We performed a retrospective cohort study of patients with
Stage IB–IV (M0) gastric adenocarcinoma
who underwent resection
from 1991 to 2009
using the linked
SEER–Medicare database
Only 19.1% of patients received post
‐
operative
chemoradiation therapy (CRT), and
1.9% received
peri
‐
operative chemotherapy
; most patients underwent
surgery alone (60.9%)
The proportion of patients treated with postoperative
CRT increased significantly after trial publication as did the
‐
proportion of patients treated with peri operative
chemotherapy
There are a number of
hypotheses that might explain
the undertreatment of gastric cancer patients despite high
quality evidence supporting its use:
timeliness of information dissemination
economic impact of treatment
availability of resources and multidisciplinary expertise
