Risk for second primary cancers among pediatric and young adult melanoma survivors.

BACKGROUND/OBJECTIVES: Second primary cancers (SPCs) are a leading cause of morbidity and mortality among cancer survivors. In this study, we aimed to characterize the incidence of SPCs among pediatric and young adult survivors of CM. METHODS: Using the Surveillance, Epidemiology, and End Results Program data spanning 2000-2018, we calculated standardized incidence ratios (SIR) to assess SPC risk in all pediatric (0-18 years) and young adult (19-29 years) patients with a first primary cancer diagnosis of CM. RESULTS: Of 7,169 total CM survivors, 632 (8.82%) developed a SPC, corresponding to a 5-fold increased risk (standardized incidence ratio [SIR] 4.98; 95% confidence interval [CI] 4.60-5.38) compared to the general population. There was a highly elevated risk for second primary melanoma across all age groups (SIR 32.5; 95% CI 29.7-35.6), constituting the majority of SPC diagnoses (N = 485). Infants diagnosed with CM before 1 year of age had the highest risk for any SPC (SIR 164; 95% CI 19.8-592) and young adults diagnosed at 25-29 years had the lowest risk (SIR 4.64; 95% CI 4.19-5.13). SPC incidence was highest within the first year of CM diagnosis (SIR 27.5; 95% CI 23.7-31.6) and progressively decreased with time. CONCLUSIONS: Variation exists in the incidence and type of SPC according to age among pediatric and young adult survivors of CM.

Bortezomib-Induced Reticular Eruption in Patient with Multiple Myeloma.

Bortezomib is the first proteasome inhibitor to treat a variety of malignancies and is currently part of the standard of care regimen for the initial treatment of patients with newly diagnosed multiple myeloma. While bortezomib is generally well tolerated, it has been associated with various side effects, which have limited its use in some patients. Here, we describe a unique case with histological confirmation of a reticular eruption that appeared at the site of a subcutaneous administration of bortezomib in a 62-year-old male who was newly diagnosed with IgG kappa multiple myeloma. A skin biopsy was performed, which revealed superficial perivascular dermatitis predominantly composed of lymphocytes with rare eosinophils. The patient was successfully treated with betamethasone dipropionate 0.05% cream. When consulted, dermatologists should advise the oncology team of multiple myeloma patients treated with bortezomib to maintain a high threshold before discontinuing the drug when a patient experiences an atypical, reticular rash following subcutaneous administration. Additionally, potent topical corticosteroids, such as betamethasone dipropionate 0.05% cream, should be considered in managing the cutaneous reticular eruptions related to bortezomib administration, in order to maintain an optimal treatment regimen for patients with multiple myeloma.

Modulation of Inflammatory Proteins in Serum May Reflect Cutaneous Immune Responses in Cancer Immunotherapy.

Diphencyprone (DPCP), a topical contact sensitizer, has shown efficacy in treating cutaneous melanoma metastases, including at times beyond the directly treated sites, but biomarkers indicative of treatment response have not been characterized. Thus, we performed a proteomic analysis of the skin and serum of five patients with cutaneous melanoma metastases treated with DPCP on days 0, 63, and 112 of the treatment course. In the serum, we found a significant upregulation (P < 0.05) in 13 of 96 assessed immuno-oncology proteins after DPCP treatment. Upregulated proteins included those of the T helper 1 axis (CXCL9, CXCL10), immune checkpoint proteins (PD-1), and various proteins with roles in promoting tumor immunity such as CD80 and TNFRSF4/9. Given the positive clinical response to topical treatment noted in the five patients studied, these proteins may represent prognostic biomarkers in the serum for evaluating the efficacy of DPCP treatment of cutaneous melanoma metastases. Because DPCP does not lead to nonspecific immune-related adverse events seen with immune checkpoint inhibitors, our study provides evidence for potential tumor-specific systemic immune activation and systemic antitumor effectors elicited by topical DPCP.

Online Health Information for Acne Keloidalis Nuchae has a Difficult Level of Readability.

