High-resolution CT and histopathology combination enhances accuracy of ILD diagnosis: Study

Japan: A combination of high-resolution CT (HRCT) and histological patterns enhances the ability of radiologists to diagnose interstitial lung disease (ILD), a recent study has stated. This helps in providing appropriate treatment to patients with lung cancer who presented with ILD. The study appears in General Thoracic and Cardiovascular Surgery. 

Interstitial lung disease can manifest in several ways, and each of them has different pathophysiology. One of these is idiopathic interstitial pneumonia (IIP) which then has a common subtype of idiopathic pulmonary fibrosis (IPF) that is related to poor patient outcomes. Patients with interstitial lung disease have high lung cancer rates and higher rates of morbidity as a result of lung cancer treatment. And, are also at risk of complications that develop within a month following surgical treatment. 

Against the above background, Akira Iyoda, Toho University School of Medicine, Ota-ku, Tokyo, Japan, and colleagues aimed to determine the prognostic impact of interstitial lung disease subclassification based on both high-resolution computed tomography (HRCT) scan findings and histopathological findings.

For this purpose, the researchers retrospectively analyzed 104 patients who were diagnosed with clinical ILD in accordance with HRCT scan findings and who underwent lung cancer surgery. HRCT scan findings were re-classified and histopathological patterns of ILDs in lung specimens were validated via an expert multidisciplinary discussion.
