Predictive accuracy of risk prediction models for recurrence, metastasis and survival for early-stage cutaneous melanoma: a systematic review.

OBJECTIVES: To identify prognostic models for melanoma survival, recurrence and metastasis among American Joint Committee on Cancer stage I and II patients postsurgery; and evaluate model performance, including overall survival (OS) prediction. DESIGN: Systematic review and narrative synthesis. DATA SOURCES: Searched MEDLINE, Embase, CINAHL, Cochrane Library, Science Citation Index and grey literature sources including cancer and guideline websites from 2000 to September 2021. ELIGIBILITY CRITERIA: Included studies on risk prediction models for stage I and II melanoma in adults ≥18 years. Outcomes included OS, recurrence, metastases and model performance. No language or country of publication restrictions were applied. DATA EXTRACTION AND SYNTHESIS: Two pairs of reviewers independently screened studies, extracted data and assessed the risk of bias using the CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies checklist and the Prediction study Risk of Bias Assessment Tool. Heterogeneous predictors prevented statistical synthesis. RESULTS: From 28 967 records, 15 studies reporting 20 models were included; 8 (stage I), 2 (stage II), 7 (stages I-II) and 7 (stages not reported), but were clearly applicable to early stages. Clinicopathological predictors per model ranged from 3-10. The most common were: ulceration, Breslow thickness/depth, sociodemographic status and site. Where reported, discriminatory values were ≥0.7. Calibration measures showed good matches between predicted and observed rates. None of the studies assessed clinical usefulness of the models. Risk of bias was high in eight models, unclear in nine and low in three. Seven models were internally and externally cross-validated, six models were externally validated and eight models were internally validated. CONCLUSIONS: All models are effective in their predictive performance, however the low quality of the evidence raises concern as to whether current follow-up recommendations following surgical treatment is adequate. Future models should incorporate biomarkers for improved accuracy. PROSPERO REGISTRATION NUMBER: CRD42018086784.

Unrepresented, unheard and discriminated against: A qualitative exploration of relatives' and professionals' views of palliative care experiences of people of African and Caribbean descent during the COVID-19 pandemic.

BACKGROUND: People of African and Caribbean descent experienced disproportionately high mortality from COVID-19 and have poor access to palliative care. AIM: To explore palliative care experiences of people of African and Caribbean descent during and immediately prior to the pandemic. DESIGN: Qualitative interview study with thematic analysis. Refinement of themes/recommendations in consultation with an expert patient and public advisory group. SETTING/PARTICIPANTS: Twenty-six bereaved relatives and 13 health/social care professionals (cared for people of African and Caribbean descent) from throughout England, recruited using social media, community networks and direct advertising to over 150 organisations. RESULTS: Three themes were identified: Representation: Participants did not see themselves reflected in the palliative care services and did not expect their needs to be understood. Mistrust of the healthcare system and perceptions of racism were common and led to anticipation of inequitable care. Personalisation: Relatives and professionals reported a lack of cultural and religious sensitivity in healthcare. Assumptions were made based on ethnicity, and services not offered to all. Awareness and education: Professionals felt they lacked the knowledge to provide care to diverse communities, but were reluctant to ask, due to fear of making mistakes. Inequitable access to services was exacerbated by, but not unique to, the pandemic. Participants recommended raising awareness of palliative services, building professional competence in culturally-sensitive care, and greater ethnic diversity within services. CONCLUSIONS: Person-centred, culturally-competent palliative care is not the norm for people of African and Caribbean descent. Expectations of inequitable care are widespread. Sustained action on multiple fronts is needed.
