BACKGROUND:Optimal surgical management for melanoma of the head and neck remains controversial. OBJECTIVE:Assess outcomes for melanomas of the head and neck treated with Mohs micrographic surgery (MMS) versus wide local excision (WLE) from the National Cancer Database. METHODS:Head and neck melanoma data from the National Cancer Database from years 2004-2015 were analyzed. RESULTS:In total, 50,397 cases of head and neck melanoma were reviewed; 3510 (7%) were treated with MMS and 46,887 (93%) with WLE. After controlling for potential confounding variables, patients treated with MMS were more likely than patients treated with WLE to survive after 5 years (hazard ratio [HR] 1.181, 95% confidence interval [CI] 1.083-1.288; P < .001). Factors associated with a statistically significant survival disadvantage included male sex (HR 1.287, 95% CI 1.242-1.357; P = 0), tumor ulceration (HR 1.687, 95% CI 1.616-1.760; P = 0), and positive surgical margins (HR 1.395, 95% CI 1.306-1.490; P = 0). Patient survival was inversely proportional to tumor Breslow depth. LIMITATIONS:Database study, limited number of MMS treated melanomas. CONCLUSION:MMS is a valid treatment option for melanoma of the head and neck; National Cancer Database data suggests that MMS might confer a survival benefit over WLE.


背景: 头颈部黑色素瘤的最佳手术治疗仍存在争议。 目的: 评估来自国家癌症数据库的Mohs显微外科手术 (MMS) 与广泛局部切除术 (WLE) 治疗头颈部黑色素瘤的结局。 方法: 对来自 2004-2015 年国家癌症数据库的头颈部黑色素瘤数据进行分析。 结果: 共回顾了 50,397 例头颈部黑色素瘤,3510 例 (7%) 采用MMS治疗,46,887 例 (93%) 采用WLE治疗。在控制了潜在的混杂变量后,MMS治疗的患者比WLE治疗的患者在 5 年后更有可能存活 (风险比 [HR] 1.181,95% 置信区间 [CI] 1.083-1.288; P <.001)。与统计学显著生存劣势相关的因素包括男性 (HR 1.287,95% CI 1.242-1.357; P = 0),肿瘤溃疡 (HR 1.687,95% CI 1.616-1.760; P = 0) 和阳性手术切缘 (HR 1.395,95% CI 1.306-1.490; P = 0)。患者生存期与肿瘤Breslow深度成反比。 局限性: 数据库研究,MMS治疗的黑色素瘤数量有限。 结论: MMS是头颈部黑色素瘤的有效治疗选择; 国家癌症数据库数据表明,MMS可能比WLE带来生存获益。

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.
