Gastrointestinal cancers are among the deadliest in the world. MACs for cancer clinic is considered to be the best cancer treatment clinic in Bangalore. dr. Sandeep Nayak is the founder of this state-of-the-art cancer treatment center with the latest technology, including a robotic surgery treatment center.
In 2016, colon and rectal cancer killed more people than breast, prostate, lung and liver cancers combined. The risk of developing gastrointestinal cancers is higher in people with a history of smoking or drinking alcohol or taking aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs). The risk is also higher in people with a history of Helicobacter pylori infection or chronic pancreatitis. The outlook for people with gastrointestinal cancers is very bleak. The 5-year survival rate is less than 10 percent in advanced stages. However, there are effective treatments that can improve the prognosis and quality of life of patients with gastrointestinal cancers.
In this article, Dr. Sandeep Nayak, one of the best oncologists in Bangalore, the different types of gastrointestinal cancers, the multiple stages of these cancers, the types of treatments available for these cancers at MACS for cancer clinic, and the survival of these patients.

What is Gastrointestinal Cancer?
Gastrointestinal cancers are cancers that arise in the digestive system. Most gastrointestinal cancers arise from the cells that line the lining of the intestines and stomach, but some can also arise from other parts of the digestive system.
What are the symptoms of gastrointestinal cancer?
Gastrointestinal cancers can manifest as indigestion, loose movements, vomiting, bloating, symptoms common with a stomach infection, or food poisoning. But if symptoms persist for more than a week, see a specialist immediately, says dr. Sandeep Nayak.
You can approach a gastroenterologist for a preliminary examination, which may include an endoscopy to determine the causes of your persistent digestive problems.
To confirm the presence of cancer, MRIs and other tests may be needed, including biopsies and markers in blood tests.
If symptoms worsen over time and you notice blood in your stool or vomit along with weight loss, anemia, and loss of appetite, you need to act in an emergency.
Stages of Gastrointestinal Cancer
Gastrointestinal cancer is a very broad term that can encompass many different types of cancer. The most common forms are colorectal, liver and stomach cancers.
Colorectal Cancer: Colorectal cancer is the second leading cause of death from cancer in India, with more than 40k cases detected every year. It is also the most common form of gastrointestinal cancer, accounting for about 50% to 60% of all cases. The 3 main stages for colorectal cancers are:
Stage I: confined to the innermost layer of cells lining the colon or rectum (the mucous membrane)
Stage II: Includes growth through the wall of the colon or rectum, but not through nearby tissues
Stage III: The growth has spread to nearby tissues such as lymph nodes, blood vessels, and organs near or in the abdomen that can affect vital functions, including the intestines, stomach, and liver
Grade 1: Lowest figure representing early cells with no significant change in cell appearance
Grade 2: Moderate changes in cellular structure, but inflammatory response is still low
Grade 3: Significant Structural Changes and Inflammatory Response
Grade 4: High-grade tumors resistant to treatment
What Causes Gastrointestinal Cancers?
dr. Sandeep Nayak explains that gastrointestinal cancers are caused by lifestyle choices such as smoking, drinking alcohol, and taking NSAIDs. They can also be caused by Helicobacter pylori infections and chronic pancreatitis.
Can gastrointestinal cancer be prevented?
dr. Sandeep Nayak is convinced that cancer can be prevented. He says some gastrointestinal cancers are preventable. For example, chronic pancreatitis can be prevented by limiting the use of alcohol and NSAIDs. Also, stomach cancer can be prevented by avoiding Helicobacter pylori infection.
In addition to the risk factors that can be reduced to reduce the risk of developing gastrointestinal cancers, if you have a family history of these cancers, it is recommended that you get screened for these diseases at an earlier age.
Types of Gastrointestinal Cancer
There are 3 main types of gastrointestinal cancers.
Stomach cancer: Stomach cancer is the most common type of gastrointestinal cancer. In India, more than 30,000 people develop stomach cancer every year, which is more than the number of people who develop colon and rectal cancer.
Colon cancer: Colon cancers affect the small intestine or colon. They include adenocarcinoma, lymphomas, and sarcomas. The prognosis for colon cancers is not as good as that of other types of gastrointestinal cancer, as it is challenging to diagnose early because of symptoms not specific to this type of cancer. For example, nausea and vomiting can be caused by a number of different conditions, including food poisoning or premenstrual syndrome (PMS).
Colorectal cancer: Colorectal cancers are the second most common type of gastrointestinal cancer after stomach cancer. Colorectal cancers affect the colon or rectum and are responsible for about a third of all gastrointestinal cancers worldwide. Although colorectal cancers usually have no symptoms in their early stages, they can eventually cause bleeding from the stool and blood in the stool or vomit. These symptoms should seek immediate medical attention as there is a high risk of colorectal cancers if these symptoms persist for more than 2 weeks.
Gastrointestinal Cancer Survival Rate
The 5-year survival rate in the advanced stages of gastrointestinal cancers is less than 10 percent. The outlook can be improved with the right treatments and early diagnosis.
The prognosis for people suffering from gastrointestinal cancer depends on the cancer type, stage and treatment method. Fortunately, there are many types of treatments and surgeries for this condition that provide an excellent prognostic outcome. For example, palliative chemotherapy offers a 50-70 percent cure rate for stage IV colorectal cancer in people over age 65. In certain cases, surgery may also provide long-term benefits for patients suffering from these cancers.
Surgical and Non-Surgical Treatments for Gastrointestinal Cancer
There are surgical and non-surgical treatments available for gastrointestinal cancers. For example, surgery is the standard treatment for colon cancer that is localized and has not spread to other parts of the body. There are also chemotherapy and radiation therapies that can treat these types of cancer.
Chemotherapy and radiation therapies are also available for patients with metastatic cancer. There is a difference between chemotherapy and radiation therapy when it comes to gastrointestinal cancers. Chemotherapy drugs are given as pills or liquids directly into the digestive tract through a tube (intravenous) or as suppositories that are inserted into the rectum (rectal). Radiation therapy usually involves a combination of X-rays, high-energy rays, and gamma rays delivered from an outside source to shrink the tumor.
The survival rate for gastrointestinal cancer varies depending on the type of cancer and the stage at which it is discovered – the earlier the cancer is found, the greater the chance of treatment.
If left untreated, gastrointestinal cancers can spread to other parts of the body. Early detection and treatment can help with your prognosis. If you experience symptoms, see a doctor and ask to be tested for gastrointestinal cancer.
