Testing algorithm integrating diagnostic and predictive analysis in nonsmall cell lung cancer (NSCLC). Testing algorithm integrating diagnostic and predictive analysis in nonsmall cell lung cancer (NSCLC). Note the financial implication: the costs for predictive testing are added to those for diagnostic testing.
