Frequency of Myoclonus and its Countermeasures in Terminally Ill Patients with Cancer: A Single-Center Retrospective Study.

Myoclonus is a relatively rare involuntary movement that is often observed in palliative care settings and that can cause patient distress. The purpose of this study is to investigate the occurrence of myoclonus and countermeasures against it in terminally ill patients with cancer diagnosed by palliative care specialists at Komaki City Hospital, Japan. We retrospectively reviewed patients with terminal cancer who received palliative care consultations between January 2018 and May 2019 and who were diagnosed with myoclonus by palliative care specialists, using electronic medical records. Patient demographics, time from onset of myoclonus to death, daily opioid use, countermeasures, and outcome of myoclonus were assessed. Of 360 patients examined during this period, 45 (12.5%) were diagnosed with myoclonus. Median age was 71 (range, 43-88) years; median time from onset of myoclonus to death was 8 days (range, 0-56); opioid usage was present in 39 patients (morphine, oxycodone, and fentanyl: n = 6, 21, and 12, respectively); and median oral morphine equivalent at onset of myoclonus was 60 mg (range, 12-336 mg). Myoclonus treatment was administered to 21 patients (opioid dose reduction, opioid switching, and others: n = 14, 3, and 4, respectively). Myoclonus is a common complication in patients with terminal cancer.

Effectiveness of opioid switching for dyspnea and its predictors in cancer patients: a single-center retrospective observational study.

BACKGROUND: Morphine is the most used opioid for dyspnea, but other opioids such as oxycodone and fentanyl are increasingly used, and opioid switching to these is sometimes undertaken. No studies have verified the effectiveness of opioid switching for relief of dyspnea. We retrospectively investigated the effectiveness of opioid switching for dyspnea and its predictors. METHODS: All patients with opioid switching for dyspnea during hospitalization at Komaki City Hospital from January 2019 to August 2022 were included. Opioid switching was defined as a change to another opioid, and the assessment period for evaluating the effectiveness and adverse events of opioid switching was set as 1 week. Patients with Numeric Rating Scale or Japanese version of the Support Team Assessment Schedule reduction for dyspnea of at least 1, or with clear improvement based on medical records, were considered valid. Mitigating factors for dyspnea were identified using logistic regression analysis. RESULTS: Of the 976 patients with opioid switching, 57 patients had opioid switching for relief of dyspnea. Of these, opioid switching was effective in 21 patients (36.8%). In a multivariate analysis, older patients (odds ratio: 5.52, 95% CI: 1.50-20.20, P < 0.01), short prognosis for post-opioid switching (odds ratio: 0.20, 95% CI: 0.04-0.87, P = 0.03) and cachexia (odds ratio: 0.12, 95% CI: 0.02-0.64, P < 0.01) were significantly associated with opioid switching effects for dyspnea. There were no serious adverse events after opioid switching. CONCLUSION: This study indicates that opioid switching for dyspnea may have some effect. Furthermore, opioid switching for dyspnea may be more effective in older patients and less effective in terminally ill patients or in those with cachexia.

Effects of Antibiotics on Respiratory Symptoms in Terminally Ill Cancer Patients With Pneumonia: A Multicenter Cohort Study.

