ABSTRACT
BACKGROUND:
In gastric adenocarcinoma, the disparity in lymph node involvement between different age groups has not been thoroughly investigated. The objective of our study was to compare age-associated differences in adequate lymph node harvest and nodal involvement in gastric adenocarcinoma patients.METHODS:
We analyzed data extracted from the Surveillance, Epidemiology and End Results database on 13,165 patients diagnosed with stage I-III gastric adenocarcinoma between 2004 and 2011. All patients underwent surgical resection. Statistical comparisons between various age groups were done using the chi-square test and Cox regression.RESULTS:
Among 13,165 gastrectomy patients, proportion of patients that had >15 lymph nodes examined decreases significantly with increasing age (P < 0.0001). When adequately staged, older patients had a significantly lower proportion of node-positive tumors (P < 0.0001). Adequate nodal staging was also associated with improved 5-y disease-specific survival across all age groups.CONCLUSIONS:
In gastric adenocarcinoma, older patients are less likely to be adequately staged. However, when adequately staged, they are less likely to have node-positive tumors. Adherence to national guidelines, regardless of age, is associated with improved survival outcomes and may alter multimodality management of gastric cancer in the elderly.Palavras-chave
