A 65-year-old woman with a history of a left heminephrectomy for renal carcinoma developed hypercalcaemia 11 years after the operation. The same kidney was found to contain a recurrent renal carcinoma. After the radical nephrectomy of the left kidney, hypercalcaemia remitted but reappeared 11 months later. The right kidney was small but functioned at a level of creatinine clearance of 10--15 ml/min. Metastatic work-up was negative, and secondary causes of hypercalcaemia were excluded. A neck exploration revealed a parathyroid adenoma. With parathyroid resection the serum calcium declined to normal, and the risk of hypercalcaemic nephropathy in the remaining kidney was precluded.

The observation of a non-metastatic reactive hepatopathy associated with a hypernephroma in a 39-year-old man who had had fever for 4 months led to a review of the literature and an analysis of basically three aspects of the disorder: a) The various manifestations of carcinoma of the kidney, which include a large number of paraneoplastic clinical symptoms (polycythemia, anemia, prolonged fever, hypercalcemia, hypertension, nefropathy, loss of salt, peripheral neuropathy, and amyloidosis); b) an alteracion of hepatic function known since 1961 which is characterized by an abnormal retention of sulfobromophthalein, increase of alkaline phosphatase, prothrombin decrease, dysproteinemia with hypoalbuminemia, and alpha2-globulin increase. It may or may not be accompanied by enlargement of the liver. c) Criteria of operability of the primary tumor.

A case of renal carcinoma with hepatic dysfunction and hypercalcemia is described. The literature on Stauffer's syndrome has been reviewed and the pathogenesis of this syndrome discussed. It is stressed that the presence of hepatic dysfunction should not be considered a contraindication to surgery since its manifestations have been observed to regress in many cases following removal of the tumor.

The first case of primary hyperparathyroidism associated with renal cell carcinoma, nasopharynx carcinoma and thyroid carcinoma is reported. Selective venous sampling with radioimmunoassays for parathyroid hormone was helpful in the differentiation of primary hyperparathyroidism from hypercalcemia associated with malignancy.

Renal cell adenocarcinoma can be one of the great masqueraders in medicine. More common extrarenal manifestations of renal cell carcinoma include fever, anemia and gastrointestinal symptoms. Other rarer systemic symptoms are caused by amyloidosis, neuromyopathy and tumor thrombus. Humoral manifestations include polycythemia, hypercalcemia, galactorrhea and Cushing's syndrome. Metastatic disease commonly presents as the initial symptom.

The syndrome of hypercalcemia in patients with renal cell carcinoma without metastasis to bone, in association with elevated levels of immunoreactive prostaglandin E and normal parathyroid hormone levels, prompted the investigation of an etiologic relationship of increased prostaglandin in this syndrome. Ethyl acetate extracts of tissue culture effluents, primary and metastatic renal cell carcinoma, and plasma were chromatographed on silicic acid columns and assayed by double antibody immunoprecipitative methods for immunoprecipitative methods for immunoreactive prostaglandins A and E. Increased levels of immunoreactive prostaglandins A and E were found 1) to be generated in parallel with cell growth during a period of time by renal cell carcinoma in monolayer growth, 2) in extracts of primary and metastatic renal cell carcinoma tissue and 3) in the venous effluent of a kidney bearing a renal cell carcinoma. These findings support the hypothesis that renal cell carcinoma can produce prostaglandins. Furthermore, reported syndromes of patients with renal cell carcinoma associated with elevated prostaglandin levels may result from the autonomous production of prostaglandins in vivo by the tumor.

A free health check, offered to 21417 20-63-year-old employees of the Stockholm City and County Council in 1971-73, was accepted by 15903 persons. The examination included a multichannel chemical analysis of a single blood sample. Serum calcium levels greater than or equal to 11.0 mg/100 ml (2.75 mmol/l) and greater than or equal to 11.1 mg/100 ml (2.78 mmol/l) were encountered in 3.9% and 1.1% of the population, respectively. Among subjects below 50 years of age, the calcium concentration was significantly higher in males than in females. This difference disappeared in older subjects, essentially because the calcium level decreased with advancing age in the men. To a further investigation were invited 178 subjects with a single serum calcium registration greater than or equal to 11.1 mg/100 ml (2.78 mmol/l). Of this group, 95 persons (53.4%) exhibited hypercalcaemia (HC) on repeated testing. Twelve had been operated on prior to the actural follow-up and found to have parathyroid adenomata. Twenty subjects were on continuous treatment with diuretics of the thiazide type and seven had diseases that might induce HC (two had hyperthyroidism, two hypothyroidism, one sarcoidosis, one hypernephroma and one mammary carcinoma). In 56 patients the laboratory and physical examinations did not reveal any obvious cause for the HC except possible hyperparathyoidism (HPT). Eighty (84.2%) of the 95 HC subjects were women, mostly over 50 years. The 95 persons constituted 6% of the total number of health-screened persons. The highest prevalence, 13%, was recorded for women aged 60-63. The prevalence of HPT in the total material was 3.6%, which is higher than that found in several other studies. This is based on surgical findings to date.

Virtually any malignancy may lead to hypercalcemia, but carcinoma of the breast, myeloma, and carcinoma of the lung are especially frequent offenders. A more difficult diagnostic problem is posed by the "silent" tumor which secretes a substance causing hypercalcemia. Foremost in this category are bronchogenic carcimona and hypernephroma.

A patient with renal cell carcinoma and hypercalcemia was found to have suppressed serum parathyroid hormone levels but striking elevations of immunoreactive prostaglandins in plasma and metastatic tissue. It was hypothesized that prostaglandins may have either played a role in the hypercalcemia or were part of a counterregulatory event.

Nineteen patients were surgically treated for hyperparathyroidism associated with multiple endocrine neoplasia type 1 syndrome. Fourteen patients (74%) had removal of three or more parathyroid glands at the first operation, and five (26%) by removal of 2 1/2 or fewer glands. Two patients had recurrent hypercalcemia during the mean follow-up period of 65 months. One had a recurrence 10 years after subtotal parathyroidectomy. Reexploration in this patient revealed enlargement of the remaining tissue in the neck and an enlarged supernumerary gland in the aorticopulmonary window. The other patient had persistent hypercalcemia after removal of two hyperplastic parathyroid glands until after another 1 1/2 more glands were removed. After reoperation the patient was normocalcemic for 10 years before hypercalcemia was again noticed. The patient subsequently died from renal carcinoma metastases, which might have been the cause of the hypercalcemia before death.
