| Study Title | Serum phosphatidylethanolamine levels distinguish benign from malignant solitary pulmonary nodules and represent a potential diagnostic biomarker for lung cancer (part II) |
| Study Summary | Recent computed tomography (CT) screening trials showed that it is effective for early detection of lung cancer, but were plagued by high false positive rates. Additional blood biomarker tests designed to complement CT screening and reduce false positive rates are highly desirable. In the current study, we expand upon our initial experimental findings as part of the discovery phase by evaluating metabolites in serum from subjects with benign or malignant SPNs using a combined approach of gas chromatography time-of-flight mass spectrometry (GC-TOFMS) and hydrophilic liquid chromatography accurate mass quadrupole time-of-flight mass spectrometry (HILIC-qTOFMS). Furthermore, we evaluated serum collected pre-diagnosis and at-diagnosis of lung cancer in addition to samples obtained post-surgical intervention from subjects with malignant SPNs (post-diagnosis). We hypothesize that our systems biology approach to identify candidate metabolomics biomarkers will ultimately lead to improved early detection of lung cancer and can be used in as a companion blood test to LDCT screening. |

Collection:
| Collection ID: | CO000404 |
| Collection Summary: | Blood samples were collected from all patients enrolled in the protocol before diagnosis (>6 months prior to surgery, pre-diagnostic). Additional blood samples were collected from some of the lung cancer patients, at-diagnosis (at diagnosis) and post-treatment (after surgery). All but one patient had their “at-diagnosis” sample collected before surgery, usually within days prior to surgery, likely on their pre-operation visit. Surgery was usually performed within 1–3 months of diagnosis. Diagnosis was made by biopsy and/or surgery with all tissue diagnoses confirmed by pathology. |
