Purpose: This study aimed to identify patient-related risk factors for chemotherapy-induced nausea and vomiting (CINV) in patients with cancer receiving carboplatin in addition to standard antiemetics, using real-world data.
Methods: In this single-center, observational study, data from electronic medical records of consecutive patients with solid tumors who had received their first cycle of a carboplatin-based regimen and were treated with a 2- or 3-drug combination of antiemetics from January 2014 to January 2019 at Toranomon Hospital were retrospectively analyzed. The primary end point was the occurrence of a complete response (CR) within 5 days after the first cycle, which was defined as no vomiting and no use of rescue medication for CINV. A receiver operating characteristic curve, univariable, and multivariable logistic regression analyses were used.
Findings: A total of 314 patients were evaluated in this study. The proportion of patients who had a CR in the overall, acute, and delayed phases was 76.8% (n = 241), 98.7% (n = 310), and 77.4% (n = 243), respectively. Similar to univariable logistic regression analysis, multivariable logistic regression analysis revealed that age ≥70 years and total dexamethasone dose ≥14.6 mg were significantly associated with a non-CR in the overall phase, whereas female sex, history of habitual alcohol intake, and history of smoking were not associated with a non-CR in the overall phase.
Implications: Our study findings suggest that a patient age of <70 years and a total dexamethasone dose of <14.6 mg are high-risk factors for carboplatin-induced CINV.

Pharmacy practice experience (PPE) is essential in the six-year course of pharmaceutical education in Japan. We previously found that PPE reinforced students' self-efficacy for curriculums (SECs), leading robust acquisition and reconstruction of pharmaceutical expertise. In this study, we aimed to clarify whether students' SECs affect successful experiences as enactive attainments in PPE. We distributed survey questionnaires to the fifth-year students in Keio University in 2016-2017 before and after PPE. The students made a self-assessment of their psychological state “expect to do well” on a seven-point Likert scale for each curriculum (C1 to C18), and their successful experiences were also collected from free description type questionnaire. We could follow up 139 students. The SEC scores increased from pre-PPE to post I (p<0.001) and II terms (p<0.01). The increase in SEC scores during PPE was associated with the rate of students' successful experiences in the first-term PPE (p=0.04). The path analysis revealed the following as significant predictive factors of SECs for successful experiences: basic sciences (C1, C2, C3, C4, C5, and C6) with stand-ardizing coefficient 0.35, health and environmental sciences (C11 and C12) with 0.39, and pharmaceutical sciences (C7, C8, C9, C10, C13, and C14) with −0.51. Students in the first-term PPE tended to experience successful performance in medical professions by using their pharmaceutical expertise that they had learned. In this study, for the first time, we demonstrated that Japanese students' SECs for pharmaceutical expertise affected successful experiences, leading better outcomes of PPE.

Screening for total pain and sharing of patient information including adverse events for patients receiving chemotherapy by medical staff is needed in clinical practice. We introduced a sharing system for patient-oriented outcome sheets via a touch panel at an outpatient chemotherapy clinic. This study aimed to assess whether the system contributes to the improved management of treatment-related adverse events. We retrospectively analyzed data from a total of 215 patients at Ehime University Hospital using their electronic medical records from April to August 2015. Forty of these patients had received interventions relating to treatment-related adverse events. The proportion of a total number of interventions before and after the sharing system was 42/282(14.9%)and 45/215(20.9%), respectively. The proportion of a total number of interventions at the first course of outpatient chemotherapy also increased from 9/40(22.5%)to 14/40(35%)compared with before the sharing system. The purpose of interventions were for insomnia, anorexia, and cancer-related pain, etc., listed in order of degree of frequency. These results suggest that a sharing system of patient-reported interview sheets contributes to tracking treatment -related adverse events and aids in ensuring interventions can be efficiently performed by multidisciplinary team members.

