Biospecimens are invaluable lynchpins in translational oncology, both to engender new discoveries and to assess the efficacy of new treatment paradigms. The collection and use of such specimens rely upon the patients and subjects who entrust clinicians with their bodies. This is especially true for research biopsies that are solely performed to enhance scientific understanding and may not offer any benefit to the individual patient or subject. An ethical framework was recently developed by the American Society of Clinical Oncology (ASCO) to improve and inform the procurement of research biopsies in clinical trials. By considering their potential to increase scientific knowledge, the inherent risk of their collection, and whether they are required for clinical management, these guidelines assign weighted utility to biopsies [1]. Although the ASCO guidelines serve as an excellent model for researchers and clinicians alike, how they will be implemented in practice remains uncertain. It is thus critical to understand the guidelines, as well as to identify barriers to their use, especially as research biopsies become an increasingly common component of clinical trials. In this issue of The Oncologist, Olympios et al. examine requests and consent for research biopsies in a series of clinical trials designed prior to the publication of the ASCO Ethical Framework [2]. Notably, only 39% of clinical trials requiring mandatory biopsies would have been compliant with the subsequently published framework. The authors assessed several study attributes to determine compliance with the ASCO framework, including the potential utility of the biopsy, the risk for patients, and the mandatory or optional request for biopsy. Informed consent forms were analyzed for thoroughness regarding biopsy risk and explanation of the scientific rationale. Multiple studies requested biopsy for exploratory objectives. Other reasons for lack of compliance included inadequate statistical analyses or disproportionate risk. Olympios et al. also report that the amount of risk of research biopsies was often inadequately described in informed consent documents. This study highlights the need for critical reappraisal of current practices and how we can best respect and serve our existing patients while advancing the science necessary to improve the care of future patients like them. With the growing impetus to identify predictive biomarkers in the era of precision medicine, it is essential to critically assess the implications of research biopsies in clinical trials. We offer a discussion on the risk-benefit analysis of inclusion of research biopsies in clinical trials, the inherent tensions for dual clinician researchers, and questions for an age of increasing commercialization of patient information.
