Epigenome-wide analysis of methylation changes in the sequence of gallstone disease, dysplasia, and gallbladder cancer. (PubMed, Hepatology)
Our results indicate that GBC carcinogenesis comprises three main methylation stages: early (gallstone disease and low-grade dysplasia), intermediate (high-grade dysplasia), and late (GBC). The identified gradual changes in methylation and CNVs may help to enhance our understanding of the mechanisms underlying this aggressive disease and eventually lead to improved treatment and early diagnosis of GBC.

Activation of the RAS pathway through uncommon BRAF mutations in mucinous pancreatic cysts without KRAS mutation. (PubMed, Mod Pathol)
Multiple KRAS mutations correlated with multifocal cysts demonstrated by radiology. In IPMNs that lacked KRAS mutations, the concurring BRAF mutations with GNAS mutations supports an alternate mechanism of activation in the Ras pathway.

Concurrent TP53 and CDKN2A Gene Aberrations in Newly Diagnosed Mantle Cell Lymphoma Correlate with Chemoresistance and Call for Innovative Upfront Therapy. (PubMed, Cancers (Basel))
Concurrent aberration of TP53 and CDKN2A is a new, simple, and relevant index of chemoresistance in MCL. Patients with concurrent aberration of TP53 and CDKN2A should be offered innovative anti-lymphoma therapy and upfront consolidation with allogeneic stem cell transplantation.

A genomic biomarker-based model for cancer risk stratification of non-dysplastic Barrett's esophagus patients after extended follow up; results from Dutch surveillance cohorts. (PubMed, PLoS One)
The positive and negative predictive values were 0.13 (95% CI 0.09 to 0.19) and 0.97 (95% CI 0.93 to 0.99). We propose the implementation of the model to identify non-dysplastic Barrett's patients, who are required to remain in surveillance programs with 3-yearly surveillance intervals from those that can benefit from less frequent or no surveillance.

From Genes to -Omics: The Evolving Molecular Landscape of Malignant Peripheral Nerve Sheath Tumor. (PubMed, Genes (Basel))
However, broader genomic studies have also identified recurrent but less prevalent genetic variants in human MPNST that also contribute to the molecular landscape of MPNST and may inform further research. Future studies to further define the molecular landscape of human MPNST should focus on collaborative efforts across multiple institutions in order to maximize information gathered from large numbers of well-annotated MPNST patient samples, both in the NF1 and the sporadic MPNST populations.

Analysis of targeted somatic mutations in pleomorphic carcinoma of the lung using next-generation sequencing technique. (PubMed, Thorac Cancer)
Significant findings of the study This study demonstrates that mutations in the TP53 gene are frequently found and co-mutations are sometimes found in pleomorphic carcinoma of the lung using genomic profiling analysis. What this study adds Our results will help to analogize the genetic characteristics and potential target of molecular-targeted agents of pleomorphic carcinoma of the lung.

Pancreatic ductal adenocarcinomas from Mexican patients present a distinct genomic mutational pattern. (PubMed, Mol Biol Rep)
In addition, we discovered several recurrent putative copy number aberrations in SKP2, BRAF, CSSF1R, FOXE1, JAK2 and MET genes and in genes previously reported as putative drivers in PDAC, including KRAS, SF3B1, BRAF, MYC and MET. Although a larger cohort is needed to validate these findings, our results could be pointing toward potential differences in contributing factors for PDAC in Latin-American populations.

Biomarker-driven phase 2 umbrella trial study for patients with recurrent small cell lung cancer failing platinum-based chemotherapy. (PubMed, Cancer)
To the best of the authors' knowledge, the current study is the first biomarker-driven umbrella study conducted in patients with recurrent SCLC. Although the current study demonstrated the limited clinical efficacy of monotherapy, novel biomarker approaches using other cell cycle inhibitor(s) or combinations warrant further investigation.

Melanoma with in-frame deletion of MAP2K1: a distinct molecular subtype of cutaneous melanoma mutually exclusive from BRAF, NRAS, and NF1 mutations. (PubMed, Mod Pathol)
In-frame deletions in MAP2K1, previously shown in experimental models to be strongly MAPK-activating, characterized a significant subset of triple wild-type melanoma (2.0%), suggesting a primary oncogenic role for these mutations. Comprehensive genomic profiling of melanomas enables detection of this alteration, which may have implications for potential therapeutic options.

Simple mucinous cysts of the pancreas have heterogeneous somatic mutations. (PubMed, Hum Pathol)
Four cases (31%) had no mutations detected. These findings place the majority of simple mucinous cysts of the pancreas in the spectrum of early, low grade mucinous neoplasia, albeit with an different spectrum of genomic alterations than PanIN and intraductal papillary mucinous neoplasm.

[VIRTUAL] POLO: Homologous recombination repair gene mutations (HRRm) in metastatic pancreatic cancer (mPaC) tumors (AACR-I 2020)
In the Phase III POLO trial (NCT02184195) maintenance olaparib conferred a progression-free survival benefit over placebo in pts with a germline (g) BRCAm and mPaC...Prevalence of mutations in non-HRR genes (CDKN2A, SMAD4, KRAS, TP53) in POLO was consistent with that seen in other pancreatic cancer cohorts.In summary, based on the subgroup of pts with analyzed tumor tissue, the genetic profile of the screened POLO population is reflective of that seen in the overall pancreatic cancer population. ~8% of pts had tumors harboring a BRCAm, with mutations in BRCA2 more prevalent than BRCA1; ~7% of pts had tumors harboring a non-BRCA HRRm, most commonly in ATM (~5%).

Burkitt lymphoma: bridging the gap between advances in molecular biology and therapy. (PubMed, Leuk Lymphoma)
The lower-intensity, dose-adjusted EPOCH plus rituximab (DA-EPOCH-R) regimen constitutes a major advance allowing for treatment of older and HIV-positive patients but needs augmentation to better address the central nervous system involvement. Furthermore, DA-EPOCH-R provides a platform for the study of targeted or immunotherapeutic approaches while de-escalating cytotoxic agents and their associated adverse effects. In this review we discuss the epidemiology and molecular genetics of BL, first-line treatment considerations, and potential novel treatment strategies.
