Adjuvant melatonin for the prevention of recurrence and mortality following lung cancer resection (AMPLCaRe): A randomized placebo controlled clinical trial
Notice bibliographique
Résumé
BackgroundDespite curative intent resection in patients with non-small cell lung cancer (NSCLC), recurrence leading to mortality remains too common. Melatonin has shown promise for the treatment of patients with lung cancer; however, its effect following cancer resection has not been studied. We evaluated if melatonin taken after complete resection reduces lung cancer recurrence and mortality, or impacts quality of life (QOL), symptomatology or immune function.MethodsParticipants received melatonin (20 mg) or placebo nightly for one year following surgical resection of primary NSCLC. The primary outcome was two-year disease-free survival (DFS). Secondary outcomes included five-year DFS, adverse events, QOL, fatigue, sleep, depression, anxiety, pain, and biomarkers assessing for immune function/inflammation. This study is registered at https://clinicaltrials.gov NCT00668707.Findings709 patients across eight centres were randomized to melatonin (n = 356) versus placebo (n = 353). At two years, melatonin showed a relative risk of 1·01 (95% CI 0·83–1·22), p = 0·94 for DFS. At five years, melatonin showed a hazard ratio of 0·97 (95% CI 0·86–1·09), p = 0·84 for DFS. When stratified by cancer stage (I/II and III/IV), a hazard reduction of 25% (HR 0·75, 95% CI 0·61–0·92, p = 0·005) in five-year DFS was seen for participants in the treatment arm with advanced cancer (stage III/IV). No meaningful differences were seen in any other outcomes.InterpretationAdjuvant melatonin following resection of NSCLC does not affect DFS for patients with resected early stage NSCLC, yet may increase DFS in patients with late stage disease. Further study is needed to confirm this positive result. No beneficial effects were seen in QOL, symptoms, or immune function.FundingThis study was funded by the Lotte and John Hecht Memorial Foundation and the Gateway for Cancer Research Foundation.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Apprise à partir de 10 348 étiquettes directes de Codex et de 10 348 étiquettes directes de Gemma. Le mode candidate est l'union des têtes enseignantes seuillées; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont ni des étiquettes humaines ni des étiquettes directes de modèles de pointe.
