We have treated 77 patients for clinically early stage carcinoma of the prostate, 9 stage A2, 63 stage B and 5 stage C, with direct implantation of 125I seeds into the prostate and pelvic lymphadenectomy. It is estimated that a minimum dose of 15,000 rad but a maximum dose of 35,000 rad is delivered to the prostate over several months. Of the 77 patients 14 (18 per cent) had metastatic disease in the pelvic lymph nodes. In 22 cases perineal needle biopsy was done 12 to 18 months after treatment and in 3 cases a second biopsy was performed after 2 to 3 years. Persistent tumor was present in 11 biopsies. Cytological changes were observed in 8 of these, primarily cytoplasmic vacuolation and nuclear pyknosis. There seemed to be no relationship between grade and stage of disease and histological evidence of persistence of tumor after radiation. One patient with persistent tumor in the postoperative biopsy has shown progression of disease after 2 years and another with a negative biopsy has a bony metastasis. The remaining 10 patients with persistent tumor have shown no sign of progression of disease during a 2 to 4-year interval.

Our examinations allow the following conclusions: 1. Before the beginning of a curative radiotherapy of the carcinoma of the prostate gland in a negative and questionably positive lymphogramme the pelvic lymphadenectomy with histologic examination of the lymph nodes is indicated. 2. In the negative findings of the histologically examined lymph nodes an exclusive local tumour irradiation is justified. 3. If in regional and negative findings micrometastases appear in the area of juxtaregional lymph nodes the additional curative irradiation of the pelvic lymph nodes seems to be indicated for the comprehension of the regional lymph nodes. 4. When there are micrometastases in the area of the aa. iliacae communes or macroscopically extended metastases in the regional and juxtaregional lymph area, so we regard as a rule a radiotherapy of the carcinoma of the prostate gland no more indicated and recommend a contrasexual treatment. The necessary expansion of the radiotherapy is according to our hitherto existing experiences badly tolerated by the for the most part older patients. 5. The intraoperative labelling of the prostate gland and the determination of the size of the prostate gland facilitate the localisation of the tumour for the radiotherapist.

Alterations of serum creatine kinase isoenzymes were observed in five cases of prostatic carcinoma. Creatine kinase isoenzyme BB was found in the serum of two of three cases with metastases. Its presence in serum does not seem to be related to acid phosphatase activity but seems associated with extension of the tumor to other tissues. Preliminary studies on effusions from patients with malignant and non-malignant prostates showed that CK-BB was detectable only in cytology positive effusions. This finding suggests that CK-BB may be a tumor product rather than a result of a host response. The observation of CK-BB in a significant percentage of patients (two of three) with metastatic carcinoma of the prostate is of interest and suggests that CK-BB isoenzymes may have some predictive value in following patients with malignant disease.

Two cases of epididymotesticular metastases are reported: one epididymal from a carcinoma of the kidney by retrograde venous spread and the other testicular secondary to a carcinoma of the prostate and apparently by arterial spread. Epididymotesticular metastases of carcinomas are rare. When the initial carcinoma is known, or even treated, the development of a large testis should lead to consideration of the possibility. Treatment should consist of inguinal orchidectomy with ligation of the spermatic cord as high as possible.

A progress report on the treatment of 116 patients with adenocarcinoma of the prostate treated by external irradiation is presented. Fifteen, 60, and 41 patients presented initially with Stages A, B, and C, respectively. The majority of the patients received 7,000-7,500 rads during a period of seven to eight weeks, locally to the prostate gland. The five-year actuarial survival were 90, 70, and 40 per cent for Stages A, B, and C, respectively. The five-year survival rates for patients with well and moderately differentiated tumors were significantly better (45 per cent) than for those with poorly differentiated tumors (24 per cent). The five-year survival rate in the patients who received prior or concomitant hormone manipulation was lower (33 per cent) as compared with those receiving radiation therapy alone (43 per cent). All of the above differences were statistically significant (0.01 level). Of the patients failing, distant metastases have developed in 88 per cent suggesting that subclinical distant metastases might have been present prior to initiation of radiotherapy. The local control rate was 82 per cent. The morbidity of this mode of therapy was found to be acceptable. Radical radiation therapy is an effective method for control of carcinoma of the prostate and is potentially curative.

