The next steps are to decide whether or not the patient is a good candidate for major surgery. Then after that, after you think the patient may be a candidate, you want to do scans, typically CAT scans of the chest, abdomen and pelvis, to make sure there's no evidence that the cancer has already spread.
ANNOUNCER: A cancer specialist called an oncologist will then rate how far the disease has progressed.
JOHN MACDONALD, MD: Like many cancers, it's important to understand the stages of stomach cancer, because that gives you some information on prognosis. The earliest stage is when the tumor is just in the stomach and hasn't spread into the wall of the stomach and that would be called a stage I. As the tumor spreads through the wall of the stomach, you get to stage II. When you begin to have lymph node involvement, you get to stage III. And if the tumor spreads to other organs, you have stage IV stomach cancer.
ANNOUNCER: Early stage gastric cancer can often be cured.
JOHN MACDONALD, MD: Gastric cancer can definitely be cured, if it's caught early enough. If you look at patients sort of across the board who have stomach cancers, and when they're surgically removed there's no involvement of the lymph nodes, then at least 50 percent of those patients are cured with the surgery alone.
MANISH A. SHAH, MD: Surgery for stomach cancer comes in two main forms. One is a total gastrectomy, which is a removal of the entire stomach, or a partial gastrectomy, which is removing part of the stomach. The partial gastrectomy is known also as a subtotal gastrectomy, less than total.
ANNOUNCER: For early stage gastric cancer, surgery is considered the main treatment. But not for later stages when the cancer has spread to other organs.
MANISH A. SHAH, MD: For stage IV stomach cancers, we think of chemotherapy as the main treatment. There are many different types of drugs that are chemotherapy that are active in the disease. Just to name a few drugs that we think of currently: cisplatin; fluorouracil; docetaxel, which is also known as Taxotere; and irinotecan, which is also known as Camptosar or CPT-11.
So the good news is that there are many different drugs that are active. We've historically combined the drugs into combinations of either two or three drugs, and the effectiveness of two or three drugs is much better than one and we're learning how to manage the side effects so that people can both treat the cancer but maintain a quality of life.
