VAS 0 is for before treatment; VAS 1, 2 and 3 are for treatment after 1, 2 and 3 cycles respectively; VAS 4 and 5 are for 1 and 2 cycles respectively after treatment stops. For treatment after 1, 2, 3 cycles respectively, and for 1 and 2 cycles respectively after treatment stops. ^aMesas p<0.01; For treatment after 2 and 3 cycles respectively with for treatment 1 cycles, ^bMesas p<0.01.
