When to stop immunotherapy for advanced melanoma: the emulated target trials.

Background: Immune checkpoint inhibitors (ICIs) have demonstrated their efficacy with a 7.5-year overall survival (OS) close to 50% for advanced stages. The design of clinical trials provides for treatment until progression or toxicity, or for a maximum duration of two years.

Methods of nivolumab administration in advanced melanoma: A comparison of patients' clinical outcomes treated with flat dose or weight-adjusted dose, a multicenter observational study.

Background: Nivolumab obtained approval in advanced melanoma (AM) with weight-adjusted dose (WAD) administration (3 mg/kg/2 weeks). In 2018, the dosage regimen was changed to flat dose (FD) administration (240 mg/2 weeks or 480 mg/4 weeks) based on a modeling study, without clinical data.

Methods: AM patients have been prospectively included in the French national multicenter MelBase database since 2013.

The efficacy and safety of first-line metastatic melanoma treatment with ipilimumab + nivolumab versus nivolumab in a real-world setting.

Background: The Checkmate 067 randomized controlled trial, published in 2015, demonstrated improved progression-free survival and numerically, although not statistically, superior overall survival for ipilimumab + nivolumab. The objective of this study was to compare the efficacy and safety of nivolumab to ipilimumab + nivolumab as first-line treatment for metastatic melanoma in a real-world setting.

Methods: Patients were prospectively included in the French Melbase cohort from 2013 to 2022.

Radiotherapy and prognostic factors in adnexal carcinomas: A retrospective study of 657 patients from the French CARADERM network.

Background: Cutaneous adnexal carcinomas are a heterogeneous group of rare neoplasms. Surgical excision is the first-line treatment in localized stage. The use and effectiveness of radiotherapy have not been thoroughly evaluated in these neoplasms.

Combined Nivolumab and Ipilimumab in Octogenarian and Nonagenarian Melanoma Patients.

Data regarding elderly melanoma patients treated with anti-PD-1 or anti-CTLA-4 antibodies are in favor of tolerability outcomes that are similar to those of younger counterparts. However, there are very few studies focusing on elderly patients receiving nivolumab combined with ipilimumab (NIVO + IPI). Here, we ask what are the current prescribing patterns of NIVO + IPI in the very elderly population and analyze the tolerance profile.

Cost-Effectiveness Analysis of Sequential Treatment Strategies for Advanced Melanoma in Real Life in France.

Nine drugs have been marketed for 10 years for the treatment of advanced melanoma (AM). With half of patients reaching a second line, the optimal sequence of treatments remains unclear. To inform policy-makers about their efficiency, we performed a cost-effectiveness analysis of sequential strategies in clinical practice in France, for BRAF-mutated and wild-type patients.

Impact of systemic therapies in metastatic melanoma of unknown primary: A study from MELBASE, a French multicentric prospective cohort.

Background: Clinical outcomes of advanced melanoma of unknown primary (MUP) in the era of novel therapies have been scarcely studied.

Objective: To investigate the efficacy and safety of systemic treatments in patients with advanced MUP compared to patients with stage-matched melanoma of known cutaneous primary (cMKP).

Methods: Based on the nationwide MelBase prospective database, this study included advanced melanoma patients treated from March 2013 to June 2021 with first-line immunotherapies, targeted therapies, or chemotherapy.

Non-V600E/K BRAF Mutations in Metastatic Melanoma: Molecular Description, Frequency, and Effectiveness of Targeted Therapy in a Large National Cohort.

Purpose: Mitogen-activating protein kinase inhibitors (MAPKis) are largely used in V600E/K BRAF-mutated metastatic melanomas, but data regarding effectiveness of targeted therapy in patients with rare BRAF mutations and molecular description of these infrequent mutations are scarce.

Patients And Methods: A multicenter study was conducted on patients with metastatic melanoma harboring a well-identified mutation of BRAF and enrolled from March 2013 to June 2021 in the French nationwide prospective cohort MelBase. The molecular BRAF mutation pattern, response to MAPKis when applicable, and survival data were analyzed.

Histological Features Associated With Human Mpox Virus Infection in 2022 Outbreak in a Nonendemic Country.

Skin histology of papules and pustules from 5 men having sex with men with mpox infection showed viral intracytoplasmic cytopathic changes, interface dermatitis, marked inflammatory dermic infiltrate including superficial neutrophils and perivascular and periadnexal deep lymphocytes. Histologic description of mpox lesions improves our understanding about clinical presentations and may have some therapeutic implications.

Risk of irAEs in patients with autoimmune diseases treated by immune checkpoint inhibitors for stage III or IV melanoma: results from a matched case-control study.

Objective: To quantify the risk of immune-related adverse events (irAEs) in patients with pre-existing autoimmune disease (pAID) treated by immune checkpoint inhibitors (ICIs) for stage III or IV melanoma.

Methods: Case-control study performed on a French multicentric prospective cohort of patients with melanoma, matched for irAE risk factors and oncological staging. Risk of irAE was assessed by logistic regression.

[Marjolin ulcers after cultured epidermal autograft in severely burned patients: a rare case series and literature review].

The advent of tissue engineering and the clinical applications with cultured epidermal autograft (CEA) have improved the prognosis of severely burned patients. Marjolin ulcers (MUs) are a well-known complication of burns. These malignant neoplasm transformations of burn scars are usually squamous cell carcinomas with a higher incidence of regional metastases.

Tolerance and Effectiveness of Targeted Therapies in Aged Patients with Metastatic Melanoma.

Purpose: Melanoma's incidence is increasing, and elderly people could be significantly impacted since the majority occurs in people over 65 years of age. Combined BRAF and MEK targeted therapies (TT) are current standard regimen for BRAF mutated metastatic melanoma (MM). Except for subgroups of pivotal trials, little data are available for TT in this population.

Late-onset adverse events of anti-PD1 therapy in melanoma patients: An observational study from MELBASE, a nationwide prospective cohort.

Background: Late-onset adverse events (AEs) of anti-programmed cell death 1 (anti-PD1) antibodies have not been systematically described.

Objectives: The purpose was to evaluate late-onset AEs in melanoma patients treated with anti-PD1 administered for at least 2 years in a real-life setting.

Methods: Patients were screened from MelBase, a French multicentric biobank dedicated to the prospective follow up of unresectable stage III or IV melanoma.

Treatment strategies and safety of rechallenge in the setting of immune checkpoint inhibitors-related myositis: a national multicentre study.

Objectives: The occurrence of immune-related myositis (irM) is increasing, yet there are no therapeutic guidelines. We sought to analyse the current therapeutic strategies of irM and evaluate the outcomes of immune checkpoint inhibitors (ICIs) rechallenge.

Methods: We conducted a nationwide retrospective study between April 2018 and March 2020 including irM without myocardial involvement.