CONTEXT: Patients in the terminal stages of cancer are frequently affected by infection, especially pneumonia; but the effects of antibiotics on respiratory symptoms and factors associated with improvement are still unclear. OBJECTIVES: This study aimed to clarify the effects of antibiotics on respiratory symptoms of terminally ill cancer patients with pneumonia, and to explore factors associated with the improvement. METHODS: This was a prospective cohort study in which we consecutively recruited terminally ill cancer patients diagnosed with pneumonia and treated with antibiotics at one of 23 palliative care units across Japan. At the baseline and Day 3, primarily responsible palliative care specialists recorded patient backgrounds, the results of physical and laboratory examination, and patient symptoms using the Support Team Assessment Schedule. Improvement was defined as improvement of dyspnea, cough, and sputum production on Day 3. RESULTS: Among all 1896 patients admitted during the study periods, 137 patients (7.2%) were enrolled into this study. Improvement was achieved in 65 patients (47.4%; 95% confidence intervals, 39-56). Univariate analyses revealed that the Palliative Prognostic Index (PPI), respiratory rate (RR), and oxygen requirement were significantly associated with the improvement. A multiple logistic regression analysis identified that PPI score of ≤ 6 and RR of <20 were independently associated with the improvement (odds ratios, 4.4 [1.6-12] and 2.5 [1.1-5.5], respectively). CONCLUSION: Antibiotics may relieve respiratory symptoms from pneumonia in approximately half of the terminally ill cancer patients. PPI and respiratory rate are useful to identify the patients who received benefits of antibiotics.

Effectiveness and safety of opioids for dyspnea in patients with lung cancer: secondary analysis of multicenter prospective observational study.

Background: Patients with lung cancer are more likely to have comorbidities [e.g., interstitial lung disease (ILD)], chronic obstructive pulmonary disease) and metastases that may affect dyspnea and the effectiveness and safety of opioids for dyspnea than other cancer types. Therefore, this study examined the effectiveness and safety of opioids for dyspnea, among the patients with lung cancer. Methods: The present study is a secondary analysis of a multicenter prospective observational study examining the effectiveness and safety of opioids for dyspnea in patients with cancer in Japan. For this secondary analysis, patients with lung cancer with a documented dyspnea Numerical Rating Scale (NRS) at baseline were included. The primary outcome was dyspnea NRS, and Integrated Palliative care Outcome Scale/Support Team Assessment Schedule (IPOS/STAS) scores change between baseline and 24 hours after baseline. As secondary outcomes, we investigated the predictors of opioid effectiveness for dyspnea improvement and adverse events (nausea, somnolence, and delirium). Results: This study analyzed 124 patients with lung cancer with known dyspnea NRS at baseline. The median age was 74, and the Eastern Cooperative Oncology Group performance status of 107 patients were 3-4. Both NRS and IPOS/STAS score of dyspnea significantly improved 24 hours after opioid initiation [-1.64, 95% confidence interval (CI): -2.12 to -1.17, P<0.001; -1.03; 95% CI: -1.21 to -0.85, P<0.001; respectively]. Moreover, the improvement of NRS score was greater than the minimal clinically important difference of 1 point. In the multivariate logistic regression analysis, ILD was significantly associated with a better improvement [(hazard ratio (HR): 3.39, 95% CI: 1.34-11.09, P=0.043]. Somnolence was the most common grade 3-4 adverse event (n=16), followed by delirium (n=9). Conclusions: Opioids were effective and safe for treating dyspnea in patients with lung cancer. Furthermore, lung cancer patients with ILD may benefit more from opioids.

C-Reactive Protein and Its Relationship with Pain in Patients with Advanced Cancer Cachexia: Secondary Cross-Sectional Analysis of a Multicenter Prospective Cohort Study.

Background: Limited information is available on the relationship between C-reactive protein (CRP) levels and pain in advanced cancer. Objectives: To investigate the relationship between serum levels of CRP and subtypes of pain. Design: A secondary cross-sectional analysis of a prospective cohort study. Setting/Subjects: Patients with advanced cancer admitted to 23 palliative care units in Japan. Measurements: Patients rated the severity of pain on the numerical rating scale (NRS) and physicians evaluated pain on the integrated palliative care outcome scale (IPOS). Physicians assessed neuropathic pain and breakthrough pain based on their presence or absence. Patients were divided into four groups according to CRP levels. Comparisons were performed using the Kruskal-Wallis test or chi-squared test. To evaluate the relationship between CRP and subtypes of pain, adjusted odds ratios (ORs) and 95% confidence intervals (CIs) in logistic models were calculated. Results: We divided 1513 patients into four groups: low CRP (n = 234), moderate CRP (n = 513), high CRP (n = 352), and very high CRP (n = 414). Spearman's correlation coefficient between CRP and pain NRS and that between CRP and pain IPOS were 0.15 (p < 0.001) and 0.16 (p < 0.001), respectively. In the models of pain NRS and pain IPOS, significantly higher adjusted ORs than in the low CRP group were observed in the very high CRP group (1.81 [95% CI 1.14-2.88], p = 0.01; 1.74 [95% CI 1.18-2.57], p = 0.005, respectively). Relationships were not observed between CRP, neuropathic pain, and breakthrough pain. Conclusions: The results indicated direct relationships between CRP, pain NRS, and pain IPOS.

