: All patients received
chemotherapy during the course of the study, beginning with a
platinum-based doublet (74%), an oral epidermal growth factor
receptor–tyrosine kinase inhibitor (14%), or a parenteral single
agent (12%). Forty percent (n=20) of patients had a dose delay
(38%) and/or reduction (16%) in their scheduled infusions.
Fisher's Exact Tests and regression analyses showed that patients
who experienced neutropenia, smoked at the time of diagnosis, or
reported heightened baseline anxiety were significantly more
likely to experience dose delays or reductions. There were no
associations between chemotherapy adherence and patient demographics,
performance status, or quality of life
