Renal cell carcinoma (RCC) with rhabdoid differentiation is thought to portend a poor prognosis, similar to RCC with sarcomatoid differentiation. Mayo Clinic researchers reviewed a large series of patients with grade 4 RCC to determine the differential effects of rhabdoid and sarcomatoid differentiation on patient outcome.

Measurement of sex steroids, particularly testosterone and estradiol, is important for diagnosis or management of a host of conditions. Mayo Clinic researchers summarize why and how liquid chromatography tandem mass spectrometry (LC-MS/MS) is increasingly replacing other methodologies for measurement of testosterone and estradiol.

Detection of Histoplasma capsulatum urine antigen (UAg) is among the most sensitive and rapid means to diagnose histoplasmosis. In a recent study published in the Journal of Clinical Microbiology, Mayo Clinic researchers analyzed the IMMY analyte specific reagents for detection of Histoplasma galactomannan.

LDL cholesterol (LDL-C)3, an important modifiable risk factor for atherosclerotic cardiovascular disease, is primarily calculated via the Friedewald equation. However, a newly derived equation for LDL-C estimation was recently published that addressed limitations in the commonly used Friedewald LDL-C calculation method. Mayo Clinic researchers completed a study to evaluate the performance of a novel method to classify patients with superior concordance to measured LDL-C compared to the Friedewald method.

Mayo Clinic researchers completed a study in Modern Pathology to examine ERBB2 amplification and protein expression in micropapillary urothelial carcinoma and stage-matched typical urothelial carcinoma treated by radical cystectomy to assess the frequency of amplification and protein expression, and to determine the association with cancer-specific survival. Read this post to learn more.

Flow cytometry immunophenotyping has been suggested as an adjunctive technique in the evaluation of myeloid malignancies, especially in the myelodysplastic syndromes. Its use, however, has been limited due to complexity and cost restraints. A recent study by Mayo Clinic was completed to attempt a simpler approach to flow cytometry immunophenotyping in myeloid neoplasms.