Efficacy of Proportional Sedation and Deep Sedation Defined by Sedation Protocols: A Multicenter, Prospective, Observational Comparative Study.

PURPOSE: To investigate the efficacy of two types of palliative sedation: proportional and deep sedation, defined by sedation protocols. METHODS: From a multicenter prospective observational study, we analyzed the data of those patients who received the continuous infusion of midazolam according to the sedation protocol. The primary endpoint was goal achievement at 4 hours: in proportional sedation, symptom relief (Integrated Palliative care Outcome Scale: IPOS ≤ 1) and absence of agitation (modified Richmond Agitation-Sedation Scale: RASS ≤ 0); in deep sedation, the achievement of deep sedation (RASS ≤ -4). Secondary endpoints included deep sedation as a result of proportional sedation, communication capacity (Communication Capacity Scale item 4 ≤ 2), IPOS and RASS scores, and adverse events. RESULTS: A total of 81 patients from 14 palliative care units were analyzed: proportional sedation (n = 64) and deep sedation (n = 17). At 4 hours, the goal was achieved in 77% (n = 49; 95% confidence interval: 66-87) with proportional sedation; and 88% (n = 15; 71-100) with deep sedation. Deep sedation was necessary in 45% of those who received proportional sedation. Communication capacity was maintained in 34% with proportional sedation and 10% with deep sedation. IPOS decreased from 3.5 to 0.9 with proportional sedation, and 3.5 to 0.4 with deep sedation; RASS decreased from +0.3 to -2.6, and +0.4 to -4.2, respectively. Fatal events related to the treatment occurred in 2% (n = 1) with proportional and none with deep sedation. CONCLUSION: Proportional sedation achieved satisfactory symptom relief while maintaining some patients' consciousness, and deep sedation achieved good symptom relief while the majority of patients lost consciousness.

Prevalence and associated factors of orphan symptoms in advanced cancer patients: a multicenter observational study.

PURPOSE: The aims of this study were to examine the prevalence of myoclonus, sweating, pruritus, hiccup, and vesical and rectal tenesmus, and to explore associated factors in patients with advanced cancer. METHODS: This multicenter prospective cohort study was conducted in 23 inpatient hospices/palliative care units in Japan from January to December 2017. The prevalence and characteristics of each symptom were assessed on admission and in the 3 days before death. We selected factors that might influence the occurrence of each symptom and investigated the association. RESULTS: A total of 1896 patients were enrolled. The prevalence of orphan symptoms rose from admission to the 3 days before death: myoclonus 1.3 to 5.3% (95% CI 0.9-1.9%/4.3-6.5%), sweating 1.8 to 4.1% (95% CI 1.3-2.6%/3.1-5.1%), hiccup 1.1 to 1.8% (95% CI 0.7-1.7%/1.2-2.6%), and tenesmus 0.7 to 0.9% (0.4-1.2%/0.5-1.5%). Prevalence of pruritus fell from 3.5 to 2.5% (95% CI 2.7-4.4%/1.8-3.4%). Sweating, pruritus, and hiccups persisted throughout the day in nearly half of the patients. Myoclonus was significantly associated with brain tumors, sweating with opioids and antipsychotics, pruritus with liver and biliary tract cancer, cholestasis and severe diabetes, hiccup with male gender, digestive tract obstruction, severe diabetes, and renal failure. Vesical tenesmus was associated with urinary cancer, antipsychotics, and anticholinergics and rectal tenesmus with pelvic cavity cancer. CONCLUSION: We found that orphan symptoms occurred in 0.5-5.0% of patients, increased over time except for pruritus, and persisted in half of the patients.

