[Prognosis analysis of surgical treatment for cancer of stomach fundus and cardia with invasion to body and tail of the pancreas].
OBJECTIVE
To investigate the prognostic factors of surgical treatment for the cancer of stomach fundus and cardia with invasion to body and tail of the pancreas.


METHODS
A total of 135 patients with cancer of stomach fundus and cardia invading body and tail of the pancreas undergone surgical treatment were enrolled in this study. Twenty of them underwent laparotomy, while 115 underwent gastrectomy with pancreaticosplenectomy, even combined with the resection of other organs for macroscopic invasion to adjacent organs during surgery. The 3-,5-year survival rates, morbidity of postoperative complications and mortality were followed up. The prognostic factors were evaluated by univariate and multivariate analyses.


RESULTS
The median survival time of the patients undergone laparotomy was 4.7 months, of patients treated by gastrectomy combined with pancreaticosplenectomy was 30.5 months,and the difference was significant (chi(2)=403.8, P<0.01). The cumulative 3- and 5-year survival rates of the patients treated by gastrectomy combined with pancreaticosplenectomy were 48.3% and 26.6% respectively. Univariate analysis revealed that significant differences in prognosis of 115 patients undergone combined resection were demonstrated for the following factors: maximal dimension of tumor, macroscopic type, extent of lymph node metastasis according to the Japanese classification, No.10 or No.11 lymph node metastasis,curability and number of invaded organs.And histological depth of invasion, extent of lymph node metastasis according to the Japanese classification, number of invaded organs and curability were significant prognostic factors, examined as variables by multivariate analysis (Cox's proportional hazard model, forward stepwise selection LR method). The postoperative complication rate and mortality of 135 patients were 20.0% and 3.5% respectively.


CONCLUSIONS
For cancer located in stomach fundus and cardia with limited invasion to distal pancreas, gastrectomy combined with pancreaticosplenectomy should be performed to improve long-term outcomes. Best long-term survival outcomes would be attained if there are no lymph node metastases, or no incurable factors, or no other organ invasions.
