PURPOSE: While retroperitoneal lymph node dissection (RPLND) is traditionally reserved for nonseminomatous germ cell tumors, recent efforts to reduce long-term toxicities of radiation and chemotherapy have turned attention to its application for testicular seminomas. Currently, RPLND is reserved for the post-chemotherapy for stage II testicular seminomas; we aimed to describe current utilization of RPNLD for testicular seminomas by stage and implications for survival. METHODS: A national sample of men diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminoma (1988-2013) was evaluated from SEER Program registries...

PURPOSE: Adjuvant therapies for non-metastatic renal cell carcinoma (nmRCC) are being tested to improve outcomes in patients with high-risk (hR) nmRCC. The objective of the current study is to test the ability of three hR features to identify patients who are at the highest risk of cancer-specific mortality (CSM) after partial or radical nephrectomy. METHODS: Within the Surveillance Epidemiology and End Results (SEER) database (1988-2013), we identified 23,632 nm "clear cell" RCC partial or radical nephrectomy patients with hR features: Fuhrman grade (FG) 3 or 4 or pathological classifications T3a or T3b or lymph node invasion (LNI), or combination of these...

PURPOSE: Hyperoxaluria-induced calcium oxalate crystallisation is associated with the generation of reactive oxygen species (ROS) via mitochondria and NADPH oxidase. Endoplasmic reticulum (ER) has emerged as an organelle which could influence mitochondrial functioning and ROS generation. Plugging an upstream pathway of mitochondrial and NADPH oxidase-induced ROS generation may have better prophylaxis. Therefore, we propose to investigate the linkage of hyperoxaluria-induced ROS generation with ER stress by inhibiting the later with 4-Phenylbutyric acid (4-PBA)...