Patient-perceived symptomatic benefits of olanzapine treatment for nausea and vomiting in patients with advanced cancer who received palliative care through consultation teams: a multicenter prospective observational study.

PURPOSE: To examine the safety, effectiveness, and patient-perceived benefit of treatment with olanzapine for nausea and vomiting (N/V) in patients with advanced cancer. METHODS: We conducted a multicenter prospective observational study in a tertiary care setting (Trial registration number: UMIN000020493, date of registration: 2016/1/12). We measured the following: average nausea in the last 24 h using a Numeric Rating Scale (NRS: range 0-10) at baseline and day 2, patient-perceived treatment benefit (based on a 5-point verbal scale), and adverse events (AEs; using the Common Terminology Criteria for Adverse Events version 4). RESULTS: The 85 participants (45% men) had a mean age of 58.7±15.8 years. Major causes of N/V were opioids (44%) and chemotherapy (34%). All patients received a daily dose of olanzapine of 5 mg or less as first-line treatment (N=35) or second- or later-line treatment (N=50). Nausea NRS decreased from 6.1±2.2 to 1.8±2.0 (differences: -4.3, 95% CI -3.7 to -4.9, p<0.001). The proportion of patients who did not experience vomiting episodes in the last 24 h increased from 40-89%. Mean decrease in nausea NRS by patient-perceived treatment benefit were as follows: -0.8 for "none" (n=4, 5%); -2.8 for "slight" (n=17, 20%); -3.3 for "moderate" (n=14, 16%); -4.7 for "lots" (n=25, 29%); and -6.1 for "complete" (n=25, 29%; p-for-trend<0.001). The most prevalent AE was somnolence (n=15, 18%). CONCLUSION: Short-term and relatively low-dose olanzapine treatment was effective for multifactorial N/V. Confirmatory studies with longer observation periods are needed to clarify the duration of the effect and adverse events.

Differences among institutions in the prevalence of and indications for urinary catheterization of advanced cancer patients at palliative care units: A multicenter prospective cohort study (EASED).

BACKGROUND: Studies on the appropriate use of urinary catheters for cancer patients at the end of life are limited. AIM: To clarify the differences among institutions in the prevalence of and indications for urinary catheterization of advanced cancer patients at palliative care units. DESIGN: Pre-planned secondary analysis of a multicenter, prospective cohort study; East-Asian collaborative cross-cultural Study to Elucidate the Dying process (EASED). SETTING/PARTICIPANTS: This study enrolled consecutive advanced cancer patients admitted to palliative care units between January and December 2017. The final study group comprised 1212 patients from 21 institutions throughout Japan. RESULTS: Out of the 1212 patients, 380 (31.4%; 95% confidence interval, 28.7%-34.0%) underwent urinary catheterization during their palliative care unit stay, and the prevalence of urinary catheterization in patients who died at palliative care units by institution ranged from 0.0% to 55.4%. When the 21 participating institutions were equally divided into three groups according to the institutional prevalence of catheterization, patients with difficulty in moving safely, exhaustion on movement, and restlessness or agitation were more likely to be catheterized in institutions with a high prevalence of catheterization than in those with a low or moderate prevalence (p < 0.008, p = 0.008, and p < 0.008, respectively). CONCLUSION: This study revealed that the institutional prevalence of urinary catheterization in advanced cancer patients at palliative care units widely varied. Further studies are needed to establish the appropriate use of urinary catheters, especially in patients with difficulty in moving safely, exhaustion on movement, and restlessness or agitation.

How successful are we in relieving terminal dyspnea in cancer patients? A real-world multicenter prospective observational study.

