Objective: The Japanese Psycho-Oncology Society and the Japanese Association of Supportive Care in Cancer have recently revised the clinical practice guidelines for delirium in adult cancer patients. This article reports the process of developing the revised guidelines and summarizes the recommendations made., Methods: The guidelines were developed in accordance with the Medical Information Network Distribution Service creation procedures. The guideline development group, consisting of multi-disciplinary members, created three new clinical questions: non-pharmacological intervention and antipsychotics for the prevention of delirium and trazodone for the management of delirium. In addition, systematic reviews of nine existing clinical questions have been updated. Two independent reviewers reviewed the proposed articles. The certainty of evidence and the strength of the recommendations were graded using the grading system developed by the Medical Information Network Distribution Service, following the concept of The Grading of Recommendations Assessment, Development, and Evaluation system. The modified Delphi method was used to validate the recommended statements., Results: This article provides a compendium of the recommendations along with their rationales, as well as a short summary., Conclusions: These revised guidelines will be useful for the prevention, assessment and management of delirium in adult cancer patients in Japan., (© The Author(s) 2023.

Purpose: Although treatment outcomes for childhood cancer have improved in recent years, some patients continue to experience physical symptoms and psychological stress several years after the end of treatment. This study aimed to examine the correlation between the quality-of-life (QOL) scores of childhood cancer survivors (CCSs) aged 18-39 and (1) their families and (2) the time since the end of treatment. Methods: Measuring the QOL of CCSs attending the long-term follow-up (LTFU) and those of their families. The Short-Form Health Survey (SF-36) was used for CCSs and the Caregiver Quality of Life Index-Cancer (CQOLC) for their families. Spearman's rank correlation analyses were used to examine the relationship between the CCSs' and their families' QOL and the time since the end of treatment. Results: Twenty-nine CCSs (mean age, 24.2 years; mean the time since the end of treatment, 13.9 years), each paired with one family member, were included. Time since the end of treatment was positively correlated with the CCSs' QOL on the physical component score ( ρ  = 0.42, p  = 0.03) and negatively correlated with mental health (MH) ( ρ  = -0.50, p  = 0.01), a subscale of the mental component score (MCS). Furthermore, the CCSs' QOL on the MCS was positively correlated with their families' QOL scores ( ρ  = 0.58, p  < 0.01). Conclusion: Psychological stress may persist in CCSs long after treatment, even when physical symptoms improve. Therefore, it is necessary to establish a comprehensive support system for the LTFU of CCSs, including MH care and QOL monitoring for patients and their families.

Delirium is a condition in which the main symptom is a mild disturbance of consciousness caused by a physical abnormality or medication, and various symptoms such as cognitive dysfunction, hallucinations, delusions, and mood swings appear with any disease. Delirium is frequently observed in patients with cancer, especially in the terminal stage, and is observed in about 90% of patients just before death. Hypercalcemia due to bone metastases, brain metastases, and the use of opioids and steroids for symptom relief are direct factors in the development of delirium. Furthermore, there are many opportunities to encounter delirium at the end of life caused by conditions that are difficult to recover from, such as brain metastasis, liver failure, and hypoxic encephalopathy. In the management of delirium, "search for the cause(s)and its treatment"and"environmental adjustment"are the most important. Then, pharmacotherapy is considered to reduce the severity of delirium. Antipsychotics are the basic medication of choice. The route of administration, half-life, dosage form, adverse events of medication, as well as patient factors such as the presence or absence of diabetes and the subtype of delirium should be comprehensively considered when selecting a medication. The timing of medication discontinuation should also be kept in mind once medication therapy is initiated. On the other hand, when delirium is caused by factors that are difficult to recover from, the goal of treatment is to alleviate the painful symptoms caused by delirium, and it is important to take a holistic approach for patients and family members.

Young adult survivors of childhood cancer may have a perception gap with their families. Patients aged 18-39 years after treatment of cancer and their families (28 pairs) completed a survey that contained questions on health-related quality of life using the 36-item short form survey. There was a significant difference in the role-social component score (mean difference -2.23; p  = 0.04) with family reporting higher scores than patients. Families may overestimate the social function of cancer survivors, emphasizing the importance of the long-term follow-up by taking into account the risk of a gap (IRB approval No.: R2257-1).

