Endoscope with an oxygen sensor detects pancreatic cancer

An optical blood oxygen sensor attached to an endoscope is able to identify pancreatic cancer in patients via a simple endoscopic procedure, according to researchers at Mayo Clinic in Florida.

The study shows that the device, which acts like the well-known clothespin-type finger clip used to measure blood oxygen in patients, has a sensitivity of 92 percent and a specificity of 86 percent.

That means, of 100 patients with pancreatic cancer, this sensor would detect 92 of them, based on the findings. And of 100 patients who don
