New Delhi, Dec 02 (ANI): Researchers at LMU and Charite hospital in Berlin have developed a method for classifying difficult-to-diagnose nasal cavity tumors. The study was published in the journal, 'Nature Communications.' A team led by Dr Philipp Jurmeister and Prof. Frederick Klauschen from the Institute of Pathology at LMU and Prof. David Capper from Charite University Hospital as well as the German Cancer Consortium (DKTK) partner sites Munich and Berlin, has achieved a decisive improvement in diagnostics. Although tumors in the nasal cavity and the paranasal sinus are confined to a small space, they encompass a very broad spectrum with many tumor types. As they often do not exhibit any specific pattern or appearance, they are difficult to diagnose. This applies especially to so-called sinonasal undifferentiated carcinomas (SNUCs).
