The combined radiation and hormonal therapy of prostatic carcinoma: a conceptual analysis

The combined radiation and hormonal therapy of prostatic carcinoma: a conceptual analysis

Strahlentherapie und Onkologie 167(9): 523-529

The concept of a combination of radiotherapy and hormonal therapy for the treatment of locally advanced carcinoma of the prostate was evaluated in view of an improved success rate compared to radiotherapy alone. At present, however, radiotherapy still remains the central mode of therapy in the treatment of the local tumor. The time sequence in a combination with hormonal therapy is of importance. Antecedent hormonal treatment can reduce tumor size, thus improving local conditions for percutaneous--and especially interstitial--radiotherapy; it is indicated in patients with voiding problems. An improvement in survival rates has so far not been achieved, however, local tumor remission rates are better. With concomitant hormonal therapy, compared to radiotherapy alone, tumor progression rates are lower. It remains to be seen, whether these results can be improved by using newer pharmacological ways of androgen blockade. The application of androgen withdrawal as a secondary measure with local tumor persistence or progression after radiotherapy remains a palliative treatment of limited efficacy. Due to the heterogeneity of the available study reports and the concurrent lack of controlled, randomized trials, a conclusive evaluation of the concept of combined radio- and hormonal therapy of prostatic cancer is as yet not possible.