PURPOSE: Parenteral morphine is widely used for dyspnea of imminently dying cancer patients, but the outcomes to expect over time remain largely unknown. We examined outcomes after the administration of parenteral morphine infusion over 48 h in cancer patients with a poor performance status. METHODS: This was a multicenter prospective observational study. Inclusion criteria were metastatic/locally advanced cancer, ECOG performance status = 3-4, a dyspnea intensity ≥ 2 on a Support Team Assessment Schedule, Japanese version (STAS-J), and receiving specialized palliative care. After initiating parenteral morphine infusion, we measured dyspnea STAS-J as well as Memorial Delirium Assessment Scale (MDAS), item 9, and Communication Capacity Scale (CCS), item 4, every 6 h over 48 h. RESULTS: We enrolled 167 patients (median survival = 4 days). The mean age was 70 years, 80 patients (48%) had lung cancer, and 109 (65%) had lung metastases. The mean STAS-J scores decreased from 3.1 (95% confidence interval (CI) = 3.0-3.2) at the baseline to 2.1 (95%CI = 1.9-2.2) at 6 h, and remained 1.6-1.8 over 12-48 h. The proportion of patients with dyspnea relief (STAS-J ≤ 1) increased to 39% at 6 h, and ranged between 49 and 61% over 12-48 h. In contrast, up to 6.6 and 20% of patients showed hyperactive delirium (MDAS item 9 ≥ 2) and an inability to communicate (CCS item 4 = 3), respectively, over 48 h. CONCLUSIONS: Overall, terminal dyspnea was relatively well controlled with parenteral morphine, though a significant number of patients continued to suffer from dyspnea. Future efforts are needed to improve outcomes following standardized dyspnea treatment using patient-reported outcomes for imminently dying patients.

A Multicenter Cohort Study to Explore Differentiating Factors between Tumor Fever and Infection among Advanced Cancer Patients.

Background: Tumor fever and infection are common febrile etiologies among advanced cancer patients. To date, only few studies have been conducted to differentiate between tumor fever and infections. Objective: This study aimed to identify discriminating factors that provide rapid results and are feasible and minimally invasive for discriminating between tumor fever and infection in advanced cancer patients. Methods: This is a retrospective cohort study. Advanced cancer patients with clinically diagnosed tumor fever or infection, who received medical treatment from palliative care specialists in 10 nationwide Japanese hospitals, were consecutively identified during August 2012 and November 2014. The symptoms, physical findings, blood test results at baseline and during fever, imaging findings, and sociodemographic factors of these patients were retrospectively extracted. Results: Thirty-three patients with tumor fever and 72 patients with infection were identified. Their mean age was 68.8 years, 68 (64.8%) were men, and the median palliative performance status (PPS) was 50. Statistically significant factors predicting tumor fever by logistic regression analysis were as follows: deterioration of PPS (odds ratio, 0.078), shaking chills during fever (0.067), and change from baseline data of neutrophil/lymphocyte ratio of ≥5 (0.14). Conclusions: Shaking chills during fever, and changes from baseline of performance status and white blood cell differentiation can be useful to differentiate between tumor fever and infection among advanced cancer patients. Further confirmatory studies are needed.

Effect of continuous intravenous oxycodone infusion in opioid-naïve cancer patients with dyspnea.

AIM: Dyspnea is among symptoms that decrease quality of life for terminal cancer patients. There are few reports of the positive effects of oxycodone for the treatment of dyspnea, and no studies have focused on opioid-naïve patients. This study aimed to determine the efficacy and safety of continuous intravenous oxycodone infusion for opioid-naïve cancer patients with dyspnea. METHODS: Eligible patients were opioid-naïve cancer inpatients who received continuous oxycodone infusion as a treatment for dyspnea under the care of the palliative care team at Komaki City Hospital between November 2013 and December 2016. We retrospectively investigated the improvement of dyspnea following continuous oxycodone infusion from the medical records. RESULTS: This study included 19 patients, and the response rate to oxycodone infusion for dyspnea was 68.4%. Most participants were terminal cancer patients with performance status 3 or 4. Median survival of participants following continuous oxycodone infusion was 6 (range 1-377) days. No serious adverse events such as respiratory depression or somnolence were noted. CONCLUSION: Continuous oxycodone infusion could be a reasonable treatment option in the management of dyspnea in opioid-naïve cancer patients.

