Hereditary Diffuse Gastric Cancer Treatment in Delhi: A Guide for Families with Genetic Risk

Hereditary Diffuse Gastric Cancer (HDGC) is a rare but serious inherited cancer syndrome that significantly increases a person’s lifetime risk of developing stomach cancer. Unlike common gastric cancers, HDGC is linked to a genetic mutation, most commonly the CDH1 gene mutation and often goes undetected until the disease has advanced. Because of this silent progression, early awareness, genetic testing and expert clinical evaluation become essential.

For individuals and families with a gastric cancer genetic risk, understanding HDGC can be lifesaving. This article explains the causes, symptoms, hereditary risk, diagnosis and diffuse gastric cancer treatment options, along with why consulting the best GI cancer surgeon in Delhi, Dr. Neeraj Goel, a GI cancer specialist, is essential for safe and effective care.

What Is Hereditary Diffuse Gastric Cancer (HDGC)?

HDGC is a hereditary stomach cancer syndrome caused primarily by a CDH1 gene mutation. This mutation disrupts the function of a tumor-suppressor gene responsible for regulating cell growth. As a result, cancer cells multiply undetected within the stomach’s lining.

Why HDGC Often Goes Undiagnosed?

HDGC causes the stomach lining to thicken and harden rather than forming a traditional tumor. Early symptoms are minimal or absent, which makes diagnosis difficult. By the time symptoms appear, the cancer has often spread deeper into the stomach wall or nearby organs.

What Are the Symptoms of HDGC?

Common symptoms of HDGC include:

• Persistent stomach discomfort
• Bloating and nausea
• Unexplained weight loss
• Loss of appetite
• Fatigue
• Vomiting blood or blood in stools
• Difficulty swallowing
• Jaundice

What Causes Hereditary Diffuse Gastric Cancer Syndrome (HDGC)?

HDGC occurs due to a genetic mutation, most commonly in the CDH1 tumor-suppressor gene. This faulty gene is inherited from a biological parent and disrupts normal cell growth, increasing the risk of cancer. This is why early genetic testing, counseling and monitoring are strongly recommended.

Does Inheriting the Mutation Always Lead to Cancer?

No. In HDGC, you inherit one faulty gene, but the second gene copy still works. Cancer develops only if a second (somatic) mutation occurs later in life, disabling the remaining healthy gene.

Who Should Consider Genetic Testing for HDGC?

Testing may be recommended if:

• One or more family members have been diagnosed with diffuse gastric cancer.
• A close relative carries a known CDH1 gene mutation.
• There is a pattern of stomach cancer hereditary cases in your family.

Identifying the mutation early helps in planning proactive Hereditary Diffuse Gastric Cancer treatment in Delhi.

How HDGC Is Diagnosed?

Diagnosis of HDGC usually involves:

• Genetic testing: A simple blood test identifies the CDH1 gene mutation and assesses hereditary cancer risk.
• Upper endoscopy: It examines the stomach lining, though early HDGC is often difficult to detect.
• Biopsies: Multiple tissue samples from different stomach areas help detect hidden cancer clusters.

Because HDGC is difficult to spot in early stages, it is essential to be evaluated by a stomach cancer specialist in Delhi with extensive experience.

What are the Different Diffuse Gastric Cancer Treatment Options in Delhi?

Total Gastrectomy (Stomach Removal Surgery)

Total gastrectomy is often advised even before cancer develops because HDGC can spread silently and remain undetected. After surgery, the esophagus is joined to the small intestine, and patients can live normally with dietary adjustments and regular follow-ups.

Chemotherapy and Radiation

Used when cancer has already formed or spread.

Regular Surveillance

For those not ready for surgery, frequent endoscopies and biopsies are essential but may still miss early cancer.

Genetic Counseling and Family Planning

Families with HDGC may consider IVF with embryo screening to prevent passing on the CDH1 gene mutation.

Can Hereditary Diffuse Gastric Cancer Be Prevented?

While HDGC is inherited, careful management can reduce the severity and improve survival:

• Undergo genetic testing early
• Monitor for symptoms
• Schedule regular endoscopies
• Avoid smoking and excessive alcohol
• Treat H. pylori infections promptly
• Consult experienced specialists for gastric cancer treatment in Delhi
