Gastrointestinal Oncology

Gastrointestinal oncology is a branch of oncology that deals with the diagnosis and treatment of cancers of the gastrointestinal tract, including the stomach, small intestine, colon, and rectum. Gastrointestinal cancers are the third most common type of cancer, and they are the leading cause of cancer-related death in men and women in the United States. Gastrointestinal cancers can be divided into two main types: gastric cancer and colorectal cancer. Gastric cancer is the most common type of gastrointestinal cancer, and it accounts for about 60% of all gastrointestinal cancers. Colorectal cancer is the second most common type of gastrointestinal cancer, and it accounts for about 30% of all gastrointestinal cancers. Other types of gastrointestinal cancer include pancreatic cancer, hepatocellular cancer, and biliary tract cancer. Gastrointestinal cancer is typically diagnosed when it has advanced beyond the early stage, which is known as Stage I. Stage I gastric cancer is generally treated with surgery, chemotherapy, and radiation. Stage II gastric cancer is treated with surgery, chemotherapy, and radiation. Stage III gastric cancer is treated with surgery, chemotherapy, and radiation. Stage IV gastric cancer is generally treated with chemotherapy and radiation. Stage IV gastric cancer is rarely treated with surgery. Gastrointestinal cancer can be highly responsive to treatment, and most patients who are treated will survive for at least five years. However, gastrointestinal cancer is one of the most deadly types of cancer, and the five-year survival rate for patients who are treated is only about 60%. There are many different types of gastrointestinal cancer, and each type of gastrointestinal cancer is treated differently. However, the majority of gastrointestinal cancers are treated using a combination of surgery, chemotherapy, and radiation.
