Methods: 20women with locally advanced squamous cervical cancerreceived consecutive infusion chemotherapy of five days ofcisplatin and adriamycin via the superselective uterineartery. The response to chemotherapy was evaluated bygynecologic examination and ultrasonography 3 weeks after chemotherapy. The changes of apoptotic index (AI), proliferation index (PI) and p53 expression of tumor cellswere detected by immunohistochemical technique.Results: The clinical response rate of locally advancedsquamous cervical cancer to uterine artery infusionchemotherapy was 70%. No change of PI was found 3 weeks after treatment, but AI significantly increased from2.79?.76 to 4.29?.13 (P<0.01), and AI/PI from 5.68?.21 to 9.00?.95 (P<0.05). On the contrary, the expression of p53was significantly decreased (P<0.05). Patients whoresponded to chemotherapy showed higher PI before chemotherapy and significantly increased AI and AI/PIafter chemotherapy than non-responders (P<0.05).Conclusion: Higher PI was an indication for neoadjuvantintraarterial chemotherapy. One more cycle ofchemotherapy should be given to those who have significantly increased AI or AI/PI after chemotherapy, while definite treatment such as surgery or/and radiotherapy should be immediately given to those patients without increased AI or AI/PI.展开更多

Results:The local tumor regression rate was 93.55%.Postoperative pathologic examination showed that no cervical tumor residue in stumps were found in 61 of 62 patients who underwent radical hysterectomy.Large quantity of necrotic tissue appeared on primary tumor.In 16 patients with positive lymph nodes,15 demonstrated necrotic lymph nodes.Conclusion:Internal iliac ar- terial infusion chemotherapy could effectively reduce tumor volume,increase surgical success rate and decrease lymph nodes and subclinical metastasis rates.展开更多

For advanced gastric cancer (AGC), neoadjuvant chemotherapy (NAC) can reduce its stage, increase the rate of radical resection, improve response to treatment, reduce the risk of local recurrence and improve survival rate. Regional arterial infusion chemotherapy (RAIC) is a form of NAC that involves directly injecting chemotherapeutic drugs into the tumor site through the tumor-feeding artery. RAIC increases the local drug concentration around the tumor, thereby improving the therapeutic responses and reducing the adverse effects of the drugs. In recent years, RAIC has attracted increasing attention. This article summarizes the basic principles, procedure, chemotherapy regimens, adverse drug reactions and complications, clinical applications and response evaluation of RAIC in the treatment of AGC.展开更多

After surgical resection, the contents of PI3K/AKT/mTOR, Wnt/β-catenin and MEK/ERK signaling pathway in cervical cancer lesions were determined.Results:p-PI3K, p-AKT, mTOR, MMP2, VEGF,β-catenin, CyclinD1, Twist, Slug, Snail, MEK1, MEK2, ERK1/2 and Bcl-2 protein levels in cervical cancer lesion of intervention group were significantly lower than those of intravenous group whereas E-cadherin and Bax protein levels were significantly higher than those of intravenous group.Conclusion: Neoadjuvant interventional arterial chemotherapy can be more effective than neoadjuvant intravenous chemotherapy to inhibit the cancer cell growth mediated by PI3K/AKT/mTOR, Wnt/β-catenin and MEK/ERK signaling pathway in cervical cancer.展开更多

The aim of this research is to evaluate the clinical and pathohistological responses and effects of preoperative bronchial artery infusion (BAI) chemotherapy in patients with locally advanced (stage Ⅲ) non-small cell lung cancer (NSCLC). Methods: A total of 92 patients with locally advanced NSCLC were randomly divided into two groups. BAI group received BAI chemotherapy for 2 cycles before surgical resection. Surgery group received operation only. The complete resection rate and clinical response were compared between the two groups. Results: In the BAI group, the clinical response rate and the pathohistological response rate were 68.3% and 51.3%, respectively. The complete resection rate in the BAI group was 89.7%, which was significantly higher than that in the surgery group (72.5%) (P 〈 0.05). The 1- and 2-year survival rate was 100.0% and 80.6% in the BAI group, and 94.1% and 60.0% in the surgery group. Conclusion: BAI neoadjuvant chemotherapy is safe and effective, which has a good clinical and pathohistological response. It might increase the complete resection rate of the tumor and improve the long term survival rate of stage Ⅲ NSCLC patients.展开更多

Methods: 92 cases with locally advanced NSCLC patients were randomly divided into two groups: (1) BAI chemotherapy group: 39 cases were received BAI chemotherapy for 2 courses and followed surgery; (2) surgery alone group: 51 cases were treated by operation alone. The complete resection rate and preoperative complications were compared between these two groups. Results: In BAI chemotherapy group, the rate of clinical efficiency was 68.3% with slight toxicity. In BAI chemotherapy group the surgery complete resection rate was 89.7%, which was significantly higher than that in surgery alone group (72.5%, P 〈 0.05). No significant differences of blood loss, operative complications and mortality were observed between these two groups. Conclusion: BAI neoadjuvant chemotherapy was safe and effective, which can increase the complete resection rate of the tumor and did not increase the operative complications and mortality.展开更多

In this prospective study, the effect of multiple-phase RIAC for patients with resectable pancreatic head adenocarcinoma was evaluated, and its safety and validity comparing with postoperative RIAC were also assessed. Methods Patients with resectable pancreatic head cancer were randomly assigned to two groups. Patients in group A (n=-50) were treated with new therapeutic mode of extended pancreaticoduodenectomy combined with multiple-phase RIAC, and those in group B (n=-50) were treated with extended pancreaticoduodenectomy combined with postoperative RIAC in the same period. The feasibility, compliance and efficiency of the new therapeutic mode were evaluated by tumor size, serum tumor markers, clinical benefit response (CBR), surgical complications, mortality and toxicity of RIAC. The disease-free survival time, median survival time, incidence of liver metastasis, survival rate at 1, 2, 3 and 5 years were also observed. Life curves were generated by the Kaplan-Meier method. Results The pain relief rate and CBR in group A was 80% and 84% respectively. Serum tumor markers decreased obviously and tumors size decreased in 26% of patients after preoperative RIAC in group A. No more surgical complications, mortality or severe systemic side effects were observed in group A compared with group B. The incidence of liver metastasis in group A was 34% which was lower than 50% in group B. The disease-free survival time and median survival time in group A were 15.5 months and 18 months respectively. The 1-, 2-, 3- and 5-year survival rates were 54.87%, 34.94%, 24.51% and 12.25% respectively. There was no significant difference of survival time or survival rates between two groups. Conclusions Multiple-phase RIAC is effective in combined therapy of resectable pancreatic head carcinomas by enhancing inhibition of tumor growth and reduction of liver metastasis, without negative effect on patients' safety or surgical procedure.展开更多
