Introduction The effectiveness and safety of immune checkpoint inhibitor (ICI) monotherapy in advanced upper tract urothelial carcinoma (UTUC) is less reported. Methods In total, 106 consecutive advanced UTUC patients receiving ICI monotherapy were collected from nine high volume centers. Clinical outcomes were analyzed according to multiple parameters (e.g., treatment line, metastatic sites). Objective response rate (ORR), overall survival (OS) and progression‐free survival (PFS) were captured after ICI initiation. Results With a median follow‐up of 12.0 months, 25 patients in the first‐line group and 15 patients in the second‐line group died of UTUC. We reported a median OS of 18.0 months, a median PFS of 5.0 months, and an ORR of 38.6% for patients in the first‐line group; a median OS of 10.0 months, a median OS of 4.0 months, and an ORR of 27.8% for patients in the second‐line group. Complete response was observed in two patients in the first‐line group and one patient in the second‐line group with a total complete response rate of 2.8%. In the univariate and multivariate analysis, visceral metastasis with a hazard ratio of 2.4 was associate with poor OS. The most common treatment‐related adverse events included fatigue (11.3%), pruritus (10.4%), and diarrhea (6.6%). Conclusions This real‐world study suggests that ICI monotherapy is active and has acceptable toxic effects for unresectable or metastatic UTUC as first‐line therapy in cisplatin‐ineligible patients or second‐line therapy in platinum‐refractory patients.

Obejectives: To evaluate the clinical characteristics and prognostic factors of Nonseminomatous Germ Cell Tumor (NSGCT). Patients and methods: Testicular cancer (TC) survey was conducted by Department of Urology, West China Hospital from 2008 to 2018. Details such as age, tumor size, tumor markers, histopathology, clinical stage, initial treatment, follow up, and clinical outcomes were provided by the database of our center. Tumor stage was classified according to the NCCN criteria(1). Results: Orchiectomy, chemotherapy and radio-therapy were the main treatments for these patients. Clinical stage I, stage II and stage III patients accounted for 74.6% (150), 7.5% (15) and 17.9% (36), respectively. After a median follow up time of 63 months, 4 patients relapsed during observation and 3 of them died. 4 patients died because of advanced malignancies. Among CSI patients, 2 relapsed and 1 died in 3 months after orchiectomy. No recurrence was found in CSII patients. 2 out of 29 stage III cases relapsed after treatment and 3 died of advanced cancer. The 3- and 10- year OS was 95.6% and 88.7%, respectively. For all the patients, the 3- and 10-year PFS was 94.9% and 88.8%. According to our data, we found that the meatastasis and tumor size were risk factors for NSGCTs. Conclusion: The present report showed a good prognosis at non-metastatic stage(CSI). However, the prognosis of advanced disease(CSII and CSIII) is significantly worse than that of early stage. We also found that maximum tumor diameter of >5cm was a potential risk factor for NSGCT.

KEYWORDSInflammatory myofibroblastic tumors, Urogenital system, Kidney, Urinary bladder 3 Abstract Purpose: We aimed at investigate a series of inflammatory myofibroblastic tumors (IMTs) of urogenital system in multi-centers in China. Materials and methods: Within the pathologic databases at West China Hospital of Sichuan University and the Third People's Hospital of Chengdu, we identified 33 individuals with IMTs from May 2009 to January 2019 Results: A total of 33 patients with IMTs of urogenital system were identified. The median age of all the individuals was 39.5 years (range 0-74
