Metastasis-directed therapy significantly improved outcomes in patients with oligometastatic prostate cancer, according to a first-of-its-kind meta-analysis evaluating the addition of metastasis-directed radiation therapy to standard-of-care treatment. According to corresponding author Chad Tang, M.D., associate professor of Genitourinary Radiation Oncology, gathering level one evidence of the benefits of MDT in this cancer type has been a challenge due to several factors. Most significant among them are that only a small number of patients have oligometastatic cancer – meaning they have multiple metastases but not enough to be considered widely metastatic – and the relative indolence of oligometastatic disease.
“If we can identify and treat this disease in the narrow window before it spreads too far, we know that patient outcomes are significantly better. But gathering this data is difficult,” Tang said. “By bringing together all available patient data from randomized clinical trials, we have provided the best evidence to date that MDT improves patient outcomes.”
