The department takes samples of tumour tissue, processes these samples, prepares histological preparations, and performs histochemical and immunohistochemical staining as well as fluorescent in situ hybridisation. Employees perform histological diagnostics, cooperate in multidisciplinary teams and medical councils, take part in trainings for technicians, engineers, pathology residents, and pathology and other specialists, and they cooperate in national and international trials.

They introduced many new immunohistochemical and FISH examinations that enable the modern diagnostics of tumours and identification of biological markers that are decisive for determining the suitable patient treatment (CD20, CD30, ER, PR, MIB-1, ALK, HER2, MMRP, PD-L1, etc.). They regularly participate in multiple external quality-control schemes, in which they receive excellent reviews for the above examinations. By establishing multi-tumour networks, they cooperate in different IO studies; they test new antibodies and create internal quality control protocols for our trials and research.
