Edition Number： 1.0

Principal Investigator： Jingyu Deng and Han Liang
Research Institute： Cancer Hospital & Institute of Tianjin Medical University

Protocol:
Randomized included in the study
Fine sorting lymph nodes from samples 
for pathological examination
Group A（Fine sorting lymph nodes）
（n=138）
Group B（Regional sorting lymph nodes）
（n=138）
Undergo curative gastrectomy plus D2 lymphadenectomy
Regional sorting lymph nodes from 
samples for pathological examination
–
Gastric adenocarcinoma identified by histopathologic examination
–
Undergo potentially curative gastrectomy plus D2 lymphadenectomy (cTanyNanyM0)
–
Age between 18 and 70 years
–
KPS score >60
–
No neoadjuvant therapy
–
No seriously chronic diseases of important organs
–
No other malignancies
Differences of lymph node 
count for pathological 
examination between above 
mentioned two groups of 
patients according to each 
pTNM classification, pN 
stage and pT stage
Differences of overall 
survival between 
above mentioned two 
groups of patients 
according to each 
pTNM classification
Differences of 
recurrence between 
above mentioned 
two groups of 
patients according 
to each pN stage
Differences of overall 
survival and pN stage 
between above 
mentioned two groups 
of patients according to 
each pT stage
Elucidation the influences of lymph node metastatic migration in gastric 
adenocarcinoma patients underwent curative surgery by different lymph 
node sorting methods to evaluate the optimal method for pathological 
examination after surgery
