We reviewed 166 cases of renal cell carcinoma. The presenting symptoms varied from vague backache to hypovolemic shock. The most common symptoms were pain, hematuria, a palpable mass and hypertension. Most cases involved were clear cell carcinoma (83 per cent) and survival was no better than in cases of granular cell carcinoma. The tumors metastasized to almost every organ of the body. Bilateral simultaneous primary renal cell carcinoma is described in 1 patient, who has survived for more than 5 years. The over-all 5-year survival rates of simple and radical nephrectomy were 32 and 66.6 per cent, respectively. Radiation therapy does not improve survival irrespective of stage. The 5-year survival rate with renal vein involvement was 32 per cent. Nephrectomy in patients with distant metastasis did not alter survival. Among the patients with metastasis 74 per cent were dead before 1 year and 96 per cent before 3 years.

Sixteen patients with prostatic carcinoma were treated with 200 mg of Cyproterone acetate daily. No other kind of hormonal treatment was administered. Increasing skeletal metastases were observed in 6 patients, whereas significant reduction of metastases took place in 2 patients. Objective relief of stranguria was observed only in 3 patients. The amount of residual urine increased in 3 patients and was reduced in 5. In about one third of the patients, the prostate gland became smaller and softer. The acidic phosphatases decreased from pathological to normal values in 7 patients. There were no observed hepatic, renal or haemotological side-effects. However, serious cardio-vascular complications occurred in 6 patients, while arterial hypertension developed in 4. It is suggested that Cyproterone acetate cannot be recommended as the only kind of hormonal treatment of prostatic cancer.

The results of studies conducted on 355 white nonpedigree male rats (268 experimental and 87 intact animals) indicated that nephrogenic hypertension: a) potentiates the development of benz(a) pyrene induced blastomas; b) enhances, as a rule, the growth of transplantable tumors: carcinoma RS-1 and sarcoma 45; c) results in a tendency to more frequent metastasization of the tumors (Walker carcinosarcoma and Zajdela ascites hepatoma).

Malignant disease of the female reproductive organs accounts for over 11,000 deaths annually in the United States in patients over 65 years of age. Hormonal treatment is being used in some cases in conjunction with more conventional methods of treatment. Synthetic progesterone is used in the palliation of patients with advanced adenocarcinoma of the endometrium. A significant increase in the incidence of ovarian cortical stromal hyperplasia, obesity, diabetes and hypertension is found in these patients. For treatment of carcinoma of the ovary, a massive dose of an experimental progesterone agent, dimethylprogesterone (NSC-123018) is being tested in a group study. The treatment is used only for patients for whom conventional therapy has been unsuccessful. Although a few patients have shown remission, it is too early for conclusive results. Patients with advanced breast cancer and estradiol receptors in their tissue may show a favorable clinical response to hormonal therapy in 40-60% of cases. Patients lacking estrogen receptors have only a minimal chance of responding to hormonal therapy.

The case of a young boy who had Cushing's syndrome and severe hypertension in association with metastatic adrenal carcinoma is described. Marked elevation of the mineralocorticoid 11-deoxycorticosterone was demonstrated in the plasma. 11-Deoxycortisol, 17alpha-hydroxyprogesterone, and urinary tetrahydro-11-deoxycortisol and pregnanetriol were also elevated. Aldosterone excretion was low. The data implicate defective 11beta hydroxylation and suggest that excessive 11-deoxycorticosterone production may have been responsible for the hypertension.

The primary symptoms and signs, indicating urography, in 369 patients with renal carcinoma have been reviewed. Gross haematuria was noted in 33%, signs of malignancy in 20% and in 13% metastases were first diagnosed. In 15% the renal tumor was an incidental finding at urography performed because of prostatism, cystopyelitis, hypertension and prostatic carcinoma. It is concluded that every urography must have such a high quality as to be able to evaluate the entire urinary system in all patients, as a renal carcinoma may be found at urography in any patient above the age of 30 years.

