Results of disease-oriented phase II trials with cis-dichlorodiammineplatinum(II) (cis-platinum) in 135 adequately treated patients with advanced urothelial tumors at Memorial Sloan-Kettering Cancer Center are presented. In four protocols which used cis-platinum alone or in combination with Adriamycin and/or cyclophosphamide in 95 patients with bladder cancer, no significant difference (46%--54%) in the number of partial remissions (PRs) in previously untreated patients was noted. The median duration of response in three of the four protocols was 5--7 months. A review of the literature indicates that cis-platinum used singly produced remissions in 45% of 67 patients (95% confidence limit, 12%--57%). In the treatment of superficial bladder tumors, intravesically administered cis-platinum induced few complete or sustained remissions. The difficulties in evaluating response with intravesical therapy are discussed. The importance of patient selection, particularly the need to include patients with objectively measurable disease parameters, in phase II trials is stressed. Differences in patient characteristics and response criteria will necessitate prospective randomized trials of cis-platinum alone versus cis-platinum combination regimens in the treatment of metastatic disease. cis-Platinum was inactive (12% PRs) in 25 patients with prostatic cancer who had objectively measurable parameters. It is of interest that PRs were obtained in three of six patients (50%) with penile cancer. A review of the literature and the data in the present series indicates that cis-platinum has no value in the treatment of metastatic hypernephroma.

The diagnosis of prostatic cancer must be proved by biopsy. Transrectal fine needle biopsy and punch biopsy are also useful methods for the outpatient clinic. Besides X-ray examination scanning angiography and lymphography may be used to identify metastases. Combined antiandrogenic therapy is still the treatment of choice and is based on endocrinologic analysis of testosterone, LH levels and testosterone-binding beta-globulin. Radionuclids (32P, 89Sr) should be used for treating metastases of the bone. Chemotherapeutic substances showed unsatisfactory results. Radical prostatectomy can only be performed in 5 to 10% of all patients with prostatic cancer to metastases in T1 and T2 cases. Since 1965 the radiation therapy (linear accelerator or (60Co-source) gives more hope. We treat patients free from metastases with a 60Co-source (right and left lateral 120-degree arc rotational therapy with 5000 rads over 5 weeks) combined with hormonal therapy. The therapeutic effect is checked by fine needle aspiration biopsy.

An essential part of the classification of prostate carcinoma is the diagnosis of bone metastases. This was done with 70 patients using x-ray analysis, scintography, determination of the acid and alkaline phosphatase, and pelvic crest biopsy, as well as aspiration of the pelvic and sternal bone marrow. In addition, the hydroxyproline concentration was determined in the 24-hour-urine. The study, which was initially undertaken on a sample group (n = 145), yielded a high correlation between age and sex and hydroxyproline values. Women before menopause show significantly lower values than do men of the same age. The data on patients with prostata cancer (n = 70) showed that patients with and without bone metastases, who had been treated with estrogens, had a significantly lower quantity of hydroxyproline than did patients who had not received estrogen therapy. Patients with skeletal metastases (n = 24) showed significantly higher hydroxyproline excretion in the urine than did those with prostate cancer without metastases, or healthy men of the same age (n = 35). Comparison of the results of hydroxyproline determination with the other diagnostic methods for demonstrating bone metastases showed that hydroxyproline determination was diagnostically on par with the scintigram. Pelvic crest biopsy, pelvic and sternal marrow aspiration can be considered valuable supplementary diagnostic procedures.

Eighty-eight patients with hormone-resistant Stage IV prostate cancer were treated with a five-drug chemotherapy program. Patient demographic data, prior therapy, symptoms, extent of disease, and laboratory studies were analyzed statistically to evaluate the association of these parameters with survival from the onset of chemotherapy. Factors associated with short survival included age greater than 65, severe bone pain, poor performance status, presence of soft tissue metastases, anemia, elevation of serum LDH, SGOT, alkaline and acid phosphatases, and prolactin, and hypoalbuminemia. Race, stage at initial diagnosis, prior radiation therapy, prior orchiectomy, and elevation of CEA had no prognostic association. We suggest that clinical trials of new therapies of hormone-resistant prostate cancer take into account the presence of these prognostic factors in the analysis of the results of therapeutic programs.

