ABSTRACT Since transitional cell carcinoma (TCC) of the upper urinary tract is a relatively uncommon malignancy, the role of adjuvant radiotherapy is unknown.
We treated 133 patients with TCC of the renal pelvis or ureter at our institution between 1998 and 2008. The 67 patients who received external beam radiotherapy (EBRT) following surgery were assigned to the radiation group (RT). The clinical target volume included the renal fossa, the course of the ureter to the entire bladder, and the paracaval and para-aortic lymph nodes, which were at risk of harbouring metastatic disease in 53 patients. The tumour bed or residual tumour was targeted in 14 patients. The median radiation dose administered was 50 Gy. The 66 patients who received intravesical chemotherapy were assigned to the non-radiation group (non-RT).
The overall survival rates for the RT and non-RT groups were not significantly different (p = 0.198). However, there was a significant difference between the survival rates for these groups based on patients with T3/T4 stage cancer. A significant difference was observed in the bladder tumour relapse rate between the irradiated and non-irradiated bladder groups (p = 0.004). Multivariate analysis indicated that improved overall survival was associated with age < 60 years, T1 or T2 stage, absence of synchronous LN metastases, and EBRT. Acute gastrointestinal and bladder reactions were the most common symptoms, but mild non-severe (> grade 3) hematologic symptoms also occurred.
EBRT may improve overall survival for patients with T3/T4 cancer of the renal pelvis or ureter and delay bladder tumour recurrence in all patients.

    ABSTRACT: The aim of this study was to evaluate the prognostic significance of the ureteral location of the upper tract urinary carcinoma (UTUC). Between January 1998 and December 2007, 161 patients with UTUC were operated in our center. Tumors were located on renal pelvis in 51% of cases, on the ureter in 34% of cases and in both locations in 15% of cases. Nephroureterectomy was performed in 79.5% of cases (128/161) whereas a conservative treatment was performed in 20.5% of cases (33/161). In our series, 29.8% of patients had primary bladder cancer and 14.3% had synchronous bladder tumor. At a median follow-up of 42.5 months, 38.6% of patients developed bladder recurrence and 4.8% developed controlateral upper tract tumor. In multivariate analysis, ureteral location and existence of synchronous bladder tumor were independent prognostic factors of bladder recurrence (P=0.009 and P=0.025, respectively). Multivariate analysis retained T-stage and ureteral location as independent prognostic factors in both overall and disease-free survival (P=0.002 and P=0.0008 respectively for ureteral location). Ureteral location was an independent prognostic factor of bladder recurrence and was associated with a poorer prognosis.
