Concomitant use of hydroxyzine and haloperidol did not worsen delirium in patients with cancer: A multicenter, retrospective, observational study.

OBJECTIVES: There is concern that hydroxyzine exacerbates delirium, but a recent preliminary study suggested that the combination of haloperidol and hydroxyzine was effective against delirium. This study examined whether the concomitant use of hydroxyzine and haloperidol worsened delirium in patients with cancer. METHODS: This retrospective, observational study was conducted at 2 general hospitals in Japan. The medical records of patients with cancer who received haloperidol for delirium from July to December 2020 were reviewed. The treatments for delirium included haloperidol alone or haloperidol combined with hydroxyzine. The primary outcome was the duration from the first day of haloperidol administration to the resolution of delirium, defined as its absence for 2 consecutive days. The time to delirium resolution was analyzed to compare the haloperidol group and hydroxyzine combination group using the log-rank test with the Kaplan-Meier method. Secondary outcomes were (1) the total dose of antipsychotic medications, including those other than haloperidol (measured in chlorpromazine-equivalent doses), and (2) the frequencies of detrimental incidents during delirium, specifically falls and self-removal of drip infusion lines. The unpaired t-test and Fisher's exact test were used to analyze secondary outcomes. RESULTS: Of 497 patients who received haloperidol, 118 (23.7%) also received hydroxyzine. No significant difference in time to delirium resolution was found between the haloperidol group and the hydroxyzine combination group (log-rank test, P = 0.631). No significant difference between groups was found in either chlorpromazine-equivalent doses or the frequency of detrimental incidents. SIGNIFICANCE OF RESULTS: This study showed that the concomitant use of hydroxyzine and haloperidol did not worsen delirium in patients with cancer.

Data-driven categorization of postoperative delirium symptoms using unsupervised machine learning.

Background: Phenotyping analysis that includes time course is useful for understanding the mechanisms and clinical management of postoperative delirium. However, postoperative delirium has not been fully phenotyped. Hypothesis-free categorization of heterogeneous symptoms may be useful for understanding the mechanisms underlying delirium, although evidence is currently lacking. Therefore, we aimed to explore the phenotypes of postoperative delirium following invasive cancer surgery using a data-driven approach with minimal prior knowledge. Methods: We recruited patients who underwent elective invasive cancer resection. After surgery, participants completed 5 consecutive days of delirium assessments using the Delirium Rating Scale-Revised-98 (DRS-R-98) severity scale. We categorized 65 (13 questionnaire items/day × 5 days) dimensional DRS-R-98 scores using unsupervised machine learning (K-means clustering) to derive a small set of grouped features representing distinct symptoms across all participants. We then reapplied K-means clustering to this set of grouped features to delineate multiple clusters of delirium symptoms. Results: Participants were 286 patients, of whom 91 developed delirium defined according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, criteria. Following the first K-means clustering, we derived four grouped symptom features: (1) mixed motor, (2) cognitive and higher-order thinking domain with perceptual disturbance and thought content abnormalities, (3) acute and temporal response, and (4) sleep-wake cycle disturbance. Subsequent K-means clustering permitted classification of participants into seven subgroups: (i) cognitive and higher-order thinking domain dominant delirium, (ii) prolonged delirium, (iii) acute and brief delirium, (iv) subsyndromal delirium-enriched, (v) subsyndromal delirium-enriched with insomnia, (vi) insomnia, and (vii) fit. Conclusion: We found that patients who have undergone invasive cancer resection can be delineated using unsupervised machine learning into three delirium clusters, two subsyndromal delirium clusters, and an insomnia cluster. Validation of clusters and research into the pathophysiology underlying each cluster will help to elucidate the mechanisms of postoperative delirium after invasive cancer surgery.

A revision of JPOS/JASCC clinical guidelines for delirium in adult cancer patients: a summary of recommendation statements.

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.

Prevention of delirium with agitation by yokukansan in older adults after cancer surgery.

OBJECTIVE: Preventing postoperative delirium with agitation is vital in the older population. We examined the preventive effect of yokukansan on postoperative delirium with agitation in older adult patients undergoing highly invasive cancer resection. METHODS: We performed a secondary per-protocol analysis of 149 patients' data from a previous clinical trial. Patients underwent scheduled yokukansan or placebo intervention 4-8 days presurgery and delirium assessment postoperatively. Delirium with agitation in patients aged ≥75 years was assessed using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and the Japanese version of the Delirium Rating Scale-Revised-98. We assessed odds ratios for yokukansan (TJ-54) compared with placebo for the manifestation of postoperative delirium with agitation across patients of all ages (n = 149) and those aged ≥65 years (n = 82) and ≥ 75 years (n = 21) using logistic regression. RESULTS: Delirium with agitation manifested in 3/14 and 5/7 patients in the TJ-54 and placebo groups, respectively, among those aged ≥75 years. The odds ratio for yokukansan vs. placebo was 0.11 (95% confidence interval: 0.01-0.87). An age and TJ-54 interaction effect was detected in patients with delirium with agitation. No intergroup differences were observed in patients aged ≥65 years or across all ages for delirium with agitation. CONCLUSIONS: This is the first study investigating the preventive effect of yokukansan on postoperative delirium with agitation in older adults. Yokukansan may alleviate workforce burdens in older adults caused by postoperative delirium with agitation following highly invasive cancer resection.

