A total of 19 consecutive patients with primary cancer recruited between March and July 2014 were submitted to preoperative MDCT staging according to a standard protocol. All diagnostic procedures were performed by dedicated radiologists who were unaware of the final pathological results. Subsequently, 16 patients underwent surgical treatment and 15 were finally included in the study. The primary tumor was detected at CT in all 15 cases. CT results for T staging were in agreement with pathological findings in 12 of 15 cases, with overall accuracy of 80%. Stage-specific sensibility was high for advanced stages (sensibility for T1, T3, and T4 resulted 60%, 85.7%, and 100%, respectively), while earlier stages showed higher specificity (specificity for T1, T3, and T4 resulted 100%, 75%, and 91.7%, respectively). Overall N staging accuracy was 86.7%, with 13 of 15 patients correctly staged. Stage-specific sensibility was 75% for N0 and 100% for N3, while specificity was 100% for N0 and lower for advanced stages. Accuracy for peritoneal involvement was 100%. Our findings show a good performance of the diagnostic protocol performed with MDCT tested in this study.展开更多

The purpose of this study was to prospectively analyze all post-gastrectomy complications in patients with gastric adenocarcinoma according to the severity grade using Clavien-Dindo system, in order to identify risk factors for postoperative complications and their prognostic significance on survival. Methods: This study is based on data from 90 consecutive patients who underwent gastrectomy for gastric neoplasia between January 2010 and February 2014 at the same unit. 15 patients were excluded (benign tumors, GISTs, missing data). Complications were categorized according to the Clavien-Dindo classification (uncomplicated patients vs patients classified ≥Grade I). The following risk factors were studied: age, BMI, sex, operation method, extent of resection, duration of surgery, transfusions, TNM staging, and lymph node ratio. Multivariate logistic regression was used to evaluate the association between risk factors and presence of complications. To assess the effect on overall survival, after selection of covariates using backward elimination, the Cox proportional hazard model was applied. Results: Among these patients, 49 (65.3%) developed complications, stratified as follows: Grade I, 6 (8%);Grade II, 24 (32%);Grade III, 6 (8%);Grade IV, 13 (17.3%). The laparoscopic technique (OR = 0.050;95% CI = 0.005 - 0.550, p = 0.0143) and no transfusions (OR = 0.219;95% CI = 0.058 - 0.827, p = 0.0251) were found to reduce the incidence of postoperative complications in the multivariate analysis. With regard to the survival analysis, lymph node ratio, malnutrition, extended resection and presence of complications were significant predictors of reduced survival in the multivariate analysis. Conclusions: Some variables can predict the risk of postoperative complications, the occurrence of which is a predictor of reduced probability of survival. In this respect it’s essential to reduce complications.展开更多

Both pathogenesis and risk factors of recurrence remain unclear. We describe a case report of a 49-year-old male who underwent subtotal gastric resection D2A for angular gastric cancer. Histological examination revealed gastric adenocarcinoma with low grade of differentiation and colloid areas, intramucosal, and absence of neoplastic proliferation in the surgical margins, in omental stroma and in the six examined lymph nodes (pT1, pN0). 11 years later, the same patient underwent D2 total gastrectomy for gastric cancer in the remnant stomach. New histological examination revealed again gastric adenocarcinoma, intramucosal, medium degree of differentiation, no documentable neoplastic proliferation within the limits of surgical resection, in the thirty-three examined lymph nodes and in the omentum (pT1, pN0).展开更多