ゲムシタビン誘発性血管痛は末梢静脈投与で生じ、臨床上未解決のままとなっている。エピルビシンとオキサリプラチンにおける先行研究によれば、抗炎症作用とpH調整目的にデキサメタゾンがオプションとなる。本研究の目的は、先発及び後発品のゲムシタビンとデキサメタゾン配合の製剤学的安定性を調査することであった。我々はデキサメタゾン配合後の凍結乾燥製剤及び液体製剤のゲムシタビン先発及び後発品11品目の濃度、pH及び外観変化を生理食塩液及び5%ブドウ糖液希釈において24時間後まで評価した。濃度とpHはそれぞれ高速液体クロマトグラフィーとpHメータで測定した。配合液の濃度及びpHは生理食塩液及び5%ブドウ糖液希釈において24時間後まで変化しなかった。ゲムシタビンの液体製剤のpHは凍結乾燥製剤と比較して、生理食塩液及び5%ブドウ糖液希釈においてわずかに低かった。さらに、生理食塩液及び5%ブドウ糖液希釈において外観変化はなかった。これらの結果は、すべての先発及び後発品のゲムシタビンの製剤学的安定性はデキサメタゾン配合によって影響を受けなかった。本研究は、実臨床においてゲムシタビン誘発性血管痛の可能性を減らすために、先発及び後発品のゲムシタビンはデキサメタゾンと配合投与できることを示唆する。(著者抄録)

Purpose: Venous pain induced by peripheral intravenous infusion of gemcitabine has remained an unresolved issue in clinical practice. This study aimed to identify differences between gemcitabine formulations as well as risk factors associated with gemcitabine-induced venous pain in patients with cancer.
Methods: We retrospectively analyzed data from consecutive patients with cancer who had received chemotherapy including a lyophilized or liquid formulation of gemcitabine diluted with 5% glucose solution via a peripheral vein. The study was conducted at Ehime University Hospital using electronic medical records dated between January 2015 and July 2017. The primary end point was the prevalence of venous pain at the administration site during gemcitabine infusion, classified as injection site reaction of grade ≥2 according to the Common Terminology Criteria for Adverse Events, version 4.0. A multivariate logistic regression analysis with generalized estimating equations for longitudinal data was used to identify risk factors for venous pain during all courses of gemcitabine treatment.
Findings: A total of 1150 treatment courses in 141 Japanese patients were evaluated in this study. Venous pain occurred in 115 courses (10.0%) and in 49 patients (34.8%). The multivariate logistic regression analysis with generalized estimating equations revealed that a dose increase of gemcitabine and use of the liquid formulation of gemcitabine were significantly associated with an increased risk for venous pain (dose increase, adjusted odds ratio [OR] = 1.25; 95% CI, 1.11–1.40 [P < 0.001]; and liquid formulation, adjusted OR = 12.43, 95% CI, 5.61–27.51 [P < 0.001]), whereas age, course number of gemcitabine, and use of the soft-back product of 5% glucose solution were significantly associated with a reduced risk for venous pain (age, adjusted OR = 0.75; 95% CI, 0.57–0.98 [P = 0.037]; course number, adjusted OR = 0.96; 95% CI, 0.92–0.99 [P = 0.023]; and soft back, adjusted OR = 0.39; 95% CI, 0.21–0.74 [P = 0.004]).
Implications: The use of the liquid formulation of gemcitabine was associated with a significant increase in the frequency of gemcitabine-induced venous pain despite dilution with 5% glucose solution compared to that with the lyophilized formulation. The lyophilized formulation of gemcitabine should hence be used in peripheral intravenous infusion for the treatment of patients with cancer.

