POSTSURGICAL SURVEILLANCE OF PATIENTS WITH FIGO STAGE I/II ENDOMETRIAL ADENOCARCINOMA

Objective: To examine the effect of postsurgical surveillance on survival of patients with FIGO stage I/II endometrial adenocaricinoma. Methods: We examined the records of 354 patients who underwent primary surgical therapy for FIGO stage I/II endometrial adenocarcinoma. In patients who developed recurrent disease, we determined whether symptoms or signs of disease were present at recurrence and whether there was evidence of disease on Pap smear or chest radiograph. Results: Among the 354 patients in this study, 44 (12%) developed recurrent disease. Sites of recurrence included 12 (27%) isolated vaginal, 12 (27%) pelvis with vagina or abdomen, 4 (10%) isolated lung, 13 (29%) pelvic/abdominal with other distant sites, and 3 (7%) other distant sites. At diagnosis of recurrence 61% of patients had symptoms related to their cancer, 68% had physical exam findings suggestive of recurrence, and 84% had symptoms and/or signs. Findings consistent with recurrent cancer were detected by Pap smear in 25% and on chest radiograph in 20%. Among the 44 patients who developed recurrent disease, 8 (18%) remain alive without evidence of disease, including 6/12 (50%) with isolated vaginal disease and 2/34 (6%) with other patterns of recurrent disease (P = 0.01). Among the 12 patients with isolated vaginal recurrence, 1/3 (33%) in whom recurrent disease was diagnosed by Pap smear alone was salvaged compared to 5/9 (56%) who had symptoms or signs of vaginal recurrence. None of the three patients in whom an abnormal chest radiograph was the only evidence of recurrence survived. Conclusions: Because of the low recurrence rate of FIGO stage I/II endometrial cancer and the paucity of effective second-line treatment, surveillance Pap smears and chest radiographs appear to have little impact on survival. Although few asymptomatic potentially curable recurrences were detected due to surveillance examinations, the value of psychological reassurance associated with a normal examination is difficult to quantitate.
