One pharmacogenetic sample and a series of PK samples, either intensive (<jats:italic>N<\/jats:italic>\u00a0=\u00a05; 13\u00a0samples each) or sparse (<jats:italic>N<\/jats:italic>\u00a0=\u00a043; 6\u00a0samples each), were collected from each patient. Docetaxel levels were estimated using a validated HPLC method.

Patients with abnormal alanine aminotransferase (ALT) were found to have 25% lower Cl as compared to patients with normal ALT values.
