Skin disorder management in oral anticancer drugs by collaboration of hospital pharmacists and community pharmacists.

BACKGROUND: In Japan, the multidisciplinary team approach in cancer chemotherapy has become quite widespread. However, patients treated with oral anticancer drugs in outpatient clinics usually receive short medical examinations from doctors without any intervention of pharmacists. To improve this medical circumstance, we made a skin disorder manual for community pharmacists and evaluated its feasibility. METHODS: Patients who underwent oral skin toxic chemotherapy from May 1, 2017, to October 31, 2017, were enrolled. The severity of skin toxicities was evaluated based on NCI-CTCAE ver4.0. Skin care and skin disorders were assessed by community pharmacists based on the assessment document arranged by the investigator. Numbers of patients who replied to the assessment, numbers of replies, numbers of assessments and instructions for skin care, and numbers of prescription proposals were evaluated to assess the value of intervention of community pharmacists. RESULTS: Sixty-two patients were enrolled in this study. Community pharmacy responded to 55 patients (88.7%), for a total of 335 replies. The data described in the replies were as follows: 317 assessments of skin disorders (94.6%), 307 assessments of skin care (91.6%), 248 instructions for skin care (74%), and 19 prescription proposals (5.7%). CONCLUSIONS: Community pharmacists have high motivation for prevention and early detection of skin disorders. Although the number of prescription proposals is small, some proposals have contributed to improving side effects. Collaboration of hospital pharmacists and community pharmacists is important for prevention, early detection, and treatment of skin disorders caused by oral anticancer drugs.

11ß-hydroxysteroid dehydrogenase type 1 is associated with antiretroviral therapy-induced increase in low-density lipoprotein cholesterol
.

OBJECTIVE: To investigate the association between 11ß-hydroxysteroid dehydrogenase type 1 (11ß-HSD1) activity and antiretroviral therapy (ART)-induced increase in low-density lipoprotein cholesterol (LDL). MATERIALS AND METHODS: We enrolled 62 patients and used liquid chromatography-tandem mass spectrometry to measure 11ß-HSD1 activity, which was expressed as a ratio of the sum of urinary tetrahydrocortisol and allo-tetrahydrocortisol concentrations to urinary tetrahydrocortisone concentration. Patient data, including baseline laboratory values, were extracted from medical records for logistic regression analyses of factors associated with LDL increase during ART. The cutoff 11ß-HSD1 activity ratio associated with the LDL increase during ART was determined using receiver operator characteristic (ROC) curve analysis. RESULTS: The LDL level increased significantly from 88.8 mg/dL before ART to 106.7 mg/dL during ART (p = 0.04). Additionally, patients with increased LDL tended to have a higher 11ß-HSD1 activity ratio (1.59 vs. 1.21, p = 0.06) and longer duration of ART (13.9 vs. 10.2 months, p = 0.07) than patients with unchanged or decreased LDL. The cutoff 11ß-HSD1 activity ratio was 1.226. Results of the univariate logistic regression analysis suggested that 11ß-HSD1 activity ratio ≥ 1.226 was associated with LDL increase during ART (p = 0.011), with an odds ratio of 8.000. CONCLUSION: This study revealed the possible association between 11ß-HSD1 activity and ART-induced LDL increase. The findings of this study suggest that 11ß-HSD1 could be a useful drug target for the treatment of ART-induced hyperlipidemia.

Both high and low plasma glutamine levels predict mortality in critically ill patients.

PURPOSE: Plasma amino acids are important indicators for understanding human kinetics and amino acid dynamics. We aimed to investigate the association between the plasma glutamine levels and the mortality rates and determine whether plasma glutamine can predict the prognosis of critically ill patients. METHODS: The clinical records of adult patients who were admitted to an ICU were retrospectively evaluated to investigate the plasma levels of amino acids, including glutamine. RESULTS: Two hundred fourteen patients were included in this study (male, 62%; median age, 64 years; range 20-97 years). The patients' diagnoses included sepsis (45%), trauma (14%), cardiovascular disease (9%), fulminant hepatitis (9%), burns (4%), and others (19%). The mortality rates in patients with plasma glutamine <400 nmol/mL (group L; 39%, 28/71) or ≥700 nmol/mL (group H; 50%, 15/30) were significantly higher (p < 0.05 and p < 0.01, respectively) than those in patients with plasma glutamine levels of 400-700 nmol/mL (group M; 21%, 24/113). Among patients with sepsis, the mortality rates of group L (46%) and group H (67%) were significantly higher (p < 0.05 or p < 0.01, respectively) in comparison with group M (26%). CONCLUSION: Both lower and higher plasma glutamine levels were risk factors for mortality in critically ill patients.

