Comparing Injection Site Reactions of Aprepitant and Fosaprepitant in Gynecologic Cancer Chemotherapy.

BACKGROUND/AIM: The frequency rate of injection site reactions (ISR) due to fosaprepitant meglumine (Fos APR) has been shown to vary depending on the types of combined anticancer drug. This study aimed to elucidate the impact of Fos APR on ISR in patients receiving paclitaxel and carboplatin, with and without bevacizumab therapy (TC±Bev). PATIENTS AND METHODS: This study focused on patients with gynecologic cancer (n=93) who received TC±Bev administration at Fujita Health University Hospital from March 2016 to February 2020, and monitored up to six cycles. The patients were randomly assigned to the Fos APR group (n=47) and the Aprepitant (APR) group (n=46). Using Visual Infusion Phlebitis (VIP) scores, ISR was evaluated by comparing the VIP scores of all cycles using a linear mixed model. The risk factors that contribute to the occurrence of vascular pain throughout all cycles were also examined. RESULTS: The VIP scores of all cycles showed a near significant intergroup difference (p=0.071). Factors that affected the development of vascular pain included Fos APR and age (p=0.027 and 0.049, respectively). Regarding age, patients aged <65 years had a higher risk. Four patients underwent a switch from the originally assigned neurokinin-1 receptor antagonist; in all of these cases, Fos APR was changed to APR for vascular pain. CONCLUSION: Fos APR may increase the risk for ISR associated with TC±Bev therapy for gynecological cancer.

Factors Affecting the Comprehension of Outpatients Receiving Cancer Chemotherapy.

Pharmaceutical consultation targeting outpatients at the Fujita Health University Hospital (Japan) provides support to patients undergoing anticancer drug treatment. This study aimed to explore factors that affect the comprehension of cancer chemotherapy among outpatients who received cancer treatment at our hospital. A questionnaire survey was conducted, and comprehension was scored on a scale of 1-5 (1, no comprehension; 5, full comprehension). When factors other than age and sex [the influence of which on comprehension has been reported in previous reports] were noted, differences in comprehension between the questionnaire items were comparatively analyzed according to the presence/absence of the relevant factors. Overall, 536 patients were included. Age (<70 years) and pharmacist interventions were identified as factors contributing to a comprehension score. The levels of comprehension regarding the name of the cancer chemotherapy, content/schedule of the treatment, purposes of the prescribed drugs, and objectives of blood tests were significantly higher in the group that received the pharmaceutical interventions; conversely, the level of comprehension for the self-management of adverse events was significantly lower in this group than in the group that did not receive any pharmaceutical interventions. Age and interventions by the pharmacist affected the comprehension of cancer chemotherapy by patients.

Correlation between serum albumin and serum zinc in malignant lymphoma.

Objectives: Zinc (Zn) is a cofactor for more than 200 enzymes within the human body. Zn deficiency can result in cell-mediated immune dysfunction. Furthermore, serum Zn levels have been reported to be associated with nutritional status, but this association has not been clarified in malignant lymphoma. This study aimed to examine the deficiency of serum Zn levels and clarify the factors that are correlated with serum Zn in malignant lymphoma. Methods: Initial malignant lymphoma was diagnosed in patients at Fujita Health University Hospital between April 2011 and March 2019. Based on the serum Zn levels, the study population was divided into "deficient" and "low or normal". For the serum Zn levels of patients undergoing pre-chemotherapy, laboratory parameters and nutritional factors were included. We compared these factors between the abovementioned two groups, and the serum Zn levels with its correlation factors were investigated. Results: A total of 77 patients (Deficient group, n=20 and Low or Normal group, n=57) were enrolled. Histology, hemoglobin, serum albumin levels, Glasgow Prognostic Score (GPS), neutrophile-lymphocyte ratio (NLR), prognostic nutrition index (PNI) and Controlling Nutritional Status (CONUT) were significantly different between the two groups. Of these parameters, only serum albumin level was significantly associated with serum Zn level (p=0.0024; estimated regression coefficient, 9.51; adjusted coefficient of determination, 0.28). Conclusions: Poor nutritional status at the initial diagnosis may have affected Zn deficiency in initial malignant lymphoma.

The Influence of Intervening on the Pharmaceutical Consultation Targeting Outpatients with Advanced Non-small Cell Lung Cancer Receiving Erlotinib Treatment.

Erlotinib is used to treat advanced non-small-cell lung cancer (NSCLC), the common serious adverse events are skin disorders. The dose intensity of erlotinib should be maintained as much as possible by an appropriate control of adverse events in order to maintain its efficacy. Therefore, the management of these adverse events related to skin disorders would enable a continuous erlotinib treatment without interruption and dose reduction. This study assessed the effect of pharmaceutical consultation in outpatients who received erlotinib. Participants included patients with NSCLC who received erlotinib therapy for more than 6 months between December 2007 and March 2019. The participants were divided into two groups: the intervention group that included patients who received pharmaceutical consultation targeting outpatients by a pharmacist and the nonintervention group that included patients who did not. We retrospectively investigated patient characteristics, treatment regimens, and treatment efficacy. We included a total of 33 patients (18 and 15 patients in the nonintervention and intervention groups, respectively) in this study. The intervention group had a significantly higher median relative dose intensity (RDI) of erlotinib than the nonintervention group (p = 0.0437). In addition, the pharmaceutical consultation targeting outpatients was identified as a factor contributing to the maintenance of RDI ≥90% (p = 0.0269). The present study indicated that there was improvement in RDI with pharmaceutical consultation targeting outpatients with advanced NSCLC.

Comparison between 5-day aprepitant and single-dose fosaprepitant meglumine for preventing nausea and vomiting induced by cisplatin-based chemotherapy.

PURPOSE: We aimed to compare the preventive effect of 5-day administration of aprepitant with single administration of fosaprepitant meglumine against nausea and vomiting symptoms due to highly emetogenic chemotherapy regimens comprising cisplatin (CDDP). METHODS: Subjects were inpatients who underwent chemotherapy for gastric cancer, esophageal cancer, lung cancer, or head and neck cancer with a regimen comprising 60 mg/m(2) or higher dose of CDDP. In this randomised, open-label, controlled study, the subjects were assigned to a group given aprepitant for 5 days or a group given a single administration of fosaprepitant meglumine. The nausea and vomiting symptoms that emerged within 7 days after the first CDDP administration were investigated with a questionnaire form; the results were compared between the two groups. Risk factors affecting nausea and vomiting symptoms were also investigated. RESULTS: Of the 101 patients enrolled, 93 patients were included (48 in the 5-day aprepitant group and 45 in the single fosaprepitant meglumine group). No significant intergroup differences in the complete response rate or the complete control rate were found over the entire period. The nausea score tended to increase from day 3 in both groups, but no significant intergroup difference was observed. Furthermore, the investigation of risk factors affecting moderate or severe nausea symptoms indicated that the fosaprepitant meglumine administration was not a risk factor. CONCLUSIONS: Single administration of fosaprepitant meglumine was not inferior to 5-day administration of aprepitant for preventing acute and delayed nausea and vomiting symptoms occurring after administration of CDDP (60 mg/m(2) or higher).
