Purpose: Lung cancer screening saves lives, but implementation is challenging. We evaluated two approaches to early lung cancer detection-low-dose computed tomography screening (LDCT) and program-based management of incidentally detected lung nodules.

Methods: A prospective observational study enrolled patients in the early detection programs.

Background: Responsible for 25% of all US cancer deaths, lung cancer presents complex care-delivery challenges. Adoption of the highly recommended multidisciplinary care model suffers from a dearth of good quality evidence. Leading up to a prospective comparative-effectiveness study of multidisciplinary serial care, we studied the implementation of a rigorously benchmarked multidisciplinary lung cancer clinic.

Surgery is the most important curative treatment modality for patients with early-stage non-small cell lung cancer (NSCLC). We examined the pattern of surgical resection for NSCLC in a high incidence and mortality region of the United States over a 10-year period (2004-2013) in the context of a regional surgical quality improvement initiative. We abstracted patient-level data on all resections at 11 hospitals in 4 contiguous Dartmouth Hospital Referral Regions in North Mississippi, East Arkansas, and West Tennessee.

Background: The National Comprehensive Cancer Network (NCCN) surgical resection guidelines for non-small cell lung cancer recommend anatomic resection, negative margins, examination of hilar/intrapulmonary lymph nodes, and examination of three or more mediastinal nodal stations. We examined the survival impact of these criteria.

Methods: A population-based observational study was done using patient-level data from all curative-intent, non-small cell lung cancer resections from 2004 to 2013 at 11 institutions in four contiguous Dartmouth Hospital referral regions in three US states.

The complexity of lung cancer care mandates interaction between clinicians with different skill sets and practice cultures in the routine delivery of care. Using team science principles and a case-based approach, we exemplify the need for the development of real care teams for patients with lung cancer to foster coordination among the multiple specialists and staff engaged in routine care delivery. Achieving coordinated lung cancer care is a high-priority public health challenge because of the volume of patients, lethality of disease, and well-described disparities in quality and outcomes of care.

Background: We examined the presurgical evaluation of suspected lung cancer patients in a community-based health care system to establish current benchmarks of care that will lay the groundwork for an evidence-based quality improvement project.

Methods: We retrospectively reviewed clinical records of all recipients of lung resection at two institutions, and classified all lung cancer relevant procedures into five "nodal points": lesion detection, diagnostic biopsy, radiologic staging, invasive staging, and treatment. We analyzed the frequency of passage through each nodal point, the time intervals between nodal points, and the use of staging modalities.
