cfDNA-Based NGS IG Analysis in Lymphoma

Circulating cell-free DNA (cfDNA) is fragmented extracellular DNA, which is released from apoptotic and necrotic cells in small fragments of <200 bp [1]. cfDNA is typically isolated from the blood stream; however, it is also possible to detect cfDNA in other biological fluids such as urine or cerebrospinal fluid [2, 3,…

h2o AutoML vs h2o XGBoost – model metrics

The problem here is that you are comparing training metrics for XGBoost to CV metrics for AutoML models. The code you posted for the manual XGBoost models provides training metrics. Instead, you will need to grab the CV metrics if you want to make a fair comparison to the performance…

Novel Test Distinguishes Benign From Malignant Lesions in NF1

A novel liquid biopsy test has been shown to distinguish between patients with neurofibromatosis type 1 (NF1) who have benign plexiform neurofibroma (PN) precursor lesions from patients who have malignant peripheral nerve sheath tumors (MPNST), say authors of a multi-institutional cross-sectional study. “Transformation from PN to MPNST is challenging to…

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…

Dissecting Cancer with Single-cell DNA Sequencing & Multi-omics | Learning Center

CANCER & SINGLE-CELL ANALYSIS The heterogeneity and dynamism of cancer present formidable challenges to understanding and treating the disease. As discussed in the last section, tumor evolution often leads to considerable genetic variation across clones. But the complexity of tumors does not stop at the level of DNA. Intratumoral phenotypic…
