Table 2. The relationship between chemosensitivity and the RNA expression levels of IMPs and Lin28/Lin28B (n=80).

	IMP1			IMP2			IMP3			Lin28B			Lin28
	L	H		L	H		L	H		L	H		L	H
Resistant	20	20	P=0.90	19	21	P=0.50	13	27	P=0.003	15	25	P=0.04	22	17	P=0.18
Sensitive	21	19		17	23		26	14		24	16		17	24

Abbreviations: H=high expression, mRNA expression value over than median value; IMP=insulin-like growth factor 2 mRNA-binding proteins (IGF2BPs; refered to as IMPs); L=low expression, mRNA expression value less than median value.

Sensitive was defined as a recurrence after a platinum-free interval ⩾6 months. Resistant was defined as a recurrence after a platinum-free interval of <6 months.
