Overview
Surgical excision is the treatment of choice for stage II, III and resectable stage IV melanoma and is curative in most cases. Given the recent success of immunotherapy for the treatment of patients with advanced metastatic melanoma, the use of immunotherapy has been evaluated in the adjuvant setting for patients at high risk of recurrence. In this context, Nivolumab prolonged Recurrence-Free Survival (RFS) while reducing toxicity compared with Ipilimumab in a phase III clinical trial, and was subsequently FDA-approved in December 2017 for adjuvant treatment of locally advanced melanoma with metastatic lymph node involvement after resection of cutaneous lesions. While a fraction of patients benefit from adjuvant PD-1 immunotherapy, approximately 40% of patients are still relapsing despite this adjuvant treatment, without being able to identify them early and with poor understanding of resistance mechanisms. Additionally, about 15% of the patients will develop serious adverse effects driven by immunotherapy and often discontinuing or even contraindicating the onset of subsequent treatments, hence affecting global patients care. It is therefore of prime importance to identify clinical features able to predict response and toxicities to adjuvant immunotherapy in melanoma.
Interventions
- Other Frequency and duration of response to adjuvant immunotherapy according to clinical features
* Frequency of relapse to adjuvant immunotherapy according to clinical features * Duration of relapse as defined by the time (days) between adjuvant immunotherapy onset and relapse date according to clinical features - Other Frequency of each type of relapse (i. e. local, distant, unique or multiple) to adjuvant therapy according to clinical features
Percentages of each type of relapse (i. e. local, distant, unique or multiple) according to clinical features - Other Duration of relapse-free survival according to clinical features
Duration of relapse-free survival as defined by the time (days) between adjuvant immunotherapy onset and relapse date. - Other Duration of overall survival according to clinical features
Duration of relapse-free survival as defined by the time (days) between adjuvant immunotherapy onset and the date of death (irrespectively of the cause) 10 years after inclusion in the study. Alive or lost to follow-up patients will be censored at the date of the last follow-up visit. - Other Overall response rate
Response rate to adjuvant immunotherapy and to treatment lines subsequent to relapse. Response rate to adjuvant immunotherapy is defined by the absence of relapse as assessed by the physician following the first year of adjuvant therapy. Response to treatment after relapse is defined as partial or complete response as assessed by the physician following the first year of adjuvant therapy. - Other Frequency of adverse events according to clinical features
Rate of adverse events according to their nature and grade (as defined by CTCAE V 5.0) and according to clinical features
Primary outcome measures
- Duration of response to adjuvant immunotherapy according to clinical features. [Time frame: 1 year]