© 2019 The Authors. The Oncologist published by Wiley Periodicals, Inc. on behalf of AlphaMed Press. Background: We previously reported the results of a prospective study of chemotherapy-induced nausea and vomiting (CINV) in a cohort of patients who received carboplatin-based chemotherapy and were selected from a nationwide registry of those scheduled for moderately (MEC) or highly emetogenic chemotherapy (HEC) by the CINV Study Group of Japan. Of 1,910 previously registered patients (HEC: 1,195; MEC: 715), 400 patients received carboplatin-based chemotherapy. The frequency of CINV was determined, and the risk factors for CINV were assessed. Materials and Methods: CINV data were collected from 7-day diaries. Risk factors for CINV were identified using logistic regression models. Results: Of 400 patients scheduled for carboplatin-based chemotherapy, 267 patients received two antiemetics (5-hydroxytryptamine-3 receptor antagonist [5-HT3 RA] and dexamethasone [DEX]), 118 patients received three antiemetics (5-HT3 RA, DEX, and neurokinin-1 receptor antagonist [NK1 RA]), and 15 were nonadherent to the treatment. In these patients, the CINV overall, acute, and delayed phase rates of complete response (CR), defined as no vomiting with no rescue medication, were 67.0%, 98.2%, and 67.5%, respectively. The rates of no nausea were 55.6%, 94.0%, and 56.1%, respectively, and those of no vomiting were 81.3%, 99.0%, and 81.8%, respectively. Older age was associated with a decreased non-CR, whereas female sex, history of pregnancy-related emesis, and dual antiemetic therapy were associated with an increased non-CR during the overall period. Conclusion: In a clinical practice setting, in patients who received carboplatin-based chemotherapy, adherence is quite high and appropriate antiemetic prophylaxis requires a triple antiemetic regimen including NK1 RA. Implications for Practice: For patients receiving carboplatin-based chemotherapy, triple antiemetic therapy with 5-hydroxytryptamine-3 receptor antagonist, dexamethasone, and neurokinin-1 receptor antagonist should be given prophylactically regardless of risk factor status.

To prepare for a new practical training scheme starting in 2019 based on a revised-model core curriculum for pharmaceutical education that incorporates outcome-based education, rubric-based assessment of student performance was implemented in practical training between May and July of 2018. The goals were to evaluate the rubric-based assessment to identify ways to improve it for appraising pharmaceutical students. All fifth-year students of the Keio University Faculty of Pharmacy in 2018 (n = 160) self-assessed their performance during practical training using evaluation sheets in a rubric form comprising three general instructional objectives with 10 task descriptions developed by the Japanese Pharmaceutical Association or Japanese Society of Hospital Pharmacists. Compared to the commencement of the training, the median evaluations in all tasks significantly increased at the completion of the practical training in the community pharmacy and the hospital settings. Survey questionnaires were administered to the students after the practical training. Customer satisfaction analysis identified two main areas for improvement of the rubric-based assessment for student growth: (1) students' lack of understanding of the rubric-based assessment in hospitals and (2) mentors' lack of understanding of it in both settings. The results suggest that rubric-based assessment is a feasible method for assessing pharmaceutical student performance during practical training. Additionally, the Faculty of Pharmacy should provide and disseminate information to students and mentors about rubric-based assessment and support mentors' efforts for student progress during practical training.

© 2018 Elsevier Inc. Purpose: Nivolumab, an anti–programmed death 1 antibody, produces antitumor effects by activating host immunity, which also causes immune-related adverse events (irAEs). The aim of this study was to analyze the association between antitumor effect and irAEs induced by nivolumab in patients with melanoma. Methods: Fifteen patients with melanoma who had received nivolumab at Tokushima University Hospital or Ehime University Hospital between January 2015 and December 2016 were enrolled in this study. Patients who had and did not have irAEs during nivolumab treatment were classified into an irAEs-positive group (n = 8) and an irAEs-negative group (n = 7), respectively. We compared the disease control rate (DCR) and overall survival (OS) between the 2 groups. Data on blood cell counts were also analyzed. Findings: After a median of 4 cycles of nivolumab treatment, irAEs occurred. The DCRs were 75% and 14% in the irAEs-positive and irAEs-negative groups, respectively (p < 0.05). OS in the irAEs-positive group was higher than that in the irAEs-negative group (p < 0.05). Multivariable Cox proportional hazards regression analysis revealed that irAE occurrence affected OS with nivolumab treatment. Moreover, the increase in baseline peripheral lymphocyte count at the time of onset of irAEs was significantly greater in the irAEs-positive group than in the irAEs-negative group after 4 cycles of nivolumab treatment (p < 0.05). Implications: Our study indicated that clinical response with nivolumab treatment improves with irAE occurrence in patients with melanoma. Moreover, the early increase in peripheral lymphocyte count may act as a biomarker for predicting the occurrence of irAEs induced by nivolumab.

