Risk-Based lung cancer screening: A systematic review.

AI Article Synopsis

Article Abstract

Lung cancer remains the leading cause of cancer related deaths worldwide. Lung cancer screening using low-dose computed tomography (LDCT) has been shown to reduce lung cancer specific mortality. In 2013, the United States Preventive Services Task Force (USPSTF) recommended annual lung cancer screening with LDCT for smokers aged between 55 years to 80 years, with at least 30 pack-years of smoking exposure that currently smoke or who have quit smoking within 15 years. Risk-based lung cancer screening is an alternative approach that defines screening eligibility based on the personal risk of individuals. Selection of individuals for lung cancer screening based on their personal lung cancer risk has been shown to improve the sensitivity and specificity associated with the eligibility criteria of the screening program as compared to the 2013 USPSTF criteria. Numerous risk prediction models have been developed to estimate the lung cancer risk of individuals incorporating sociodemographic, smoking, and clinical risk factors associated with lung cancer, including age, smoking history, sex, race/ethnicity, personal and family history of cancer, and history of emphysema and chronic obstructive pulmonary disease (COPD), among others. Some risk prediction models include biomarker information, such as germline mutations or protein-based biomarkers as independent risk predictors, in addition to clinical, smoking, and sociodemographic risk factors. While, the majority of lung cancer risk prediction models are suitable for selecting high-risk individuals for lung cancer screening, some risk models have been developed to predict the probability of malignancy of screen-detected solidary pulmonary nodules or to optimize the screening frequency of eligible individuals by incorporating past screening findings. In this systematic review, we provide an overview of existing risk prediction models and their applications to lung cancer screening. We discuss potential strengths and limitations of lung cancer screening using risk prediction models and future research directions.

Mechanical ventilation (MV) remains a cornerstone of critical care; however, its prolonged application can exacerbate lung injury, leading to ventilator-induced lung injury (VILI). Although previous studies have implicated ferroptosis in the pathogenesis of VILI, the underlying mechanisms remain unclear. This study investigated the roles of ferritinophagy in ferroptosis subsequent to VILI.

Background: The therapeutic efficacy and prognosis of various tumors can be assessed using the systemic immune-inflammatory index (SII) and prognostic nutritional index (PNI). Despite their potential, no studies have investigated the prognostic value of the combined SII-PNI score for outcomes in patients with extensive small cell lung cancer (ES-SCLC) treated with chemotherapy and immune checkpoint inhibitors (ICIs).

Materials And Methods: Our study retrospectively examined 213 ES-SCLC patients treated with chemotherapy and ICIs across two institutions.

Background: Using primary airway epithelial cells (AEC) is essential to mimic more closely different types and stages of lung disease in humans while reducing or even replacing animal experiments. Access to lung tissue remains limited because these samples are generally obtained from patients who undergo lung transplantation for end-stage lung disease or thoracic surgery for (mostly) lung cancer. We investigated whether forceps or cryo biopsies are a viable alternative source of AEC compared to the conventional technique.

Statin use after cancer diagnosis and survival among patients with cancer.

Cancer Causes Control

December 2024

Division of Public Health Sciences, Fred Hutchinson Cancer Center, 1100 Fairview Ave N, M4-C308, Seattle, WA, 98019, USA.

Purpose: The association between statin use and cancer survival has been investigated in previous studies with conflicting findings. This study aimed to assess the association between statin use following cancer diagnosis and survival in six common cancers using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database.

Methods: Individuals aged ≥ 66 years diagnosed with prostate cancer, colorectal cancer, lung cancer, bladder cancer, pancreatic cancer, or non-Hodgkin lymphoma (NHL) from 2008 through 2017 were identified.

Lung cancer (LC) remains the primary cause of cancer-related mortality, largely due to late-stage diagnoses. Effective strategies for early detection are therefore of paramount importance. In recent years, machine learning (ML) has demonstrated considerable potential in healthcare by facilitating the detection of various diseases.
