A Randomized Controlled Trial of Betamethasone on Fatigue in Patients With Advanced Cancer.

CONTEXT: Fatigue is one of the most uncomfortable physical symptoms seen in patients with advanced cancer. Previous studies have reported on the efficacy of corticosteroids from Western countries. OBJECTIVES: To assess the effectiveness of 4mg betamethasone improving fatigue among Japanese patients with advanced cancer. METHODS: A randomized, double-blind, placebo-controlled trial enrolled eligible patients with advanced cancer expected to survive 1-2 months, with an Eastern Cooperative Oncology Group Performance Status of 2-3, and experiencing fatigue according to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-15-palliative criteria. Participants received twice-daily oral administration of 2 mg betamethasone (4 mg/d) or placebo for seven days, with fatigue assessed using EORTC QLQ-C15-PAL subscale and numerical rating scale (NRS) score (at baseline and day seven). The trial was registered under the University Hospital Medical Information Network (UMIN)000011913. RESULTS: Among the 267 screened patients, 81 were eligible, of which 70 were evaluable (betamethasone, 33; placebo, 37). The mean difference in the EORTC-QLQ-C15-PAL fatigue subscale was -8.2 (95% CIs: -22.3, 0.0; P = 0.178) and in a NRS for fatigue was -1.2 (95% CIs: -2.5, -0.01; P = 0.048), respectively. Emotional function, appetite loss, and global-health were slightly better in the betamethasone group than in the placebo group. CONCLUSION: The impact of betamethasone 4 mg/d on alleviating fatigue in patients with advanced cancer in the last weeks of life did not reach statistical significance in the EORTC-QLQ-C15-PAL as the primary endpoint, however, it was significant in the NRS, the secondary endpoint.

Dexamethasone-sparing on days 2-4 with combined palonosetron, neurokinin-1 receptor antagonist, and olanzapine in cisplatin: a randomized phase III trial (SPARED Trial).

BACKGROUND: This study evaluated the non-inferiority of dexamethasone (DEX) on day 1, with sparing on days 2-4 in cisplatin-based chemotherapy. METHODS: Patients with malignant solid tumors who were treated with cisplatin (≥50 mg/m²) were randomly assigned (1:1) to receive either DEX on days 1-4 (Arm D4) or DEX on day 1 (Arm D1) plus palonosetron, NK-1 RA, and olanzapine (5 mg). The primary endpoint was complete response (CR) during the delayed (24-120 h) phase. The non-inferiority margin was set at -15%. RESULTS: A total of 281 patients were enrolled, 278 of whom were randomly assigned to Arm D4 (n = 139) or Arm D1 (n = 139). In 274 patients were included in the efficacy analysis, the rates of delayed CR in Arms D4 and D1 were 79.7% and 75.0%, respectively (risk difference -4.1%; 95% CI -14.1%-6.0%, P = 0.023). However, patients in Arm D1 had significantly lower total control rates during the delayed and overall phases, and more frequent nausea and appetite loss. There were no significant between-arm differences in the quality of life. CONCLUSION: DEX-sparing is an alternative option for patients receiving cisplatin; however, this revised administration schedule should be applied on an individual basis after a comprehensive evaluation.

Encouraging outpatients in an acute hospital for the relief of cancer-related pain: a qualitative study.

PURPOSE: To identify the processes of cancer-related pain relief and exacerbation faced by outpatients in an acute care hospital and to examine the support needed for outpatient pain control. METHODS: We conducted semi-structured, in-depth interviews with patients from the outpatient department of Showa University Northern Yokohama Hospital in Kanagawa Prefecture, Japan. Participants were recruited by purposive sampling. From the recorded data, verbatim transcripts were made and used as textual data for analysis by consistent comparative method. RESULTS: Between April 2018 and April 2022, interviews were conducted with 30 participants. Analysis of the verbatim transcripts generated 13 categories from 27 concepts. Category relationships were examined, and a conceptual framework was developed. Outpatients went from being in a state of hesitation towards consultation with medical professionals to receiving individual consistent follow-ups by medical professionals in the hospital and community pharmacies, which led to patient teleconsultations when their physical condition changed, leading to an improvement of pain. CONCLUSION: The process of relief and exacerbation of cancer-related pain experienced by outpatients in the acute care hospital reveals that the provision of consistent follow-up through remote or in-person interviews has an important role to play in pain management, as it helps to build relationships between patients and medical professionals. Alternatively, when outpatients exhibited endurance, their pain worsened, and they fell into a negative cycle of poor pain control.

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.

Five cases of skin desquamation due to bevacizumab combined with docetaxel-carboplatin in ovarian cancer.

