Total Margin Control Is Superior to Traditional Margin Assessment for Treatment of Low-Stage Penile Squamous Cell Carcinoma.

PURPOSE: Penile cancer is rare, with significant morbidity and limited literature assessing utility of peripheral and deep en face margin assessment (PDEMA) vs traditional margin assessment (vertical sections) on treatment outcomes. MATERIALS AND METHODS: This was a 32-year retrospective multicenter cohort study at 3 academic tertiary care centers. The cohort consisted of 189 patients with histologic diagnosis of in situ or T1a cutaneous squamous cell carcinoma of the penis at Brigham and Women's, Massachusetts General Hospital (1988-2020), and Memorial Sloan Kettering Cancer Center (1995-2020) treated with PDEMA surgical excision, excision/circumcision, or penectomy/glansectomy. Local recurrence, metastasis, and disease-specific death were assessed via multivariable Cox proportional hazard models. RESULTS: The cohort consisted of 189 patients. Median age at diagnosis was 62 years. Median tumor diameter was 1.3 cm. The following outcomes of interest occurred: 30 local recurrences, 13 metastases, and 5 disease-specific deaths. Primary tumors were excised with PDEMA (N = 30), excision/circumcision (N = 110), or penectomy/glansectomy (N = 49). Of patients treated with traditional margin assessment (non-PDEMA), 12% had narrow or positive margins. Five-year proportions were as follows with respect to local recurrence-free survival, metastasis-free survival, and disease-specific survival/progression-free survival, respectively: 100%, 100%, and 100% following PDEMA; 82%, 96%, and 99% following excision/circumcision; 83%, 91%, and 95% following penectomy/glansectomy. A limitation is that this multi-institutional cohort study was not externally validated. CONCLUSIONS: Initial results are encouraging that PDEMA surgical management effectively controls early-stage penile squamous cell carcinoma.

Systemic Therapy for Non-Melanoma Skin Cancers: Latest Advances.

PURPOSE OF REVIEW: This review provides an update on approved and emerging systemic therapies in the treatment of locally advanced or metastatic non-melanoma skin cancers (squamous cell carcinoma, basal cell carcinoma, Merkel cell carcinoma). RECENT FINDINGS: Many studies demonstrate the effectiveness of immunotherapy for all types of non-melanoma skin cancer. For basal cell carcinoma (BCC), hedgehog inhibitors (HHI) remain first-line but with poor tolerability. Numerous clinical trials studying both neoadjuvant and adjuvant use of anti-PD-1 and anti-PD-L1 therapies in advanced NMSC are under investigation. There is a growing number of systemic therapies available to treat non-melanoma skin cancers. The advent of immunotherapy has revolutionized the field and greatly improved survival compared to historical survival rates with cytotoxic chemotherapy.

Factors predictive of recurrence, metastasis and death in node-negative penile squamous cell carcinoma: A retrospective multicentre cohort study.

BACKGROUND: Penile squamous cell carcinoma (PSCC) carries significant morbidity and mortality. Literature is limited regarding prognostic factors, especially prognostic factors for development of metastasis. OBJECTIVES: To identify independent prognostic factors associated with poor outcomes, defined as local recurrence (LR), metastasis and disease-specific death (DSD) in clinically node-negative PSCC undergoing local therapy. METHODS: Thirty-two-year Retrospective Multicenter Cohort Study of 265 patients with histologically diagnosed PSCC at three tertiary care centres. Predictive models based on patient or tumour characteristics were developed. RESULTS: Local recurrence occurred in 56 patients, metastasis in 52 patients and DSD in 40 patients. In multivariable models, the following five factors were independent prognostic factors based on subhazard ratio (SHR): history of balanitis (LR SHR: 2.3; 95% CI 1.2-4.2), poor differentiation (metastasis SHR 1.9; 95% CI 1.0-3.6), invasion into the corpora (metastasis SHR: 3.0; 95% CI 1.5-5.8 and DSD SHR: 4.5; 95% CI 1.7-12.1), perineural invasion (PNI) (metastasis SHR: 2.8; 95% CI 1.4-5.5 and DSD SHR: 3.5; 95% CI, 1.6-7.8) and a history of phimosis (DSD SHR: 2.5; 95% CI 1.2-5.3). The 5-year cumulative incidence of metastasis was higher for tumours with PNI [cumulative incidence function (CIF) = 55%, 95% CI 38-75 vs. CIF 15%, 95% CI 11-22], corporal invasion (CIF: 35%, 95% CI 26-47 vs. 12%, 95% CI 7-19) and poorly differentiated tumours (CIF = 46%, 95% CI 31-64 vs. CIF 15%, 95% CI 11-22). CONCLUSIONS: History of balanitis, history of phimosis, PNI, corporal invasion and poor differentiation are independent risk factors associated with poor outcomes. Since poor differentiation and PNI currently constitute only T1b disease, prognostic staging can likely be improved.

