Associations of nutrition impact symptoms with dietary intake and eating-related distress in patients with advanced cancer.

BACKGROUND & AIMS: There is no definition of nutrition impact symptoms (NISs) in cancer care. Moreover, there is a lack of evidence on the associations of NISs with dietary intake and eating-related distress (ERD) in advanced cancer. Therefore, this study aimed to determine the associations of NISs with dietary intake and ERD in patients with advanced cancer. METHODS: This study entailed a secondary analysis of a multicenter self-reported questionnaire designed to develop measurements that assess ERD experienced by patients. Participants evaluated their dietary intake and 19 symptoms regarded as NISs using a 10-point scale. To determine the association between dietary intake and the number of NISs with a score ≥4, estimated adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the logistic regression model were calculated. Furthermore, to assess the association between ERD and the number of NISs with a score ≥4, multiple regression analysis was performed. RESULTS: A total of 302 patients were included in the analysis. The higher the number of NISs with a score ≥4, the lower the dietary intake tended to be. In the logistic regression model, significantly higher adjusted ORs than in the no NISs with a score ≥4 group were observed in the 4-6 NISs group, 7-9 NISs group, and 10 or more group (0.19 [95% CI, 0.07-0.52], p = 0.001; 0.11 [95% CI, 0.03-0.42], p = 0.001; 0.07 [95% CI, 0.01-0.36], p = 0.002, respectively). In the multiple regression analysis, the number of NISs with a score ≥4 was identified as one of the factors significantly associated with ERD. CONCLUSIONS: Having 4 or more NISs with a score ≥4 was shown to be predictive of the likelihood of reduced dietary intake. Furthermore, the higher the number of NISs with a score ≥4, the more likely the eating-related quality of life was impaired in advanced cancer.

Impacts of fluid retention on prognostic abilities of cachexia diagnostic criteria in cancer patients with refractory cachexia.

BACKGROUND & AIMS: The international cancer cachexia criteria with a cutoff of 5% weight loss (WL) was proposed in Western patients. The Asian Working Group for Cachexia (AWGC) developed new criteria in Asian patients. The AWGC criteria are not cancer-specific and employ a cutoff of 2% WL. However, it is unclear whether both criteria are useful in patients with very advanced cancer because WL can be underestimated owing to fluid retention. Therefore, this study aimed to investigate the impacts of fluid retention on the prognostic abilities of both criteria in cancer patients with weeks of survival. METHODS: This study involved a secondary analysis of a prospective cohort study. The inclusion criteria constrained the study to adult patients with advanced cancer. Patients were divided into Non-cachexia and Cachexia groups using the international criteria and AWGC criteria. We performed time-to-event analyses using the Kaplan-Meier method and log-rank tests, and by conducting univariate and multivariate Cox regression analyses. RESULTS: A total of 402 patients were included in the analysis. Using the international criteria, the p-values for the log-rank test and stratified log-rank test for the mixed patients with and without fluid retention were 0.55 and 0.18, respectively. Using the AWGC criteria, the p-values for the log-rank test and stratified log-rank test for the mixed patients with and without fluid retention were 0.38 and 0.12, respectively. Without considering the impacts of fluid retention, no significant differences were observed between the Non-cachexia and Cachexia groups for both criteria. After adjusting for the status of fluid retention, significantly higher risks of mortality were not observed in the Cox proportional hazard model for the Cachexia group compared with the Non-cachexia group, for both criteria. However, significant associations were observed between fluid retention and overall survival. CONCLUSIONS: The international criteria and AWGC criteria lost their prognostic abilities in cancer patients with weeks of survival. Since measurements of %WL were significantly confounded by fluid retention, fluid retention-adjusted criteria for cachexia need to be developed for cancer patients with refractory cachexia.

Factors associated with multimodal care practices for cancer cachexia among registered dietitians.