Background: Clinical usefulness of trazodone for delirium in patients receiving palliative care is unclear. Objectives: To examine the safety and effectiveness of trazodone for delirium. Design: A secondary analysis of a multicenter prospective observational study. Setting/Subjects: The setting involves nine psycho-oncology consultation services and 14 inpatient palliative care units in Japan. Measurements: The measurement involves the Delirium Rating Scale (DRS) Revised-98 for effectiveness and the CTCAE (Common Terminology Criteria for Adverse Events) version 4 for safety assessments. Results: Thirty-eight patients enrolled the study. Mean age was 75 years. After three-day observation, the DRS total score (11.6 ± 5.3 to 8.7 ± 6.5 [difference -2.9, 95% confidence interval -5.3 to -0.5, p  = 0.02]); sleep-wake cycle disturbance ( p  = 0.047), lability of affect ( p  < 0.001), and motor agitation subscales ( p  < 0.001) were significantly decreased. The most frequent adverse event was somnolence ( n  = 9). Conclusions: Low-dose trazodone treatment was generally safe and may be effective in reducing delirium severity.

Background: The Japanese Psycho-Oncology Society and Japanese Association of Supportive Care in Cancer recently launched the clinical practice guidelines for delirium in adult cancer patients. The aim of the guidelines was to provide evidence-based recommendations for the clinical assessment and management of delirium in cancer patients. This article reports the process of developing the guideline and summarizes the recommendations made., Methods: The guidelines were developed in accordance with the Medical Information Network Distribution Service creation procedures. The guideline development group, consisting of multidisciplinary members, formulated nine clinical questions. A systematic literature search was conducted to identify relevant articles published prior to through 31 May 2016. Each article was reviewed by two independent reviewers. The level of evidence and the strength of the recommendations were graded using the grading system developed by the Medical Information Network Distribution Service, following the concept of The Grading of Recommendations Assessment, Development and Evaluation system. The modified Delphi method was used to validate the recommendation statements., Results: This article provides a summary of the recommendations with rationales for each, as well as a short summary., Conclusions: These guidelines will support the clinical assessment and management of delirium in cancer patients. However, additional clinical studies are warranted to further improve the management of delirium., (© The Author(s) 2020. Published by Oxford University Press.)

To compare the efficacy of antipsychotics (APs) for delirium treatment in patients with cancer, 27 patients treated with 1 of the 4 APs, haloperidol (HPD), risperidone (RIS), olanzapine (OLZ), and quetiapine (QTP), were divided into 2 groups: long half-life (T1/2; HPD, RIS, and OLZ) versus short T1/2 (QTP) or the multiacting receptor-targeted APs (MARTAs; OLZ and QTP) versus the non-MARTA (HPD and RIS). The symptom severity was evaluated by the memorial delirium rating scale (MDAS) on days 0, 3, and 7 following intervention. Significant improvements in total MDAS scores were found in all groups on day 3. However, on day 7, only the short T1/2 group and MARTA group showed significant improvement. Consideration of an AP's pharmacological properties may be helpful for improving the outcomes of pharmacological delirium intervention in patients with cancer., (© The Author(s) 2014.)

