Association of neutrophil-lymphocyte ratio with survival in peripheral early-stage non-small cell lung cancer after stereotactic body radiation therapy.

Background: The role of neutrophil-lymphocyte ratio (NLR) as a predictor for survival in single fraction SBRT-treated non-small cell lung cancer (NSCLC) patients remains unclear. We performed an observational cohort study to determine the role of pretreatment NLR in predicting survival of early-stage NSCLC patients after single fraction SBRT.

Methods: A single-institution database of peripheral early-stage NSCLC patients treated with SBRT from February 2007 to May 2022 was queried.

Quality of Life After Stereotactic Body Radiation Therapy or Surgery for Early-Stage NSCLC: A Systematic Review.

Quality of life (QOL) is a key consideration for patients with early-stage NSCLC choosing between treatment options. Currently, it is not well established whether stereotactic body radiation therapy (SBRT) or surgery offers superior QOL in early-stage NSCLC. The objective of this systematic review is to summarize the prospective literature on QOL in patients with early-stage NSCLC after treatment with SBRT or surgery.

Massive hemoptysis resulting from a fistula between the bronchus intermedius and pulmonary artery: a novel clinical presentation.

This is a case of a woman with massive hemoptysis, associated with a pulmonary artery pseudoaneurysm, and a fistula between the right pulmonary artery and bronchus intermedius. Bronchoscopic evaluation revealed an endobronchial mass in the right bronchus intermedius, suspicious for a tumor. Upon biopsy of the mass, massive bleeding occurred.

A pilot study of stereotactic body radiation therapy (SBRT) after surgery for stage III non-small cell lung cancer.

Background: Standard therapy for stage III non-small cell lung cancer with chemotherapy and conventional radiation has suboptimal outcomes. We hypothesized that a combination of surgery followed by stereotactic body radiation therapy (SBRT) would be a safe alternative.

Methods: Patients with stage IIIA (multistation N2) or IIIB non-small cell lung cancer were enrolled from March 2013 to December 2015.

Clinically occult interstitial fibrosis in smokers: classification and significance of a surprisingly common finding in lobectomy specimens.

This study reports the presence of surprisingly frequent and often severe interstitial fibrosis in cigarette smokers with no clinical evidence of interstitial lung disease. Twenty-three lobectomy specimens excised for neoplasms, including 20 from smokers, were extensively sampled, and examined semi-quantitatively for interstitial fibrosis, fibroblast foci, peribronchiolar metaplasia, honey-comb change, emphysema, and respiratory bronchiolitis. Interstitial fibrosis involving greater than 25% of slides was identified in 12 of 20 smokers (60%), but in none of the three never-smokers.