PURPOSE: This study aimed to determine factors associated with multimodal care practices for cancer cachexia among registered dietitians (RDs) working in cancer care. METHODS: A secondary analysis was performed using RDs' data. Data on knowledge, skills, and confidence in multimodal care were obtained. Nine items regarding multimodal care practices were evaluated. Subjects were divided into two groups based on their answers associated with the nine items. Comparisons were obtained using the Mann-Whitney U test or chi-squared test. Multiple regression analysis was performed to identify the critical factors involved in practicing multimodal care by determining the variables with significant differences between the two groups. RESULTS: Two hundred thirty-two RDs were included in this study. Significant differences were observed in their primary area of practice (p = 0.023), the number of clinical guidelines used (p < 0.001), the number of items used in cancer cachexia assessment (p = 0.002), the number of symptoms used in cancer cachexia assessment (p = 0.039), training for cancer cachexia (p < 0.001), knowledge of cancer cachexia (p < 0.001), and confidence in cancer cachexia management (p < 0.001). The number of symptoms used in cancer cachexia assessment (B = 0.42, p = 0.019), knowledge of cancer cachexia (B = 6.60, p < 0.001), and confidence in cancer cachexia management (B = 4.31, p = 0.010) were identified as critical factors according to the multiple regression analysis. CONCLUSION: The RDs' knowledge and confidence in cancer cachexia management were associated with their multimodal care practices.

Investigating the efficacy and safety of olanzapine prophylaxis for opioid-induced nausea and vomiting (JORTC-PAL20): a study protocol for an open-label, single-arm exploratory study.

INTRODUCTION: In opioid therapy for cancer pain, opioid-induced nausea and vomiting (OINV) occur in 20%-40% of patients during initial opioid treatment or increasing opioid doses. OINV result in failure to achieve pain relief due to poor opioid adherence. Therefore, antiemetics are used to prevent OINV, but their efficacy and safety in this context have not yet been fully elucidated. Olanzapine is a promising antiemetic for the prophylaxis of chemotherapy-induced nausea and vomiting. METHODS AND ANALYSIS: This single-arm, single-centre exploratory study will evaluate the prophylactic antiemetic efficacy and safety of 5 mg olanzapine in patients with cancer pain who are withholding initial regular opioid therapy. Thirty-five patients will be enrolled. The primary endpoint is the proportion of patients achieving complete control (CC) of OINV during 5 days of opioid treatment. CC was defined as the absence of emetic episodes, no need for rescue medication to treat nausea, and minimal or no nausea (3 or less on an 11-point categorical scale). Secondary endpoints include the complete response, defined as no emetic episodes and no use of rescue medication during the overall assessment period, the time from opioid initiation to first emetic episode, the time from opioid initiation to first rescue antiemetic administration, and adverse events graded by Patient-Reported Outcome (PRO) Common Terminology Criteria for Adverse Events (CTCAE) version 1.0 and CTCAE version 5.0. ETHICS AND DISSEMINATION: This study protocol was approved by National Cancer Center Hospital Certified Review Board. The results will be used as preliminary data to conduct a validation study. TRIAL REGISTRATION NUMBER: Japan Registry of Clinical Trials (jRCT) jRCTs031220008.

Fluid retention and weight loss in refractory cancer cachexia.

OBJECTIVES: It is unknown to what extent the fluid retention (FR) status disrupts the detection of weight loss rate (WLR) in adult patients with advanced cancer. This study aimed to determine the association of FR status with WLR. METHODS: This study was a secondary analysis of a prospective cohort study. FR was evaluated as follows: oedema (0, no; 1, yes), pleural effusion (0, no; 1, yes but asymptomatic; 2, symptomatic) and ascites (0, no; 1, yes but asymptomatic; 2, symptomatic). Patients were divided into three groups according to their FR scores: no-FR (0), moderate-FR (1-2) and high-FR (3-5). Multiple regression analysis was performed. RESULTS: Four hundred and twenty patients were categorised: no-FR group (n=164), moderate-FR group (n=158) and high-FR group (n=98). The prevalence of oedema, pleural effusion and ascites was 63.9%, 27.8% and 36.7% in the moderate-FR group, and 93.9%, 61.3% and 82.6% in high-FR group. The means of WLR were 9.2, 8.4 and 3.8 in the groups. The high-FR group and the FR score of 5 were correlated with WLR (estimate -4.71, 95% CI -7.84 to -1.58; estimate -10.29, 95% CI -17.84 to -2.74). CONCLUSIONS: The coexistence of FR was significantly correlated with WLR.

Effectiveness of antipsychotics for managing agitated delirium in patients with advanced cancer: a secondary analysis of a multicenter prospective observational study in Japan (Phase-R).

