A phase II study of UFT, a mixture of futraful and uracil in a rate of 1:4, was performed for prostatic cancer in 5 cooperative institutions. UFT was orally administered at a daily dose of 600 mg (t.i.d.) for 4 weeks. Twenty-two patients treated with UFT were evaluated according to Koyama-Saito's criteria. Tumor staging determined by transrectal ultrasonography and other methods revealed stage B in 4 patients, stage C in 7, and stage D in 11. The overall response rate was 18.2%. Complete response was obtained in 1 patient with stage B disease, partial response in 3, minor response in 1, no change in 15, and progressive disease in 2. With respect to toxicity, anorexia was observed in 9 patients, nausea and vomiting in 8, stomatitis in 4, and diarrhea in 3. White blood cell count was less than 3,000 cells per mm3 in 1 patient, and in another case, hepatic function disorder was observed. From the results obtained, the use of UFT is TS considered desirable for prostatic cancer.

The relationships of 13 potential prognostic factors to objective response to treatment and survival time were investigated, using data gathered on 1,020 patients with advanced stage prostate cancer who have participated in the clinical trials of the National Prostatic Cancer Project. Multivariate statistical analyses revealed that previous hormone response status, analgesics, pain, elevated acid phosphatase, and anemia were the important, independent prognostic factors for objective response to treatment. For survival time, the significant prognostic factors were previous hormone response status, anorexia, elevated acid phosphatase, pain, elevated alkaline phosphatase, obstructive symptoms, tumor grade, performance status, anemia, and age at diagnosis. It is recommended that future treatment protocols for advanced stage prostate cancer take into account heterogeneity of the treatment groups with respect to these factors, either through the design of the protocol, or at the time of analysis.

Phase II study of Etoposide administered intravenously and orally was performed in 163 patients with urologic malignancies for the clinical evaluation of responses and adverse effects. The eligibility of the patients and evaluation of the responses were carried out according to the general criteria proposed by Koyama and Saito. Out of the 163 patients registered in the study, it was possible to evaluate 141. In the cases of intravenous administration, the response rates were 16.7% in testicular cancer mostly refractory to prior therapy, 15.6% in bladder cancer, 7.7% in prostatic cancer, and 0% in renal cell route. The overall response rate was 11.1%. Toxicities were noted in the gastrointestinal tract, the rates being 54.4% for anorexia, 35.4% for nausea and 17.7% for vomiting. Alopecia was observed at a high incidence of 72.1%. Myelosuppression leukopenia and thrombocytopenia were the other prominent adverse effects.

Single and combination chemotherapy was compared in a clinical trial for men with advanced, metastatic prostate cancer who had received prior pelvic irradiation and had had progression of disease despite hormonal therapy. The 149 patients were randomized to receive estramustine phosphate or cis-platinum alone or in combination. Of the 149 patients 25 (17 per cent) were excluded from the study but 124 were evaluated for response and survival. Entry variables were distributed similarly among patients in each treatment arm. There were no complete or partial responders but there were nearly twice as many patients whose disease was stabilized (33 per cent) on the combination regimen compared to estramustine phosphate (18 per cent) and about a third more than for cis-platinum (21 per cent). Analysis of survival revealed some advantage for patients on combination therapy. Major toxicities for all treatments were nausea and vomiting (62 to 88 per cent) and accompanying anorexia (72 to 95 per cent). Azotemia developed in 45 per cent of the patients receiving combination therapy. In addition an elevation in serum creatinine occurred in 22 per cent of the patients receiving combination therapy and in 17 per cent of those receiving cis-platinum alone. Myelosuppression occurred infrequently.

In this clinical trial of men with advanced prostatic cancer no longer responsive to hormone therapy 189 were randomized to receive estramustine phosphate, methotrexate or cis-platinum. Response evaluations were done in 158 cases. Objective response rates (complete, partial or stabilization of disease) were 34 per cent for estramustine phosphate, 36 per cent for cis-platinum and 41 per cent for methotrexate. Subjective parameters indicated a substantial advantage for pain improvement with methotrexate or cis-platinum over estramustine phosphate. Probabilities of continued response indicated some advantage for methotrexate and median response durations at this time were twice as long for methotrexate (32 weeks) as for cis-platinum (16 weeks), with estramustine phosphate intermediate (23 weeks). Survival rates for the original treatment randomization groups were not different at this time. Side effects of estramustine phosphate consisted primarily of nausea and vomiting and/or anorexia but to a lesser extent than with cis-platinum. These effects were somewhat less for methotrexate, for which the major side effects were stomatitis and leukopenia, as well as hepatic toxicity reflected by elevated serum glutamic oxaloacetic transaminase levels. Other side effects of cis-platinum were less than for methotrexate (no stomatitis), except for signs of renal toxicity (elevations in blood urea nitrogen and serum creatinine), which were greater. Methotrexate had a relatively high level of activity against metastatic, progressive, hormone nonresponsive prostatic cancer, with side effects that were substantial but manageable.