Weight Loss Associated with Platinum-Based Chemotherapy in Patients with Advanced Lung Cancer.

BACKGROUND: We examined whether the weight loss that occurs with platinum-based chemotherapy in lung cancer patients is associated with chemotherapy side effects, treatment completion rates and therapeutic effect. METHODS: We retrospectively reviewed charts of advanced lung cancer patients treated with ≥2 cycles of platinum-based chemotherapy. Patients were divided into 2 groups based on ≥5 or <5% weight loss. Relationships between weight loss and other variables were investigated. RESULTS: Among 114 patients, 18 (15.8%) experienced ≥5% weight loss. Significantly more patients with small-cell lung cancer (SCLC) than with non-SCLC were found to have ≥5% weight loss (30.8 vs. 11.4%, p = 0.023). Patients with ≥5% weight loss experienced higher incidences of grade 3-4 leukopenia (p = 0.008) and neutropenia (p = 0.005), and treatment completion rates were lower in this group (p = 0.035). Weight loss was not significantly associated with therapeutic effect. CONCLUSION: The weight loss in patients with advanced lung cancer receiving platinum-based chemotherapy is associated with SCLC, grade 3-4 leukopenia, neutropenia and a decrease in treatment completion rate.

Risk factors for cytarabine-induced cutaneous toxicity in patients with haematological malignancies.

BACKGROUND: The risk factors for cytarabine (Ara-C)-induced cutaneous toxicity are unclear. METHODS: We retrospectively reviewed the medical charts of patients with haematopoietic malignancies treated with Ara-C and examined risk factors for Ara-C-induced cutaneous toxicity. RESULTS: We reviewed 114 patients (76 men, 38 women) and found that 47 patients (41.2%) experienced cutaneous toxicity. In 93 patients (81.6%) with non-Hodgkin's lymphoma (NHL) and acute myeloid leukaemia (AML), the toxicity was significantly associated with the cancer type [AML/NHL: odds ratio (OR) = 4.84; 95% confidence interval (CI) = 1.99-11.81; p = 0.001], age (<50/≥50 years: OR = 2.54; 95% CI = 1.08-5.95; p = 0.032) and concurrent steroid administration (yes/no: OR = 0.22; 95% CI = 0.09-0.56; p = 0.001). AML was the only significant association (OR = 3.83; 95% CI = 1.21-12.06; p = 0.022) in the multivariate logistic analysis. CONCLUSION: AML, age <50 years and no steroid use are considered to be risk factors for Ara-C-induced cutaneous toxicity.

[Effect of the administration of zoledronic acid on life expectancy in patients with multiple myeloma with or without renal impairment].

Zoledronic acid(ZA)is believed to exert anticancer effects in patients with multiple myeloma(MM). For patients with impaired renal function, its dosage should be determined according to creatinine clearance(Ccr). However, there is no reported difference in life expectancy improvement between those with and without renal impairment. Therefore, we conducted a retrospective study to investigate this clinical question. Seventy-eight MM patients receiving ZA injections were selected and divided into 2 groups: (1)normal group(n=39), baseline Ccr≥60mL/min, and(2)impaired group(n=39), baseline Ccr<60mL/min. Patients in the normal group received a significantly higher initial dose(p<0.001), were of a younger age(p<0.001), had lower b2-microglobulin(b2-M)levels(p<0.001), and had higher rates of prior hematopoietic stem cell transplantation(p<0.001)than those in the impaired group. We then compared the survival rate between 31 patients in the normal group and 27 patients in the impaired group whose treatment outcome data were available and found no significant difference(p=0.251). Therefore, our results suggest that the survival rate on ZA administration may not differ between MM patients with and without renal impairment.

