Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are the most prevalent type of neuroendocrine tumors. Limited data is available on GEP-NET in Thai patients. Proliferative index as determined by mitotic rate/index (MI) and Ki-67 labelling index have proven to be strong prognostic factors in GEP-NETs and many experts have recommended that both markers be performed in all cases although this is not accepted universally. Ki-67 is not widely available and/or standardized in Thailand. Therefore, this study aimed to explore the agreement of these 2 methods and their correlation with survival in our center.
