The 2014 program is an exciting combination of science, technology, research importance of proteomics and peptidomics, mRNA and circulating tumour cel s including established techniques (EBUS, transbronchial biopsy and radial probe and supportive care. The meeting is hosting 7 international experts from the specialties representing the for diagnosing and monitoring lung cancer. He believes they are very important EBUS biopsy).
