Value of a 21-gene expression assay on core biopsy to predict neoadjuvant chemotherapy response in breast cancer: systematic review and meta-analysis.
Boland M R et al. The British journal of surgery 2021 108(1) 24-31

This systematic review aimed to determine whether the 21-gene expression assay performed on core biopsy at diagnosis predicted pathological complete response (pCR) to neoadjuvant chemotherapy. The study was performed according to PRISMA guidelines. Relevant databases were searched to identify studies assessing the value of the 21-gene expression assay recurrence score in predicting response to neoadjuvant chemotherapy in patients with breast cancer.

BRAF-mutant ctDNA predicts outcomes.
Sidaway Peter et al. Nature reviews. Clinical oncology 2021 3

Circulating tumor DNA (ctDNA) has the potential to improve patient management in a range of disease settings; however, data from large cohorts of patients are currently limited. Now, an analysis of samples from two clinical trials provides further evidence that BRAF mutations present in ctDNA can be used to predict clinical outcome.

A Proclamation on National Colorectal Cancer Awareness Month, 2021
The White House, March 1, 2021

People with increased risk for developing the disease include certain racial and ethnic minority populations, as well as individuals with inflammatory bowel disease, a family history of colorectal cancer, or other risk factors such as tobacco use.

Gene Sequencing for Pathogenic Variants Among Adults With Breast and Ovarian Cancer in the Caribbean
SHL George et al, JAMA Network Open, March 1, 2021

This genetic association study included 1018 adult women and men with breast and ovarian cancer, of which 144 individuals had a pathogenic variant in a moderate- to high-risk gene. This finding was consistent with high rates of premenopausal breast cancer in Black women with Caribbean ancestry.
