Introduction

Stomach cancer, also known as gastric cancer, raises many urgent and complex questions for patients and their families. To provide clarity, we have synthesized the viewpoints of leading gastroenterology and oncology experts. This Q&A addresses the most critical topics, from early warning signs and diagnosis to the advanced treatment options available at world-class medical centers.

What are the early warning signs of stomach cancer?

The earliest signs of stomach cancer are often vague and can be mistaken for other, less serious conditions. Many patients experience no symptoms in the initial stages. When symptoms do appear, they can include:

• Persistent indigestion and heartburn: Discomfort that does not resolve with standard treatments.

• Unexplained weight loss: Losing weight without changes in diet or exercise.

• Loss of appetite: Feeling full after eating only a small amount of food early satiety.

• Abdominal pain: A dull, persistent ache in the upper abdomen.

• Nausea and vomiting: Which may sometimes include blood.

• Bloating and frequent burping.

• Difficulty swallowing dysphagia.

• Black, tarry stools melena: Indicating bleeding in the upper gastrointestinal tract.

Because these symptoms overlap with common conditions like gastritis or peptic ulcers, it is crucial to consult a doctor if they are persistent or worsening.

How is stomach cancer definitively diagnosed?

A definitive diagnosis of stomach cancer requires a multi-step process to identify cancerous cells and determine the extent of the disease. The cornerstone of diagnosis is an upper GI endoscopy, also known as an esophagogastroduodenoscopy (EGD).

1. Upper GI Endoscopy with Biopsy: A flexible tube with a camera endoscope is passed down the throat to visualize the lining of the esophagus, stomach, and the first part of the small intestine. The physician looks for any abnormal areas. If suspicious tissue is found, a biopsy is performed, where small tissue samples are removed for microscopic examination by a pathologist. This is the only way to confirm the presence of cancer cells.

2. Endoscopic Ultrasound: If cancer is confirmed, an EUS may be performed. This specialized procedure uses an endoscope with an ultrasound probe at its tip. It provides detailed images of the stomach wall and nearby lymph nodes, helping doctors understand how deeply the cancer has penetrated and if it has spread locally. This is a critical step for TNM staging.

3. Imaging Tests: CT scans of the chest, abdomen, and pelvis are used to see if the cancer has spread to other organs metastasis, such as the liver or lungs. A PET scan may also be used to detect cancer spread throughout the body.

What are the primary treatment options for stomach cancer?

Treatment for stomach cancer is highly dependent on the stage of the disease, the tumor's location, and the patient's overall health. Treatment plans are typically multidisciplinary, combining several approaches.

• Surgery Gastrectomy: This is the primary treatment for cancers that have not spread extensively. The goal is to remove the part of the stomach containing the tumor, along with nearby lymph nodes. Depending on the cancer's location and size, this can be a subtotal gastrectomy part of the stomach removed or a total gastrectomy the entire stomach removed. Many top centers in South Korea specialize in minimally invasive laparoscopic or robotic-assisted gastrectomies, which can lead to faster recovery.

• Endoscopic Resection: For very early-stage cancers that are confined to the innermost layer of the stomach lining the mucosa, it is sometimes possible to remove the tumor using an endoscope. This avoids major surgery.

• Chemotherapy: Uses powerful drugs to kill cancer cells throughout the body. It can be used before surgery neoadjuvant to shrink a tumor, after surgery adjuvant to kill any remaining cancer cells, or as the main treatment for advanced or metastatic cancer.

• Radiation Therapy: Uses high-energy rays to target and destroy cancer cells. It is often used in combination with chemotherapy, either before or after surgery.

• Targeted Therapy: These newer drugs are designed to attack specific vulnerabilities in cancer cells. For example, some stomach cancers have too much of a protein called HER2. Drugs like trastuzumab Herceptin can target these cells.

• Immunotherapy: This treatment helps the body's own immune system recognize and fight cancer cells. It is primarily used for advanced stomach cancers.

What is the connection between H. pylori and stomach cancer?

Helicobacter pylori H. pylori infection is the single most important risk factor for stomach cancer. This bacterium can live in the lining of the stomach and, over many years, cause chronic inflammation gastritis.

This persistent inflammation can lead to pre-cancerous changes in the stomach lining, a condition known as atrophic gastritis and intestinal metaplasia. Over time, these changes can progress to dysplasia and then to gastric adenocarcinoma, the most common type of stomach cancer. The World Health Organization classifies H. pylori as a Group 1 carcinogen, meaning it is a definite cause of cancer in humans. Eradicating H. pylori with antibiotics significantly reduces the risk of developing stomach cancer.

How does stomach cancer staging work?

Staging is the process of determining the extent of the cancer. The most widely used system is the TNM system from the American Joint Committee on Cancer (AJCC).

• T (Tumor): Describes how deeply the primary tumor has grown into the stomach wall. A lower T number like T1 indicates a more superficial cancer, while a higher number like T4 means the tumor has grown through the stomach wall.

• N (Nodes): Indicates whether the cancer has spread to nearby lymph nodes. N0 means no lymph node spread, while N1, N2, or N3 indicate spread to an increasing number of lymph nodes.

• M (Metastasis): Describes whether the cancer has spread to distant parts of the body. M0 means there is no distant spread, while M1 indicates the cancer has metastasized to organs like the liver, lungs, or distant lymph nodes.

These factors are combined to determine the overall stage, from Stage 0 carcinoma in situ to Stage IV metastatic cancer. The stage is crucial for determining the prognosis and the best course of treatment.

What are the most critical takeaways for patients?

• Do not ignore persistent digestive symptoms. Early diagnosis dramatically improves outcomes. Consult a gastroenterologist if you have ongoing indigestion, unexplained weight loss, or abdominal pain.

• Diagnosis requires a biopsy. While imaging is important, only an endoscopic biopsy can confirm if an abnormality is cancerous.

• Treatment is highly personalized. The best treatment plan depends entirely on your specific cancer stage. A multidisciplinary team of surgeons, oncologists, and gastroenterologists should be involved.

• South Korea is a global leader in stomach cancer treatment. The country has one of the highest 5-year survival rates globally, partly due to a national screening program and expertise in advanced surgical and endoscopic techniques.

"For months, I was terrified by what I read online. Finally speaking with a specialist who walked me through the EGD and biopsy results, explaining every step and what it meant for me, was a turning point. The fear didn't vanish, but the confusion did, and that gave me the strength to face the treatment." – an anonymous patient, Australia.
