We also sought to determine whether SSTs could serve as tumor markers in the differential diagnosis of typical parathyroid adenomas, atypical adenomas and carcinomas, perhaps as additive PC immunohistochemistry panel markers to the previously established parafibromin, Ki-67, galectin 3 and protein gene product 9.5 (PGP9.5) (15). The gene discussed is UCHL1; the disease is neoplasm.
