Biochemical changes of the human semen produced by chlorambucil, testosterone propionate and human chorionic gonadotropin administration.

Biochemical analysis and morphological studies were carried out in six patients with lymphomas during and after withdrawal treatment with chlorambucil, testosterone propionate (TP) and human chorionic gonadotropins (HCG). In the course of the treatment with chlorambucil patients developed severe oligozoospermia or azoospermia. The spermatogenesis recovered after a variable period of time following suspension of treatment. During the drug administration seminal fructose and citric acid concentrations increase but the recovery after withdrawal takes a longer period of time. Simultaneous treatment with HCG or TP normalized the biochemical parameters without restoring spermatogenesis.

Combined cyclophosphamide vincristine, procarbazine, and prednisone (COPP) therapy of malignant lymphoma. Evaluation of 190 patients.

One hundred ninety patients who had advanced active Hodgkin's disease, lymphosarcoma, or reticulum cell sarcoma were treated with a combination of cyclophosphamide, vincristine, procarbazine, and prednisone (COPP) given in a cyclical fashion every month. Complete remission was produced in 91 of 138 (66%) patients with Hodgkin's disease and in 39 of 52 (75%) patients with non-Hodgkin's lymphoma (lymphosarcoma and reticulum cell sarcoma). The response rate was higher in patients who completed six cycles of therapy compared to those who completed only three to five cycles: 77% vs. 45%, respectively, in Hodgkin's disease, and 85% vs. 46%, respectively, in non-Hodgkin's lymphoma. The median duration of remission was longer for Hodgkin's disease patients who completed six cycles (30 months vs. 10 months). The median duration of complete remission of non-Hodgkin's lymphoma was 14 months. The response to treatment correlated positively with survival. The median survival time start of COPP treatment for patients with Hodgkin's disease was 7 months for nonresponders, 14 months for those who attained partial remission, and more than 48 months for those who attained complete remission. For patients with non-Hodgkin's lymphoma, the median survival time from start of COPP treatment was 24 months for nonresponders and those who had partial remission, and more than 32 months for those who attained complete remission. Of complete remission responders with Hodgkin's disease, 70% are still alive 84 months after diagnosis, and 63% of the patients witn non-Hodgkin's lymphoma are still alive 48 months after diagnosis.
