Physician values in alopecia areata treatment decision-making: A qualitative assessment.

Background: Alopecia areata (AA) is a disease of hair loss with multiple treatment options. Physicians play an important role in guiding patients during the decision-making process. Objective: Assess physicians' values and attitudes when helping patients choose an AA treatment. Methods: Semi-structured qualitative interviews were conducted with dermatologists of varying practice type and location. Each interview was coded independently twice using inductive thematic analysis. Interrater reliability and code frequencies were determined. Results: Fourteen participants were interviewed. Interrater reliability was κ = 0.85 to 0.97. Dermatologists wanted patients to consider various treatment factors (ie, efficacy, safety, convenience of use, accessibility) and also assessed patients' AA clinical severity and personality traits. Participants often encountered various barriers to effective communication with patients, which may be mitigated by shared decision-making. Shared decision-making tools were perceived to potentially improve patient care and communication, although physicians expressed concern about lack of individualization, limitations of time, and the appropriateness of information. Conclusion: AA treatment decision-making is a complex process that often utilizes the expertise of a dermatologist, during which shared decision-making tools may be of value to both patients and physicians.

Adjuvant radiation following clear margin resection of high T-stage cutaneous squamous cell carcinoma halves the risk of local and locoregional recurrence: A dual-center retrospective study.

BACKGROUND: Although adjuvant radiation (ART) following clear margin surgery is recommended for select high-risk cutaneous squamous cell carcinomas, efficacy data are limited. OBJECTIVE: To evaluate the impact of ART on outcomes following clear margin surgery for high T-stage cutaneous squamous cell carcinomas. METHODS: A 20-year retrospective cohort study at 2 academic centers of high T-stage cutaneous squamous cell carcinomas (Brigham and Women's Hospital T2b or T3) with negative histologic margins post resection. Local recurrence (LR) and locoregional recurrence (LRR) were compared by whether tumors received ART or observation. RESULTS: A total of 508 tumors were included, of which 96 underwent ART (ART+). ART+ had a lower 5-year cumulative incidence of LR (ART+, 3.6% [95% CI, 1.6%-7.7%] vs ART-, 8.7% [95% CI, 6.3%-12.0%]) and LRR (ART+, 7.5% [95% CI, 4.4%-11.9%] vs ART-, 15.3% [95% CI, 11.9%-22.1%]). Recurrent tumors ≥6 cm or Brigham and Women's Hospital T3 tumors were classified as high-risk due to a higher 5-year cumulative incidence of LRR (High-risk, 26.3% [95% CI, 19.0%-35.7%]). High-risk tumors treated with ART had a lower 5-year cumulative incidence of LRR (ART+, 17.2% [95% CI, 11.9%-26.4%] vs ART-, 31.0% [95% CI, 26.1%-40.8%]). LIMITATIONS: Retrospective design, heterogeneous population, variations in radiation protocols. CONCLUSION: ART following clear margin surgery for high T-stage cutaneous squamous cell carcinomas resulted in half the risk of LR and LRR.

Implications of Satellitosis or In-transit Metastasis in Cutaneous Squamous Cell Carcinoma: A Prognostic Omission in Cancer Staging Systems.

IMPORTANCE: Unlike Merkel cell carcinoma and melanoma, satellitosis or in-transit metastasis (S-ITM) is not incorporated into the current cutaneous squamous cell carcinoma (CSCC) staging systems. It is important to determine if the clinical outcomes of S-ITM are relevant to prognosis for patients with CSCC. OBJECTIVES: To evaluate the association of S-ITM with clinical outcomes in patients with CSCC and to determine its prognostic implications. DESIGN, SETTINGS, AND PARTICIPANTS: A dual-institution (Cleveland Clinic and Brigham and Women's Hospital) database was queried for patients who were treated for CSCC in 2010 to 2020. Patients who were node-negative and had S-ITM-the presence of dermal lesions between the primary tumor and first-echelon lymphatic nodal basins at any point in the disease course-were identified. Subcohorts of patients with T3N0 tumors, T4N0 tumors (bone invasive), N1 to 3, and M1 disease were identified for comparison. The American Joint Committee on Cancer staging system was used to define cancer stages. Data were analyzed from January 15 to March 31, 2021. MAIN OUTCOMES AND MEASURES: Pairwise comparison of CSCC recurrence and disease-specific survival in patients with and without S-ITM was performed using Cox proportional hazard modeling. Kaplan-Meier and Fine-Gray competing risk methods were used to estimate disease-specific survival and CSCC recurrence, respectively. RESULTS: In a total of 518 patients with CSCC, S-ITM was present in 72 (13.9 %) patients (median age [range], 73.9 [31.6-95.8] years; 59 [82%] men; 69 [96%] White non-Hispanic individuals; 25 [35%] patients with immunosuppression) who were node-negative. The subcohorts were composed of 341 patients with T3N0 cancer, 36 with T4N0, 70 with N1 to 3, and 19 with M1 disease. Pairwise comparisons between disease levels using Cox proportional hazard model demonstrated lower cumulative incidence of CSCC recurrence rates in the T3N0 (HR, 0.21; 95% CI, 0.14-0.30; P < .001) and T4N0 (HR, 0.36; 95% CI, 0.19-0.68; P = .001) cohorts compared with the S-ITM cohort. No significant difference was observed between patients who were node-positive and those with S-ITM (HR, 0.74; 95% CI, 0.48-1.14; P = .16). The 5-year disease-specific survival rates were 76% for T3N0, 64% for T4N0, 41% for S-ITM, and 39% for N1 to 3. Compared with the S-ITM cohort, DSS was significantly higher in the T3N0 (HR, 0.23; 95% CI, 0.15-0.35; P < .0001) and T4N0 (HR, 0.37; 95% CI, 0.19-0.76; P = .01) cohorts, and not significantly different in the node-positive (HR, 0.77; 95% CI, 0.84-3.93; P = .30) and metastatic cohorts (HR, 1.81; 95% CI, 0.84-3.93; P = .13). CONCLUSIONS AND RELEVANCE: This multi-institutional cohort study found that patients with CSCC and S-ITM appear to have clinical outcomes comparable to those of patients who are node-positive, and an increased risk of recurrence and worse survival compared with patients who have T3 and T4 disease. These outcomes are similar to those observed for Merkel cell carcinoma and melanoma. Given that S-ITM may be a powerful prognostic factor, it should be incorporated into clinical staging systems.