Methicillin-resistant Staphylococcus aureus bacteremia at a university hospital in Japan.

Methicillin-resistant Staphylococcus aureus (MRSA) has become a leading cause of infections in hospitals, and mortality from MRSA bacteremia is high. In this study, we assessed the clinical characteristics and optimum management of 115 patients with MRSA bacteremia who were admitted to Osaka University Hospital between January 2006 and December 2010. Sixty-nine of the patients survived and 46 died of heart failure or renal failure. The nonsurvivors had reduced levels of platelets and albumin, and increased aspartate aminotransferase, total bilirubin, blood urea nitrogen, and creatinine levels. Other causes of death included sepsis, septic shock plus respiratory failure, disseminated intravascular coagulation, and unknown causes. However, a significant number of those whose infections were catheter-derived survived. Nonsurvivors were more often administered catecholamines and consultation with an infection-control team (ICT) was significantly associated with improved survival. Patients about whom the ICT were consulted were administered significantly more additional anti-MRSA drugs, for example trimethoprim-sulfamethoxazole, clindamycin, and gentamycin, than patients who were not the subject of consultation, although trough values for vancomycin did not differ between the two groups. Catheter removal was significantly higher for surviving patients with severe or complicated infections. These results suggest the status of patients with MRSA bacteremia who did not survive was worse than those who did survive, but that ICT consultation might significantly affect survival by recommendation of appropriate care and anti-MRSA drug use.

Light-induced deterioration test of carboplatin under clinical settings.

Chemotherapeutic drug dosages are calculated precisely based on the patient's height, body weight, and renal function, etc. To ensure safe and favorable outcomes of treatment, dosing solutions are prepared by appropriate mixing of the drug solutions based on such calculations. The package inserts for many injectable preparations include a warning for storing the product "shielded from light." However, there are no reports of stability assessment of a mixed product against light exposure or the residual amount of active ingredient in the dosing solution during or at the end of treatment. We evaluated the stability of carboplatin from the time of mixing of the dosing solution until the end of drug infusion in a clinical-like setting. With 4-hour exposure to outdoor scattered light, the dosing solution began to show discoloration by 1 hour, becoming dark yellow by 4 hours, with reduction of the percent residual carboplatin to about 23%. To identify the optimal light-shielding shade, the dosing solution was shielded from outdoor scattered light with 1 of 3 protective covers: aluminum foil, yellow plastic shade, and brown plastic shade. The yellow plastic shade prevented any changes of the appearance of the dosing solution during the 4-hour exposure period. The percent residual carboplatin, determined by HPLC, in the dosing solution shielded with a yellow plastic shade was about 85.2% at 2 hours and 78.6% at 4 hours. Thus carboplatin dosing solution should be completely shielded from light until infusion is completed.

[Global Standards for Pharmaceutical Education].

The environment surrounding clinical pharmacy practices has changed greatly in the past thirty-some years, basically since the end of the 1980s. During this period, the separation ratio between pharmacists' dispensing and prescribing functions has increased, from 12% to 74%. The three big events in this timeline include the beginning of pharmaceutical care for inpatients by hospital pharmacists in 1988; the transition of pharmacy schools to a six-year educational program in 2006; and the revision of Pharmaceutical Affairs Law, as well as its name change, in 2014. In concert with these events, the central role of the pharmacist has changed from being dispensing-centric to an active participation in patient treatment via medication as a member of the medical care team. As a key participant in these changes, the author helped to improve the operations of hospital pharmacists, strengthened their role with advanced information and communication technology (ICT) support, and established a baseline for clinical pharmacy research and education. Accordingly, in this paper, the history of this development will be reviewed, and the future of a global standard for pharmaceutical education will be discussed.

The Adequateness of Methadone for Japanese Terminal Cancer Patients Can Be Determined Earlier than 7 Days: A Preliminary Retrospective Study.

