Prognostic Model of Baseline Medications plus Neutrophil-to-lymphocyte Ratio in Patients with Advanced Non-small-cell Lung Cancer Receiving Immune Checkpoint Inhibitor plus Platinum Doublet: A Multicenter Retrospective Study.

Background: Association between baseline medications plus neutrophil-to-lymphocyte ratio (NLR) and the effectiveness of immune checkpoint inhibitor (ICI) plus platinum doublet remains unknown, despite several reported prognostic models. We used real-world data to investigate whether baseline medications plus NLR predict survival outcomes in patients with advanced non-small-cell lung cancer (NSCLC) receiving ICI plus platinum doublet. Methods: This multicenter, retrospective, observational study conducted in Japan between December 2018 and March 2021 used real-world data of consecutive patients with advanced NSCLC who received ICI (pembrolizumab or atezolizumab) plus platinum doublet as first-line treatment. Progression-free survival (PFS) and overall survival (OS) were estimated using the Kaplan-Meier method. The prognostic score for baseline medications plus NLR was weighted by regression ß coefficients and used to categorize patients into good, intermediate, and poor prognoses groups. In addition, time-dependent receiver operating characteristic curve analyses and univariable and multivariable Cox proportional hazards models were constructed. Results: Overall, 241 patients were included. Poor prognosis was significantly associated with worse PFS (hazard ratio [HR]: 1.78; 95% confidence interval [CI]: 1.08-2.94; P = 0.025) and OS (HR: 3.59; 95% CI: 2.05-6.28; P < 0.001) than good prognosis. Harrell's C-index for this prognostic model was 0.648. Conclusions: Baseline medication plus NLR could predict progressively worse survival outcomes in patients with advanced NSCLC receiving ICI plus platinum doublet and could be used as a prognostic index for poor outcomes.

Comparison between filgrastim biosimilar and filgrastim original for the management of neutropenia after salvage chemotherapy for malignant lymphoma.

In this study, the efficacy and safety of filgrastim biosimilar (F-BS) were retrospectively compared to those of filgrastim original in the treatment of malignant lymphoma with CHASE (± R) or DeVIC(± R) in 78 patients. The median number of filgrastim doses was 11 in the F-BS group and 8 in the filgrastim group after CHASE (± R) (p = 0.8), and 10 in the F-BS group and 10 in the filgrastim group after DeVIC (± R) (p = 0.45). The median days until neutrophil recovery to ≥ 1000/µL was 10 days with F-BS versus 10 days with filgrastim after CHASE ± R (p = 0.59), and 9 days with F-BS versus 10 days with filgrastim after DeVIC ± R (p = 0.828). Febrile neutropenia (FN) was observed in 5 patients (41.7%) in the F-BS group and 9 (52.9%) in the filgrastim group after CHASE ± R therapy (p = 0.616), and in 11 patients (36.7%) in the F-BS group and 9 (47.4%) in the filgrastim group after DeVIC ± R (p = 0.462). The present results suggest that the efficacy and safety of F-BS are comparable to those of filgrastim original, with no significant differences in clinical factors. Use of F-BS also reduced medical costs per course of CHASE ± R therapy by 170.22 US dollars.

Using an online journal club to improve Asian speakers' comfort in using English to discuss and understand research papers written in English.

INTRODUCTION: This study aimed to evaluate the participants' comfort in understanding research papers written in English and discussing such research in English via an Asian online journal club. METHODS: A self-administered online survey was delivered to seven journal club meeting attendees from July 2020 to July 2021. A customer satisfaction analysis was performed to assess the association between the participants' perspectives on program logistics and satisfaction. RESULTS: The recovery rate was 37.0% (44/119). After participating in the journal club, the median scores of critical appraisal skills, knowledge and/or pharmaceutical care skills in clinical practice, and discussion skills in English (assessed using a seven-point Likert scale) improved significantly (compared to pre-participation median scores) from 4 (interquartile range [IQR]: 3-5) to 5 (IQR: 4-6), 5 (IQR: 4-5) to 5 (IQR: 5-6), and 4 (IQR: 2-5) to 5 (IQR: 3-5), respectively (P < 0.0001). The respondents also expressed great appreciation for the benefits and overall qualities of the journal club. Additionally, regarding patient care behavior after participation in the journal club, 34 (77.3%), 17 (38.6%), 16 (36.4%), and 14 (31.8%) respondents reported improvement in "drug information services," "patient assessments," "patient counseling," and "multidisciplinary rounds," respectively. Customer satisfaction analysis revealed that sharing information, mutual discussion, a shift system of presenters and co-chairs, and session duration should be improved as a matter of highest priority. CONCLUSION: The findings suggest that our program could be helpful for Asian pharmacists, pharmacy students, and faculty members of the department of pharmacy.

