Abstract

PURPOSE:

To analyze survival and complications in high dose 3D conformal radiotherapy (3DCRT) patients treated with curative and post-operative intent and compare radical surgery + radiotherapy (RT) patients vs. RT only patients.

MATERIAL AND METHOD:

103 patients were treated curatively (RAD), 94 postoperatively (POST-OP). The mean age was higher in RAD group (72.6 years, range 56.4-85.1) than in POST-OP group (65.4 years, 43.9-77) (p < 0.0001). According to NCCN prognostic classification 13 (12%) patients was low risk, 48 (47%) intermediate risk and 42 (41%) high risk in RAD group. In POST-OP group 13 (14%) patients were low risk, 37 (40%) intermediate risk and 44 (46%) high risk. Hormone Therapy (HT) was administered in 98 patients (95%) in RAD and in 45 patients (47.8%) in POST-OP. Patients were treated with a three-dimensional conformal radiotherapy (3D-CRT). In RAD 15 (15%) were alive with disease (AWD), 5 (5%) dead of disease (DOD) and 10 (10%) dead of other cause (DOC); in POST-OP 14 (14.8%) were AWD, 2 (2%) DOD and 3 (3%) DOC. The prescription dose was 80 Gy in 2-Gy fractions in the RAD group, and 70 Gy in 2-Gy fractions in the POST-OP, respectively.

RESULTS:

No biochemical or clinical relapse was found in low risk patients in RAD group and 1 relapse in POST-OP group. The largest number of relapses occurred and in intermediate-high risk in RAD (39%) and POST-OP group (33%). In the cause-specific survival analysis no significant differences were found in high risk group between RAD and POST-OP (p = 0.9). In the biochemical relapse-free survival (bRFS) at 5 years analysis no significant differences were found in the high risk group between RAD and POST-OP (p = 0.1020).

CONCLUSION:

RT in RAD low- risk is very effectiva. RAD and POST-OP RT were well tolerated with a very low toxicity. The cause-specific survival at 5 years was 95% and 97% for the two groups of treatment, RAD and POST-OP respectively (Log-rank test p = 0.2908).
