Abstract

BACKGROUND:Many high cost treatments for advanced melanoma have become available in recent years. National health technology assessment agencies have raised concerns regarding uncertainty in their clinical and cost-effectiveness. OBJECTIVE:The aim of this systematic review is to identify economic evaluations of treatments for advanced melanoma and review model assumptions, outcomes, and quality as preparation for a health technology assessment. METHODS:A search of Embase, MEDLINE, EconLit, and the Cochrane Database was conducted. Only studies using decision-analytic models were included. Two authors independently completed full-text review and data extraction. RESULTS:Fifteen studies were identified. There were major differences in the structural assumptions underpinning the models. There was general agreement in study conclusions, although the predicted costs and quality-adjusted life years for each treatment varied. BRAF monotherapy (vemurafenib, dabrafenib) or BRAF/MEK combination therapy (BRAF monotherapy with cobimetinib or trametinib) has not been shown to be cost-effective in any jurisdiction. PD-1 inhibitors (pembrolizumab, nivolumab) are consistently found to be cost-effective compared with ipilimumab, although their cost-effectiveness compared with chemotherapy is not established. Combination therapy with nivolumab and ipilimumab is unlikely to be cost-effective in any setting. One study including all agents found that none of the new treatments were cost-effective relative to chemotherapy. Publication of the study in a health economics journal is associated with better reporting of and higher-quality assessment than those published in clinical journals. CONCLUSION:Despite differences in model structures and assumptions, the conclusions of most included studies were consistent. Health technology assessment has a key role in maximizing value from high-cost innovative treatments. Consideration should be given to divestment from BRAF/MEK inhibitors and ipilimumab in favor of reimbursement of PD-1 inhibitors.

摘要

背景: 近年来,许多晚期黑色素瘤的高成本治疗已经成为可用的。国家卫生技术评估机构对其临床和成本效益的不确定性提出了担忧。 目的: 本系统综述的目的是确定晚期黑色素瘤治疗的经济学评价,并回顾模型假设、结果和质量,作为卫生技术评估的准备。 方法: 检索Embase、MEDLINE、EconLit和Cochrane数据库。仅纳入使用决策分析模型的研究。由两名作者独立完成全文综述和资料提取。 结果: 确定了 15 项研究。支撑模型的结构假设存在重大差异。研究结论普遍一致,尽管每种治疗的预测成本和质量调整生命年各不相同。BRAF单药治疗 (vemurafenib、dabrafenib) 或BRAF/MEK联合治疗 (BRAF单药治疗与cobimetinib或trametinib) 在任何司法管辖区均未显示成本效益。PD-1 抑制剂 (pembrolizumab,nivolumab) 与ipilimumab相比一直被发现具有成本效益,尽管它们与化疗相比的成本效益尚未确定。Nivolumab和ipilimumab联合治疗在任何情况下都不太可能具有成本效益。一项包括所有药物在内的研究发现,相对于化疗,没有一种新的治疗方法具有成本效益。该研究发表在卫生经济学杂志上,与发表在临床期刊上的报告和更高质量的评估相关。 结论: 尽管模型结构和假设存在差异,但大多数纳入研究的结论是一致的。卫生技术评估在高成本创新治疗中发挥最大价值的关键作用。应考虑从BRAF/MEK抑制剂和ipilimumab中撤资,支持报销PD-1 抑制剂。

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.