Patient-related Risk Factors for Nausea and Vomiting With Standard Antiemetics in Patients With Cancer Receiving Carboplatin: A Retrospective Study.

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.

Evaluation of anxiety and salivary chromogranin a secretion in women receiving breast conserving surgery followed by radiation therapy.

We conducted a prospective study to assess the anxiety and salivary Chromogranin A (CgA), which is considered to be a biomarker of the stress response, in outpatients receiving breast conserving surgery followed by radiation therapy (RT) to the whole breast. Fifty consecutive patients who received whole-breast RT were enrolled in this study. The anxiety levels were measured by the State-Trait Anxiety Inventory (STAI) at the beginning of RT (baseline), 30 Gy, completion of RT, and 1 and 3 months after RT. Salivary CgA levels were also measured at the same time. The mean state anxiety score for all patients was 46.16 with a standard error (SE) of 1.57 at the beginning of RT (baseline) which continued to decline during and after RT. It reached its lowest score with 36.34 ± 1.56 at 3 months after RT (p < 0.0001). The mean trait anxiety score for all patients was 43.10 ± 1.54 at baseline and remained constant during RT but began to decline after completion of RT and reached a low level at 3 months after RT (p = 0.0021). The mean salivary CgA concentration for all patients demonstrated no consistent trends over time, but at 30 Gy the concentration showed a significant decreasing pattern (p = 0.0473). Salivary CgA concentrations and state anxiety and trait anxiety scores at all time points showed no correlation. The mean anxiety scores measured by STAI showed no positive correlation with salivary CgA concentration for breast cancer patients undergoing radiation therapy following breast conserving surgery.

[Optimal therapeutic concentration of tacrolimus in adult patients undergoing reduced-intensity cord blood transplantation].

To investigate the effectiveness and safety of GVHD prophylaxis using FK506 alone as a continuous infusion, 104 patients who underwent reduced-intensity cord blood transplantation were retrospectively reviewed. The respective incidence of acute GVHD was 25 grade 1(24. 1%), 19 grade2(18. 3%), 15 grade3(14. 4%), and 4 grade4(3. 8%), which are comparable to that in the literature. The incidences of grade 2 and greater acute GVHD were 32 out of 69(46. 4%)for those whose wholeblood concentration of FK506 werele ss than 13 ng/mL, whereas 6 out of 35(17. 1%)for those FK5 06 were greater than 13 ng/mL. The differenceies between above and below 13 ng/mL were statistically significant(p=0. 008). There were 19 cases(18. 3%)of renal dysfunction, although none required hemodialysis. There were only 4 patients who discontinued FK506, which further confirmed the safety of FK506 alone. Together with our previous report on the upper limit of FK506(17 ng/mL)and these results, we recommend the optimal serum concentration of FK506 to range from 13 to 17 ng/ mL.

[Analysis of blood concentrations following oral administration of beclomethasone dipropionate for gut GVHD].

In this study, we investigated the level of gut absorption following oral beclomethasone dipropionate (BDP) administration by measuring the blood concentration of its metabolites measured by LC-MS/MS using the HPLC method. Five patients who were administered BDP orally for gut GVHD were included. The blood concentrations of beclomethasone-17-monopropionate (17BMP), which is one of the active metabolites of BDP, were 618 approximately 1, 749 pg/mL in 4 of the studied 5 patients, which was comparable to that after inhalation of BDP; however, it was relatively higher in one patient (2,439+/-161 pg/mL). As the blood concentration of 17BMP in this study patient was higher compared with healthy volunteers administered a single oral BDP 4 mg, GVHD patients might have a higher concentration than healthy volunteers. Given that a higher grade of gut GVHD was associated with a higher blood level of 17BMP, BDP absorption might be associated with gut mucosal injury. Thus, the systemic adverse effect following oral BDP administration might not be negligible especially in gut GVHD patients.
