Trial Identification

Brief Title: Hypofractionated Palliative Radiotherapy in Patients With Advanced Non-operable Rectal Cancer

Official Title: Palliative Hypofractionated Radiotherapy in Non-operable Rectal Cancer: A Retrospective Study

Study ID: NCT03853733

Conditions

Rectal Cancer

Interventions

rectal cancer radiotherapy

Study Description

Brief Summary: Many patients with rectal cancer were not candidates for surgical resection because advanced age, comorbidities, or multiple synchronous metastases. In this scenario only comfort measures or different palliative radiotherapy regimens are applied, from single doses to treatments lasting several weeks. The aim of this prospective study is to describe the preliminary results of our protocol of hypofractionated palliative radiotherapy in patients with non-operable rectal cancer.

Detailed Description: Many patients with rectal cancer were not candidates for surgical resection because advanced age, comorbidities, or multiple synchronous metastases. In this scenario only comfort measures or different palliative radiotherapy regimens are applied, from single doses to treatments lasting several weeks. The aim of this prospective study is to describe the preliminary results of our protocol of hypofractionated palliative radiotherapy in patients with non-operable rectal cancer. Patients with rectal cancer who were not candidates for surgical resection because advanced age, comorbidities, or multiple synchronous metastases at the time of diagnosis were considered eligible. Patients were immobilized in the prone position with a belly-board in order to reduce small bowel irradiation. To limit organ motion patient were instructed to empty the bladder and drink 500cm3 of water 45-60 minutes before CT simulation and before every treatment fraction. A conformal three-dimensional radiotherapy technique was planned to deliver to the primary tumor and the enlarged pelvic nodes a total dose of 39Gy in 13 sessions of 3Gy in 17 days. Symptomatic response after the end of treatment has been measured for bleeding and pain and acute toxicity were reported according to CTCAEv4.0 scale.
