Breath Testing for Breast and Colon Cancer Diagnosis- NaNose Study

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

The concept of breath testing for various diseases has been around since ancient greece. It has been hypothesized that cancer is generating a unique pattern of compounds in patients' breath. This study is trying to characterize a novel system, based on nanoparticles technology, for cancer diagnosis through breath samples.

    Sensitivity and specificity of NaNose system in diagnosing cancer

Biospecimen Retention:   Samples Without DNA
Breath samples

Estimated Enrollment: 560
Study Start Date: February 2011
Estimated Study Completion Date: December 2011
Estimated Primary Completion Date: October 2011 (Final data collection date for primary outcome measure)
Breast cancer
Women diagnosed with breast cancer by a positive biopsy test after mammography.
Breast control
Women with negative biopsy result done due to a suspicious mammography exam.
Colon cancer
Men and women diagnosed with colon cancer by a positive colonoscopy and biopsy.
Colon control
Men and women with negative colonoscopy and biopsy tested due to complaints indicating the possibility of colon cancer.

Detailed Description:

Cancer is accompanied by increased oxidative stress and induction of polymorphic cytochrome P- 450 mixed oxidase enzymes (CYP). Both processes affect the abundance of volatile organic compounds (VOCs) in the breath because oxidative stress causes lipid peroxidation of polyunsaturated fatty acids in membranes, producing alkanes and methylalkanes which are catabolized by CYP.

In the Technion labs, a new system for breath samples diagnosis, is being developed. The system is based on Nanoparticles technology.

The current study will try to identify colon and breast cancer patients through their breath samples and discriminate them from healthy individuals.

Men and women coming for colonoscopy or breast biopsy will be recruited for the study. Breath samples will be taken from all volunteers before the medical test. Subjects with positive cancer results by biopsy will be the test groups for both diseases, all others will be the control.

The research goal is to test the NaNose system ability to discriminate between healthy and sick.


Ages Eligible for Study:   50 Years to 90 Years   (Adult, Senior)
