Impact of a Melatonin Supplementation on the Quality of Life in Elderly Metastatic Cancer Patients

Impact of a Melatonin Supplementation on the Quality of Life in Elderly Metastatic Cancer Patients (> = 70 Years) - PHRC-K13-170

Melatonin may represent an effective complementary treatment to standard anticancer treatments in order to reduce asthenia, depression, sleep disturbances, cognitive impairment and performance status as part of quality of life. Moreover, melatonin has been evaluated in several clinical trials in cancer patients with no side effects. It could be particularly of interest in elderly cancer patients as they exhibit a significant deficiency of melatonin production .

The investigators propose to perform a prospective and randomized study to study the effect of a melatonin supplementation on the quality of life of elderly advanced/metastatic cancer patients (age ≥ 70) treated for a locally advanced or metastatic cancer.

Inclusion Criteria:

• Age > = 70 years.
• Performance status < = 2 (WHO criteria)
• Life expectancy > 3months
• A patient with solid tumor locally advanced or metastatic
• Indication of systemic anticancer treatment : oral or IV chemotherapy, endocrine therapy, target therapy or immunotherapy
• MMS-orientation ≥ 7 (geriatric Mini Mental State face-to-face questionnaire)
• Able to swallow and retain oral treatment
• Patient who signed the participation consent before entering the trial
• Patient able to read, write and understand French.

• Unability to fill out questionnaires
• melatonin treatment ongoing or completed for less than 3 months
• Treatment with an investigational drug, participation to another therapeutic clinical trial within <30 days
• Hypersensitivity to melatonin or any of the excipients
