Effects of preoperative radiotherapy or chemoradiotherapy on postoperative pathological outcome of cervical cancer——from the large database of 46,313 cases of cervical cancer in China

To investigate the effect of preoperative radiotherapy or chemoradiotherapy combined with radical surgery on pathological outcomes in cervical cancer patients.