INTRODUCTION: The Japanese packaging instructions for methadone prohibit dose escalation within 7 days of administration initiation as this may result in overdose and subsequent adverse events. However, for terminal cancer patients, evaluation of the effects of methadone may be desirable within 7 days because they have limited prognoses. We aimed to determine the possibility of estimating the adequateness of methadone earlier than the 7th day by investigating the onset timing of analgesic effects and adverse events of methadone in Japanese terminal cancer patients. METHODS: Japanese terminal cancer patients who started taking methadone in Ashiya Municipal Hospital were enrolled from January 1, 2013 to February 28, 2019. Verbal rating scale (VRS) scores on pain and adverse events before and after methadone administration (on days 3, 5, and 7) were retrospectively investigated from medical records. RESULTS: We enrolled 25 patients, of which 20 (80.0%) received methadone until day 7. The VRS score (mean ± standard deviation) on pain was significantly reduced to 0.90 ± 0.55 on day 3, compared with 1.65 ± 0.67 before the administration of methadone (p < 0.05). The mean VRS scores did not differ significantly on days 3, 5, and 7. Additionally, of the 23 patients who received methadone until day 3, 20 (87.0%) showed an analgesic effect on day 3 and 17 (85.0%) received methadone without experiencing serious adverse events until day 7. CONCLUSIONS: The adequateness of methadone in Japanese terminal cancer patients could be determined before day 7, considering the high analgesia incidence and few adverse events 3 days after the methadone administration under careful observation by a physician experienced in methadone administration. However, as this is a preliminary study, the relationship between pharmacokinetic parameters and analgesic effects was not evaluated. Further studies involving pharmacokinetics and multicenter prospective studies are required to support these findings.

[Clinical features of paclitaxel-induced peripheral neuropathy and role of Gosya-jinki-gan].

Paclitaxel (PTX) is frequently used for a chemotherapy of breast cancer and gynecologic cancer. Besides a bone-marrow depression and hypersensitive reaction, the peripheral neuropathy is one of the serious adverse events of PTX. The mechanism of peripheral neuropathy has not been clarified, and few agents have been reported to be effective for the treatment and the prevention of that. Recently, it has been reported that Gosya-jinki-gan is useful for the PTX induced peripheral neuropathy, so we carried a retrospective study(n=82)to evaluate the effectiveness of Gosya-jinkigan with the medical records. It is suggested that peripheral neuropathy developed more rapidly in sequential administration of PTX every week than in administration in 4 weeks cycles consisting of 3 weeks on and 1 week off(5.4w vs. 9.4w). We have also found that Gosya-jinki-gan was possibly effective for the treatment and the prevention of peripheral neuropathy. Additionally Gosya-jinki-gan might be more effective for peripheral neuropathy when it is administered from the beginning of chemotherapy including PTX.

Hand Foot Syndrome Has the Strongest Impact on QOL in Skin Toxicities of Chemotherapy.

Background: Chemotherapy often results in dermatologic toxicities, which decrease quality of life (QOL) of cancer patients. These adverse skin reactions sometimes happen simultaneously. Though previous reports have demonstrated that skin reactions influence QOL, those reports were focused on only one kind of skin toxicity or on the most serious skin toxicity. The aim of this study is to demonstrate the contribution of each skin toxicity to QOL. Methods: This is a cross-sectional study at Kinki Central Hospital. Patients were enrolled who underwent skin toxic chemotherapy from April 1 to June 30, 2017. DLQI and Skindex29 were used to grade the QOL of patients. Also, the severity of skin toxicities was evaluated based on National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 (NCI-CTCAE ver4.0). We investigated how QOL changed with patient demographic and clinical characteristics, the worst skin toxicity grade, and each skin toxicity using statistical analyses. Results: No significant differences were detected between QOL scores (total score of DLQI, emotions domain, symptoms domain, functioning domain and total score of Skindex29) and patient demographic and clinical characteristics (P values were 0.155, 0.086, 0.052, 0.312 and 0.114, respectively). There were statistically significant QOL differences among the grades of the worst skin toxicity (P values were <0.001). Xerosis, paronycia, pigmentation, and hand foot syndrome showed statistically significant associations with some QOL domains analyzed by multiple logistic regression analyses adjusted by demographic characteristics. When adjusted by both demographic characteristics and other skin toxicities, three of xerosis, paronycia, and pigmentation showed no statistically significant associations, but hand foot syndrome showed statistically significant associations in all subdomains and total score of Skindex29 (P values were <0.05). Conclusions: Hand foot syndrome was a stronger factor in decreasing QOL than xerosis, paronychia, pigmentation, or rash. Therefore, especially in hand foot syndrome, prevention, early detection, and daily medical care are necessary to maintain QOL.

