High prevalence and little awareness in patients with chronic inflammatory skin diseases and genital involvement.

BACKGROUND: Genital involvement in patients with chronic inflammatory skin diseases is frequent, yet insufficiently acknowledged. OBJECTIVE: To evaluate the prevalence of genital symptoms in psoriasis and chronic urticaria patients, effects on quality of life, physician-patient relations and disease management. PATIENTS AND METHODS: 100 patients with psoriasis and 100 with chronic urticaria from our outpatient clinic, as well as 50 healthy controls were included. Data was collected using questionnaires developed by dermatological experts. RESULTS: Out of 250 subjects, 74 % had already experienced genital symptoms - 70 % of psoriasis patients and 58 % of urticaria patients. Seven out of ten even complained about recurrent genital involvement. 50 % of psoriasis and 41 % of urticaria patients reported an impact on quality of life. 41 % identified genital pruritus as the main symptom, with one out of three expecting a better management for this specific problem. Furthermore, 74 % complained about a lack of awareness among physicians: 79 % of urticaria patients and 58 % of psoriasis patients reported never having been questioned about genital symptoms by their physicians. CONCLUSIONS: The majority of patients with psoriasis and chronic urticaria suffer from genital involvement and an impaired quality of life. Patient and physician reported outcomes should include genital symptoms as an influencing factor for quality of life.

Response to First-Line Treatment with Immune-Checkpoint Inhibitors in Patients with Advanced Cutaneous Squamous Cell Carcinoma: A Multicenter, Retrospective Analysis from the German ADOReg Registry.

Cutaneous squamous cell carcinoma (cSCC) is a common malignancy of the skin and has an overall favorable outcome, except for patients with an advanced stage of the disease. The efficacy of checkpoint inhibitors (CPI) for advanced cSCC has been demonstrated in recent clinical studies, but data from real-world cohorts and trial-ineligible cSCC patients are limited. We retrospectively investigated patients with advanced cSCC who have been treated with CPI in a first-line setting at eight German skin cancer centers registered within the multicenter registry ADOReg. Clinical outcome parameters including response, progression-free (PFS) and overall survival (OS), time-to-next-treatment (TTNT), and toxicity were analyzed and have been stratified by the individual immune status. Among 39 evaluable patients, the tumor response rate (rwTRR) was 48.6%, the median PFS was 29.0 months, and the median OS was not reached. In addition, 9 patients showed an impaired immune status due to immunosuppressive medication or hematological diseases. Our data demonstrated that CPI also evoked tumor responses among immunocompromised patients (rwTRR: 48.1 vs. 50.0%), although these responses less often resulted in durable remissions. In line with this, the median PFS (11 vs. 40 months, p = 0.059), TTNT (12 months vs. NR, p = 0.016), and OS (29 months vs. NR, p < 0.001) were significantly shorter for this patient cohort. CPI therapy was well tolerated in both subcohorts with 15% discontinuing therapy due to toxicity. Our real-world data show that first-line CPI therapy produced strong and durable responses among patients with advanced cSCC. Immunocompromised patients were less likely to achieve long-term benefit from anti-PD1 treatment, despite similar tumor response rates.

Occupational UV-Exposure is a Major Risk Factor for Basal Cell Carcinoma: Results of the Population-Based Case-Control Study FB-181.

OBJECTIVE: The aim of this study was to investigate the role of occupational and nonoccupational ultraviolet (UV)-exposure concerning the development of basal cell carcinoma (BCC). METHODS: We undertook a population-based multicenter case-control study. Patients with first incident BCC (n = 836) were propensity score matched by age and sex to controls without skin cancer (n = 836). Sociodemographic characteristics, clinical characteristics, and lifetime UV-exposure were assessed by trained investigators. The differential estimation of occupational and nonoccupational UV-exposure dosages was based on validated instruments and established reference values. Associations were assessed using multivariable-adjusted conditional logistic regression models. RESULTS: Individuals with high levels of occupational UV-exposure were at significantly increased BCC-risk compared with individuals with low [odds ratio (OR) 1.84; 95% confidence interval (95% CI) 1.19 to 2.83 and moderate (OR 1.97; 95% CI 1.20 to 3.22) occupational UV-exposure. Nonoccupational UV-exposure was not independently associated with BCC. CONCLUSION: Skin cancer prevention strategies should be expanded to the occupational setting.
