Abstract

Aims: To describe the relationship between the level of lymph node metastasis and tumor invasion pT1-T2 of gastric cancer patients after subtotal gastrectomy. Patient and Methods: A cross-sectional descriptive study. Study subjects: Patients with distal gastric cancer with pathological diagnosis of pT1-T2 who underwent radical surgery at Quan Su’s General Surgery Department, K hospital from 08/2023 to 08/2024. Results: Among the 52 patients studied, including 33 males and 19 females, the average age was 60.54±8.74 (ranging from 42 to 80). Lymph node metastasis was detected in 21 (40.4%) patients, with 21 (40.4%) patients having D1 lymph node metastasis and 10 (19.2%) patients having D2 lymph node metastasis. Tumor morphology, invasion level, histopathological grade, lymphatic invasion and perineural invasion were related to lymph node metastasis with p<0.05. Stage 2 lymph node metastasis was related to tumor morphology, invasion level and lymphatic invasion, p<0.05 Conclusion: Lymph node metastasis in gastric cancer occurs in tiers. Factors related to lymph node metastasis include tumor morphology, invasion level, histological grade, lymphovascular invasion, and perineural invasion. Factors related to D2 lymph node metastasis include tumor morphology, invasion level, and lymphovascular invasion.
