The potential value of indium-labelled bleomycin as a diagnostic scanning agent has been investigated in patients with a variety of malignant neoplasms involving the thorax, abdomen or pelvis. Sixty-five patients were scanned on 72 occasions, the optimum time to perform the examination being 72 hours after the intravenous injection of 2 mCi 111-In chelated to 2 mg bleomycin. Tumour uptake was visualized in 53 out of 62 scans in which tumour was present, but the extent of tumour was underestimated in seven cases, and over-estimated in five others. The latter were mostly due to uptake in infective lesions. These results indicate that the situations in which indium bleomycin is most likely to provide clinically relevant information are the distinction between recurrent tumour and post-radiotherapy changes in the thorax and pelvis, the diagnosis of recurrent carcinoma within the pelvis, and the distinction between bony metastases from carcinoma of the prostate and Paget's disease. Further clinical trials are necessary to assess these situations.

Thirty-three patients with intractable pain caused by diffuse osteoblastic metastases from carcinoma of the prostate were treated with phosphorus-32 (32P) therapy either androgen priming, parathormone rebound, or a combination of both priming methods. Significant response to pain was achieved in 12 of 19 patients receiving testosterone-potentiated therapy, 0 of 5 patients treated with parathormone alone, and 6 of 9 patients receiving a combination of both priming modalities. It is concluded that androgen priming alone is the simplest and most effective method to be used when 32P therapy is being considered for palliative control of pain in patients with carcinoma of prostate.

The binding of 3H-R 1881 to cytosol prepared from benign and malignant prostatic neoplasms has been investigated. We have demonstrated that high affinity binding of 3H-R 1881 is present in cytosol preparations of benign prostatic hyperplasia, in specimens of prostatic cancer obtained from patients prior to hormonal therapy and in carcinoma of the prostate metastatic to lymph nodes. In addition, high affinity binding was present in all specimens of prostatic cancer from patients who had objective evidence of progressive metastatic disease after an initial response to hormonal therapy. Until greater numbers of patients have been studied the significance of these findings can only be speculative. Because the binding of 3H-R 1881 may measure androgen and progesterone receptors future investigations must include careful steroid specificity studies. Finally, because steroidal hormones exert their major influence within the nucleus of target tissues the measurement of nuclear receptor content may provide a more accurate means to predict the hormonal responsiveness of prostatic cancer.

Sera from patients with carcinoma of the prostate were screened for the presence of blocking factors by measuring the inhibition of phytohemagglutinin-induced blastogenesis of normal lymphocytes. The blastogenic index obtained in cancer sera is not significantly different from that obtained in sera of patients with benign prostatic hypertrophy (control group). Determination of alpha-2-globulins in the cancer sera by cellulose acetate electrophoresis revealed slightly elevated levels in patients with metastatic disease but it did not correlate with the inhibitory blocking activity of the serum.

A series of 59 consecutive patients with inoperable carcinoma of the prostate were entered into a national cooperative study and treated under the tenets of a strict protocol with competent dosimetric control. Twenty-one of these men are living and well 5--10 years after treatment; nine others who lived without cancer from 5 to 10 years died of other diseases. Local recurrences were not demonstrated in several cases which came to autopsy. Failures are often due to the development of osseous metastases outside of the effective area of radiotherapy. Untoward effects are the exception and may be minimized by fractionation.

The validity of individual radiological signs for the differentiation of osteoplastic bone metastases from osteitis deformans has been investigated quantitatively (103 skeletal metastases from carcinoma of the prostate, 45 cases of Paget's disease, two osteoplastic bone metastases from a carcinoma of rectum and bronchus). The similarities were demonstrated by three cases observed by us. Problems in the quantitative evaluation of the radiographs are discussed.

Locally recurrent, poorly differentiated carcinoma of the prostate was associated with hypokalemic alkalosis, marked hypernatremia, diabetes mellitus of recent onset, and hyperosmolar syndrome. These findings, with mild hypertension, in the absence of clinical features of Cushing's syndrome, suggested an ectopic ACTH syndrome. Plasma ACTH and cortisol levels were markedly elevated, and failed to suppress in response to either low or high-dose dexamethazone administration. The patient's condition deteriorated rapidly. Autopsy findings included carcinoma extensively infiltrating the prostate with extension to the urinary bladder, and metastases confined to the pelvic nodes and soft tissues. The adrenal glands weighed 23 g and showed diffuse hyperplasia. Extract of the prostatic tumor was analyzed for ACTH and showed approximately 40 times normal plasma levels (or about 4,010 pg/g of tissue); ultrastructural features showed secretory granules consistent with ACTH content of the tumor cells. Such cells were positive when stained for ACTH by peroxidase-tagged immunochemical methods. The case fulfills all established criteria for relating excess corticosteroid production and nonpituitary tumors.

3 cases of inappropriate vasopressin secretion during one case of anaplastic carcinoma of the lung, one case of carcinoma of the prostate with bony metastases and one case of acute intermittent porphyria are presented. The plasma levels of vasopressin, measured by radioimmunoassay were high. Treatment with demeclocycline was attempted in one case. The clearance of free water was positive but the treatment was poorly tolerated by the digestive tract.

The fourth report of our long-term study concerns 70 cases of primary radiotherapy. The side effects of our radiation technique are minimal and temporary; in over 80% of the cases, potency was not affected. The morphologically demonstrable changes in the tumor tissue, in the original glandular parenchyma, and in the fibromuscular stroma leading to the vessels following high-voltage therapy are described. Three types of progressive patterns, based on the grade of histologic regression, can be determined. In more than half of the cases, with increasing distance from the source of radiation, no tumor or only minimal residual tumor was demonstrable. Sensibility and resistance of carcinoma of the prostate are not dependent upon the grade of differentiation of the tumor. A prognostic statement concerning the success of radiation therapy from initial histologic findings is not possible here. The occurrence of metastases in 18% of the cases following radiation probably resulted from the inexactness of the purely clinical determination of the stage of the tumor. The isolated, local treatment of prostate carcinoma through radiotherapy is justified only after exact determination of the stage of the tumor, i.e., certain exclusion of metastases via a diagnostic lymphadenectomy.

In a prospective autopsy study of male subjects with solic malignant neoplasms, six were shown to have metastatic deposits within the testis (2.5%). These were metastases from carcinoma of the prostate (two cases), melanoma (two cases), bronchial carcinoma (one case) and pleural mesothelioma (one case). In addition, four of 29 leukaemic patients and six of 28 with non-Hodgkin's lymphoma showed testicular involvement. The metastases from the solid tumours presented in solitary nodules, as multiple nodules or as a diffuse involvement. Microscopically, these were represented by tumour cells within the interstitial tissue without involvement of the seminiferous tubules; interstitial tissue and tubular involvement, and tumour confined to the seminiferous tubules respectively.
