Liquid biopsies and cancer omics.

Cell Death Discov 2020 Nov 26;6(1):131. Epub 2020 Nov 26.

Torvergata Oncoscience Research Centre of Excellence, TOR, Department of Experimental Medicine, University of Rome Tor Vergata, 00133, Rome, Italy.

The development of the sequencing technologies allowed the generation of huge amounts of molecular data from a single cancer specimen, allowing the clinical oncology to enter the era of the precision medicine. This massive amount of data is highlighting new details on cancer pathogenesis but still relies on tissue biopsies, which are unable to capture the dynamic nature of cancer through its evolution. This assumption led to the exploration of non-tissue sources of tumoral material opening the field of liquid biopsies. Read More

An innovative and user-friendly scoring system for standardised quantitative interpretation of the urine-based point-of-care strip test (POC-CCA) for the diagnosis of intestinal schistosomiasis: a proof-of-concept study.

Acta Trop 2019 Nov 16;199:105150. Epub 2019 Aug 16.

Department of Parasitology, Leiden University Medical Centre, Albinusdreef 2, 2333 ZA Leiden, the Netherlands. Electronic address:

The point-of-care strip assay for the detection of the schistosome Circulating Cathodic Antigen (POC-CCA) in urine has shown to be a user-friendly and sensitive alternative to stool microscopy for the diagnosis of Schistosoma mansoni infections. However, visual scoring of the test is by definition observer dependent and leads to discussion about the qualitative interpretation, in particular in low intensity infections when test lines tend to be weak. In order to standardise visual scoring, an innovative approach for semi-quantitative interpretation of the POC-CCA cassettes, called G-scores, was developed and evaluated. Read More

Refining Diagnosis of Infections: Antigen and Antibody Detection in Urine.

Front Immunol 2018 14;9:2635. Epub 2018 Nov 14.

Department of Cell and Chemical Biology, Leiden University Medical Center, Leiden, Netherlands.

Traditional microscopic examination of urine or stool for schistosome eggs lacks sensitivity compared to measurement of schistosome worm-derived circulating antigens in serum or urine. The ease and non-invasiveness of urine collection makes urine an ideal sample for schistosome antigen detection. In this study several user-friendly, lateral-flow (LF) based urine assays were evaluated against a composite reference that defined infection as detection of either eggs in urine or anodic antigen in serum.
