Precision pharmacology: Mass spectrometry imaging and pharmacokinetic drug resistance [PDF]

open access: yes, 2019
Failure of systemic cancer treatment can be, at least in part, due to the drug not being delivered to the tumour at sufficiently high concentration and/or sufficiently homogeneous distribution; this is termed as “pharmacokinetic drug resistance”.
