Lung cancer screening works better when individual risk factors are taken into account, study says

New research estimates that in a single year, some 5,000 lung cancer deaths might be averted if some former smokers who don ’t currently qualify for lung-cancer screening were to get a computed tomography scan capable of detecting malignancy.The U.S. Preventive Services Task Force, which lays down...

BackgroundThe study was conducted to evaluate the performance of a state ‐of‐the‐art commercial deep learning‐based computer‐aided diagnosis (DL‐CAD) system for detecting and characterizing pulmonary nodules.MethodsPulmonary nodules in 346 healthy subjects (male: female  = 221:125, mean age 51 years) from a lung cancer screening program conducted from March to November 2017 were screened using a DL‐CAD system and double reading independently, and their performance in nodule detection and characterization were evaluated. An expert panel combined the results of the DL‐CAD system and doubl...

Radiation oncologist Dr. Andrea McKee believes deaths from lung cancer — including those related to asbestos exposure — could be reduced significantly by increased utilization of early CT screening. McKee, chair of radiation oncology at Lahey Hospital and Medical Center in Burlington, Maine, has been a strong proponent of early screening for several years. “We could be saving tens of thousands of lives every year with this,” McKee told The Mesothelioma Center at “There is nothing else like it. The life-saving potential is the most important thing that has happened to cancer in my...

Accurately detecting and examining lung nodules early is key in diagnosing lung cancers and thus one of the best ways to prevent lung cancer deaths. Radiologists spend countless hours detecting small spherical...

Grand River Hospital in Waterloo, Ontario is introducing a portable multi-energy x-ray imager as an alternative to CT scan for lung cancer screening. The makers of the device claim it to be cost-effective and emit 50 times less radiation than a CT scan.The creators of the x-ray are KA Imaging, a Canada-based startup with a robust and innovative range of medical imaging products. Previously, they were awarded  $1 million Canadian dollarsfrom the Grand Challenges Canada fund to develop a LCD-based x-ray that uses less radiation and is cheaper to manufacture." With our single X-ray, you sort of walk up to the X-ray,...

CONCLUSIONS:: The model predicting patient survival following SABR in NSCLC may be useful in future studies by enabling prediction of survival-based outcomes using radiomics features in CT images. ADVANCES IN KNOWLEDGE:: Quantitative image features from NSCLC nodules on CT images have been found to significantly separate patient populations based on overall survival (p = 0.04). In the long term, a non-invasive method to estimate treatment outcomes in patients undergoing SABR would be valuable, especially since access to tissue specimens is often difficult in these cases.

Conclusion: Some comorbidities have a major adverse impact on survival. IPF management requires a comprehensive approach, which includes the identification and treatment of comorbid conditions. The protective effect of obesity we have examined elsewhere. The apparent protective effect of latent TB needs to be further explored.

Conclusion: An adequate interpretation of follow-up radiologic examinations is crucial not to miss a post-operative complication or even recurrenceDifferentiating recurrence from postsurgical changes could be challenging for radiologists; reviewing evolution of imaging patterns of previous exams may be helpful to distinguish them.

This study is managed by the departmental cancer screening agency (ADEMA80).All general practitioners, pulmonologists and radiologists from Somme were solicited by mail to participate in this study.218 general practitioners, 17 pneumologists and 28 radiologists accepted to participate in this study. 998 subjects were recruited in 20 months and 663 scans were performed representing a participation rate of 66%. Screening was negative in 608 cases (92%), positive in 42 (6.3%) and indeterminate in 13 (1.9%).17 cancers were detected. There were 10 adenocarcinomas,2 squamous cell carcinomas, 1 carcinoid tumor, 2 small cell carci...

Conclusions: CT reporting by dedicated thoracic radiologists shoud be encouraged where possible to ensure expertise is appropriately used to faciliate meaningful use of resources and avoid unnecessary burden on nodule/lung cancer services and patients.