The standard of care for ovarian cancer chemotherapy is paclitaxel-carboplatin. In Stage III and Stage IV patients, the addition of bevacizumab has been reported to be effective, and bevacizumab combined with paclitaxel-carboplatin and bevacizumab combined with docetaxel-carboplatin are used. Patients who received bevacizumab combined with docetaxel-carboplatin experienced a high incidence of skin hardening followed by peeling. In patients treated with bevacizumab combined with docetaxel-carboplatin, we experienced a high incidence of post-sclerotic peeling of the skin, a symptom that is rarely seen with paclitaxel-carboplatin (TC), docetaxel-carboplatin (DC), or bevacizumab combined with paclitaxel-carboplatin, and has been reported in a few cases. Therefore, we investigated the actual situation of skin desquamation caused by bevacizumab combined with docetaxel-carboplatin. Thirty-one patients were included in the study, and their age (mean ± SD) was 62.9 ± 9.0. The breakdown of treatment was as follows: TC in nine patients, bevacizumab combined with paclitaxel-carboplatin in ten patients, DC in six patients, and bevacizumab combined with docetaxel-carboplatin in six patients. No number of patients with TC or bevacizumab combined with paclitaxel-carboplatin showed skin desquamation. One for DC, and five for bevacizumab combined with docetaxel-carboplatin. The five patients treated with bevacizumab combined with docetaxel-carboplatin improved with topical steroids and moisturizers, but symptoms repeatedly appeared after each course. Skin desquamation was more frequent in bevacizumab combined with docetaxel-carboplatin.

Study protocol for SPARED trial: randomised non-inferiority phase III trial comparing dexamethasone on day 1 with dexamethasone on days 1-4, combined with neurokinin-1 receptor antagonist, palonosetron and olanzapine (5 mg) in patients receiving cisplatin-based chemotherapy.

INTRODUCTION: Dexamethasone (DEX) is administered for multiple days to prevent chemotherapy-induced nausea and vomiting for patients receiving highly emetogenic chemotherapy (HEC); however, its notorious side effects have been widely reported. Although our multicentre randomised double-blind comparative study verified non-inferiority of sparing DEX after day 2 of chemotherapy when combined with neurokinin-1 receptor antagonist (NK1-RA) and palonosetron (Palo) for patients receiving HEC regimen, DEX sparing was not non-inferior in patients receiving cisplatin (CDDP)-based HEC regimens in subgroup analysis. Recently, the efficacy of the addition of olanzapine (OLZ) to standard triple antiemetic therapy on HEC has been demonstrated by several phase III trials. This study aims to confirm non-inferiority of DEX sparing when it is combined with NK-1RA, Palo and OLZ in patients receiving CDDP-based HEC regimens. METHODS AND ANALYSIS: This is a randomised, double-blind, phase III trial. Patients who are scheduled to receive CDDP ≥50 mg/m2 as initial chemotherapy are eligible. Patients are randomly assigned to receive either DEX on days 1-4 or DEX on day 1 combined with NK1-RA, Palo and OLZ (5 mg). The primary endpoint is complete response (CR) rate, defined as no emesis and no rescue medications during the delayed phase (24-120 hours post-CDDP administration). The non-inferiority margin is set at -15.0%. We assume that CR rates would be 75% in both arms. Two hundred and sixty-two patients are required for at least 80% power to confirm non-inferiority at a one-sided significance level of 2.5%. After considering the possibility of attrition, we set our final required sample size of 280. ETHICS AND DISSEMINATION: The institutional review board approved the study protocol at each of the participating centres. The trial result will be presented at international conferences and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: UMIN000032269.

[Evaluation of the Tolerability of Gemcitabine and Cisplatin Combination Chemotherapy with a Small Quantity of Replacement Fluid for Biliary Tract Cancer].

Cisplatin therapy induces kidney injury as a side effect. Thus, replacement fluid must be administered to prevent kidney injury. In our hospital, we use a Gemcitabine and Cisplatin combination chemotherapy (GC) at a total volume of approximately 500 mL for biliary tract cancer. We investigated the safety of GC with a small amount of replacement fluid. As a result, no serious adverse events and renal injury occurred that required discontinuation of treatment. The median overall survival time was 260 d (95% confidence interval, 154-367 d). This study suggests that GC with a small amount of replacement fluid could be performed tolerability. But we need to be careful about choosing patients such as patients who can drink 1 L orally and patients who can be treated as outpatients.

Anthracycline could be essential for triple-negative breast cancer: A randomised phase II study by the Kanagawa Breast Oncology Group (KBOG) 1101.

