Also suggest the next course of treatment
[|AI|]  Hello;Gastric carcinoid is low grade tumor meaning it is slow growing tumor compared to typical carcinoma. They have long course and are less responsive to traditional anti-cancer therapy like radiotherapy and chemotherapy. Somatostatin analogues like octreotide LAR have been utilized to reduce the gastrin/hromogranin levels and have been shown to reduce recurrences, yet its use is not routine. You can discuss with your oncologist regarding this therapy. Another option is wait and watch with periodic DOTA-scan. Wish you good health.
