Understanding perceptions of tumor genomic profile testing in Black/African American cancer patients in a qualitative study: the role of medical mistrust, provider communication, and family support
CC Luck et al, J Comm Genetics, Feb 16, 2024

From the abstract: "Tumor genomic profiling (TGP) examines genes and somatic mutations specific to a patient’s tumor to identify targets for cancer treatments but can also uncover secondary hereditary (germline) mutations. Most patients are unprepared to make complex decisions related to this information. Black/African American (AA) cancer patients are especially at risk because of lower health literacy, higher levels of medical mistrust, and lower awareness and knowledge of genetic testing. But little is known about their TGP attitudes or preferences. "

Forget lung, breast or prostate cancer: why tumour naming needs to change The conventional way of classifying metastatic cancers according to their organ of origin is denying people access to drugs that could help them.
F Andre et al, Nature, January 31, 2024

From the article: " Over the past century, the two main approaches to treating people with cancer — surgery and radiation — have focused on where in the body the tumour is. This has led to medical oncologists and other health-care providers, regulatory agencies, insurance companies, drug firms — and patients — categorizing cancers according to the organ in which the tumour originated. Yet there is a growing disconnect between classifying cancers in this way and developments in precision oncology, which uses the molecular profiling of tumour and immune cells to guide therapies."

Landmark national study supports use of whole genome sequencing in standard cancer care
Genomics England, January 2023

From the website: "In the largest study of its kind, scientists today report how combining health data with whole genome sequence (WGS) data in patients with cancer can help doctors provide more tailored care for their patients. The research shows that linking WGS data to real-world clinical data can identify changes in cancer DNA that may be relevant for an individual patient’s care, for example by helping identify what treatment might work best for them based on their cancer.

Insights for precision oncology from the integration of genomic and clinical data of 13,880 tumors from the 100,000 Genomes Cancer Programme
A Sosinsky et al, Nature Medicine, January 11, 2024

From the abstract: "We analyzed WGS data from 13,880 solid tumors spanning 33 cancer types, integrating genomic data with real-world treatment and outcome data, within a secure Research Environment. Incidence of somatic mutations in genes recommended for standard-of-care testing varied across cancer types. For instance, in glioblastoma multiforme, small variants were present in 94% of cases and copy number aberrations in at least one gene in 58% of cases, while sarcoma demonstrated the highest occurrence of actionable structural variants (13%).
