My daughter, 13 years old, had pain in her right abdomen on November 22, 2011 and was hospitalized at Jiangxi Children’s Hospital and diagnosed with teratoma, then transferred to Shanghai Children’s Hospital for laparoscopic exploration + open retroperitoneal mass removal under anesthesia on December 17. The surgery was performed at Shanghai Children’s Hospital and the postoperative period was quite good in all aspects, but the pathology report results were not good. 1.According to the information you provided, the tumor type of the child is neuroendocrine tumor, which is a relatively rare tumor type, but since it is low grade, the malignancy degree is relatively low and the prognosis is relatively better. 2.I don’t know the specific invasion range of the tumor, we suggest you to have PET-CT examination of your child to exclude whether there is still tumor residue or whether there are distant metastases. 3.In terms of treatment, surgery is the only curative treatment mode at present, if the surgery is complete, it is possible to obtain a cure. Even for incurable patients, surgery still has the function of reducing the load of the tumor and reducing intestinal obstruction. 4. The treatment after surgery depends on the specific situation. For gastroenteropancreatic endocrine tumors, growth inhibitor therapy is the main treatment for symptom control, and drugs include lanreotide (1 injection every 2 weeks), lanreotide Autogel (1 injection per month) and octreotide acetate microspheres (Sunlong, 1 injection per month). 5, Other drug treatments include interferon, either alone or in combination with growth inhibitors (the latter more common). 6. Chemotherapy: For most neuroendocrine tumors, the exact therapeutic value of chemotherapy is uncertain, especially for well-differentiated, slow-growing tumors. However, if it is a neuroendocrine tumor of the pancreas, it is often sensitive to chemotherapy and can be used. 7. Others: Radionuclide therapy, mainly used for tumor residual or the presence of metastasis.
