Objective: To estimate the probability of and risk factors for the recurrence of invasive cervical carcinoma over 5 years after initial therapy.
Methods: Patients (n = 827) with invasive cervical carcinoma were treated and received follow-up care for up to 29 years. Late recurrence was defined as recurrence more than 5 years after initial therapy. The probability of late recurrence was evaluated in terms of clinical stage, histologic type, and type of initial therapy.
Results: Late recurrence was seen in 21 of 569 patients who had survived 5 years (3.7%). Recurrence rates were 1.8% (six of 331) in stage I, 5.2% (eight of 154) in stage II, 8.6% (seven of 81) in stage III, and 0% (none of three) in stage IV. The probability of late recurrence in patients with stage I disease was significantly lower than that in stage II and stage III diseases (stage I compared with stage II, P = .038, stage I compared with stage III, P = .002). Late recurrence occurred in 21 (3.8%) of 547 cases of squamous cell carcinoma, whereas no late recurrences were found in 22 cases of adenocarcinoma. The late recurrence rate in patients who received radiation (7.1%, 17 of 241) was significantly higher than that in patients who received surgery (1.2%, four of 328; P = .001).
Conclusion: Patients with uterine cervical squamous cell carcinoma, especially those with stage II or stage III diseases who received radiation therapy as initial treatment, warrant annual follow-up care beyond the standard 5 years after initial therapy.
