The purpose of this research study is to test a new process for diagnosing lung cancer by examining changes to your DNA that can be detected from a blood test. The information we learn by doing this study could potentially help people in the future. Participants in this study will have blood samples collected, have their medical records reviewed by study personnel and fill out questionnaires at different time points during the study. Blood sample collection will occur during normal routine clinic visits. Participation in this study will last approximately 5 years.
This clinical testing research study outlines the validation process for an epigenetic assay targeting host peripheral blood cell and the associated host DNA methylation signatures designed to diagnose lung cancer. The overall protocol process will involve three distinct stages representing three patient cohorts with up to 250 subjects per cohort across 5 populations of patients. Cohort one will act as signature development phase; cohort two will act as signature finalization phase; and cohort three will act as a validation cohort phase. Each cohort will include the following patient populations with up to 50 patients per population: 1. Lung cancer; No chemotherapy. Surgical resection or stereotactic body radiation therapy (SBRT) only 2. Lung cancer; With chemotherapy. All stages including remission 3. At risk group (Lung cancer screening population) 4. Control group with mixed comorbid disease EXCLUDING tobacco use of greater than 10 pack years (PY) or chronic obstructive pulmonary disease (COPD) 5. Healthy controls with no comorbid disease
Study Type
OBSERVATIONAL
Enrollment
750
Up to 15 ml of blood will be collected from each patient at various time points throughout their 5 years of participation. DNA extraction, bisulfite conversion and analysis of epigenetic markers through PCR or next-generation sequencing will be performed. An epigenetic signature assay will then be identified.

RECRUITINGIdentification of tumor-associated host methylation signature
Genome-wide methylation profile of whole blood from lung cancer patients, pre-cancer patients, patients undergoing therapy, and control subjects.
Time frame: 5 years
Technology development
The investigators will develop array-based assays using whole-blood samples, focused on disease-specific methylation sites to provide early diagnosis, prognosis, and therapeutic efficacy prediction.
Time frame: 5 years
Technology validation
The investigators will validate identified blood-based circulating methylation signatures in patients with undiagnosed pulmonary nodules.
Time frame: 1 year
EORTC QLQ-C30 Questionnaire
The European Organization for Research and Treatment of Cancer core quality of life questionnaire, (EORTC QLQ-C30) is a cancer-specific quality of life instrument designed to assess health-related quality of life of cancer patients and is intended to be supplemented by disease-specific questionnaires, such as the lung cancer specific module, the EORTC QLQ-LC13. The EORTC QLQ-C30 incorporates nine multi-item scales including five functional scales (Physical, Role, Cognitive, Emotional and Social Functioning); three symptom scales (Fatigue, Pain and Nausea/Vomiting); and a Global Health Status/QoL scale. Six single item scales are also included (Dyspnea, Insomnia, Appetite Loss, Constipation, Diarrhea and Financial Difficulties). All of the scales and single-item measures range in score from 0 to 100. A higher score represents a higher level of symptom burden.
Time frame: 5 years
EORTC QLQ-LC13 Questionnaire
The European Organization for Research and Treatment of Cancer quality of life questionnaire module on Lung Cancer, EORTC QLQ-LC13, is a supplementary questionnaire meant to be used in conjunction with the full QLQ-C30. The QLQ-LC13 incorporates one multi-item scale to assess dyspnea, and a series of single items assessing pain, coughing, sore mouth, dysphagia, peripheral neuropathy, alopecia, and hemoptysis. All of the scales and single-item measures range in score from 0 to 100. A higher score represents a higher level of symptom burden.
Time frame: 5 years
SF-36v2 Questionnaire
The short-form of 36 questions (SF-36v2) is a multipurpose, 36-item survey that measures eight domains of health: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. It yields scale scores for each of these eight health domains, and two summary measures of physical and mental health. Higher scores indicate better health status.
