Abstract Objective: To explore the clinical effect of paclitaxel combined with platinum neoadjuvant chemotherapy (NACT) in the treatment of locally advanced cervical cancer (LACC) and the influence on the expression of second mitochondria-derived activator of caspase (Smac), apoptosis inhibiting gene (Survivin) and matrix metalloproteinase -2 (MMP-2). Methods: 76 patients with LACC were divided into the study group and the control group by random number table method, 38 cases in each group. Patients in the study group were treated with paclitaxel + cisplatin chemotherapy, while patients in the control group were treated with cisplatin +5- fluorouracil (5-FU) chemotherapy. The short-term curative effect, operation indexes, postoperative lymph node metastasis and the expression of Smac in cervical cancer tissues were compared between the two groups. Changes of serum levels of Survivin and MMP-2 levels before and after treatment were observed, and the incidence of toxic and side reactions was recorded. Results: The response rate of the study group was higher than that of the control group. The operation time, intraoperative blood loss, postoperative lymph node metastasis rate and the positive rate of Smac in the cervical cancer tissues in the study group were shorter / less / lower than those in the control group (P < 0.05). After 2 courses of chemotherapy, serum levels of Survivin and MMP-2 in the two groups were decreased, and the levels in study group were lower than those in the control group (P < 0.05). There was no significant difference in the incidence of toxic and side effects between the two groups (P > 0.05). Conclusion: Paclitaxel combined with platinum NACT is markedly effective in the treatment of LACC. The regimen can reduce the blood loss, shorten the operation time, reduce the expression of Smac, Survivin and MMP-2 and inhibit tumor metastasis. It is conducive to the prognosis of the disease but attention should be paid to toxic and side effects.
