The main Gastric Cancer Therapeutics is surgical resection because it provides the only chance of recovery. The total, subtotal, or distal gastrectomy are the most popular surgeries. The capacity to establish clear microscopic margins determines the procedure to use and the degree of nodal dissection. Removal of affected neighbouring organs, such as the spleen, may be necessary in individuals who have regionally advanced illness. The use of neoadjuvant chemotherapy in the Gastric Cancer Therapeutics is well-established. For localised gastric cancer, perioperative chemotherapy or postoperative chemotherapy plus chemoradiation are preferable.
Molecular testing of the HER-2 status (expression and amplification) should be carried out at the time of Gastric Cancer Therapeutics evaluation for aGC, initially by immunohistochemistry and then FISH in case of a 2 + score. Immunohistochemistry (IHC) or PCR-based techniques should be used to examine predictive indicators for immunotherapy, such as MSI-h/mismatch-repair deficiency (MMR-d), and in situ hybridization should be used to determine EBV status.