PURPOSE: Delirium is a common and serious comorbidity in patients with advanced cancer, necessitating effective management. Nonetheless, effective drugs for managing agitated delirium in patients with advanced cancer remain unclear in real-world settings. Thus, the present study aimed to explore an effective pharmacotherapy for this condition. METHODS: We conducted a secondary analysis of a multicenter prospective observational study in Japan. The analysis included patients with advanced cancer who presented with agitated delirium and received pharmacotherapy. Agitation was defined as a score of the Richmond Agitation-Sedation Scale for palliative care (RASS-PAL) of ≥ 1. The outcome was defined as -2 ≤ RASS-PAL ≤ 0 at 72 h after the initiation of pharmacotherapy. Multiple propensity scores were quantified using a multinomial logistic regression model, and adjusted odds ratios (ORs) were calculated for haloperidol, chlorpromazine, olanzapine, quetiapine, and risperidone. RESULTS: The analysis included 271 patients with agitated delirium, and 87 (32%) showed -2 ≤ RASS-PAL ≤ 0 on day 3. The propensity score-adjusted OR of olanzapine was statistically significant (OR, 2.91; 95% confidence interval, 1.12 to 7.80; P = 0.030). CONCLUSIONS: The findings suggest that olanzapine may effectively improve delirium agitation in patients with advanced cancer.

Psychological symptom burden associated with malignant wounds: Secondary analysis of a prospective cohort study.

OBJECTIVES: Patients with malignant wounds suffer from physical and psychological symptom burden. Despite psychological support being required, the impact of malignant wounds on patients' psychological distress is poorly investigated. We evaluated psychological distress associated with malignant wounds for patients at their end of life. METHODS: This study used the secondary analysis of the results of a large prospective cohort study, which investigated the dying process among patients with advanced cancer in 23 palliative care units in Japan. The primary outcome of this study was the prevalence of moderate to severe psychological symptom burden, evaluated by the Integrated Palliative Care Outcome Scale (IPOS)-feeling at peace scores of 2-4. In addition, the factors affecting psychological symptoms were investigated. The quality of death was also evaluated upon death using the Good Death Scale score. RESULTS: Out of the total 1896 patients, 156 had malignant wounds (8.2%). Malignant wounds were more common in female and young people. The breast, head, and neck were the most prevalent primary sites. More patients with malignant wounds had IPOS-feeling at peace scores of 2-4 than patients without malignant wounds (41.0% vs. 31.3%, p = 0.024). Furthermore, psychological distress was associated with moderate to severe IPOS-pain and the frequency of dressing changes. The presence of malignant wounds did not affect the quality of death. SIGNIFICANCE OF RESULTS: This study showed increased psychological distress due to malignant wounds. Patients with malignant wounds require psychological support in addition to the treatment of physical symptoms for maintaining their quality of life.

Validity of the diagnostic criteria from the Asian Working Group for Cachexia in advanced cancer.

BACKGROUND: Recently, the Asian Working Group for Cachexia (AWGC) published a consensus statement on diagnostic criteria for cachexia in Asians. We aimed to validate the criteria in adult patients in Japan with advanced cancer. METHODS: We conducted a single-institution retrospective cohort study between April 2021 and October 2022. The AWGC criteria include chronic comorbidities and either a weight loss of >2% over 3-6 months or a body mass index (BMI) of <21 kg/m2 . In addition, any of the following items were required: anorexia as a subjective symptom, decreased grip strength as an objective measurement and an elevated C-reactive protein (CRP) level as a biomarker. We used the cut-off value of grip strength of 28/18 kg for male/female individuals and CRP level of 5 mg/L. RESULTS: Of the 449 consecutive patients, 85 of those who could not be evaluated because of end-of-life or refractory symptoms (n = 41) or missing data (n = 44) were excluded from the primary analysis. The prevalence of the AWGC-defined cachexia was 76% (n = 277), and the median survival time (MST) for all patients was 215 (95% confidence interval [CI] 145-270) days. The prevalence of the following criteria was significantly higher in patients with cachexia than in those without cachexia: a BMI of <21 kg/m2 (65% vs. 15%, P < 0.001), a weight loss of >2% in 6 months (87% vs. 14%, P < 0.001), anorexia (75% vs. 47%, P < 0.001), a grip strength of <28 kg in male individuals (63% vs. 28%, P < 0.001) and CRP level of >5 mg/L (85% vs. 56%, P < 0.001). Overall survival was significantly shorter in patients with cachexia than in those without cachexia (MST 157 days, 95% CI 108-226 days vs. MST 423 days, 95% CI 245 days to not available, P = 0.0023). The Cox proportional hazards analysis showed that best supportive care (hazard ratio [HR] 2.91, P ≤ 0.001), lung cancer (HR 1.67, P = 0.0046), an Eastern Cooperative Oncology Group Performance Status score of ≥3 (HR 1.58, P = 0.016), AWGC-defined cachexia (HR 1.56, P = 0.015), an age of ≥70 years (HR 1.53, P = 0.0070), oedema (HR 1.31, P = 0.022) and head/neck cancer (HR 0.44, P = 0.023) were found to be the significant predictors for mortality. CONCLUSIONS: We demonstrated that AWGC-defined cachexia has a significant prognostic value in advanced cancer.

