Basis for Esophageal Cancer Diagnosis

1. Clinical presentation assessment
Assessment based on medical history and symptoms (e.g., progressive dysphagia) provides an initial diagnostic direction.

2. Endoscopic examination
Upper gastrointestinal endoscopy allows direct visualization of the lesion and biopsy, and is the primary method for definitive diagnosis.

3. Imaging examinations
CT and PET-CT are used to assess depth of invasion and metastatic disease, guiding staging and treatment planning.

4. Pathological biopsy
Histopathological results confirm tumor type and differentiation and form the foundation for treatment decision-making.

5. Endoscopic ultrasonography
Provides precise assessment of tumor infiltration depth and lymph node metastasis and is the most accurate modality for local staging.

6. Laboratory testing
Complete blood count, liver and renal function tests, and tumor markers are measured to assess the patient’s overall condition.

7. Barium swallow study
Dynamic evaluation of esophageal function and degree of stenosis helps assess surgical feasibility.

8. Molecular diagnostic techniques
Molecular biomarker testing guides individualized treatment selection and prognostic stratification.

Conclusion

Jinshazhou Hospital of Guangzhou University of Chinese Medicine emphasizes the importance of early diagnosis and precise subtyping of esophageal cancer. The public should remain vigilant for symptoms, undergo regular examinations, and seek timely medical attention to clarify the condition. Standardized diagnosis and treatment can improve cure rates and quality of survival.
