About this study

Official title: The Diagnostic Power of VOCs Compared With CTCs for Cancer

Early diagnosis of malignant tumors is pivotal for improving their prognoses. Circulating tumor cells (CTC) in peripheral blood and Volatile organic compounds (VOCs) in exhaled breath are newly developed diagnosis method. Due to the low percentage of CTCs in peripheral blood of cancer patients and the surface structure of lymphocytes (especially megakaryocytes) is often confused with tumor cells, CTC has a high false positive and negative rate. In recent years, the detection of volatile organic compounds (VOCs) in exhaled breath as a simple and noninvasive method has shown broad application prospects in the diagnosis of various diseases. A series of studies of VOCs diagnosing solid tumors the investigators had conducted in the past decade show that VOCs can not only distinguish different types of tumors, but also can make a distinction between different stages. This study was to compare CTC and VOCs with clinical samples. Predictive models will be built employing discriminant factor analysis (DFA) pattern recognition method. Sensitivity and specificity will be determined using leave-one-out cross-validation or an independent blind test set.

Read the detailed description

200 patients with definitive diagnoses will be enrolled and the alveolar exhaled breath samples and peripheral venous blood will be collected. Two blood samples and two breath samples will be collected from each patient. One blood sample will be send to CTC tests for a blind test and the other will be used for headspace VOCs analyses. One breath sample was used for analysis with the Nano-sensors array, and the other was used for gas chromatography coupled with mass spectrometry (GC-MS) analysis. The VOCs samples were collected using sorbent tubes at a total flow through sorption trap of 200ml/min, then will be send to Israel Institute of Technology for further test.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Discrimination between Malignant and Benign Gastric/Breast Lesions and normal group with each diagnostic method (Na-nose/GC-MS/CTC)

    Exhaled breath samples and peripheral venous blood collected will be used to build predictive models employing discriminant factor analysis (DFA) and thereafter examine the sensitivity and specificity of model identification.

    Measured: From June 15,2019 to June 1,2020

Secondary outcomes (1)
  1. Comprehensive diagnostic model of VOCs and CTCs

    Organize predictive models of VOCs/CTCs and establish Comprehensive Diagnostic Model.

    Measured: From June 1,2020 to Dec 31,2020
