Although current cancer genomic profiling tests are powerful tools to predict the efficacy of molecular targeted drugs or immune checkpoint inhibitors, they are not readily applicable for classical anticancer agents. In this study, we report a novel concept of phenotype\u2010based classification using machine learning analysis of gene expression patterns to predict the effectiveness of anticancer agents.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Hierarchical clustering of IC\n                      <jats:sub>50<\/jats:sub>\n                      values distinguished cisplatin\u2010sensitive and resistant cell lines.
