Abstract

OBJECTIVES:With the introduction of novel immune therapeutics for the treatment of disseminated malignancies, we sought to evaluate whether deliberate sequencing of immunotherapy before/after conventional cytotoxic chemotherapy would have an impact on clinical outcomes in patients with previously treated metastatic melanoma. We sought to evaluate whether or not ipilimumab immunotherapy administered before or after cytotoxic chemotherapy (nab-paclitaxel+bevacizumab, AB) would impact clinical outcomes. METHODS:We conducted a randomized phase 2 clinical trial of patients with BRAF wild-type metastatic melanoma (up to 2 prior therapies) who received either: (A) AB followed by ipilimumab therapy at progression; or (B) ipilimumab followed by AB treatment at progression. The primary goal of the study was a comparison of AB versus ipilimumab progression-free survival, with secondary clinical and laboratory endpoints. RESULTS:This study did not reach full accrual due to concurrent Food and Drug Administration approval of anti-programmed cell death 1 agents. Nevertheless, the available data suggests a cumulative therapeutic advantage to the sequential use of ipilimumab followed by AB. Correlative laboratory data revealed a favorable effect on systemic immune homeostasis in patients receiving AB therapy, of potential interest in further investigations, especially in the context of chemotherapy/immunotherapy combinations. CONCLUSION:Albeit limited in scope, our data suggest that cytotoxic therapy with nab-paclitaxel and bevacizumab appear to favorably alter systemic parameters of immune function of potential benefit in combination T-cell directed immune checkpoint inhibitor therapy.

摘要

目的: 随着治疗播散性恶性肿瘤的新型免疫疗法的引入,我们试图评估传统细胞毒性化疗前/后免疫治疗的刻意测序是否会对既往治疗过的转移性黑色素瘤患者的临床结局产生影响。我们试图评估在细胞毒性化疗 (nab-紫杉醇 + 贝伐单抗,AB) 之前或之后给予ipilimumab免疫治疗是否会影响临床结局。 方法: 我们进行了一项随机相位 2 临床试验的患者BRAF野生型转移性黑素瘤 (高达 2 之前疗法) 接受 :( a) AB后行ipilimumab治疗; 或 (B) ipilimumab后行AB治疗。该研究的主要目标是比较AB与ipilimumab无进展生存期,以及次要临床和实验室终点。 结果: 由于食品和药物管理局同时批准抗程序性细胞死亡 1 剂,本研究未达到完全应计。尽管如此,现有数据表明,序贯使用ipilimumab后使用AB具有累积治疗优势。相关实验室数据显示,在接受AB治疗的患者中,对全身免疫稳态有有利影响,对进一步研究有潜在兴趣,特别是在化疗/免疫治疗组合的背景下。 结论: Albei t limi t ed在范围内,我们的da t a建议t t ha t cy t o t oxic t herapy wi t h nab-pacli t axel和bevacizumab出现t o有利al t er sys t emic parame t ers免疫功能t离子po t en t院内的benefi t在组合t离子T-细胞direc t ed免疫checkpoin t抑制t或t herapy.

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.

皮肤肿瘤是发生在皮肤的细胞增生性疾病,是一种常见病。发生于皮内或皮下组织的新生物,种类很多,临床上分良性肿瘤和恶性肿瘤。恶性肿瘤可以不断增殖,引起转移,威胁生命,称为皮肤癌。