Higher metastasis and death rates in cutaneous squamous cell carcinomas with lymphovascular invasion.

BACKGROUND: Lymphovascular invasion (LVI) is an aggressive histologic finding but is excluded from current staging systems due to its lack of demonstrated independent prognostic significance. OBJECTIVE: To evaluate the impact of LVI on cutaneous squamous cell carcinoma tumor outcomes. METHODS: In total, 10,707 cutaneous squamous cell carcinoma tumors from a 20-year, retrospective, multicenter cohort were stratified by the presence (LVI+) or absence (LVI-) of LVI. Outcomes (local recurrence, in-transit metastasis, nodal metastasis, disease-specific death) were compared based on low (Brigham and Women's Hospital [BWH] stage T1/T2a) and high (BWH T2b/T3) tumor stages. RESULTS: Of the 10,707 tumors, 78 had LVI. The analysis of low-stage BWH tumors showed the LVI+ group had a significantly higher 5-year cumulative incidence of local recurrence (LVI+: 12.3%; LVI-: 1.1%; P < .01), metastasis (LVI+: 4.2%; LVI-: 0.4%; P < .01), and disease-specific death (LVI+: 16.2%; LVI-: 0.4%; P < .01). The analysis of BWH high-stage tumors showed the LVI+ group maintained a higher 5-year cumulative incidence of metastasis (LVI+: 28.5%; LVI-: 16.8%; P = .06) and disease-specific death (LVI+: 25.3%; LVI-: 13.9%; P = .03), however, there was no difference in local recurrence (LVI+: 16.3%; LVI-: 15.8%; P = .11). LIMITATIONS: Retrospective study design. CONCLUSION: LVI+ cutaneous squamous cell carcinomas have higher rates of metastasis and death at 5 years. Future staging systems should consider incorporating LVI.

Non-Surgical Treatments for Keratinocyte Carcinomas.

Skin cancer is the most common malignancy worldwide, comprising approximately 30% of all human tumors. In recent decades, the incidence of keratinocyte carcinomas, which include basal cell carcinoma and cutaneous squamous cell carcinoma, has been steadily increasing globally (Rogers et al. in JAMA Dermatol 151(10):1081-1086. https://doi.org/10.1001/jamadermatol.2015.1187 , 2015; Nehal and Bichakjian in N Engl J Med 379(4):363-374. https://doi.org/10.1056/nejmra1708701 , 2018). Most tumors are cured with surgical excision; however, some tumors are best treated with non-surgical approaches. Superficial tumors can often be cured with non-surgical methods whereas more advanced stage tumors may not be amenable to surgery. Additionally, surgical treatment may not be available for all populations depending on geographic location and accessibility to care. This article reviews commonly utilized nonsurgical options such as cryotherapy, photodynamic therapy, topical treatments, and radiation as well as systemic treatments including immunotherapies and chemotherapies.

Recognition and Management of Cutaneous Connective Tissue Diseases.

Connective tissue diseases (CTDs) encompass a broad spectrum of clinical presentations that involve multidisciplinary management. Cutaneous findings are common in CTD and careful examination of these features aids in appropriate diagnosis and subsequent evaluation. Thorough work-up of CTD is crucial to properly identify disease subtypes and systemic involvement. Management plans can be developed based on diagnosis and systemic manifestations of disease. Disease management often requires treatment with pharmacotherapies with potential for toxicities, further underscoring the importance of diagnostic accuracy in this patient population. Evolving research strives to better elucidate the pathogenic mechanisms of CTDs allowing for more targeted treatment modalities.

Basal Cell Carcinoma Review.

Basal cell carcinoma (BCC) is the most common malignancy and the incidence is rising. BCCs have low mortality but can cause significant morbidity primarily through local destruction. The pathogenesis is linked to the interplay between environmental and patient-derived characteristics. There are multiple therapeutic modalities, and appropriate selection requires knowledge of complications, cosmetic outcomes, and recurrence rates. This article reviews the epidemiology, staging, treatment, and prevention of BCC.
