Ablation, radiotherapy boost lung cancer patients' survival
Patients with inoperable lung cancer treated with a combination of thermal ablation and radiotherapy were able to add two years to their survival times, according to Brown University Medical School researchers.
Dr. Damian Dupuy, an interventional radiologist at Brown, and colleagues enrolled 41 patients with inoperable stage I/II non-small cell lung cancer tumors who underwent thermal ablation and radiotherapy between 1998 and 2005. The investigators performed 37 radiofrequency and four microwave ablation procedures, followed within 90 days by either external-beam radiotherapy or brachytherapy in 27 and 14 patients, respectively (J Vasc Interv Radiol 2006;17[7]:1117-1124).
None of the patients were expected to live longer than one year, according to the panel of specialists who selected them for the study. The combination therapy, however, prolonged the patients' lives about two years beyond that point.
MRI-Based AI Radiomics Model Offers 'Robust' Prediction of Perineural Invasion in Prostate Cancer
July 26th 2024A model that combines MRI-based deep learning radiomics and clinical factors demonstrated an 84.8 percent ROC AUC and a 92.6 percent precision-recall AUC for predicting perineural invasion in prostate cancer cases.
Breast MRI Study Examines Common Factors with False Negatives and False Positives
July 24th 2024The absence of ipsilateral breast hypervascularity is three times more likely to be associated with false-negative findings on breast MRI and non-mass enhancement lesions have a 4.5-fold likelihood of being linked to false-positive results, according to new research.
Can Polyenergetic Reconstruction Help Resolve Streak Artifacts in Photon Counting CT?
July 22nd 2024New research looking at photon-counting computed tomography (PCCT) demonstrated significantly reduced variation and tracheal air density attenuation with polyenergetic reconstruction in contrast to monoenergetic reconstruction on chest CT.
