Ovarian epithelial carcinoma is the most common form of ovarian cancer, causing more deaths than any other cancer in women with gynecologic malignancies in the United States. The poor outcome for women with late-stage ovarian cancer underscores the need for early detection strategies and for new treatment options to be developed. High-intensity focused ultrasound (HIFU) is a therapeutic modality that is safe and effective against various types of solid tumors, and has the potential to serve as a treatment for ovarian cancer. Use of an appropriate animal model is important in obtaining relevant data for translational research. The purpose of the study reported here was to modify and create an immunocompetent orthotopic tumor isograft model for evaluation of intra-operative HIFU application. This model would resemble the clinical presentation of human patients with late-stage ovarian cancer. We were able to consistently produce a surgical model that presented with a single large, intra-abdominal tumor nodule within the left ovarian bursa, as well as multiple small nodules on the surface of other organs and tissues. This technique may also be used to refine other tumor models, using the ovarian bursa as an implant site for heterotopic tumor isografts.
