A significant proportion of patients being investigated for malignant disease will have malignancy despite a negative CT report.
Raleigh, NC (PRWEB) August 06, 2014
Scientists at two tertiary referral centers are suggesting that CT scans may not be accurate enough as a means of deciding whether to perform a surgical biopsy in patients with a suspected pleural cancer like mesothelioma.

Doctors with Oxford University and Lancashire Teaching Hospitals in Preston, UK, compared CT results with actual biopsy results in 370 patients suspected of having a respiratory cancer like pleural mesothelioma. They say CT alone may not be enough to determine who should get a definitive answer through surgery.
Lead researcher Dr. Rob Hallifax of Oxford writes, “A significant proportion of patients being investigated for malignant disease will have malignancy despite a negative CT report.”
The report in the journal Thorax found that CT was 68% accurate in correctly identifying malignancies and 78% accurate in determining which patients did not have cancer.
“CT is a major part of the diagnostic process for malignant pleural mesothelioma, but this study suggests that it should not be the only means of deciding which patients should undergo surgical biopsy,” says Surviving Mesothelioma Managing Editor Alex Strauss. Biopsy is currently the only way to make a definitive diagnosis of mesothelioma.
