Researchers destroy cancer with cryoablation & nanoparticle-encapsulated anticancer drug
Date:3/13/2014

Combining nanodrug-based chemotherapy and cryoablation provides an effective strategy to eliminate cancer stem-like cells (CSCs) the root of cancer resistance and metastasis, which will help to improve the safety and efficacy of treating malignancies that are refractory to conventional therapies.

Cryoablation (also called cryosurgery or cryotherapy) is an energy-based, minimally invasive surgical technique that has been investigated to treat a variety of diseases including cancer, which is done by freezing the diseased tissue to subzero temperature to induce irreversible damage. It is particularly attractive for fighting against breast cancer due to its excellent cosmetic outcome to preserve the organ with unnoticeable scar formation on skin. However, cryoablation alone has limited effectiveness on eradicating cancer stem-like cells (CSCs), which may lead to cancer recurrence and/or metastasis post operation. A team of researchers from the Department of Biomedical Engineering and Comprehensive Cancer Center at The Ohio State University introduced an innovative strategy by combining cryoablation with nanoparticle-medicated chemotherapy and demonstrated that the combined therapy can significantly augment the destruction of CSCs, resulting in eliminating nearly all CSCs. This technology provides a new approach to overcome drug resistance of CSCs and improve the safety and efficacy of cancer cryoablation. The report appears in the latest issue of the journal TECHNOLOGY.

"This novel combined therapy of cryoablation and nanodrug is a significant step forward in improving the safety and efficacy of fighting against cancer. Our study provides the first account of minimizing cancer recurrence by destroying the cancer stem-like cells in the field of cryoablation for cancer treatment." said Xiaoming He, Ph.D., of The Ohio State University and senior author of this paper. "It is valuable to facilitate the clinical applications of cryoablation by
