BACKGROUND Chest x-ray (CXR) is the first line investigation for lung cancer in many healthcare systems. Understanding of the consequences of false negative CXRs on time to diagnosis, stage and survival is limited. AIMS To determine the sensitivity of CXR for lung cancer and to compare stage at diagnosis, time to diagnosis and survival between those with CXR which detected, or did not detect, lung cancer. DESIGN & SETTING Retrospective observational study using routinely collected healthcare dat...

Background Chest X-ray (CXR) is the first-line investigation for lung cancer in many countries but previous research has suggested that the disease is not detected by CXR in approximately 20% of patients. The risk of lung cancer, with particular symptoms, following a negative CXR is not known. Aim To establish the sensitivity and specificity of CXR requested by patients who are symptomatic; determine the positive predictive values (PPVs) of each presenting symptom of lung cancer following a nega...

In the introduction section on line 7, the following sentence "A large epidemiological study of colorectal cancer patients with lung metastases found 3 and 5-year survival rates of 1.3% and 6.9%" should actually be "A large epidemiological study of colorectal cancer patients with lung metastases found 3 and 5-year survival rates of 11.3% and 6.9%".

INTRODUCTION To evaluate the long-term outcome of image-guided radiofrequency ablation (RFA) when treating histologically confirmed colorectal lung metastasis in terms of overall survival (OS), progression-free survival (PFS) and local tumour control (LTC). MATERIALS AND METHODS Retrospective single-centre study. Consecutive RFA treatments of histologically proven lung colorectal metastases between 01/01/2008 and 31/12/14. The primary outcome was patient survival (OS and PFS). Secondary outcomes...

Introduction/objectives The majority of patients are diagnosed with lung cancer following an abnormal chest X-ray (CXR) ordered in response to respiratory symptoms. However, CXR will miss some symptomatic lung cancers, and such patients may be expected to present with lung cancer in the months after a non-diagnostic CXR. Using information from a large dataset of patients presenting for self-request CXR (SR-CXR), we sought to determine outcomes from lung cancers diagnosed at different time interv...

Introduction/objectives The main route to diagnosis for lung cancer patients remains chest X-ray (CXR) performed in response to respiratory symptoms. The positive predictive value (PPV) of symptoms for lung cancer has not been studied in large prospective datasets. The Leeds self-request CXR (SR-CXR) service offers CXR for patients 50 years+who fulfil criteria from the NICE Lung Cancer Guideline (CG24). Symptoms and smoking status are collected from all patients in a standardised manner. Methods...

Introduction and objectives The route-to-diagnosis of lung cancer patients has been well studied, with those diagnosed following emergency presentation shown to have worse outcomes. Much less is known about patient outcomes according to the imaging that leads to their diagnosis, and the context in which this was ordered. We therefore sought to describe ‘Radiological Routes to Diagnosis’ (RRTD), and assess the frequency of these routes, and the outcomes of cancer patients according to these categ...
