Urothelial carcinoma is the predominant cancer of the urinary tract but when divergent and subtype histology (non-urothelial) are identified at time of pathologic diagnosis, therapeutic and diagnostic challenges transpire. To this end, pathologic review to confirm any non-urothelial histology is key since these subtypes can often be overlooked. Few prospective trials are dedicated to understanding these non-urothelial histologic types; however, current, and past trials did allow patients with these non-urothelial histologic types to enroll, and inferences can be made about treatment efficacy and survival.

A phase I trial of the novel combination of the ataxia telangiectasia and Rad3-related inhibitor berzosertib plus the antibody-drug conjugate sacituzumab govitecan in patients with heavily pretreatment tumors demonstrated some antitumor activity and no dose-limiting toxicities. This represents a new treatment paradigm that will be further explored in a phase II setting. See related article by Abel et al.

Combination therapies with immune checkpoint blockers have shown improvements in overall response rate, progression free survival, and overall survival over monotherapy with sunitinib in intermediate and poor risk subgroups. Identification of best upfront therapy may be guided by future clinical trials utilizing adaptive strategies, triplet therapy, or novel biomarkers.

Treatment advances in kidney cancer continually evolve. The focus of treatment options continues with oral vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors (TKIs) or intravenous immune checkpoint inhibitors (ICIs). Multiple trials exploring the role of adjuvant treatment after cytoreductive nephrectomy in high-risk clear cell renal cell carcinoma are currently ongoing.

Cyclic AMP (cAMP) and Ca(2+) are two ubiquitous second messengers in transduction pathways downstream of receptors for hormones, neurotransmitters and local signals. The availability of fluorescent Ca(2+) reporter dyes that are easily introduced into cells and tissues has facilitated analysis of the dynamics and spatial patterns for Ca(2+) signaling pathways. A similar dissection of the role of cAMP has lagged because indicator dyes do not exist.
