The aim of this study is to investigate the effect of ATRA (Vesanoid) and the effect of tailored radiotherapy in patients with squamous cell carcinoma of the oropharynx, larynx or hypopharynx.

The investigators propose a randomized controlled trial to develop and evaluate the impact of promoting advice on diet and lifestyle recommendations for cancer prevention at colorectal cancer screening among individuals who may be at higher risk for colorectal cancer (CRC). The specific objectives of this study are to 1) develop a lifestyle intervention based on evidenced-based diet and lifestyle recommendations (i.e. those proposed by the World Cancer Research Fund (WCRF) and the French National Cancer Institute); 2) evaluate the effect of the intervention on the adherence to the target diet and lifestyle recommendations as well as other subjective health measures, including quality of life; 3) evaluate the effect of the intervention on anthropometrics.

Testicular germ cell tumor (TGCT) is the most common malignancy in men between 15 and 40 years. Although TCGT survivors have a good survival prognosis, they suffer from short- and long-term sequelae such as chronic fatigue, psychological disorders, cardiovascular toxicities and second malignancies. The benefits of physical activity (PA) during treatments have been demonstrated in cancer patients to improve quality of life (QoL) and physical fitness and to reduce fatigue. However, few PA programs have been proposed to TGCT patients and their effects on sequelae have not been assessed yet. A growing body of evidence links treatment-related alteration in the gut microbiota to sequelae of cancer survivors, including fatigue and cardiovascular toxicities. Also, PA has been known as a possible modulator of the gut microbiota composition. To date, no study has been conducted to examine how the gut microbiota and its metabolites moderate the effect of PA on fatigue and other late effects in TGCT survivors. The objectives will be to assess the impact of a PA program on fatigue and other sequelae and to investigate how the gut microbiota and its metabolites moderate the associations between PA and sequelae. We will conduct a prospective, multicenter, phase III, randomized controlled trial of a one-year supervised PA program. 236 men with metastatic TGCT and eligible for a first line of chemotherapy will be randomly assigned to either PA intervention or control arm. All patients will benefit from a connected activity tracker and PA recommendations. In the intervention arm, PA will be based on supervised sessions and motivational interviews. The primary endpoint (fatigue) will be assessed at 3 years. The trial will provide novel insights into the impact of PA on fatigue and other sequelae in TGCT survivors with understanding a potential underlying mechanism of gut microbiota. This evidence will support the development of targeted PA guidelines to improve QoL and reduce sequelae in TGCT survivors.
