syndrome (BRBNS) is an extremely rare venous malformation that often manifests as multiple haemangioma-like lesions in the skin and gastrointestinal tract. The drug sirolimus plays a key role in the signalling pathway of angiogenesis and subsequent development of BRBNS and its use has been described in several case reports. We present a case series of four patients with BRBNS who exhibited good treatment response to sirolimus. All four patients were administered oral sirolimus at doses of 1.0-1.5 mg/m2 /day with a target drug level of 5-10 ng/mL and median treatment duration of 20 months. All patients had a reduction in the size of the lesions and a normalization of coagulopathy with tolerable drug adverse reactions at follow-up. Sirolimus may be effective and safe in paediatric patients with BRBNS. Further prospective studies are suggested to evaluate the long-term effectiveness of this drug.

METHODS:BACKGROUND:Human papillomavirus (HPV) infections are associated with common dermatologic and nondermatologic diseases. Although HPV vaccines are well established as preventive measures for genital warts and cervical neoplasia, their use as therapeutic agents deserves greater attention. OBJECTIVE:To evaluate the use of HPV vaccine(s) as a treatment modality for cutaneous and/or mucosal disease. METHODS:A primary literature search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted in January 2019 by using the PubMed and Cochrane databases. RESULTS:A total of 63 articles with 4439 patients were included. The majority of patients with cutaneous warts, recurrent respiratory papillomatosis, and squamous and basal cell carcinomas were successfully treated with HPV vaccination. Preliminary data on patients with pre-existing anogenital warts, cervical intraepithelial neoplasia, anal intraepithelial neoplasia, and vulvar intraepithelial neoplasia is promising. LIMITATIONS:This review was limited by the lack of controls, patients' previous HPV vaccination status, and publication bias. CONCLUSION:The commercially available three-dose, quadrivalent HPV vaccine is a potential therapeutic option for the treatment of cutaneous warts, recurrent respiratory papillomatosis, and squamous and basal cell carcinomas. Noncommercially available HPV vaccines demonstrate therapeutic response for treating anogenital warts, cervical intraepithelial neoplasia, anal intraepithelial neoplasia, and vulvar intraepithelial neoplasia. The vaccine's efficacy as an adjunct therapy for HPV-associated cutaneous and/or mucosal disease warrants further exploration.

METHODS::Our understanding of melanoma precursors and progression to melanoma has developed as a result of advances in the field of molecular diagnostics. We now better understand the potential for genetic heterogeneity within a single lesion. Combined tumors can pose a diagnostic challenge when deciding the line between benign and malignant, which in turn has direct implications for patient management. Primary cilia (PC) are ubiquitous sensory organelles that have essential functions in cellular proliferation, differentiation, and development. The ciliation index (percentage of ciliated melanocytes) has been shown to reliably differentiate melanoma, which fail to ciliate, from melanocytic nevi, which retain PC. We therefore analyzed the potential for using the ciliation index to differentiate benign and malignant components in combined melanocytic lesions. We collected patient samples (n = 10) of unequivocal combined lesions with both melanoma and associated nevus components. Melanocytes were highlighted with SOX10 and costained with gamma-Tubulin and acetylated alpha-Tubulin to highlight the basal body and cilium, respectively. The number of melanocytes retaining cilia under high-power microscopy was examined. The melanoma component had average of 4% ciliation (SD: 7%), whereas the associated nevus component was significantly higher with 59% ciliation (SD: 17%). These data show that PC may be a reliable means of distinguishing benign from malignant components within a single tumor. The ciliation index may be a helpful tool in distinguishing challenging cases of combined lesions of melanoma in situ with a dermal nevus component from invasive melanoma, thus promoting improved staging and clinical management.
