Abstract


OBJECTIVE    To investigate the short-term and long-term therapeutic e ffi  cacy of preoperative intra-arterial infusion chemo-embolization on stage IB2-IIB uterine cervix cancer (UCC).
METHODS     A total of 143 patients with Stage IB2-IIB UCC were divided into a clinical trial group and a control group. The patients in the clinical trial group (n  = 86) were treated with a combined therapy, i.e., preoperative intra-arterial infusion chemo-embolization, surgical therapy and postoperative radiotherapy, and those in the control group ( n = 57) were given surgical therapy and post-operative radiotherapy. The adverse effects, changes in local lesion and pathological examinations of the cancer, and the state during the surgery were observed after the intra-arterial infusion chemo-embolization. The survival rate and recurrence rate between the two groups were compared.
RESULTS     The total effective rate of the intra-arterial infusion chemo-embolization on Stage IB2-IIB UCC was 93.02%. The treatment could reduce tumor size, bring about retro-conversions of the clinical stage of the tumors and pathological grade of the cancer cells, and decrease the quantity of intra-operative blood loss as well as the operating time. It could signi fi cantly improve the 5-year survival rate ( P < 0.05), and reduce the 2 and 5-year tumor recurrence rates (P  < 0.05). Moreover, its side effects were little.
CONCLUSION     Preoperative intra-arterial infusion chemo-embolization can create conditions for radical operation, lower the postoperative recurrence rate, and improve the prognosis in the patients with UCC. It is an eff ective therapy in treating UCC .
