Objective: Almost half of all patients with cancer experience dyspnea, which can have various causes. Although systemic corticosteroids are administered to relieve symptoms, their efficacy has not been established. This systematic review aims to determine the efficacy of systemic corticosteroids for dyspnea in patients with cancer. Methods: CENTRAL, MEDLINE, EMBASE, and Ichushi-Web databases were searched for articles published from their inception to September 23, 2019, on studies of systemic corticosteroid administration for dyspnea in patients with cancer. The primary outcome measure was dyspnea intensity, as assessed by patient-reported outcomes. Secondary outcome measures were quality of life, delirium, and severe adverse events. Results: Two RCTs were included in the meta-analysis. With regard to alleviating dyspnea, the systematic corticosteroid group was associated with significantly greater dyspnea relief than the placebo group (mean difference: −0.71 [95% CI: −1.4 to −0.03]). However, a meta-analysis of quality of life and delirium could not be performed due to insufficient data. Analysis of severe adverse events showed no significant difference in their incidence between the corticosteroid and control groups (relative rate: 0.96 [95% CI: 0.19-4.93]). Conclusions: Systemic corticosteroids may be effective in treating dyspnea in patients with cancer, particularly those with lung involvement. Limiting the conditions for which corticosteroids are approved is expected to promote their appropriate use and minimize their adverse effects. However, further investigation is needed to determine the appropriate dosage, and the conditions in which corticosteroids are effective.

As the demand for end-of-life care increases, the development of a well-structured training and certification system for palliative medicine specialists is becoming increasingly important. In South Korea, a certification system for palliative care physicians has been in place since 2019, managed by the Korean Society for Hospice and Palliative Care. To further develop this certification system and training process, this review aims to describe hospice and palliative medicine certification programs across eight countries/regions—the United States, the United Kingdom, Australia, Japan, Taiwan, Hong Kong, and South Korea—to identify key differences and draw insights for enhancing Korea's physician training and certification system. Most countries/regions recognize hospice and palliative medicine as medical subspecialty and provide standardized training and certification pathways. Training durations range from 1-year fellowships to multiyear structured programs with clinical experience. Japan’s tiered certification system offers a flexible approach based on care settings and physicians’ expertise. However, Korea’s system lacks in-depth clinical experience and government recognition, limiting its sustainability. To strengthen palliative care in Korea, it is essential to enhance training duration, expand clinical exposure, and foster multispecialty collaboration. A tiered certification system adapted to Korea’s healthcare environment and supported by government policy could improve both the quality and reach of palliative care services. These findings can inform future policy and educational reforms to ensure more effective and sustainable training of palliative care professionals in Korea.

Purpose: The purpose of this study was to clarify the current status of Do-Not-Resuscitate discussions (DNRd) with terminally ill cancer patients in Japan and the psychological burden on bereaved families depending on whether or not a DNRd is performed. Method: A multicenter prospective observational study of advanced cancer patients admitted to 23 palliative care units (PCUs) in Japan was conducted, and a questionnaire survey of bereaved families was also conducted after patients died. Result: 1,605 patients were included in the analysis, and 71.4% of patients had a DNRd with doctors before PCU admission, 10.8% at admission, and 11.4% during admission. In contrast, 93.3% of family members had a DNRd with doctors before PCU admission, 48.4% at admission, and 52.1% during admission. Conclusion: Although DNRd was performed between patients and physicians in 72.3% of cases at any point throughout the course of time from before PCU admission to death, there was no evidence of psychological burden such as depression or complicated grief in the bereaved families due to patient participation in DNRd.

This paper aimed to summarize the current situation of prognostication for patients with an expected survival of weeks or months, and to clarify future research priorities. Prognostic information is essential for patients, their families, and medical professionals to make endof-life decisions. The clinician’s prediction of survival is often used, but this may be inaccurate and optimistic. Many prognostic tools, such as the Palliative Performance Scale, Palliative Prognostic Index, Palliative Prognostic Score, and Prognosis in Palliative Care Study, have been developed and validated to reduce the inaccuracy of the clinician’s prediction of survival. To date, there is no consensus on the most appropriate method of comparing tools that use different formats to predict survival. Therefore, the feasibility of using prognostic scales in clinical practice and the information wanted by the end users can determine the appropriate prognostic tool to use. We propose four major themes for further prognostication research: (1) functional prognosis, (2) outcomes of prognostic communication, (3) artificial intelligence, and (4) education for clinicians.

Objective: To evaluate the efficacy of high-flow nasal cannula oxygen (HFNC) for dyspnea in patients with advanced disease. Methods: A literature search was conducted using MEDLINE, Cochrane Library, EMBASE, and Ichu-shi Web. Inclusion criteria were: 1) randomized controlled trials evaluating the effect of HFNC on dyspnea; 2) aged 18 years or older with advanced disease with hypoxemia; 3) control group was conventional oxygen therapy or noninvasive positive pressure ventilation. Exclusion criteria were: 1) patients in intensive care unit, 2) weaning from ventilator. Results: Six studies (4 from database searches, and 2 from hand searches) were included. In the 2 studies evaluating short-term intervention, one showed HFNC was more efficacious, and the other conventional oxygen was more efficacious. In the 2 studies evaluating long-term interventions: one showed HFNC was more efficacious, and the other showed no significant difference. In the 2 studies evaluating the intervention during exercise, one showed HFNC was more efficacious, and the other showed no significant difference. Conclusion: HFNC may be effective for dyspnea in patients with advanced disease associated with hypoxemia.

