Kasajima A, et al. - The authors undertook an exploratory study of the high interlaboratory and interobserver agreement of somatostatin receptor immunohistochemical analysis in patients with neuroendocrine neoplasms. The results illustrated a positive link with clinical efficacy to somatostatin analogs, as well as simple and widespread use. Hence, HER2-Score could serve as a standard evaluation procedure of somatostatin receptors 2A (SSTR2A) and 5 (SSTR5) expression in neuroendocrine neoplasms.
