Lfng-expressing centroacinar cell is a unique cell-of-origin for p53 deficient pancreatic cancer. (PubMed, Oncogene)
Finally, high LFNG expression is associated with high grade and poor survival in human patients. Taken together, Lfng marks a centroacinar subpopulation that is uniquely susceptible to oncogenic transformation when p53 is lost, and Lfng functions as an oncogene in all three lineages of the exocrine pancreas.

A Rare Case of Primary Hepatic Undifferentiated Pleomorphic Sarcoma: Exploring Cancer-related Gene Mutations. (PubMed, Intern Med)
Despite initiating hepatic arterial infusion chemotherapy, the tumor continued to grow, and the patient's poor performance status complicated the transition to a phase I KRAS mutation drug trial, leading to death eight months after the symptom onset. A timely genetic mutation analysis may facilitate effective treatment transitions in hepatic UPS despite the lack of established treatments.

Combined KRAS and TP53 mutation in patients with colorectal cancer enhance chemoresistance to promote postoperative recurrence and metastasis. (PubMed, BMC Cancer)
Furthermore, advanced-stage patients with concurrent KRAS and TP53 mutations are susceptible to developing cancer-associated cachexia due to chemotherapy resistance or forced cessation of treatment. Our findings underscore the urgent need for the development of innovative and novel chemotherapeutic strategies to effectively manage colorectal cancer patients harboring combined KRAS and TP53 mutations.

LLS 2024 ELN-REFINED RISK STRATIFICATION IN OLDER ADULTS WITH NEWLY DIAGNOSED ACUTE MYELOID LEUKEMIA TREATED WITH LOW-INTENSITY THERAPY (EHA 2024)
Among patients ≥60 yrs with ND AML given LIT, the current 2022 ELN risk system classifies most (79%)patients as adverse risk and does not reliably distinguish favorable from intermediate-risk, highlighting thelimitations of the model in this patient population. We propose a refined LLS classification using a "mutationscore" incorporating IDH2, MLL2, KRAS and TP53 mutations for those previously assigned ELN 2022 adverserisk, as well as redefining the definition of LLS-favorable risk.

TGFβ-induced long non-coding RNA LINC00313 activates Wnt signaling and promotes cholangiocarcinoma. (PubMed, EMBO Rep)
We propose a model whereby TGFβ induces LINC00313 in order to regulate the expression of hallmark Wnt pathway genes, in co-operation with SWI/SNF. By modulating key genes of the Wnt pathway, LINC00313 fine-tunes Wnt/TCF/LEF-dependent transcriptional responses and promotes cholangiocarcinogenesis.

Correlation analysis of clinical, pathological, imaging and genetic features of ground-glass nodule featured lung adenocarcinomas between high-risk and non-high-risk individuals. (PubMed, Eur J Med Res)
GGN-featured lung adenocarcinoma is dominated by non-high-risk female patients. Shorter preoperative follow-up in the non-high-risk group and no statistical difference in GGN detection way suggests the existing screening criteria for high-risk population may not suit GGN-featured lung cancer. In addition, the incidences of KRAS and TP53 mutations are higher in the high-risk group.

Local Control Following Stereotactic Body Radiation Therapy for Liver Oligometastases: Lessons from a Quarter Century. (PubMed, Curr Oncol)
However, several predictive factors play a crucial role in the efficacy of stereotactic body radiation therapy, such as the number and size (volume) of metastatic liver lesions, the primary tumor site (histology), molecular biomarkers (e.g., KRAS and TP53 mutation), the use of systemic therapy prior to SBRT, the radiation dose, and the use of advanced technology and organ motion management during SBRT. These prognostic factors need to be considered when clinical trials are designed to evaluate the efficacy of SBRT for liver metastases.

TFEB activation in mediastinal lymph nodes: a potential modulator of immune response in NSCLC (SITC 2023)
Notably, overexpressing TFEB in CD11c+ dendritic cells augmented tumor-specific CD4 T-cell responses, yet reduced CD8 T-cell activities, suggesting a potential shift towards a tolerogenic immune environment in NSCLC. Conclusions Conclusively, our insights into TFEB’s function in NSCLC highlight the complex relationship between tissue-specific elements and tumor immunogenicity, offering avenues for refining immunotherapeutic strategies.

