TOPLINE:
METHODOLOGY:
- Doxorubicin is a mainstay of Hodgkin lymphoma treatment.
- Studies suggest that girls with Hodgkin lymphoma who receive doxorubicin have a higher risk for breast cancer later in life, but it is unclear if women treated as adults face that same risk.
- To find out, investigators reviewed breast cancer incidence in 1964 Dutch women, ages 15-50, who were treated for Hodgkin lymphoma from 1975 to 2008.
- Patients had survived for at least 5 years, and 57% received doxorubicin.
TAKEAWAY:
- Women treated with doxorubicin had a 40% higher risk for breast cancer, and that risk was independent of age of treatment, receipt of chest radiation, and the use of gonadotoxic agents.
- The risk for breast cancer with doxorubicin was dose-dependent, with each 100 mg/m2 dose increment increasing the risk by 18%.
- The findings held whether women were treated years ago or more recently, despite the evolution of treatment strategies for Hodgkin lymphoma.
- After 30 years of follow-up, nearly one in five survivors (20.8%) developed breast cancer. It took 20 years for the elevated risk for breast cancer following treatment with doxorubicin to emerge.
IN PRACTICE:
The study suggests that adolescent and adult women survivors of Hodgkin lymphoma who received doxorubicin have an increased risk for breast cancer, and this risk is independent of age at first Hodgkin lymphoma treatment, receipt of chest radiotherapy, and gonadotoxic treatment, the authors concluded. “Our results have implications for [breast cancer] surveillance guidelines for [Hodgkin lymphoma] survivors and treatment strategies for patients with newly diagnosed” Hodgkin lymphoma.
SOURCE:
The study, led by Suzanne Neppelenbroek of the Netherlands Cancer Institute, Amsterdam, was published February 15 in the Journal of Clinical Oncology.
LIMITATIONS:
Recruitment ended in 2008 before the advent of newer treatments such as antibody-drug conjugates and immune checkpoint inhibitors.
DISCLOSURES:
The work was funded by the Dutch Cancer Society. Several authors reported ties to Lilly, AbbVie, Amgen, and other companies.
