Abstract
One hundred and eighty-six previously untreated patients with clinical stage D2 prostate cancer have been followed according to the criteria of objective response of the National Prostatic Cancer Project (NPCP). All patients received combination therapy with the antiandrogen Flutamide and the LHRH agonist (D-Trp6, des-Gly-NH2(10)]LHRH ethylamide (or surgical castration, 10 patients) as first treatment. Forty-nine patients (26.3%) achieved a complete response as best response while 56 (30.1%) and 69 (37.1%) patients had partial and stable responses, respectively, and only 12 patients (6.5%) did not respond to treatment. The median times required to achieve stable, partial and complete responses were 155, 183 and 401 days, respectively. The best response achieved has a major influence on the probability of continuing response and survival. While the 50% probability of continuing response is more than 3 years for the complete responders, it is reduced to 630 and 517 days for partial and stable responders, respectively. While the non-responders have a median life expectancy of 10.0 months, this value is increased to 30.3 and 37.8 months for the stable and partial responders, respectively. The best probability of survival is for the complete responders with a 95.9% probability of survival at 3 years. There is no significant correlation between the time required to achieve a best response (phase 1) and the duration of the response before progression occurs (phase 2) or the time between progression and death (phase 3) for any of the categories of responses. A longer period of time required to achieve a complete response is associated with a longer survival. When analysis is made, in an attempt to predict response, of the baseline characteristics of the patients before treatment, a low number of bone metastases and better performance status are associated with a greater chance of achieving a complete response while partial, stable and progression responses cannot be predicted from the baseline characteristics. The present data show the importance of standardization of the objective criteria of response to treatment in advanced prostate cancer. Thus, the patients who achieve a complete response have a much more favorable prognosis while partial and stable categories of response have a closely similar prognosis which is inferior to the complete responders. Moreover, the present data indicate that the stable category of response has an important prognostic value which is almost superimposable and not statistically different from the partial response in terms of duration of response and survival.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
A total of 71 patients with prostatic carcinoma underwent radical prostatectomy combined with instillation of radioactive gold seeds between January 1, 1977 and July 1, 1982. Gold seeds were implanted intraoperatively into the region of the prostatic vascular pedicles and surrounding fibrolymphatic tissue after removal of the prostate and seminal vesicles. Of the patients with disease confined to the prostate clinically 46.7 per cent had microscopic extraprostatic local tumor extension. We believe that patients with extraprostatic local tumor derive therapeutic benefit from the addition of adjuvant radioactive gold seeds at prostatectomy. Because of the inaccuracy of clinical staging by rectal examination, we have elected to use radioactive gold seeds in all of our patients at prostatectomy. To date, local recurrence has been noted in 5.6 per cent of our patients and systemic progression in 14.1 per cent.

Abstract
Stable response to therapy in patients with advanced prostate cancer, as experienced in clinical trials of the National Prostatic Cancer Project (NPCP) has been re-examined. Data from 10 completed trials, totaling over 1300 patients, have been examined for survival patterns within categories of response to therapy. Survival patterns, for patients alive at 12 weeks, were significantly poorer for patients who were categorized as progressors after 12 weeks on treatment than for those who were categorized as stable or as partial regressions. Furthermore, comparisons of survival patterns for those patients who were categorized as stable or partial regression revealed no statistically significant differences between them. The concerns over the use of stable as an indicator of response and the problems in establishing its true meaning are discussed. All things considered, the use of stable is a valid means to evaluate the status of patients in clinical trials of treatment modalities for advanced cancer of the prostate.

Abstract
Stable response to therapy in patients with advanced prostate cancer, as experienced in clinical trials of the National Prostatic Cancer Project (NPCP), has been reexamined. Data from ten complete trials totaling over 1,300 patients have been examined for survival patterns within categories of response to therapy. Survival patterns, both for all patients and for those alive at 12 weeks, were significantly poorer for patients categorized as progressors after 12 weeks on treatment than for those categorized as stable or as partial regressions. Furthermore, comparisons of survival patterns for those patients categorized as stable or partial regression revealed no statistically significant differences between them. The similarity of survival for the stable and partial regression categories indicates that the stable category represents more than a segment of the population with slowly progressing disease and can be taken as an indicator of response to therapy.

