Paclitaxel administration to gynecologic cancer patients with major cardiac risk factors.

Abstract

To examine the safety of administering paclitaxel to patients with preexisting significant cardiac risk factors. The medical records of gynecologic cancer patients with major cardiac risk factors who had been treated with paclitaxel (single-agent or combination regimen with cisplatin or carboplatin) at The Cleveland Clinic Foundation from 1993 through February 1998 were examined to determine the acute toxicity of therapy. A total of 15 patients were found who met these criteria, of whom none were found to have suffered a worsening of cardiac function following treatment with paclitaxel. A single patient developed a severe paclitaxel-associated hypersensitivity reaction, but no cardiac sequela. This series suggests that paclitaxel can be safely administered as a single agent or in a combination regimen with a platinum agent to some patients with significant cardiac risk factors, such as those associated with ischemic heart disease. However, since few patients had baseline severe conduction defects before paclitaxel treatment, the safety of this drug in this clinical setting remains to be determined.
