Abstract:
OBJECTIVETo investigate whether AJCC staging system(2010 edition) for gastric cancer has influence on the adoption of adjuvant chemotherapy.
METHODSThis was a cohort study and the data were collected from patients who underwent radical surgery and received adjuvant chemotherapy from January 2004 to December 2009. There were 48 patients with stage II( disease and 95 patients with stage III( disease according to TNM staging(2010 edition). Doublets were defined as 5-fluorouracil or capecitabine plus cisplatin or oxaliplatin, while triplets had epirubicin added. Ninety-six patients received doublet chemotherapy and 47 received triplet. All the patients were followed-up in the outpatient clinic until death or the censor time of May 2011.
RESULTSThe median follow-up time was 48 months in this cohort of 143 patients. The two groups had similar disease-free survival(DFS)(median, 23 months vs. 30 months, P>0.05). The median overall survival was 48 months in both groups. Subgroup analysis by TNM staging(2010 edition) showed that the median DFS of patients with stage III( gastric cancer was 15 months in the doublet group, significantly shorter than that of patients in the triplet group (18 months, P<0.05). However, the difference in overall survival was not statistically significant between the two groups. Patients with stage II( disease had comparable DFS and OS between the two groups(all P>0.05).
CONCLUSIONSTriplets regimens (epirubicin, platins and fluorouracil) show benefit on disease-free survival for the stage III( gastric cancer patients staged by TNM staging 2010 edition.
