ObjectiveTo study and analyse the correlation between biologic behavior and clinical factors in gastric cancer.MethodsClinical and pathological study of carcinoma of stomach were retrospectively made in 1034 patients. ResultsIn this series,148 of 1034 patients (14.3%) were early gastric cancer.The frequency of lymph nodes metastasis was higher in proximal gastric cancer than distal (P<0.0001).Similar frequency can also be seen in the tumor of larger diameter (P<0.01),deeper invasion (P<0.0001) and poor differentiation (P=0.004).Some difference in ages and sex of patients may be found on the invasion (P=0.003),differentiation (P<0.0001),site (P<0.001) and frequency of lymph nodes metastasis of the tumor (P=0.01).In multifactorial multivariate linear regression analysis,the site of tumor (P=0.003),diameter of tumor (P<0.0001),depth of tumor infiltration (P<0.0001) and the cell differentiation showed significant association with lymph node metastasis,in which the female patient had more lymph node metastasis than male (P<0.001).Depth of tumor infiltration was the most important factor in lymph node metastasis.Numbers of lymph nodes resected were much more in total and distal gastrectomies than that in proximal gastrectomy (P<0.0001). ConclusionThe results of this study suggest that radical gastrectomy with lymphadenectomy is necessary even in all stages of gastric cancer.
Objective
To evaluate the effect of total gastrectomy (TG) and proximal gastrectomy (PG) for the treatment of advanced esophagogastric junction cancer.
Methods
Clinical data of 273 cases of advanced esophagogastric junction cancer who underwent TG and PG in our hospital from Jan. 2004 to Dec. 2010 were reviewed for retrospective analysis. Operation related indexes, 3-year cumulative survival rate, and 5-year cumulative survival rate were compared and evaluated.
Results
There was no significant difference between TG group and PG group in intraoperative blood loss, operation time, and hospital stay(P > 0.05), but the number of dissected lymph nodes in TG group was obviously more than those of PG group, and the difference was statistically significant(P=0.000). The postoperative complication rates were 10.3%(12/117)in TG group and 21.8%(34/156) in PG group respectively, which was lower in TG group(χ2=6.353, P < 0.05). The 3-year and 5-year cumulative survival rates of TG group were 58.9% and 34.2%, of PG group were 43.4% and 23.6% respectively, and the 3-year and 5-year cumulative survival rates were all lower in PG group(χ2=5.894, P < 0.05;χ2=5.582, P < 0.05). For patients in stage pT4, pN2, and TNMⅢ, whose tumor size were bigger than 3.0 cm, and patients who had accept chemotherapy, the 3-and 5-year cumulative survival rates of TG group were significantly higher than those of PG group(P < 0.05). However, for patients in stage pT2, pT3, pN0, pN1, pN3, TNMⅠ, TNMⅡ, TNMⅣ, whose tumor size were smaller than 3.0 cm, who had not accept chemotherapy, and patients of any pathological type, there was no statistically significant difference between the 2 groups in 3-year and 5-year cumulative survival rates(P > 0.05).
Conclusion
For the patients who suffered from advanced esophagogastric junction cancer, TG can improve long-term survival rate, and it can significantly reduce the incidence of postoperative complications and improve postoperative quality of life.
ObjectiveTo compare clinical outcome between single-incision laparoscopic subtotal gastrectomy (SILSG) versus laparoscopy-assisted subtotal gastrectomy (LASG) in treatment of benign gastric ulcer and duodenal ulcer.
MethodsClinical data of 37 patients with benign gastric ulcer or duodenal ulcer who underwent laparoscopic subtotal gastrectomy between Jan. 2008 and Feb. 2015 at Shengjing Hospital of China Medical University was collected retrospectively. Among them, 15 patients underwent SILSG and 22 patients underwent LASG. Demographic, intraoperative, and postoperative data was analyzed and compared between the 2 groups.
ResultsThe operative time of SILSG group was significantly longer than that of LASG group (P < 0.050). However, the postoperative hospital stay was significantly shorter (P < 0.050), and the total patient scar assesment scale (PSAS) score was significantly lower (P < 0.050) in the SILSG group than those of LASG group. There was no significant difference between the 2 groups with respect to other variables (P > 0.050), such as conversion rate, intraoperative blood loss, postoperative exhaust time, incidence of complication, and visual analog scale score of pain. All patients received postoperative follow up, and the period ranged from 6 months to 25 months, with a median of 11 months. During the follow up period, no one suffered from incision hernia and recurrence of ulcer.
ConclusionCompared with LASG, SILSG is a technically feasible procedure with better cosmesis and equivalent curability.
