Cisplatin with ionizing radiation

Investigators found that human breast cancer cell lines with BRCAl mutations showed a twofold to fourfold increase in apoptosis after treatment with ionizing radiation, cisplatin, or doxorubicin, compared with cells free of mutations. They also found that BRCAl tumor cell lines were resistant to other agents, such as paclitaxel (Taxol) and docetaxel (Taxotere), treatments used commonly in ovarian cancer and advanced-stage breast cancers. 

Finally, replication-competent viral vector systems have been combined with standard cancer therapy in animal models, resulting in synergistic effects. This has, for example, been shown for ONYX-015 plus cisplatin or ionizing radiation [108,112] and for an AdElB 55k-deleted virus expressing HSV-tk (plus ganciclovir) in combination with the topoisomerase inhibitor topotecan [114].
