Following this puts new work involving it at the top of your briefing, with a note saying why it is there. Links are taken from the source record, never inferred.
International Journal of Clinical Oncology and Cancer Research
A single-centre retrospective descriptive study over 15 years with no comparator, control group, or analytical design; reports incidence and outcomes but cannot test causation or establish clinical efficacy.
Retrospective real-world database analysis of testing utilization and costs across nine cancer types; descriptive findings on patterns and cost variation, but without comparative efficacy, clinical outcome, or causal inference.
A narrative synthesis of epidemiological trends and clinical management implications for HCC in Europe, intended to inform practice and policy rather than report a primary research finding.
Large prospective multicenter registry study with rigorous cross-sectional design and complete clinicopathological data, providing population-level prevalence estimates and validated independent predictors of mismatch repair deficiency in an unselected colorectal cancer cohort.
A narrative review synthesizing case reports and pharmacovigilance signals to propose mechanisms linking ICI use to AA amyloidosis; the source explicitly states mechanisms are hypotheses rather than confirmed pathways and evidence remains scarce with causality unestablished.
A single case report documenting an unusual clinical trajectory; provides descriptive evidence of disease evolution but lacks comparative data, control group, or generalizable findings.
Multicenter retrospective cohort study with propensity score matching comparing 690 early-onset and 6,193 late-onset lung cancer patients, reporting clinically meaningful survival differences and tumor biology features across clearly defined groups.
Population-based prospective cohort with long-term follow-up (10 years) and hard clinical outcomes (prostate cancer-specific mortality, overall survival) across multiple treatment modalities, though observational design and residual confounding limit causal inference.
