Hum Pathol

November 2024

Institute of Pathology, Department of Laboratory Medicine and Pathology, Lausanne University Hospital and Lausanne University, Lausanne, Switzerland. Electronic address:

The analysis of circulating tumor DNA (ctDNA) in liquid biopsy specimens has an established role for the detection of predictive molecular alterations and acquired resistance mutations in several tumors. The low-invasiveness of this approach allows for repeated sampling and dynamic monitoring of disease evolution. Originating from the entire body tumor bulk, plasma-derived ctDNA reflects intra- and interlesional genetic heterogeneity.

Article Synopsis
  • Reciprocal translocation (RT) carriers have a higher risk of infertility, miscarriages, and children with health issues due to the production of unbalanced gametes.
  • Prenatal diagnosis (PND) and preimplantation genetic diagnosis (PGD) can help minimize these risks, but there are concerns about the effectiveness of sperm fluorescence in situ hybridization (spermFISH) as a diagnostic tool for RT carriers.
  • A study of 41 RT carriers indicated that acrocentric chromosomes lead to more unbalanced gametes, and the variability in balanced sperm rates suggests that using spermFISH routinely may not be beneficial for these patients.