Risk Factors for Polypharmacy in Elderly Patients With Cancer Pain.

OBJECTIVE: Polypharmacy (PP) is a burden in elderly patients with cancer pain; however, risk factors for PP remain unclear. The purpose of this study was to investigate the risk factors for PP in this patient population. METHODS: We retrospectively reviewed the medical charts of patients aged ≥65 years with cancer pain who were treated at Osaka University Hospital between February 2014 and June 2016 according to the World Health Organization 3-step ladder for cancer pain relief. We defined PP as ≥5 medications and conducted exploratory research to examine the association between PP and patient characteristics. Performance status (PS) was estimated according to the Eastern Cooperative Oncology Group system and is categorized as good PS (0-1) and poor PS (2-4). RESULTS: We reviewed 206 patients (122 men and 84 women) with a median age of 71 years (range, 65-89 years) and found that 174 patients (84.5%) had PP. In multivariate logistic analysis, PP was significantly associated with an increased number of comorbidities (odds ratio [OR]: 4.93, 95% confidence interval [CI], 2.57-11.42, P < .001), poor PS (OR: 4.50, 95% CI, 1.06-31.68, P = .039), and administration of an anticancer or molecular targeted drug (OR: 2.78, 95% CI, 1.13-7.16, P = .025). CONCLUSIONS: An increased number of comorbidities, poor PS, and administration of an anticancer or molecular targeted drug were considered risk factors for PP in elderly patients with cancer pain. Sharing these risk factors with medical staff will help reduce the occurrence of problems associated with PP.

Validation of a Short-Term, Objective, Prognostic Predictive Method for Terminal Cancer Patients in a Palliative Care Unit Using a Combination of Six Laboratory Test Items.

Background: There is no established method to objectively predict short-term prognosis. Recently, we proposed objective, short-term, prognostic predictive methods that are combinations of laboratory test items: WPCBAL score, derived from six values (white blood cell, platelet, C-reactive protein, blood urea nitrogen, aspartate aminotransferase, and lactate dehydrogenase). However, that study was conducted in an acute-phase hospital to identify the test items useful for prognostic prediction; thus, whether WPCBAL score could be applied to terminal cancer patients in a palliative care unit was unverified. Objective: To verify the usefulness of WPCBAL score for terminal cancer patients. Design: A retrospective study. Setting/Subjects: Patients admitted to the palliative care unit of Ashiya Municipal Hospital (N = 128) in Japan in 2016. Measurements: The sensitivity, specificity, positive predictive value, negative predictive value, accuracy, and area under the receiver operating characteristic curve (AUROC) were compared between WPCBAL score and the Glasgow prognostic score (GPS). Results: For predicting three-week prognosis, WPCBAL score showed higher AUROC compared with GPS (0.7540 and 0.6573, respectively). WPCBAL score predicting two-week prognosis showed greater AUROC than GPS predicting three-week prognosis (0.7491 and 0.6573, respectively). Conclusion: WPCBAL score was verified to objectively predict the two- or three-week prognosis for terminal cancer patients in a palliative care unit. WPCBAL score may be a new option for prognostic prediction for terminal cancer patients.

A Novel Palliative Care Approach Using Virtual Reality for Improving Various Symptoms of Terminal Cancer Patients: A Preliminary Prospective, Multicenter Study.

