[Immunohistochemical evaluation of somatostatin receptor subtypes in surgical pathology specimens of neuroendocrine tumors].
The clinical development of specific/selective or more potent analogues of somatostatin has made the evaluation of somatostatin receptor subtypes in archival specimens or 10% formalin-fixed and paraffin-embedded specimens of neuroendocrine tumor (NET) critical to conferring the maximum clinical benefits on NET patients. Immunohistochemistry of somatostatin receptor subtypes could contribute to profiling their expression patterns in these patients. Therefore, surgical pathologists are expected to be asked to immunostain and evaluate somatostatin receptor subtypes in NET specimens in the near future by clinicians. However, there are problems associated with immunohistochemistry of somatostatin receptor subtypes, in particular with their evaluation and interpretation. Therefore, both pathologists and clinicians involved in the care or management of NET patients should be aware of the advantages and limitations of immunohistochemical evaluation of somatostatin receptor subtypes in order to achieve the most efficient treatment outcome for patients.
