of PFPE (PE400, 400 mg/kg BW).
The tumor volume was measured every 2 days and the rats
were sacrificed at the end of experiment. The tumors were isolated,
weighted, and kept at 80 °C immediately until use (Sriwiriyajan
et al., 2016). Tumor volume suppress rate was equal to
1 −( )× 100% tumor volume of treatment
tumor volume of control .
