We made the fusion image of both stent and platinum coil after embolization of an unruptured aneurysm. After scanning with cone beam computed tomography, we made three dimensional (3D) images of stent and coil and fused them. We can evaluate unruptured aneurysm after embolization by using a fusion image. 3D-fusion image is useful on clinical cases. Source

Background: Breakthrough cancer pain typically has a rapid onset and relatively short duration. Due to this temporal profile, it may not be adequately relieved by oral opioid analgesics. The sublingual fentanyl orally disintegrating tablet is a formulation by which fentanyl can be rapidly absorbed across the oral mucosa producing rapid-onset analgesia, and which may be effective for breakthrough pain treatment. Methods: A multicenter, randomized, placebo-controlled, double-blind comparative study was conducted to evaluate the efficacy and safety of the sublingual fentanyl tablet at optimized doses for breakthrough pain treatment in cancer patients treated with strong opioid analgesics at fixed intervals. The optimal dose was determined by open-label dose titration. The efficacy and safety of a 12-week extended treatment were also evaluated. Results: Eleven of 42 subjects who received the sublingual fentanyl tablet experienced adverse drug reactions. Common reactions were somnolence, constipation, nausea, and vomiting. No serious adverse reactions occurred. Sublingual fentanyl tablets at optimal doses and placebo were administered to 37 subjects in a double-blinded manner. A significant analgesic effect of the sublingual fentanyl tablet was present compared to placebo at 30 min after administration. The sublingual fentanyl tablet was also effective and safe during extended treatment, in which changes in basal opioid doses as well as sublingual fentanyl tablet doses were made as needed. Conclusion: Sublingual fentanyl tablets at doses determined by titration were effective and safe for breakthrough pain treatment in cancer patients treated with strong opioid analgesics at fixed intervals. Extended treatment up to 12 weeks was also effective and safe. © 2014, Japan Society of Clinical Oncology. Source

Background: We evaluated the efficacy and safety of single-dose fosaprepitant in combination with intravenous granisetron and dexamethasone. Patients and methods: Patients receiving chemotherapy including cisplatin (≥70 mg/m. 2) were eligible. A total of 347 patients (21% had received cisplatin with vomiting) were enrolled in this trial to receive the fosaprepitant regimen (fosaprepitant 150 mg, intravenous, on day 1 in combination with granisetron, 40 μg/kg, intravenous, on day 1 and dexamethasone, intravenous, on days 1-3) or the control regimen (placebo plus intravenous granisetron and dexamethasone). The primary end point was the percentage of patients who had a complete response (no emesis and no rescue therapy) over the entire treatment course (0-120 h). Results: The percentage of patients with a complete response was significantly higher in the fosaprepitant group than in the control group (64% versus 47%, P = 0.0015). The fosaprepitant regimen was more effective than the control regimen in both the acute (0-24 h postchemotherapy) phase (94% versus 81%, P = 0.0006) and the delayed (24-120 h postchemotherapy) phase (65% versus 49%, P = 0.0025). Conclusions: Single-dose fosaprepitant used in combination with granisetron and dexamethasone was well-tolerated and effective in preventing chemotherapy-induced nausea and vomiting in patients receiving highly emetogenic cancer chemotherapy, including high-dose cisplatin. © The Author 2012.

Background: A previous randomized phase II study demonstrated that the addition of a c-Met inhibitor tivantinib to an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor erlotinib might prolong progression-free survival (PFS) in patients with previously treated, nonsquamous nonsmall-cell lung cancer (NSCLC). On a subset analysis, the survival benefit was greater in patients with wild-type EGFR (WT-EGFR) than in those with activating EGFR mutations. Herein, this phase III study compared overall survival (OS) between Asian nonsquamous NSCLC patients with WT-EGFR who received erlotinib plus tivantinib (tivantinib group) or erlotinib plus placebo (placebo group). Methods: A total of 460 NSCLC patients were planned to be randomized to the tivantinib or placebo group. Primary end point was OS. Secondary end points were PFS, tumor response, and safety. Tissue was collected for biomarker analysis, including c-Met and HGF expression. Results: Enrollment was stopped when 307 patients were randomized, following the Safety Review Committee's recommendation based on an imbalance in the interstitial lung disease (ILD) incidence between the groups. ILD developed in 14 patients (3 deaths) and 6 patients (0 deaths) in the tivantinib and the placebo groups, respectively. In the enrolled patients, median OS was 12.7 and 11.1 months in the tivantinib and the placebo groups, respectively [hazard ratio (HR) = 0.891, P = 0.427]. Median PFS was 2.9 and 2.0 months in the tivantinib and the placebo groups, respectively (HR = 0.719, P = 0.019). The commonly observed grade ≥ 3 adverse events in the tivantinib group were neutropenia (24.3%), leukopenia (18.4%), febrile neutropenia (13.8%), and anemia (13.2%). Conclusions: This study was prematurely terminated due to the increased ILD incidence in the tivantinib group. Although this study lacked statistical power because of the premature termination and did not demonstrate an improvement in OS, our results suggest that tivantinib plus erlotinib might improve PFS than erlotinib alone in nonsquamous NSCLC patients with WT-EGFR. © The Author 2015.

Introduction: The epidermal growth factor receptor (EGFR) tyrosine-kinase inhibitor erlotinib is associated with survival benefits in patients with EGFR mutation-positive non-small-cell lung cancer (NSCLC). This phase II, single-arm study examined the efficacy and safety of first-line erlotinib in Japanese patients with EGFR mutation-positive NSCLC. Methods: Eligible patients received erlotinib 150. mg/day until disease progression or unacceptable toxicity. The primary endpoints were progression-free survival (PFS) and safety. Results: A high degree of concordance was observed between different mutation testing methodologies, suggesting feasibility of early, rapid detection of EGFR mutations. Median PFS was 11.8 months (95% confidence interval [CI]: 9.7-15.3) at data cut-off (1 June 2012) (n= 102). Exon 19 deletions seemed to be associated with longer PFS compared with L858R mutations; T790M mutations were tentatively linked with shorter PFS. The safety profile was as expected: rash (any grade; 83%) and diarrhea (any grade; 81%) were most common. Six interstitial lung disease (ILD)-like cases were reported, and 5 were confirmed as ILD-like events by the extramural committee. Two patients died of treatment-related pneumonitis (JAPIC Clinical Trials Information number: Japic CTI-101085). Conclusion: Erlotinib should be considered for first-line treatment in this subset of Japanese patients, with close monitoring for ILD-like events. © 2013 The Authors. Source
