ABSTRACT

BACKGROUND: The discovery of signaling networks that drive oncogenic processes has led to the development of targeted anticancer agents. The burden of pigmentary adverse events from these drugs is unknown. OBJECTIVE: To conduct a systematic review and meta-analysis of published clinical trials and determine the incidence and risk of development of targeted therapy-induced pigmentary changes. METHODS: A comprehensive search was conducted to identify studies reporting targeted therapy-induced pigmentary changes. The incidence and relative risk were calculated. Case reports and series were reviewed to understand clinical characteristics. RESULTS: A total of 8052 patients from 36 clinical trials were included. The calculated overall incidences of targeted cancer therapy-induced all-grade pigmentary changes in the skin and hair were 17.7% (95% confidence interval [CI], 11.9-25.4) and 21.5% (95% CI, 14.9-30.1), respectively. The relative risk of all-grade pigmentary changes of skin and hair were 93.7 (95% CI, 5.86-1497.164) and 20.1 (95% CI, 8.35-48.248). Across 53 case reports/series (N = 75 patients), epidermal growth factor receptor and breakpoint cluster region-abelson inhibitors were the most common offending agents. LIMITATIONS: Potential under-reporting and variability in oncologists reporting these events. CONCLUSION: There is a significant risk of development of pigmentary changes during treatment with targeted anticancer therapies. Appropriate counseling and management are critical to minimize psychosocial impairment and deterioration in quality of life.

ABSTRACT

BACKGROUND: Peristomal dermatitis is a common complication for the >700 000 patients in the United States with an ostomy. The role of stoma skin care products in peristomal dermatitis is poorly understood. OBJECTIVE: To evaluate stoma skin care products as a cause of peristomal dermatitis. METHODS: A retrospective chart review of patients with peristomal dermatitis at four academic hospitals from January 2010 to March 2014 was performed. Patient demographics, clinical information and use test and patch test results were documented. RESULTS: Eighteen patients identified as having peristomal dermatitis were tested. Twelve of these had peristomal contact dermatitis. We identified numerous stoma skin care products as triggers of irritant and/or allergic contact dermatitis. The most common stoma skin care product used and/or involved in dermatitis was Cavilon™ No Sting Barrier Film. CONCLUSIONS: Our data support a paradigm shift whereby healthcare workers treating patients with peristomal dermatitis, which is currently considered to be a reaction mainly to bodily fluids, must consider those products used to protect the skin as potential triggers for this disease. Therefore, patients with peristomal dermatitis should be tested with their stoma skin care agents to determine the need for removal or change of these products. Additionally, full ingredient labelling by manufacturers would help identify new allergens and irritants.

ABSTRACT

Taxanes (docetaxel and paclitaxel) are among the most commonly prescribed anticancer drugs approved for the treatment of metastatic or locally advanced breast, non-small cell lung, prostate, gastric, head and neck, and ovarian cancers, as well as in the adjuvant setting for operable node-positive breast cancers. Although the true incidence of dermatological adverse events (AEs) in patients receiving taxanes is not known, and has never been prospectively analysed, they clearly represent one of the major AEs associated with these agents. With an increase in the occurrence of cutaneous AEs during treatment with novel targeted and immunological therapies when used in combination with taxanes, a thorough understanding of reactions attributable to this class is imperative. Moreover, identification and management of dermatological AEs is critical for maintaining the quality of life in cancer patients and for minimizing dose modifications of their antineoplastic regimen. This analysis represents a systematic review of the dermatological conditions reported with the use of these drugs, complemented by experience at comprehensive cancer centres. The conditions reported herein include skin, hair, and nail toxicities. Lastly, we describe the dermatological data available for the new, recently FDA-and EMA- approved, solvent-free nab-paclitaxel.

ABSTRACT

Lupus miliaris disseminatus faciei, a chronic inflammatory disorder, is a controversial and enigmatic diagnostic/therapeutic entity. Multiple, discrete, smooth 1-3 mm brown/red or brown-to-yellowish dome-shaped papules (sometimes with mild scaling) are its clinical characteristics. The lesions are usually located on the central and lateral side of the face. The condition is most often seen in young adults of both sexes, and diascopy may reveal apple-jelly nodules. Lupus miliaris disseminatus faciei has clearly been defined into four histopathologic groups: epithelioid cell granuloma with central necrosis; epithelioid cell granuloma without central necrosis (sarcoid/foreign body reaction); epithelioid cell granuloma with abscesses; and nongranulomatous, nonspecific inflammatory infiltrate. While in early lesions granuloma is absent and lymphocytes and a few neutrophils surround the follicles, fully developed lesions show well formed granuloma surrounding ruptured hair follicles, often with large numbers of neutrophils. Lupus miliaris disseminatus faciei must be differentiated from other conditions; to facilitate this, in Part I of this paper the histopathologic undertones were delineated into early, intermediate (first stage, second stage, and third stage), and late stages. This part of the article presents an overview of lupus miliaris disseminatus faciei.