Background: Some terminal cancer patients wish to "go to a memorable place" or "return home." However, owing to various symptom burdens and physical dysfunction, these wishes are difficult for them to realize. Objective: The aim of the study is to verify whether simulated travel using virtual reality (VR travel) is efficacious in improving symptoms in terminal cancer patients. Design: This is a prospective, multicenter, single-arm study. Setting/Subjects: Twenty participants with terminal cancer were recruited from two palliative care wards; data were collected from November 2017 to April 2018. Measurements: The VR software Google Earth VR® was used. The primary endpoint was the change in the Edmonton Symptom Assessment System scores for each symptom before and after VR travel. Results: The average age of the participants was 72.3 (standard deviation [SD] = 11.9) years. Significant improvements were observed for pain (2.35, SD = 2.25 vs. 1.15, SD = 2.03, p = 0.005), tiredness (2.90, SD = 2.71 vs. 1.35, SD = 1.90, p = 0.004), drowsiness (2.70, SD = 2.87 vs. 1.35, SD = 2.30, p = 0.012), shortness of breath (1.74, SD = 2.73 vs. 0.35, SD = 0.99, p = 0.022), depression (2.45, SD = 2.63 vs. 0.40, SD = 0.82, p = 0.001), anxiety (2.60, SD = 2.64 vs. 0.80, SD = 1.51, p < 0.001), and well-being (4.50, SD = 2.78 vs. 2.20, SD = 1.99, p < 0.001; pre- vs. post-VR travel score, respectively). No participants complained of serious side effects. Conclusions: This preliminary study suggests that VR travel can be efficacious and safe for terminal cancer patients for improving symptom burden.

A New Approach for Determining Short-Term, Objective Prognostic Predictive Methods for Terminal Cancer Patients Based on the Change Point of Laboratory Test Values.

BACKGROUND: In terminal phase cancer, predicting a prognosis precisely plays an important role for patients and their families to live meaningful lives. However, there are no established short-term, objective prognostic predictive methods. OBJECTIVE: To develop simple, short-term, objective prognostic predictive methods through detecting a change point for laboratory test values. DESIGN: A retrospective chart review. SETTING/SUBJECTS: Subjects were cancer patients aged ≥16 years and discharged dead from Osaka University Hospital in 2008. MEASUREMENTS: Using different laboratory test values, new prognostic predictive methods were determined based on either six laboratory test values (white blood cell [WBC], platelet [PLT], C-reactive protein, blood urea nitrogen [BUN], aspartate aminotransferase [AST], and lactase dehydrogenase [LDH]): the WPCBAL score, or five test values (WBC, PLT, BUN, AST, and LDH): the WPBAL score. Their utility, including sensitivity and specificity, was compared with that of Glasgow prognostic scores (GPSs). RESULTS: In total, 121 cancer patients were enrolled. WPCBAL and WPBAL scores showed higher sensitivity (0.88 and 0.91 vs. 0.68), specificity (0.79 and 0.70 vs. 0.53), negative predictive value (0.98 and 0.97 vs. 0.76), and a much larger relative risk (16.5 and 14.2 vs. 1.78) as prognostic predictors within two weeks of death than GPS as a prognostic predictor within three weeks of death. CONCLUSION: This is the first study that suggests that the objective prognostic predictive methods, through detecting the change point of laboratory test values, are useful for predicting short-term prognosis. The WPCBAL score and WPBAL score could objectively predict the remaining lifetime within two weeks of mortality.

[The Present Implementation Status and Problems of Vital-signs Measurement by Community Pharmacists in Home Medical Care in Osaka].

　While the community-based integrated care systems are in the process of being structured currently, more and more community pharmacists want to learn physical assessment skills. However, no large-scale survey focusing on present implementation status and problems of physical assessment by community pharmacists has been conducted yet. Osaka has the 2nd highest number of community pharmacies in Japan now, and the population aged ≥65 years will be expected to become the 3rd highest in 2025. Thus, Osaka can become a national leading model case for community pharmacists' activity in future home medical care. Therefore, this study aimed to reveal the present implementation status and problems of physical assessment by community pharmacists in Osaka, especially focusing on vital-signs. The questionnaires were sent to all the 3571 insurance pharmacies belonging to the Osaka Pharmaceutical Association and 871 pharmacies responded. Many pharmacists recognized the necessity for vital-signs measurement by pharmacists in home medical care (81.5% of pharmacies that offered home medical care and 75.4% of pharmacies that did not offer one). However, the proportion of pharmacies that conduct vital-signs measurement in home medical care was 18.7%, therefore, it was suggested that the present problem is "many pharmacists cannot conduct vital-signs measurement, although they think it should be conducted". Moreover, the most common reason for not measuring vital-signs was the lack of instruments, such as stethoscopes and sphygmomanometer (43.2%). This is the latest report with a large-scale sample, thus, it can serve as valuable knowledge in considering what pharmacists do for the future.

