Chemoradiotherapy showed no clear difference in overall survival compared with chemoradiotherapy plus surgery (high certainty).
Extended‐field radiotherapy probably leads to lower overall survival compared with pelvic radiotherapy (moderate certainty).
Extended‐field radiotherapy probably leads to lower overall survival compared with pelvic chemoradiotherapy (moderate certainty).
Hypofractionated radiotherapy showed no clear difference in overall survival compared with conventional radiotherapy (moderate certainty).
The review found no eligible studies for this question.

Hysterectomy (simple or radical) with radiotherapy showed no clear difference in overall survival Median compared with radiotherapy alone (low certainty).
It is very uncertain whether hysterectomy (simple or radical) with chemoradiotherapy changes overall survival Median compared with chemoradiotherapy alone (very low certainty).
Hysterectomy (simple or radical) with chemoradiotherapy showed no clear difference in overall survival Median compared with internal radiotherapy (brachytherapy) with chemoradiotherapy (low certainty).
Daily conventionally fractionated radiotherapy probably leads to higher overall survival compared with no radiotherapy (supportive care alone) (moderate certainty).
It is very uncertain whether surgery plus whole brain radiotherapy (WBRT) changes overall survival compared with stereotactic radiosurgery (very low certainty).
Surgery plus whole brain radiotherapy (WBRT) showed no clear difference in overall survival compared with stereotactic radiosurgery plus WBRT (low certainty).
