Gastric Cancer Diagnosis

Gastric cancer is a malignant tumor originating from the gastric mucosa. If not diagnosed and treated in the early stages, cancer cells may rapidly spread, leading to poor prognosis. Accurate diagnosis is crucial for developing an effective treatment plan. Clinical diagnosis typically relies on gastroscopy, combined with tissue biopsy and imaging techniques, to determine tumor characteristics and staging.

Diagnostic Basis

1. Gastroscopy
Gastroscopy is the gold standard for gastric cancer diagnosis, allowing direct observation of gastric lesions and evaluation of tumor size, morphology, and location. Combined with biopsy, it provides pathological samples to confirm cancer cell type and malignancy level, making it the key method for definitive diagnosis.

2. Pathological Biopsy
Tissue collected through gastroscopy is examined pathologically to determine cellular characteristics and differentiation levels of cancer, offering critical information for treatment planning. Biopsy results aid in classification and prognosis prediction.

3. Imaging Examinations
Imaging modalities such as CT, MRI, and endoscopic ultrasound are used to assess the depth of tumor invasion and detect lymph node or distant metastasis, supporting clinical staging. Positron emission tomography (PET-CT) is particularly valuable in identifying occult metastases.

4. Serum Tumor Marker Tests
Tumor markers related to gastric cancer, such as carcinoembryonic antigen (CEA) and carbohydrate antigen 19-9 (CA19-9), are not essential for diagnosis but may assist in disease evaluation and treatment monitoring.

5. Molecular Biology Tests
Some patients require genetic mutation and molecular marker testing to guide targeted and immunotherapy, enhancing the level of personalized treatment.

Conclusion

Experts at the United Life International Medical Center emphasize that gastric cancer diagnosis relies on the comprehensive application of various diagnostic methods, with early detection being crucial. Combining immune reconstruction cell therapy promotes personalized treatment and improved outcomes. Patients should actively cooperate with professional examinations to ensure timely diagnosis and treatment.
