title: Age as a prognostic factor for recurrence in patients with endometrial carcinoma.
abstract: OBJECTIVE
  The aim of this study was to evaluate age as a prognostic factor for recurrence in endometrial cancer patients treated with primary surgery.
  
  
  METHODS
  Between 1983 and 1998, 455 endometrial cancer patients underwent primary surgery at our institution. Patients were divided into three age groups based on age at diagnosis: Group A (age <60, n = 156), B (age 60-69, n = 147), and C (age >/=70, n = 152). Clinicopathologic, treatment factors, and outcome were compared among the three groups. Prognostic factors were evaluated by univariate and multivariate analysis.
  
  
  RESULTS
  The three age groups had a similar distribution of most pathologic features including stage, histology, cervical involvement, positive cytology, adnexal involvement, nodal metastases, serosal involvement, and lymphovascular invasion (LVI). Older women had a higher rate, however, of deep (>1/2) myometrial invasion (P < 0.0001) and grade 3 tumors (P < 0.0001). The extent of surgical staging and use of adjuvant radiation therapy were similar. Five-year disease-free survivals (DFS) of Groups A, B, and C were 74.3, 70.2, and 60.3%, respectively (P = 0.08). A significant difference in DFS was seen when Groups A and B were combined and compared with Group C (72.0 vs 60.3%, P = 0.03). Multivariate analysis confirmed the significance of race, stage, grade, and LVI. Age was not found to be associated with recurrence (HR 1.1, 95% C.I. 0.91-1.5, P = 0.21).
  
  
  CONCLUSIONS
  Our results reveal that, in a large cohort of comparably staged and treated endometrial carcinoma patients, age is not a prognostic factor for recurrence.
