Disclosed are methods of enhancing the uptake of a therapeutic agent in a target tissue as well as methods of treating a disease (such as cancer) or enhancing effectiveness of treatment with a therapeutic agent in an individual by co-administering a composition comprising nanoparticles comprising albumin and a poorly water soluble drug such as a taxane with the therapeutic agent. Also disclosed is a method of treatment or a method of selecting patients for treatment of a disease (such as cancer) with the combination of a therapeutic agent and a composition comprising nanoparticles comprising albumin and a poorly water soluble drug such as a taxane based on one or more characteristics of the target tissue that correlates or indicates the capability of getting enhanced therapeutic agent uptake as a result of the co-administration of the taxane nanoparticle composition in the target tissue (referred to as &ldquo；the drug uptake capability&rdquo；).
