ABSTRACT The aim of this study was to investigate possible associations between (i) comorbid disease and (ii) perioperative risk factors and morbidity following radical surgery for gastric cancer.
Consecutive patients (759) undergoing radical gastrectomy and D2 level lymph node dissection for gastric cancer were included. Clinical data concerning patient characteristics, operative methods, and complications were collected prospectively.
The morbidity rate for radical gastrectomy was 14.2% (108/759). The most significant comorbid risk factors for postoperative morbidity were heart disease [anticoagulant medication: OR = 1.5 (95% CI = 0.35-6.6, P = 0.53); history without medication: OR = 4.0 (95% CI = 1.1-14.6, P = 0.03); history with current medication: OR = 6.7 (95% CI = 1.5-29.9, P = 0.01)] and chronic liver disease [chronic hepatitis: OR = 2.4 (95% CI = 0.9-6.5, P = 0.07); liver cirrhosis class A: OR = 8.4 (95% CI = 2.8-25.3, P = 0.00); liver cirrhosis class B: OR = 9.38 (95% CI = 0.7-115.5, P = 0.08)]. The most significant perioperative risk factors for postoperative morbidity were high TNM stage and combined organ resection (P < 0.05), and there was no association between increased postoperative morbidity and well controlled hypertension, anticoagulant therapy, diabetes mellitus, pulmonary disease, tuberculosis, or thyroid disease (P > 0.05).
Patients with heart disease or chronic liver disease are at a higher risk of morbidity following radical surgery for gastric cancer.

    ABSTRACT: This study was designed to determine the surgical outcomes of gastric cancer in elderly patients. This information can help establish appropriate treatment for these patients. A total of 1,193 patients with gastric cancer who underwent gastrectomy between 1995 and 2010 were enrolled in this retrospective study. The clinicopathologic features of 104 elderly patients (aged ≥80 years) were compared with those of 1,089 nonelderly patients. (1) Tumors located in the lower-third of the stomach, differentiated cancer, and surgery with limited lymph node dissection were more common in elderly patients. However, there was no difference in the proportion of laparoscopic gastrectomy between elderly and nonelderly patients. (2) Although surgical complication rates were similar in the two groups, the operative mortality rate was higher in elderly patients (1.9 %) than in nonelderly patients (0.7 %). (3) Elderly patients had a significantly poorer overall survival rate, whereas the disease-specific survival rates of the two groups were similar. Limited lymph node dissection did not influence the disease-specific survival rate of elderly patients. (4) The median life expectancy of elderly gastric cancer survivors was 9.8 years in patients aged 80-84 years and 6.0 years in those ≥85 years. The patients with limited lymph node dissection had slightly better prognosis. The treatment results in elderly patients were comparable to those in nonelderly patients. These findings suggest that R0 resection with at least limited lymph node dissection according to Japanese guidelines should be considered, even for elderly patients.

    ABSTRACT: Abstract Background: Post-operative pulmonary complications (PPCs) negatively affect patients' quality of life and can be life-threatening. Predictors of PPCs have been evaluated in patients who underwent various operations, but few studies have specifically focused on gastrectomy. Methods: We retrospectively studied 1,053 patients with gastric adenocarcinoma who underwent radical gastrectomy with lymphadenectomy in our hospital between 1999 and 2011. Post-operative pulmonary complications were defined as conditions such as pneumonia, macroscopic atelectasis, pneumothorax, and acute respiratory distress syndrome that developed within 30 d after surgery. We evaluated the relations between PPCs and pre-operative or intra-operative factors and assessed risk factors for PPCs after gastrectomy. Result: A total of 49 (4.7%) patients had PPCs. On univariate analysis, PPCs were significantly associated with male gender (p=0.024), predicted vital capacity (VC) (p=0.020), a lower pre-operative serum albumin concentration (p=0.023), open surgery (p=0.007), total gastrectomy (p<0.001), combined resection of another organ (p=0.001), extended operating time (p<0.001), higher operative bleeding volume (p<0.001), intra-operative or post-operative blood transfusion (p=0.009), and pathologic tumor stage (p=0.003). On multivariable analysis, extended operating time (odds ratio [OR], 3.21, 95% confidence interval [CI] 1.46-7.07; p=0.004), total gastrectomy (OR, 2.65, 95% CI 1.25-5.59; p=0.011) and predicted VC (OR, 2.42, 95% CI 1.01-5.85; p=0.049) were independent risk factors. These three factors also were independent risk factors for post-operative pneumonia (total gastrectomy OR, 2.64, 95% CI 1.32-5.30; p=0.006); extended operating time OR, 2.54, 95% CI 1.24-5.19; p=0.011; and predicted VC OR, 2.41, 95% CI 1.01-5.75; p=0.048). Conclusion: Extended operating time, total gastrectomy, and predicted VC were independent predictors of PPCs, particularly pneumonia, in patients with gastric cancer who underwent gastrectomy. In patients with restrictive pulmonary dysfunction who are scheduled to undergo total gastrectomy, reduced lymphadenectomy or the avoidance of combined resection should be considered to shorten the operating time.