BACKGROUND: It is important to determine whether anthracycline-containing regimens or taxane-containing regimens are more effective in individual patients. The present study compared the efficacy of six cycles of docetaxel and cyclophosphamide (TC6) with that of three cycles of 5-fluorouracil, epirubicin and cyclophosphamide followed by docetaxel (FEC-D) in Japanese patients with hormone receptor (HR)-negative breast cancer (BC) to identify subtypes requiring anthracycline treatment. METHODS: The study included 103 patients with operable HR-negative BC. Of these patients 53 received FEC-D and 50 received TC6. The primary endpoint was pathological complete response (pCR). The secondary endpoints were safety, breast-conserving surgery, disease-free survival (DFS) and overall survival (OS). The predictive factors for each regimen were evaluated. RESULTS: Of the 103 patients, 97 completed the study (FEC-D, 50 patients; TC6, 47 patients). The pCR rate was higher with FEC-D (36%) than with TC6 (25.5%); however, the difference was not significant (P = 0.265). TC6 was safer than FEC-D, as the adverse events with docetaxel in the FEC-D regimen were similar to those with the TC6 regimen. Among patients with basal BC, the pCR rate was significantly higher with FEC-D (42.9%) than with TC6 (13.6%; P = 0.033). Among patients with triple-negative breast cancer (TNBC), the DFS and OS were significantly better with FEC-D than with TC6 (P = 0.016 and P = 0.034, respectively). CONCLUSION: TC6 was not as effective as FEC-D for treating HR-negative BC, as TC6 was not sufficient to treat TNBC, particularly the basal subtype. Our findings suggest that anthracyclines are better treatment options than taxanes for basal BC.

A cross-sectional survey of methods for controling hand-foot syndrome in patients receiving capecitabine treatment.

Medical personnel actively provide patients taking capecitabine with information on the items to prevent and treat hand-foot syndrome (HFS). However, they are typically unable to ascertain the extent of patient compliance with the recommended items. Thus, the aim of the present study was to ascertain the association between patient compliance with preventative measures for HFS and the development of HFS. Subjects included 90 patients who were treated with a drug regimen that included capecitabine. Patients were treated at one of four facilities between July 2015 and January 2017. The main parameters studied were the extent to which items to prevent and treat HFS were (or were not) followed, and the associaiton between this extent and the development of HFS symptoms. A manual prepared by a pharmaceutical company that manufactures capecitabine describes 15 routine items to follow in order to prevent and treat HFS. The two activities patients most often performed were 'applying a moisturizer' (74.1%) and 'keeping one's skin clean (e.g., washing one's hands and feet)' (64.7%). The two activities patients least often performed were 'using sunscreen on exposed areas' (14.1%) and 'using soft insoles' (11.8%). Patients who performed more items to prevent and treat HFS were significantly less likely to develop symptoms of HFS (P=0.022). Based on these findings, it is recommended that medical personnel provide instructions to the patients regarding the specific items necessary to prevent and treat HFS, and to follow-up with the patients regarding their compliance, with an emphasis on the items they are less likely to take and on the instructions to avoid external irritants. Following these guidelines should lead to qualitative improvement in HFS management.

The pharmacokinetics of mianserin suppositories for rectal administration in dogs and healthy volunteers: a pilot study.

BACKGROUND: We formulated mianserin suppositories for the treatment of delirium and evaluated their pharmacokinetics by measuring plasma drug concentrations in dogs and healthy human volunteers. METHODS: Mianserin suppositories were prepared by a melting technique using Tetramide® tablets and Witepsol H-15 as the suppository base. Pharmacokinetics of this 30-mg mianserin preparation were evaluated in three beagle dogs and three healthy adult males, in line with ethics committee approval. Plasma mianserin levels were determined using gas chromatography-mass spectrometry. RESULTS: In dogs, the maximum plasma mianserin concentration (Cmax) was 1.3 ± 0.4 ng/mL, the time to Cmax (tmax) was 5.5 ± 4.3 h, and the area under the plasma concentration-time curve from 0 to 24 h (AUC0-24) was 18.9 ± 1.9 h・ng/mL. In humans, the Cmax was 14.6 ± 6.3 ng/mL, the tmax was 8 h, and the AUC0-24 was 266 ± 103 h・ng/mL. CONCLUSIONS: The current study characterized the pharmacokinetics of mianserin suppositories in dogs and humans. As compared to oral administration, the suppositories produced a lower Cmax and a delayed tmax, although AUC0-24 values were comparable. It will be necessary to identify an appropriate dose that produces an adequate plasma mianserin concentration for effective and safe clinical use. TRIAL REGISTRATION: UMIN000013853.
