Connective tissue: Cancer patients’ attitudes towards medical research using excised (tumour) tissue

Abstract

The objective of this article is to explore the views of Dutch cancer patients on the use of excised and stored (tumor) tissues in medical research. Excised tissues are routinely stored in hospitals for future diagnostic use. They are also important for scientific research. This article discusses and interprets concepts of 'ownership' in the context of the increasing scientific and commercial value of tissues. We used a mixed-methods design combining quantitative data (questionnaires) with qualitative data (interviews) and observations during an intervention study. Our analysis suggests that, for patients, the stored tissue is a hypercollective good that should remain in the public sphere in order to facilitate research. The tissue is seen as connecting the donor to relatives and other patients, the hospital, and to the larger scientific community. The respondents expressed a preference for an ongoing relationship with the tissue custodian. A substantial minority of respondents consider themselves to be owners of the tissue. Notably, tumour tissue is perceived as unique and special. Patients endorse the use of extracorporeal tissue removed during medical care in scientific research. They expect reciprocity from the tissue custodian in the form of information about findings.

Towards ‘Engagement 2.0’: Insights from a study of dynamic consent with biobank participants

“… 7 , 8 This includes studies designed to gauge the attitudes of various publics to biobanking projects, 9 – 11 and research on the views and motivations of actual and potential biobank participants. 12 – 16 Studies have also addressed key concerns such as broad consent, trust, reciprocity and the use of Web 2.0 technology.…”

The sociology of cancer: a decade of research

“…This challenges the lack of regard for participants' lived experiences, particularly evident in paradoxes that arise from the removal of individual particulars from death statistics, 'ghosting' their lives (Jain 2010). The informed consent process is also a focus of critical analysis, including the ways in which it is used to manage the conflicts of interest in research and clinical care in cancer genetics clinics (Hallowell et al 2009), and the dangers of its operation as a 'technical fix' which does not capture the complexities of how patients make decisions about trial or other research participation in practice (Armstrong et al 2012, Vermeulen et al 2011.…”

“…In addition, tumor tissues from the Erasmus MC (Rotterdam, the Netherlands) were used according to the code of conduct, Proper Secondary Use of Human Tissue, established by the Dutch Federation of Medical Scientific Societies. 35…”