Pilot Study of Lemborexant for Insomnia in Cancer Patients with Delirium.

Delirium occurs very frequently in cancer patients. Insomnia is a symptom of delirium. Lemborexant is a drug that regulates sleep-wake rhythms without causing extrapyramidal symptoms. Based on its ability to improve sleep, lemborexant is expected to have efficacy for insomnia with delirium. The purpose of this study was to determine the efficacy of lemborexant for insomnia in cancer patients with delirium. A retrospective observational study was conducted between July 2020 and February 2021. Fourteen patients (six females; mean age,69 years) were included. Lemborexant was effective in 11 of 14 (78.6%) patients. Of 14 patients, 10 had hyperactive delirium. Lemborexant might have similar efficacy for insomnia with and without delirium when compared with previous studies. The efficacy rate of lemborexant was 70% for patients with insomnia and hyperactive delirium. This study might lead to dose reductions of antipsychotic medications and fewer extrapyramidal symptoms in cancer patients with delirium.

Yokukansan for Treatment of Preoperative Anxiety and Prevention of Postoperative Delirium in Cancer Patients Undergoing Highly Invasive Surgery. J-SUPPORT 1605 (ProD Study): A Randomized, Double-Blind, Placebo-Controlled Trial.

CONTEXT: No standard preventive or therapeutic methods have been established for preoperative anxiety and postoperative delirium in patients with cancer. OBJECTIVES: To clarify the therapeutic effect of yokukansan for perioperative psychiatric symptoms in patients with cancer as well as to confirm its safety profile. METHODS: This is a randomized, double-blind, and placebo-controlled trial conducted at a single center in Tokyo, Japan. About 195 patients with cancer scheduled to undergo tumor resection took one packet of the study drug, which was administered orally. Coprimary outcomes were change in preoperative anxiety assessed with the Hospital Anxiety and Depression Scale-Anxiety and incidence of postoperative delirium assessed with the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Interim analysis was performed with one-third (n = 74) of the target number of registered patients. RESULTS: Because this trial was canceled based on the results of the interim analysis and the protocol treatment was discontinued in patients who were already registered, conclusions were based on the full analysis set of 160 participants. There were no significant differences between groups in the change of mean Hospital Anxiety and Depression Scale-Anxiety score (intervention group [SD] 0.4 [3.0] vs. placebo group 0.5 [3.0]; P = 0.796) or the incidence of postoperative delirium (32% vs. 30%; P = 0.798). There were no serious adverse events in either group. CONCLUSION: In patients with cancer undergoing highly invasive surgeries, yokukansan demonstrated no significant efficacy for the treatment of preoperative anxiety or the prevention of postoperative delirium. Yokukansan is already used in daily practice in Japan, but we should be careful with its future use.

JPOS/JASCC clinical guidelines for delirium in adult cancer patients: a summary of recommendation statements.

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.

Expectations of and recommendations for a cancer survivorship guideline in Japan: a literature review of guidelines for cancer survivorship.

BACKGROUND: Optimal cancer survivorship care needs its comprehensive guidelines. We aimed to identify English and Japanese guidelines that include cancer survivorship in their title, the issues highlighted in such guidelines, and any existing oncology practice guidelines in Japan that address these issues. METHODS: This literature review was performed in three stages. First, guidelines published in English or Japanese that included cancer survivorship in the title were identified. Then, the issues that each cancer survivorship guideline addressed were defined. Lastly, Japanese guidelines that include survivorship issues were sought. RESULTS: Six guidelines published in English addressed 31 cancer survivorship issues. No specific cancer survivorship guideline was available in Japanese. Thirty-four Japanese guidelines mentioned cancer survivorship issues. These guidelines addressed screening/surveillance for detecting recurrence or secondary cancer but did not address coordination of care, implications for practice, or inclusion of family. At present, Japanese guidelines poorly address the issue of promotion of a healthy lifestyle in cancer survivors. Also, poorly addressed were long-term and late effects such as pain, psychological distress, fatigue, cognitive dysfunction, cardiovascular effects (including anthracycline-induced cardiac toxicity), sleep disorders, and sexual dysfunction in cancer survivors. CONCLUSION: There is a need for guidelines on optimal coordination of care between oncologists and other health care providers to support patients along the cancer care continuum and specifically to encourage a healthy lifestyle as part of cancer survivorship. The development of a comprehensive Japanese guideline that addresses these issues would help to improve the clinical outcome for cancer survivors in Japan.

