HRD has diverse manifestations in different cancers and even in different populations. We propose using the following definition: HRD is a phenotype that is characterized by the inability of a cell to effectively repair DNA double-strand breaks using the HRR pathway. Poly (ADP-ribose) polymerase (PARP) inhibitors and platinum-based chemotherapies have been found to be particularly effective in tumors that harbor deleterious germline or somatic mutations in the BRCA1 or BRCA2 genes, the products of which contribute to the conservative homologous recombination repair of DNA double-strand breaks. There is an urgent need to understand the clinical implications of HRD signatures. In these cancers, BRCA1 / 2 alterations and genomic scar signatures are useful indicators for assessing HRD. As shown in Table 2, the deficiency of homologous recombination can impede the process of DNA double-strand break repair, which commonly promote tumorigenesis (Fig. In addition to these case studies, the doctors talked about their methods of using CGP in their practice, their distinction between testing tissue versus liquid, the challenges of attracting talent to the lab, the business of .

Here, we investigate the prevalence of HRD and TMB in Chinese and Western cancer patients. This approach is based on the principle that the normal function of homologous recombination ensures the error-free repair of double-strand breaks; therefore, in its absence, specific DNA scars accumulate in the genome that are the resultants of the error-prone repair of double-strand DNA breaks that occur due to, for example, replication stress.
