Abstract:
Objective:To explore the prognosis of patients with T1b stage gallbladder carcinoma underwent different surgical procedure.
Methods:The clinicopathological data of 97 patients with T1b stage gallbladder carcinoma came from 8 clinical centers from January 2010 to December 2016 and 794 patients who were admitted to the SEER database of USA from January 1973 to December 2014 were analyzed.There were 891 patients including 254 males and 637 females (1.0∶2.5) with age of (69.5±12.0)years. There were 380 patients who were less than 70 years old, 511 patients who were more than 70 years old. And there were 213 patients with the diameter of tumor less than 20 mm, 270 patients with the diameter of tumor more than 20 mm, 408 patients were unclear. There were 196 patients with well differentiation, 407 patients with moderately differentiation, 173 patients with poorly differentiation, 8 patients with undifferentiated, 107 patients were unclear. In the 891 patients with T1b stage gallbladder carcinoma, there were 562 cases accepted the simple cholecystectomy, 231 cases with simple cholecystectomy plus lymphadenectomy, and 98 cases with radical cholecystectomy. The time of follow-up were until June 2017. χ2 test was used to analyze the enumeration data, rank-sum test was used to analyze the measurement data, the analyses of prognostic factors were used Cox proportional hazards model, the survival analysis was performed using Kaplan-Meier method.
Results:The results of Cox proportional hazards model indicated, age, differentiation, surgical procedure were the risk factors of prognostic(1.929(1.594-2.336), P<0.01; 1.842(1.404-2.416), P<0.01; 1.216(0.962-1.538), P<0.01). The results of Kaplan Meier test indicated, the overall survival of T1b stage gallbladder carcinoma were (85.5±3.8)months, the overall survival of patients with simple cholecystectomy were (71.3±4.4)months, the overall survival of patients with cholecystectomy plus lymphadenectomy were(87.6±5.8)months, and the overall survival of patients with radical cholecystectomy were(101.7±9.3)months. The overall survival of patients with cholecystectomy plus lymphadenectomy and radical cholecystectomy were more than simple cholecystectomy(P<0.05). There were 329 patients with Lymph nodes examined in and after operations(231 patients with cholecystectomy plus lymphadenectomy, 98 patients with radical cholecystectomy). There were 265 patients with negative lymph node metastasis, the overall survival were(98.3±4.2)months. There were 64 patients with positive lymph node metastasis, the overall survival were(75.5±3.1)months. The overall survival of 38 patients with cholecystectomy plus lymphadenectomy were(62.7±2.6) months, and 26 patients with radical cholecystectomy were (82.2±3.7)months. The overall survival of patients with radical cholecystectomy were more than cholecystectomy plus lymphadenectomy(P<0.05).
Conclusions:The T1b stage gallbladder carcinoma patients with cholecystectomy plus lymphadenectomy or radical cholecystectomy has improved the prognosis comparing with simple cholecystectomy, significantly. When lymph node metastasis occurs, radical cholecystectomy has improved the prognosis comparing with cholecystectomy plus lymphadenectomy.