© 2018 Elsevier Inc. Purpose: The aim of this study was to identify a high-risk or low-risk population for chemotherapy-induced nausea and vomiting among patients with breast cancer treated with a current standard 3-drug antiemetic regimen and receiving anthracycline. Methods: We analyzed data from chemotherapy-naive Japanese patients with breast cancer, who had received the first cycle of anthracycline-based regimen and were treated with a 3-drug combination of aprepitant, palonosetron, and dexamethasone. This study was carried out at Ehime University Hospital (Toon, Japan) using electronic medical records from May 2011 to June 2017. The primary end point was complete response (CR), which was defined as no emesis and no use of rescue medication. Findings: A total of 103 patients were included in this study. The percentages of patients who had a CR in the overall, acute, and delayed phases were 35.0%, 40.8%, and 50.5%, respectively. Multivariate logistic regression analysis revealed that age <55 years and body mass index <27.5 kg/m2 were significantly associated with an increased risk for CR failure in the overall and acute phases. In contrast, a history of alcohol habit was significantly associated with a decreased risk for CR failure in overall phase. Implications: The present findings suggest that, among patients with breast cancer receiving anthracycline and treated with aprepitant, palonosetron, and dexamethasone, patients younger than 55 years and having a body mass index <27.5 kg/m2 are high-risk populations for chemotherapy-induced nausea and vomiting, whereas those with a history of habitual alcohol consumption is a low-risk one.

© 2018, The Author(s). This study aimed to compare the antiemetic efficacy and safety of a four-drug combination with those of a standard three-drug combination in Japanese patients with breast cancer treated with anthracycline. We retrospectively analyzed data from Japanese patients with breast cancer, who had received their first cycle of anthracycline and were treated with aprepitant, palonosetron, and dexamethasone with or without olanzapine. This retrospective observational study was performed at Ehime University Hospital using the electronic medical records. Multivariable and propensity score-adjusted analyses were performed to compare the onset of complete response (CR) failure between the groups. One-hundred and thirty patients were included in this study and the four- and three-drug group had 22 and 108 patients, respectively. Similar to multivariable logistic regression analysis, propensity-adjusted logistic regression analysis revealed that the four-drug group was markedly associated with a decreased odds of CR failure in the overall, acute, and delayed phases (odds ratio [OR]: 0.27, 95% confidence interval [CI]: 0.10–0.73; OR: 0.28, 95% CI: 0.10–0.76; and OR: 0.15, 95% CI: 0.04–0.57, respectively). Additionally, treatment-related adverse events were well tolerated in both the groups. These findings suggest that the antiemetic efficacy of the four-drug combination is superior to that of the standard three-drug combination.