Yokukansan for perioperative psychiatric symptoms in cancer patients undergoing high invasive surgery. J-SUPPORT 1605 (ProD Study): study protocol for a randomized controlled trial.

BACKGROUND: Preoperative anxiety and postoperative delirium affect both short- and long-term prognoses in patients with cancer; therefore, these conditions require early prevention and treatment. However, no standard preventive or therapeutic methods have been established for them. Yokukansan, a Japanese herbal medicine for the treatment of insomnia and anxiety, causes relatively few adverse drug reactions and effectively improves the behavioral and psychological symptoms of dementia. Thus, it is expected to be useful for treating and/or preventing perioperative psychiatric symptoms in patients with cancer. The objective of this study is to clarify the therapeutic effect of Yokukansan for preoperative anxiety and its preventive effect on postoperative delirium in cancer patients, as well as to confirm its safety profile. METHODS: This study is a randomized, double-blind, placebo-controlled study in cancer patients scheduled to undergo tumor resection. Patients who provide consent are randomly allocated to receive oral administration of Yokukansan or placebo, and study drug administration is continued for 4 days or longer prior to surgery. We defined two primary endpoints, change in preoperative anxiety and incidence of postoperative delirium. Secondary endpoints are severity score of postoperative delirium, duration of postoperative delirium, amount of benzodiazepines used prior to surgery, amount of antipsychotic agents used after surgery, and number of postoperative hospitalization days. We plan to complete the analysis on March 31, 2021. The target number of registered patients is 110 per group, or 220 in total. DISCUSSION: This study is the first randomized, double-blind, placebo-controlled study intended to clarify the effects of a Japanese herbal medicine, Yokukansan, in the prevention and treatment of perioperative psychiatric symptoms in patients with cancer. The trial was initiated on August 14, 2017, with 195 subjects randomized by October 5, 2018. TRIAL REGISTRATION: UMIN Clinical Trials Registry (UMIN-CTR), UMIN000027561 . Registered on 31 May 2017.

Preoperative Anxiety as a Predictor of Delirium in Cancer Patients: A Prospective Observational Cohort Study.

BACKGROUND: Postoperative delirium is a common and important complication in cancer patients. We need to identify patients at high risk of postoperative delirium such that it can be prevented preoperatively or in early postoperative phase. The aim of this study was to investigate whether preoperative anxiety predicted onset of postoperative delirium in cancer patients, not only in order to identify high-risk groups but also to help develop new preventive approaches. METHODS: This was a prospective observational cohort study of cancer patients undergoing tumor resections. Postoperative delirium was assessed using the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5). Preoperative anxiety was evaluated with the Hospital Anxiety and Depression Scale-Anxiety (HADS-A), and we defined HADS-A > 7 as clinical anxiety. We conducted multivariate logistic regression to determine which factors were predictors of delirium. RESULTS: The final analysis included 91 patients, 29 of whom met the criteria for postoperative delirium. In multivariable logistic regression, age (5-year increments; odds ratio (OR) = 1.565, 95% confidence interval (CI) = 1.057-2.317, p = 0.025) and HADS-A > 7 (OR = 4.370, 95% CI = 1.051-18.178, p = 0.043) predicted delirium onset. These variables explained 74.2% of the variance. CONCLUSIONS: Preoperative anxiety strongly predicted postoperative delirium in cancer patients. Our findings suggest that preoperative anxiety may be a new target for prevention of postoperative delirium. Trial registration number This study was registered at UMIN000018980.

Yokukansan for the treatment of preoperative anxiety and postoperative delirium in colorectal cancer patients: a retrospective study.

