Objective:
To evaluate the risk factors of postoperative upgrade to pT3a of cT1 renal cell carcinoma, and to establish a nomogram prediction model to improve the ability of predicting locally advanced renal cell carcinoma and provide a reference for clinical surgical decision-making.
Methods:
Clinical data of 1 376 patients with cT1 (diameter ≤ 7 cm) renal tumor hospitalized for surgery from January 2010 to December 2016 were retrospectively analyzed. There were 979 males and 397 females, with the mean age of (57.65±10.92) years. The mean body mass index (BMI) was (25.47±3.27) kg/m2 and the average tumor size was (4.02±1.52) cm. There were 711 tumors on the left and 665 on the right. There were 363 cases with clinical symptoms, 567 patients with smoking history , 732 cases with history of chronic disease. There were 289 cases with tumor necrosis, 636 cases with tumor protrusion, 822 cases with irregular tumor , and 738 cases with renal sinus compression. Partial nephrectomy and radical nephrectomy were performed in 396 cases and 980 cases respectively. Mann-whitney

Primary ureteral plasmacytoid carcinomas is a rare tumor with high grade and poor diagnosis. Pathological and immunohistochemical staining play an extremely key role in diagnosis since there is no specific clinical and radiological evidence. The surgical removement is the first line treatment. Herein, we report a case of ureteral plasmacytoid carcinoma that was well controlled with multimodal therapy.
