Abstract
Purpose
The practice of seeking a biopsy to confirm a metastatic relapse of a prior breast cancer is individualized. Tumor samples have well-recognized importance in clinical and translational research, but also an increasing role in routine care. We sought to determine the attitudes of patients and breast cancer clinicians about biopsy at breast cancer relapses.
Methods
Consenting breast cancer patients and clinicians completed questionnaires with scenarios of decreasing personal benefit and increasing discomfort or inconvenience associated with biopsy at relapse of a prior breast cancer. For each scenario, patients were asked whether they would, would not, or were unsure about agreeing to a biopsy. Clinicians provided information about their practice, research activities, and usual biopsy habits. They were asked to estimate how often patients would agree to a biopsy under each of the conditions presented to patient participants.
Results
The majority of patients expressed a willingness to undergo a biopsy procedure of modest inconvenience and discomfort to establish an uncertain diagnosis, guide treatment, to participate in a trial, or for research purposes only. About 50% of patients indicated that they would undergo an invasive biopsy procedure requiring IV sedation or general anesthetic for purely altruistic reasons. In spite of being a largely academic group, clinician respondents underestimated patient willingness to have a biopsy in all scenarios, particularly when there was no attached personal benefit.
Conclusion
Breast cancer patients were very willing to undergo biopsy at breast cancer relapse for their routine care, clinical trials, or for research only. Clinicians act as the intermediary between patients and tumor tissue repositories, and clinician perceptions and practices should shift to match the altruistic attitudes of breast cancer patients.
