    ABSTRACT: Abstract Aim: To examine the efficacy of oral rinsing against chemotherapy-induced stomatitis. Methods: Consecutive fluoropyrimidine-treated patients with stomach and colorectal cancer were enrolled from April 2009 to March 2011 (n=43; Group 1) and from January 2012 to December 2012 (n=45; Group 2). The incidence and severity of stomatitis were compared between Group 1 patients, who were instructed to gargle with lemonflavored water 6 times daily, and Group 2 patients, who did not receive any specific guidance. Among patients in the gargle group, we determined the rate of gargling compliance as well as quality of life (QOL) scores, and evaluated the impact of rebamipide use on patient outcomes. Results: The incidence of stomatitis was significantly reduced in Group 1 (14.0%) compared to that in Group 2 (33.3%) and its severity in the former group was milder. Among patients using lemon-flavored water, concomitant rebamipide use had no statistically significant impact on stomatitis incidence (with versus without rebamipide, 19.0% versus 9.0%), the rate of gargling compliance (96.4% versus 94.2%), or QOL scores. Conclusions: Oral rinse with lemon-flavored water is useful for the symptomatic control of fluoropyrimidine induced stomatitis, regardless of the presence or absence of rebamipide.

    ABSTRACT: In Aichi Cancer Center Hospital, we investigated the incidence of injection-site reactions associated with the administration of Oxaliplatin into a peripheral vein. We evaluated the frequency and severity of symptoms, and studied ways to manage its adverse reactions from September 2009 through March 2010. Oxaliplatin was injected into a peripheral vein in more than 90% of patients, suggesting that there would be a high risk of injection-site reactions. About 60% of patients had a numeric rating score of 5 or higher in this study, and more than 60% of injection-site reactions were improved by warming the injection site. Our results suggest that warming the injection site is one effective way to manage local adverse reactions when Oxaliplatin is administered into a peripheral vein.

    ABSTRACT: Rebamipide, a cytoprotective agent, has been suspected to attenuate oral mucositis through anti-inflammatory potentials and induction of endogenous prostaglandin synthesis. This prospective study was designed to assess the clinical efficacy of rebamipide gargle against oral mucositis, which is induced by fluoropyrimidines in patients with stomach and colorectal cancer. We first conducted a pilot study on gargle flavors, because the solution in this agent has a strong and bitter after taste. Nine kinds of flavors were prepared, and six characteristics were evaluated by ten volunteers: sourness, bitterness, sweetness, remain, after taste, and hard to drink. We determined the contents of rebamipide using HPLC, which showed stability in an acidic condition. Finally, we decided that 100% Pokka Lemon should be used as the flavor of the rebamipide solution. A clinical study was then started to compare the preventive effects rebamipide gargle and placebo have on stomatitis, quality of life (QOL), and the therapeutic effects of chemotherapy.

    ABSTRACT: We prospectively analyzed the adverse effects and outcomes of 15 patients with stage IV gastric cancer who underwent palliative gastrectomy from December, 2002 to May, 2008 and subsequently received combination therapy of S-1 and 4-h infusion of cisplatin. The National Cancer Institute common toxicity criteria (version 3. 0) were applied to evaluate the adverse effects of this therapy, and the Kaplan-Meier method was used to plot the survival curve. The side effects most frequently observed were anorexia (grade 3; 33%), although one case of grade 4 who was easily fatigued was noted during the first course and could not receive further courses of this therapy. The 2-year survival rate was 33% and median survival time was 31 months. It has been suggested that 24-h infusion of cisplatin combined with oral S-1 after reduction surgery might improve survival in patients with stage IV gastric cancer.

    ABSTRACT: From July, 2007 to June, 2008, we prospectively investigated the influence of Hange-shashin-to on the therapeutic and adverse effects of chemotherapy and the changes in quality of life(QOL)scores of the patients with metastatic gastric and colorectal cancer. Twenty patients receiving S-1/Irinotecan (CPT-11) therapy were randomly allocated into group A (with Hange-shashin-to) and B (without Hange-shashin-to). While the anti-tumor effects did not differ significantly between these two groups, severe side effects of more than grade 3 occurred less frequently in group A. Our results suggested that the decrease in QOL scores on day 15 might be alleviated in group A, compared to group B. Therefore, Hange-shashin-to can be one of the useful supportive medicines in the combination therapy of S-1/CPT- 11.

    ABSTRACT: A 67-year-old man with multiple liver metastases of colonic cancer was treated with combination therapy of S-1 and irinotecan (CPT-11): S-1 (120 mg/day) administered orally for 14 consecutive days followed by 14 days rest. CPT-11 (100 mg/m(2)) was given as a 2-hour infusion on day 1 and 15. The patient complained of high fever and subsequent exertional dyspnea in the middle of the second course of S-1/CPT-11 therapy. He was hospitalized with severe hypoxemia. CT scan showed extensive ground glass and consolidative changes in bilateral lungs. Steroid pulse therapy with oxygen therapy remarkably improved his symptoms, and abnormal findings on CT scan also resolved. Drug-induced pneumonia needs to be considered in the differential diagnosis when patients treated with S-1/CPT-11 combination therapy present high fever and dyspnea.

    ABSTRACT: Oxaliplatin (L-OHP) has been established as a key drug for advanced colorectal cancer, and combination therapy with 5-FU/Leucovorin (LV)(FOLFOX regimen) is commonly used in Europe and the US. A phase I study of modified (m) FOLFOX 6 therapy was conducted to determine the recommended dose (RD) of 5-FU infused for 46 hours. Inclusion criteria were unresectable advanced colorectal cancer,measurable lesions, performance status (PS; ECOG) 0-2, age 20-75 years, and adequate organ functions. L-OHP and l-LV was administered over 2 hours and followed by bolus injection and continuous infusion of 5-FU for 46 hours every 2 weeks. Two cycles of mFOLFOX 6 therapy were performed. Doses of L-OHP, l-LV, and bolus injection of 5-FU were fixed at 85 mg/m(2), 200 mg/m(2), and 400 mg/m(2), respectively. The dose of continuous infused 5-FU was escalated from 1,600 mg/m(2), (level 1), 2,000 mg/m(2), (level 2), 2,400 mg/m(2), (level 3), and 2,800 mg/m(2), (level 4). RD was determined in a dose escalation manner, and safety was evaluated according to NCI-CTC Ver 2.0. A total of 13 patients were enrolled. Male/female=7/6, PS 0/1/2=2/4/7, mean age 64 years (range 55-75). Thrombocytopenia was not observed, and grade 2 of neutropenia and peripheral neuropathy was observed in 4 and 6 out of 13 patients. No dose-limiting toxicity (DLT) was observed at level 1 (n=3), 2 (n=4), and 3 (n=4), but at level 4 (n=2), 2 patients experienced DLT; grade 3 easy fatigue and anorexia required treatment delay over 7 days. Level 3 was therefore determined as RD. A phase II study is ongoing to evaluate the efficacy of mFOLFOX 6 therapy.
