Objective: To clarify the effect of intraarterial chemotherapy on vascular endothelial growth factor (VEGF) expres- sion and microvessel density (MVD) count in carcinoma of the cervix. Methods: Before intraarterial chemotherapy and after 2–3 weeks of therapy, the expression of VEGF and MVD count in 36 carcinoma tissues of locally advanced cervical cancer were determined by CD34. Results: Before intraarterial chemotherapy and after 2–3 weeks, the expression of VEGF were 75% (27/36) and 30.6% (11/36) respectively, and MVD were reduced obviously (P<0.001). Conclusion:?The intraarterial chemotherapy can reduce the expression of VEGF and MVD, and adjust malignancy of cervical cancer, and cut down the postoperative metastasis. 展开更多

Background Bladder cancer is the ninth most common cancer in the world; fewer than 15% of transitional-cell carcinoma patients survive 2 years if left untreated.Although radical cystectomy is the standard treatment of choice,much of them relapse and the necessity of adjuvant chemotherapy is still under debate.The aim of the study was to evaluate the efficacy of adjuvant intraarterial chemotherapy (IAC) with gemcitabine and cisplatin (GC) on locally advanced bladder cancer.Methods This is a retrospective study on 60 patients with locally advanced bladder carcinoma who underwent radical cystectomy between May 2000 and June 2011.Patients were studied in two groups based on IAC and followed up for up to 5 years.Results Among 60 patients,there were 25 patients who underwent IAC (GC) after radical cystectomy (the IAC group) and 35 patients who underwent radical cystectomy alone (the control group).Although not significant,the relapse rates were slightly reduced in the IAC group than in the control group.Patients with IAC had a reduction in mortality compared with patients without IAC over 5 years.Specifically,IAC significantly reduced about 82% of mortality within the first year (hazard ratio=0.18,95% Cl 0.03-0.97,P=-0.04).Additionally,IAC was well tolerated and safe.The most common adverse effect was transient myelosuppression (10/25,40%),which was resolved by various medical treatments.Conclusions Compared with radical cystectomy alone,radical cystectomy in combination with adjuvant IAC moderately but significantly reduces 1-year mortality.Our preliminary data showed only marginal benefit for the early survival.However,a randomized clinical study is needed to determine the long-term survival benefit. 展开更多

Objective: Through investigating the influence of neoadjuvant intraarterial infusion chemotherapy (NIAC) on the timing changes of apoptosis, PCNA and multiple drug resistance associated genes of endometrial cancer, to study the mechanism of chemotherapy and to define the best operation time. Methods: Twenty patients were subjected to neoadjuvant consecutive uterine arterial infusion with CDDP 100 mg and ADM 50 mg. The biopsy of endometrial tumor tissues was performed before, immediate after and 1, 2–2+3 w, 3+3–4 w after chemotherapy. Apoptosis index (AI) was estimated by a combination of histologic and TUNEL assays. Proliferative index (PI) was examined by SABC immunohistochemical staining. Expressions of multidrug resistance 1 (MDR1), multidrug resistance-associated protein (MRP) and lung resistance protein (LRP) were detected by reverse transcription polymerase chain reaction (RT-PCR). Results: The AI of endometrial cancer cells immediate after and 1, 2-2+3 w, after chemotherapy were 3.03%, 3.47% and 5.04%, respectively, much higher than that before chemotherapy which was 2.31%. After chemotherapy, AI/PI gradually increased. It was highest in 2-2+3 w, while 3+3-4 w after chemotherapy the AI and AI/PI were both significantly lower than that before chemotherapy. The expression of MDR1, MRP and LRP all decreased temporarily after chemotherapy, while 3+3-4 w after chemotherapy they all increased to levels higher than that before chemotherapy, but the difference were not significant (P>0.05). Conclusion: Neoadjuvant consecutive intra-arterial infusion chemotherapy via uterine artery can inhibit tumor cells proliferation and induce apoptosis effectively. To evaluate the response of intra-arterial chemotherapy the change of apoptosis index and cell proliferation should be analyzed. The most suitable time for the operation is 3 weeks after intra-arterial infusion chemotherapy. 展开更多
