Melphalan Febrile Neutropenia Risk Factors.

This study aimed to identify the risk factors of febrile neutropenia(FN)onset associated with melphalan(L-PAM)therapy. Thirty-nine patients(21 men, 18 women)were administered L-PAM intravenously for multiple myeloma(MM)from April 2011 to February 2022 at the Department of Hematology of Gifu Municipal Hospital. Patients were classified into those with and without FN(Grade 3 or higher), complete blood count and liver function tests were performed immediately before starting therapy. Univariate analysis with Fisher's exact probability test was performed. Factors with p<0.2 were considered as independent variables for multivariate analysis in the multiple logistic regression analysis. A multivariate analysis with 2 independent variables, lactate dehydrogenase(LD)level>222 U/L(upper limit of the facility reference value)and white <3.3×103/µL(lower limit of the facility reference value)from the univariate analysis, and FN onset(Grade 3 or higher)as the dependent variable showed that LD level>222 U/L(odds ratio: 6.33, 95% confidence interval: 1.12-35.8, p=0.037)was a significant factor. In conclusion, patients with LD levels >222 U/L immediately before starting therapy require adequate monitoring for FN onset following L-PAM administration.

[Construction and Evaluation of a New Support System for Prescription Inspection of Anticancer Drug Injection Preparation via Quality Control].

Using electronic medical charts at the department of pharmacy of Gifu Municipal Hospital, we constructed a new support system for the prescription inspection of anticancer drug injection preparation via quality control. The system comprises: (1)a "regimen inspection sheet" that can be easily used to check the regimen and clinical laboratory data of patients before the administration of anticancer drugs and(2)an "instruction sheet confirming implementation" that can conveniently confirm the latest clinical laboratory data used to decide the administration of anticancer drugs. Using this system, the safety of anticancer drug administration and work efficiency may be improved.

Impact of pharmacist counseling on reducing instances of adverse events that can affect the quality of life of chemotherapy outpatients with breast Cancer.

BACKGROUND: In recent years, cancer chemotherapy is being conducted at outpatient clinics, wherein pharmacists are involved with patient guidance and management of adverse events as experts in medication therapy. Therefore, we clarified the influence of interventions by pharmacists during counseling of patients with cancer on patients' quality of life. METHODS: To determine this influence, we conducted a survey to assess the quality of life of 39 patients with breast cancer who underwent their initial course of outpatient cancer chemotherapy at Gifu Municipal Hospital. A quality of life survey was conducted before the 1st, 2nd, and 3rd courses of treatment and was based on a method obtained from a survey paper entitled, "Quality of Life Questionnaire for Cancer Patients Treated with Anticancer Drugs." RESULTS: Twenty patients were assigned to the intervention group, which received pharmacist counseling, and nineteen patients were assigned to the non-intervention group, which received no pharmacist counseling. Both groups were compared immediately before the 1st course and 2nd course. Regarding the subscale of social relationships, a significant difference was observed for malaise (p = 0.043), with the non-intervention group experiencing them to a greater degree than the intervention group. Regarding the change between immediately before the 1st course and the 3rd course, a significant difference was observed in the subscale of social relationships for nausea (p = 0.017), with the non-intervention group experiencing it to a greater degree than the intervention group. CONCLUSIONS: The results suggest that receiving pharmacists' guidance on adverse events and individually adjusted prescriptions tailored to address the occurrence of adverse events improved the treatment environment and enhanced the quality of life in the intervention group. These findings are beneficial in maintaining patients' quality of life during cancer treatment. TRIAL REGISTRATION: No. UMIN000027171, Registration date: Apr 27, 2017. Retrospectively registered.

Establishing an Indicator of Hypokalemia in Patients Receiving Anti-Epidermal Growth Factor Receptor Antibodies.

Risk factors for hypokalemia were analyzed in patients who received anti-epidermal growth factor receptor monoclonal antibodies (anti-EGFR MoAbs) at Gifu Municipal Hospital between February 2010 and March 2013. Subjects were 51 patients (27 men and 24 women) with the median age (interquartile range) of 66 (63-72) years. The study period started from the initiation of anti-EGFR MoAbs administration and ended 4 weeks after administration was completed. Patients were categorized into the side effect group if both minimum serum potassium (Min S-K) grade and b grade (pre-treatment S-K grade-Min S-K grade) were B1; otherwise, they were placed into the no side effect group. Univariate analysis for factors to prevent the side effect identified the "concomitant use of hyperkalemia-inducing drugs" to be statistically significant (p=0.010). Multivariate analysis was conducted on factors with a p value of <0.25 in the univariate analysis and on "concomitant use of hyperkalemia-inducing drugs," which was likely to clinically affect S-K decrease, although its p value was >0.25. It showed that "concomitant use of hyperkalemia-inducing drugs" was a significant risk-prevention factor (odds ratio: 0.138, 95% confidence interval[CI]: 0.033-0.581, p=0.007). In conclusion, "concomitant use of hyperkalemia-inducing drugs" is a factor associated with preventing hypokalemia accompanying anti-EGFR MoAbs administration.

