Consolidation immunotherapy following concurrent chemoradiotherapy in a patient with sinonasal NUT carcinoma: a case report.

Background: Nuclear protein in testis (NUT) cancers, also known as midline cancers, tends to occur in organs near the midline, such as the nasal sinuses and mediastinum. NUT carcinoma is very rare and has a poor prognosis.

Case Description: We report the case of a 44-year-old female patient with sinonasal NUT carcinoma who presented with a soft tissue mass in the left frontal sinus, ethmoid sinus, and left nasal cavity on computed tomography; the tumor was poorly demarcated from the left rectus medialis.

Direct comparison of an ultrasensitive real-time PCR assay with droplet digital PCR for the detection of hotspot mutations in primary tumors, plasma cell-free DNA and paired CTC-derived gDNAs.

Introduction: Detection of mutations in primary tumors and liquid biopsy samples is of increasing importance for treatment decisions and therapy resistance in many types of cancer. The aim of the present study was to directly compare the efficacy of a relatively inexpensive ultrasensitive real-time PCR with the well-established and highly sensitive technology of ddPCR for the detection of the three most common hotspot mutations of , in exons 9 and 20, that are all of clinical importance in various types of cancer.

Patients And Methods: We analyzed 42 gDNAs from primary tumors (FFPEs), 29 plasma-cfDNA samples, and 29 paired CTC-derived gDNAs, all from patients with ER+ metastatic breast cancer, and plasma from 10 healthy donors.

Pathological features of the differentiation landscape in esophageal squamous cell cancer and their correlations with prognosis.

Background: For esophageal squamous cell carcinoma (ESCC), universally accepted pathological criteria for classification by differentiation degree are lacking. Tumor budding, single-cell invasion, and nuclear grade, recognized as prognostic factors in other carcinomas, have rarely been investigated for their correlation with differentiation and prognosis in ESCC. This study aims to determine if pathological findings can predict differentiation degree and prognosis in ESCC.

Background: Globally, colorectal cancer (CRC) is among the most prevalent malignant tumors. It is characterized by unlimited proliferation, invasion, and metastasis. MicroRNA-126 (miR-126) has been shown in many studies to play a significant role in CRC, but data regarding its role in CRC Egyptian patients are limited.

IGF2BP2 Shapes the Tumor Microenvironment by Regulating Monocyte and Macrophage Recruitment in Bladder Cancer.

Background: Immunotherapy has shown promise for bladder cancer (BC) treatment but is effective only in a subset of patients. Understanding the tumor microenvironment (TME) and its regulators, such as the expression of N6-methyladenosine (m6A) regulators, may improve therapeutic outcomes. This study focuses on the role of IGF2BP2, an m6A reader, in modulating the BC TME.

RNA-binding protein quaking: a multifunctional regulator in tumour progression.

Background: Quaking (QKI) is a member of the signal transduction and activators of RNA (STAR) family, performing a crucial multifunctional regulatory role in alternative splicing, mRNA precursor processing, mRNA transport and localization, mRNA stabilization, and translation during tumour progression. Abnormal QKI expression or fusion mutations lead to aberrant RNA and protein expression, thereby promoting tumour progression. However, in many types of tumour, QKI played a role as tumour suppressor, the regulatory role of QKI in tumour progression remains ambiguous.

Inhibitory Effect of PRMT5/MTA Inhibitor on MTAP-Deficient Glioma May Be Influenced by Surrounding Normal Cells.

Background: Methylthioadenosine phosphorylase (MTAP) and protein arginine methyltransferase 5 (PRMT5) are considered to be a synthetic lethal pair of targets, due to the fact that deletion of MTAP leads to massive production of methylthioadenosine (MTA) decreasing the activity of PRMT5. In vitro and in vivo experiments have demonstrated that MRTX1719, a small molecule that selectively binds PRMT5/MTA complex, significantly inhibits the proliferation of MTAP-deficient tumors and has a weak toxic effect on normal cells. However, it has been reported that MTAP-deleted tumors did not significantly accumulate MTA in vivo due to metabolism of MTA by MTAP-expressing stroma, which might lead to a diminished anti-cancer effect of MRTX1719.

