Substantiation of Expressive Markers Use to Personalize Lung Cancer Chemotherapy

Abstract

Surgery results of II-III stage lung cancer remain unsatisfactory and the chemotherapy does not improve the survival. The main obstacle is the use of the standard clinical parameters for the treatment strategy and not sufficiently effective selection of regimens for the chemotherapy. Monoresistance genes defining the tumor cells sensitivity to the chemotherapeutic drugs play a significant role in development of the lung tumor resistance. The review examines the mechanisms of transport, activation and targets of the chemotherapeutic drugs, identifies the key markers for predicting their effectiveness and possible use in the clinical practice. Monoresistance genes, such as ABCC5, RRM1, ERCC1, TOP1, TOP2a, TUBB3 and TYMS are characteristic of lung cancer. Clinical trials demonstrating the efficiency of their use as predictive markers for the lung cancer chemotherapy are described. A prospective study with a personalized adjuvant chemotherapy for lung cancer patients will be performed.
