Exanimation, Gastric Cancer, Lymph Node Metastases
Conditions
Brief summary
The aim of this study is intending to provide the optimal procedures of lymph node sorting for pathological examination after curative surgery for gastric cancer, which can discriminate the differences of the status of lymph node metastasis, pTNM classification and prognostic outcome of gastric cancer patients.
Interventions
In this study, intervention methods include two kinds of lymph node sorting for pathological examination in gastric cancer samples after curative surgery. One is the fine sorting lymph nodes, representing the lymph nodes should be sorted one by one from the tissues around the stomach, celiac axis, and the main brunches of celiac axis. The other is the group sorting lymph nodes, representing the lymph nodes should be simply sorted in the soft tissues around the stomach, celiac axis, and the main brunches of celiac axis.

Primary
| Measure | Time frame | Description |
|---|---|---|
| Migration of pN stage in gastric cancer patients | 60 months | According to the overall survival of all included patients, we will evaluate the optimal lymph node sorting method to obtain the accurately pathological stage of lymph node metastatic counts (pN stage) for prediction the prognosis of patients after curative surgery for gastric cancer. |
