Universal tumor screening for lynch syndrome on colorectal cancer biopsies impacts surgical treatment decisions.

Fam Cancer 2022 Jun 23. Epub 2022 Jun 23.

Department of Pathology, The Ohio State University Wexner Medical Center, Optometry Clinic and Health Science Faculty Office Building, 1664 Neil Avenue, Suite 6100, Columbus, OH, 43210, USA.

Universal tumor screening (UTS) for Lynch syndrome (LS) on colorectal cancer (CRC) can be performed on biopsies or resection specimens. The advantage of biopsies is the chance to provide preoperative genetic counseling/testing (GC/T) so patients diagnosed with LS can make informed decisions regarding resection extent. We evaluated utilization of UTS on biopsies, percentage of patients with deficient mismatch repair (dMMR) who underwent GC/T preoperatively, and whether surgical/treatment decisions were impacted.

Vaccines for immunoprevention of DNA mismatch repair deficient cancers.

J Immunother Cancer 2022 Jun;10(6)

University Hospital Heidelberg, Institute of Pathology, Department of Applied Tumor Biology, Heidelberg, Germany.

The development of cancer vaccines to induce tumor-antigen specific immune responses was sparked by the identification of antigens specific to or overexpressed in cancer cells. However, weak immunogenicity and the mutational heterogeneity in many cancers have dampened cancer vaccine successes. With increasing information about mutational landscapes of cancers, mutational neoantigens can be predicted computationally to elicit strong immune responses by CD8 +cytotoxic T cells as major mediators of anticancer immune response.

Colon Tumors in Enterotoxigenic Bacteroides fragilis (ETBF)-Colonized Mice Do Not Display a Unique Mutational Signature but Instead Possess Host-Dependent Alterations in the APC Gene.

Microbiol Spectr 2022 May 19:e0105522. Epub 2022 May 19.

Department of Medicine, Johns Hopkins University School of Medicinegrid.471401.7, Baltimore, Maryland, USA.

Enterotoxigenic Bacteroides fragilis (ETBF) is consistently found at higher frequency in individuals with sporadic and hereditary colorectal cancer (CRC) and induces tumorigenesis in several mouse models of CRC. However, whether specific mutations induced by ETBF lead to colon tumor formation has not been investigated. To determine if ETBF-induced mutations impact the gene, and other tumor suppressors or proto-oncogenes, we performed whole-exome sequencing and whole-genome sequencing on tumors isolated after ETBF and sham colonization of and VC mice, as well as whole-genome sequencing of organoids cocultured with ETBF.
