Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

There is no randomized controlled trial (RCT) comparing Conformal Radiotherapy (3DCRT) versus the Intensity Modulated Radiotherapy (IMRT) in terms of toxicity and disease control. Data from retrospective studies show that IMRT reduces the risk of severe late complications. More recently, the results from the RTOG 0126 study have also confirmed the benefit from IMRT in reducing acute toxicity for prostate cancer treated with conventional dose escalation. Therefore, to investigate the real clinical benefit of the IMRT over 3DCRT using a hypofractionated schedule in prostate cancer, the investigators developed a RCT.

IMRT- Hypofractionated schedule 70 Gy/25 fx

The IMRT plan consisted of five - seven fields to deliver the same dose prescribed at the isodose line covering 95% of PTV.By the linear-quadratic formula, considering an α/β ratio of 1.5 Gy for prostate cancer, 70 Gy/25 fractions is equivalent to 86 Gy in 43 fractions of 2 Gy. All patients were simulated on CT simulator.

Group Type EXPERIMENTAL

IMRT

Intervention Type RADIATION

The IMRT plan consisted of five - seven fields to deliver the same dose prescribed at the isodose line covering 95% of PTV.

The 3DCRT plan consisted of six fields to deliver a total dose of 70 Gy/ 25 fractions of a single daily dose of 2.8 Gy.

3DCRT-Hypofractionated schedule 70 Gy/25 fx

The 3DCRT plan consisted of six fields to deliver a total dose of 70 Gy/ 25 fractions of a single daily dose of 2.8 Gy. By the linear-quadratic formula, considering an α/β ratio of 1.5 Gy for prostate cancer, 70 Gy/25 fractions is equivalent to 86 Gy in 43 fractions of 2 Gy. All patients were simulated on CT simulator.
