Interstitial pneumonitis related to flutamide monotherapy for prostate cancer

INTERNATIONAL JOURNAL OF UROLOGY, Issue 9 2004

Abstract A 88-year-old man with prostate cancer was receiving non-steroidal anti-androgen therapy (flutamide, 375 mg/day). Three weeks after starting therapy, the patient developed dyspnea and bilateral pulmonary interstitial infiltrates. The withdrawal of flutamide and the initiation of steroid therapy resulted in clinical improvement. [source]

Neoadjuvant flutamide monotherapy for locally confined prostate cancer

Abstract Background: We compared the clinical effects and impact on quality of life (QOL) of patients who received a 3-month course of flutamide monotherapy before radical prostatectomy with those who received a 3-month course of luteinizing hormone-releasing hormone (LHRH) agonist monotherapy. Methods: Thirty-seven patients with non-metastatic prostate cancer were enrolled in this study (19, flutamide; 18, LHRH agonist). The rates of change of serum prostate-specific antigen (PSA) and testosterone levels, downsizing of prostate volume, the rate of organ confined disease, adverse effects and perioperative scores measured using the European Organization for Research and Treatment of Cancer Prostate Cancer Quality of Life Questionnaire (EORTC-P) and the Sapporo Medical University Sexual Function Questionnaire (SMUF) were analyzed. Results: At radical prostatectomy, pathological variables were not significantly different in the two groups. Serum testosterone level was significantly higher (mean 359.2 compared to 10.5, P < 0.001), complete response rate of PSA (13% compared to 57%, P = 0.028) and rate of downsizing of prostate volume (mean, ,17.7% compared to ,35.4%, P = 0.038) were significantly lower in the flutamide group than in the LHRH group. After neoadjuvant hormone therapy, the scores on the sexual problem domain of EORTC-P (P = 0.033) and sexual desire score of SMUF (P = 0.021) were significantly higher in the flutamide group than in the LHRH group. At a median follow-up of 34 months after prostatectomy, biochemical failure-free survival rate in the flutamide group did not differ from that in the LHRH group. Conclusion: This study suggests that flutamide monotherapy can be an acceptable modality as an option for neoadjuvant hormone therapy. [source]

Long-term outcome of antiandrogen monotherapy in advanced prostate carcinoma: 12-year results of a phase II study

BJU INTERNATIONAL, Issue 6 2003

OBJECTIVE To present the long-term outcome of patients with locally advanced or metastatic prostate carcinoma treated by first-line antiandrogen monotherapy. PATIENTS AND METHODS From 1983 to 1990, 41 patients with advanced prostate carcinoma were treated with flutamide monotherapy until progression or the appearance of toxicity. Twenty-five patients (61%) had T3-T4N0M0 and 16 (39%) T2,4N0,3M1 prostate carcinoma. Consensus criteria were adopted to evaluate the response. Plasma testosterone and sexual function were recorded for the first 3 years. RESULTS Flutamide was administered for up to 147 months; seven patients (17%) interrupted the treatment because of toxicity. There was an objective response in 17 (41%) patients; 20 (49%) had stable disease while four (10%) progressed. There were objective responses, lasting up to 150 months, in 82% of those with M0 and in 18% with M1 disease (P = 0.05). The median time to progression in patients with an objective response and stable disease was 45 and 16 months, respectively (P < 0.001). Thirty-one patients (76%) died from prostate cancer and 10 (24%) from unrelated diseases. The median survival was 67 and 36 months in patients with an objective response and stable disease, respectively (P < 0.001). There was an improvement in performance status in 85% and reduction in bone pain in 83% of the patients; sexual activity was maintained in 63%. CONCLUSION Monotherapy with flutamide is well tolerated. Objective responses are more frequent in patients with locally advanced disease. Patients with an objective response within 6 months have a prolonged progression-free and overall survival. [source]
