Western body mass indices need not compromise outcomes after modified D2 gastrectomy for carcinoma.

BACKGROUND: To determine the role of body mass index (BMI) in a Western population on outcomes after modified D2 gastrectomy (preserving pancreas and spleen where possible) for gastric cancer. METHODS: Eighty-four consecutive patients undergoing an R0 modified D2 gastrectomy for gastric cancer were studied prospectively. Male patients with a BMI of greater than 24.7 kgm(-2) and female patients with a BMI of greater than 22.6 kgm(-2) were classified as overweight and compared with control patients with BMIs below these reference values. RESULTS: Thirty-eight of the patients (45%) were classified as overweight. The median BMI of the overweight patients was 27.0 kgm(-2) (range, 22.7-34.7 kgm(-2); 27 males) compared with 21.2 kgm(-2) (range, 15.2-24.7 kgm(-2), 31 males) for control patients. Operative morbidity and mortality were 26% and 7.9% in overweight patients compared with 22% and 6.5% in control patients (morbidity, chi(2) = 0.240; df = 1; P = 0.624; mortality, chi(2) = 0.059; df = 1; P = 0.808). Cumulative survival at 5 years was 52% for overweight patients compared with 55% for control patients (chi(2) = 0.15; df = 1; P = 0.7002). In a multivariate analysis, the number of lymph node metastases (hazard ratio, 1.441; 95% confidence interval [CI], 1.159-1.723; P = 0.009) and splenectomy (hazard ratio, 12.111; 95% CI, 9.645-14.577; P = 0.043) were independently associated with the duration of survival. CONCLUSION: High BMIs were not associated with increased operative risk, and longterm outcomes were similar in the two groups after modified D2 gastrectomy.

D2 or not D2? The gastrectomy question.

BACKGROUND: The best reported long-term survival following surgery for gastric cancer is from centers performing radical D2 gastrectomy. Yet comparative studies from European centers report higher rates of postoperative complications following D2 gastrectomy than after the less radical D1 gastrectomy, without any benefit in survival. We aimed to compare the outcome after modified D2 gastrectomy (preserving spleen and pancreas where possible), performed by specialist surgeons, with that after conventional D1 gastrectomy performed by general surgeons for gastric cancer in a large United Kingdom cancer unit. METHODS: Two groups of patients were studied: a historical control group of 245 consecutive patients with gastric cancer, of whom 50 underwent a potentially curative D1 resection (median age, 69 years; 35 males) was compared with 200 consecutive patients, 72 of whom underwent a potentially curative D2 resection (median age, 71 years; 47 males). RESULTS: Among the 122 patients judged to have curable cancers, patients who underwent a D2 gastrectomy had lower operative mortality (8.3% vs 12%; chi(2) = 0.48; P = 0.50) and experienced fewer complications (28% vs 36%; chi(2) = 0.93; P = 0.35) than patients who underwent a D1 gastrectomy. Cumulative survival at 5 years was 56% after D2 resections, compared with 11% after D1 resections ( P < 0.00001). In a multivariate analysis, only the stage of disease (stage I, hazard ratio [HR], 0.068; P = 0.0001; stage II, HR, 0.165; P = 0.001; stage III, HR, 0.428; P = 0.053) and the level of lymphadenectomy (HR, 0.383; P = 0.00001) were independently associated with the duration of survival. CONCLUSION: Modified D2 gastrectomy without pancreatico-splenectomy, performed by specialist surgeons, can improve survival after R0 resections without increasing operative morbidity and mortality, when compared with D1 gastrectomy performed by general surgeons.
