Purpose
Estimation of cytostatics influence used in breast cancer treatment on lysozyme activity in human tears depend on time of treatment. Material and methods 8 women were treated at the base of chemotherapy schema: docetaxel with doxorubicin and 4 women treated with schema CMF: cyclophosphamide, methotrexate, 5-fluorouracil. Lysozyme activity in tears was assessed by measurement of diameter zone of Micrococcus lysodeicticus growth inhibition. Results It was revealed that both chemotherapy schema caused statistically significant reduction of diameter zone of M. lysodeicticus growth inhibition, after first and second course of chemotherapy treatment. After second chemotherapy course CMF schema induced loss of lysozyme activity in patient‘s tears (zero mm of M. lysodeicticus diameter zone growth inhibition). Conclusions Systemic chemotherapy administered in breast cancer induce reduction of lysozyme activity in tears, that may cause higher morbidity of ocular surface infections caused by Gram-positive bacteria. keywords:
