Within this population, physician-based ultrasound-guided cutting-needle pleural biopsy obtains pleural tissue successfully in a high proportion of cases.

Scientists comparing two methods of obtaining pleural tissue for mesothelioma diagnosis say the less-invasive method may be a good option for certain patients. Details of the study have just been posted on Surviving Mesothelioma and can be read by clicking here.
Researchers at the Centre for Respiratory Medicine at Oxford University analyzed 50 ultrasound-guided cutting-needle biopsies performed at their center for suspected mesothelioma. Although a more invasive procedure called thoracoscopy produces a larger tissue sample, the team says the needle method may be better for mesothelioma patients with certain complications.
“[Thoracoscopy] is not always possible in frail patients, if pleural fluid is heavily loculated, or where the lung is adherent to the chest wall,” writes lead author Rob Halifax, MSc. “Such cases can be converted during the same procedure as attempted thoracoscopy to cutting-needle biopsy.”
The study, published in the journal Chest, found that 84.6% of samples taken with the cutting-needle method were sufficient to make a mesothelioma diagnosis, or to rule it out.
“These results should be reassuring for patients who aren’t candidates for thoracoscopy that they can still get a definitive diagnosis,” says Surviving Mesothelioma’s Managing Editor Alex Strauss. Tissue biopsy remains the only way to definitively diagnose mesothelioma.