Life-cycle analysis of environmental loads from household septic systems in Japan focusing on effluent water discharge.

Various types of small-scale wastewater treatment systems are widely used in rural areas, and life-cycle assessment (LCA) should be performed to evaluate their environmental performance. In this study, septic systems were first classified into five categories based on their wastewater treatment performance. Effluent samples from actual systems were collected, and their water qualities were determined. A model to evaluate the environmental load from the septic systems using LCA methods was then established. The water-quality values obtained were input to the model, and the life-cycle environmental costs of the classified septic systems were calculated. The mean environmental load of the effluent during the operation stage was 37.6%, confirming that evaluation of an effluent discharge inventory using LCA, inspection, and water-quality monitoring to improve operations is critical for reducing the environmental load. The operation stage accounts for over 99% of the involved eutrophication, biological toxicity, and toxic chemicals, which are strongly related to the quality of the effluent. Evaluation of the effluent discharge inventory using LCA is of great significance, even for small-scale wastewater treatment systems. The set of procedures developed in this study can be used to calculate comprehensive environmental impacts at wastewater treatment plants.

Low serum creatinine as a prognostic marker in advanced cancer.

OBJECTIVES: To evaluate whether low serum creatinine levels are associated with poor outcomes in patients with advanced cancer. METHODS: This is a secondary analysis of a prospective cohort study. Patients were divided into three groups according to their baseline serum creatinine levels. We performed time-to-event analyses using the Kaplan-Meier method and log-rank tests, and by conducting univariate and multivariate Cox regression analyses. RESULTS: 809 males were divided: male-low group (n=192), male-normal group (n=403) and male-high group (n=214). 808 females were divided: female-low group (n=239), female-normal group (n=389) and female-high group (n=180). Significant differences were observed in survival rates between the high and normal groups in the males and females (both log-rank p<0.001). Significantly higher risks of mortality were observed in the Cox proportional hazard model for the high group than for the normal group in both sexes (adjusted HR 1.292, 95% CI 1.082 to 1.542; adjusted HR 1.316, 95% CI 1.094 to 1.583, respectively). High serum creatinine was associated with shorter survival than normal creatinine, while low serum creatinine was not. CONCLUSIONS: Low serum creatinine levels did not have prognostic abilities in this population.

Psychosocial Factors and the Need for Multidisciplinary Support in Nutrition Counselling for Cancer Chemotherapy Patients.

This study aims to identify the background factors and experiences of patients with cancer with eating-related problems who require nutrition counselling. Using a mixed-methods approach, this secondary analysis study was conducted on patients with head and neck, oesophageal, gastric, colorectal, or lung cancers who were receiving outpatient chemotherapy. They completed a questionnaire measuring nutrition impact symptoms, eating-related distress, and quality of life (QOL). Patients who required nutrition counselling were interviewed to identify the specific issues they experienced. We reported on nutritional status and nutrition impact symptoms in a previous study. Of the 151 participants, 42 required nutrition counselling. Background factors associated with nutrition counselling were related to the following psychosocial variables: small number of people in the household, undergoing treatment while working, low QOL, and eating-related distress. Four themes were extracted from the specific issues experienced by patients: motivation for self-management, distress from symptoms, seeking understanding and sympathy, and anxiety and confusion. The desire for nutrition counselling was attributable to 'anxiety caused by the symptoms' and 'confusion about the information on eating'. Healthcare professionals should promote multidisciplinary collaboration after considering the factors associated with the required nutrition counselling to provide nutritional support.

