简要总结
The goal of the overall CASUS project is to develop the first fully molecular integrated cervical cancer screening approach, based on first-void urine as an easily accessible and non-invasive source of biomarkers. In contrast to current screening modalities, the CASUS approach will identify women with clinically relevant disease in need of treatment using only a single sample that can be collected at home (one-step triage).
详细描述
CASUS work package 1 (WP1): To accommodate for the detection of biomarkers in first-void urine, a next-generation first-void urine collection device is necessary, which includes internal process control, novel collector tubes for collection of smaller urine volumes, and integration of a non-toxic nucleic acid preservative. Hereto, new generations of the Colli-Pee® (Novosanis) first-void urine collector allowing collection of smaller volumes (Colli-Pee Small Volumes 4 and 10 mL) next to the 'standard' Colli-Pee FV5000 (20 mL) first-void urine collector will be developed and validated. The optimal urine volume needed for detection of host and viral biomarkers, as well as optimization of the nucleic acid preservative solution by introduction of a sample/extraction validation control (non-human DNA internal control (DNA IC)) will be evaluated by measuring the concentration of human DNA, HPV DNA, and the DNA IC in all first-void urine samples using different DNA extraction protocols.