[A female chronic myeloid leukemia patient who gave birth after stopping imatinib intentionally but who maintained a major molecular response with interferon].

Imatinib was administrated to a 38-year-old woman with chronic myeloid leukemia(CML). A major molecular response (MMR)(≤5 copies/0.5 µgRNA in Amp-CML detected using the transcription mediated amplification/hybridization protection assay(TMA/HPA)method)was achieved in 18 months. She maintained MMR for 10 months, and wished to become pregnant. Imatinib was stopped intentionally because she wished to plan a pregnancy, but we prescribed interferon alpha (IFN-a)due to the likelihood of the CML recurring after pregnancy. The nausea caused by IFN-a was improved by administrating it during the night, and she gave birth to a healthy baby by a normal delivery, whilst maintaining MMR. In this case, IFN-a treatment gave good clinical results, the patient's prognosis was improved, and she could maintain a good quality of life. We consider this to be an informative example of IFN-a therapy for CML during pregnancy.

The Establishment of Indicators of Thrombocytopenia in Patients Receiving Lenalidomide Therapy.

The onset of thrombocytopenia and related factors was analyzed in patients with multiple myeloma (MM) who were receiving lenalidomide (Len) therapy at the Department of Hematology, Gifu Municipal Hospital between July 2010 and March 2014. We included 28 MM patients (18 males and 10 females) with a median age of 70.5 (range: 55-84) years. The patients were examined from the start of Len therapy until treatment discontinuation, prolongation, or dose reduction. A significant correlation was observed between platelet (Plt) count prior to the start of Len therapy (pre-treatment Plt) and the difference between pre-treatment Plt and the minimum Plt up to the point in time of treatment discontinuation, prolongation, or dosage reduction (min-Plt) (r=0.674, p<0.001). Univariate analysis revealed that factors causing thrombocytopenia of grade 2or above as a side-effect showed a significant difference when the Plt count was below the lower limit of the normal value (<14.0×10(4)/µL)(p=0.011). Factors with p<0.25 in the univariate analysis and daily dosage of Len were examined by multivariate analysis; thus, a Plt count below the lower limit of the normal value was identified as a factor (odds ratio: 15.12, 95% confidence interval [CI]: 1.712-133.5, p=0.015). In conclusion, we suggest that a Plt count below the lower limit of the normal value prior to the start of Len therapy is a prognostic factor for thrombocytopenia as a side-effect of Len therapy.

[Analysis of factors influencing the occurrence of infusion reaction after initial treatment with rituximab].

We investigated factors influencing the occurrence of infusion reactions after initial treatment with rituximab. We included patients who were administered rituximab for the treatment of B-cell non-Hodgkin's lymphoma at the Gifu Municipal Hospital Hematology from February 2010 to March 2013. Fifty-one patients were included; their median age was 72(44-87)years, and 31 were men and 20 were women. We defined the index of infusion reaction as the maximal change in body temperature within 24 hours from the administration of rituximab and evaluated the correlation with change in body temperature and each factor, and differences of change in body temperature between the upper and lower groups divided by standard value of each factor by using the t test without correspondence. The "2,000 U/mL or less group"of soluble interleukin-2 receptor(sIL- 2R)levels and the "over 2,000 U/mL group"showed significant different(p=0.014). The "double value or less group"of a standard value(211 IU/L)and "over double value group"showed significantly different lactate dehydrogenase(LDH)levels (p=0.017). The "lower limit or less group"of the standard value(men: 13 g/dL, women: 12 g/dL)and the "over lower limit group"showed significantly different hemoglobin(Hb)levels(p=0.020). In conclusion, the levels of sIL-2R, LDH, and Hb may predict the occurrence of infusion reaction after the initial administration of rituximab in patients with B-cell non-Hodgkin's lymphoma.
