PURPOSE:Treatment package time (TPT) prolongation is associated with lower overall survival and locoregional control in mucosal head and neck squamous cell carcinoma (SCC), but there are few reports in cutaneous HNSCC (cHNSCC). We sought to test the effect of TPT in a cohort of patients with cHNSCC. METHODS:This is a single institution retrospective study of node-positive cHNSCC patients involving either the parotid or cervical nodes treated with curative intent surgery with macroscopic tumor clearance followed by standard fractionation postoperative radiation therapy (PORT) from 2001 to 2014. We assessed the effect of TPT and other prognostic variables on overall survival (OS), cHNSCC specific survival (CSS) progression free survival (PFS), and freedom from locoregional failure (FFLRF). RESULTS:In the present study, 152 patients met the inclusion criteria. The 5-year OS, CSS, PFS, and FFLRF were 62% (95% confidence interval [CI], 54-71), 78% (95% CI, 71-87), 54% (95% CI, 46-64), and 76% (95% CI ,68-85), respectively. In a multivariable model, TPT ≥14 weeks was associated with worse outcomes in all endpoints (OS [hazard ratio (HR) 4.93; 95% CI, 2.54-9.56, P < .001], CSS [HR 6.09; 95% CI, 2.33-15.92; P = .001], PFS [HR 4.29; 95% CI, 2.21-8.34; P < .001], and FFLRF [HR 4.63; 95% CI, 1.71-12.51; P = .007]). Immunosuppression and the presence of ≥2 pathologically involved lymph nodes were also significant adverse factors for both OS and FFLRF, although extracapsular extension was also associated with lower FFRLF. Delays to commencing PORT rather than treatment breaks accounted for the majority of cases with prolonged TPT. CONCLUSIONS:Prolongation of TPT to 14 weeks or longer may confer a lower probability of locoregional control and survival in patients with lymph node-positive cHNSCC treated with surgery and PORT. Timely referral and commencement of PORT is necessary to maximize long-term disease outcomes.


目的: 在粘膜头颈部鳞状细胞癌 (SCC) 中,治疗包时间 (TPT) 延长与较低的总生存期和局部控制相关,但皮肤HNSCC (cHNSCC) 的报道较少。右室心尖部起搏test对TPT队列患者cHNSCC. 方法: 这是一项针对淋巴结阳性cHNSCC患者的单一机构回顾性研究,涉及腮腺或颈部淋巴结,采用根治性意向手术治疗,肿瘤肉眼清除,随后进行标准分割术后放射治疗 (PORT) 从 2001 年到 2014 年。我们评估了TPT和其他预后变量对总生存期 (OS) 、cHNSCC特异性生存期 (CSS) 、无进展生存期 (PFS) 和无局部区域失败 (FFLRF) 的影响。 结果: 在本研究中,152 例患者符合纳入标准。5 年OS、CSS、PFS和FFLRF分别为 62% (9 5% 置信区间 [CI],5 4-71) 、 78% (9 5% CI,71-87) 、 5 4% (9 5% CI,46-64) 和 76% (9 5% CI,68-8 5)。在多变量模型中,TPT ≥ 14 周与所有终点不良结局相关 (OS [风险比 (HR) 4.93; 95% CI,2.54-9.56,P <。001],CSS [HR 6.09; 95% CI,2.33-15.92; P = .001],PFS [HR 4.29; 95% CI,2.21-8.34;P <.001] 和FFLRF [HR 4.63; 95% CI,1.71-12.51; P = .007])。免疫抑制和存在 ≥ 2 个病理受累淋巴结也是OS和FFLRF的显著不良因素,尽管囊外延伸也与较低的FFRLF相关。开始口岸而不是治疗中断的延迟占大多数长期TPT病例。 结论: 在接受手术和端口治疗的淋巴结阳性cHNSCC患者中,将TPT延长至 14 周或更长时间可能会降低局部区域控制和生存的概率。及时转诊和开始港口是最大限度地提高长期疾病结局的必要条件。

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.