Stemness regulation in prostate cancer: prostate cancer stem cells and targeted therapy.

Background: Increasing evidence indicates that cancer stem cells (CSCs) and cancer stem-like cells form a special subpopulation of cells that are ubiquitous in tumors. These cells exhibit similar characteristics to those of normal stem cells in tissues; moreover, they are capable of self-renewal and differentiation, as well as high tumorigenicity and drug resistance. In prostate cancer (PCa), it is difficult to kill these cells using androgen signaling inhibitors and chemotherapy drugs.

Methods: The study included 25 patients with advanced or recurrent endometrial cancer who had received LEN/PEM between August 2018 and March 2024.

Mutational Landscape of Bone Marrow CD19 and CD138 Cells in Waldenström Macroglobulinemia (WM) and IgM Monoclonal Gammopathy of Undetermined Significance (IgM MGUS).

Background: Despite recurrent and activating mutations, including MYD88, CXCR4, ARID1A, KMT2D, and CD79B were identified, the genetic basis for Waldenström's Macroglobulinemia (WM) and the risk of progression of IgM MGUS to WM remain to be fully elucidated.

Methods: We investigated the mutation status of WM (n = 8), sWM (n = 7), and IgM MGUS (n = 5) patients, by performing high-throughput targeted AmpliSeq NGS on 117 target genes. Specifically, we analyzed the CD19+ cells from 15 WM/sWM patients and five IgM MGUS patients.

Risk Stratification of Miscellaneous Uterine Mesenchymal Neoplasms: The Role of Morphology, Immunohistochemistry, and Molecular Testing.

Uterine mesenchymal tumors are a diverse group of tumors that can display a broad range of morphologic, immunohistochemical, and molecular profiles and are associated with varied clinical behaviors. In recent years, they have increasingly been classified by their underlying molecular alterations, leading to a more precise separation of diagnostic entities. As their diagnostic criteria have been refined, so too have the features that can be used to predict clinical outcomes.

Risk Stratification of Uterine Smooth Muscle Tumors: The Role of Morphology, Immunohistochemistry, and Molecular Testing.

Uterine smooth muscle neoplasms are a biologically and clinically heterogeneous group of tumors. Morphology is the cornerstone of pathologic diagnosis of these tumors, and most are readily classified as benign or malignant on the basis of routine histologic examination. However, rare subsets-including intravenous leiomyomatosis, benign metastasizing leiomyoma, and disseminated peritoneal leiomyomatosis-have a capacity for extrauterine spread despite benign cytomorphology.

GOLPH3-STIP1 Complex Activates STAT3 Through Exosome Secretion to Induce Colon Cancer Metastasis.

With a high mortality rate, colon cancer (CC) is the third most common malignant tumor worldwide. The primary causes are thought to be the high invasiveness and migration of CC cells. The functions of Golgi phosphoprotein 3 (GOLPH3), stress-induced phosphoprotein 1 (STIP1), and the signal transducer and activator of transcription 3 (STAT3) signaling pathway in the invasion and migration of CC cells were examined in this study.

Differential expression of metabolic enzymes in testicular germ cell tumors: The impact of glycolytic metabolism in embryonal carcinoma histotype.

Background: Testicular germ cell tumors are the most common solid malignancies in young men, with increasing incidence worldwide. Broadly classified into seminomas and non-seminomas, they exhibit distinct biological behaviors and responses to treatment. Although metabolic reprogramming is an acknowledged cancer hallmark, metabolic pathways in testicular germ cell tumors remain poorly understood.

Tumour purity assessment with deep learning in colorectal cancer and impact on molecular analysis.

Tumour content plays a pivotal role in directing the bioinformatic analysis of molecular profiles such as copy number variation (CNV). In clinical application, tumour purity estimation (TPE) is achieved either through visual pathological review [conventional pathology (CP)] or the deconvolution of molecular data. While CP provides a direct measurement, it demonstrates modest reproducibility and lacks standardisation.
