Cell Culture Based Test Systems for Anticancer Drug Screening.

The development of new high-tech systems for screening anticancer drugs is one of the main problems of preclinical screening. Poor correlation between preclinical and data with clinical trials remains a major concern. The choice of the correct tumor model at the stage of testing provides reduction in both financial and time costs during later stages due to the timely screening of ineffective agents. In view of the growing incidence of oncology, increasing the pace of the creation, development and testing of new antitumor agents, the improvement and expansion of new high-tech systems for preclinical screening is becoming very important. The pharmaceutical industry presently relies on several widely used models, including two-dimensional models, three-dimensional models, microfluidic systems, Boyden's chamber and models created using 3D bioprinting. This review outlines and describes these tumor models including their use in research, in addition to their characteristics. This review therefore gives an insight into based testing which is of interest to researchers and clinicians from differing fields including pharmacy, preclinical studies and cell biology.
