OBJECTIVES: To determine whether the Memorial Sloan Kettering Frailty Index (MSK-FI) is associated with decision-making in older women surgically treated for advanced-stage ovarian cancer.
METHODS: We retrospectively applied the MSK-FI to women ≥70 years with newly diagnosed advanced-stage ovarian cancer surgically treated at our institution from 01/2001-05/2017. MSK-FI components, including 10 comorbidities and functional assessment, were extracted from medical records. The MSK-FI ranges from 0 to 11, with higher scores indicating greater frailty. The primary outcome was the association between frailty and rate of primary debulking surgery (PDS), for which a multivariable logistic regression was used, adjusted for stage and histology.
RESULTS: We identified 430 women treated with PDS (n = 231, 54%) or neoadjuvant chemotherapy/interval debulking (n = 199, 46%) with complete data. MSK-FI score distribution was: "0", 95 patients (22%); "1", 172 (40%); "2", 89 (21%); and "3+", 74 (17%). More-frail patients were less likely to have undergone PDS (OR for a unit increase of MSK-FI: 0.64; 95%CI, 0.53-0.77; p < 0.0001). Grade 3+ complications and unintended intensive care admission occurred in 40 (9%) and 38 (9%) women, respectively, but were not associated with frailty (OR 1.21; 95%CI, 0.96-1.52; p = 0.11). More-frail patients were more likely to delay postoperative chemotherapy (non-linear association p = 0.009) and less likely to enroll in research (OR 0.84; 95%CI, 0.70-1.00; p = 0.049). Greater frailty was associated with poorer overall survival (HR 1.16; 95%CI, 1.05-1.30; p = 0.005).
CONCLUSIONS: Frailty, as calculated by the MSK-FI, is strongly associated with treatment approach in older women with advanced ovarian cancer, suggesting objective or subjective correlates of the MSK-FI influence decision-making.
