Medical Spotlight: Dr. Richard Proia on Advanced Technology for Lung Cancer



now from your local source TV 20 news 530 live in high definition they are boldly going where no doctor has gone before the deepest recesses of human lung from the inside doctors can identify whether or not a patient has lesions on their lungs but there were roadblocks and getting a biopsy from inside the farthest reaches of the lungs that is until now in tonight's medical spotlight David finds out how doctors are using a new road map to identify lung cancer earlier than ever before thanks Paige I'm joined tonight by dr. Richard poya he's a cardiothoracic surgery North Florida Regional Medical Center how are lesions on the lung identified in the first place and then found whether or not they're cancerous well it usually starts out with someone getting a chest x-ray which then leads to a cat scan for some abnormality and a lot of times it's found incidentally because there's no real true screening for lung cancer right now and to get those lesions to get a biopsy you currently use a bronchoscopy a procedure correct and how does that go and what are the limits of it well bronchoscopy is one way to get a biopsy and with standard bronchoscopy you have a bronchoscope which has a diameter of about two and a half or three millimeters so you can only get so far down into the reaches of the lung Airways with this newer technique we have a smaller gauge catheter which can get down in smaller Airways and it's only about a millimeter in diameter well how does this work it's called electromagnetic navigation bronchoscopy how does it go further well basically what you do is you get the bronchoscope the standard bronchoscope in as far as you can the way you normally do and then you place this locatable guide in and using an electromagnetic field you're able to navigate your way into the smaller Airways and get either biopsies or even place a marker around this lesion if you are going to give them radiation at a later time how much planning ahead does it take for this procedure because you're not actually able to use a little camera right right so what you do is you have to get a special protocol type CT scan of the patient before you actually do the procedure so that you have very thin cuts and very fine detail the lung itself and then from that you plan your route using a special computer and software is this procedure easier on the patient and other similar procedures well it's fairly non-invasive in the sense that you're not cutting or making any incisions you are going down through their airway though and essentially after the procedure they shouldn't have any real untoward effects from it the complication rate is fairly low well how quickly does a patient recover from from it's the same day procedure they come in the day of the procedure and then leave that same day so they should be feeling good later that same day or within another day or two afterwards alternative procedures to this are there are many to choose from yeah you can get biopsies of the lung in other ways which are not quite as easy on them there's a where you can go with a needle through the chest wall itself from the outside that's done using CT guidance as well but as you can imagine there could be complications with placing that needle or even puncturing the lung and having the lung collapse so something might get in the way as he actually reached the lawn you might hit something you didn't want a we certainly don't want that to happen okay thank you so much dr. richard coyle of North Florida Regional Medical Center page back to you
