Patient identification. There were 2900 and 2453 gastrointestinal neuroendocrine tumors (GI NET) patients who also had a claim for pharmacologic treatment between 7/1/2009 and 6/30/2014 in the MarketScan and PharMetrics databases, respectively. After excluding patients who had treatment during a 6-mo pre-index period (and therefore were considered to be continuing, rather than initiating, treatment); received treatment before receiving a diagnosis of GI NET; were < 18 yr old; or were not continuously enrolled in the 6-mo pre-index period, there remained 2258 newly treated GI NET patients who were included in the study. ¹Somatostatin analogues (SSAs), targeted therapy, cytotoxic chemotherapy, or interferon; ²324 (34.8%) within 3 mo, and 516 (55.4%) within 6 mo; ³249 (35.0%) within 3 mo, and 380 (53.4%) within 6 mo.
