ABSTRACT
PURPOSE: We hypothesized that the vascular protecting effect of an angiotensin receptor blocker (ARB) reduced endothelial damage of the radial artery (RA) after coronary bypass and conducted a comparative study. PATIENTS AND METHODS: One hundred and sixty four patients were divided into the following two groups, Group C: 92 subjects who were orally administered Candesartan 8 mg/day, Group I: 72 subjects who were administered Imidapril at 5 mg/day. Graft angiography was performed one year after surgery and the RA intima was evaluated using an angioscope. RESULTS: Total cholesterol of Group C was 151.4+/-66.9 mg/dL, which was significantly lower than in Group I (182.2+/-27.8 mg/dL), and LDL cholesterol of the ARB-treated group, i.e., Group C was 96.1+/-32.5 mg/dL and significantly lower than in Group I (139.1+/-48.7 mg/dL). In angioscopy, yellow plaque was detected in the proximal RA in 7 (8.0%) and 8 (11.6%) patients of the Groups C and I, respectively, showing a lower tendency in the ARB-treated group. CONCLUSIONS: The results of evaluation one year after surgery revealed no significant difference in effects on the RA endothelium between ARB and ACE inhibitor. ARB reduced cholesterol and its effect was confirmed with blood examination data and endoscopic findings.

Subjects were 20 patients with tongue cancer treated between April 1996 and December 2002 with intraarterial infusion of cisplatin (60-120 mg/m2) (and docetaxel 10-30 mg/m2) and intravenous infusion of sodium thiosulfate followed by 5-fluorouracil (5-FU) (800-1000 mg/m2) for 3 to 5 days. All patients underwent radiation (50-80 Gy). Ten had stage II, 4 stage III, and 6 stage IV A disease. Complete response at the primary site was achieved in 50% for T2, 67% for T3, and 0% for T4 lesions in those undergoing IA cisplatin followed by systemic 5-FU with concurrent radiation. Complete response at the primary site was achieved in all patients given IA cisplatin and docetaxel followed by systemic 5-FU with concurrent radiation. Disease-specific survival was 75% and overall survival 69% at 5 years. Side effects of treatment were tolerable, except for grade three radiomucositis in 70% of patients and grade three bone marrow depression in one treated with weekly IA chemotherapy.

Advanced cervical cancer has been predominantly treated with a combination of external beam and brachytherapy in Japan. Recent studies suggest concurrent use of cisplatin and radiation treatment has superior disease control to radiation only treatment. We have conducted a phase I pilot study of concurrent use of weekly nedaplatin (30 mg/m2) and sequential external beam and brachytherapy in advanced stage or recurrent uterine cervical cancer patients (n = 6). All patients completed the treatment without serious complications. Five patients had complete responses and one a partial response. The average AUC of nedaplatin after one administration was 5.0 micrograms/ml.hr. The therapeutic index was 2. We concluded that concurrent use of weekly nedaplatin and radiation is well tolerated by Japanese women, and may well be an excellent therapeutic modality for selected cases of advanced or recurrent cervical cancer.
