Patient Preferences for Use of Archived Biospecimens from Oncology Trials When Adequacy of Informed Consent Is Unclear.

BACKGROUND: Oncology research increasingly involves biospecimen collection and data sharing. Ethical challenges emerge when researchers seek to use archived biospecimens for purposes that were not well defined in the original informed consent document (ICD). We sought to inform ongoing policy debates by assessing patient views on these issues. MATERIALS AND METHODS: We administered a cross-sectional self-administered survey to patients with cancer at an academic medical center. Survey questions addressed attitudes toward cancer research, willingness to donate biospecimens, expectations regarding use of biospecimens, and preferences regarding specific ethical dilemmas. RESULTS: Among 240 participants (response rate 69%), virtually all (94%) indicated willingness to donate tissue for research. Most participants (86%) expected that donated tissue would be used for any research deemed scientifically important, and virtually all (94%) expected that the privacy of their health information would be protected. Broad use of stored biospecimens and data sharing with other researchers increased willingness to donate tissue. For three scenarios in which specific consent for proposed biobank research was unclear within the ICD, a majority of patient's favored allowing the research to proceed: 76% to study a different cancer, 88% to study both inherited (germline) and tumor specific (somatic) mutations, and 70% to permit data sharing. A substantial minority believed that research using stored biospecimens should only proceed with specific consent. CONCLUSION: When debates arise over appropriate use of archived biospecimens, the interests of the research participants in seeing productive use of their blood or tissue should be considered, in addition to addressing concerns about potential risks and lack of specific consent. IMPLICATIONS FOR PRACTICE: This survey evaluated views of patients with cancer regarding the permissible use of stored biospecimens from cancer trials when modern scientific methods are not well described in the original informed consent document. The vast majority of patients support translational research and expect that any biospecimens they donate will be used to advance knowledge. When researchers, policy makers, and those charged with research oversight debate use of stored biospecimens, it is important to recognize that research participants have an interest in productive use of their blood, tissue, or data, in addition to considerations of risks and the adequacy of documented consent.

Secondary Use of Patient Tissue in Cancer Biobanks.

BACKGROUND: As scientific techniques evolve, historical informed consent forms may inadequately address modern research proposals, leading to ethical questions regarding research with archived biospecimens. SUBJECTS, MATERIALS, AND METHODS: We conducted focus groups among patients with cancer recruited from Massachusetts General Hospital to explore views on medical research, biobanking, and scenarios based on real biospecimen research dilemmas. Our multidisciplinary team developed a structured focus group guide, and all groups were recorded and transcribed. Transcripts were coded for themes by two independent investigators using NVivo software. RESULTS: Across five focus groups with 21 participants, we found that most participants were supportive of biobanks and use of their own tissue to advance scientific knowledge. Many favor allowing research beyond the scope of the original consent to proceed if recontact is impossible. However, participants were not comfortable speaking for other patients who may oppose research beyond the original consent. This was viewed as a potential violation of participants' rights or interests. Participants were also concerned with a "slippery slope" and potential scientific abuse if research were permitted without adherence to original consent. There was strong support for recontact and reconsent when possible and for the concept of broad consent at the time of tissue collection. CONCLUSION: Our participants support use of their tissue to advance research and generally support any productive scientific approach. However, in the absence of broad initial consent, when recontact is impossible, a case-by-case decision must be made regarding a proposal's potential benefits and harms. Many participants support broad use of their tissue, but a substantial minority object to use beyond the original consent. IMPLICATIONS FOR PRACTICE: For prospective studies collecting tissue for future research, investigators should consider seeking broad consent, to allow for evolution of research questions and methods. For studies using previously collected tissues, researchers should attempt recontact and reconsent for research aims or methods beyond the scope of the original consent. When reconsent is not possible, a case-by-case decision must be made, weighing the scientific value of the biobank, potential benefits of the proposed research, and the likelihood and nature of risks to participants and their welfare interests. This study's data suggest that many participants support broad use of their tissue and prefer science to move forward.

