Learn More about CyPath® Lung

CyPath® Lung is sold by Precision Pathology Laboratory Services , a bioAffinity Technologies company, as a Laboratory Developed Test (LDT).

CyPath® Lung is a non-invasive test that assists clinical decision-making in lung cancer patients whose low-dose computed tomography (LDCT) has demonstrated a suspicious finding.

The test reveals the lung micro-environment by automated analysis of sputum using flow cytometry to characterize cell populations indicative of cancer in the lung.

CyPath® FAQ

Early Detection of Lung Cancer Saves Lives

Screening is an important tool to find lung cancer at the earliest stages and increase survival. The current protocol for screening people at high risk for lung cancer uses low-dose computed tomography (LDCT) to identify nodules in the lungs. But LDCT has a low positive predictive value that can lead to unnecessary invasive procedures.

Physicians order CyPath® Lung for patients who receive a suspicious but indeterminant LDCT result. CyPath® Lung has the potential to dramatically increase overall diagnostic accuracy leading to increased survival, fewer unnecessary invasive procedures, and lower patient anxiety and medical costs.

At-Home Sample Collection

With the at-home sample collection kit, patients use a simple noninvasive assist device that breaks up mucus in the lung to cough up a sputum sample over three days and overnight it to the lab.

▶  Video Demonstration

Flow Cytometry

Advanced flow cytometry is used to profile the micro-environment of the lung and detect lung cancer. A specific porphyrin labels cells in a sample to indicate cancer is present in the lung.

▶  Video Demonstration

Automated Data Analysis

Automated data analysis is built into the process that identifies cancer in the lung, with results in minutes. Physicians receive test results within three days after the sample arrives at the lab.

Study Description

Results

Porphyrin-modified beads for use as compensation controls in flow cytometry (Bauta, et al, Journal of Visualized Experiments, 2023) TCPP-modified compensation beads for flow cytometry allow TCPP fluorescence in sputum samples to be distinguished from other fluorescent molecules
Automated flow cytometry test distinguishes cancer from non-cancer in sputum with high sensitivity and specificity (Lemieux et al, Respiratory Research, 2023) Test validation trial using bioAffinity’s automated flow cytometry platform (cancer N=28 / high risk N=122) results in 82% sensitivity and 88% specificity; CyPath Lung sensitivity is 92% and specificity is 87% for patients with nodules smaller than 2 cm
Quality-controlled sputum analysis by flow cytometry to analyze the lung environment (Bederka, et al, PLOS ONE, 2022) Research confirms that bioAffinity has developed and tested a novel flow cytometry assay including quality controls that analyzes sputum in a high-throughput manner for diagnosis of lung cancer and other lung diseases (N=140)
Quality-controlled sputum analysis by flow cytometry for lung cancer detection (Grayson, et al., Journal of Visualized Experiments, 2021) Demonstrating the method for sputum processing that can be applied to flow cytometry platforms to analyze the sample for the diagnosis of lung disease including lung cancer, COPD and asthma
Early detection of lung cancer with Meso-Tetra (4-Carboxypheyl) Porphyrin-Labeled Sputum (Patriquin, et al, Journal of Thoracic Oncology, 2015) Clinical trial of high-risk smokers and cancer patients used microscopy-based assay to identify TCPP-labeled cells in sputum (cancer N=26 / high risk N =102) that resulted in 81% accuracy; 77.9% sensitivity, 65.7% specificity
Internal validation study with microscopy-based assay TCPP labeling of sputum in lung cancer samples Researchers measured TCPP-labeled cells under a microscope (cancer N= 15 / healthy N=12) resulting in 100% sensitivity and 100% specificity
Blinded study to diagnose lung cancer by labeling sputum with TCPP under a microscope Study of uranium miners (cancer N=8 / healthy N=4) labeling sputum with TCPP resulted in 100% sensitivity and 100% specificity
Porphyrin’s localization and evaluation of cancer cell uptake of 4 different porphyrins TCPP porphyrin localizes more than other porphyrins in cancer cells; higher uptake of TCPP in cancer cells than normal cells
