A hypoxia-related signature in lung squamous cell carcinoma

Introduction Lung cancer is the major leading cause of tumour-related deaths throughout the world, while lung squamous cell carcinoma (LUSC) as the second most common histological type of lung cancer.1 Each year, almost 1.8 million people are diagnosed with lung cancer worldwide and 400,000 of these die from LUSC.2,3 Due to…

Anaplastic Large Cell Lymphoma Presenting as Ulcerative Facial Mass: A Case Report – FullText – Case Reports in Oncology 2022, Vol. 15, No. 1

Anaplastic large cell lymphoma (ALCL) is a rare form of non-Hodgkin lymphoma (NHL) that can be aggressive with rapid speed, thus mandating a timely diagnosis to optimize treatment and deter progression. NHL classically presents with lymphadenopathy and constitutional symptoms. However, ALCL can present with nonspecific cutaneous manifestations with minimal or…

Alectinib Monotherapy in Isolated Central Nervous System Relapse of ALK-Positive Anaplastic Large Cell Lymphoma

Anaplastic lymphoma kinase-positive anaplastic large cell lymphoma (ALK-positive ALCL) is an aggressive form of peripheral T cell lymphoma (PTCL), harbouring an underlying pathogenic ALK fusion gene that produces a constitutively activated tyrosine kinase. The ALK tyrosine kinase provides a targeted treatment option in the form of ALK inhibitors. ALK-positive ALCL…

Characterization of Blood- Based Molecular Profiling in Pancreatic Adenocarcinoma

Introduction Most cases of pancreatic adenocarcinoma (PDAC) are diagnosed in the metastatic or locally advanced stage. It is the fourth leading cause of cancer death in the United States,1,2 with a 5-year overall survival (OS) around 10% in this country2 despite years of research and therapeutic development. For those patients…

Liquid Biopsy Noninferior to Tissue-Based Genotyping in Management of Advanced NSCLC

Cell-free circulating tumor DNA (cfDNA)–based tumor genotyping was found to be noninferior to standard-of-care tissue-based genotyping for detection of guideline-recommended biomarkers and therapeutic outcomes in patients with advanced nonsquamous non–small cell lung cancer (NSCLC). Cell-free circulating tumor DNA (cfDNA)–based tumor genotyping is noninferior to tissue-based genotyping for detection of guideline-recommended…

The Current Molecular Treatment Landscape of Advanced Colorectal Cancer and Need for the COLOMATE Platform

Next-Generation Sequencing Utilizing Tumor Tissue and/or Blood The identification of actionable genomic alterations in tumors such as mCRC was once performed by Sanger DNA sequencing of tumor DNA that was extracted from fixed paraffin-embedded tumor tissue, but this has now been replaced by next-generation sequencing (NGS), which allows for larger-scale…

High tumor mutation burden and DNA repair gene mutations

Introduction Anaplastic lymphoma kinase (ALK)‑fusion genes represent a small but important part of oncogenic driver mutations in NSCLC, accounting for approximately 3%‑7% of all cases worldwide.1,2 Small molecule tyrosine kinase inhibitors (TKIs) are the standard therapy for ALK-rearranged NSCLC. Crizotinib, a first-generation TKI, is the most widely used targeted drug…

Oncogene Concatenated Enriched Amplicon Nanopore Sequencing for rapid, accurate, and affordable somatic mutation detection | Genome Biology

Stochastic Amplicon Ligation. DNA samples for oncology sequencing are typically extracted from FFPE tissues and can have average lengths of less than 500 nt due to accumulated chemical damage [18]. We developed the Stochastic Amplicon Ligation (SAL) method to enzymatically concatenate many short DNA molecules together to utilize the long-read…

Defects in 8-oxo-guanine repair pathway cause high frequency of C > A substitutions in neuroblastoma

Significance The collection of large amounts of whole-genome sequencing data allowed for identification of mutational signatures, which are characteristic combinations of substitutions in the context of neighboring bases. The clinical significance of these mutational signatures is still largely unknown. In neuroblastoma, we showed that high levels of cytosine > adenine…

Nuclear protein in testis carcinoma

Introduction Nuclear protein in testis (NUT) carcinoma (NC) is defined by the rearrangement of the chromosomal region 15q14 harboring the NUTM1 gene. As a clinically aggressive neoplasm with poor differentiation, NC was previously believed to occur primarily in children and young adolescents. However, with an increasing number of reports, middle-aged…
