Patient characteristics are detailed in Table 1. The patients’ median age was 71 years (range: 35–100 years). Among 262 patients, 174 (66.4%) were male and 88 (33.6%) were female. Seventy six of 245 (31.0%) patients were treated with radiotherapy, of which 54 of 76 (71.1%) received preoperative therapy. Disease-free and OS data were available for 211 and 248 patients, respectively. Patients were followed for a median period of 3.2 years (range: 0−12.6 years). Local recurrence of disease occurred in 82/211 (38.9%) patients. The median time to recurrence was 2.12 years. At the time of the study, 141/248 (56.9%) patients were alive. The median time to death was 2.5 years following surgery (range: 0−11.1 years). Among patients who received preoperative radiotherapy, local recurrence occurred in 6/54 (11.1%) patients and median time to recurrence was 2.61 years (range: 0.75−4.29 years). All six patients (100%) had died by the end of this study. The median time to death following recurrence was 3.81 years (range: 0.6−10.9 years).
