Parathyroid hormone-related protein measured at the time of first visit is an indicator of bone metastases and survival in lung carcinoma patients with hypercalcemia

BACKGROUND Parathyroid hormone‐related protein (PTH‐rP) is a major cause of tumor‐induced hypercalcemia (TIH) and frequently is found to be elevated in serum of patients with TIH. In the current study, the authors examined the usefulness of PTH‐rP measurement at the time of first presentation in the follow‐up of lung carcinoma patients with TIH. METHODS The authors retrospectively studied 23 of 1149 lung carcinoma patients who were found to have...