Difficulty swallowing and food bolus obstruction in advanced cancer: association with the cachexia-related quality of life.

BACKGROUND: Swallowing disorders including difficulty swallowing and food bolus obstruction, result in reduced dietary intake-a common occurrence that leads to cachexia in patients with advanced cancer. This study examined the effects of swallowing difficulty and food bolus obstruction on cachexia-related quality of life (QOL). METHODS: This study secondarily analyzed data from a self-reported questionnaire survey of adult patients with advanced cancer at 11 palliative care services. Difficulty swallowing and food bolus obstruction were measured using the 11-point Numeric Rating Scale (NRS), whereas dietary intake and cachexia-related QOL were assessed using the Ingesta-Verbal/Visual Analog Scale and the Functional Assessment of Anorexia/Cachexia Therapy Anorexia/Cachexia Subscale. A multiple logistic regression model was employed to determine the factors associated with varying degrees of difficulty swallowing and food bolus obstruction. RESULTS: Of the invited 495 patients, 378 agreed to participate (response rate 76.4%). After excluding participants with missing data, the data of 332 participants were analyzed; 26.5% had difficulty swallowing (NRS ≥1) and 28.3% had food bolus obstruction (NRS ≥1). Multivariate analysis revealed a substantial association between difficulty swallowing and food bolus obstruction and a decrease in cachexia-related QOL, regardless of performance status and the existence of cachexia. The coefficients for difficulty swallowing and food bolus obstruction were -6.34 [95% confidence interval (CI): -9.55 to -3.14, P<0.001] and -5.88 (95% CI: -8.68 to -3.09, P<0.001), respectively. CONCLUSIONS: Cachexia-related QOL deteriorated as difficulty swallowing and food bolus obstruction worsened; thus, healthcare providers must diagnose and treat swallowing disorders in a timely manner to prevent progression of cachexia and improve cachexia-related QOL.

Factors Associated With Practice of Multimodal Care for Cancer Cachexia Among Physicians and Nurses Engaging in Cancer Care.

PURPOSE: Multimodal care for cancer cachexia is needed. This study examined factors associated with practicing multimodal cachexia care among physicians and nurses engaging in cancer care. METHODS: This was a preplanned secondary analysis of a survey investigating clinicians' perspectives on cancer cachexia. Data of physicians and nurses were used. Data on knowledge, skills, and confidence in multimodal cachexia care were obtained. Nine items on practicing multimodal cachexia care were evaluated. Participants were divided into two groups as practicing multimodal cachexia care (above median value for the nine items) or not. Comparisons were made using the Mann-Whitney U test or chi-square test. Multiple regression analysis was performed to identify the factors of practicing the multimodal care. RESULTS: Total of 233 physicians and 245 nurses were included. Significant differences were observed between the groups: female sex (P = .025), palliative care versus oncology specialization (P < .001), the number of clinical guidelines used (P < .001), the number of symptoms used (P = .005), training for cancer cachexia (P = .008), knowledge on cancer cachexia (P < .001), and confidence in cancer cachexia management (P < .001). Palliative care specialization (partial regression coefficient [B] = 0.85; P < .001), the number of clinical guidelines used (B = 0.44; P < .001), knowledge on cancer cachexia (B, 0.94; P < .001), and confidence in cancer cachexia management (B = 1.59; P < .001) were statistically significant in multiple regression analysis. CONCLUSION: Specialization in palliative care, specific knowledge, and confidence were associated with the practice of multimodal care for cancer cachexia.

Malignancy-related ascites in palliative care units: prognostic factor analysis.

OBJECTIVES: The prognostic factors in patients with malignancy-related ascites (MA) have been poorly investigated. This study aimed to evaluate both the prognostic impact of MA on terminally ill patients with cancer and the prognostic factors in those with MA. METHODS: This was a post hoc analysis of a multicentre, prospective cohort study. Patients with advanced cancer admitted to palliative care units at 23 institutions and aged≥18 years were enrolled between January and December 2017. Overall survival (OS) was compared according to MA. A multivariate analysis was conducted to explore prognostic factors in patients with MA. RESULTS: Of 1896 eligible patients, gastrointestinal and hepatobiliary pancreatic cancers accounted for 42.5%. 568 (30.0%) of the total had MA. Patients with MA had significantly shorter OS than those without MA (median, 14 vs 22 days, respectively; HR, 1.55; 95% CI, 1.39 to 1.72; p<0.01). A multivariate analysis showed that MA was a poor prognostic factor (HR, 1.30; 95% CI, 1.13 to 1.50; p<0.01) and that among patients with MA, significant poor prognostic factors were liver metastasis, moderately to severely reduced oral intake, delirium, oedema, gastric cancer, high serum creatinine, high serum C reactive protein, high serum total bilirubin, dyspnoea and fatigue, while significant good prognostic factors were female sex, good performance status, high serum albumin and colorectal cancer. CONCLUSIONS: MA had a negative impact on survival in terminally ill patients with cancer. A multivariate analysis revealed several prognostic factors in patients with terminal cancer and MA.