Pancreatic ductal adenocarcinoma with a high expression of alcohol dehydrogenase 1B is associated with less aggressive features and a favorable prognosis. (PubMed, Am J Cancer Res)
PDAC patients with a high ADH1B expression had better disease-specific survival (DSS) and overall survival (OS) and ADH1B was an independent prognostic biomarker for both DSS (HR = 0.89, 95% CI = 0.80-0.99, P = 0.045) and OS (HR = 0.90, 95% CI = 0.82-0.99, P = 0.044) in multivariate analysis. In conclusion, PDAC with high ADH1B expression had less cell proliferation and malignant features, along with higher immune cell infiltration, and had a better prognosis.

Deciphering SWI/SNF complexes role in lung cancer using the Tuba-seq tool in a mouse model of lung adenocarcinoma (EACR 2023)
Barcoding sequencing will allow the determination of tumor number and size and, therefore, the assessment of this SWI/SNF subunits oncogenic potential. Further transcriptional experiments will allow us to identify the molecular pathways altered by SWI/SNF deficiency in our model.ConclusionWe have successfully generated all necessary tools to perform Tuba-seq experiments to study at the molecular level the role of SWI/SNF alteration in a mouse model of LUAD.

The genomic and transcriptomic landscapes of chemotherapy naïve vs post-chemotherapy germ cell tumors. (ASCO 2023)
Background: Cisplatin resistance occurs in up to 30% of patients with advanced germ cell tumors (GCTs)... This study provides evidence that chemo naïve GCTs with mutations in TP53, KRAS, KIT or MDM2 CNA have higher expression of genes associated with resistance to platinum-based chemotherapy. These findings contribute to a better understanding of the molecular characteristics of GCTs and may inform prognosis and treatment.

Molecular correlates of male germ cell tumors with overgrowth of components resembling somatic malignancies. (PubMed, Mod Pathol)
In conclusion, GCT with SM are characterized by widespread aneuploidy, a distinct epigenetic signature and the presence of mutations that are otherwise rare in testicular GCT without SM. The similarity of the mutational and DNA methylation profiles of different histologic types of SM suggests that the identification of SM components could be more important than their precise histologic subclassification, pending confirmation by further studies.

Distinct mechanisms of innate and adaptive immune regulation underlie poor oncologic outcomes associated with KRAS-TP53 co-alteration in pancreatic cancer. (PubMed, Oncogene)
Immune subtyping of KRAS-TP53 co-altered PDAC reveals conflation of intratumor heterogeneity with progenitor-like stemness properties. Coalescing these distinct molecular characteristics into a KRAS-TP53 co-altered "immunoregulatory program" predicts chemoresistance in metastatic PDAC patients enrolled in the COMPASS trial, as well as worse overall survival.

A primary DICER1-sarcoma with KRAS and TP53 mutations in a child with suspected ECCL. (PubMed, Brain Tumor Pathol)
Compared to the previously reported cases, our unique case of primary DICER1-sarcoma also demonstrated neurofilament and chromogranin positivity, and genomic instability with loss of chromosome 4p, 4q, 8p, 11p, and 19p, as well as gains in chromosome 7p, 9p, 9q, 13q, and 15q on copy variant analysis. The detailed sequencing and methylation information discovered in this unique case of DICER1-sarcoma will hopefully help further our understanding of this rare and emerging entity.

Molecular Characterization of Pancreatic Ductal Adenocarcinoma Using a Next-Generation Sequencing Custom-Designed Multigene Panel. (PubMed, Diagnostics (Basel))
Intriguingly, KRAS wild-type cases had a better short-term prognosis despite the lymph node status. In conclusion, our work highlights that the combination of KRAS mutation with the age of the patient and the lymph node status may help in predicting the outcome in PDAC patients.

Colorectal Cancer Is Associated with the Presence of Cancer Driver Mutations in Normal Colon. (PubMed, Cancer Res)
These results indicate that somatic evolution contributes to clonal expansions in the normal colon and that this process is enhanced in individuals with cancer, particularly in those with early-onset colorectal cancer. This work suggests prevalent somatic evolution in the normal colon of patients with colorectal cancer, highlighting the potential of using ultrasensitive gene sequencing to predict disease risk.
