The Use of Lattice Radiation Therapy (LRT) in the Treatment of Bulky Tumors: A Case Report of a Large Metastatic Mixed Mullerian Ovarian Tumor

摘要

The objective of this teaching case is to report the excellent results of using lattice radiation therapy (LTR) for the treatment of a large metastasis from ovarian carcinosarcoma. This new technical concept extrapolates the traditional spatially fractionated radiation therapy (GRID) technique to advanced three-dimensional (3D) high-dose radiation therapy using modern instrumentation in radiation oncology. We report a case of a 61-year-old female with a large metastatic mass from ovarian carcinosarcoma treated by this procedure with excellent clinical and image-based follow-up results for more than four years.
