Prospective evaluation of lung cancer screening eligibility criteria and lung cancer detection in the Yorkshire Lung Screening Trial.

Introduction: Low dose CT (LDCT) screening for lung cancer reduces lung cancer mortality, but there is a lack of international consensus regarding the optimal eligibility criteria for screening. The Yorkshire Lung Screening Trial (YLST) was designed to evaluate lung cancer screening (LCS) implementation and a primary objective was prospective evaluation of 3 pre-defined eligibility criteria.

Methods: Individuals who had ever smoked, aged 55-80yrs, who responded to written invitation, underwent telephone risk assessment and if eligible by at least one criteria (PLCO≥1.

Understanding ethnic inequalities in diagnostic intervals of cancer: a cohort study of patients presenting suspected cancer symptoms to general practitioners in England.

Background: UK Asian and black patients experience longer cancer diagnostic intervals - period between initial symptomatic presentation in primary care and cancer diagnosis.

Aim: To determine whether these differences are due to prolonged primary care intervals (period between first primary care presentation and secondary care referral), referral interval (period between referral and first secondary-care appointment) or secondary care interval (period between the first secondary care appointment and diagnosis).

Design And Setting: We conducted a cohort study of patients with seven common cancers (breast, lung, prostate, colorectal, oesophagogastric, myeloma, and ovarian), diagnosed after presenting symptoms in English primary care.

Clinical risk factors for pancreatic cancer: protocol for an umbrella review.

Introduction: Identifying cancer earlier can help save lives. An increasingly popular approach to diagnosing cancer earlier is in the development of risk prediction models to be applied to the electronic healthcare record of patients. Development of these models requires systematic and thorough identification of the risk factors that might increase an individual's propensity to develop the disease.

Biomarkers suitable for early detection of intrathoracic cancers in primary care: a systematic review.

Intrathoracic cancers, including lung cancer, mesothelioma, and thymoma, present diagnostic challenges in primary care. Biomarkers could resolve some challenges. We synthesized evidence on biomarkers performance for intrathoracic cancer detection in low-prevalence settings.
