About this study

Official title: Questionnaire on Congenital Cancer Signs Through Self-Assessment (QUOCCAS)

This clinical trial tests whether a patient- and caregiver-completed questionnaire (QUOCCAS) can accurately help identify children and adolescents with cancer who may have an underlying cancer predisposition syndrome (CPS). The study will also evaluate whether providing families with an educational brochure before their clinic visit improves their understanding of genetics and their satisfaction with care.

The main questions it aims to answer are:

Read more
  • Does QUOCCAS identify children at risk for CPS as accurately as physician-based tools and compared to genetic testing?
  • Does the Pre-Visit Preparation (PVP) brochure improve caregiver knowledge about genetics?
  • Does the PVP brochure improve caregiver satisfaction with the care and information they receive?

Participants will:

  • Complete the QUOCCAS questionnaire about family history, clinical features, and cancer signs
  • Provide a blood or saliva sample for genetic testing (whole-exome or whole-genome sequencing)
  • Randomly receive or not receive the educational Pre-Visit Preparation brochure before completing the questionnaire
  • Complete brief surveys on their knowledge and satisfaction

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Pre-Visit Preparation (PVP) BrochureBehavioural

    Also called Educational Brochure

    Participants receive a Pre-Visit Preparation (PVP) brochure containing information about cancer predisposition syndromes, genetic testing, and implications for care. The brochure is provided before completion of the QUOCCAS questionnaire and is designed to improve caregiver knowledge, engagement, and satisfaction with care.

  • QUOCCAS QuestionnaireDiagnostic test

    Also called Questionnaire on Congenital Cancer Signs through Self-Assessment

    Participants complete the QUOCCAS questionnaire, a structured, self- or caregiver-reported tool designed to identify clinical features, family history, and signs suggestive of cancer predisposition syndromes. Responses are used to classify risk status and are compared against physician-based tools and genetic testing (germline genetic sequencing).

  • Germline genetic sequencing for Cancer Predisposition Syndromes (CPS)Diagnostic test

    All participants will provide a saliva or blood sample for germline genetic sequencing. The investigators will perform either whole-exome (WES) or whole-genome sequencing (WGS) and assess for pathogenic/ likely-pathogenic variants in known Cancer Predisposition Genes (CPS).

  • MIPOGG AssessmentDiagnostic test

    The McGill Interactive Pediatric OncoGenetic Guidelines (MIPOGG) is a clinician-applied digital decision-support tool that uses patient age, tumor type, and clinical features to generate recommendations for referral to genetics. In this study, all participants will undergo MIPOGG assessment performed by the research team through the use of medical records. Results will be compared with those from the QUOCCAS questionnaire to evaluate concordance and potential equivalence in identifying children with cancer predisposition syndromes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Sensitivity and Specificity of the QUOCCAS Questionnaire for Identifying Cancer Predisposition Syndromes (CPS)

    Accuracy of the QUOCCAS questionnaire in identifying childhood cancer patients at increased risk for a cancer predisposition syndrome, compared to (1) physician standard of care referral, (2) the McGill Interactive Paediatric Oncogenetic Guidelines (MIPOGG), and (3) the gold standard of germline genetic sequencing. Sensitivity is defined as the proportion of CPS cases correctly identified by QUOCCAS; specificity is the proportion of non-CPS cases correctly identified.

    Measured: Baseline to study completion, up to 36 months

Secondary outcomes (3)
  1. Genetic Literacy Score of Caregivers

    Change in caregiver knowledge and understanding of genetics and cancer predisposition syndromes, measured with a validated genetic literacy questionnaire (Fitzgerald-Butt et al. 2016) and additional CPS-specific items. The genetic literacy score comprises 18 items with each correct item being attributed one point (higher scores from 0-18 indicating higher genetic literacy). The CPS-specific part comprises 10 items with each correctly answered item being attributed one point (higher scores from 0-10 indicating higher genetic literacy). Mean scores of each item will be compared between participants who received the Pre-Visit Preparation (PVP) brochure and those who did not.

    Measured: Baseline to study completion, up to 36 months

  2. Patient and Caregiver Satisfaction with Care and Information

    Satisfaction measured using the Picker Patient Experience Questionnaire (PPE-15), adapted for the study, focusing on clarity of information, involvement in decision-making, and overall satisfaction with care. Proportions of problematic items (with higher proportions indicating more problematic encounters and negative experience) will be compared between families receiving the PVP brochure and those not receiving it.

    Measured: Baseline to study completion, up to 36 months

  3. Feasibility of Implementing QUOCCAS Questionnaire for Identifying Cancer Predisposition Syndromes and the Pre-Visit Preparation (PVP) Brochure

    Feasibility will be evaluated through the proportion of eligible families who successfully complete the QUOCCAS questionnaire, average time to complete the questionnaire, and provider survey feedback on ease of use and workflow integration.

    Measured: At study completion, up to 36 months