Hyperdry Human Amniotic Membrane as a Protective Dressing for Open Wounds With Exposed Bowel in Mice.

INTRODUCTION: An enteroatmospheric fistula forms when the exposed bowel is perforated with chronic enteric fistula formation. Currently, there is no established preventative method for this condition. Hyperdry (HD) amniotic membrane (AM) can promote early granulation tissue formation on the exposed viscera and is suitable for dressing intractable wounds as it possesses anti-inflammatory, antibacterial, and immunomodulatory properties. This study investigated whether HD-AM promotes early formation of blood vessel-containing granulation tissue for enteroatmospheric fistula treatment. METHODS: An experimental animal model of an open wound with exposed bowel was developed. A 15 × 20 mm wound was prepared on the abdomen of Institute of Cancer Research mice, and the HD-AM was placed. The mice were assigned to one of the following groups: HD-AM group, in which the stromal layer of the HD-AM was placed in contact with the exposed bowel; HD-AM UD group, in which the epithelial layer of the HD-AM was placed in contact with the exposed bowel; and the HD-AM (-) or control group, in which the HD-AM was not used. RESULTS: On postoperative days 7 and 14, granulation tissue thickness significantly increased in the HD-AM and HD-AM UD groups compared with that in the HD-AM (-) group. Macrophages accumulated in the HD-AM epithelium only in the HD-AM group. During HD-AM contact, a subset of invading macrophages switched from M1 to M2 phenotype. CONCLUSIONS: HD-AM is a practical wound dressing with its scaffolding function, regulation of TGF ß-1 and C-X-C motif chemokine 5 (CXCL-5), and ability to induce M1-to-M2 macrophage conversion.

MASCC guideline: cannabis for cancer-related pain and risk of harms and adverse events.

BACKGROUND: Approximately 18% of patients with cancer use cannabis at one time as palliation or treatment for their cancer. We performed a systematic review of randomized cannabis cancer trials to establish a guideline for its use in pain and to summarize the risk of harm and adverse events when used for any indication in cancer patients. METHODS: A systematic review of randomized trials with or without meta-analysis was carried out from MEDLINE, CCTR, Embase, and PsychINFO. The search involved randomized trials of cannabis in cancer patients. The search ended on November 12, 2021. The Jadad grading system was used for grading quality. Inclusion criteria for articles were randomized trials or systematic reviews of randomized trials of cannabinoids versus either placebo or active comparator explicitly in adult patients with cancer. RESULTS: Thirty-four systematic reviews and randomized trials met the eligibility criteria for cancer pain. Seven were randomized trials involving patients with cancer pain. Two trials had positive primary endpoints, which could not be reproduced in similarly designed trials. High-quality systematic reviews with meta-analyses found little evidence that cannabinoids are an effective adjuvant or analgesic to cancer pain. Seven systematic reviews and randomized trials related to harms and adverse events were included. There was inconsistent evidence about the types and levels of harm patients may experience when using cannabinoids. CONCLUSION: The MASCC panel recommends against the use of cannabinoids as an adjuvant analgesic for cancer pain and suggests that the potential risk of harm and adverse events be carefully considered for all cancer patients, particularly with treatment with a checkpoint inhibitor.

Multinational Association of Supportive Care in Cancer (MASCC) guidelines: cannabis for psychological symptoms including insomnia, anxiety, and depression.

