However, available evidence is based on a limited number of trials, and the outcomes in routine clinical practice and in unselected patients are scarcely reported.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>The study included a consecutive series of patients with resectable gastric cancer treated between 2001 and 2011 in Central Norway. Before 2007, patients with resectable gastric cancer did not receive perioperative chemotherapy. Since 2007, medically fit patients with resectable gastric cancer and aged 75 years or less have been offered this. Response rates were evaluated by CT, and tolerability was assessed by the frequency of hospital admission, need for dose reduction or treatment discontinuation. The two time intervals were compared on an intention-to-treat basis for patients aged no more than 75 years for any impact on resection rates, surgical morbidity, postoperative mortality and long-term survival.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>About two-thirds (259) of the 419 patients registered were aged 75 years or less at diagnosis. Ninety-five of 136 patients in the later interval were eligible for chemotherapy, of whom 90 actually received the specified regimen, and 78 (87 per cent) were able to complete the preoperative course. Only 40 (44 per cent) completed all scheduled preoperative and postoperative cycles. Thirty-eight (43 per cent) of 89 evaluable patients showed a definite response on CT. Chemotherapy had no impact on postoperative morbidity or mortality. The 5-year survival rate on an intention-to-treat basis was 40\u00b77 (95 per cent c.i. 30\u00b77 to 50\u00b77) per cent in the first interval, compared with 41\u00b77 (31\u00b75 to 51\u00b79) per cent after the introduction of perioperative chemotherapy (P = 0\u00b7765). After adjustment for other risk factors, based on comparisons of the two time intervals, there were no differences in oncological outcomes with the use of perioperative chemotherapy.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Perioperative chemotherapy was completed in less than half of the patients with resectable gastric cancer.
