Abstract
Background:
The identification of prognostic factors of gastric cancer (GC) has allowed
to predict the evolution of patients.
Aim:
Assess the reliability of the lymphoparietal index in the prediction of
long-term survival in GC treated with curative intent.
Method:
Prospective study of the Universidad de Chile Clinical Hospital, between May
2004 and May 2012. Included all gastric cancer surgeries with curative
intent. Exclusion criteria were: gastrectomies due to benign lesions, stage
4 cancers, R1 resections, palliative procedures, complete
esophagogastrectomies and emergency surgeries.
Results:
A total of 284 patients were included; of the sample 65.4% were male,mean age
of 64.5 years,75% were advanced cancers, 72.5% required a total gastrectomy,
30 lymph nodes harvest. Surgical morbidity and mortality were 17.2% and
1.7%. 5-year survival was 56.9%. The N+/T index could predict long-term
survival in all de subgrups (p<0.0001), although had a reliable
prediction in early GC (p=0.005), advanced GC (p<0.0001), signet ring
cell GC (p<0.0001), proximal GC (p<0.0001) and distal GC
(p<0.0001). The ROC curves N+/T index, LNR and T classification presented
areas below the curve of 0.789, 0.786 and 0,790 respectively, without a
significant statistical difference (p=0.96).
Conclusion:
The N+/T index is a reliable quotient in the prognostic evaluation of gastric
adenocarcinoma patients who have been resected with curative intent.
