Primary hyperparathyroidism and malignancy: "studies by nature"
Abstract
The American Food and Drug Administration approval of parathyroid hormone (PTH) administration for osteoporosis as well as the possibility for its future therapeutic applications requires an examination of the suggested association between PTH and cancer, particularly osteosarcomas. The objective was to evaluate such a connection by collecting observational data from two groups of patients, designated as "studies by nature". Cohort 1: Medical records of all patients with primary hyperparathyroidism that were treated in a referral center during a 12-year period were retrospectively reviewed for malignancy before, at the time or after diagnosis. Cohort 2: Records of patients with osteosarcomas that were treated in referral centers during 15 years were retrospectively reviewed for hyperparathyroidism, as indicated by history or laboratory results. There were 582 patients with primary hyperparathyroidism. While 56 (9.6%) had malignancy, 47 (8%) developed cancer after diagnosis with hyperparathyroidism during 6.1 years of documentation. This rate did not exceed the incidence of developing cancer among the general population. Although thyroid cancer was about 4 times the incidence in the general population, this may be attributed to ...Continue Reading

Cancer Incidence & Mortality
Cancer has emerged as a global concern due to its increase in incidence and mortality. Efforts are underway to evaluate and develop action plans to reduce the global burden of cancer. Currently, lung cancer, breast cancer and prostate cancer are the leading causes of cancer mortality. Here is the latest research on cancer incidence and mortality.
