TACE followed by 3‐DCRT vs chemoembolisation

Proportion of participants without tumour response (CR+PR) · primary hepatocellular carcinoma

TACE followed by 3‐DCRT may leads to lower proportion of participants without tumour response (CR+PR) compared with TACE (low certainty).

TACE followed by 3‐DCRT vs chemoembolisation

Non‐serious adverse events: leukopenia · primary hepatocellular carcinoma

It is very uncertain whether TACE followed by 3‐DCRT changes non‐serious adverse events: leukopenia compared with TACE (very low certainty).

TACE followed by 3‐DCRT vs chemoembolisation

Proportion of participants without serum AFP normalisation · primary hepatocellular carcinoma

It is very uncertain whether TACE followed by 3‐DCRT changes proportion of participants without serum AFP normalisation compared with TACE (very low certainty).

Altered WBRT fractionation schedules vs WBRT control

Overall survival: higher‐dose WBRT vs control (3000 cGy/10 daily fractions)No. of participants: 846(4 RCTs) · patients with newly diagnosed multiple brain metastases

Altered WBRT fractionation schedules probably leads to higher overall survival: lower‐dose WBRT vs control WBRT (3000 cGy/10 daily… compared with WBRT control (moderate certainty).

WBRT with radiosensitisers (radiosen) vs WBRT

Brain tumour response rates: complete response (CR) and partial response (PR) combinedNo. of participants: 847(6 RCTs) · patients with newly diagnosed multiple brain metastases

WBRT with radiosensitisers (radiosen) showed no clear difference in brain tumour response rates: complete response (CR) and partial… compared with WBRT alone (high certainty).

Overall survivalNo. of participants: 2631(8 RCTs) · patients with newly diagnosed multiple brain metastases

WBRT and radiosurgery showed no clear difference in overall survivalNo. of participants: 358(2 RCTs) compared with WBRT (moderate certainty).

1‐Year overall brain control ratesNo. of participants: 400(3 RCTs) · patients with newly diagnosed multiple brain metastases

WBRT and radiosurgery leads to lower 1‐Year overall brain control ratesNo. of participants: 400(3 RCTs) compared with WBRT (high certainty).
