Unmet supportive care needs of patients with rare cancer: A systematic review

Objective Patients with rare cancers may experience different unmet needs than those with common cancer. The objective of this systematic review was to (1) investigate unmet supportive care needs of rare cancer patients throughout the disease trajectory and (2) identify predictive factors for these unmet needs. Methods PubMed, PsycINFO and CINAHL were searched for publications (January 2011 to March 2021) focusing on unmet needs of patients with rare cancer. Two reviewers independently selected studies, extracted data and performed quality assessment. Findings were synthesised. Results The search yielded 4,598 articles, of which 59 articles met eligibility criteria and 57 were of medium or high quality. Rare cancer patients most frequently reported unmet needs in the healthcare system and information domain (up to 95%), followed by the psychological domain (up to 93%) and the physical and daily living domain (up to 80%). Unmet needs were mainly reported in the posttreatment phase. The most frequently identified predictors were higher anxiety, younger age and higher neuroticism. Conclusion Patients with rare cancer have unmet needs throughout their disease trajectory. Supportive care needs of rare cancer patients should be addressed individually, depending on the rare cancer subdomain and phase of disease and from diagnosis onwards.

Automated summary

Patients with rare cancers often report unmet supportive care needs in healthcare system and information domain (up to 95%), psychological domain (up to 93%) and physical and daily living domain (up to 80%), mainly in the posttreatment phase. The most frequently identified predictors were higher anxiety, younger age and higher neuroticism.
