Cemiplimab for Locally Advanced and Metastatic Cutaneous Squamous-Cell Carcinomas: Real-Life Experience from the French CAREPI Study Group.

Although cemiplimab has been approved for locally advanced (la) and metastatic (m) cutaneous squamous-cell carcinomas (CSCCs), its real-life value has not yet been demonstrated. An early-access program enrolled patients with la/mCSCCs to receive cemiplimab. Endpoints were best overall response rate (BOR), progression-free survival (PFS), overall survival (OS), duration of response (DOR) and safety. The 245 patients (mean age 77 years, 73% male, 49% prior systemic treatment, 24% immunocompromised, 27% Eastern Cooperative Oncology Group performance status (PS) ≥ 2) had laCSCCs (35%) or mCSCCs (65%). For the 240 recipients of ≥1 infusion(s), the BOR was 50.4% (complete, 21%; partial, 29%). With median follow-up at 12.6 months, median PFS was 7.9 months, and median OS and DOR were not reached. One-year OS was 73% versus 36%, respectively, for patients with PS < 2 versus ≥ 2. Multivariate analysis retained PS ≥ 2 as being associated during the first 6 months with PFS and OS. Head-and-neck location was associated with longer PFS. Immune status had no impact. Severe treatment-related adverse events occurred in 9% of the patients, including one death from toxic epidermal necrolysis. Cemiplimab real-life safety and efficacy support its use for la/mCSCCs. Patients with PS ≥ 2 benefited less from cemiplimab, but it might represent an option for immunocompromised patients.

Use of Systemic Medications for Treating Adult Atopic Dermatitis in France: Results of a Practice Survey.

PURPOSE: Recent studies have illustrated that systemic medications are underused for treating adult atopic dermatitis (AD) and that dermatologists have concerns regarding the safety profile of cyclosporine in AD. PATIENTS AND METHODS: We performed a national online practice survey between March and April 2020. RESULTS: A total of 305 dermatologists responded, 57% with hospital-based activity and 43% with private practice. Overall, 46.9% prescribed cyclosporine for adult AD. Before initiating treatment, 56.9% did not perform evaluation scoring. Reasons for not prescribing cyclosporine were no eligible patients (24.7%), lack of information (52.6%), need for hospital prescription (31.2%), and lack of experience (79.2%). Fifty-four percent of the dermatologists prescribed methotrexate for adult AD. Before initiating treatment, 50.5% did not perform evaluation scoring. Reasons for not prescribing methotrexate were no eligible patients (46.7%), lack of information (39.3%), lack of experience (25.2%), and not approved for AD (47.4%). A total of 2.1% dermatologists prescribed other systemic treatments for adult AD, 9.8% prescribed corticosteroids and 56.4% prescribed dupilumab. CONCLUSION: Systemic treatments for AD are used by half of dermatologists, although cyclosporine and dupilumab must be initiated in hospitals in France. Methotrexate is more frequently used than cyclosporine, although it is not approved for this indication in France. A vast majority of dermatologists do not perform any evaluation scoring before initiating systemic treatment for adult AD.

Effectiveness and Safety of Anti-interleukin-17 Therapies in Elderly Patients with Psoriasis.

Anti-interleukin-17 agents have recently been developed for the treatment of psoriasis. This study evaluated the tolerance and effectiveness of anti-interleukin-17 agents for psoriasis in elderly patients in daily practice. A multicentre, retrospective study was performed, involving psoriatic patients aged ≥65 years who had received an anti-interleukin-17 agent, including secukinumab, ixekizumab or brodalumab. A total of 114 patients were included: 72 received secukinumab, 35 ixekizumab, and 7 brodalumab. Treatment was stopped in 32 patients (28.9%), because of relapses in 14 patients (41.2%), primary failures in 11 patients (32.4%), or adverse events in 7 patients (20.6%). The 3 most frequently reported adverse events were injection site reactions (n = 4), oral candidiasis (n = 3), and influenza-like illness (n = 3). Regarding effectiveness, 80 patients (70%) reached a Physician Global Assessment score of 0/1, 6 months after treatment initiation. In conclusion, anti-interleukin-17 therapy appears to be an effective and safe therapeutic option for psoriasis treatment in patients aged ≥ 65 years.

Corticosteroid treatment for melanoma-associated retinopathy: effect on visual acuity and electrophysiologic findings.

BACKGROUND: Visual disturbance in the course of melanoma is rare. Specific localized metastases and drug toxic effects are frequently the cause. Recognition of a retinopathy raises several questions when the diagnosis of melanoma-associated retinopathy (MAR) can be confirmed. Descriptions of such patients in dermatologic literature are rare and deserve attention because therapeutic decisions are mandatory. OBSERVATIONS: A 70-year-old woman had a first melanoma in 1985 and a second primary melanoma in 1994. Axillary lymph node involvement occurred in November 2000, leading to surgery and chemotherapy. In December 2001, she had sudden bilateral visual loss, with shimmering blobs of color and flickering photopsias. Computed tomography and cerebral magnetic resonance imaging ruled out localized tumor on the eyes or optic nerves or evolution of disease. Ophthalmologic examination revealed a bilateral posterior uveitis, with hyalitis and progressive destruction of retinal pigment. The electrophysiologic data confirmed the diagnosis of MAR. Symptoms improved after systemic corticosteroid therapy, with no relapse after tapering doses despite worsening of melanoma. CONCLUSIONS: As a rare paraneoplastic visual syndrome possibly leading to blindness, MAR is characterized by bipolar cell involvement without photoreceptor cell impairment. Also, MAR is linked to the presence of autoantibodies directed against melanoma antigens that cross-react with the rod bipolar cells of the retina. Corticosteroid therapy is rarely beneficial. Our case of MAR is noteworthy because it involved a woman, was associated with an uveitis, and improved with corticosteroid therapy.
