What Is Stomach Cancer?

Stomach cancer, also known as gastric cancer, is a complex disease. It originates in the lining of the stomach, specifically in the gastric mucosa and glandular tissue. This system of cells can develop abnormalities, leading to the formation of tumors.

Definition and Overview

The stomach’s inner layer, or mucosa, is where most stomach cancers begin. Over 90% of these cases are adenocarcinomas, which develop from glandular cells. These tumors can grow in two main patterns: intestinal and diffuse. Intestinal types often have a better prognosis, while diffuse subtypes are more aggressive.

Types of Stomach Cancer

Besides adenocarcinomas, there are rarer forms of gastric cancer. These include lymphomas, gastrointestinal stromal tumors (GISTs), and neuroendocrine tumors. Each type requires a unique treatment approach. For example, GISTs respond better to targeted therapies than traditional chemotherapy.

Metastasis occurs through pathways like the lymphatic system, bloodstream, or direct spread to nearby organs. Understanding these patterns helps in planning effective treatments. Early detection and accurate diagnosis are crucial for improving outcomes.

How Is Stomach Cancer Diagnosed?

Identifying stomach cancer early can significantly improve treatment outcomes. However, diagnosis often occurs at advanced stages, making early detection challenging. Recognizing alarm symptoms like hematemesis, dysphagia, and unintentional weight loss is crucial for timely intervention.

Early Detection Challenges

Many cases are diagnosed at Stage 3 or 4, when symptoms become more noticeable. Persistent issues such as abdominal pain or digestive discomfort should prompt immediate medical evaluation. Guidelines recommend referrals for patients with persistent alarm symptoms to ensure early diagnosis.

Diagnostic Methods

Several tools and techniques are used to confirm the presence of this condition. Endoscopy is a primary method, allowing doctors to visualize the stomach lining and take biopsies. Advanced imaging like CT and PET scans helps detect metastasis, with PET scans offering higher sensitivity for certain cases.

Endoscopic ultrasound (EUS) combines imaging modalities to assess tumor depth and lymph node involvement. EUS-guided fine-needle aspiration (EUS-FNA) is particularly useful for sampling submucosal lesions. Tumor markers like CEA and CA19-9 are monitored to track disease progression and treatment response.

Multidisciplinary tumor boards review complex cases to determine the best treatment approach. This collaborative process ensures personalized care and improved outcomes.
