Hormonal treatment of advanced breast cancer. A randomized trial of tamoxifen versus nandrolone decanoate.
The response to tamoxifen (TAM) (10 mg to 20 mg twice orally) was compared with the response to nandrolone decanoate (NAN) (50 mg every second week or 100 mg every third week intramuscularly) in this randomized study in previously untreated women with advanced breast cancer. Patients were postmenopausal or postmenopause was induced with irradiation therapy. The two treatment groups were highly similar in different patient characteristics. Of 67 evaluable patients treated with TAM, ten (15%) had a complete or partial remission, 28 (42%) had stabilized disease and 29 (43%) had progressive disease. In the 60 patients treated with NAN, the figures were ten (17%), 22 (37%) and 28 (47%) respectively. The response rates did not differ significantly. Tam was as good as NAN in osseous metastases. Four of 34 patients responded to TAM and three of 38 patients responded to NAN. NAN had a tendency for better response in the treatment of visceral metastases. Six (43%) of 14 patients responded to NAN while only three (14%) of 21 responded to TAM (P = 0.11). The median duration of remission was 24 months in the TAM arm and 17 months in NAN (insignificant). As second line treatment, NAN after TAM gave one complete remission and three partial remissions, but none responded to TAM after NAN. The side-effects of both drugs were rare and mild. These data indicate that TAM and NAN are comparable in the treatment of advanced breast cancer.
