Predictors of operative morbidity and mortality in gastric cancer surgery
ABSTRACT The aim of this study was to identify factors that predict morbidity and mortality in gastric cancer surgery.
Data on 719 consecutive patients who underwent operations for gastric cancer at Seoul National University Hospital between January and December 2002 were reviewed.
Overall morbidity and mortality rates were 17.4 per cent (125 patients) and 0.6 per cent (four patients) respectively, and the rates of surgical and non-surgical complications were 14.7 per cent (106 patients) and 3.3 per cent (24 patients). Morbidity rates were higher in patients aged over 50 years (odds ratio (OR) 1.04 (95 per cent confidence interval (c.i.) 1.02 to 1.06)), when the gastric tumour was resected with another organ (36 per cent for combined resection versus 15.4 per cent for gastrectomy only; OR 3.25 (95 per cent c.i. 1.76 to 6.03)) and when gastrojejunostomy was used for reconstruction after subtotal gastrectomy (17.0 per cent for Billroth II versus 9.5 per cent for Billroth I; OR 2.00 (95 per cent c.i. 1.05 to 3.79)). Only three patients (2.8 per cent) with a surgical complication underwent reoperation, two for adhesive obstruction and one for intra-abdominal bleeding.
Age, combined resection and Billroth II reconstruction after radical subtotal gastrectomy were independently associated with the development of complications after gastric cancer surgery.

- "The molecular mechanisms responsible for the development of gastric adenocarcinoma are not entirely known. For example, in the intestinal type one can mainly observe the amplification of mutations of c-erb B2, C-MET genes and E cycline, mutations K-RAS gene, non-activation of p53, p16, MGMT and MLH1 genes, while in the diffuse type it has been observed reduction or losing of cadherin functions, non-activating p53 gene and amplification of K-SAM, C-MET genes and E cicline     .

ABSTRACT: The early gastric cancer is an endoscopic notion in which gastric cancer is strictly placed to mucosis and submucosis without extensive manifestations. It is the form with favorable prognosis and better survival at 5 and 10 years. Our study tries to systematize the debut forms of early gastric cancer and their association with the lesions with malignisation risk. We also try to evaluate the incidence of endoscopic and histopathologic forms of early gastric cancer found in an internal medicine division. Our study included 435 patients with gastric cancer endoscopic and histologic diagnosed. Statistically, 64.36% were men and 35.64% were women, the mean age 48 +/- 7 years. The endoscopic forms of early gastric cancer were type I: protruded in 19 cases, type II: superficially in eight cases, type III: excavated in six cases. Early gastric cancer is diagnosed with difficulty, it represents in 7.58% of the gastric cancer, being most frequently asymptomatic. The endoscopic forms frequently found in early gastric cancer in the population were type I: protruded and type IIa: superficially elevated. The histopathological examination is compulsory at this form of gastric cancer, while in advanced gastric cancer endoscopy is often sufficient for diagnosis. Analysing the histopathological results of cases diagnosed with early gastric cancer we found: 22 cases with intestinal type and 11 cases diffuse type. Microscopically, 15 were intramucosal and 18 had submucosal invasion. I and IIa lesions were predominantly located at the antrum and are histologically differentiated adenocarcinoma. Differentiated carcinoma frequently produces an elevated lesion and the border is well demarcated. There are frequent opportunities to detect gastric cancer in the early phase and the patient can expect a complete cure by the surgical operation or endoscopical mucosal resection.Romanian journal of morphology and embryology = Revue roumaine de morphologie et embryologie 02/2007; 48(4):373-9. · 0.72 Impact Factor

ABSTRACT: The aim of this study was to evaluate the outcome for gastric cancer patients treated at a medium sized Norwegian hospital. The medical journals of all 356 patients with gastric cancer treated at Levanger Hospital from 1980 to 2004 were retrospectively analysed. Follow-up with regard to survival was complete. The Department of Surgery had treated 277 patients (78%). The resection rate of patients admitted to the Department of Surgery was 56% (154/277), and the total resection rate was 43% (154/356). R0 resection was done in 97 patients (27%), R1 resection in 16 (4%), palliative R2 resection in 41 (12%), other palliative procedures in 59 (17%), and only palliative care was given for 143 (40%) patients. The 30-days postoperative mortality was 2.7% (3/113) after R0 and R1 resections, 4.9% (2/41) after R2 resections, and 24% (14/59) after other palliative procedures. After R0 resections, the estimated overall 5-year survival was 39% (95% C.I. 29-49). After R1 and R2 resections, none survived 5 years and the estimated overall 2-year survival was 12% (95% C.I. 0-27%) and 2% (95% C.I. 0-7%), respectively. Estimated overall 5-year survival was closely related to stage: 91% (95% C.I. 74-100) in stage 1A, 64% (95% C.I. 53-74) in stage 1B, 27% (95% C.I. 10-44) in stage II, 18% (95% C.I. 4-32) in stage IIIA, and none in stages IIIB and IV. Dysphagia, fatigue, weight loss, palpable tumour, ascites and anaemia were related to a bad prognosis. Dyspepsia, vomiting and hematemesis were not related to the prognosis. Symptoms duration > 6 months were related to a better prognosis than short duration of symptoms < 2 months. The results from this hospital are in accordance with previous reports from the Western world.Acta Oncologica 01/2007; 46(3):308-15. DOI:10.1080/02841860600996462 · 3.71 Impact Factor

ABSTRACT: Factors affecting mortality and morbidity in the abdominal operations Objective: Postoperative complications after abdominal operations is affected by many factors. The aim of this study was to identify factors that predict complications in abdominal operations. Material and Methods: 461 patients who had undergone abdominal operations at our clinic were prospectively researched. In this study age, gender, American Society of Anesthesiologists (ASA) grade of the patients and timing of surgery (elective or emergency), concomittant disease, type of operation, hospital stay and the mortality were examined. Results: The overall complication rate was 23%. Significantly higher complication occurred in male patients than female patients (30% vs 17.1%) (p
