document: Noteworthy, the combination of TrQβ@b-3WJsiEGFR Let-7g pre-treatment with 2Gy X-ray irradiation provided nearly complete suppression of tumour progression (8.9 ± 12.5 mm3 on Day 41, and no significant tumour recurrence was observed until Day 50 using this gene-silencing-enhanced radiotherapy), which resulted in approximately 50% treated mice surviving over 60 days (median survival = 60 days). Comparing TrQβ@b-3WJsiEGFR Let-7g + 2Gy X-ray irradiation treatment group with other treatment groups,
