Testing the Use of Chemotherapy After Surgery for High-Risk Pancreatic Neuroendocrine Tumors
Trial Parameters
Brief Summary
This phase II trial studies the effect of capecitabine and temozolomide after surgery in treating patients with high-risk well-differentiated pancreatic neuroendocrine tumors. Chemotherapy drugs, such as capecitabine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving capecitabine and temozolomide after surgery could prevent or delay the return of cancer in patients with high-risk well-differentiated pancreatic neuroendocrine tumors.
Eligibility Criteria
Inclusion Criteria: * Participants must have a histologic diagnosis of well-differentiated pancreatic neuroendocrine tumor (pNET) that was resected between 14 and 120 days prior to registration. Participants must have a scan within 90 days prior to registration without evidence of metastatic disease. Acceptable scans are multiphase computed tomography (CT) abdomen, magnetic resonance imaging (MRI) with intravenous (IV) contrast of the abdomen, or positron emission tomography (PET)-CT DOTATATE imaging if the DOTATATE PET-CT included IV iodine contrast for the CT portion of the exam * Resection must have been an R0 or R1 per treating investigator's assessment and/or pathology report * Ki-67 testing, which is considered part of standard of care in the pathology report, must have been performed between 14 and 90 days prior to registration and the result must be \>= 3% and =\< 55%. Treating investigators are encouraged to contact the S2104 Study Chairs and/or the study pathology chair with
