About Gastric (Stomach) Cancer Stage 2

Overview

Stage 2 gastric cancer refers to a specific stage of gastric cancer where the cancer has grown beyond the inner layer of the stomach wall (mucosa) and may have invaded the deeper layers of the stomach wall (submucosa).

Staging is based on TNM classification, which 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 2, the cancer has not spread to nearby lymph nodes or other organs. Stage 2 gastric cancer is further divided into Stage 2A and Stage 2B, based on factors such as tumor size and lymph node involvement. Treatment options for Stage 2 gastric cancer may include surgery, radiation therapy, chemotherapy, or a combination of these approaches. It is important to consult with a healthcare professional to discuss individualized treatment options and potential side effects.

Causes and Risk Factors

There is no known cause for gastric cancer. However, there are known risks identified and it is known that gastric cancer development is influenced by a combination of various factors, including:

• Helicobacter pylori infections: This bacterium is a major risk factor for gastric cancer.
• Smoking: Tobacco use increases the risk of developing gastric cancer.
• Surgical history of partial gastrectomy: Previous surgery to remove part of the stomach may increase the risk.
• Menetrier’s Disease and atrophic gastritis: These conditions are associated with an increased risk of gastric cancer.

The non-modifiable risk factors for Stage 2 gastric cancer are factors that cannot be changed. These include:

• Age: Increasing age is a significant risk factor for gastric cancer.
• Genetic predispositions: Positive family history of gastric cancer and other related cancers cluster can increase the risk.
• Previous history of polyps: Individuals with a history of polyps in the stomach may have an increased risk.

The modifiable risk factors for Stage 2 gastric cancer are factors that can be changed and influenced. These include:

• Poor dietary habits: Unhealthy eating patterns, such as a diet high in processed foods and low in fruits and vegetables, can increase the risk.
• Low physical activity: Lack of regular exercise or sedentary lifestyle can contribute to the development of gastric cancer.
• Obesity: Being overweight or obese is associated with an increased risk.
• Heavy alcohol consumption: Excessive alcohol intake is a modifiable risk factor for gastric cancer.

It's important to note that these risk factors are not specific to Stage 2 gastric cancer but can contribute to the development and progression of the disease in general. It's always advisable to consult with a healthcare professional for personalized advice and guidance regarding specific risk factors and treatment options.

Symptoms

In the early stages of Stage 2 gastric cancer, there may not be obvious clinical symptoms. However, as the tumor grows, certain symptoms may become more apparent. The most common early symptoms of Stage 2 gastric cancer include:

• Upper abdominal pain
• Fullness after eating
• Indigestion
• Bloating and discomfort in the stomach
• Nausea and loss of appetite
• Heartburn

As gastric cancer progresses to later stages or higher severity, additional symptoms may occur. These can include:

• Vomiting
• Difficulty swallowing
• Stomach pain
• Abdominal swelling
• Blood in the stool
• Unintentional weight loss
• Tiredness or weakness
• Yellowing of the skin and eyes (jaundice)
• Swelling of the lymph nodes

It's important to note that these symptoms can also be caused by other conditions, so it's essential to consult with a healthcare professional for an accurate diagnosis. They can perform tests to determine if gastric cancer is present and at what stage. Treatment options can then be discussed based on the diagnosis.

Diagnosis

To diagnose Stage 2 gastric cancer, the following examinations, tests, and procedures are commonly performed:

• Medical history review: Doctors will assess any observable signs and symptoms and inquire about a family history of cancer.
• Physical exam: A healthcare professional will conduct a physical exam to check for tenderness, swelling, typical bowel sounds, and lumps.
• Blood tests: These may include a complete blood count, liver function tests, and tumor marker blood tests to evaluate overall health and detect any abnormalities.
• Stool tests: Fecal occult blood tests or fecal immunochemical testing can be done to check for the presence of blood in the stool.
• Imaging tests: CT scans are commonly used to create a 3D image of the stomach and determine the size of the tumor. This test can identify abnormalities such as masses or thickening of the stomach wall.
• Upper gastrointestinal endoscopy with biopsy: This is considered the gold standard for diagnosing gastric cancer. It involves inserting a flexible tube with a camera into the stomach to examine the lining and take tissue samples (biopsy) for further analysis.

Additional examinations, tests, and procedures to determine Stage 2 gastric cancer may include:

• Pathological examination: A biopsy of the tumor is performed to examine it under a microscope and confirm the diagnosis.
• Diagnostic laparoscopy: This minimally invasive procedure allows doctors to examine the abdomen and surrounding organs for signs of cancer spread.
• Diagnostic intra-peritoneal fluid examination: Fluid samples from the abdominal cavity can be analyzed for cancer cells.
• Thoracic, abdominal, and pelvic CT scans: These scans help determine if cancer has spread to nearby lymph nodes or other organs.
• Magnetic resonance imaging (MRI): An alternative to CT scans, MRI can provide detailed images of liver, peritoneal, and systemic metastases.
• Positron emission tomography (PET) scan: This imaging test can detect cancer cells that have spread beyond the stomach.

Remember, these are general procedures used in diagnosing Stage 2 gastric cancer. The specific diagnostic approach may vary depending on individual cases. It is important to consult with your healthcare professional for personalized advice.

Treatment Options

The goals of treatment for Stage 2 gastric cancer are to remove the tumor and prevent its spread, as well as to improve survival rates and maintain quality of life. The following treatments and interventions may be used:

• Surgical resection: The main treatment for Stage 2 Gastric Cancer is surgical removal of the tumor. This involves removing the affected part of the stomach and nearby lymph nodes. The goal is to achieve radical resection, eliminating the tumor and ensuring clear surgical margins.
• Neoadjuvant chemotherapy: This type of chemotherapy is given before surgery to shrink the tumor and make it more operable.
• Adjuvant chemoradiation therapy: Radiation therapy combined with chemotherapy after surgery may be recommended to kill any remaining cancer cells and reduce the risk of recurrence.
• Lifestyle changes: Adopting a healthy lifestyle can support treatment outcomes. This includes:
  • Maintaining a balanced diet
  • Engaging in regular physical activity
  • Quitting smoking
  • Limiting alcohol consumption

It's important to note that specific medication types or regimens may vary depending on individual patient factors. Treatment decisions should be made in consultation with a multidisciplinary team of healthcare professionals. Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