Abstract
Cases of locally advanced prostatic adenocarcinoma (stages B and C) managed by exenteration or prostatocystectomy were reviewed. Local control and survival rates seem to justify this approach in selected cases, especially when conservative measures, such as hormonal therapy and irradiation, have been exhausted.

Abstract
Surgical therapy for early adenocarcinoma of the prostate has been an effective mode of cure since it was described by Young in 1905. The retropubic and perineal approaches of radical prostatectomy have been used at our hospitals for 25 years. Herein we examine 329 cases at the 2 hospitals. Although there were only 2 deaths (0.61 per cent) immediately attributable to the operation the surgical morbidity was significant. Patients of the attending staff had a 46 per cent complication rate while that of patients of the resident staff was 59 per cent. The 5 and 10-year survival rates of patients with stages A and B prostatic adenocarcinoma were 82 and 63 per cent, respectively, and the 5 and 10-year survival rates of patients who had stage C prostatic adenocarcinoma were 67 and 29 per cent, respectively. Our survival rates compare favorably to the national average survival for patients of all ages with localized or regional adenocarcinoma of the prostate. We believe that these data support the position of urologists who believe in radical surgical treatment of prostatic cancer.

Abstract
A total of 125 patients with progressing advanced prostatic cancer were entered into a chemotherapy study comparing cyclophosphamide, 5-fluorouracil, and standard therapy. Parameters of response were studied in 110 patients who could be evaluated. Thirty-six patients (33 per cent) were considered to have an objective response, that is becoming stable (29 patients) or in partial regression (7 patients). Negative response parameters (predictors of a poor response to chemotherapy or standard theraphy leading to progress) included (1) bone marrow evidence of prostatic cancer, (2) abnormal liver scan, (3) prior radiation therapy (indirectly through increased toxicity to chemotherapy), and (4) lack of bilateral orchiectomy prior to randomization. Positive indicators (predictors of good responses) included (1) reduction of primary tumor mass, especially after administration of 5-fluorouracil or cyclophosphamide, and (2) hemoglobin values. There were more objective responders to cyclophosphamide than standard therapy whether the hemoglobin was initially normal or low. Indeterminate parameters of response included weight gain, presence of bony or soft tissue metastases, relief of pain, performance status, excretory urography, and biochemical determinations of liver and renal function.

Abstract
Urinary excretion of the basic polyamine, spermidine, was significantly elevated in patients with prostatic carcinoma as compared to a control group of patients, Of 44 urine specimens from patients with prostatic malignancy 31 had spermidine levels more than 2 mg. per 24 hours, while only 3 of 13 urine specimens from the control groups had levels in excess of this value. The increase in spermidine appeared to be correlated with the histologic grading of the tumor, that is 30 of 34 specimens from patients with grade II, III or IV carcinoma had excessive spermidine excretion and only 1 of 10 urine specimens from patients with grade I tumors had similiar spermidine elevations. High spermidine levles were found in tumors localized to the prostate and in 7 of 8 patients with negative pelvic and para-aortic lymph node biopsies. This study raises the possibility that urinary spermidine determinations may aid in the development of a biochemical screening test for prostatic neoplasms.

Abstract
A review was done on 88 cases of carcinoma of the prostate treated with supervoltage radiotherapy and evaluated at regular intervals with post-treatment needle biopsies. A disturbing 58 per cent (45 of 77 cases) had histologic evidence of residual carcinoma at 1 year post-radiation. In 47 per cent (21 of 45 cases) of patients receiving 7,000 to 7,500R the biopsies were positive. No undue morbidity was experienced with radiation levels at 7,000R. Prostatic needle biopsy is considered mandatory for adequate clinical evaluation post-radiation. Since 41 per cent of patients judged radioresponsive on rectal palpation had positive biopsies at 12 months the data indicate considerable error in the clinical assessment of the irradiated prostate when reliance is placed solely on digital evaluation.
