GI tract including pancreas is the one of most common primary sites of neuroendocrine tumors. Current grading of neuroendocrine tumors are based on the 2010 WHO classification. This classifies grade 3 tumors as the neuroendocrine tumor with mitosis > 20 per 10 high power field or Ki-67 labeling index > 20%. Etoposide-based chemotherapy, mostly as the combination with cisplatin, has been the mainstay of the treatment for patients with grade 3 neuroendocrine tumors. However, a recent large retrospective analysis has suggested this regimen may not be effective in relatively low Ki-67 labeling index. Therefore, the investigators designed a clinical trial testing temozolomide-capecitabine combination, which has been mostly investigated in well differentiated (ie., grade 1 or 2) neuroendocrine tumors, in patients with grade 3 and low Ki-67 gastroenteropancreatic neuroendocrine tumors.

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
