Popis: | Objectives Considering that adjuvant radiation therapy is one of the most common treatment methods and the influence of the clinical target volume to treatment-related toxicity, this study aimed to observe the differences in treatment failures about involved-field irradiation (IFI) without lymph node areas versus elective nodal irradiation (ENI) with lymph node areas in elderly patients with bladder cancer. Material and Methods Ninety-two elderly bladder cancer patients were analyzed from January 2010 to December 2014 in one institution. The primary inclusion criteria were previous after transurethral resection of bladder tumor or partial cystectomy with adjuvant radiotherapy, and the radiation techniques included IFI or ENI. The study required that elderly patients did not received radiotherapy before treatment. We observed treatment-related toxicity and tumor failures, evaluated local progression-free survival, estimated the 3-year overall survival, and analyzed prognostic factors, after IFI and ENI in elderly bladder cancer patients. The outcomes were determined by chi square tests, Kaplan-Meier method and Cox multiple factors analysis. Results In the experimental group, 42 patients (45.65%) received IFI, and a matched group of 50 patients (54.35%) received ENI. With a median follow-up of 31.47 months (range 4.00-86.00 months), the Kaplan-Meier analysis with a log-rank test demonstrated a statistical difference between the IFI group and the ENI group in acute toxicity (45.23% vs 72.00%, P = 0.008). However, there were no statistical differences in the 3-year overall survival rate (45.20% vs 48.00%, P = 0.860) or the duration of local progression-free survival (24.98 vs 34.30, P =0.729). Conclusions IFI is feasible in elderly bladder cancer patients, as shown by a decrease in acute toxicity and no increase in local failure. We need a large number of clinical trials and data to further confirm these results. |
