It has been suggested that gastric cancer has a worse prognosis in young patients, but the data are controversial. The aim of this study was to compare the 5-year survivals after gastrectomy for gastric cancer in two groups of patients (those < or = 45 years of age and those (> 45 years) and to determine some of the prognostic factors. The 5-year survival was significantly better for patients < or = 45 years of age. Survival was also better for young patients with a curative resection and also for those with lymph node metastases. However, survival was not significantly different for the two groups when the resection was not curative and when the lymph nodes were not involved. Survival was no different for the two groups when compared at each stage, although a multivariate analysis showed that age > 45 years, moderate or poor degree of differentiation of the tumor, advanced tumors, the presence of lymph node involvement, and a noncurative resection were independent negative prognostic factors. Long-term survival after gastrectomy for gastric cancer depends on the stage of the disease; the age of the patient is not a decisive factor.

In this preliminary report, with 52% of advanced tumor, the 3-year overall and stage-by-stage survival was comparable for laparoscopic and open curative gastrectomy.

The Eleveld allometric PK model proved to be superior to all other tested models using TBW. All models, however, showed a trend to underestimate propofol concentrations. The use of adjusted body weight instead of TBW with the traditional Schnider and Marsh models markedly improved their performance achieving the lowest predictive errors of all tested models. Our results suggest no relevant effect of obesity on both the time profile of BIS response and the propofol concentration-BIS relationship.

This study demonstrated transfer of advanced laparoscopic skills acquired through a simulated training program in novice surgical residents to the OR.
