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.

Parkinson’s disease is one of the most insidious neurodegenerative diseases in developed countries. Today, human pluripotent stem cells are produced from embryonic or adult cells, multiplied, differentiated into neural cell lines and ultimately transplanted into disease animal models or patients. Nowadays, DOPAminergic neurons derived from human pluripotent stem cells and human parthenogenetic cells are being clinically tested in China and Australia, respectively. More importantly, good manufacturing practices have been developed and the neurons obtained have been successfully tested in nonhuman primates by teams in Europe, USA and Japan. However, there is a need for translational clinical studies with small molecules tested in vitro, as well as testing of the the efficacy of additional therapies.

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.

Although a recognized condition, growing teratoma syndrome (GTS) has no guidelines for management, and patients diagnosed with the condition are managed empirically by the most appropriate teams. We report a case of GTS in a 33-year-old patient who was initially treated with unilateral salpingo-oophorectomy and subsequent chemotherapy for a germ cell ovarian tumor. GTS was subsequently diagnosed with massive pelvic and upper abdominal masses as well as lung tumors. We also conducted a literature review on cases of GTS presenting with large tumors. Based on this, we suggest a management plan to guide the care of women with GTS. The condition is best managed in a multidisciplinary team involving the relevant surgeons, including gynecologist, abdominal and thoracic surgeons.
