Scarce data investigate the impact of radiotherapy (RT) on biology markers. An analysis of ancillary study of RIT (Radiation Impact on Thromboembolic events) prospective trial was carried out. All patients with non-metastatic solid tumors and treated with radiotherapy and/or brachytherapy in curative and consenting to have blood samples were included. A significant decrease in white blood count, (i.e. lymphocytes, monocytes, neutrophils and basophils) and platelet counts was observed after RT and maintained at 6 months. Whereas, eosinophils, D-dimers and hemoglobin levels were affected respectively 3 months and 6 months after RT initiation. Conversely, red cells count and CRP level were not affected by RT. This study is an advocacy to develop an understanding of basic immune system in relation with RT.

Coronavirus disease outbreak has affected all aspect of clinical care including cancer clinical trials. To minimize exposure of frail cancer patients, an implementation of telemedicine was retained. The impact of this implementation on primary and secondary endpoints criteria of ongoing clinical trials was analyzed. Out of 128 oncology clinical trials, 25 (19%) had an implementation of teleconsultation. Poor data reporting induced mainly a bias on qualitative and descriptive primary endpoints than those assessing efficacy (80% vs 20%; p < 0.001). The integration of telemedicine and E-technologies in the medical practices and clinical trials must be designed and validated.
