I. Western Medical Treatment

(1) Surgical Treatment

Early gastric cancer should undergo radical resection; for mid-to-late stage gastric cancer without distant metastasis, surgery should still be pursued to remove as much of the lesion as possible; for late-stage gastric cancer with pyloric obstruction, gastrojejunostomy can be performed to address difficulties in eating and taking medication.

(2) Chemotherapy

Suitable for pre-, intra-, and post-operative periods, as well as for advanced gastric cancer that cannot undergo surgery, often using multi-course combination therapy. There are many chemotherapy regimens, commonly MFC regimen: 5-fluorouracil 500 mg added to 250 ml of 5%–10% glucose or normal saline for intravenous drip; cytarabine 50 mg added to 20 ml of normal saline for intravenous push; mitomycin 4 mg dissolved in 20–40 ml of normal saline, diluted and immediately injected intravenously, twice a week, totaling 8–10 sessions per course. FAMT regimen: 5-fluorouracil 2000 mg, cyclophosphamide 200 mg, mitomycin 2 mg, bleomycin 0.5 mg, administered once or twice a week, with 8 sessions constituting one course. Intervals between courses depend on the body’s response. Generally, post-surgical chemotherapy recommends 3 courses in the first year, 2 courses in the second year, and 1 course in the third year. Blood counts should be monitored regularly during chemotherapy.

(3) Radiotherapy

Both cobalt-60 and linear accelerators can be used for treatment, with significant efficacy for localized lesions; combined with TCM tonifying and strengthening treatment, the results can be even more satisfactory.

(4) Immunotherapy

Cancer cells are used to produce immune vaccines and immunostimulants, thereby enhancing patients' specific immunity against cancer. Tumor-specific immunoribonucleic acid, alpha interferon, LAK cell preparations, interleukin-2, and other agents can also be tried.
