Detection of Lung Cancer by Plasma Lipids

Completed
Conditions
Early-Stage Lung Cancer
Interventions
Diagnostic Test: Plasma lipids
Registration Number
NCT04287712
Lead Sponsor
Peking University People's Hospital
Brief Summary

There are no reliable blood-based tests currently available for early-stage lung cancer diagnosis. We try to establish a highly accurate method for detecting early-stage lung cancer by combining machine learning with untargeted and targeted metabolomics .

Detailed Description

All plasma lipids were first detected by untargeted metabolomics methods and 9 feature lipids of early-stage lung cancer were selected by support vector machine algorithm. Then, a targeted metabolomics method was developed to detect the 9 lipids quantitatively based on multiple reaction monitoring mode. Finally, a detection model was established based on the 9 lipids.

GroupInterventionDescription
Participants received surgeryPlasma lipidsPatients who underwent surgery at the Department of Thoracic Surgery of Peaking University People's Hospital, Jiangsu Cancer Hospital, and Beijing Haidian Hospital were enrolled with the following criteria: 1) pathologically confirmed lung cancer; 2) no history of other malignancies; 3) no anti-cancer treatment (chemotherapy, radiotherapy, targeted therapy, etc.) before surgery. Plasma samples were collected before surgery and plasma lipids were detected by mass spectrometry. Pathological diagnosis and clinical characteristics of enrolled participants were retrieved.
Primary Outcome Measures
NameTimeMethod
Plasma LipidsAll samples were detected together after participants recruitment and sample collection. All samples were detected within 18 months from sample collection.

A detection model based on 9 lipids were developed, including 3 lysophosphatidylcholines, 5 phosphatidylcholines, and a triglyceride. The 9 lipids were detected by targeted metabolomics by mass spectrometry.
