This study investigated the potential of the metaverse in providing psychological support for pediatric and AYA cancer patients, with a focus on those with rare cancers. The research involved ten cancer patients and survivors from four distinct regions in Japan, who participated in metaverse sessions using customizable avatars, facilitating interactions across geographical and temporal barriers. Surveys and qualitative feedback were collected to assess the psychosocial impact of the intervention. The results demonstrated that the metaverse enabled patients to connect with peers, share experiences, and receive emotional support. The anonymity provided by avatars helped reduce appearance-related anxiety and stigma associated with cancer treatment. A case study of a 19-year-old male with spinal Ewing’s sarcoma highlighted the profound emotional relief fostered by metaverse interactions. The findings suggest that integrating virtual spaces into healthcare models can effectively address the unique needs of pediatric and AYA cancer patients, offering a transformative approach to delivering psychosocial support and fostering a global patient community. This innovative intervention has the potential to revolutionize patient care in the digital age.

Background: Advanced cancer therapeutics have improved patient survival, leading to an increase in the number of patients who require long-term outpatient chemotherapy. However, the available schedule options for chemotherapy are generally limited to traditional business hours. Method: In 2017, we surveyed 721 patients with cancer in Okayama, Japan, regarding their preferences for evening and weekend (Friday evening, Saturday, and Sunday) chemotherapy appointments. Results: A preference for evening and weekend appointment options was indicated by 37% of the respondents. Patients who requested weekend chemotherapy were younger, female, with no spouse or partner, living alone, employed, and currently receiving treatment. Among these factors, age and employment status were significantly associated with a preference for weekend chemotherapy, according to multivariate analysis. Conclusion: Our findings reveal a demand for evening and weekend outpatient chemotherapy, especially among young, employed patients.

Purpose: This study aimed to explore the prevalence and cost of wig purchases among patients with cancer in Okayama Prefecture, Japan, and examine the relationship between wig purchases and various demographic, social, and clinical factors. The findings aim to provide insights into appearance care and support systems for patients with cancer, particularly wig subsidies. Methods: A survey was conducted between July and August 2023 among 3000 patients with cancer at 13 designated cancer care hospitals in Okayama Prefecture. Data on demographics, cancer treatment status, and wig purchase details were collected. Statistical analyses, including the Mann–Whitney U test, chi-square test, and logistic regression, were performed to identify factors significantly associated with wig purchases. Results: Among the 863 respondents, 31.4% (271 patients) reported purchasing wigs. Factors significantly associated with wig purchase included young age (odds ratio [OR] = 1.04), female sex (OR = 1.61), and current cancer treatment (OR = 1.16). No significant correlation was found between wig purchase and household income, although higher-income patients tended to purchase more expensive wigs. Conclusion: The findings suggest that younger female patients with cancer and those undergoing treatment were more likely to purchase wigs, highlighting the importance of appearance care and the need for enhanced financial support for low-income patients.

Objective: Corticosteroids are commonly used for symptom relief in patients with terminal cancer, but their use may have an impact on patient survival. We compared the survival of patients with terminal cancer who did and did not receive corticosteroid treatment for symptom relief, stratified by their predicted prognosis. Methods: We retrospectively reviewed consecutive patients with cancer who received corticosteroid treatment for symptom relief in a single palliative care unit. We stratified the patients according to their predicted prognosis using the palliative prognostic (PaP) score either before starting the corticosteroid treatment or at admission for control patients who did not receive a corticosteroid treatment. The 2 groups were compared for survival based on the PaP Scores. Results: We analyzed 204 patients treated with a corticosteroid during the study period and 139 control patients who did not receive corticosteroids during their treatment. No difference was observed in the survival between the treatment and control groups. Conclusion: Corticosteroid treatment for symptom relief in patients with terminal cancer did not affect survival time.

Background and Aim: The effect of corticosteroids on dyspnea in patients with advanced cancer is expected to be associated with patient prognosis, though details about this are unclear. Thus, we aimed to investigate the relationship between prognostic indicators, actual survival, and the effect of corticosteroid administration on dyspnea in patients with advanced cancer.Method: We predicted the prognosis using the PaP score (palliative prognostic score) at the time of corticosteroid administration in 56 consecutive patients with cancer who started corticosteroid treatment for dyspnea at a single palliative care unit, and compared it with the actual survival. In addition, we investigated the relationship between the effect of corticosteroids on dyspnea, the prognostic score before administration, the actual survival, and other background factors.Results: The effect of corticosteroids strongly correlated with the actual survival, but not the prognostic score before corticosteroid administration, although it was correlated with prognostic score and actual survival. In addition, the effect of corticosteroids on dyspnea was less associated with other factors.Conclusion: The corticosteroid effect strongly associated with actual survival, but not the prognostic score. It was suggested that the effect of corticosteroids in patients could be predicted by using a more accurate prognosis prediction in the future.
