Cancer medicine, 5(1), 61-73. https://doi.org/10.1002/cam4.553

In comparison to more differentiated cells, prostate cancer stem-like cells are radioresistant, which could explain radio-recurrent prostate cancer. Improvement of radiotherapeutic efficacy may therefore require combination therapy. We have investiga...
