Our study demonstrated tumor grade and surgical margins had significant prognostic influence and the Gronchi's nomogram has an excellent applicability in predicting survival of STS patients. J. Surg. Oncol. 2016;113:355-360. © 2016 Wiley Periodicals, Inc.

Urothelial carcinoma of the urinary bladder in young adults is usually associated with low grade and low stage. Invasive bladder cancer had no worse a survival rate than superficial bladder cancer.

A total of 62 patients with retroperitoneal or genitourinary sarcoma was treated at our institutions during the last 46 years. Of the patients 51 were followed for at least 5 years or until they died (median followup 11 years); 5 patients were lost to followup. The most common site was the retroperitoneum. Liposarcoma, leiomyosarcoma and malignant fibrous histiocytoma were the most common tumors (74 per cent). Tumors were completely resected in 42 patients (68 per cent) and incompletely resected in 11, while a biopsy only was performed in 9. Some patients also received adjuvant radiation therapy and/or chemotherapy. There were no long-term survivors among patients with unresectable tumors. Over-all 3 and 5-year survival rates were 68 and 39 per cent, respectively. The histological type of the tumor appeared to have prognostic significance. The highest 5-year survivals were for liposarcoma (70 per cent), malignant fibrous histiocytoma (33 per cent) and leiomyosarcoma (13 per cent). The mean survival for patients after adjuvant radiation therapy or chemotherapy was similar to that after a radical operation alone. The primary cause of treatment failure was local recurrence (45 per cent of the patients), which was detected within 3 years of complete resection in most cases (82 per cent). Complete extirpation that provided adequate margins free of tumor was the most effective initial treatment and provided the best chance for cure.

The early complication rates of RP in our patients were slightly high compared to the Western series. By standardized report, being overweight, diabetes mellitus, and use of neoadjuvant hormone therapy were identified as predictors of early complications in our series.

BackgroundProstate vaporization and enucleation is a novel treatment option for bladder outlet obstruction caused by benign prostate enlargement. This surgical technique, however, has not yet been standardized. We present our findings of using a high-power thulium laser to accomplish vapoenucleation of the prostate (ThuVEP).MethodsWe prospectively collected and analyzed data from 29 patients who underwent ThuVEP between August 2010 and May 2012. The control group included 30 patients who underwent traditional transurethral resection of the prostate (TURP). Operative variables, patient profiles, preoperative and postoperative urine flow rates, prostate volume (measured using transrectal ultrasonography), and the international prostate symptom score (IPSS) were recorded and analyzed using a two-tailed Student’s t-test and analysis of variance.ResultsThe ages (mean ± SD) of the patients were 76.1 ± 9.4 and 72.6 ± 7.4 years (p = 0.28) in the ThuVEP and TURP groups, respectively. The average urinary flow rates before and 12 months after the operation (volume/maximum flow/average flow) were 243.3/10.5/5.0 and 302.8/17.6/9.4 (in mL, mL/s, mL/s, respectively) in the ThuVEP group and 247.2/10.8/4.6 and 369.9/20.8/12.0, respectively, in the TURP group. Preoperative and postoperative IPSSs were 17.1 ± 5.0 and 6.5 ± 3.8, respectively, in the ThuVEP group and 18.2 ± 4.5 and 6.2 ± 3.3, respectively, in the TURP group. The mean ratio of the estimated postoperative residual prostate volume to the preoperative total volume was 0.47 (p = 0.449) in both groups. The overall complication rate was 20.7% in the ThuVEP group and 30.0% in the TURP group.ConclusionsOne year of follow-up showed that ThuVEP and TURP effectively alleviated subjective and objective voiding symptoms with a low rate of complications. Thus, vapoenucleation using a high-power laser is feasible in elderly patients.Trial registrationISRCTN registry with study ID ISRCTN52339705. Date assigned: 06/03/2015.