Plasma concentrations of testosterone, oestradiol-17 beta, luteinising hormone (LH), follicle stimulating hormone (FSH), prolactin and growth hormone (GH) were measured in patients with histologically proven prostatic cancer, before any form of therapy was given for this disease. Patients were categorised according to UICC classification. No systemic change in the group means of any of these hormones was associated with the progression of the disease from the T0 to the T4 stage. When multivariate analysis was applied to the combined intraprostatic (T0 + T1 + T2) and extraprostatic (T3 + T4) tumour category in patients without clinically evident metastases (M0) a discrimination was observed, GH substantially contributing to the separation of the 2 groups. When plasma hormone data from patients classified as M0 (without metastases) were compared with M1 patients (with metastases), mean GH values were significantly larger (P less than 0.02) in patients with metastases. GH was also a major contributory factor to the discrimination between the M0 and M1 groups, using multivariate analysis. Testosterone group means for M0 versus M1 were also significantly different (P less than 0.02).

We report three patients evaluated on a medical service for lymphoma-like signs and symptoms. Although none had prostate or bone symptomatology, all three were found to have metastatic prostate cancer. These cases emphasize the propensity of prostate cancer to metastasize to lymph nodes as well as bones. Diagnostic and therapeutic implications are discussed.

130 serial bone scintigrams were performed to evaluate the course of skeletal metastases under treatment in 36 patients with prostatic cancer. During a successful treatment scintigraphic controls revealed a significant decrease of the metastatic 99mTc-diphosphonate uptake in 14 patients and sometimes even a complete normalization of the skeletal radioactivity distribution, whereas a progression characterized by an increased multifocal radioactivity concentration was registered in 16 patients indicating the failure of the initiated therapy. Based on these results of follow-up studies scintigraphic bone imaging can be recommended for the assessment of the effectiveness of on-going therapy of skeletal metastases.

A prospective study was done to evaluate 47 patients with early stage prostatic cancer. Pelvic lymphadenectomy was combined with bone marrow acid phosphatase determination to evaluate early metastatic disease. Thirteen patients (28 per cent) had tumor in the pelvic lymph nodes. In no instance was the bone marrow acid phosphatase elevated to more than the normal value for serum by the substrate used. Combined high grade and stage tumors seemed to have an increased incidence of metastases to pelvic lymph nodes. A surprisingly high incidence of B1 lesions (5 of 21 patients or 24 per cent) had positive lymph nodes. Generally, the nodes were moderately well or well differentiated lesions. The metastases were unilateral, frequently microscopic only and involved 1 or only a few nodes. Pelvic lymphadenectomy seems to have a well defined role in the diagnostic study of early stage prostatic cancer, while bone marrow acid phosphatase determinations were of no value.

Bone marrow acid phosphatase has been reported to be a sensitive indicator of early bony metastasis from adenocarcinoma of the prostate. In order to evaluate this hypothesis, we measured bone marrow acid and alkaline phosphatase, lactic dehydrogenase, and calcium levels in a group of 84 patients with a variety of problems, including 18 with cancer of the prostate. We found that the bone marrow acid and alkaline phosphatase and lactic dehydrogenase were elevated and calcium was depressed in most patients. Among patients with prostate cancer, bone marrow acid phosphatase was not significantly different between those with or without bone metastases. In addition, the patients with prostatic cancer did not have higher levels of bone marrow acid phosphatase than subjects with other malignant and nonmalignant conditions. The level of acid and alkaline phosphatase, lactic dehydrogenase and calcium varied predictably with the aspiration technique used and was independent of sex, disease state or method of chemical determination. Due to this variation, we believe that bone marrow enzyme and calcium levels are of no value in the detection of metastases in patients with prostate cancer.
