A study on the pathological indices reports of neuroendocrine tumors registered in Shahid Sadoughi Hospital, Yazd from 2011 to 2015 and comparing it with standard pathological indices

Neuroendocrine tumors (NETs) originate from peptide and amine producing cells of neuroendocrine system. Data presented in pathology reports, determine the prognosis and therapeutic approach of patients. The aim of this study was to investigate that how these indicators are reported in Shahid Sadoughi Hoaspital.

In this cross-sectional and descriptive study, all neuroendocrine tumors reported by pathology department of Shahid Sadoughi Hospital, were studied by census method from 2011 to 2015. Finally, 73 cases were studied regarding pathologic standard indices including pathology diagnosis, anatomic origin of the tumor, amount of mitosis, immunohistochemical staining, immunohistochemical staining type, determination of Ki67 index, the status of necrosis, vascular and perineural invasion.

Among 73 investigated pathology reports, small cell carcinoma was the most common pathologic diagnosis with 46.6% of cases. The most common anatomic site was respiratory system with 49.3% of cases. Amount of mitosis, Ki67 index, the status of necrosis and vascular, perineural invasion were mentioned in 31.5%, 28.8%, 34.2% and 15.1% of pathology reports respectively.

According to the results, most pathologic reports of neuroendocrine tumors lack one or more factors that is necessary for reporting. However, these factors are pivotal for determination of prognosis and therapeutic approach in patients.
