Cancer Patient-Reported Preferences and Knowledge for Liquid Biopsies and Blood Biomarkers at a Comprehensive Cancer Center.

ABSTRACT: Background:Blood-based biomarkers (liquid biopsy) are increasingly used in precision oncology. Yet, little is known about cancer patients' perspectives in clinical practice. We explored patients' depth of preferences for liquid vs tissue biopsies and knowledge regarding the role of blood biomarkers on their cancer. Methods:Three interviewer-administered trade-off scenarios and a 54-item self-administered questionnaire were completed by cancer outpatients across all disease sites at the Princess Margaret Cancer Centre. Results:Of 413 patients, 54% were female; median age was 61 (range 18-101) years. In trade-off scenario preference testing, 90% (n=372) preferred liquid over tissue biopsy at baseline; when wait times for their preferred test were increased from 2 weeks, patients tolerated an additional mean of 1.8 weeks (SD 2.1) for liquid biopsy before switching to tissue biopsy (with wait time 2 weeks). Patients also tolerated a 6.2% decrease (SD 8.8) in the chance that their preferred test would conclusively determine optimal treatment before switching from the baseline of 80%. 216 patients (58%) preferred liquid biopsy even with no chance of adverse events from tissue biopsy. Patients' knowledge of blood-based biomarkers related to their cancer was low (mean 23%); however, the majority viewed development of blood biomarkers as important. Conclusion:Patients had limited understanding of cancer-specific blood-based biomarkers, but 90% preferred liquid over tissue biopsies to assess biomarkers. There was little tolerance to wait longer for results, or for decreased test-conclusiveness. Developing accurate, low-risk tests for cancer diagnosis and management for blood biomarkers is therefore desirable to patients.

Project description:BackgroundDespite evidence of the positive impact of routine assessment of patient-reported outcome measures (PROMs), their systematic collection is not widely implemented in cancer care.AimTo assess the knowledge, use and attitudes of healthcare professionals (HCPs) towards PROMs and electronically collected PROMs (ePROMs) in clinical practice and research and to explore respondent-related factors associated with the above dimensions.MethodAn ad hoc developed online survey was administered to all HCPs employed in clinical activity in an Italian comprehensive cancer center. The survey investigated which PROMs were known and used, as well as HCPs' opinions on the advantages and drawbacks of routine PROM assessment, including electronic assessment (ePROM). Linear and logistic regression models were used for association analyses.ResultsFive Hundred Eleven of nine hundred ninety-two invited HCPs (52%) provided analyzable responses. 68% were women, 46% were nurses and 42% physicians, and 52.5% had > 20 years seniority. The average number of PROMs known was six among 17 proposed. All proved to be under-used (< 28%) except unidimensional and multidimensional pain scales (77 and 36%). Respondents expressed an overall positive attitude towards PROMs, with strengths outweighing weaknesses (mean overall scores 3.6 and 2.9, respectively, on a 1-5 scale). 67% of respondents preferred electronic collection over paper and pencil. Profession was associated with knowledge and use (physicians reported knowing more PROMs than other professionals) and with a preference for electronic collection (nurses were less likely to prefer the electronic format than physicians). Senior HCPs were slightly more critical about both PROMs and electronic administration.ConclusionsThis survey indicates an acceptable level of knowledge of common PROM tools but low usage in practice. Based on the generally positive attitude of HCPs, routine implementation of ePROMs can be promoted as long as adequate resources and training are provided.Trial registrationNot registered.

Project description:PurposeThe use of integrative approaches for symptom management is highly prevalent among patients undergoing cancer treatment and among cancer survivors and is increasingly endorsed by clinical practice guidelines. However, access to and implementation of integrative oncology (IO) approaches are hindered by barriers at multiple levels, including logistic, geographic, financial, organizational, and cultural barriers. The goal of this mixed-method study was to examine oncology provider and patient knowledge, beliefs, and preferences in IO to identify facilitators, barriers, and recommendations for implementation of IO modalities.Materials and methodsData sources included patient surveys and provider semistructured interviews. Patients were in active treatment (n = 100) and survivors (n = 100) of heterogeneous cancer types. Patient and survivor surveys interrogated: (1) interest in types of IO approaches; and (2) preferences for delivery modality, frequency, and location. Providers (n = 18) were oncologists and nurse navigators working with diverse cancer types. Interviews queried their knowledge of and attitudes about IO, about their patients' needs for symptom management, and for recommendations for implementation of IO approaches in their clinic. We used the Consolidated Framework for Implementation Research framework to systematically analyze provider interviews.ResultsThe primary interests reported among actively treated patients and survivors were massage therapy, acupuncture, and wellness/exercise. Most patients expressed interest in both group and individual sessions and in telehealth or virtual reality options. Emergent themes from provider interviews identified barriers and facilitators to implementing IO approaches in both the internal and external settings, as well as for the implementation process.ConclusionThe emphasis on mind-body interventions as integrative rather than alternative highlights the importance of interventions as evidence-based, comprehensive, and integrated into health care. Gaining simultaneous perspectives from both patients and physicians generated insights for the implementation of IO care into complex clinical systems within a comprehensive cancer center.