Families' Sense of Abandonment When Patients Are Referred to Hospice.

BACKGROUND: Terminally ill patients with cancer and their families may have a sense of abandonment when they are referred to hospice. This study aimed to clarify the prevalence of families' sense of abandonment, explore the association between the sense of abandonment and the oncologists' behaviors, and investigate the association between the sense of abandonment and the families' depression and complicated grief. PATIENTS AND METHODS: This was part of a nationwide self-reported questionnaire survey of bereaved families of patients with cancer who died in inpatient hospices. We sent questionnaires to 947 bereaved families of patients with cancer who died in 133 certified hospices between May 2012 and January 2014. RESULTS: Among 707 responses obtained, a total of 189 (26.7%) families felt abandoned. The factors significantly associated with a greater sense of abandonment were that the oncologists said there was nothing more to do for the patient, the patient's age of less than 60 years, and being the patient's spouse. The factors significantly associated with a lower sense of abandonment were that the oncologists reassured the patients that they had received the best anticancer treatment, that the oncologists recommended hospices as one potential choice rather than mandatory, and that a palliative care team provided care. Families with a sense of abandonment had higher scores on the Patient Health Questionnaire-9 (p = .096) and Brief Grief Questionnaire (p < .001). CONCLUSION: Approximately a quarter of bereaved families had a sense of abandonment, which was associated with a higher rate of complicated grief. Oncologists may reduce the sense of abandonment by reassuring that the patients received the best anticancer treatment, recommending hospices as a potential choice rather than as mandatory, and by not saying there is nothing that can be done for the patients. IMPLICATIONS FOR PRACTICE: This self-reported questionnaire study investigated the prevalence of families' feelings of abandonment when they were referred to hospice care, focusing on the association of sense of abandonment and the behavior of their physicians. Nearly a quarter of families felt abandoned by the referral to hospice, and the behavior of some oncologists was associated with the sense of abandonment.

Incidence of Acute Suppurative Sialadenitis in End-Stage Cancer Patients: A Retrospective Observational Study.

CONTEXT: Acute suppurative sialadenitis (hereafter referred to as sialadenitis) is accompanied by pain and fever and can diminish the quality of life in end-stage cancer patients; however, its incidence is not clear. OBJECTIVES: We conducted this study to elucidate the incidence of sialadenitis in end-stage cancer patients. METHODS: Retrospective review and observational study based on patients' medical records. SUBJECTS: About 726 consecutive cancer patients who died on the palliative care unit of our hospital between April 2012 and November 2016 were included. MEASUREMENTS: Median duration between sialadenitis onset and death, concomitant treatment, average infusion volume per day, site of onset, symptoms, effectiveness of antibiotic treatment, and mean duration until symptomatic relief. RESULTS: The incidence of sialadenitis was 2.9% (21 of 726 cases). The median duration from onset to death was 20 days (range 2-112); concomitant treatment included opioids in 11 patients (55%), anticholinergic drugs in six patients (28%), steroids in three patients (14%), and oxygen inhalation in five patients (23%); average infusion volume per day was 588 ± 307 mL; site of onset was submandibular gland in 12 patients (57%) and parotid gland in nine patients (42%); and symptoms were pain in 18 patients (85%) and fever in 13 patients (61%). Antibiotic treatment was administered in 18 patients (85%), and the mean duration until symptomatic relief was 4.0 ± 1.5 days. CONCLUSION: Sialadenitis is a rare complication in end-stage cancer patients; however, it is important to recognize that it can be associated with severe symptoms, including fever and pain.

Predictors of Delirium in Corticosteroid-Treated Patients with Advanced Cancer: An Exploratory, Multicenter, Prospective, Observational Study.