The American Academy of Dermatology's "Good Skin Knowledge" program enhances children and adolescents' confidence regarding dermatologic knowledge.

The American Academy of Dermatology (AAD) has resources meant to be used by children. Herein, we discuss the Good Skin Knowledge (GSK) curriculum, which was created to educate youth aged 8-13 about common dermatologic conditions to promote healthy skin habits, build self-confidence, and encourage careers in science and medicine. To assess participants' confidence regarding understanding and retention of GSK materials, the authors developed a pre- and post-training survey consisting of 10 questions. Results of our survey demonstrate a significant improvement in participants confidence regarding knowledge of skin function and care with at least two thirds of youth surveyed indicating understanding across all areas, with the largest gains centered around knowledge of the three skin layers, knowing what a dermatologist does, and appreciating the causes of acne.

Delayed medical care due to transportation barriers among US children with atopic dermatitis.

Our objective was to examine the prevalence and predictors of delayed medical care due to transportation barriers among children with atopic dermatitis (AD) living in the United States (US). We analyzed data from the 1998-2018 National Health Interview Survey, a nationally representative survey of US households. In 2018, transport-delayed care was reported for 3.4% of US children with AD, representing approximately 279,000 children annually given the National Health Interview Survey's weighted survey design, and was more common among patients of lower socioeconomic status. Targeted interventions aimed at reducing transportation barriers to healthcare among at-risk AD patients may reduce health disparities related to AD.

Importance of and instruction for starting a vitiligo patient support group.

Starting and maintaining a vitiligo support group can appear to be a daunting task. However, with proper planning and organization, the process can become manageable and rewarding. Our guide details the reasons to start a vitiligo support group, how to start a group, how to run a group, and how to promote a group. Legal protections and details regarding retention and funding are also discussed. The authors have extensive experience leading and/or assisting support groups for vitiligo and other disease states and we also sought out other current vitiligo support leaders for their valuable insights. Previous research has found that support groups for various medical conditions may have a protective effect and membership can build resilience among participants as well as foster a sense of hope regarding their disease. Further, groups can provide a network for those living with vitiligo to connect with, uplift, and learn from one another. These groups provide the opportunity to initiate lifelong connections with those facing similar circumstances and provide members with new insight and coping strategies. Members can share perspectives with one another and empower one another. We encourage dermatologists to provide vitiligo patients with support group information and to consider being involved in, starting, or otherwise supporting them.

HIV post-exposure prophylaxis in the emergency department: An updated assessment and opportunities for HIV prevention identified.

OBJECTIVES: Research suggests nonoccupational post exposure prophylaxis (nPEP) is under prescribed for people seeking treatment within 72 h of human immunodeficiency virus (HIV) exposures in the emergency department (ED). This study is an assessment of ED prescribers' knowledge, attitudes and practices regarding administration of HIV nPEP. METHODS: This was an anonymous survey based on literature review and modified Delphi technique. We approached 153 ED participants at work over a 4-month period from 5 hospital-based and 2 freestanding EDs. There were 152 completed surveys: 80 attendings, 27 residents, and 44 physician assistants. RESULTS: The majority of those surveyed (133/149, 89.3%) believe it is their responsibility to provide HIV nPEP in the ED. Although 91% (138/151) and 87% (132/151) of participants are willing to prescribe nPEP for IV drug use and unprotected sex, respectively, only 40% (61/152) of participants felt they could confidently prescribe the appropriate regimen. Only 25% (37/151) of participants prescribed nPEP in the last year. Participants considered time (27%), connecting patients to follow-up (26%), and cost to patients (23%), as barriers to prescribing nPEP. CONCLUSIONS: This study identified perceived barriers to administration of nPEP and missed opportunities for HIV prevention in the ED. Although most ED prescribers were willing to prescribe nPEP and felt it is their responsibility to do so, the majority of prescribers were not confident in prescribing it. The most commonly cited barriers to prescribing nPEP were time and access to follow-up care.
