PURPOSE: A simple measure to predict chemotherapy tolerance in elderly patients would be useful. We prospectively tested the association of baseline Instrumental Activities of Daily Living (IADL) score with ability to complete 4 cycles of first line chemotherapy without dose reductions or >7days delay in elderly ovarian cancer patients.

PATIENTS AND METHODS: Patients' age ≥70 along with their physicians chose between two regimens: CP (Carboplatin AUC 5, Paclitaxel 135mg/m

RESULTS: Two-hundred-twelve women were enrolled, 152 selecting CP and 60 selecting C. Those who selected CP had higher baseline IADL scores (p<0.001). After adjusting for age and PS, baseline IADL was independently associated with the choice of regimen (p=0.035). The baseline IADL score was not found to be associated with completion of 4 cycles of chemotherapy without dose reduction or delays (p=0.21), but was associated with completion of 4 cycles of chemotherapy regardless of dose reduction and delay (p=0.008) and toxicity, with the odds ratio (OR) of grade 3+ toxicity decreasing 17% (OR: 0.83; 95%CI: 0.72-0.96; p=0.013) for each additional activity in which the patient was independent. After adjustment for chemotherapy regimen, IADL was also associated with overall survival (p=0.019) for patients receiving CP.

CONCLUSION: Patients with a higher baseline IADL score (more independent) were more likely to complete 4 cycles of chemotherapy and less likely to experience grade 3 or higher toxicity.