© 2018 Elsevier Inc. Purpose: Oxaliplatin-induced peripheral neuropathy has remained an unresolved issue in clinical practice. Our previous study hypothesized that inhibition of the renin-angiotensin system (RAS) may produce a preventive effect on oxaliplatin-induced neuropathy. The aim of this study was to clarify whether RAS inhibitors prevent oxaliplatin-induced peripheral neuropathy. Methods: This study retrospectively analyzed data from cancer patients who had received chemotherapy including oxaliplatin and were treated with or without RAS inhibitors. This retrospective observational study was conducted at Ehime University Hospital using electronic medical records from May 2009 to December 2016. The primary end point was the incidence of severe peripheral neuropathy during or after oxaliplatin treatment, according to the Common Terminology Criteria for Adverse Events, version 4.0. A multivariate Cox proportional hazards model analysis was used to identify risk factors. Findings: A total of 150 patients were included in the study. The estimated incidence of peripheral neuropathy was 36.9% and 91.7% in the RAS inhibitor group and the non–RAS inhibitor group, respectively. The multivariate analysis using a Cox proportional hazards model showed that the RAS inhibitor group was slightly associated with a decreased risk of neurotoxicity (adjusted hazard ratio, 0.42 [95% CI, 0.18–0.99]; P = 0.048). Implications: The present findings suggest that RAS inhibitors have the ability to prevent oxaliplatin-induced peripheral neuropathy.

© 2017 Background: The prognosis of diffuse large B-cell lymphoma (DLBCL) is remarkably improved after R-CHOP therapy. However, there are few detailed reports regarding very elderly DLBCL patients. We investigated relationships between prognostic factors and mortality risk in DLBCL patients, especially those aged 80 years or more. Methods: The study subjects consisted of 141 patients newly-diagnosed with de novo DLBCL. Information regarding age, sex, stage, performance status (PS), lactate dehydrogenase (LDH), extranodal (EN) involvement, and therapies was available. Results: For the 141 patients, the female sex was significantly inversely related to mortality, whereas age ≥80 years, PS ≥2, and non-standard therapy were significantly positively associated with death. No associations were observed between death and stage, LDH, or EN. When classifying patients by age (<80 [n = 108] and ≥80 [n = 33] years), a significant inverse association between female sex and mortality was found only in the latter (very elderly) group. Positive relationships of PS ≥2 with mortality was more pronounced in patients ≥80 years of age than in those <80 years of age. A significant positive relationship with non-standard therapy was found only in patients <80 years of age. Conclusion: PS ≥2 may be positively associated with mortality, regardless of age. Female sex may be inversely related to mortality only in DLBCL patients aged 80 years or more, possibly due to the difference in rituximab clearance between the two study groups.

A Japanese guideline for the safe handling of anticancer drugs recommends a closed system drug transfer device (CSTD). We gradually introduced the PhaSealTM system from preparation to administration of all anticancer drugs to inpatients on holidays as well as weekdays. We evaluated whether the CSTD handling of 36 pharmacists was appropriate or not and also retrospectively compared outcomes before and after the introduction of CSTD. In nine pharmacists who had more than 4 items of an inappropriate handling of CSTD, the median noncompliance ratio after re-training was significantly improved from 4 to 1 items (P = 0.008). We subsequently administered a questionnaire for 36 pharmacists. The customer satisfaction analysis indicated two issues for improvement: anxiety over appropriate preparation on the double audit system of pharmacists and anxiety over miss priming after liquid sensor. On the other hand, the median introduction ratio per day of CSTD between February and April 2016 and between September and October 2016 was significantly increased on weekdays and holidays (P < 0.001 and P < 0.001, respectively). In addition, the median preparation time per day between February and April 2016 and between September and October 2016 was not significantly increased on weekdays and holidays (P = 0.514 and P = 0.423, respectively). These results suggest that our training for pharmacists contributed to an appropriate handling of CSTD, resulting in the safe handling of all anticancer drugs to inpatients on weekdays as well as holidays and the risk management of pharmacists without increase of the preparation time.

