Clinical characteristics, risk factors, and outcomes after adjuvant radiotherapy for patients with thymoma in the United States: analysis of the Surveillance, Epidemiology, and End Results (SEER) Registry (1988–2013)
<p><b>Purpose:</b> The surgery with adjuvant radiation for the treatment of thymoma is still debated. The aim of this study was to examine the efficacy of postoperative radiotherapy (PORT) in a population-based registry of patients with thymoma.</p> <p><b>Materials and methods:</b> We conducted a retrospective analysis of the Surveillance, Epidemiology, and End Results database to compare the outcomes of patients with thymoma who received surgery with or without PORT.</p> <p><b>Results:</b> Among the 2234 patients of this study, the surgery with PORT group had a longer mean overall survival (OS) and cancer-specific survival (CSS) than did the surgery without PORT group (OS: 172.3 vs. 155.3 months, <i>p</i> = .005; CSS: 247.3 vs. 241.8 months, <i>p</i> = .04). PORT significantly improved OS and CSS of patients with stage III/IV disease, but decreased CSS for those with stage I/IIA disease. Although the surgery with PORT group had a higher rate of secondary cancers, the between-group difference in the disease-free interval was not significant.</p> <p><b>Conclusions:</b> PORT provides a significant benefit for patients with thymoma, particularly those with advanced disease. However, it also increases the risk of a second malignancy. We suggest that treatment guidelines should adopt a more positive stance on the use of PORT.</p

Design of Potent and Orally Active GPR119 Agonists for the Treatment of Type II Diabetes
We report herein the design and synthesis
of a series of potent
and selective GPR119 agonists. Our objective was to develop a GPR119
agonist with properties that were suitable for fixed-dose combination
with a DPP4 inhibitor. Starting from a phenoxy analogue (<b>1</b>), medicinal chemistry efforts directed toward reducing half-life
and increasing solubility led to the synthesis of a series of benzyloxy
analogues. Compound <b>28</b> was chosen for further profiling
because of its favorable physicochemical properties and excellent
GPR119 potency across species. This compound exhibited a clean off-target
profile in counterscreens and good <i>in vivo</i> efficacy
in mouse oGTT
Discovery of a Potent and Selective ROMK Inhibitor with Pharmacokinetic Properties Suitable for Preclinical Evaluation
A new subseries of ROMK inhibitors
exemplified by <b>28</b> has been developed from the initial
screening hit <b>1</b>. The excellent selectivity for ROMK inhibition
over related ion channels and pharmacokinetic properties across preclinical
species support further preclinical evaluation of <b>28</b> as
a new mechanism diuretic. Robust pharmacodynamic effects in both SD
rats and dogs have been demonstrated