BACKGROUND: Corticosteroids are often used to treat fatigue and anorexia, but occasionally produce delirium. Information on the predictors of delirium in corticosteroid-treated cancer patients remains limited. OBJECTIVE: To identify potential factors predicting the development of delirium in corticosteroid-treated cancer patients. DESIGN: An exploratory, multicenter, prospective, observational study. SETTING/SUBJECTS: Inclusion criteria for this study were patients who had metastatic or locally advanced cancer and a fatigue or anorexia intensity score of 4 or more on a 0-10 Numerical Rating Scale. MEASUREMENT: Univariate and multivariable analyses were performed to identify the predictors of delirium diagnosed by the Confusion Assessment Method (CAM) within three days of initiation of corticosteroids. RESULTS: Among 207 patients administered corticosteroids, 35 (17%; 95% confidence interval [CI] 12%-23%) developed at least one episode of delirium diagnosed by the CAM. Factors predictive of the development of delirium were as follows: Palliative Performance Scale ≤20, Eastern Cooperative Oncology Group Performance Status (ECOG PS) = 4, the Support Team Assessment Schedule (STAS) score of drowsiness >1, concurrent opioid use, parenteral hydration volume ≤500 mL, and the absence of lung metastasis. A multivariable analysis identified the independent factors predicting responses as ECOG PS = 4 (odds ratio [OR] 4.0; 95% CI 1.7-9.3), STAS score of drowsiness >1 (OR 3.4; 95% CI 1.4-8.2), and concurrent opioid use (OR 3.7; 95% CI 1.0-13). CONCLUSION: Delirium in corticosteroid-treated advanced cancer patients may be predicted by PS, drowsiness, and concurrent opioid use. Larger prospective studies are needed to confirm these results.

Predictors of responses to corticosteroids for anorexia in advanced cancer patients: a multicenter prospective observational study.

PURPOSE: Although corticosteroids are widely used to relieve anorexia, information regarding the factors predicting responses to corticosteroids remains limited. The purpose of the study is to identify potential factors predicting responses to corticosteroids for anorexia in advanced cancer patients. METHODS: Inclusion criteria for this multicenter prospective observational study were patients who had metastatic or locally advanced cancer and had an anorexia intensity score of 4 or more on a 0-10 Numerical Rating Scale (NRS). Univariate and multivariate analyses were conducted to identify the factors predicting ≥2-point reduction in NRS on day 3. RESULTS: Among 180 patients who received corticosteroids, 99 (55 %; 95 % confidence interval [CI], 47-62 %) had a response with ≥2-point reduction. Factors that significantly predicted responses were Palliative Performance Scale (PPS) > 40 and absence of drowsiness. In addition, factors that tended to be associated with ≥2-point reduction in NRS included PS 0-3, absence of diabetes mellitus, absence of peripheral edema, presence of lung metastasis, absence of peritoneal metastasis, baseline anorexia NRS of >6, presence of pain, and presence of constipation. A multivariate analysis showed that the independent factors predicting responses were PPS of >40 (odds ratio = 2.7 [95 % CI = 1.4-5.2]), absence of drowsiness (2.6 [1.3-5.0]), and baseline NRS of >6 (2.4 [1.1-4.8]). CONCLUSIONS: Treatment responses to corticosteroids for anorexia may be predicted by PPS, drowsiness, and baseline symptom intensity. Larger prospective studies are needed to confirm these results.

Predictors of response to corticosteroids for dyspnea in advanced cancer patients: a preliminary multicenter prospective observational study.

