# Assessing the impact of timely diagnosis on psychological outcomes and quality of life for cancer patients: A scoping review

## TL;DR

This paper reviews how timely cancer diagnosis affects patients' mental health and quality of life, finding mixed evidence due to inconsistent study methods.

## Contribution

The study provides a scoping review highlighting the need for more consistent and high-quality research on timely cancer diagnosis and its psychological effects.

## Key findings

- Timely diagnosis is linked to better psychological outcomes and quality of life in cancer patients.
- Qualitative studies show an incidental relationship but do not focus on timely diagnosis.
- Definitions and measures of timely diagnosis vary widely across studies.

## Abstract

We explored the literature on timely cancer diagnosis and its significance on psychological outcomes or quality of life in cancer patients.

A scoping review to map existing literature in this area, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

Six studies were identified. Four studies used cross-sectional surveys, and one each used qualitative and mixed-method designs. Quantitative evidence suggests that timely diagnosis was associated with better psychological outcomes and quality of life. Qualitative and mixed-method evidence found an incidental relationship, but it was not a focus of the studies. There were varied definitions of timely diagnosis, and a diverse range of measures were used to identify outcomes. No study satisfied all quality appraisal criteria, with key dates in the diagnostic journey being the least reported (0/6 studies).

Preliminary evidence indicates that timely diagnosis may be associated with variations in psychological outcomes and quality of life in patients with cancer; however, methodological heterogeneity restricts the generalisability of the findings. More high-quality longitudinal quantitative and qualitative research is needed to explore the direction of the association and lived experience during the adjustment process.
