Integrated Methylation and Copy Number Analysis for Noninvasive Bladder Cancer Detection in Urine
Beijert et al.
The finding, in our words
The authors developed an integrated sequencing workflow that simultaneously profiles copy number aberrations and a three-gene methylation panel from home-collected urine cell-free DNA, achieving high diagnostic accuracy for both primary and recurrent bladder cancer in a cohort of 89 participants, which supports the feasibility of decentralised cancer detection from self-collected urine samples.

This review summarises how emerging HPV detection methods including CRISPR/Cas systems, droplet digital PCR and isothermal amplification, combined with self-collected vaginal swabs and liquid biopsy from urine or blood, could improve screening acceptability and enable point-of-care testing compared with conventional approaches that require invasive sampling and centralised laboratory infrastructure.

Midstream urine self-collection demonstrated adequate sensitivity for Chlamydia trachomatis screening in asymptomatic patients, although it was less sensitive than vaginal swabs in women, and the study confirmed that nucleic acids in neat urine remain stable for up to seven days when stored at 4°C.

This study found strong agreement between self-collected urine samples tested with the INDICAID HPV assay and clinician-collected swabs tested with the BD Onclarity assay for detecting high-risk HPV. The results suggest that urine-based self-collection offers a reliable alternative for cervical cancer screening, potentially improving access for women who face barriers to standard care.

Salivary HPV DNA testing achieved 91.7% sensitivity and 100% specificity against oropharyngeal swab in patients with oral cavity cancer, demonstrating potential for non-invasive self-collection screening programmes and long-term monitoring of HPV-driven disease.
An eight-millilitre sample of first-morning urine self-collected without prostatic massage yields reproducible microbial profiles using PathoChip microarray. The workflow identified Streptococcaceae enrichment in higher-grade prostate cancer, supporting its potential for decentralised, non-invasive screening, though larger validation cohorts are needed.
