About Gastric (Stomach) Cancer Stage 1
Gastric cancer, also known as stomach cancer, is a type of cancer that starts in the cells lining the stomach. It is a malignant tumor that can invade nearby tissues and spread to other parts of the body. Stage 1 gastric cancer refers to an early stage of the disease where the primary tumor has grown from the top layer of the stomach wall into the underlying tissue.
Staging is based on TNM classification.
TNM classification system is a way for doctors to stage many different types of cancer.
- T describes the original (primary) tumor
- N tells whether the cancer has spread to the nearby lymph nodes
- M tells whether the cancer has spread (metastasized) to distant parts of the body
The staging system for gastric cancer helps healthcare professionals determine the extent of the disease and plan appropriate treatment.
In Stage 1, the tumor may have also spread to one or two nearby lymph nodes, or it may have grown more deeply into the stomach wall without affecting the lymph nodes. The main treatment for Stage 1 gastric cancer is surgery to remove all or part of the stomach. In some cases, chemotherapy may be recommended after surgery. The outlook for Stage 1 gastric cancer is generally favorable, as many cases can be successfully treated. It's important to consult with a healthcare professional for personalized advice on treatment options and prognosis.
Gastric cancer occurs when there is a growth of cells that starts in the stomach. Gastric cancer development can be influenced by a combination of genetic and environmental factors.
The non-modifiable risk factors for Stage 1 gastric cancer are factors that cannot be changed. These include:
- Age: The likelihood of being diagnosed with gastric cancer increases with age.
- Genetic factors: Mutations in genes such as MLH1, MSH2, and APC can contribute to the development of gastric cancer.
The modifiable risk factors for Stage 1 gastric cancer are factors that can be changed or influenced. These include:
- Helicobacter pylori infection: This bacterial infection is a known risk factor for gastric cancer.
- Smoking: Tobacco smoking has been associated with an increased risk of gastric cancer.
- Dietary factors: Certain dietary habits, such as high intake of dietary sodium and low intake of fruits and vegetables, may increase the risk of gastric cancer.
- Alcohol consumption: Heavy alcohol consumption has been linked to an increased risk of gastric cancer.
It's important to note that these risk factors are not exclusive to Stage 1 gastric cancer and can apply to other stages as well. It is always recommended to consult with a healthcare professional for personalized advice on risk factors and preventive measures.
In the early stages of Stage 1 gastric cancer, symptoms may not be noticeable. However, when symptoms do appear, they can be vague and similar to other digestive issues. The most common early symptoms of Stage 1 gastric cancer include:
- Indigestion
- Stomach discomfort or pain
- Feeling full quickly when eating
- Bloating or frequent belching
- Mild nausea
- Reduced appetite
- Heartburn
As gastric cancer progresses or reaches a higher severity, additional symptoms may occur. These can include:
- Unexplained weight loss
- Vomiting blood
- Fatigue
- Weakness
- Jaundice (yellowing of the eyes and skin)
- Blood in the stool
It is important to see a doctor if you experience these symptoms, especially if they are recurring or do not go away. Early diagnosis and treatment can improve outcomes.
To diagnose Stage 1 gastric cancer, the following examinations, tests, and procedures are commonly performed:
- Complete physical examination: This includes a thorough assessment of your medical history, symptoms, and physical signs.
- Blood chemistry tests: These tests evaluate your overall health and check for any abnormalities.
- Upper gastrointestinal endoscopy: This procedure involves the use of a flexible tube with a camera to examine the inner lining of your stomach and collect tissue samples (biopsy) for further analysis.
- Imaging tests: These may include thoracic, abdominal, and pelvic computed tomography (CT) scans to assess the extent of the tumor and check for any spread to nearby lymph nodes or organs.
To determine Stage 1 gastric cancer, additional examinations, tests, and procedures may be recommended:
- Endoscopic ultrasound (EUS): This procedure uses sound waves to create detailed images of the layers of your stomach wall and nearby lymph nodes.
- Fine-needle biopsy: During EUS, a thin needle may be used to extract tissue samples from suspicious areas for further analysis.
- Diagnostic laparoscopy: This minimally invasive surgery allows doctors to directly visualize the inside of your abdomen and check for any spread of cancer.
- Diagnostic intra-peritoneal fluid examination: If there is suspicion of cancer spread within the abdomen, a sample of fluid may be collected and analyzed.
The primary goal of treatment for Stage 1 gastric cancer is to cure the disease by removing the tumor and preventing its spread. The recommended treatment options for Stage 1 Gastric Cancer include:
- Surgery: The main treatment for Stage 1 gastric cancer is surgery. This may involve removing part of the stomach (subtotal gastrectomy) or the entire stomach (total gastrectomy). If nearby lymph nodes are affected, they will also be removed. Surgery aims to remove the tumor and any potentially cancerous cells.
- Endoscopic surgery: In very early-stage a surgeon may perform the surgery using an endoscope, which is a thin tube inserted through the throat into the stomach. This minimally invasive approach allows for removal of the tumor from the stomach lining.
- Neoadjuvant chemotherapy: In some cases, where surgical resection is not possible, neoadjuvant chemotherapy may be recommended. This type of chemotherapy is given before surgery to shrink the tumor and make it more operable.
- Adjuvant chemotherapy: After surgery, adjuvant chemotherapy may be recommended to kill any remaining cancer cells and reduce the risk of recurrence.
- Targeted therapy: Targeted therapies are medications that specifically target certain molecules or pathways involved in cancer growth. They can help slow down or stop the growth of g astric cancer cells.
- Immunotherapy: Immunotherapy uses the body's immune system to fight cancer cells. It can help boost the immune response against g astric cancer and improve treatment outcomes.
It's advisable to consult with your healthcare professional for personalized treatment recommendations and more information about potential additional treatments that may be beneficial in your individual case.
