Abstract

Objective

This study aimed to review the scientific literature on the effects of cancer treatment-related oral complications on the quality of life and well-being of children surviving cancer. This study updates a previous review, from 2012, evaluating the oral health related quality of life and well-being of childhood cancer survivors and exploring the extent to which children’s perspectives are considered in research.

Introduction

According to the World Health Organization, in 2020 nearly 280 000 children and young adults around the world were diagnosed with cancer, of which approximately 110 000 died [1]. In Canada, an estimated 4,975 children were newly diagnosed with cancer between 2018 and 2023 [2]. Despite persistent and substantial disparities across cancer types and resource settings, advances in treatment modalities, such as chemotherapeutic agents, have contributed to a general worldwide decline in pediatric cancer mortality rates [3]. 

Materials and method

Protocol and registration

A protocol of this scoping review has been published (https://doi.org/10.1371/journal.pone.0290364) [24].

Study design

The scoping review followed the Joanna Briggs Institute Reviewer’s Manual to assure transparency, accuracy, and completeness [25] and the Arksey and O’Malley’s methodological framework of six stages for conducting a scoping review, with Levac et al’s additions to the framework [26,27].

Results

Our final sample was comprised of 79 articles (Fig 1). The Inter-rater reliability between two reviewers, using Cohen’s kappa coefficient was 0.79, which indicates substantial agreement between reviewers.

Discussion

This scoping review provides an updated synthesis of literature examining the impact of cancer treatment-related oral complications on the quality of life and well-being of childhood cancer survivors. In relation to the previous review by Noronha and Macdonald [13], our findings highlight notable changes in research approaches, particularly in the increased inclusion of patient-reported outcomes and the use of validated QoL and OHRQoL measurement tools.

Conclusion

In the last 13 years since the original review, the literature on the impact of cancer therapy-related oral complications on the quality of life and well-being of pediatric cancer survivors has evolved. A key development is the increased use of QoL and OHRQoL measures. Additionally, there has been a shift towards including children-reported symptoms rather than relying solely on parental or healthcare provider assessments.
