Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary objective of this study is to evaluate the prediction of late toxicity by the radiation induced CD8 T-lymphocyte apoptosis

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The two cancer sites concerned by this trial are intermediate risk prostate cancer treated with conformational radiotherapy with or without intensity modulation, and breast cancer patients treated with adjuvant radiotherapy after breast conservative surgery for patients aged under 60 years of age. The identification of 5% of patients at risk of severe toxicity should allow to deliver high dose radiotherapy among 95% of patients with a lower risk of severe late complications.