Urinary hydroxyproline (HP) excretion has been estimated without prior dietary restriction in 33 patients with carcinoma of the prostate and expressed as either 24-h HP output or as the hydroxyproline/creatinine (HP/Cr) ratio in 24-h urine sample, an early morning urine sample or a spot urine sample. The early morning urine hydroxyproline/creatinine ratio (EMU HP/Cr) appears to be the most accurate and avoids the disadvantages of formal dietary restriction and prolonged urine collection. The rest is useful in monitoring the responses to treatment of a patient with bony metastatic disease and relapse of a patient when his tumour ceases to be hormone sensitive. Furthermore, changes in EMU HP/Cr occur earlier than changes in other clinical or investigative variables, giving the test predictive value.

Seventy-four patients with carcinoma of the prostate were studied annually by combined radiological and 18F scintigraphy over a 5-year period. Of the patients who have no radiological evidence of bone metastases, 25% have a positive 18F bone scan. Follow-up of these patients has shown that scan abnormalities perceded x-ray changes from between 1 to 4 years. False negative scans were not seen with 18F which allows for greater accuracy in the detection of skeletal metastases. Teh accurate staging of carcinoma of the prostate cannot be made without bone scanning. Preliminary results with 111In bleomycin as an adjunct to 18F have shown this to be a useful radio-pharmaceutical to distinguish metastases from benign lesions, and further studies are warranted.

Forty-one patients with metastatic carcinoma of the prostate (stage IV) were treated with diethylstilbestrol or bilateral orchidectomy or both and followed for a period of two years. The effect of treatment was determined every six months and was based on the size and consistency of the primary lesions on rectal palpation, the effects on pain, obstructive symptoms, osseous metastases, level of serum prostatic acid phosphatase and on the overall clinical evaluation of the patient. Bilateral orchidectomy was as effective as a combination of bilateral orchidectomy and diethylstilbestrol therapy. Diethylstilbestrol given alone was less effective. The poorer results obtained were attributed to the failure of many patients to adhere strictly to their estrogen regimen. Rectal digital palpation of the prostate as well as an estimation of the level of serum prostatic acid phosphatase is recommended in developing countries for all male patients over 50 years of age seen at the hospital.

24-hour urinary hydroxyproline excretion (THP), a marker of bone collagen metabolism, has been measured in 35 patients with carcinoma of the prostate. 21 patients had bone metastases diagnosed by bone scanning (99mTc MDP). All 9 patients with metastases studied before hormonal treatment and the majority of those on treatment had elevated levels. Patients with negative bone scans invariably had normal THP levels. Furthermore, THP reflected the presence of bone metastases more accurately than plasma alkaline or acid phosphatase. Serial THP levels altered predictably with symptomatic response to treatment. These results suggest that THP is more reliable than other markers of the presence and activity of bone metastases in response to treatment and may have been neglected in favour of more elaborate and costly X-ray and isotope investigations.

Radiographic evaluation of 65 patients with disseminated carcinoma of the prostate shows that 8% demonstrated resolution of metastatic deposits after palliative transurethral resection and/or estrogen or castration therapy. The increased effectiveness of therapy and the improved management of patients are reflected in longer survival. Roentgenographic evidence of increasing sclerosis of osteoblastic metastases of carcinoma of the prostate indicates that the rate of bone repair exceeds the rate of bone destruction, and is not necessarily an indication of progression of the disease. Increasing prominence of blastic bony lesions is not a poor prognostic sign; several patients showing it were symptom-free and survived for long periods. Sclerotization of lytic deposits is definitely a good prognostic sign of treatment and represents "healing change" within involved bone.
