What Is the Prognosis for Cancer in the Omentum?
Cancer of the omentum is linked to ovarian cancer, which generally has a 45 percent survival rate after 5 years, according to the American Cancer Society. In 80 percent of ovarian cancer patients the disease has spread to the omentum before the condition is diagnosed, the University of Chicago Medical Center says.
The omentum is a pad of fat cells that covers the stomach and intestines, the University of Chicago Medical Center states. Ovarian cancer tends to spread to the omentum quickly.
When ovarian cancer has spread to the abdomen, it is considered the beginning of Stage III, according to the American Cancer Society. The survival rate for women with Stage IIIA epithelial ovarian cancer is 59 percent after 5 years. Chances of survival are lower if the cancer has spread further. Women who are diagnosed before age 65 tend to have a better prognosis.
Survival rates are determined by outcomes of large populations, and outcomes vary from person to person, the ACS says. A variety of factors determine ovarian cancer survival, including the type of treatment, how well the cancer responds to it and pre-existing conditions that may affect the patient's overall health. The patient's physician can better determine long-term prognosis based on these factors.
