[Objective and subjective response in stage D2 prostate cancer patients with cancer pain].
Fourty-eight patients with stage D2 prostate cancer, initially treated with endocrine therapy at the University of Tokyo between 1981 and 1990, were followed up and analysed. For the assessment of a subjective response, pain score, narcotic score, and performance stages (PS) were used. Of the fourty-eight patients, twenty-one suffered from cancer pain due to bone metastases. These patients showed significantly (p < 0.01) more lesions of bone metastases and higher PS, compared with patients without cancer pain. The progression free survival of these patients was significantly (p < 0.01) lower than that of patients without cancer pain, although the actuarial survival was not significant. In twenty-one patients with cancer pain, the objective and subjective response rates to endocrine therapy were 75% and 86%, respectively. The duration of pain relief was 1.25-54 (median 19) months. Those rates to anti-cancer chemotherapy in refractory patients (8 patients) previously treated with endocrine therapy were both 25% and those to additional administration of flutamide (FUL) or diethylstilbestrol (DES) in refractory patients (6 patients) were 33% and 100%, respectively. Although the duration of pain relief was 0.78-8 (median 2) months, the additional administration of DES or FLU led to pain relief and improved quality of life (QOL) in all 6 patients. Endocrine therapy such as LH-RH agonist and non-steroidal pure anti-androgen, which has no severe side effects, would be of great usefulness in stage D2 prostatic cancer patients with pain on the basis of efficacy and safety.(ABSTRACT TRUNCATED AT 250 WORDS)
