Descriptive Information
Brief Title Preventing Viral Pandemic Associated Risk of Cancer Death Using Less Invasive Diagnostic Tests- Liquid Biopsies
Official Title Preventing Viral Pandemic Associated Risk of Cancer Death Using Less Invasive Diagnostic Tests- Liquid Biopsies
Brief Summary The purpose of this study is to investigate the feasibility of using ctDNA to support cancer diagnosis and risk stratification where invasive aerosol generating testing (and/or tissue biopsy) is challenging due to infection risk, technical impracticalities and resource limitations, such as during the COVID-19 pandemic and the subsequent recovery period.
Detailed Description

This is a prospective, single-centre cohort pilot study using ctDNA informed treatment decisions. If the pilot study is successful within certain tumour types then this protocol may be extended to investigate further the benefit of ctDNA informed treatment decision in those tumour types.

Patients with suspected malignancy for whom invasive biopsy for definitive histological diagnosis is challenging either due to COVID-19-related resource limitations, infection control or technical feasibility will be considered for this study. In this setting liquid biopsy may be used in lieu of tissue biopsy to facilitate treatment or may be used to prioritise standard of care invasive diagnostic tests. The former includes patients who require repeat biopsies for genomic analysis following non-informative results where these would inform standard of care treatment (i.e. NICE (National Institute for Health and Care Excellence)/Cancer Drug Fund (CDF) approved drugs). Tumour types included in this study are therefore those where invasive aerosol generating diagnostic tests such as bronchoscopy, gastrointestinal endoscopy (including endoscopic ultrasound (EUS)) are part of the standard diagnostic pathway and where capacity for these tests has become severely constrained during (and likely after) the COVID-19 pandemic. Tumour types affected include some suspected biliary tract, bladder, colorectal, GIST, lung and pancreatic cancers.

The study is planned to continue until a total of 112 patients have been enrolled. This is anticipated to take up to 12-18 months. Follow-up will continue until patients have diagnosis made (based on ctDNA result) and treatment decision made (deferred or immediate).

Potential patients will be identified in and will usually at the multidisciplinary team (MDT) meeting. They will give consent to participate in the trial and offered a liquid biopsy (ctDNA) in lieu of a tissue biopsy if considered suitable for PREVAIL - ctDNA. This may include patients who require repeat biopsies for further genomic analyses when repeat biopsies are not feasible where liquid biopsy may support prioritisation for invasive diagnostics earlier. ctDNA analysis will involve copy number variant detection and low coverage whole genomic sequencing. ctDNA gene panels have already been validated against tissue based molecular diagnostics for paediatrics (ct_PAED) and colorectal cancer (ct_GI).

This analysis will be performed in an accredited clinical diagnostic laboratory (Translational Research Laboratory, Institute of Cancer Research). Patients will be stratified for treatment or further investigation based on their ctDNA result (either positive or negative), suspected tumour type, radiological (including PREVAIL-imaging risk stratification pathway) and clinical characteristics.

Study Population Patients with suspected malignancy for whom invasive biopsy for definitive histological diagnosis is challenging either due to COVID-19-related resource limitations, infection control or technical feasibility will be considered for this study
Condition
  • Neoplasm, Colorectal
  • Neoplasm of Lung
  • Neoplasm, Bladder
  • Neoplasms Pancreatic
  • Biliary Tract Neoplasms
  • Gastro Intestinal Stromal Tumour
Intervention Other: ctDNA blood sampling
Screening/baseline blood sample to be analysed for ctDNA
Study Groups/Cohorts
  • Biliary Tract Cohort
    Patients with suspected biliary tract cancer will be offered ctDNA to support a diagnosis in patients with suspected early stage, locally advanced and advanced disease. This includes patients with tumours that are technically challenging to access with invasive biopsy or due to limitations in endoscopic ultrasound due to the COVID-19 pandemic. Patients with histological diagnosis will not be eligible for this study. Patients with suspected cancer will have ctDNA result (positive or negative) discussed at MDT in conjunction with PREVAIL-imaging risk stratification pathway to risk stratify in terms of cancer risk (low, intermediate and high risk), serum tumour markers and patient presentation which will dictate the appropriate treatment. Those with metastatic disease will have their treatment decision based on ctDNA result, radiology and patient characteristics after discussion between the treating clinician and patient
    Intervention: Other: ctDNA blood sampling
  • Bladder Cancer Cohort
    Patients with suspected bladder cancer (localised and metastatic) will be offered ctDNA to support their diagnosis, in cases where cystoscopy and biopsy are difficult to obtain due to the COVID-19 pandemic. Patients with histological diagnosis will not be eligible for this study. A positive ctDNA result will be supportive of a diagnosis of bladder cancer, their treatment may be prioritised and decided based on this result in conjunction with radiological findings, patient presentation and after discussion between the treating physician and patient
    Intervention: Other: ctDNA blood sampling
  • Pancreatic Cancer Cohort
    Patients with suspected pancreatic cancer will be offered ctDNA to support a diagnosis in patients with suspected early stage, locally advanced and advanced disease. This includes patients with tumours that are technically challenging to access with invasive biopsy or due to limitations in endoscopic ultrasound due to the COVID-19 pandemic. Patients with histological diagnosis will not be eligible for this study. Patients with suspected cancer will have ctDNA result (positive or negative) discussed at MDT in conjunction with PREVAIL-imaging risk stratification pathway to risk stratify in terms of cancer risk (low, intermediate and high risk), serum tumour markers and patient presentation which will dictate the appropriate treatment. Those with metastatic disease will have their treatment decision based on ctDNA result, radiology and patient characteristics after discussion between the treating clinician and patient
    Intervention: Other: ctDNA blood sampling
  • Gastrointestinal Stromal Tumour Cohort
    Those with suspected Gastrointestinal Stromal Tumour Cohort (GIST) are eligible for this study. KIT and PDGFR mutation detected using ctDNA in conjunction with radiological features will be supportive of a diagnosis of GIST. This may allow for the use of directed targeted therapy, or prioritise surgical resection in some cases. Patients with histological diagnosis will not be eligible for this study. However, patients with inadequate tissue for KIT/PDGFR analysis will be eligible for PREVAIL-ctDNA to confirm the diagnosis of GIST and help guide treatment decisions
    Intervention: Other: ctDNA blood sampling
  • Lung Cancer Cohort
    The use of ctDNA in the diagnosis and adaptive management of patients with lung cancer is well established, however not funded by NHS. As aerosol-generating bronchoscopy procedures have reduced due to the COVID-19 pandemic, patients with suspected lung cancer may be offered ctDNA to support the diagnosis. A positive ctDNA result in conjunction with radiological findings will assist in prioritising those suitable for upfront surgical resection, radiotherapy or systemic anti-cancer treatment. It may provide sufficient genotypic information to guide standard of care targeted therapies (usually two tests are required - biopsy and then next generation sequencing of extracted DNA), including in patients without sufficient tissue for EGFR and ALK testing which can be detected using ctDNA. The use of ctDNA to guide treatment decisions in this cohort will not require signed consent as it is considered a standard approach (not yet NHS funded)
    Intervention: Other: ctDNA blood sampling
  • Colorectal Cancer Cohort
    Patients with suspected colorectal cancer will often be referred following either suspicion on imaging or faecal immunochemical testing (FIT). FIT testing results will be used to prioritise patients for screening colonoscopy, in conjunction with the PREVAIL-imaging risk stratification pathway
    Intervention: Other: ctDNA blood sampling
