Забор тканей и изучение естественного течения болезни у людей с немелкоклеточным раком легкого, мелкоклеточным раком легкого, внелегочным мелкоклеточным раком, легочными нейроэндокринными опухолями и эпителиальными опухолями тимуса

Background:

• Lung cancer is the leading cause of cancer-related death worldwide, accounting for more than one million deaths every year.
• Several genetic and epigenetic alterations are involved in initiation and progression of NSCLC. Some of these alterations are seen in normal and pre-neoplastic cells as well, suggesting a sequential development from normal epithelial cells to cancer, through a multistep process, usually coincident with cigarette smoking.
• This natural history protocol is an extension of our Molecular Profiling protocol to enable tissue collection for more in-depth proteomic and genomic analyses to understand tumor biology and treatment response.
• A cohort of patients enrolled in this natural history study is likely to enroll in the IRB approved protocol for end-of-life in-patient hospice and rapid autopsy following death (13-C-0131). Longitudinally collected tumor tissue from these patients, including from several metastatic sites at autopsy will be a unique resource to understand tumor evolution.
• There will be opportunity to embark upon a wide array of studies in the future with the longitudinally collected tissue samples tagged with clinical information from patients.

Objectives:

- To allow sample acquisition for use in the study of non-small cell lung cancer (NSCLC), Small cell lung cancer (SCLC), extrapulmonary small cell cancer (ESCC), pulmonary neuroendocrine tumors (PNET), and thymic epithelial tumors (TETs).

Eligibility:

• Patients with histologically or cytologically confirmed NSCLC, SCLC, ESCC, PNET, and TET.
• Patients consulted in the Clinical Center without a definitive diagnosis, but clinically considered likely to have a thoracic malignancy of the above histologies, pending further tissue acquisition and/or pathology review.
• Age greater than or equal to 18 years.

Design:

• This is a biospecimen collection and natural history protocol in which samples will be collected from patients with NSCLC, SCLC, ESCC, PNET, and TET.
• Eligible patients undergoing screening for or participating in NIH protocols or eligible patients treated elsewhere and referred from other oncologists will be referred for participation in this study.
• Upon providing informed consent, patients will undergo sample acquisition procedures, which may include a tumor biopsy, bone marrow biopsy or the collection of blood, urine or other body fluids.
• An accrual ceiling of 2000 subjects is planned.
