“Radiobiology through the eyes of radiation oncologists”

Date: February 24th – May 12th 2026

Time: scheduled weekly on Tuesdays, 7 pm (CET)

The course aims to provide training for radiation oncologists, clinical oncologists, and medical physicists in Ukraine during the war, equipping participants with a basic understanding of the molecular basis of radiation effects on tumors and normal tissues through the lens of clinical practice. We will discuss the systemic and delayed effects of radiotherapy on tumor and normal tissue biology, the biological basis of radiotherapy fractionation, and the modeling of radiobiological response.

The course will provide an up-to-date overview of the distinct biological effects resulting from the radiotherapy of different qualities (photon vs. particle irradiation) and different dose rates (FLASH vs. conventional radiotherapy), and the insights into the therapeutic potential of combining radiotherapy with other types of conventional and innovative treatments, including chemotherapy, immunotherapy, hormone therapy, and thermotherapy.

We will review recent updates on the biology of tumor re-irradiation and recurrence, as well as the effect of circadian rhythms on treatment effectiveness and normal tissue toxicity.

By the end of the course, participants will have acquired a basic understanding of how analyzing tumor biology can be leveraged to personalize radiation therapy and enhance treatment outcomes.

The target audience includes radiation oncologists, clinical oncologists, and medical physicists seeking to deepen their understanding of the radiobiological basis of radiotherapy and potentially apply radiobiological principles in their clinical practice. Additionally, this course can be of interest to PhD candidates and postdoctoral researchers across various biological fields who aim to integrate radiobiological insights into their research.
