| Popis: | e17058 Background: Dose-dense chemotherapy is increasingly more utilized in the adjuvant treatment of patients (pts) with epithelial ovarian, fallopian tube, or primary peritoneal carcinoma (EOC), as compared to the conventional q3 week chemotherapy regimen. The safety and tolerability of the dose-dense regimen in pts ≥65 yrs old has not been well studied. We performed a retrospective analysis of pts with stage II-IV EOC treated at our institution with either regimen. Methods: We identified pts with stage II-IV EOC treated at Northwell Health from 2010-2015 who received adjuvant chemotherapy with the dose-dense (carboplatin q3 weeks/weekly paclitaxel) or the conventional (carboplatin and paclitaxel q3 weeks) regimen. Pts who received IP chemotherapy were excluded. Demographics, adverse events (AEs), dose delays/reductions and efficacy outcomes were evaluated. Results: 38 pts received conventional chemotherapy (median age 68 yrs) and 29 pts received dose-dense chemotherapy (median age 61 yrs). There were no differences in the frequency of grade ≥3 hematologic toxicities b/w the two arms. There were no differences in delayed or missed doses between the two arms but a higher proportion of dose reductions in the dose-dense arm ( P= 0.0472). Among pts treated in the dose-dense arm, 87.5% of women < 65 yrs old had at least one grade ≥3 AE when compared to 38.5% of women ≥ 65 yrs old ( P= 0.0161). There were no differences in dose delays, dose reductions, or missed doses when compared by age in the dose-dense arm. In the dose-dense arm, stage III-IV pts < 65 yrs old had a median time to progression (TTP) of 13.0 mo (95% CI, 6.7-13.8) and a median overall survival (OS) of 48.3 months (95% CI, 11.5-48.3). Pts ≥ 65 yrs old had a median TTP of 10.9 mo (95% CI, 8.7-12.7) and median OS of 35.9 mo (95% CI, 30.8-not reached). There was no difference in TTP ( P= 0.2154) or OS ( P= 0.9260) between the two cohorts. Conclusions: Our institutional experience of administering dose-dense adjuvant chemotherapy to women with EOC suggests that this regimen is likely safe in women ≥ 65 yrs old, with similar efficacy outcomes and should be considered for this population. Further study with larger sample sizes and in prospective trials is warranted. |