A retrospective chart review of the antiemetic effectiveness of risperidone in refractory opioid-induced nausea and vomiting in advanced cancer patients.

Nausea and vomiting are distressing symptoms in advanced cancer patients. The causes of nausea and vomiting are multifactorial. Among the causes is opioid therapy, the mainstay of cancer pain management. When nausea or other opioid side effects occur, it may hamper pain management and undermine the quality of life of cancer patients. Risperidone exerts an antiemetic effect in animals, but there has been no clinical report on its antiemetic activity. We conducted a retrospective chart review to examine whether risperidone is useful for opioid-induced nausea and vomiting in advanced cancer patients (n=20). Risperidone was given as doses of 1mg once a day. Complete response was observed in 50% of patients (10/20) for nausea and 64% (7/11) for vomiting. Sedation (n=2) was documented as an adverse effect. This observation suggests that risperidone can be an effective antiemetic drug in the treatment of refractory opioid-induced nausea and vomiting in advanced cancer patients.

[Comparison of antiemetic efficacy of 5-HT3 receptor antagonists in orthopedics cancer patients receiving high-dose chemotherapy].

There are no reports comparing the efficacy of 3 selective 5-HT(3) receptor antagonists (Granisetron, Ondansetron, and Ramosetron). We designed a prospective study to compare the efficacy of Granisetron, Ondansetron, and Ramosetron. Thirteen patients gave informed consent to participate in the study. We assigned them to groups taking Granisetron, Ondansetron, or Ramosetron before the high-dose chemotherapy. They themselves reported the extent of their nausea and how many times they vomited per day from the first to the sixth day of chemotherapy. We evaluated their report with PLS (Partial Least Squares) and Welch's t-test. From the results of PLS, it was suggested that CDDP contributed the most and Ramosetron the least to the extent of nausea, while Doxorubicin (ADM)/CDDP contributed the most and Ramosetron the least to the frequency of vomiting. Then we compared the antiemetic effect of the agents regarding the types of chemotherapy. It was concluded that Ramosetron might have been the most effective of the three agents in reducing nausea and vomiting, but with no significant difference.

Desirable Information of Opioids for Families of Patients With Terminal Cancer.

OBJECTIVE: The aims of this study are to clarify the state of information regarding opioids for families and what kinds of experiences they had with opioids while the patient was followed as an outpatient and inpatient. PARTICIPANTS: This study was part of a cross-sectional nationwide survey of bereaved families of patients with cancer, namely, the Japan Hospice and Palliative Care Evaluation 2 study. The participants in this study comprised 572 bereaved families who had experienced the death of a family member during the period from January 2008 to December 2009 at 1 of 103 certificated palliative care units. MAIN OUTCOME MEASURES: In response to the question of "how much improvement was needed for information regarding opioids," 41% answered "improvement is not necessary at all," 43% answered "improvement is slightly necessary," 14% answered "improvement is necessary," and 2% answered "improvement is extremely necessary." Regarding anxiety about the use of opioid, it was found that 14% of respondents indicated "opioids are very safe," 65% of respondents indicated "opioids are relatively safe," 19% of respondents indicated "opioids are not so safe," and 2% of respondents indicated "opioids are not so safe at all." from the information obtained for opioids. It was found that 90% of families agreed with the item, "I would like to be clearly explained that drugs for medical purposes are safe and that the patient will not develop a drug addiction and their life expectancy will not be reduced." CONCLUSION: From this study, it is important for families of patients with cancer to be explained profound and careful information of opioid.
