PCRC Best Supportive Care (PCRC BSC)

Overview

The primary objective of this study is to formalize the delivery of BSC in advanced cancer trials. The first aim (to develop expert-derived consensus statements regarding components of supportive care in cancer clinical trials) and the second aim (to compare the extent to which documentation of current supportive care delivery in trials compares to the consensus statements) have been completed. The final aim of this study is to test the feasibility of thorough documentation of BSC delivery. That work is proposed as the primary aim of this study.

Many cancer clinical trials are designed to evaluate the benefits of experimental anticancer drugs against best supportive care (BSC); many drugs have been registered based on very modest survival advantages when compared with BSC. Universally across these studies, however, BSC control arms have not been standardized across sites in the way that trialists strive to standardize other interventions in clinical trials; are not consistent with contemporary palliative care practice; are not based on the extensive best available evidence; and are not described in any detail in most cases and certainly not sufficient detail to reproduce in subsequent studies. When reporting of BSC in trials is incomplete, the resulting data have uncertain internal and external validity. Such poorly defined interventions and variation between sites is unacceptable for other aspects of a clinical trial. Furthermore, a poorly delivered BSC arm might systematically overestimate the performance of the intervention arm(s) in the study leading to poor decision making by clinicians and funders. With mounting evidence that early use of supportive/palliative care can improve patient outcomes, incomplete delivery of BSC might deprive patients of considerable benefit, potentially in the setting of far less toxicity. In line with the CONSORT statement on reporting of clinical trials, our proposed study would seek to generate consensus-based standards for BSC definition (allowing this to be updated as new evidence becomes available), operationalize and measure outcomes in a clinical trial setting. In doing so, we intend to demonstrate: 1) the feasibility of thorough documentation of BSC, its delivery and measurement in a clinical trial; and 2) improved quality of life over standardized BSC. Specifically in terms of PCEOL research objectives, this study will develop an intervention designed to mitigate adverse physical and psychological symptoms and outcomes that focus especially on the beginning of the end-of-life phase. This will be a prospective, single arm before and after consecutive cohort study of oncologists and patients. Initially, individual and institutional best practice in terms of supportive/palliative care delivery will be recorded across all sites (control period). Two months into study initiation, patients will complete pre-intervention patient ESAS and PNPC-sv assessment to measure their baseline care experience. At that point, all sites will simultaneously switch to the behavioral modification intervention (BSC checklist; experimental period). From that time forward, documentation of supportive care delivery will be documented via the BSC checklist and medical record review. At month four, physician acceptability and patient experience will be evaluated.
