1. Precise Early Detection of Gastric
Cancer and Blood Cell Circuit
Oleg Kshivets, MD, PhD Surgery Department, Roshal Hospital, Roshal, Moscow, Russia
Objective: Significance of blood cell circuit in terms of early detection of gastric cancer
(GC) was investigated.
Methods: In trial (1975-2020) consecutive cases after surgery, monitored 136 GC
patients (GCP) (m=90, f=46; distal gastrectomies=95, proximal gastrectomies=34, total
gastrectomies=7) with pathologic stage IA (tumor size=1.81±0.70 cm;
adenocarcinoma=136; T1N0M0=136; G1=67, G2=26, G3=43, 5-year survival=100%) and 120
healthy donors (HD) (m=69, f=51) were reviewed. Variables selected for study were input
levels of blood cell circuit, sex, age, TNMG. Differences between groups were evaluated
using discriminant analysis, clustering, nonlinear estimation, structural equation
modeling, Monte Carlo, bootstrap simulation and neural networks computing.
Results: It was revealed that early detection of GC from HD (n=256) significantly
depended on: leucocytes (abs, total), segmented neutrophils (%, abs, total), lymphocytes
(%), monocytes (%, abs, total), stick neutrophils (%, abs, total), eosinophils (%, abs, total)
(P=0.007-0.000). Neural networks computing, genetic algorithm selection and bootstrap
simulation revealed relationships of early detection of GC and lymphocytes (rank=1),
segmented neutrophils (rank=2), monocytes (3), stick neutrophils (4), leucocytes (5),
eosinophils (6). Correct detection of early GCP was 100% by neural networks computing
(error=0.000; area under ROC curve=1.0).
Conclusion: Early detection of GC from HD significantly depended on blood cell circuit.
