INTRODUCTION:A Melanoma Screening Summit was held in Brisbane, Australia, to review evidence regarding current approaches for early detection of melanomas and explore new opportunities. RESULTS:Formal population-based melanoma screening is not carried out in Australia, but there is evidence of considerable opportunistic screening as well as early detection. Biopsy rates are rising and most melanomas are now diagnosed when in situ. Based on evidence review and expert opinion, the Summit attendees concluded that there is currently insufficient information in terms of comparative benefits, harms and costs to support change from opportunistic to systematic screening. Assessment of gains in precision and cost-effectiveness of integrating total body imaging, artificial intelligence algorithms and genetic risk information is required, as well as better understanding of clinical and molecular features of thin fatal melanomas. CONCLUSIONS:Research is needed to understand how to further optimise early detection of melanoma in Australia. Integrating risk-based population stratification and more precise diagnostic tests is likely to improve the balance of benefits and harms of opportunistic screening, pending assessment of cost-effectiveness. Implications for public health: The Summit Group identified that the personal and financial costs to the community of detecting and treating melanoma are rising, and this may be mitigated by developing and implementing a more systematic process for diagnosing melanoma.


简介: 在澳大利亚布里斯班举行了黑色素瘤筛查峰会,回顾了目前黑色素瘤早期检测方法的证据,并探索了新的机会。 结果: 澳大利亚没有进行正式的基于人群的黑色素瘤筛查,但有证据表明有相当多的机会性筛查以及早期发现。活检率正在上升,大多数黑色素瘤现在在原位诊断。基于证据审查和专家意见,峰会与会者得出结论认为,目前在比较效益、危害和成本方面没有足够的信息来支持从机会性筛查向系统性筛查的转变。需要评估整合全身成像、人工智能算法和遗传风险信息的精度和成本效益,以及更好地了解薄型致死性黑色素瘤的临床和分子特征。 结论: 需要研究来了解如何进一步优化澳大利亚黑色素瘤的早期检测。整合基于风险的人群分层和更精确的诊断检测有可能改善机会性筛查的利弊平衡,等待成本效益评估。对公共卫生的影响: 峰会小组确定,检测和治疗黑色素瘤的个人和财务成本正在上升,这可以通过开发和实施更系统的黑色素瘤诊断过程来缓解。

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.
