In stage 3 stomach cancer with 3 lymph nodes infected margin clear what is the survival rate with treatments of both chemo and radiation?

Odds: I'm going to assume this is a stage iiia, perhaps with tumor in the submucosa and three positive lymph nodes. The older statistics cite at least a 20% 5-year survival, and i've seen other numbers that are more encouraging. It will depend some on the histologic type and your physician can give you an estimate of your personal odds. Good luck.

Usually poor, sorry: Odds are not in ur favor given node involvement. U r looking at less than 20 %. I would definitely talk to oncologist to get better idea. You have to consider ur age, functional status, side affects from chemo and what u want out of life before consenting to chemo. Usually not role for radiation. Also, just because u start chemo doesn't mean u have to finish if the side effects are terrible.

Depends-improving : Studies have shown clear benefit with adjuvant chemo radiation following surgery in intergroup study. "classic" trial from korea showed benefit using just chemo alone. For her-2 neu + tumors, Herceptin (trastuzumab) adds benefit. The type of gastric cancer, the type of surgery, and the histology all impact on the outcome. Please discuss with an oncologist experienced and knowledgeable about gastric cancers.

Yes.: Radiation therapy has been shown to improve survival in combination with chemotherapy after surgery for stomach cancer. Your local board-certified radiation and medical oncologists can provide more detailed explanations.