Twenty-two patients were given progressively increasing doses of Cytembena to determine toxicity patterns and to establish a dosage which produces definite but clinically tolerable toxicity when the drug is given by intravenous injections in a 5-day intensive course. Toxicity consisted primarily of nausea, vomiting, arm pain, and transiently decreased renal function. At higher doses, an "autonomic-storm" phenomenon was observed consisting of hypertension, tachycardia, tachypnea, hyperperistalsis, frequent explosive defecation, facial flushing and paresthesias, and chest pain with accompanying ischemic EKG changes. There was no evidence of mucocutaneous, hepatic, or hematologic toxic effects. Toxicity was dose-related, first being recognized at a daily dose of 300 mg/m2 and becoming clinically intolerable at a daily dose of 475 mg/m2. No permanent damage was observed in any of the organ systems monitored. An acceptable treatment regimen for most patients is 400 mg/m2/day for 5 days. Patient discomfort can be reduced by dividing each day's dose into two intravenous injections given at an interval of at least 6 hours. Coronary artery disease and impaired renal function should be contraindications to Cytembena therapy, and caution should be employed in the patients with significant impairment of liver function. Two of 22 patients, both with far-advanced carcinoma and previous chemotherapy failures, showed a favorable objective response to Cytembena therapy. Phase II studies to assess the magnitude of the drug's antineoplastic activity seem warranted.

In a retrospective study characteristics of 729 climacteric and postmenopausal women with hyperplasia and adenocarcinoma of the endometrium are compared with those of 82 women with atrophic endometrium and 96 women with carcinoma of the cervix. In a prospective study 225 women with glandular-cystic, adenomatous and atypical hyperplasia of the endometrium have been checked by a control-curettage within a period of two months until four years following the first diagnosis. Low parity, disturbances of menstruation with anovulatoric bleedings during fertility period, adipositas, hypertension and diabetes mellitus in climacteric and postmenopausal women indicate a high risk of carcinoma of the endometrium. Hyperplasias of the endometrium in climacteric women cannot be considered as precursors of corpus carcinoma. They are the result of a temporary hormonal dysfunction. Prophylactic hysterectomy, however, should be performed, if adenomatous or atypical hyperplasia appears in older postmenopausal women with the indicators of high risk of endometriumcarcinoma as mentioned above.

Two cases of delayed radiation necrosis of the brain were reported. Case 1 was a 50-year-old man who had right hemiparesis and disorientation 26 months after Linac irradiation (5,000 rad), preceded by the operation for right maxillar carcinoma. A left carotid angiogram demonstrated a left temporal mass lesion, extending the frontal lobe. Case 2 was a 41-year-old man who had previously the operation for right intraorbital plasmocytoma, followed by two times Co irradiation (6,400 rad, and 5,000 rad). He had the signs and symptoms of intracranial hypertension 36 months after last irradiation. A left carotid angiogram demonstrated a left temporal mass lesion. Both cases were treated by administration of steroid hormone, which alleviated the signs and symptoms, followed by the temporal lobectomy. Microscopic examinations showed necrosis of the brain tissues associated with hyaline degeneration of blood vessel walls and perivascular cell infiltration. The signs and symptoms of intracranial hypertension subsided postoperatively. The other thirteen cases as same as ours were collected from literature, which showed the signs and symptoms simulating a brain tumor (like a metastic brain tumor) after the irradiation to extracranial malignant tumors, and the diagnosis of radiation necrosis were made by the operation or autopsy. A follow-up for a long time is necessary, because the pathological changes in the brain may be progressive and extending in some cases, although the decompressive operations for mass lesion are excellent in result.

In an attempt to confirm three reports suggesting a causal link between rauwolfia antihypertensive drugs and female breast carcinoma, all cases of such cancer appearing among the residents of an affluent retirement community were compared with controls chosen from a roster of all women in the same community. Most residents use a single care facility, and patterns of hypertension diagnosis, rauwolfia and other drug use, and medical-care-system patronage were abstracted from medical records. The prevalence of recorded rauwolfia use among the controls were 20 per cent, and that of other drug use was correspondingly high. The risk ratio for rauwolfia use was estimated to be 1.2 (95 per cent confidence interval, 0.7 to 2.2). Risk ratios between 1.0 and 2.0 were also found for other drug use and for measures of care-system patronage. These results do not support the hypothesis that reserpine causes breast cancer.
