Cisplatin is the generic name for Platinol-AQ, a type of chemotherapeutic drug known as a platinum drug. Once inside cancer cells, cisplatin binds to DNA, cross-links the strands of the DNA, and cross-links the DNA to proteins. Due to the cross-linking in DNA and protein, multiplication of the cancer cell is inhibited. Furthermore, the treated cancer cell experiences apoptosis, a programmed process in which the cancer cell undergoes destruction of itself.
Some women with breast cancer of Stage IIIB and higher or recurrent breast cancer receive adjuvant (i.e., post-surgical) treatment with cisplatin alone or in combination with other types of chemotherapeutic drugs.