BACKGROUND: Acne keloidalis nuchae (AKN) is an inflammatory disorder primarily seen in individuals of color, characterized by acneiform and keloidal lesions on the occipital scalp/nuchal region. More than 50% of patients with keloids are known to search their condition on the internet. We sought to determine the level of readability of patient education materials (PEM) available to patients. The term 'acne keloidalis nuchae' was searched and screened for the top 100 search results on the Google® search engine. For evaluation, 6 readability metrics (Flesch-Kincaid grade level, Gunning Fog index, Coleman-Liau index, SMOG index, automated readability, and Linsear Write Formula) were collected by entering text from each reference site into an automatic readability calculator for computation. Median readability scores of AKN PEMs ranged from 10.3th to 13.5th grade levels. Overall, readability median above the 8th-grade level were consistently seen across all 6 readability measures, with some median scores reaching university undergraduate levels. More readable educational tools are needed for acne keloidalis nuchae online. J Drugs Dermatol. 2023;21(2):195-196. doi:10.36849/JDD.7110.

Ichthyosis, cataracts, and motor delay in an infant: A case of Chanarin-Dorfman syndrome.

Chanarin-Dorfman syndrome (CDS) is a rare, autosomal recessive disorder of impaired triacylglycerol catabolism leading to cytoplasmic deposition of triglycerides in various cell types. We describe the case of an 8-month-old boy with cataracts, strabismus, motor delays, and an ichthyosiform rash since birth. Genetic testing revealed a pathogenic variant of the ABHD5 gene, suggestive of CDS, and further workup demonstrated hepatic steatosis and myopathy. His ichthyosis improved with initiation of a diet low in very long-chain fatty acids and medium-chain fatty acid supplementation.

Accelerated Healing from Severe Radiation Dermatitis Using Noncontact, Low-frequency Ultrasound-assisted Saline Wash Therapy.

ABSTRACT: Radiotherapy (RT) is a modality for cancer management that frequently causes critical injury to tissues adjacent to the targeted cancer site. Acute radiation dermatitis (RD) is one of the most common adverse effects of RT and may lead to secondary infection, disfigurement, and discontinuation of therapy. The authors report the efficacy of a multidisciplinary collaboration between radiation oncology, dermatology, and wound care teams in the management of severe, acute RD. This case report describes the use of noncontact, low-frequency ultrasound (NCLFU)-assisted saline wash therapy leading to accelerated healing of severe RD in an older man treated with RT for scalp squamous cell carcinoma. Although NCLFU-assisted saline wash therapy provides gentle debridement of wound surfaces and has demonstrated efficacy in the management of chronic wounds, the potential role for NCLFU therapy in RD management has not yet been explored.

Unique protein signatures evolve during the course of a delayed-type hypersensitivity reaction in human skin.

Diphencyprone (DPCP) is a hapten that causes a delayed-type hypersensitivity reaction when applied topically. It has clinical uses in the treatment of various conditions such as melanoma metastases, warts, and alopecia areata, but the mechanisms are currently not well understood in humans. To further characterize the immunologic effects of DPCP, the authors performed a proteomic analysis of normal skin of eight healthy volunteers following a single application of DPCP and compared them with placebo-treated skin from the same volunteers. A total of 96 proteins were examined using the Olink immuno-oncology panel at 3 days (peak response), 14 days (partially resolved response), and 120 days (completely resolved response). Our analysis revealed significant upregulation of markers of immune cell activation (interleukin [IL] 8), vascular and tissue remodeling (matrix metallopeptidase 12 [MMP12], nitric oxide synthase 3 [NOS3]), antineoplastic markers (granzyme B [GZMB]), and the Th1 axis (interferon gamma [IFNG], chemokine (C-X-C motif) ligand [CXCL] 9, CXCL10, CXCL11) at days 3 and 14 compared with placebo (p < 0.05). In addition, several negative regulators of immune function such as programmed cell death 1 (PD1), programmed cell death ligand 1 (PDL1) (p < 0.001), and lymphocyte activation gene 3 (LAG3) (p < 0.05) were significantly upregulated at days 3 and 14. This induction of negative regulators may explain the seemingly paradoxical therapeutic benefits of DPCP in autoimmune conditions such as alopecia areata. The current analysis also indicated IL-4 upregulation only at day 3, followed by IL-12 upregulation only at day 14, suggesting a transient Th2 response followed by Th1 polarization. Overall, these data suggest a complex and evolving immunological delayed-type hypersensitivity response to a single application of DPCP over time. Future proteomic studies of samples from patients with melanoma metastases, warts, and alopecia areata treated long term with DPCP are needed to further evaluate its pharmacologic mechanisms.

Risk of Nonkeratinocyte Skin Cancers in People Living with HIV during the Era of Antiretroviral Therapy.

Antiretroviral therapy may alter susceptibility to nonkeratinocyte skin cancers (NKSCs) by improving immunity in people living with HIV. Using linked data from HIV and cancer registries in 12 states/regions in the United States during the antiretroviral therapy era (1996‒2018), we calculated standardized incidence ratios for 27 NKSCs, comparing incidence with that of the general population. Risk factors for NKSCs were evaluated using Poisson regression. There were 2,743 NKSCs diagnosed in 585,706 people living with HIV followed for 4,575,794 person-years. Kaposi sarcoma was the most common cancer (82%), followed by melanoma (12%) and cutaneous lymphoma (2.6%). Incidence was elevated for virus-related NKSCs: Kaposi sarcoma (standardized incidence ratio = 147, 95% confidence interval = 141‒153), diffuse large B-cell lymphoma (standardized incidence ratio = 5.19, 95% confidence interval = 3.13‒8.11), and Merkel cell carcinoma (standardized incidence ratio = 3.15, 95% confidence interval = 1.93‒4.87); elevated incidence for diffuse large B-cell lymphoma and Merkel cell carcinoma was observed only among people living with HIV with a previously acquired immunodeficiency syndrome diagnosis. Kaposi sarcoma risk was highest among men who have sex with men. Incidence was not increased for melanoma, adnexal carcinomas, and sarcomas. Melanoma and Merkel cell carcinoma arose disproportionately on sun-exposed skin, supporting a role for UVR in their development. In conclusion, risk for most NKSCs was similar to that of the general population during the antiretroviral therapy era, suggesting that people living with HIV without NKSC risk factors may not require intensive skin surveillance.

Implementation of a dermatology skin of color educational module for medical students.

Research in dermatology education highlights the lack of skin of color (SOC) instruction for medical students, leading to concerning healthcare outcomes. Because of the already limited opportunity for students to have dedicated teaching in pathophysiology, management, and treatment of dermatologic diseases in medical school, we developed an educational module that addresses these gaps. We created a one-hour virtual lecture for medical students focused on common skin diseases tested on the United States Medical Licensing Examination with visual images across all skin types. A questionnaire was administered before and after the educational module to assess outcomes comparing disease identification in lighter (Fitzpatrick scale I-III) versus darker (Fitzpatrick scale IV-VI) skin tones and to determine medical school student attitudes. An analysis of 43 examination scores before, and after attending the educational module determined rosacea, psoriasis, and basal cell carcinoma to be conditions in SOC patients that demonstrated the most significant improvement (47.3%, 54.9%, and 30.8%, respectively). Our results also highlighted worse performance outcomes for diseases in SOC in the pre-examination questionnaire. Thus, our study indicates that a concise education module focused on disease presentations inclusive of all skin types may efficiently increase students' ability to identify diseases commonly misdiagnosed in the clinical setting.

Proteomic profiling of a patient with cutaneous melanoma metastasis regression following topical contact sensitizer diphencyprone and immune checkpoint inhibitor treatment.

Immune checkpoint inhibitors (ICIs) such as pembrolizumab have revolutionized the treatment of advanced melanoma, but many patients do not respond to ICIs alone, and thus there is need for additional treatment options. Topical immunomodulators such as diphencyprone (DPCP) also have clinical use in advanced melanoma, particularly in the treatment of cutaneous metastases. In a previous report, we characterized the enhanced clinical response to dual agent immunotherapy with pembrolizumab and DPCP in a patient with cutaneous melanoma metastases. To improve mechanistic understanding of this response, we analyzed proteomic data using the Olink immuno-oncology panel of 96 biomarkers from tissue and serum samples of this patient throughout his treatment course. Particular attention was paid to programmed death-1 (PD-1), programmed death-ligand 1 (PD-L1), and lymphocyte-activation gene 3 (LAG-3) given they are all targeted by ICIs in clinical practice. These proteins were upregulated during the period of DPCP monotherapy, then downregulated during pembrolizumab monotherapy, and then robustly upregulated again during dual therapy. Although not exclusively, the induction of checkpoint inhibitor proteins in the presence of DPCP suggests potential synergy between this agent and ICIs in the treatment of cutaneous melanoma metastases. Large-scale investigation is warranted to further evaluate this potential novel combination therapeutic approach.
