ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
This study underscores the persistent underrepresentation of women in academic dermatology leadership positions by examining the gender composition of editorial boards across top dermatology journals, emphasizing the urgent need for proactive strategies to promote diversity, equity, and inclusion.

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.

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.

OBJECTIVE: To assess rates of breast and cervical cancer screening at student-run free clinics to understand challenges and strategies for advancing quality and accessibility of women's health screening. METHODS: The authors performed a systematic search of publications in Ovid MEDLINE, PubMed, Web of Science, and Google Scholar databases from database inception to 2020. English-language publications assessing rates of breast and cervical cancer screening in student-run free clinics were included. Structured data extraction was completed for each publication by two reviewers independently. Risk of bias was assessed using a modified Agency for Healthcare Research and Quality checklist. Results were synthesized qualitatively because of study heterogeneity. RESULTS: Of 3634 references identified, 12 references met study inclusion criteria. The proportion of patients up-to-date on breast cancer screening per guidelines ranged from 45% to 94%. The proportion of patients up-to-date on cervical cancer screening per guidelines ranged from 40% to 88%. CONCLUSION: Student-run free clinics can match breast and cervical cancer screening rates among uninsured populations nationally, although more work is required to bridge the gap in care that exists for the underinsured and uninsured.

Background: The American Academy of Dermatology and the Food and Drug Administration recommend consultation with a dermatologist prior to undergoing laser tattoo removal. However, non-health care professionals offer tattoo removal. Understanding the information available on the internet for patients regarding tattoo removal is important given that individuals are increasingly consulting digital sources to make decisions regarding skin care. Prior research has identified that YouTube contains misinformation on dermatologic health. Objective: Here, we present a cross-sectional study that determined the sources of information in YouTube videos that discuss tattoo removal and described the content presented to viewers. Methods: Using the query "tattoo removal," we reviewed English-language YouTube videos that explicitly discussed tattoo removal. The following data were recorded: profession of the presenter, tattoo removal method discussed, whether an explicit recommendation to see a dermatologist or physician was present in the video, and number of views. Results: We analyzed 162 YouTube videos. We found that the majority were presented by non-health care professionals (n=125, 77%), with only 4 (3.7%) records of this subset recommending viewers to seek consultation from a dermatologist to ensure safe and adequate tattoo removal. Conclusions: Based on our findings, we recommend that dermatologists and other health care professionals provide high-quality, evidence-based information to viewers on tattoo removal and encourage dermatology societies to share via their social media platforms information about the importance of consulting a dermatologist for tattoo removal.
