[Prostate carcinoma: determination of progression following high-voltage therapy (author's transl)].
The fourth report of our long-term study concerns 70 cases of primary radiotherapy. The side effects of our radiation technique are minimal and temporary; in over 80% of the cases, potency was not affected. The morphologically demonstrable changes in the tumor tissue, in the original glandular parenchyma, and in the fibromuscular stroma leading to the vessels following high-voltage therapy are described. Three types of progressive patterns, based on the grade of histologic regression, can be determined. In more than half of the cases, with increasing distance from the source of radiation, no tumor or only minimal residual tumor was demonstrable. Sensibility and resistance of carcinoma of the prostate are not dependent upon the grade of differentiation of the tumor. A prognostic statement concerning the success of radiation therapy from initial histologic findings is not possible here. The occurrence of metastases in 18% of the cases following radiation probably resulted from the inexactness of the purely clinical determination of the stage of the tumor. The isolated, local treatment of prostate carcinoma through radiotherapy is justified only after exact determination of the stage of the tumor, i.e., certain exclusion of metastases via a diagnostic lymphadenectomy.
[Therapy of the carcinoma of the prostate and case control (III) (Author's transl)].
In a third information of our long-term study with now 304 cases we report on 54 cases with monotherapy-only orchiectomy, only hormones and combination of boths. With it the rectal palpable results have coincided significantly with the histological findings in all 3 therapeutic forms. As for the therapeutic result no difference is to be seen either histological or clinical after a 3 years' observation period. We cannot tell anything now about optimal methods of treatment with regard to the histological starting material. In all 3 therapeutic forms we observed regressions to stage O. The smallest plasma-testosteron concentration was found after orchiectomy, where no increase was recorded during the whole observation period.