Cancer patients often suffer from various distresses, including cognitive impairment. Cognitive impairment during and after cancer diagnosis and treatment are collectively called "Cancer-related cognitive impairment (CRCI)". The number of publications about cognitive impairment due to cancer therapy, especially chemotherapy, hormonal therapy, and radiotherapy, has been growing. Patients often worry not only about their disease condition and therapies, but also experience concerns regarding their memory, attention, and ability to concentrate. Even subtle CRCI can have a significant impact on social relationships, the ability to work, undergo treatment, accomplish meaningful goals, and the quality of life. Longitudinal studies of cancer patients indicated that up to 75% experience CRCI during treatment. Furthermore, CRCI may persist for many years following treatment. However, it is not well understood by most physicians and medical staff. CRCI can be mediated through increased inflammatory cytokines and hormonal changes. In addition, the biology of the cancer, stress, and attentional fatigue can also contribute to CRCI. Genetic factors and co-occurring symptoms may explain some of the inter-individual variability in CRCI. Researchers and patients are actively trying to identify effective interventional methods and useful coping strategies. Many patients are willing to discuss their disease condition and future treatment with medical staff and/or their families. Some patients also hope to discuss their end-of-life care. However, it is difficult to express their will after developing cognitive impairment. Advance care planning (ACP) can help in such situations. This process involves discussion between a patient, their family, and clinicians to clarify and reflect on values, treatment preferences, and goals to develop a shared understanding of how end-of-life care should proceed. The number of cancer patients with cognitive impairment has been increasing owing to the super-aging of society. Psychiatrists need to develop appropriate care for them and understand the value of ACP. In this review, an outline of CRCI is given, especially related to cancer therapy such as chemotherapy, hormonal therapy, and radiation therapy. In addition, the importance of ACP to facilitate a living will for patients likely to develop impaired cognitive functions in the future is described.

Background: Ketamine is often used to manage neuropathic pain in patients with cancer. However, it occasionally causes psychotomimetic effects such as vivid dreams, nightmares, illusions, hallucinations, and altered body image., Objective: To examine whether gradual dose titration of ketamine for management of neuropathic pain prevents psychotomimetic effects in patients with advanced cancer., Methods: This was a retrospective chart review. We administered ketamine when neuropathic pain in patients with advanced cancer became refractory to opioids and oral adjuvant analgesics. The starting dose of ketamine was 10 mg/d by continuous intravenous infusion. The dose was gradually increased by 10 mg/d every 4 to 6 hours to 50 mg/d or until the pain was relieved. It was subsequently increased by 25 mg/d every 12 to 24 hours until the pain was relieved., Results: For this study, we enrolled 46 patients with advanced cancer. The mean age was 52.2 ± 16.9 years. The mean dose at onset of action and maximum dose of ketamine were 56 ± 58 and 272 ± 214 mg/d, respectively. The mean pain intensity (numerical rating scale) decreased significantly from 7.3 ± 2.0 to 3.5 ± 2.2 after the administration of ketamine (P < .01). The effectiveness was 69.5%. No psychotomimetic effect of less than 300 mg/d was observed during the introduction phase even though psychotropic drugs were not prescribed. Mild sedation was observed in 3 patients (7%) as the only adverse effect during the introduction phase., Conclusion: Gradual dose titration of ketamine for management of neuropathic pain can prevent psychotomimetic effects in patients with advanced cancer.

Patients with cancer often experience insomnia. Nightmares are also a strong factor that interferes with the maintenance of comfortable and satisfying sleep. However, the prevalence and standard treatment of nightmares in patients with cancer have not been established yet. We aimed to treat insomnia and nightmares with trazodone. From 2008 to 2011, trazodone was prescribed to 30 patients with cancer who reported experiencing insomnia with or without nightmares to the palliative care team in Osaka University Hospital. Effective treatment was seen in 15 patients (50%). Four patients with cancer reported having severe nightmares and 2 patients had beneficial effects, with frightening dreams transformed into acceptable ones. Trazodone may be an effective drug for the treatment of insomnia and nightmares in patients with advanced cancer.

Background: Agitated delirium is often observed in terminal patients with cancer. To clarify the risk factors for agitated delirium in terminal patients with cancer, we conducted a retrospective chart review of 126 patients with cancer who died at a university hospital in 2008., Method: As a working definition, we define agitated delirium as a score of 2 or more in item 9 of the Memorial Delirium Assessment Scale with diurnal variation., Results: The results were as follows: agitated delirium was observed in 49 (42%) of the 115 patients, and it occurred within the last week before death in 49% of the patients. Univariate analysis revealed older age, male gender, smoking history, lung cancer, diabetes, and high C-reactive protein (CRP) value as major risk factors, while dendritic analysis revealed lung cancer, high CRP value, diabetes, older age, and smoking history as key factors for predicting agitation., Conclusion: It is necessary to consider risk factors in order to categorize terminal patients with cancer into high- and low-risk groups and undertake possible counter-measures.

