Dose-Dense Epirubicin and Cyclophosphamide Followed by Docetaxel as Adjuvant Chemotherapy in Node-Positive Breast Cancer

الملخص EN

Background.

Adding taxanes to anthracycline-based adjuvant chemotherapy has shown significant improvement particularly in node-positive patients, but optimal dose and schedule remain undetermined.

Objectives.

This study aimed to assess the feasibility of dose-dense epirubicin and cyclophosphamide followed by docetaxel in node-positive breast cancer.

Methods.

All Patients first received 4 cycles of epirubicin (100 mg/m2) and cyclophosphamide (600 mg/m2) at 2-week interval then followed by docetaxel (100 mg/m2) at 2-week interval for 4 cycles, with daily Pegfilgrastim (G-CSF) that was administered in all patients on days 3–10 after each cycle of epirubicin and cyclophosphamide infusion.

Results.

Fifty-eight patients with axillary lymph node-positive breast cancer were enrolled in the study, of whom 42 (72.4%) completed the regimen.

There were two toxicity-related deaths, one patient due to grade 4 febrile neutropenia and the other due to congestive heart failure.

Grade 3/4 neutropenia and febrile neutropenia were 13.8% and 5.1%.

The most common grade 3/4 nonhematological complications were as follows: skin-nail disorders (48.3%), hand-foot syndrome (34.4%), paresthesia (38%), arthralgia (27.5%), and paresis (24.1%).

Conclusions.

Dose-dense epirubicin and cyclophosphamide followed by docetaxel with G-CSF support are not feasible, and it is not recommended for further investigation.
