Immunohistochemical study of insulin-like growth factor II mRNA-binding protein 3 (IMP3) protein expression in intrahepatic cholangiocarcinoma. IMP3 protein was not expressed in adjacent nontumorous tissue (A). The proportion of tumor cells positive for IMP3 immunostain varied considerably, ranging from ≤10% (B), 11–50% (C), to >50% (D). (A–D) × 400 (original magnification).

3. Fig. 2
Kaplan–Meier survival curves for 61 patients with resected, unifocal, primary intrahepatic cholangiocarcinoma (ICC) in relation to the status of insulin-like growth factor II mRNA-binding protein 3 (IMP3) expression. Patients with IMP3-positive ICCs had significantly lower disease-free survival rate (p = 0.0001) (A) And overall survival rate (p = 0.0007) (B) Than those with IMP3-negative ICCs. (+), designated presence; (−), designated absence.

Kaplan–Meier survival curves for 61 patients with resected, unifocal, intrahepatic cholangiocarcinoma (ICC) in relation to presence or absence of early tumor recurrence (ETR). Patients with ETR had significantly lower disease-free survival rate (A) and overall survival rate (B) than those without ETR (p <  and p = 0.0001, respectively). (+), designated presence; (−), designated absence.

5. Fig. 4
Kaplan–Meier analysis of survival curves in 61 patients with or without insulin-like growth factor II mRNA-binding protein 3 (IMP3) expressed intrahepatic cholangiocarcinoma (ICC) in relation to tumor stage. The p value was from comparison of all four groups (log rank test). (A) High-stage ICC with concomitant IMP3 expression was associated with the worst disease-free survival (p < 0.0001). Interestingly, low-stage ICC with concomitant IMP3 expression also had significant worse disease-free survival than low-stage ICC without IMP3 expression (p = 0.0286). (B) High-stage ICC with concomitant IMP3 expression was associated with worst overall survival (p < 0.0001), significantly worse than ICC with high-stage tumor without IMP3 expression (p = 0.0245). (+), designated presence; (−), designated absence; L-stage, designated low-stage tumor; H-stage, designated high-stage tumor.