PURPOSE: During the treatment of cancer, 18% of patients use cannabis for symptom management. Anxiety, depression, and sleep disturbances are common symptoms in cancer. A systematic review of the evidence for cannabis use for psychological symptoms in cancer patients was undertaken to develop a guideline. METHODS: A literature search of randomized trials and systematic reviews was undertaken up to November 12, 2021. Studies were independently assessed for evidence by two authors and then evaluated by all authors for approval. The literature search involved MEDLINE, CCTR, EMBASE, and PsychINFO databases. Inclusion criteria included randomized control trials and systematic reviews on cannabis versus placebo or active comparator in patients with cancer and psychological symptom management (anxiety, depression, and insomnia). RESULTS: The search yielded 829 articles; 145 from Medline, 419 from Embase, 62 from PsychINFO, and 203 from CCTR. Two systematic reviews and 15 randomized trials (4 on sleep, 5 on mood, 6 on both) met eligibility criteria. However, no studies specifically assessed the efficacy of cannabis on psychological symptoms as primary outcomes in cancer patients. The studies varied widely in terms of interventions, control, duration, and outcome measures. Six of 15 RCTs suggested benefits (five for sleep, one for mood). CONCLUSION: There is no high-quality evidence to recommend the use of cannabis as an intervention for psychological symptoms in patients with cancer until more high-quality research demonstrates benefit.

Perspectives of registered dietitians and factors associated with their personal accomplishment in the management of cancer cachexia.

PURPOSE: Registered dietitians (RDs) have the potential in cancer cachexia management. We investigated RDs' knowledge on cancer cachexia and assessed the effects of factors on RDs' perception of playing an important role in cancer cachexia management. METHODS: This is a secondary analysis of a survey examining the perspectives of health care professionals on cancer cachexia management. We sent the questionnaire to 451 RDs. RDs were divided into two groups: RDs with and without the perception. Comparisons were made using the Mann-Whitney U test or chi-square test. To examine the effects of factors on the perception, estimated crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the logistic regression model were calculated. RESULTS: A total of 237 RDs were analyzed. Significant differences were observed in the number of cancer patients/month, the primary area of practice, the number of clinical guidelines used, the number of items used, the number of symptoms used, and training for cancer cachexia management (p values all < 0.05). After adjustments, the factors of cancer care experience ≥ 20 years (OR 8.32, 95% CI 1.22-56.70; p = 0.030), the number of patients/month ≥ 50 (OR 27.35, 95% CI 3.99-187.24; p = 0.001), using the clinical guidelines (OR 2.69, 95% CI 1.29-5.61; p = 0.008), the number of items ≥ 5 (OR 3.52, 95% CI 1.47-8.40; p = 0.005), and receiving training (OR 3.91, 95% CI 1.77-8.67; p = 0.001) significantly associated with the perception. CONCLUSION: Specific knowledge and training as well as abundant experience were associated with the perception.

Impact of taste/smell disturbances on dietary intakes and cachexia-related quality of life in patients with advanced cancer.

PURPOSE: Taste and smell are used to enjoy meals; however, impairments of these sensory perceptions seriously impact health and eating habits. This study is aimed at investigating the impact of taste and smell disturbances on dietary intakes and cachexia-related quality of life (QOL) in patients with advanced cancer. METHODS: Using a self-report questionnaire, we surveyed patients with advanced cancer undergoing treatment at 11 palliative care centers. Multivariate analyses were conducted to explore the impact of taste and smell disturbances on dietary intakes and cachexia-related QOL. Dietary intakes were assessed using the Ingesta-Verbal/Visual Analog Scale, while taste and smell disturbances were assessed using an 11-point Numeric Rating Scale (NRS). Cachexia-related QOL was assessed using the Functional Assessment of Anorexia/Cachexia Therapy Anorexia Cachexia Subscale (FAACT ACS). RESULTS: Overall, 378 patients provided consent to participate. After excluding patients with missing data, data were analyzed for 343 patients. Among them, 35.6% (n = 122; 95% [confidence interval (CI)] 0.28-0.38) and 20.9% (n = 72; 95% CI 0.17-0.25) experienced disturbances in taste (NRS ≥ 1) and smell (NRS ≥ 1), respectively. Multivariate analyses revealed that, independent of performance status and cancer cachexia, taste and smell disturbances were significantly associated with worse dietary intakes and deteriorating FAACT ACS scores. CONCLUSION: More severe taste and smell disturbances were associated with poorer dietary intakes and cachexia-related QOL. Diagnosing and treating such disturbances may improve dietary intakes and cachexia-related QOL, regardless of performance status and cachexia.
