An overview of published dried blood spot (DBS) methods for the quantitation of various classes of anticancer drugs from clinical and preclinical studies is presented. The increased reporting of DBS methods in the literature for quantitation of various classes of drugs is a testimony to their utility in bioanalytical applications. While DBS offers several advantages as compared with conventional wet sampling techniques, there remain a number of nuances that may impede the assay adaptability of DBS method in routine quantitative bioanalysis. This review covers several case studies of DBS application in the quantitation of anticancer drugs. Some perspectives are provided on the optimization of the DBS method with respect to the selection of DBS card, spot volume, hematocrit effect and other regular validation parameters, which are essential in quantitative bioanalysis. Some thoughts are provided on the existing gaps in the DBS method and possible remedial measure(s) to address such gaps. Although DBS methods have great potential, there is the need for a global consensus including regulatory support on the type of validation experiments to be performed to support quantitative data.
