Summary
Maximum tumor diameter (DMAX) is a significant prognostic factor in gastric cancer (GC). Larger DMAX values correlate with advanced tumor stage and poorer survival, aiding patient selection for neoadjuvant therapy.
Area of Science:
- Oncology
- Surgical Pathology
Context:
- Gastric cancer (GC) prognosis is often linked to tumor characteristics.
- Maximum tumor diameter (DMAX) is increasingly recognized as a potential prognostic indicator.
Purpose:
- To retrospectively evaluate the prognostic value of DMAX in gastric cancer.
- To assess DMAX's predictive role in determining tumor stage.
Summary:
- A study of 164 gastric cancer patients found DMAX significantly correlated with survival (p=0.0001).
- DMAX strongly predicted tumor stage (88.5% PPV), pT, pN, residual tumor, and grading.
- Patients with larger tumors (DMAX >40 mm) face increased risk of tumor advancement.
Impact:
- DMAX serves as a valuable parameter for predicting gastric cancer advancement.
- Results suggest DMAX can aid in selecting patients for neoadjuvant treatment protocols.
