We consider asymptomatic when there are no symptoms and recurrence is diagnosed by complementary tests requested during follow-up.Results There were 71 recurrences (16.4%) with a mean follow-up estimated by Kaplan Meier of 220.1 months (95% confidence interval (CI) 208.0–232.3). In 47 patients was symptomatic (66.2%) and in 24 patients asymptomatic (33.8%). We have not found statistically significant differences in both groups, except in the percentage of positive pelvic nodes, which was higher in the asymptomatic group (5 cases (20.8%) versus 2 cases (4.3%) p=0.04). There were no statistically significant differences in the number of local and distant recurrences (p=0.272). Asymptomatic recurrences in 5 cases (20.83%) were suspected by finding in the physical examination. Therefore, in 52 cases recurrence was suspected due to symptoms or a finding on physical examination (73.2%) and only in 19 cases due to complementary tests requested during follow-up (26.8%). Regarding the time of recurrence, we compared symptomatic and asymptomatic recurrences that occurred in the first 2 years (Hazard ratio (HR) 0.840 (Confidence interval (CI) 95% 0.470–1.502) p=0.557), from 3 to 5 years (HR 0.637 (CI 95% 1.86–2.181) p=0.473) and from 6 to 10 years (HR 0.966(95% CI 0.198–4.711) p=0.966), without finding statistically significant differences. We have compared the overall survival according to the recurrence clinic using Cox regression we have not found differences with an HR 0.964 (95% CI: 0.541–1.717) (p=0.901).Conclusion Most of the recurrences were diagnosed through a correct clinical history and physical examination. Patients with asymptomatic recurrence did not have a better prognosis than patients with symptomatic recurrence.
