Follow-up after radiotherapy : how and why?

radiotherapy tolerance tests

SHORT VERSION

After radiation therapy, patients are regularly followed by the treating physician and radiation oncologist for 5 to 10 years.

The follow-up after radiotherapy is very important. It is ensured by the radiation oncologist and the treating physician. This follow-up will be regular and for up to 5-10 years.. Its length depends on the cancer type and radiotherapy type received by the patient. The objective is to control that the treatment is well toleratedandthat the patient does not develop disabling late side effects, especially late side effects It should be kept in mind that acute toxicities (e.g. fatigue, skin reddening) are unavoidable, but will disappear rapidly when the treatment is stopped. During this follow-up, the physicians also evaluate the treatment effectivenessby physical examination, laboratory tests (results of a blood test), or imaging (CT, MRI, ultrasonography, or positron emission tomography, PET). These follow-up consultations also are an important time for discussionbetween patient and doctor.

FIRST TESTS TO PREDICT A PATIENT’S RADIOSENSITIVITY

NovaGray develops and commercializes the first radiotherapy tolerance tests for patients treated for breast or prostate cancer.

Performed before the start of radiotherapy with a simple blood draw, the tests assess the patients’ individual radiosensitivity and determine their risk of developing late complications after radiotherapy.

WHY DO A RADIOSENSITIVITY TEST?

Knowing a patient’s individual radiosensitivity is important information that can help:

  • Reassure the patient in preparation for radiotherapy
  • Guide physicians in choosing the most appropriate treatment plan
  • Adapt patient follow-up after radiotherapy

Team NovaGray

NovaGray develops radiotherapy tolerance tests for breast and prostate cancer patients. NovaGray's mission is to help personalize cancer treatment by assessing each patient's individual sensitivity before starting radiotherapy. NovaGray technology has been validated by multi-center prospective clinical trials. NovaGray tests are recommended by the French Society of Radiation Oncology (SFRO).