Background Venous pain induced by peripheral intravenous administration of oxaliplatin remains clinically unresolved. Objective The aim of this study was to determine the efficacy of comprehensive intervention care for venous pain in colorectal cancer patients receiving oxaliplatin. Setting A Japanese tertiary hospital. Method We treated all outpatients after April 2012 with comprehensive intervention care including pre-warming of the oxaliplatin solution, use of a hot compress, and pH adjustment by combination with dexamethasone. We retrospectively reviewed the electronic medical records from colorectal cancer patients who had received oxaliplatin via a peripheral vein between December 2009 and June 2014. Main outcome measures The primary endpoint of this study was the incidence of venous pain at the administration site during oxaliplatin infusion, according to injection site reaction grade ≥ 2. Results We evaluated 271 treatment courses in 59 patients. Venous pain occurred in 42 courses (15.5%) among 26 patients. Multivariate logistic regression analysis revealed that female gender and body mass index ≥ 25 kg/m2 were significantly associated with an increased risk of venous pain during all courses (adjusted odds ratio [OR]: 3.18, 95% confidence interval [CI] 1.35–7.92; P < 0.01; and adjusted OR: 3.37, 95% CI 1.26–9.40; P = 0.02, respectively), whereas comprehensive intervention care were significantly associated with reduced risk of venous pain during all courses (adjusted OR: 0.10, 95% CI 0.02–0.44; P < 0.01). Conclusion Comprehensive intervention care is a clinical treatment option for oxaliplatin-induced peripheral venous pain in patients with colorectal cancer, especially females with obesity.

Treatment with antipsychotic drugs has been associated with hyperprolactinemia. The same antipsychotic drugs have also been associated with side effects such as menstruation disorders. The aim of this study was to evaluate the prevalence of hyperprolactinemia and menstruation disorders in women undergoing antipsychotic treatment. We performed a retrospective chart review study of psychiatric patients who underwent laboratory testing for serum prolactin (PRL) level between March 2011 and March 2015 in Ehime University Hospital. Patients presenting with and without menstruation disorders were evaluated to determine if they presented concomitant hyperprolactinemia. Patients with menstrual disorders had a significant increase in serum PRL level with a mean of approximately 90 ng/mL. Those with menstrual disorders presented increased PRL levels by 2-fold that of patients without menstrual disorder. However, there was no significant difference in the equivalent dose of chlorpromazine between these two groups. Additionally, about 70% of patients with menstrual disorders received risperidone treatment. The receiver operating characteristic curve showed that the optimal cutoff point of serum PRL level associated with the development of menstrual disorders was 60 ng/mL. Based on these results, we concluded that patients with menstrual disorders presented increased serum PRL, and that most of them underwent treatment with risperidone.

Purpose: The therapeutic benefit of a three-drug combination of antiemetics has not been established in moderately emetogenic chemotherapy (MEC). The aim of this study was to compare the antiemetic effectiveness and cost-saving of palonosetron plus dexamethasone (control group) with aprepitant, granisetron, and dexamethasone (study group) in cancer patients who received MEC.
Methods: We switched the standard antiemetic treatment from the control group to the study group in gastrointestinal cancer patients who received MEC after October 2015. The antiemetics in both groups were modified using salvage antiemetic therapy at the clinicians' discretion, according to the severity of chemotherapy-induced nausea and vomiting. We retrospectively reviewed the electronic medical records from patients, before and after switching groups, from between April 2014 and March 2016.
Results: We evaluated 443 treatment courses in 83 patients. The proportion of courses that included salvage antiemetic therapy in the control group and the study group was 34.8 % (116/333) and 8.2 % (9/110), respectively, and was statistically significant (p < 0.001). The mean integrated costs of antiemetics per course in the control group and the study group were 193 ± 55 USD and 143 ± 38 USD, respectively. Multivariate logistic regression analysis revealed that the study group was significantly associated with a reduced risk of requiring salvage antiemetic therapy (p = 0.038).
Conclusions: These results suggest that the antiemetic effectiveness and cost-saving of a three-drug combination of aprepitant, generic granisetron, and dexamethasone was superior to a two-drug combination of palonosetron plus dexamethasone in gastrointestinal cancer patients who received MEC.
