Gastric cancer, also called stomach cancer, develops when abnormal cells in the stomach lining begin to grow uncontrollably. The most common type is gastric adenocarcinoma, although other, less common types can also occur.
A diagnosis of stomach cancer can be overwhelming, but treatment has advanced considerably. The appropriate approach depends on the cancer’s location, stage, cell type, biomarkers, overall health, and whether it has spread beyond the stomach. Treatment may involve surgery, chemotherapy, targeted therapy, immunotherapy, radiation therapy, or a combination of these approaches.
For patients looking for Gastric Cancer Treatment in Delhi, early evaluation by an experienced gastrointestinal oncology team can help establish an accurate diagnosis and determine whether the disease can be treated with curative intent.
Symptoms and Causes of Gastric Cancer
Symptoms of Gastric Cancer
Gastric cancer may not cause obvious symptoms in its early stages. Some early complaints can resemble common digestive problems, which may delay evaluation. Symptoms that persist or progressively worsen should not be ignored.
Common symptoms include:
- Persistent indigestion or discomfort in the upper abdomen
- Frequent bloating after eating
- Loss of appetite
- Unexplained weight loss
- Nausea or vomiting
- Feeling full after eating only a small amount
- Abdominal pain
- Difficulty swallowing when the tumor is near the junction of the stomach and esophagus
- Weakness or fatigue, sometimes related to anemia
- Blood in the stool or vomiting blood in more advanced cases
Having these symptoms does not automatically mean that a person has gastric cancer. However, persistent symptoms, particularly unexplained weight loss, bleeding, anemia, or progressive difficulty eating, warrant medical assessment.
Causes and Risk Factors
The exact cause of gastric cancer is not always identifiable. Several factors can increase the risk, including:
- Helicobacter pylori (H. pylori) infection
- Chronic inflammation of the stomach
- Smoking
- A diet high in certain preserved or smoked foods
- Family history of gastric cancer
- Certain inherited genetic conditions
- Previous stomach surgery in some patients
- Certain types of gastric polyps
- Increasing age
Risk factors do not mean that a person will definitely develop cancer. Likewise, gastric cancer can occur in people without obvious risk factors.
Diagnosis and Staging
Accurate diagnosis is essential before selecting Gastric Cancer Treatment in Delhi or elsewhere. A doctor generally begins with a detailed medical and family history, physical examination, and appropriate investigations. Blood tests may be performed to identify anemia or other abnormalities.
Upper GI Endoscopy and Biopsy
An upper gastrointestinal endoscopy allows a specialist to directly examine the esophagus, stomach, and duodenum. If an abnormal area is identified, a biopsy can be taken for laboratory examination. A biopsy is generally essential for confirming gastric cancer.
Imaging and Staging
After confirmation, additional tests may be recommended to determine the extent of disease. Depending on the individual case, these can include:
- Contrast-enhanced CT scans
- PET-CT in selected situations
- Endoscopic ultrasound
- MRI in selected circumstances
- Diagnostic laparoscopy for certain locally advanced cancers
Staging determines whether the tumor is confined to the stomach, involves nearby lymph nodes, or has spread to distant organs. This information is critical because treatment for localized disease can differ significantly from treatment for metastatic disease.
Biomarker Testing
Modern gastric cancer care increasingly uses tumor biomarkers to help personalize treatment. Depending on the cancer, testing may include HER2, PD-L1, mismatch repair (MMR)/microsatellite instability (MSI), tumor mutational burden, and other relevant markers.
This information can help doctors determine whether targeted medicines or immunotherapy may be appropriate.
Treatment, Benefits and Recovery
The treatment plan for gastric cancer should be individualized. A multidisciplinary team may include a surgical gastroenterologist or gastrointestinal oncologic surgeon, medical oncologist, radiation oncologist, gastroenterologist, radiologist, pathologist, dietitian, and other specialists when required.
Early Stage Gastric Cancer Treatment
Early Stage Gastric Cancer Treatment may offer the possibility of long-term disease control or cure when the cancer is detected before significant spread.
For carefully selected early tumors, an endoscopic procedure such as endoscopic mucosal resection (EMR) may be appropriate. Other patients may require partial or total gastrectomy with removal of regional lymph nodes.
The choice depends on factors such as tumor size, depth of invasion, location, histological characteristics, and risk of lymph-node involvement.
Surgery for Gastric Cancer
Surgery remains an important treatment for resectable gastric cancer. Depending on tumor location and extent, surgery may involve:
- Partial/distal gastrectomy – removal of part of the stomach
- Total gastrectomy – removal of the entire stomach when required
- Regional lymph-node dissection
- Reconstruction to restore continuity of the digestive tract
For stage II and III disease, surgery is often considered alongside perioperative or postoperative systemic treatment.
Chemotherapy, Targeted Therapy and Immunotherapy
Chemotherapy may be recommended before surgery, after surgery, or as the principal treatment for advanced disease.
For some patients with advanced gastric cancer, biomarker results can help identify candidates for targeted therapy or immunotherapy. For example, HER2 status, PD-L1 expression, and MSI/MMR status can influence treatment decisions.
Radiation Therapy
Radiation therapy may be considered in selected situations, particularly depending on tumor location, stage, surgical findings, recurrence risk, or symptoms. It is not required for every patient.
Treatment for Advanced or Metastatic Disease
When gastric cancer has spread to distant organs or cannot be completely removed surgically, treatment generally focuses on controlling cancer growth, relieving symptoms, extending survival, and maintaining quality of life.
Systemic treatment may include chemotherapy, targeted medicines, immunotherapy, or combinations selected according to the patient’s tumor characteristics. In some situations, procedures may also be used to relieve complications such as obstruction or bleeding.
Benefits of Timely Treatment
The potential benefits of appropriate treatment include:
- Removing or controlling the primary tumor
- Reducing the risk of cancer progression
- Treating involved lymph nodes or distant disease when appropriate
- Relieving symptoms such as pain, bleeding, or obstruction
- Improving nutritional intake and quality of life
- Providing the best possible opportunity for long-term disease control
It is important to understand that no single treatment is suitable for every patient. The expected benefit depends strongly on cancer stage, biology, general health, and treatment response.
Recovery After Gastric Cancer Treatment
Recovery varies according to the treatment performed. Patients undergoing endoscopic treatment may recover relatively quickly, while recovery after gastrectomy generally takes longer.
After stomach surgery, dietary changes are often necessary. Patients may initially need smaller, more frequent meals and gradual dietary progression under medical and nutritional guidance.
Follow-up can include clinical examinations, blood tests, imaging, nutritional assessment, and additional investigations when indicated. Patients receiving chemotherapy, targeted therapy, or immunotherapy also require monitoring for treatment-related effects.
For Gastric Cancer Treatment in Delhi, choosing a specialist who can coordinate diagnosis, surgery, oncology care, and follow-up can help ensure that treatment decisions remain focused on the individual patient’s needs.
