The Rollercoaster of Paclitaxel in the Lower Limbs and Skeletons in the Closet: An Opinion Review.

There have been concerns about the long-term risk of all-cause death with the use of paclitaxel-coated devices in the lower limbs. Results from a 2018 meta-analysis were corroborated by the US Food and Drug Administration and later confirmed by an individual patient data meta-analysis. However, population-based observational studies have produced contradictory results and often claimed a survival benefit with the use of paclitaxel. The recently published Swedish drug-elution trial in peripheral arterial disease did not confirm a significant mortality risk. In this review, the authors discuss the key elements of the identified mortality signal and stress important facts and figures that remain underrecognized and elusive. They also highlight the important types of epidemiological bias that pertain to the ongoing debate on paclitaxel.
