title: The survival benefit of resection in patients with advanced stomach cancer: the Norwegian multicenter experience. Norwegian Stomach Cancer Trial.
abstract: Five hundred three of 1,165 patients with stomach cancer included in a national multicenter study received noncurative treatment. This study elucidates whether a palliative resection offered any survival advantage compared to nonresectional treatment. One hundred eighty-two (36%) of 503 patients had gastric resection (including total gastrectomy in 64 patients), 70 (14%) had a bypass procedure, and an exploratory laparotomy was carried out in 156 (31%). Seventy-eight patients (16%) were not subjected to surgery. Resection carried the same postoperative mortality rate as a nonresectional procedure (13% versus 12%). Univariate survival analysis demonstrated that median survival and 1- and 2-year survival rates were significantly higher in resected patients; however, as basic patient characteristics (age, stage, etc.) differed between the 2 main treatment groups, survival and factors affecting survival were analyzed using the Cox proportional hazards model. Given similar age and preoperative weight loss, resection doubled median survival both for stage III disease (9 versus 4.5 mo) and for stage IV disease (6 versus 3 mo) compared to nonresection or no operation. In conclusion, resection seems justified in patients with advanced stomach cancer since a survival benefit is documented.
