Current Controversies in Cardiothoracic Imaging: Overdiagnosis at Lung Cancer Screening-Not So Bad After All-Counterpoint.

Initially introduced into the medical literature in research publications from "Special Project #1" of the Council for Tobacco Research, the concept of overdiagnosed lung cancer (OD LC) has consistently served to misinform and confuse the medical community, contributing to interminable delays in implementation of population lung cancer screening. Estimates of overdiagnosis vary enormously (9.5% to 75%).

Non-Small Cell Lung Cancer, Version 6.2015.

These NCCN Guidelines Insights focus on recent updates to the 2015 NCCN Guidelines for Non-Small Cell Lung Cancer (NSCLC). Appropriate targeted therapy is very effective in patients with advanced NSCLC who have specific genetic alterations. Therefore, it is important to test tumor tissue from patients with advanced NSCLC to determine whether they have genetic alterations that make them candidates for specific targeted therapies.

Survival following lung resection in immunocompromised patients with pulmonary invasive fungal infection.

Objectives: Pulmonary invasive fungal infections (IFIs) are associated with high mortality in patients being treated for haematological malignancy. There is limited understanding of the role for surgical lung resection and outcomes in this patient population.

Methods: This is a retrospective cohort of 50 immunocompromised patients who underwent lung resection for IFI.

Natural history of typical pulmonary carcinoid tumors: a comparison of nonsurgical and surgical treatment.

Background: The natural history of typical pulmonary carcinoid tumors has not been described and has important implications for counseling elderly patients or patients with high operative-risk about surgical resection.

Methods: Data from the Surveillance, Epidemiology, and End Results Program were used to identify 4,111 patients with biopsy specimen-proven lymph node-negative typical carcinoid tumor of the lung between 1988 and 2010; 306 had no resection, 929 underwent sublobar resection, and 2,876 underwent lobectomy. Overall survival and disease-specific survival (DSS) were analyzed using Kaplan-Meier plots.

Non-small cell lung cancer, version 1.2015.

This selection from the NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Non-Small Cell Lung Cancer (NSCLC) focuses on the principles of radiation therapy (RT), which include the following: (1) general principles for early-stage, locally advanced, and advanced/metastatic NSCLC; (2) target volumes, prescription doses, and normal tissue dose constraints for early-stage, locally advanced, and advanced/palliative RT; and (3) RT simulation, planning, and delivery. Treatment recommendations should be made by a multidisciplinary team, including board-certified radiation oncologists who perform lung cancer RT as a prominent part of their practice.

National lung screening trial limitations and public health policy.

The completion of the National Lung Screening Trial (NLST), a randomized controlled trial (RCT) of lung cancer screening (LCS), in 2010 provided powerful RCT evidence of the efficacy and safety of computed tomography-based screening; nevertheless, the study had important limitations. Failure to understand these limitations has had substantial adverse effects. Misinterpretation or misrepresentation of the results has led to underestimation of benefits and overestimation of adverse effects.

Minimizing over-diagnosis in lung cancer screening.

Overestimation of the frequency and impact of over-diagnosis bias in lung cancer screening has contributed to long delays in implementation of lung cancer screening programs. Literature review reveals little evidence of substantial numbers of over-diagnosed non-lethal lung cancer. There is now strong evidence that lung cancers that would not cause symptoms or kill during normal anticipated survival are uncommon and mostly limited to in situ adenocarcinomas, identifiable as CT non-solid nodules.

Non-small cell lung cancer, version 2.2013.

These NCCN Guidelines Insights focus on the diagnostic evaluation of suspected lung cancer. This topic was the subject of a major update in the 2013 NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Non-Small Cell Lung Cancer. The NCCN Guidelines Insights focus on the major updates in the NCCN Guidelines and discuss the new updates in greater detail.

Thymomas and thymic carcinomas: Clinical Practice Guidelines in Oncology.

Masses in the anterior mediastinum can be neoplasms (eg, thymomas, thymic carcinomas, or lung metastases) or non-neoplastic conditions (eg, intrathoracic goiter). Thymomas are the most common primary tumor in the anterior mediastinum, although they are rare. Thymic carcinomas are very rare.

Longitudinal changes in function, symptom burden, and quality of life in patients with early-stage lung cancer.

Background: Emerging evidence supports the integration of palliative care concurrently with disease-focused care in patients with serious illnesses, such as lung cancer. This paper describes how longitudinal changes in physical function, symptom burden, and QOL of patients with early-stage non-small cell lung cancer (NSCLC) informed the development of an interdisciplinary, tailored palliative care intervention.

Methods: Patients with early stage (I-IIIB) NSCLC were accrued into the usual care phase (Phase 1) of an NCI-funded Program Project Grant.

Non-small cell lung cancer.

Most patients with non-small cell lung cancer (NSCLC) are diagnosed with advanced cancer. These guidelines only include information about stage IV NSCLC. Patients with widespread metastatic disease (stage IV) are candidates for systemic therapy, clinical trials, and/or palliative treatment.
