Leiomyosarcoma of the stomach is a very rare malignancy that was not distinguished from the more frequent gastrointestinal stromal tumors until early 2000s. Here we report on a case of a metastatic disease that developed in a 47-year-old man 2 years after he was diagnosed with the primary tumor and treated with curative surgical excision and adjuvant doxorubicin. The primary and metastatic lesions were positive for smooth muscle markers α-smooth muscle actin and h-caldesmon and negative for CD117, DOG-1 and S100 by immunohistochemistry. Metastatic disease progressed on additional monotherapy with doxorubicin and docetaxel-gemcitabine combination, and stable disease was achieved upon treatment with pazopanib. Patient is surviving 35 months since diagnosis of the primary tumor and 11 months since diagnosis of metastatic disease.

The 2018 FARA Biomarker Meeting highlighted the current state of development of biomarkers for Friedreich’s ataxia. A mass spectroscopy assay to sensitively measure mature frataxin (reduction of which is the root cause of disease) is being developed. Biomarkers to monitor neurological disease progression include imaging, electrophysiological measures and measures of nerve function, which may be measured either in serum and/or through imaging-based technologies. Potential pharmacodynamic biomarkers include metabolic and protein biomarkers and markers of nerve damage. Cardiac imaging and serum biomarkers may reflect cardiac disease progression. Considerable progress has been made in the development of biomarkers for various contexts of use, but further work is needed in terms of larger longitudinal multisite studies, and identification of novel biomarkers for additional use cases.

Expression of PD-L1 in the tumor is associated with more favorable responses to anti-PD-1 therapy in multiple cancers. However, obtaining tumor biopsies for PD-L1 interrogation is an invasive procedure and challenging to assess repeatedly as the disease progresses.

Dr. Pascale Richetta is Executive Vice President and Head of the Bone Patient Value Unit at UCB (Brussels, Belgium). She joined UCB in 2016 following over 20 years' experience in the pharma and biotech industry. After completing her MD at the University of Poitiers (France), she spent time as vice president at Abbvie/Abbott and has also held positions at GlaxoSmithKline, Ipsen and Servier. Through the course of her career she acquired impressive commercial experience managing both traditional pharmaceuticals and complex biologics and her knowledge of markets around the world is key to helping UCB prepare for future product launches.

Acinetobacter species have emerged as one of the most clinically important pathogens. The phenotypic techniques which are currently available are insufficient in accurately identifying and differentiating the closely related and clinically important Acinetobacter species. Here, we discuss the advantages and limitations of the conventional phenotypic methods, automated identification systems, molecular methods and MALDI-TOF in the precise identification and differentiation of Acinetobacter species. More specifically, several species of this genus are increasingly reported to be of high clinical importance. Molecular characterization such as of blaOXA-51-like PCR together with rpoB sequencing has high discriminatory power over the conventional methods for Acinetobacter species identification, especially within the Acinetobacter calcoaceticus-Acinetobacter baumannii complex.
