Experimenteel: 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.

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.

Gastrointestinal and geniturinary acute toxicity
Tijdsspanne: 6 months
|
The primary study outcome was acute treatment reactions from the beginning of treatment to 6 months after the end of treatment.
Patients were seen weekly, or as required, during treatment by a radiation oncologist.
Acute gastrointestinal (GI) and genitourinary (GU) toxicity were prospectively assessed and graded according to the Radiation Therapy Oncology Group scoring system for the rectum and bladder.

6 months

|
Gastrointestinal and geniturinary late toxicity
Tijdsspanne: 24 months
|
Any toxicity developed after 6 months from radiotherapy treatment was considered as late toxicity.
Late gastrointestinal (GI) and genitourinary (GU) toxicity were prospectively assessed and graded according to the Radiation Therapy Oncology Group scoring system for the rectum and bladder.