Background: Milnacipran is one of the classes of drugs that are serotonin and norepinephrine reuptake inhibitors (SNRIs). It is a promising drug for the treatment of neuropathic pain in patients with advanced cancer. However, we found that neuromuscular and somatosensory disorders occurred when milnacipran was used as an adjuvant analgesic., Case Report: A 66-year-old woman with a history of neuropathic pain was given 15 mg of milnacipran after dinner. The next morning she developed stiffness of the fingers, numbness in the mandible, and the soles of her feet felt swollen. Milnacipran was discontinued and her symptoms disappeared immediately. We managed this case, which was becoming severe, by discontinuing milnacipran on early detection of symptoms., Discussion: This is the first report that demonstrates an adverse reaction of milnacipran when used as an analgesic adjuvant, and not as an antidepressant drug, for neuropathic pain in patients with advanced cancer. The analgesic effect of SNRIs will likely be used in the management of neuropathic pain in the future; however, clinicians should be aware of the early adverse reactions to these agents.

Background: Appropriate use of anti-infective drugs is essential in clinical practice. No evidence-based guidelines or protocols have been published on the appropriate use of anti-infective drugs in patients receiving palliative care as yet., Methods: The medical records, which included the demographic data of patients, anti-infective drug use, bacteriologic findings, symptoms, and hematologic findings were reviewed retrospectively to determine the potential factors that contribute to symptom improvement of patients in terminal phase., Results: Seventy-one patients (64%) who received anti-infective drugs and had a total of 326 episodes of infection were assessed. Symptom improvement was seen in 33.1%. A total of 22.6% of episodes were started on anti-infective drugs during the last week of life and the symptom improvement in these episodes was 9.2%. Symptom improvement was hardly observed when the anti-infective drug was administered during the last week of life. The association between the decrease in the C-reactive protein (CRP) levels, the decrease of the leukocyte count, reduction of fever, and symptom improvement was determined. The decrease of CRP levels was 42.4%; leukocyte, 56.7%; and reduction of fever was 28.4%. The symptom improvement of individual treatment history was also investigated. The symptom improvement of the group who took positive treatment such as chemotherapy, radiotherapy, surgery, and catheter placement was significantly lower than that of no-treatment group., Conclusions: Active cancer treatment probably induces the symptoms related to infection and the use of anti-infective drugs. Unnecessary and excessive treatment should be avoided, and the symptoms should be managed with consideration of the patient's state of mind in order to improve the quality of life of terminally ill patients.

In palliative care, steroids are often used to alleviate symptoms such as pain, fatigue, anorexia, nausea, and vomiting. Steroids occasionally induce psychiatric adverse effects. It has been reported that treatment of the steroid-induced psychiatric symptoms involves dosage reduction or discontinuation of steroid, and concomitant administration of psychotropics. There were few reports on effectiveness of treatment of steroid-induced psychiatric symptoms by switching from one steroid to the other. We experienced the case of 67-year-old man with malignant pleural mesothelioma and pulmonary emphysema who developed psychiatric symptoms after switching from oral prednisolone 10 mg/day to intravenous betamethasone 2 mg/day. He began to complain that "time repeats cycles of going and coming" and that he was "unable to distinguish between daytime and night," and his face became expressionless. He gazed at familiar healthcare professionals as if seeing them for the first time, complaining: "I feel something obscure or strange in my head." He was unable to remember events on the same or the previous day at all, and made no verbal response to questions by healthcare professionals. He did not know how to eat or use the toilet, and thus required assistance in daily life activities. He did not respond even when talked to by his family members. He continued gazing at them, sometimes saying: "Where am I now? Am I sick?" He behaved restlessly, repeating cycles of lying and sitting. The symptoms disappeared gradually after re-switching from intravenous betamethasone 2 mg/day to oral prednisolone 10mg/day. "Steroid switching" may serve as a valid alternative treatment.