Background: Factors requiring midazolam in addition to systemic opioids to control dyspnea in cancer patients have yet to be evaluated. Methods: We retrospectively analyzed data for cancer patients who received systemic opioids to relieve dyspnea from April 2019 to July 2021 in Wakayama Medical University Hospital, Japan. Patients were divided into an opioid-alone group and an opioid plus midazolam group, according to the treatment of dyspnea. Results: The total of 107 patients included 85 patients (79.4%) in the opioid alone group and 22 patients (20.6%) in the opioid plus midazolam group. Age<60 years (p=0.004) and male sex (p=0.034) was significantly associated with the addition of midazolam. Multivariate analysis found age <60 years (OR=5.34, 95%CI: 1.66–17.21; p=0.005) was associated with the addition of midazolam. Conclusion: Age <60 years is factor requiring midazolam in addition to systemic opioids to control dyspnea in cancer patients.

Objective: To evaluate the efficacy of fan therapy for the relief of dyspnea in patients with chronic progressive disease. Methods: A systematic electronic database search of all available articles published before October 23, 2019 was conducted using Ichushi-Web of the Japan Medical Abstract Society databases, CENTRAL, EMBASE, and MEDLINE. In addition, a hand-search for updates was performed using PubMed on June 30, 2020 and December 7, 2021. The inclusion criteria were: 1) any RCTs comparing the effect of fan therapy with any other intervention, and 2) patients aged ≥18 years. Exclusion criteria were: 1) duplicate references, and 2) conference presentations. Results: We identified 110 studies, of which 10 met our criteria for inclusion. Finally, five studies were used in the meta-analysis. Fan therapy significantly improved dyspnea in patients with chronic progressive disease compared to control groups with a standardized mean difference of −1.43 (95% confidence interval: −2.70 to −0.17, I2=94%, p<0.0001). Conclusion: Fan therapy was found to be effective in reducing dyspnea in chronic progressive disease.

Background: Although practicing advanced care planning (ACP) has recently been recommended, little is known about physicians’ practice of ACP, and barriers to ACP in Japan. We aimed to clarify the proportion of physicians practicing ACP and explore barriers to ACP. Methods: We conducted a cross-sectional survey among physicians at a tertiary hospital (934 beds) in 2019, and asked them about their practice and awareness of ACP as well as beliefs regarding end-of-life discussions. A multivariate logistic regression analysis was conducted to explore barriers to their practice of ACP. Results: In total, 90 of 186 physicians responded (response rate, 48%). Forty-two (46%; 95% confidence interval=37-57%) reported that they practiced ACP. In multivariate analysis, determinants of “not” practicing ACP included the lack of awareness of ACP and physicians’ greater beliefs regarding the lack of resources as well as the lack of time and perception of burden. Conclusion: Even at the tertiary hospital, only less than a half of physicians practiced ACP, and the lack of their awareness of ACP and various beliefs served as barriers to their practice. Initiatives to raise awareness of ACP and optimize the management to ensure sufficient time and resources for physicians may be promising to promote ACP.

Objectives: To explore background factors contributing to learning needs among physicians in palliative care specialty training. Methods: We conducted a questionnaire survey of physicians in specialty training in palliative care who were within 15 years after medical school graduation. The unmet learning needs (referred to as “needs”) were evaluated on a 5-point scale. Factor analysis was performed to identify underlying subscales of needs. Univariate analysis was performed using an average score of each subscale as a dependent variable and background factors as independent variables. Results: Of 284 physicians, 253 (89%) responded, and 229 were eligible after we had excluded resident physicians with less than 2 years of clinical experience and board-certified palliative care physicians. Factor analysis identified six subscales of the unmet learning needs: research, time, specialist, network, quality, and comprehensiveness. Background factors with significant between-group differences with the effect size of 0.4 or more included: 1) not working at a certified training facility, 2) not working or training at a big hospital, and 3) the number of palliative care physicians being 2 or less in the facility. Conclusion: Improvement of the training system is urgently needed for young physicians who are working at small or non-certified facilities for specialty training, or who have few palliative care colleagues.

A 77-year-old-woman was hospitalized at our institution following the diagnosis of severe aortic and mitral stenoses. Although she had thrombocytopenia before surgery, bone marrow examination revealed no abnormality. Thrombocytopenia was thought to be caused by shear stress accompanying valvular diseases. She underwent surgery for the replacement of aortic and mitral valves and the resection of left ventricular outflow tract myocardium. Because the mitral valve involved the calcification of the annulus the valve replacement was performed after decalcification using CUSA. After surgery, she experienced a transient sick sinus syndrome ; however, the overall course was good, and the platelet counts spontaneously recovered. More than 12 months have passed since surgery, but the platelet counts remains around 110,000.