Clinical study of UFT which was a mixture of FT and uracil, was conducted on 16 patients with urogenital malignancies. Seven patients had renal cell carcinoma, 5 patients had bladder cancer and 4 patients had prostatic cancer. UFT was continuously administrated at doses of 300 mg or 600 mg per day. One of the patients with renal cell carcinoma and 1 of the patients with bladder cancer showed a complete response, and 1 patient with each cancer showed a partial response, but none of the 4 patients with prostatic cancer responded. In total, complete or partial responses were obtained in 4 of the 16 patients, given an effective rate of 25.0%. Concerning side effects, 3 of the 16 patients complained of anorexia, nausea and vomiting, and stomatitis, but no hepatic or renal disorders, or marrow depression was observed.

Phase II study of cis-diaminedichloroplatinum(II) (CIS-DDP) administered intravenously was performed in 77 patients with urologic malignancies for the evaluation of clinical responses and adverse effects. The eligibility of the patients and evaluation of response were carried out according to the general criteria proposed by Drs. Koyama and Saito. Out of 85 patients, entered in this phase II study, 77 patients were considered evaluable. Complete responses were seen in 4 patients, 3 testicular tumor and 1 bladder cancer. Partial response were obtained in 24 patients; 10 bladder cancer, 8 testicular tumor, 5 prostatic cancer, and 1 renal cell carcinoma. Overall response rates were 73.3% in testicular tumor, 50.0% in bladder tumor, 20.8% in prostatic cancer, and 7.7% in renal cell carcinoma. Incidences of toxicities were noted in the gastrointestinal tract. Nausea, vomiting, anorexia, abdominal pain, and diarrhea were observed in 78.5% of the patients treated with CIS-DDP. Myelosuppression, lassitude, renal and hearing dysfunction were other prominent adverse effects.

Total prostatectomy in the properly selected patient will provide disease-free survival rates comparable to the expected survival in similarly aged men for up to 30 years of observation (Figure 4). Patients who undergo total prostatectomy accept a very small risk of long-term permanent complications or mortality, and effective treatment is available for most complications. The morbidity and costs associated with hormone refractory metastatic prostate cancer are significant, with bone pain and anemia from bone marrow invasion, bladder dysfunction (retention, incontinence, and hematuria), urinary tract infection, anorexia, and uremia from obstructed ureters being common sequelae in the months before death. In the properly selected patient, minimal risk is incurred from total prostatectomy, the potential complications are well defined and manageable, and long-term disease-free survival is seen in most patients.

A phase I study of orally administered flutamide (a pure anti-androgen) was performed in 26 patients with prostatic cancer. No side effects were observed in 11 patients receiving single doses of either 125, 250, 375 or 500 mg. However, in the daily dosing schedule of 375, 750, 1125 and 1,500 mg/day doses, where medication was taken in three divided doses, discomfort in the stomach, nausea, vomiting and anorexia were experienced in one of the four patients receiving the highest dose of 1,500 mg. Nine patients receiving the other doses did not complain of toxic symptoms. Laboratory values did not change in the three patients receiving the lowest 375 mg/day dose, but elevation of transaminase was observed in five of the nine patients given higher doses. This elevation was observed in all the three patients receiving 1,500 mg/day dose. Among the serum hormone levels, significant increases of luteinizing hormone were observed. As for efficacy, objective responses were observed in two of the three patients in each of the four daily dosing groups. Improvement of pain, voiding obstruction symptoms, and performance status were also observed. Flutamide was found to be absorbed rapidly and to exist as a hydroxylated form (hydroxy-flutamide) in the plasma. The half-life of hydroxy-flutamide was similar in the single and daily administration, but the peak concentration and area under the concentration versus time curve in the daily administration became greater than those in the single administration. In conclusion, flutamide should be examined for efficacy and safety using doses of 375 to 1,125 mg/day in the phase II study.

Despite the advances being made in prostate cancer screening and early detection, a large percentage of patients will eventually be classified as "hormone refractory." Patients entering this phase are no longer curable, and therapies instituted in this setting are primarily palliative in nature. As a result, the onus on those working in the field of urologic oncology becomes managing the plethora of symptoms these patients experience as a result of both their disease and the treatment modalities used at this stage. The intent of this article is to provide an overview of some of these symptoms with guidelines for their management. Principles of pain management and additional manifestations requiring supportive care such as anorexia, constipation, anemia, urinary obstruction, and psychological concerns are discussed.
