Abstract

Background: Cytotoxic drugs play an important role in the management of breast cancer particularly in pre-menopausal patients and patients with triple negative breast cancer (TNBC).The adverse reactions to chemotherapeutic drugs are wide and varied. These adverse reactions to chemotherapy drugs could be haematologic and non-haematologic.


Objectives: The study aims to evaluate the toxicity and tolerance of cyclophosphamide, doxorubicin and 5-fluorouracil (CAF) combination on pre-menopausal women with breast cancer.


Materials and methods: A Doxorubicin containing regimen (CAF) consisting of cyclophosphamide 500 mg/m2, Doxorubicin 50 mg/m2, and 5-Fluorouracil 500 mg/m2 all were given on day one. During the course of the cytotoxic drugs, all the side effects both haematological and non-haematological were recorded. The data collected were analyzed using the SPSS statistical software version 23.0. (Statistical Package for Social Sciences SPSS Inc.).


Results: Forty-nine patients were recruited with age range 24 to 54 (40.92±7.98) years. Out of 49 patients, 8(16.3%) developed anaemia, 2(4.1%) leucopenia and 3(6.1%) mild thrombocytopenia during neoadjuvant chemotherapy. The majority of the patients, 41 (83.7%), did not produce significant haematologic side effects. Out of a total of 49 patients, 47 (95.9%) developed atleast one non-haematologic side effect during neoadjuvant chemotherapy. The most common side effects were: vomiting, nausea and body weakness at the frequencies of 29 (59.2%), 28 (57.1%) and 24 (50.0%), respectively.


Conclusion: The study demonstrated that neoadjuvant CAF chemotherapy was very tolerable by our patients with only minimal haematological and non-haematological toxicities. The recorded toxicities were readily managed by simple measures without need for admission.
