- British Columbia Cancer Agency
- Brief Summary
The current standard of care for molecular characterization of tumors is tissue based next generation sequencing (NGS) panel. Liquid biopsies (ie blood) are of increasing interest and have been implemented as a diagnostic tool in some countries. This study compares tissue based and liquid based testing to evaluate the detection rate and cost consequence of using this new tool in BC.
- Detailed Description
Part A - Simultaneous - Patients will be randomized 1:1 to FoundationOne liquid CDx or no additional testing simultaneously at initiation of request for standard based tissue based next generation sequencing (NGS) panel testing. The objective of Part A is to evaluate the cost-consequence of the liquid ctDNA biopsy technology, FoundationOne liquid CDx, for first line molecular characterization of advanced colorectal cancer, melanoma, non small cell lung cancer (NSCLC), ovarian cancer, prostate cancer and triple negative breast cancer with simultaneous molecular characterization by tissue based NGS panel
Part B - Sequential - Patients will undergo standard tissue based NGS panel testing and if there are no somatic tier 1 variant of strong clinical significance identified the patients will then be eligible for FoundationOne liquid CDx. The objective of Part B is to determine the benefit of a sequential approach with molecular characterization by tissue based NGS panel testing followed by liquid based FoundationOne liquid CDx for patients who do not have an actionable tissue based oncogenic driver, across British Columbia.
The development and access to next generation sequencing (NGS) technologies on tumour tissue and blood allows the ability to profile the genomic landscape of the tumour within reasonable turn-around times and costs. The promise of precision oncology is the ability to 'match the right drug to the right patient at the right time'. Despite considerable excitement at the prospect of genome-informed therapy to improve oncologic outcomes, there has been little empirical assessment of its benefit from an overall population perspective and its true impact on cancer care delivery in 'real-world' scenarios.
While the enthusiasm for liquid biopsies has increased, the understanding of the cost implications lags behind. We propose to assess the true clinical impact on both individual patients and on a population-based cancer system of precision oncology via ctDNA analyses in metastatic solid tumors in a real-world scenario.

- Primary Outcome Measures
Name Time Method Sequential: Proportion of patients with an actionable sequencing result following uninformative standard care oncopanel results, treated at BC Cancer, outside Vancouver Centre. 24 months To evaluate the ability of FoundationOne liquid CDx to detect actionable mutations that were not identified on the tissue based NGS oncopanel.
Simultaneous: 12-month health resource utilization 12 months To compare health resource utilization of tissue based NGS panel alone, versus NGS panel and FoundationOne liquid CDx measured in Canadian dollars
- Secondary Outcome Measures
Name Time Method Sequential: Proportion of patients with insufficient tissue for molecular characterization 24 months To determine the proportion of tissue based NGS oncopanel completed for which results are not available due to insufficient tissue. To be calculated by assessing number of patients with insufficient tissue for molecular characterization over the number of patients who have molecular characterization performed
Simultaneous: Quality of Life 24 months To compare the quality of life impact of FoundationOne liquid CDx using the validated instrument, EuroQol 5 Dimension (EQ5D) (Scale of 0-100 where 0 is worst health and 100 is best health)
Sequential: Clinical utility 24 months To evaluate the clinical utility of tissue based NGS oncopanel followed by FoundationOne liquid CDx as measured by concordance/discordance of findings and subsequent treatment
Simultaneous: 18 and 24-month health resource utilization 24 months To evaluate the health resource utilization of tissue based NGS panel alone, versus panel and FoundationOne liquid CDx measured in Canadian dollars
Simultaneous: Clinical utility 24 months To evaluate the clinical utility of tissue based NGS oncopanel +/- FoundationOne liquid CDx as measured by concordance/discordance of findings and subsequent treatment
Simultaneous: Diagnostic pathway impact 24 months To assess the impact of FoundationOne liquid CDx on the diagnostic patient pathway by comparing the number of patients who require repeat biopsies for molecular characterization.
