About this study

The goal of this clinical trial is to develop a new cancer diagnostic and prognostic tool based on the dynamic and non-invasive detection of an exogenous volatile molecule, i.e., ethanol, from patients' samples. Patients' blood plasma will be analyzed with a mixture of volatile organic compound-based probes, each targeting a specific glycosidase. The presence of a given glycosidase in a blood sample would thus be revealed by the detection of an ethanol isotope in the gas phase. 3 groups of patients with localized cancer (breast, prostate, pancreas) will be enrolled, as well as 1 group of patient without any cancer (control group). For the patients, two 5ml plasma samples will be collected, one before and one after surgery for localized cancers. For healthy volunteers, only one 5ml plasma sample will be collected. The primary objective will be to compare the levels of glycosidases measured in the blood of patients followed for localized cancer and referred for first surgery compared to control patients without cancer.

Interventions

Biological: blood plasma sample — For each patient, 5ml blood sample will be needed before the surgery and another 5ml blood sample one month after the surgery.
Biological: blood sampling — 5ml blood sample for control arm

Primary outcomes

To compare the levels of glycosidases measured in the blood samples of patients treated for a localized cancer (breast, lung or pancreatic cancer) compared to control patients without cancer. (before surgery and one month after surgery)
