Question

The postoperative chemotherapy for pediatric pancreatic neuroendocrine tumor did not achieve the expected results. After the second round of chemotherapy, there was little change in the tumor size. Inquire about possible causes and treatment options.

Answer

The unclear effectiveness of chemotherapy may be due to tumor drug resistance, issues with the chemotherapy plan, or diagnostic errors. For constipation and anal pain, it is recommended to consume more fruits and vegetables, and yogurt to soften stools and alleviate pain.
