Abstract:
AIM:To evaluate the effect of preoperative transcatheter arterial chemoembolization (TACE) on proliferation of hepatocellular carcinoma (HCC) cells. METHODS:A total of 136 patients with HCC underwent liver resection. Of 136 patients, 79 patients received 1 to 5 courses of TACE prior to liver resection (TACE group), who were further subdivided into four groups: Group A (n = 11) who received 1 to 4 courses of chemotherapy alone; Group B (n = 33) who received 1 to 5 courses of chemotherapy combined with iodized oil; Group C (n = 23) who received 1 to 3 courses of chemotherapy combined with iodized oil and gelatin sponge; and Group D (n = 12) who received 1 to 3 courses of chemotherapy combined with iodized oil, ethanol and gelatin sponge. The other 57 patients only received liver resection (non-TACE group). The expressions of Ki-67 and proliferating cell nuclear antigen (PCNA) protein were detected in the liver cancer tissues by immunohistochemical method. RESULTS:The Ki-67 protein expression was significantly lower in Groups C and D as compared with non-TACE group (31.35% +/- 10.85% vs 44.43% +/- 20.70%, 30.93% +/- 18.10% vs 44.43% +/- 20.70%, respectively, P < 0.05). The PCNA protein expression was significantly lower in Groups C and D as compared with non-TACE group (49.61% +/- 15.11% vs 62.92% +/- 17.21%, 41.16% +/- 11.83% vs 62.92% +/- 17.21%, respectively, P < 0.05). The Ki-67 protein expression was significantly higher in Group A as compared with non-TACE group (55.44% +/- 13.72% vs 44.43% +/- 20.70%, P < 0.05). The PCNA protein expression was significantly higher in Groups A and B as compared with non-TACE group (72.22% +/- 8.71% vs 62.92% +/- 17.21%, 69.91% +/- 13.38% vs 62.92% +/- 17.21%, respectively, P < 0.05). CONCLUSION:Preoperative multi-material TACE suppresses the proliferation of HCC cells, while a single material embolization and chemotherapy alone enhance the proliferation of HCC cells.
