BRAF (B-raf proto-oncogene)

Genomic profiling of sarcomas offers valuable insights into their molecular drivers and can support personalized therapeutic approaches. Further research is needed to validate these findings and optimize treatment strategies for sarcoma patients.

Primary colonic SRCC is a rare malignant tumor with atypical clinical symptoms, and timely identification and intervention are crucial for improving the prognosis.

BRAF mutation analysis can be performed on fixed fine needle aspiration cytology specimens. Although the frequency of the mutation is higher in specimens with higher Bethesda category scores, it could support clinical decision-making in thyroid nodules with intermediate Bethesda category scores.

We then applied KDCA to The Cancer Genome Atlas thyroid data set and found several differentially co-expressed pathways by age of diagnosis and BRAF mutation status that were undetected by the eigengene method. Collectively, our results demonstrate that KDCA is a powerful testing framework that expands DCA applications in expression studies.

The responsiveness of gastrointestinal stromal tumors to imatinib requires validation via molecular testing. Patients diagnosed with pancreatic cancer may see enhanced survival rates by targeted therapy addressing microsatellite instability and BRCA mutations. In bile duct malignancies, especially intrahepatic cholangiocarcinoma of the small duct variant, the analysis of IDH1 mutations and FGFR2 fusions presents new treatment prospects.

Triplet induction chemotherapy is a treatment of choice in selected patients with SMRC, allowing to adapt the therapeutic strategy to the response and invasiveness of the various sites.

Real-world data suggest that adjuvant TT may be associated with better RFS and DMFS in stage III BRAF V600-mutated melanoma compared to ICI.

The P-selectin-targeted nanoparticles showed enhanced accumulation in 3D spheroids and tissues of P-selectin-expressing BRAF-mutated melanomas and BRCA-mutated breast cancers, resulting in superior in vivo efficacy and safety. This nanoplatform could advance the codelivery of a plethora of anticancer drug combinations to various P-selectin-expressing tumors.

The lack of association between molecular alteration status and recurrence risk prevailed after multivariable adjustment for tumor stage and perioperative treatment (P=0.82 for KRAS G12C mutation and P=0.43 for any other molecular alteration). NSCLC patients with resected tumors that harbor molecular alterations have the same recurrence risk as patients with tumors without molecular alterations if treated with surgery plus chemotherapy when indicated.

This is a case showing improvement of a craniopharyngioma after treatment with BRAF and MEK inhibitor combinations. The role of BRAF and MEK inhibitor combinations continues to evolve in this space.

This study is the largest clinical study to date utilizing the TSO 500. It provides an opportunity to further characterize the landscape of NSCLC using this newer technology and show its clinical utility in detecting known and novel facets of NSCLC to inform treatment decision-making.

This study underscores the potential of dRT as a feasible strategy for deferring systemic therapy escalation in patients with oligometastatic and oligoprogressive metastatic thyroid cancer, demonstrating that sequential dRT courses impart excellent local control and are safe to deliver repeatedly for multiple distant sites. Further studies are warranted to validate these findings and elucidate the full benefit of dRT as part of a multidisciplinary approach for metastatic thyroid cancer.

We also discuss the clinical relevance of biomarkers, emphasizing their alignment with the National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology (NCCN Guidelines®) as well as ancillary tests such as BRAF VE1 immunohistochemistry to detect BRAF V600E mutation and molecular techniques such as real-time polymerase chain reaction, matrix-assisted laser desorption ionization-time of flight mass spectrometry and next-generation sequencing. Our proposed standardized minimum criteria for reflex testing prioritize melanomas with Breslow thickness >4 mm or disseminated disease, who will most benefit from enhanced delivery of biomarkers and expedited access to targeted therapies while attempting to balance cost-effectiveness and utilization of public healthcare resources with patient outcomes.

Approximately 2% of all CRC cases in this study were CLDN18.2 positive and had unfavorable features (e.g., mucinous or poorly differentiated adenocarcinoma, T3-4 disease, lymphatic invasion, BRAF V600E mutation) and deficient MMR status. CLDN18.2 positivity did not have a significant impact on RFS or OS.

Gliomas are tumors arising in the central nervous system, frequently associated with Class I mutations and BRAF fusions. Further research into resistance mechanisms and long-term effects is necessary to optimize treatment strategies. Other therapies, such as everolimus and Selumetinib, also show potential and warrant further investigation.

Bethesda III-VI thyroid nodules with isolated RAS mutations have a low rate of aggressive histopathologic features and are unlikely to recur. Thyroid lobectomy may be sufficient treatment for these tumors.

In gallbladder and biliary tract cancers, we are mainly looking for IDH1 and IDH2 mutations, FGFR2 gene fusions and mutations, HER2 amplifications or mutations, as well as mutations of BRAF or BRCA1/2. All results should be discussed within the molecular tumor board.

While our study showed no significant difference in three-year RFS, adjuvant chemotherapy intensification with HAI-FUDR is feasible and may offer early benefits in RFS and long-term OS. Nonetheless, a larger sample size is needed for validation and identifying which patient subgroup might benefit from this regimen.

Since BRAF activation occurs in BRAF fusion gene tumors and BRAF mutations, they could share a similar mechanism in tumorigenesis. This case suggests the further expansion of kinase-related spindle cell tumors.

Although current first- and second-line therapies stratify for KRAS/NRAS/BRAF mutations, microsatellite instability, tumour location and co-morbidities, the therapeutic mainstay for the first- and second-line treatment of the majority of patients consists of 5-fluorouracil (5-FU)-based chemo-immunotherapy. By exchanging the chemotherapeutic combination partner from oxaliplatin to irinotecan or vice versa, plus the additive anti-epidermal growth factor receptor/anti-vascular endothelial growth factor antibody, the negative factor of non-response to first-line therapy could not be overcome by second-line treatment in this study population. These findings must be confirmed in larger studies, but indicate the need for novel treatment options, especially for patients not responding to first-line 5-FU-based chemo-immunotherapy.

LUADMuc represents a distinct LUAD subpopulation with unique clinicopathologic, genomic, immunophenotypic, and transcriptional features, achieving worse outcomes to standard immunotherapy-based treatments.

Considering the occurrence of several actionable alterations including a TPM4:NTRK1 fusion reported herein, these results support the use of next-generation sequencing (NGS) including RNA analysis for fusion detection to identify such alterations in patients with MPTs. These findings highlight the importance of comprehensive NGS in MPT research to uncover potential targeted treatment options for these patients.

BRAF class 3 mutations in NSCLC may identify a novel targetable population sensitive to EGFR-TKIs.

Importantly, genetic and pharmacological targeting of PI3Kβ phenocopied PREX2 deficiency, sensitizing model systems to therapy. These data reveal a druggable PREX2/RAC1/PI3Kβ signaling axis in BRAF-mutant melanoma that could be exploited clinically.

In this limited case series, two patients were dead at the last follow-up. Whether these findings are consistent within this patient population remains to be addressed as more patient series are published.
