Dose dense carboplatin paclitaxel improves progression free survival in patients with endometrial cancer Academic Article uri icon

abstract

  • Objective Pilot study to assess the value of weekly paclitaxel plus carboplatin every 3weeks (dose dense regimen, DD) compared to the standard 3-weekly protocol in the adjuvant setting for endometrial cancer. Methods Retrospective cohort study comparing consecutive patients with high and intermediate-high risk endometrial cancer, undergoing DD protocol (from 2011 to 2015) to a non-overlapping historical cohort with similar characteristics who received treatment every three weeks (2008–2011). Results 122 patients with endometrial cancer were included in the study, of these, 61 patients received the dose dense protocol and 61 were treated with the standard 3-weekly protocol. After a median follow-up of 61.6months in the 3-weekly cohort, compared with 41.6months in the DD cohort, 40 progressions were recorded. 29 progressions were observed in women treated in the standard protocol, with a three years progression free survival (PFS) of 57.4%, compared to 11 progressions observed in patients in the DD schedule, with a three years PFS of 79.5% ( P =0.03). Patients who were treated with the DD protocol were less likely to have progression events compared to the standard cohort with a hazard ratio of 0.4 on multivariate analysis (CI 95%, 0.2–0.8, P =0.01), had significantly less distant metastases ( P =0.01), and had improved overall survival when diagnosed with advanced stage disease ( P =0.02). Complaints of musculoskeletal pain were more frequent in the standard cohort ( n =17, 27.9%) compared to the dose dense cohort ( n =4, 6.6%), P =0.005. Conclusion Preliminary data suggests that dose dense chemotherapy might be a reasonable and superior option for adjuvant treatment of endometrial cancer, compared to standard chemotherapy.
