Abstract

Insights

Nurses can manage everolimus-induced stomatitis in advanced breast cancer patients. Steroid-based mouth rinses and other strategies improve patient outcomes and reduce treatment interruptions.

Area of Science:

  • Oncology
  • Pharmacology
  • Nursing Education

Background:

  • Everolimus, a mammalian target of rapamycin (mTOR) inhibitor, is used for advanced hormone receptor-positive, HER2-negative breast cancer resistant to endocrine therapy.
  • Stomatitis is a common dose-limiting side effect of everolimus, often leading to treatment discontinuation or dose reduction.

Purpose of the Study:

  • To educate nurses on identifying and managing stomatitis in patients with hormone receptor-positive advanced breast cancer treated with mTOR inhibitors.
  • To provide strategies for improving patient outcomes through effective stomatitis management.

Main Methods:

  • Literature review focusing on stomatitis incidence, identification, and management in cancer, specifically breast cancer.
  • Description of clinical experiences in managing stomatitis at the authors' cancer center.

Main Results:

  • Clinical evidence supports the efficacy of steroid-based mouth rinses as an adjunct treatment for stomatitis.
  • Clinical experience offers practical insights into preventive and management strategies for everolimus-induced stomatitis.

Conclusions:

  • Effective management of stomatitis is crucial for patients receiving everolimus for advanced breast cancer.
  • Implementing evidence-based and experiential strategies can improve patient adherence and outcomes.
