Intraoperative radiotherapy is a high precision technique that allows to administer a single dose of irradiation directly during a surgical act:
- As a dose of overprint: on the residue or zone at risk of relapse,
- After surgical exposure in case of unresectable tumors.
Advantages: direct visualization of the bed to be irradiated, rejecting healthy tissues outside the field, avoiding unnecessary irradiation.
Special interest has the RIO program in: Breast cancer, applying:
- Single dose: Completely suppress external irradiation (6-7 weeks).
- Overprint Dose: Shorten external irradiation.
- Mastectomy with preservation of Areola-nipple complex: after mastectomy, the areola / nipple complex is preserved, which is irradiated intraoperatively with immediate reconstruction of the mammary gland. The only center that does it.
- Pelvic tumors (cancer of the rectum, sarcomas, gynecological).
- As overprint of the surgical bed after preoperative radiotherapy in carcinoma of the lung, thyroid, pancreas and gynecology.
