Abstract
Aims:Docetaxel, Doxorubicin, Cyclophosphamide (TAC) is an intensive chemotherapy regimen; however, being highly myelosuppressive, its usage is limited in developing countries and hence merits exploration for feasibility and efficacy. Materials and Methods: This was a retrospective audit of medical records of breast cancer patients receiving TAC chemotherapy) from 2004 to 2008. Demographic details, toxicity, and outcome analysis were carried out. Results: A total of 133 patients (126 in [neo] adjuvant and 7 in metastatic setting) received TAC chemotherapy. The median age was 45 (21–67) years; 31% had coexisting diabetes and 12% hypertension. The delivered dose intensity was 94%. Discontinuation rate was 21/133 (15.8%) and the most common reason was hematological toxicity. There were 43 (32%) cases of febrile neutropenia and 2 (1.5%) Grade III thrombocytopenia with 3 (2%) toxic deaths. Grade III gastrointestinal toxicity (diarrhea) occurred in 35 (26%) and cardiac toxicity (congestive cardiac failure) in 2 (1.5%) patients. On univariate analysis, none of the variables (baseline serum albumin, hemoglobin, disease stage, or age) was found significant for chemotoxicity. At a median follow-up of 27 months (0.13–71.30 months), the estimated median disease-free survival (DFS) was 52 months in locally advanced group; however, the early breast cancer cohort has not reached to median DFS. Conclusions: TAC is an effective regimen but has significant toxicity despite the use of primary prophylactic Granulocyte Colony-Stimulating-Factor (G-GSF), including a small possibility of death. It can be considered “practically feasible” regimen in the adjuvant setting in carefully selected, fit patients.