Cluster Analysis Demonstrates the Need to Individualize Care for Cancer Survivors.

BACKGROUND: In efforts to inform clinical screening and development of survivorship care services, we sought to characterize patterns of health care needs among cancer survivors by (a) identifying and characterizing subgroups based on self-reported health care needs and (b) assessing sociodemographic, clinical, and psychosocial factors associated with these subgroups. METHODS: We conducted a cross-sectional self-administered survey among patients presenting for routine follow-up care for early-stage cancer at our academic medical center. Latent class cluster analysis was used to identify clusters of survivors based on survivorship care needs within seven domains. Multiple logistic regression analyses were used to assess factors associated with these clusters. RESULTS: Among 292 respondents, the highest unmet needs were related to the domains of side effects (53%), self-care (51%), and emotional coping (43%). Our analysis identified four clusters of survivors: (a) low needs (n = 123, 42%), (b) mainly physical needs (n = 46, 16%), (c) mainly psychological needs (n = 57, 20%), and (d) both physical and psychological needs (n = 66, 23%). Compared with cluster 1, those in clusters 2, 3, and 4 were younger (p < .03), those in clusters 3 and 4 had higher levels of psychological distress (p < .05), and those in clusters 2 and 4 reported higher levels of fatigue (p < .05). CONCLUSION: Unmet needs among cancer survivors are prevalent; however, a substantial group of survivors report low or no health care needs. The wide variation in health care needs among cancer survivors suggests a need to screen all patients, followed by tailored interventions in clinical care delivery and research. IMPLICATIONS FOR PRACTICE: The characterization of patients as having few needs, predominantly physical needs, predominantly psychological needs, or substantial needs that are both physical and psychological provides a productive framework for clinical care of cancer survivors and to guide further research in this field. Further research is needed to define the tailored information and services appropriate for each group of patients and to define optimal screening tools to efficiently identify the needs of individuals in oncology practice.

Fear of Cancer Recurrence: A Model Examination of Physical Symptoms, Emotional Distress, and Health Behavior Change.

PURPOSE: Fear of cancer recurrence is highly prevalent among adult survivors of cancer. The role of fear of recurrence in the emotional distress of survivors of cancer, as well as health behaviors that may directly affect their health, remains unclear. To advance oncology practice, this study sought to examine the extent to which fear of recurrence stemming from physical symptoms accounts for emotional distress in a large sample of adult survivors of cancer and to extend the model to explain postdiagnosis self-reported health behavior change. METHODS: In 2016, 258 survivors of cancer at an academic hospital completed a survey of psychosocial needs. Items assessed physical symptoms (checklist), fear of cancer recurrence (Assessment of Survivor Concerns), emotional distress (anxiety and depressed mood), and health behaviors (current alcohol use, physical activity, diet, and sunscreen use, as well as changes after cancer diagnosis) informed by National Comprehensive Cancer Network survivorship guidelines. Indirect effects regression models accounting for relevant covariates (age and treatment history) used 5,000-iteration bootstrapping. RESULTS: Higher fear of cancer recurrence was associated with greater number of physical symptoms (P < .001), greater emotional distress (P < .05), lower moderate or vigorous physical activity (P < .05), higher sunscreen use (P < .05), and postdiagnosis increases in alcohol use (P < .01) and reductions in physical activity (P < .01). Fear of cancer recurrence models accounted for almost half of the variance in distress of survivors of cancer (R2 = 0.44, P < .001) and, to a lesser yet significant extent, changes in alcohol consumption (R2 = 0.09, P < .001) and physical activity (R2 = 0.06, P = .003). CONCLUSION: Fear of cancer recurrence plays a central role in the emotional distress and key health behaviors of survivors of cancer. These findings support fear of cancer recurrence as a potential target for emotional health and health behavior change interventions.
