Samples from patients with AML show high concordance in detection of mutations by NGS at local institutions vs central laboratories.

Next-generation sequencing (NGS) to identify pathogenic mutations is an integral part of acute myeloid leukemia (AML) therapeutic decision-making. The concordance in identifying pathogenic mutations among different NGS platforms at different diagnostic laboratories has been studied in solid tumors but not in myeloid malignancies to date. To determine this interlaboratory concordance, we collected a total of 194 AML bone marrow or peripheral blood samples from newly diagnosed patients with AML enrolled in the Beat AML Master Trial (BAMT) at 2 academic institutions.

The Effect of Electrical Stimulation on Nerve Regeneration Following Peripheral Nerve Injury.

Peripheral nerve injuries (PNI) are common and often result in lifelong disability. The peripheral nervous system has an inherent ability to regenerate following injury, yet complete functional recovery is rare. Despite advances in the diagnosis and repair of PNIs, many patients suffer from chronic pain, and sensory and motor dysfunction.

Cessation of Routine Jejunostomy Tube Placement at Time of Minimally Invasive Ivor Lewis Esophagectomy and Impact on Body Mass Index.

Jejunostomy tubes are frequently placed at time of esophagectomy. The purpose of this study is to evaluate cessation of routine j-tube placement on postoperative body mass index (BMI), return to the emergency room, and time until adjuvant therapy. We performed a retrospective review of an institutional database for consecutive patients undergoing minimally invasive Ivor Lewis Esophagectomy from 2014-2021 (after January 2019, routine j-tube placement was abandoned).

Induction within or after 12 hours of ≥36 weeks' prelabor rupture of membranes: a systematic review and meta-analysis.

Objective: This study aimed to evaluate the incidence of chorioamnionitis in women with singleton gestations with ≥36 weeks' prelabor rupture of membranes induced with oxytocin within or after 12 hours of prelabor rupture of membranes.

Data Sources: The search was conducted using MEDLINE, Web of Sciences, Scopus, ClinicalTrial.gov, OVID, and Cochrane Library as electronic databases from their inception to May 2020.

Comprehensive genomic sequencing of paired ovarian cancers reveals discordance in genes that determine clinical trial eligibility.

Objective: We analyzed comprehensive genomic sequencing results from paired ovarian cancer samples to identify changes in mutational events over time.

Methods: DNA from paired FFPE tumor samples from 50 ovarian cancer patients in the Clearity Foundation Data Repository was analyzed for genomic mutations (GM), copy number alterations (CNA), microsatellite status (MS), tumor mutation burden (TMB), and loss of heterozygosity (LOH) by hybrid-capture, next-generation sequencing of up to 315 genes. Genomic profiles were compared between samples from the same patient.

A Pan-Cancer Landscape Analysis Reveals a Subset of Endometrial Stromal and Pediatric Tumors Defined by Internal Tandem Duplications of BCOR.

Background: The Polycomb Repressive Complex 1 (PRC1) regulates epigenetic silencing and is manifestly linked to rare cancer types. The X-linked BCOR gene (BCL-6 Corepressor) is a member of the PRC1 complex and potentiates transcriptional repression through BCL6 binding of PRC1. Accumulating evidence suggests that internal tandem duplications (ITD) of BCOR are oncogenic drivers in a subset of pediatric sarcomas and rare adult tumors.
