Precise Early Detection of Lung Cancer and Blood Cell Circuit

1. Precise Early Detection of Lung
Cancer and Blood Cell Circuit
Oleg Kshivets, MD, PhD Surgery Department, Roshal Hospital, Roshal, Moscow, Russia P2.11
Objective: Significance of blood cell circuit in terms of early detection of lung cancer (LC)
was investigated.
Methods: In trial (1987-2018) consecutive cases after surgery, monitored 115 LC patients
(LCP) (m=100, f=15; lobectomies=115) with pathologic stage IA (tumor size=1.86±0.30 cm;
squamous=51, adenocarcinoma=59, large cell=5; T1N0M0=115; G1=39, G2=42, G3=34, 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 LC from HD (n=235) significantly depended
on: leucocytes (abs, total), segmented neutrophils (%, abs, total), lymphocytes (%), monocytes
(abs, total) (P=0.012-0.000). Neural networks computing, genetic algorithm selection and
bootstrap simulation revealed relationships of early detection of LC and lymphocytes (rank=1),
stick neutrophils (rank=2), monocytes (3), segmented neutrophils (4), leucocytes (5),
eosinophils (6). Correct detection of early LCP was 100% by neural networks computing
(error=0.000; area under ROC curve=1.0).
Conclusion: Early detection of LC from HD significantly depended on blood cell circuit.
