Abstract
Purpose
Although local resection like endoscopic mucosal resection for early gastric cancer is accepted as a treatment option, one of the most important drawbacks of such an approach is the inability to predictlymph node metastasis. The aim of this study was to evaluate the serum soluble receptor alpha for interleukin-2 (IL-2Rα) level as a predictor of lymph node metastasis in the patients with early gastric cancer.
Methods
Assessment of pre-operative serum IL-2Rα levels was performed on 86 patients with early gastric cancer treated by gastrectomies combined with D2 lymph node resections and 20 healthy controls at Samsung Medical Center. Data on patient age and gender, tumor size, depth of invasion, histologic differentiation, and endoscopic findings were reviewed post-operatively. The submucosal lesions were divided into three layers (sm1, sm2, and sm3) in accordance with the depth of invasion.
Results
Lymph node metastasis was observed in 16 patients (18.6%). Statistically, the serum IL-2Rα level was an important predictive factor of lymph node metastasis in undifferentiated gastric cancer, and the cut-off point for the predictive value of serum IL-2Rα level was 200 U/mL.
Conclusion
The serum IL-2Rα level might be a good predictor of lymph node metastasis in undifferentiated early gastric cancer.
