Alterations in Calcium Metabolism in Cancer Patients Treated with 6-Diazo-5-Oxo-L-Norleucine.

Summary Ten patients with hypercalcemia and hypercalcuria and 1 patient with normocalcemia and hypercalcuria were treated with 6-diazo-5-oxo-L-norleucine alone or in combination with 6-mercaptopurine. Full correction of hypercalcemia with treatment occurred in 8 of 13 instances in these patients. Correction of hypercalcuria was observed in 9 of 14 instances. Various possible mechanisms underlying these observed effects are considered.

Documented hyperparathyroidism of thirty‐six years' duration

The fascinating history of the first Memorial Hospital patient who was diagnosed as having hyperparathyroidism is reviewed. The illness presented as a cystic mass in a femur in 1929, which was treated with radiation. When the patient was first seen at Memorial Hospital in 1931, the diagnosis of osteitis fibrosa cyetica was made; serum calcium was 14 mg/100 ml. In 1932, 6 years after Mandl performed the first parathyroidectomy ever for osteitis fibrosa cystica, this patients neck was explored, and a right hemithyroidectomy was done, with removal of two normal parathyroid glands. The parathyroid tumor was finally located and partially removed in 1937 after a second failure at neck exploration in 1936. Correspondence between Dr. Edward D. Churchill at the Massachusetts General Hospital and Dr. Bradley Coley at Memorial Hospital indicated the concern at that time about uncontrollable tetany, which had been fatal i n some contemporary cases and which had led to the practice of only partially removing the tumor. Following this, the patient was observed with documented hypercalcemia and chemical evidence of hyperparathyrodism until age 79. The physical and chemical abnormalities over the years up to and including her last exam are presented. The case is important not only from the historical viewpoint, but because it lends a perspective to long‐term parathyroid disease, which is becoming less appreciated in this day of the routine serum calcium by SMA‐12 screening. The question of partial parathyroidectomy for adenoma or hyperplasia is reviewed, and the question of observation of patients with mild hypercalcemia who probably have parathyroid tumors is discussed.
