Abstract:
142 Background: A prognostic model in advanced gastric cancer that integrates the Her2 status,histopathological classifications and other patient’s or treatment-dependent parameters is lacking. The aim is to identify clinicopathological factors for overall survival in a cohort of patients with advanced gastric cancer. Methods: 526 consecutive patients with advanced adenocarcinoma of the distal esophagus, gastroesophageal junction or stomach were analyzed. All patients were treated with poly-chemotherapy ( ≥ 2 drugs) at 19 Spanish and one Chilean centers between 2012 and 2015. Characteristics of patients, tumors, therapies and pathological factors, were analyzed by a Cox proportional hazards model. Results: The median overall survival was 10.3 months [95% confidence interval (CI), 9.5-11.1], and the time to progression was 6.7 months (95% CI, 6.1-7.2). Independent prognostic factors associated with overall survival were: distal non-diffuse histopathological subtype (hazard ratio, (HR) 0.73), Her2 positive 3+ (HR 0.54), Her2 positive 2+ with FISH + (HR 0.68), surgery of metastases (HR 0.34), Eastern Cooperative Group performance status (ECOG PS) 2 (HR 2.5), ECOG PS 3 (HR 7.37), and only distant lymph node metastases (HR 0.63) (Table 1). Conclusions: We have identified clinicopathological prognostic factors that could be important to stratify advanced gastric cancer, with potential implications in research and treatment.
