[A retrospective analysis of chemotherapy for gastric cancer in later-stage elderly patients].

AIM: Despite the significant advances in chemotherapy, the prognosis of unresectable or recurrent gastric cancer is still very poor. Given that older adults are likely to have a number of concomitant diseases and an impaired major organ function, cancer chemotherapy in elderly patients requires particular caution. We examined what factors are associated with the overall survival of gastric cancer patients undergoing chemotherapy. METHODS: A retrospective chart review of gastric cancer patients receiving oral fluoropyrimidines (N=130) was performed at Nagoya Memorial Hospital over 9 years. The overall survival was calculated from the beginning of chemotherapy until death or the most recent date of follow-up. The Kaplan-Meier method was used to plot survival curves, which were compared using the log-rank test. A multivariate analysis was performed using stepwise Cox proportional hazards models. A comprehensive geriatric assessment was conducted for the elderly patients. The chart review was approved by the ethics committee of Nagoya Memorial Hospital. RESULTS: The objective response rate and overall survival did not differ markedly between the patients < 75 years (N=64) and those ≥ 75 years of age (N=28). The addition of lentinan significantly prolonged the survival of the stage 4 gastric cancer patients. In a multivariate analysis of those ≥ 75 years of age, the only independent prognostic factor for the survival was the functional capacity, as measured by the TMIG Index of Competence. CONCLUSIONS: This comprehensive geriatric assessment was useful for predicting the longevity of patients with stage 4 gastric cancer ≥ 75 years of age.

[Cooperation between a Hospital without Dentists and Local Dental Associations in Oral Management of Cancer Patients].

Severe oral mucositis induced by cancer chemotherapy can cause intolerable pain and increase the risk of systemic infections, necessitating dose reduction and discontinuation of antineoplastic agents. Moreover, this adverse effect may have an impact on patient nutrition and quality of life. An effective and prophylactic intervention should be useful for alleviating this complication. Because Nagoya Memorial Hospital has neither a dentistry nor an oral surgery department, we collaborated with dental associations near the hospital. First, we performed a questionnaire survey on the present status of the members of the local dental associations. The survey showed that 86% of the community dentists were interested in communicating with our hospital. In addition, they agreed to provide us with information on their specialty and status of amenities. In discussion with the community dentists, we decided on fax-based communication for collaboration to improve the quality of oral management in cancer patients. Three seminar series were conducted to share updated information on cancer treatment and enhance communication between the medical doctors and the dentists. Our hospital has registered 129 community dentists and enrolled 81 cancer patients in this medical and dental cooperation initiative.

[Pilot study on clinical effects of rebamipide gargle against oral mucositis induced by fluoropyrimidines].

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.

Bidirectional information sharing between Nagoya Memorial Hospital and health insurance pharmacies using a communication sheet for pharmaceutical cooperation.

BACKGROUND: We collaborated with the regional pharmaceutical associations near Nagoya Memorial Hospital and created a communication sheet for pharmaceutical cooperation between the hospital and health insurance pharmacies. METHODS: The communication sheet for pharmaceutical cooperation was issued in October 2014. We conducted a questionnaire survey of both cancer patients and community pharmacists 1 year after the implementation of the use of this sheet. Based on the results of the survey, we modified our communication sheet and added a unified reply form in October 2016. We examined the number of replies from community pharmacists from October 2014 to April 2019. We then analyzed how community pharmacists instructed and communicated with cancer patients using the results of both the questionnaire survey and the reply form, which were compared before and after introducing the modified version of the communication sheet. RESULTS: During the 5 years of observation, 743 communication sheets were sent from Nagoya Memorial Hospital to community pharmacists. As a result of pharmaceutical cooperation in using the communication sheet, 96.4% of prescribed medication were immediately prepared in health insurance pharmacies on that day. The communication sheet also enhanced the conversations between cancer patients and pharmacists. The introduction of the unified reply form increased the response rate of community pharmacists from 1.7 to 69.5% (p < 0.001). The communication between community pharmacists and cancer patients was significantly hindered by prescriptions without an oral cancer drug and patient age < 65 years old (p < 0.05). However, this hindrance was reduced by the use of the modified form. CONCLUSIONS: The communication sheet for pharmaceutical cooperation is useful for bidirectional information sharing between hospitals and health insurance pharmacies, which may enable pharmacists to provide cancer patients with medication instructions in coordination with hospitals and increase the quality of outpatient pharmacy services.

[A case of interstitial pneumonia induced by S-1/irinotecan combination therapy].

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.
