[Results of surgical and radiotherapy of prostatic cancer T1-4N0-1M0].
To compare the results of radical prostatectomy and conformal radiotherapy in prostatic cancer T1-4N0-1M0, we made a retrospective study of 306 patients with prostatic cancer T1-4N0-1M0 of whom 144 (47.1%) were treated surgically (radical prostatectomy) while 162 (52.9%) were exposed to extracorporeal conformic radiotherapy. Follow-up median was 30.7 +/- 29.8 months. Five and 10-year overall, specific and PSA recurrence free survival in 306 patients was 94.0% and 90.1% (median was not achieved), 96.6% and 94.3% (median was not achieved), 66.1 and 49.2% (median was 84.0 +/- 4.4 months). In multifactorial analysis significant prognostic factors of PSA recurrence free survival were T category (p = 0.021) and Glison's sum (p = 0.002). In the subgroup of patients with local prostatic cancer there was a significant superiority of the operated patients by PSA recurrence free survival over irradiated group in baseline PSA < 10 ng/ ml (p = 0.015), Glison's index < 7 (p = 0.071) and combination of these factors (p = 0.018). A favourable prognosis factor of PSA recurrence free survival in operated patients was operative Glison's index < 7 (p = 0.001), among operated patients--nadir PSA < 1 ng/ ml (p = 0.003). Surgical and radiation treatment of local and locally advanced prostatic cancer provided satisfactory results. In the group of good prognosis (cT1-2N0, PSA < 10 ng/ml, Glison's sum < 7) radical prostatectomy gives advantage of PSA recurrence free survival. In patients with prostatic cancer cT > T2, N+, Glison's index > 7 and PSA > 10 ng/ml surgical treatment and remote radiotherapy are equally effective in respect to survival free of biochemical recurrence.
