Expression of p53 Protein of Hepatocellular Carcinoma Cells after Transcatheter Arterial Chemoembolization / 中国医师杂志

ABSTRACT

Objective To evaluate the significance of p53 protein expression of hepatocellular carcinoma (HCCs) cells after transcatheter arterial chemoembolization(TACE). Methods A total of 136 patients with HCC underwent liver resection. One to five courses of TACE prior to liver resection were performed in 79 patients (TACE group), in which one to four courses of chemotherapy alone were performed in 11 patients (Group A), one to five courses of chemotherapy combined with iodized oil were performed in 33 patients (Group B), one to three courses of chemotherapy combined with iodized oil and gelatin sponge were performed in 23 patients (Group C), and one to three courses of chemotherapy combined with iodized oil, ethanol and gelatin sponge were performed in 12 patients (Group D). The other 57 patients only received liver resection (non-TACE group). The extent of apoptosis was analyzed by transferase-mediated dUTP nick end labeling (TUNEL) staining. The expressions of Bcl-2, Bax, Ki-67 and PCNA proteins were detected by immunohistochemical method. Results p53 protein expressions of trabecular and clear cell HCCs were significantly lower than those of pseudoglandular, solid, poorly differentiated or undifferentiated and sclerosis HCCs (P
