Sniffing out cancer: new breath test aims to catch lung cancer early

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Age 21-85 * Single, monolateral nodule of at least 50% solid composition visible on chest CT scan (with or without contrast) suspicious for lung cancer. * MSK radiologist report or read suggestive (i.e. at least 50% certainty) of suspected primary lung cancer (in accordance with the level of certainty criteria set forth by MSKCC Radiology) o Patients with biopsy-proven early stage, primary lung cancer that meets staging requirements, do not need to also have a radiology report meeting inclusion criteria * Negative test for COVID-19 performed locally or at MSK, done as part of standard of care testing (i.e. only when required by specific institutional policy) prior to biopsy or surgical procedure * Eligible for fine-needle aspiration biopsy, robotic bronchoscopy, and/or surgical resection for diagnosis (i.e., does not have comorbidities precluding these). * Documented, signed, and dated informed consent, obtained before any procedures, for the proposed research study o Patient must agree to undergo fine-needle aspiration biopsy, robotic bronchoscopy, and/or surgical resection for diagnosis prior to e-nose collectionNote: Biopsy-proven patients that meet eligible staging criteria who are not further surgical candidates will be collected prior to next step in standard of care treatment * Patients with biopsy-proven clinical stage I lung cancer are eligible if the biopsy is done within 6 weeks of the consent date Exclusion Criteria: * Age \<21 and \>85 years at first outpatient visit. * Multiple ipsilateral or bilateral nodules reported on chest CT scan and/or concurrent as suspicious for lung cancer (note: nodules deemed indeterminate, inflammatory, etc. will not exclude a patient from participating in this study) semisolid GGOs. * Lung nodule of interest is less than 50% solid in composition * Per MSK radiologist report or read, the lung nodule of interest is "less likely" or "unlikely" (i.e. less than 50% certainty) to be neoplastic (in accordance with the level of certainty criteria set forth by MSKCC Radiology) * Any previous history of lung cancer * History of any non-lung cancer(s) that is currently being treated (note: prior history of completely treated non-lung cancer from any time will be eligible) * Metastatic lung cancer disease seen on chest CT or PET scan at hilar/mediastinal nodes or contralateral lung or extrathoracic sites. * Previous medical history of a lung biopsy/surgical procedure for cancer diagnosis (note: patients who underwent a lung biopsy over three years ago that showed negative for lung cancer and patients who underwent a lung biopsy confirming stage I lung cancer within the past 6 weeks will be eligible)
