[Examination of the effects of age on prognostic factors of squamous cell carcinoma of the uterine cervix].

Abstract

The presence or absence of an association between age and prognostic factors of squamous cell carcinoma of the uterine cervix, including histologic cell type, depth of invasion, stromal reaction, CPL classification, and lymph node metastasis, was examined in 380 patients who had undergone radical hysterectomy. Age affected the rate of lymph node metastasis according to depth of invasion, and the metastasis rates in patients with invasion of 2/3 of the lateral side of the muscular layer (gamma type) in groups of patients in their 30s, 40s, 50s, and 60s were 40.0% (4/10), 59.3% (16/27), 36.7% (18/49), and 21.6% (8/37), respectively. Similarly, the metastasis rates in patients with invasion of the parametrium (delta type) in the above age groups were 100% (1/1), 72.7% (8/11), 46.4% (13/28), and 36.7% (11/30). Lymph node metastasis was significantly less in patients in their 60s than those in their 40s (gamma: p less than 0.01, delta: p less than 0.05). Moreover, 5-year survival rates of patients with lymph node metastasis (tested by Kaplan-Meier method) were 33.3% (N = 4), 65.0% (N = 15), 81.9% (N = 17), and 100% (N = 8) in groups of patients in their 30s, 40s, 50s, and 60s respectively, in the gamma type, and 45.0% (N = 8), 45.7% (N = 10), and 79.6% (N = 11) in groups of patients in their 40s, 50s, and 60s respectively, in the delta type. A significant difference was noted between the group of patients in their 60s and other age groups (gamma: p less than 0.01, delta: p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
