Data including demographic data, history of cancer, size of adenoma (micro or macro), serum IGF-1 and GH levels at the time of diagnosis, serum prostate-specific antigen (PSA), thyroid ultrasonography, and, if needed, thyroid fine needle aspiration cytology (TFAC), colonoscopy, and mammography results were collected from patient records retrospectively. Here, IGF1 is linked to adenoma.
