Factors of emotional distress in lymphoma: A systematic review.

OBJECTIVE

Distress is prevalent among lymphoma patients/survivors. Current processes of distress identification rely on self-reporting by patients/survivors, which may be limited by their willingness to report symptoms. To help identify patients/survivors at greater risk, this systematic review aims to comprehensively review factors that may contribute to distress in lymphoma patients/survivors.

METHODS

PubMed was systematically searched for peer-reviewed primary articles (1997-2022) consisting of standardised keywords "lymphoma" and "distress." Information from 41 articles was integrated via narrative synthesis.

RESULTS

Consistent risk factors of distress include younger age, relapsed disease, and greater comorbidities and symptom burden. Active treatment and the transition from treatment to post-treatment could be challenging phases. Adequate social support, adaptive adjustment to cancer, engaging in work and healthcare professionals' support may mitigate distress. There is some evidence that older age may be associated with greater depression and life changes/experiences may shape how individuals cope with lymphoma. Gender and marital status were not robust predictors of distress. Other clinical, psychological and socioeconomic factors are understudied or have mixed findings.

CONCLUSIONS

While several factors of distress align with that of other cancers, more research is needed to identify significant factors of distress in lymphoma patients/survivors. The identified factors may support clinicians in identifying distressed lymphoma patients/survivors and providing interventions where necessary. The review also highlights avenues for future research and a need to routinely collect data on distress and its factors in registries.
