Indeterminate pulmonary nodules and prior malignancy: survival and recurrence after surgery in newly diagnosed stage I non-small cell lung cancer.

Background: Surgical excision biopsy remains the only reliable option in most cases of indeterminate pulmonary nodules, particularly in cancer survivors for whom surgery provides local control of pulmonary metastasis and the best chance of cure for early-stage lung cancer. Nevertheless, unnecessary surgeries remain a concern and the prognosis of newly diagnosed lung cancer might be influenced by the history of previous malignancy. We aimed to analyze the outcomes of resected indeterminate pulmonary nodules in patients with and without previous malignancy, and the impact of prior cancer history on survival and recurrence in stage I non-small cell lung cancer (NSCLC) patients.

Clinical Profile and Determinants of Mortality in Patients with Interstitial Lung Disease Admitted for COVID-19.

Background: Concern has risen about the effects of COVID-19 in interstitial lung disease (ILD) patients. The aim of our study was to determine clinical characteristics and prognostic factors of ILD patients admitted for COVID-19.

Methods: Ancillary analysis of an international, multicenter COVID-19 registry (HOPE: Health Outcome Predictive Evaluation) was performed.
