Abstract

Targeted therapy has become an important modality of cancer treatment in the last decade. Drugs against EGFR and HER2 e.g. erlotinib, cetuximab or trastuzumab proved its role n therapy. They are managed as registered and recommended modalities of lung, alimentary tract and breast carcinoma. Significance of targeted treatment is a common effect of drug action and patient selection. Only a part of patients with tumors belonging to a specific histological type of cancer can benefit from targeted therapy. Determining predictive factor — informating on potential response to therapy — is essential for proper treatment in targeted therapy. Patients’ selection is accomplished by pathological methods with help of molecular biology techniques. Patient selection for targeted treatment and predictive factors evaluation criteria as well as establishing connections with traditional tumor characteristics (e.g. histological type, grade, stage) are continuously under research. Predictive factors are also investigated for traditional chemotherapeutics in recent years. Value of particular predictive factor depends on choice of evaluation method.
