Gastric Cancer

Comprehensive Diagnostic & Therapeutic Reference Profile

Also known as: Stomach Cancer, Adenocarcinoma of the Stomach, Gastric Carcinoma.

📖
Section 1

Disease Overview

Gastric cancer is a malignant growth originating from the lining of the stomach. It is a heterogeneous disease, primarily categorized as adenocarcinoma, which arises from glandular cells. While global incidence is declining, it remains a leading cause of cancer-related mortality worldwide due to late-stage presentation.

Section 2

Medical Classification

Disease Category
Oncological Diseases
ICD Classification
C16.9 (Malignant neoplasm of stomach, unspecified)
🧬
Section 3

Etiology & Causes

Etiology involves the interplay of chronic inflammation and genetic mutations. Primary drivers include Helicobacter pylori infection, which induces chronic gastritis, and dietary factors such as high intake of salt-preserved foods, nitrates, and low fruit/vegetable intake. Genetic predisposition, such as E-cadherin (CDH1) mutations, plays a crucial role in hereditary diffuse gastric cancer.

⚙️
Section 4

Pathophysiology

Development typically follows the Correa cascade: chronic gastritis → atrophy → intestinal metaplasia → dysplasia → adenocarcinoma. It involves loss of tumor suppressor genes (e.g., p53) and activation of oncogenes. Tumors may spread via direct invasion, lymphatic metastasis, or hematogenous dissemination to the liver and peritoneum.

📊
Section 5

Epidemiology

Gastric cancer is more prevalent in East Asia, Eastern Europe, and South America. It is twice as common in males as in females, with a median age of diagnosis between 60 and 70 years.

⚠️
Section 6

Risk Factors

H. pylori* infection


  • Tobacco use and excessive alcohol consumption

  • Family history

  • Atrophic gastritis and pernicious anemia

  • Obesity and gastroesophageal reflux disease (GERD)

  • Previous gastric surgery

🤒
Section 8

Symptoms

A. Early Symptoms


  • Dyspepsia

  • Mild nausea

  • Loss of appetite B. Common Symptoms

  • Persistent abdominal pain

  • Early satiety

  • Unexplained weight loss C. Advanced Symptoms

  • Dysphagia

  • Vomiting (sometimes blood-stained)

  • Melena

  • Ascites and palpable abdominal mass D. Emergency Symptoms

  • Hematemesis

  • Severe gastric outlet obstruction

  • Perforation symptoms (acute rigid abdomen)

🩺
Section 9

Physical Examination

Inspection may reveal cachexia or supraclavicular lymphadenopathy (Virchow’s node). Palpation may reveal an epigastric mass or hepatomegaly. Auscultation is typically unremarkable unless an obstruction produces high-pitched tinkling bowel sounds.

🔍
Section 10

Diagnostic Evaluation

A. Clinical Assessment: History taking and physical exam.
B. Laboratory Testing: CBC for anemia, liver function tests.
C. Imaging Studies: CT scan (chest/abdomen/pelvis) for staging.
D. Functional Tests: Not applicable.
E. Biopsy Findings: Endoscopic biopsy showing histopathology (e.g., signet-ring cell).
F. Genetic Testing: HER2 expression levels, PD-L1 status, MSI testing.
G. Differential Diagnosis: Peptic ulcer disease, gastric lymphoma, GIST.

Section 11

Laboratory Tests

Complete Blood Count
Type: Blood Test
Purpose: Assess for anemia.
Expected Findings: Low hemoglobin/hematocrit.
Interpretation: Suggests chronic occult blood loss.

📷
Section 12

Imaging Studies

Endoscopic Ultrasound (EUS): Used for T-staging; high accuracy in determining depth of invasion.
CT/PET-CT: Used for distant metastasis assessment and overall staging.

🔀
Section 13

Differential Diagnosis

Peptic Ulcer Disease (usually non-malignant history), Gastric Lymphoma (different treatment protocol), Gastric Outlet Obstruction secondary to benign strictures.

💢
Section 14

Complications

Malnutrition, anemia, obstruction, metastasis, and cachexia.

💊
Section 15

Treatment Options

A. Lifestyle Modifications: Smoking cessation, diet high in antioxidants.
B. Preventive Measures: H. pylori eradication.
C. Medical Treatment: Chemotherapy (Fluoropyrimidines, Platinum-based agents), Targeted Therapy (Trastuzumab), Immunotherapy (Pembrolizumab).
D. Surgical Treatment: Gastrectomy (subtotal or total) with lymphadenectomy.
E. Interventional Procedures: Endoscopic Mucosal Resection (EMR) for early lesions.
F. Rehabilitation: Nutritional counseling.
G. Emergency Management: Stent placement for obstruction or surgery for perforation.

📉
Section 16

Prognosis

Prognosis is highly stage-dependent. 5-year survival for localized disease is ~70%, while metastatic disease remains under 10%.

🛡️
Section 17

Prevention

Screening programs (gastroscopy) in high-risk regions; H. pylori testing.

Section 19

Homeopathic Perspective

The following homeopathic remedies have been historically indicated for symptoms associated with Gastric Cancer. Selection should be based on individualized symptom totality and constitutional assessment.
