Early Biomarkers of Tumor Response in High Dose Hypofractionated Radiotherapy Word Package 3 : Immune Response

Not Applicable

Terminated

• Conditions: Kidney Neoplasms; Colorectal Neoplasms; Carcinoma, Hepatocellular; Melanoma

• Registration Number: NCT02439008
• Lead Sponsor: Centre Oscar Lambret

Brief Summary

This study will follow-up immune cell populations, secreted factors and released nanovesicles in the blood before, during and after high dose radiation therapy which should give new information of the efficacy of the hypofractionated high dose radiation therapy and a rationale for adjuvant immunotherapy.

Detailed Description

* Patient information and collection of a signed informed consent form

* Clinical data collection

* Blood samples of 35 mL:

1. after registration, prior to the first fraction of radiotherapy

2. within 15 minutes after the administration of the 1st, the 2nd and the 3rd radiotherapy sessions

3. one week, 3 months, 6 months, 9 months and 12 months after the last radiotherapy session

* Storage of the blood samples at ambient temperature

* Transportation of the samples to the Institute of Biology of Lille (IBL) - CNRS UMR8161 for analysis

* Destruction of the samples at the end of the analysis
