Rare presentation and unconventional treatment of Rosai-Dorfman disease. (PubMed, BMJ Case Rep)
We present a case of a man in his late 50s with RDD who experienced worsening cytopenias, including severe neutropenia and respiratory distress, despite an initial positive response to steroids, rituximab and lenalidomide. Sirolimus was initiated and led to complete radiological remission of the disease. This case adds strength to the growing evidence supporting the efficacy of sirolimus in refractory RDD cases.

KRAS mutations in pulmonary adenocarcinomas (ECP 2024)
KRAS is an attractive therapeutic strategy due to its high prevalence and its role in initiating and sustaining tumour growth. Approval of KRAS G12C inhibitors in locally advanced or metastatic NSCLC has brought hope to many patients. Studies show that non G12C KRAS mutation are found in 53% of adenocarcinomas.

Monoallelic KRAS (G13C) mutation triggers dysregulated expansion in induced pluripotent stem cell-derived hematopoietic progenitor cells. (PubMed, Stem Cell Res Ther)
Our findings indicate that a monoallelic oncogenic KRAS can confer dysregulated expansion characteristics to non-transformed HPCs, which may constitute a pathological condition in RALD hematopoiesis. The use of iPSC-based screening platforms will lead to discovering treatments that enable selective inhibition of RAS-mutated HPC clones.

Prognostic value of specific KRAS mutations in patients with colorectal peritoneal metastases. (PubMed, ESMO Open)
In patients with CRC PM, different KRAS mutation subgroups can be determined according to specific codon substitution, with some mutations (KRASMUT1) that could have a similar prognosis to wild-type patients. These findings should be further investigated in larger series.

Top-Down Proteomic Assay to Evaluate KRAS4B-Compound Engagement. (PubMed, Anal Chem)
We present two applications to demonstrate the capabilities of our assay: maleimide-biotin labeling of a KRAS4BG12D cysteine mutant panel and treatment of three KRAS4B proteins (WT, G12C, and G13C) with small molecule compounds. Our results show the time- or concentration-dependence of KRAS4B-compound engagement in context of the intact protein molecule while directly mapping the compound binding site.

BRAF Mutation Heterogeneity Detected Using Circulating Tumor DNA Sequencing in Synchronous Colon Cancer: A Case Report. (PubMed, Cancer Diagn Progn)
Next, we performed next-generation sequencing on circulating tumor DNA from the patient's plasma (Foundation One Liquid CDx), which revealed the V600E mutation of BRAF, suggesting that there was genetic heterogeneity among the synchronized primary lesions, one of which was responsible for the chemo-refractory rapid-growing liver metastases. Genetic profiling with liquid biopsy at the time of recurrence and metastasis may be useful in patients with multiple synchronous cancers because there is less heterogeneity between primary and metastatic sites.

A Case of Rosai‑Dorfman Disease, Associated With KRAS 13C, POLE, and NDE1 Mutations, Masquerading as Chronic Myelomonocytic Leukemia: Complex Management Paradigm (SOHO 2023)
A 57-year-old man with RDD developed worsening cytopenias and respiratory distress after his initial response to rituximab, steroids, and lenalidomide. NGS is likely to be helpful for the work-up and management of RDD. We found potential novel therapeutic targets in RDD, such as KRAS G13C and POLE mutations.

Prevalence of KRAS Subtype Alterations in Non-Small Cell Lung Cancer (NSCLC) with Brain Metastases (IASLC-WCLC 2023)
This study details the most prevalent KRAS alterations and co-mutations among KRASalt NSCLC. KRAS p.G12C was the most frequently observed alteration and co-mutations were found in TP53, LRP1B, STK11, KEAP1, and CDKN2A. Our findings have therapeutic implications as co-alterations with STK11/KEAP1 are associated with worse outcomes.

Molecular Characterization of Non-small Cell Lung Cancer in People Living with HIV or Solid Organ Transplants (IASLC-WCLC 2023)
The identification of targetable genomic alterations in tumors from individuals living with HIV and solid organ transplant recipients underscores the importance of comprehensive molecular testing in these patient populations. While important markers of immunotherapy response (PD-L1, TMB) were similar, different immune characteristics were identified. Further research is necessary to fully understand the molecular profiles of lung cancer in individuals with HIV and solid organ transplant.

Distant Metastasis Pattern and Baseline Clinicopathological Features from a Real-World KRAS G12C Mutant Cohort of Advanced NSCLC Patients (IASLC-WCLC 2023)
In our observational study the distribution of KRAS mutational status, its mutual exclusion with other concomitant driver mutations, and the strong association with smoking were consistent with data from literature. The G12C subgroup showed a different metastasis pattern with greater number of metastasis sites and higher incidence of brain metastases at the time of diagnosis compared to non-G12C patients. Despite the limited sample size, these results suggest that KRAS mutant patients represent a highly heterogeneous population and underline the need of better characterization of these patients to tailor treatment strategies.

Prevalence and patterns of mutations in RAS/RAF/MEK/ERK/MAPK signaling pathway in colorectal cancer in North Africa. (PubMed, BMC Cancer)
KRAS mutated CRC patients in North Africa have been identified with incidence closer to the European figures. Beside established anti-CRC treatment, better understanding of the causality of CRC can be established by combining epidemiology and genetic/epigenetic on CRC etiology. This approach may be able to significantly reduce the burden of CRC in North Africa.

Clinical characteristic and outcomes of KRAS G13 mutant non-small cell lung cancers. (ASCO 2022)
Pts with KRAS G13C/D had poor survival and response to therapies in comparison with G12C and other non-G12C KRAS mts, particularly with IO-containing regimens. Recently (Judd et al, MCT-21-0201), STK11 and KEAP1 were reported to be frequently co-mutated with KRAS G13* (37.3 and 12.6%) compared to other KRAS mts, and this genotypemay confer primary resistance to IO. We hypothesize that the poor outcomes and immune resistance in G13* mut may be secondary to higher prevalence of STK11 and KEAP1 co-mutations.

Novel approaches for the development of direct KRAS inhibitors: structural insights and drug design. (PubMed, Expert Opin Drug Discov)
Despite the efforts of more than four decades, not many KRAS inhibitors have been successful in obtaining clinical approval, except the very recent FDA approval for sotorasib...In view of this aspect, specific attention is required to target all other mutations as well. Accordingly, for the development of KRAS targeted therapies, the design of small molecule inhibitors that can inhibit KRAS signaling and as well as target inhibition of other signaling pathways like RAS-SOS and RAS-PI3K has to be explored extensively.

[VIRTUAL] Voruciclib, a CDK9 inhibitor, downregulates MYC and inhibits proliferation of KRAS mutant cancers in preclinical models (AACR 2021)
Collectively, these data demonstrate that voruciclib inhibition of CDK9 leads to reduced phosphorylation of MYC on Ser 62 followed by a decrease in total MYC protein in MIA PACA-2 cells and inhibition of growth in multiple KRAS mutant cancer cell lines in vivo and in vitro. This suggests that voruciclib could be an attractive therapeutic option for cancers driven by KRAS-MYC.
