Epithelial ovarian cancer in the elderly. The Memorial Sloan-Kettering Cancer Center experience.

Overview

abstract

BACKGROUND: There is evidence of differences between older (> or = 65 years of age) and younger (< 65 years of age) women with ovarian cancer. METHODS: To evaluate differences in the care of older versus younger patients with ovarian cancer, a retrospective review was conducted of the records of 146 patients who had their initial surgery for ovarian cancer at the Memorial Sloan-Kettering Cancer Center from January 1987-January 1991. RESULTS: There was a significant difference in stage at presentation between the older (48 patients) and younger (98 patients) populations (Stage I/II: older 10%; younger 25%; P < 0.05). Although there was no statistically significant difference in the distributions of patients according to tumor grade between the two groups, 10% of the younger patients had ovarian cancer of low malignant potential, compared to only 2% of older patients (P < 0.1). Forty-six percent of the younger patients entered an intensive initial chemotherapy trial compared to only 17% of the older patients (P < 0.001), principally due to comorbid medical conditions (e.g., heart disease). Finally, whereas the relative number of younger to older patients with ovarian cancer undergoing initial surgery at this institution was 2:1, the relative number of totally new patients to the service (including referral for initial treatment or salvage programs) was 4:1 (P < 0.001), suggesting that older patients with ovarian cancer are less likely to be referred for secondary experimental programs than for initial treatment. CONCLUSIONS: These data suggest that there are major differences between the presentation and treatment strategies of older compared to younger patients with ovarian cancer.
