Furthermore, functional experiments demonstrated that silencing CARD11 and GATA2 impairs HR repair efficiency and enhances the sensitivity of tumor cells to olaparib treatment. In summary, in the absence of mutations in the HR genes, the sensitivity of tumor cells to PARP inhibitors and platinum-based chemotherapy may be enhanced in a subset of breast cancer patients with LNGC somatic mutations.

The most frequent AEs with C + F were diarrhoea (60.6% vs 11.3% P + F) and hyperglycaemia (57.7% vs 17.7%); the most frequent grade ≥3 AEs were rash maculopapular (8.5% vs 0%), rash and diarrhoea (both 7.0% vs 0%); grade ≥3 hyperglycaemia was 1.4% vs 0%. AEs leading to C/F discontinuation were reported in 11.3% for C + F vs 3.2% for P + F. Conclusions Similar to the Global population, the benefit–risk profile of C + F in the Chinese cohort appears favourable; no new safety concerns with C + F were identified.

Conclusions The combination of RNA- and DNA-based NGS provides information about molecular alterations for the management of patients with CNS tumors. Those with actionable gene fusions or other alterations may benefit from target therapy, especially in the setting of limited choice of treatments.

"Burning Rock Biotech Limited...is pleased to announce that our flagship comprehensive genomic profiling (CGP) product, OncoScreen Plus, was featured in a phase 3 multi-regional clinical trial (MRCT), along with FoundationOneCDx, in support of advancement in breast cancer treatment...In the study, Burning Rock's flagship comprehensive genomic profiling (CGP) product, OncoScreen Plus, was used to determine activating mutations in PIK3CA and AKT1 and inactivating alterations in PTEN genes for patients enrolled in China."

Our study shows that NGS could efficiently facilitate the definitive diagnosis of ES and its mimics. We also revealed a diverse immune-genomic landscape of these SRCS, indicative of potential therapeutic opportunities targeting HRD and immune check-point in specific subtypes of these sarcoma entities.

The combination of RNA and DNA-based NGS techniques brings relevant information about tumor molecular alterations into the precision management of patients with bone and soft-tissue tumors. Those with tumors harboring targetable gene fusions and other alterations may benefit from target therapy, especially in the case of limited or exhausted standard therapy.

Further analysis showed that patients in GI-high group had higher tumor grade, aneuploidy and lower T cell infiltrations. Conclusions The one-stop method of GI index combined with POLE mutation offers more accurate and stable disease risk stratification and demonstrates the potential for guiding therapy for EC patients.
