These initial results support the development of CT plus
IO combinations in locally advanced GC/GEJC and could

shed light on the identification of novel putative biomarkers. Further analyses are still ongoing.

Background: Surgery followed by aCT is one of the
standard of care for resectable GC, mostly in Asia.
Although meta-analyses reported a 6% absolute improvement in 5-year OS for fluoropyrimidine-based aCT, these
were mainly inflated by Asian studies. Western trials failed
to show a clear survival benefit for aCT, and the benefit of
oxaliplatin-containing regimen is even more controversial.
The aim of this retrospective analysis is to compare FuCT
vs OxCT and to assess the impact on survival of clinicopathologic features.
Method: 112 treated with FuCT were compared with 119
pts treated with OxCT between Jan-2009 to Jun 2019 at 2
Italian institutions. Kaplan-Meier curves and Cox regression method were used for survival analysis. Patients
undergoing FuCT or OxCT were matched 1:1 using the
propensity score matching (PSM) method, and a survival
analysis was conducted on matched patients.

Results: Clinical data of 231 nodes positive GC pts underwent aCT (112 treated with FuCT and 119 with OxCT) were
retrospectively collected. At multivariate analysis age, performance status (PS-ECOG), grading, LVI, positive resection
margin (R1), tumor location, pathological stage (III vs II), T
status independently correlated with DFS (p=0.001, 0.002,
0.006, <0.0001, <0.0001, <0.0001, 0.02). The median DFS
was 95.6 m (95% CI: 50.5-140.7) and 77.3 m (95% CI: 60.494.2) for FuCT and OxCT respectively (log-rank p0.78)
while mOS 120.4 m and 72.9 m (p=0.36), respectively. Seven
variables were unbalanced in the two groups. After PSM, the
indipendent variables significantly associated with survival
were PS-ECOG, LVI and pathological stage. Even after PSM,
no differences were observed in both mDFS and mOS
between the two groups (p=0.36 and p=0.67 respectively).
Conclusions: In this retrospective study, we demonstrated
that adding oxaliplatin to FuCT did not improve DFS or
OS in a western population of resected GC. Using PSM to
reduce treatment allocation bias and simulate randomization which is the main limitation of a retrospective study,
we have confirmed the prognostic value of known clinicopathological features and the crucial role of surgery in this
tumor. Prospective randomized studies, including molecular biomarkers, are guaranteed to better stratify the risk
points that could benefit from a more aggressive regimen
and those to which only FuCT could be offered.