BACKGROUND: Yokukansan (YKS), a Japanese traditional herbal medicine for neurosis and insomnia, is speculated to be useful for perioperative psychiatric symptoms in cancer patients, but there exists little empirical evidence. This study provides preliminary data about the efficacy, feasibility, and side effects of YKS for the treatment of preoperative anxiety and postoperative delirium in cancer patients. METHODS: We retrospectively reviewed the medical records of colorectal cancer patients who took YKS for preoperative anxiety, evaluating the following: (1) patient characteristics, (2) feasibility of taking YKS, (3) changes in preoperative anxiety based on the Clinical Global Impression (CGI) scale and Edmonton Symptom Assessment System-revised (ESAS-r-anxiety), (4) incidence of postoperative delirium and (5) YKS-related side effects. RESULTS: We reviewed 19 medical records. There was a significant difference between ESAS-r-anxiety scores (P = 0.028) before and after taking YKS, but no difference between CGI scores (P = 0.056). The incidence of postoperative delirium was 5.2% (95% CI = 0.0-14.5). One patient could not complete the course of YKS during the perioperative administration period, but there were no side effects of Grade 2 or worse according to the Common Terminology Criteria for Adverse Events v4. CONCLUSIONS: Cancer patients could safely take YKS before surgery. There was a significant improvement in preoperative anxiety after taking YKS, and the incident rate of postoperative delirium was lower than in previous studies. These results suggest that YKS may be useful for perioperative psychiatric symptoms in cancer patients. Further well-designed studies are needed to substantiate our results.

Physicians' practice of discussing fertility preservation with cancer patients and the associated attitudes and barriers.

PURPOSE: The aim of this study is to describe physicians' clinical practice of discussing fertility issues with cancer patients and determine the factors associated with such discussion. METHODS: In this cross-sectional study, a nationwide Internet survey was conducted among physicians who provided daily medical care to cancer patients at hospitals or clinics. Participants answered a questionnaire assessing characteristics, discussion practices, attitudes, and barriers regarding fertility preservation. RESULTS: Among the 180 participants, 42% discussed fertility issues with patients daily, and 30% had experience in referring patients to fertility preservation specialists. A multivariate logistic regression analysis showed that those who agreed or strongly agreed with the statements "physicians are responsible for discussing fertility preservation" (OR = 2.04, 95% CI 1.14-3.63, p < 0.05) and "patients who have an exceedingly aggressive disease and need immediate cancer treatment should not be told about fertility issues" (OR =1.84, 95% CI 1.09-3.10, p < 0.05) were nearly twice as likely to discuss fertility issues with patients. CONCLUSIONS: Compared to Western countries, fertility issues are less likely to be discussed in Japan. To increase opportunities for patients to discuss fertility issues, the ASCO guidelines should be widely understood. Additionally, these results suggest that physicians who are more likely to discuss fertility issues might feel more conflicted about whether they in fact should discuss such issues with patients with poor prognosis or insufficient time for cancer treatment.

The Association Between Depressive Symptoms and Age in Cancer Patients: A Multicenter Cross-Sectional Study.

CONTEXT: There is controversy around the association between depressive symptoms and age in adult cancer patients. OBJECTIVES: The aim of this study was to evaluate the following hypotheses: 1) cancer patients' depressive symptoms decrease with age, and 2) in individuals aged 65 years or older, depressive symptoms increase because of the effect of somatic symptoms. METHODS: We retrospectively analyzed a database of 356 cancer patients who were consecutively recruited in a previous multicenter cross-sectional study. Depressive symptoms were assessed by the Patient Health Questionnaire-9 (PHQ-9), and correlations with age and other factors were assessed by hierarchical multivariate regression analysis. Age was entered as the dependent variable in the first step, patient characteristics and cancer-related variables were entered in the second step, and somatic symptoms were entered in the last step. We analyzed this model for both the total sample and the subpopulation aged 65 years or older. RESULTS: In the total sample, the PHQ-9 score was significantly associated with lower age, fatigue, and shortness of breath (adjusted R(2) 14.2%). In the subpopulation aged 65 years or older, no factor was associated with the PHQ-9 score (adjusted R(2) 7.3%). CONCLUSION: The finding that depressive symptoms in cancer patients decreased with age was concordant with our first hypothesis, but the second hypothesis was not supported. Younger cancer patients were vulnerable to depressive symptoms and should be monitored carefully. Further studies using more representative samples are needed to examine in detail the association between depressive symptoms and age in older cancer patients.

F-18 FDG PET/CT imaging of bulky myxofibrosarcoma in chest wall.

Myxofibrosarcoma (MFS) has a spectrum of malignant fibroblastic lesions with variably myxoid stroma and pleomorphism. A 67-year-old man with a bulky mass on his chest wall was diagnosed with MFS. He underwent F-18 fluorodeoxyglucose (FDG) positron emission tomography/computed tomography for detection of metastasis. FDG positron emission tomography /computed tomography showed inhomogeneous high FDG uptake (max standardized uptake value, 10.1) in the bulky tumor with no evidence of metastasis, and the tumor was successfully resected. FDG uptake seemed to be reflected by the broad spectrum of pathologic heterogeneity. And MFS should be considered when making a diagnosis of inhomogeneous FDG-avid lesions in the bulky masses of soft tissue.
