Abstract:
Objective:To analyze the relationship between tumor deposits(TD) and clinicopathological features of locally advanced gastric cancer(LAGC) patients.
Methods:The clinicopathological characteristics of 300 LAGC patients undergoing radical gastrectomy in Renmin Hospital of Wuhan University from Jan 2014 to Jul 2017 were collected. The relationship between clinicopathological features and prognosis of LAGC patients and TD status in LAGC patients were analyzed retrospectively.
Results:TD were positive in 65(21.7%) patients. Univariate analysis showed that the depth of invasion, lymph node metastasis, pTNM stage, tumor size, vascular invasion, preoperative tumor markers were correlated with the status of TD(all P<0.05). Multivariate Logistic regression analysis showed that lymph node metastasis, pTNM stage, vascular invasion and depth of invasion were independent risk factors for positive TD (allP<0.05). Univariate analysis on prognosis of LAGC patients showed lesion location, degree of differentiation, lymph node metastasis, pTNM stage, tumor size, positive TD, number of TD and vascular invasion are associated with prognosis of LAGC (all P<0.05). Multivariate COX regression analysis showed that the number of TD >3 was an independent risk factor for the prognosis of LAGC patients(HR=2.242, 95% CI: 1.484-3.386, P=0.000). The median survival time of TD-positive LAGC was less than TD-negative group(χ2=91.077, P<0.001). The median survival time of TD number>3 group was significantly shorter than that in TD number<3 group and TD-negative group(χ2=192.969, P<0.001).
Conclusions:TD are closely related to tumor stage in LAGC patients. The status of TD is an independent risk factor for the prognosis of LAGC. Multiple TDs indicate poor prognosis of LAGC patients.
