RESUMO
Objective:To investigate the relationship between metabolic syndrome (MetS) and clinicopathological characteristics of patients with gastric cancer.Methods:The clinicopathological data of 245 patients with gastric cancer diagnosed by pathology in Xinzhou People's Hospital of Shanxi Province from January 2015 to December 2018 were retrospectively analyzed, and 462 non-tumor patients who underwent routine physical examination at Xinzhou People's Hospital of Shanxi Province during the same period were selected as control group. The occurrence of MetS and the correlation of MetS with clinicopathological characteristics and overall survival of patients with gastric cancer were analyzed.Results:The incidence rate of MetS in 245 patients with gastric cancer was 21.6% (53/245) and 13.6% (63/462) in the control group, and the difference between the two was statistically significant ( χ2 = 7.464, P = 0.008). Among patients with gastric cancer, the incidence of postoperative lung infection in the MetS group and non-MetS group was 17.0% (9/245) and 3.1% (6/462), respectively, and the difference was statistically significant ( χ2 = 13.874, P = 0.001); there was no significant difference in the tumor site and the incidence of incision infection, abdominal cavity infection, anastomotic leakage, gastric emptying disorder, and overall survival between the two groups (all P > 0.05). In patients with gastric cancer, MetS was associated with poor histological differentiation and late TNM stage ( χ2 = 4.242, P = 0.040; χ2 = 5.547, P = 0.027). Conclusions:The incidence of MetS in patients with gastric cancer is higher than that in the general population, and MetS-related abnormalities are more common in patients with low differentiated, undifferentiated and advanced gastric cancer. MetS may play a role in the occurrence and development of gastric cancer.
RESUMO
Objective To investigate the clinicopathological significance of periostin and MMP-2 in colorectal carcinoma.Methods Immunohistochemistry was used to detect the expression of periostin and MMP-2 in colorectal carcinoma,tubular adenoma,villous adenoma and normal colorectal tissue.The correlations between the expression of periostin and MMP-2 with clinicopathologic parameters were analyzed.Results In colorectal carcinoma,tubular adenoma,villous adenoma and normal colorectal tissue,the positive rates of periostin were 83.7 ％ (41/49),40.0 ％ (6/15),32.1％ (9/28),0 (0/15),respectively,while the positive rates of MMP-2 were 71.4 ％ (35/49),60.0 ％ (9/15),64.3 ％ (18/28),0(0/15),respectively.There were significant differences among the groups (x2 =41.252,P =0.000; x2 =24.811,P =0.000).The expression of periostin in colorectal carcinoma tissue were not correlated with sex (x2 =0.002,P =0.961),age (x2 =2.267,P =0.132),tumor sites (x2 =1.506,P =0.220),differentiation status (x2 =0.875,P =0.350) and lymphatic metastasis (x2 =3.315,P =0.069).The expression of MMP-2 in colorectal carcinoma were correlated with lymphatic metastasis (x2 =5.800,P =0.016),whereas not correlated with sex (x2 =0.562,P =0.453),age (x2 =0.138,P =0.711),tumor sites (x2 =0.408,P =0.532),differentiation degree (x2 =1.335,P =0.248).The expression of periostin and MMP-2 were positively correlated in colorectal carcinoma (r =0.332,P =0.020).Conclusion Periostin and MMP-2 are correlated closely with the development and progression of colorectal carcinoma.It might be helpful for evaluating the biological properties and prognosis of colorectal carcinoma,and it would be more accurate to use a combined analysis of the two indicators.