PURPOSE: Although corticosteroids can relieve dyspnea in advanced cancer patients, factors predicting the response remain unknown. We aimed to explore potential factors predicting the response to corticosteroids for dyspnea in advanced cancer patients. METHODS: In this preliminary multicenter prospective observational study, we included patients who had metastatic or locally advanced cancer, were receiving specialized palliative care services, and had a dyspnea intensity of ≥3 on a 0-10 Numerical Rating Scale (NRS) (worst during the last 24 h). The primary endpoint was NRS of dyspnea on day 3 after the administration of corticosteroids. Univariate/multivariate analyses were conducted to identify factors predicting ≥1-point reduction in NRS. RESULTS: Of 74 patients who received corticosteroids, 50 (68%) showed ≥1-point reduction in dyspnea NRS. Factors that significantly predicted the response were an age of 70 years or older (82 vs. 53%, p = 0.008), absence of liver metastases (77 vs. 46%, p = 0.001), Palliative Prognostic Index (PPI) ≤ 6 (90 vs. 61%, p = 0.041), presence of pleuritis carcinomatosa with a small collection of pleural effusions (84 vs. 55%, p = 0.011), presence of audible wheezes (94 vs. 60%, p = 0.014), and baseline dyspnea NRS ≥7 (76% vs. 52%, p = 0.041). In a multivariate analysis, factors predicting response included PPI <6 (odds ratio (OR), 36.2; p = 0.021), baseline dyspnea NRS (worst) ≥7 (OR, 6.6; p = 0.036), and absence of liver metastases (OR, 0.19; p = 0.029) or ascites/liver enlargement (OR, 0.13; p = 0.050). CONCLUSIONS: The patient characteristics, etiologies of dyspnea, and clinical manifestations may predict responses to corticosteroids for dyspnea. Larger prospective studies are promising to confirm our findings.

Predictors of Responses to Corticosteroids for Cancer-Related Fatigue in Advanced Cancer Patients: A Multicenter, Prospective, Observational Study.

CONTEXT: Although corticosteroids are widely used to relieve cancer-related fatigue (CRF), information regarding the factors predicting responses to corticosteroids remains limited. OBJECTIVES: The aim of this study was to identify potential factors predicting responses to corticosteroids for CRF in advanced cancer patients. METHODS: Inclusion criteria for this multicenter, prospective, observational study were patients who had metastatic or locally advanced cancer and had a fatigue intensity score of 4 or more on a 0-10 Numerical Rating Scale (NRS). Univariate and multivariate analyses were conducted to identify the factors predicting two-point reduction or more in NRS on day 3. RESULTS: Among 179 patients who received corticosteroids, 86 (48%; 95% CI 41%-56%) had a response with two-point reduction or more. Factors that significantly predicted responses were performance status score of 3 or more, Palliative Performance Scale score more than 40, absence of ascites, absence of drowsiness, absence of depression, serum albumin level greater than 3 mg/dL, serum sodium level greater than 135 mEq/L, and baseline NRS score greater than 5. A multivariate analysis showed that the independent factors predicting responses were baseline NRS score greater than 5 (odds ratio [OR] 6.6, 95% CI 2.8-15.4), Palliative Performance Scale score more than 40 (OR 4.4, 95% CI 2.1-9.3), absence of drowsiness (OR 3.4, 95% CI 1.7-6.9), absence of ascites (OR 2.3, 95% CI 1.1-4.7), and absence of pleural effusion (OR 2.2, 95% CI 1.0-5.0). CONCLUSION: Treatment responses to corticosteroids for CRF may be predicted by baseline symptom intensity, performance status, drowsiness, and severity of fluid retention symptoms. Larger prospective studies are needed to confirm these results.

Convenient measurement of systolic pressure: the reliability and validity of manual radial pulse pressure measurement.

BACKGROUND: It is important to assess a patient's medical condition noninvasively, particularly in hospice care settings. OBJECTIVE: The aim of this study was to investigate the reliability of manually measuring the radial pulse pressure and its validity for predicting the systolic blood pressure. DESIGN: An observational study consisting of two phases: a reliability study and a validity study. SETTING/SUBJECTS: Patients admitted to a palliative care unit. MEASUREMENTS: To assess the interrater reliability, the radial pulse pressure was prospectively measured independently by a physician and nurse using a three-level assessment (impalpable, weak, and normal) in 43 patients admitted to a palliative care unit. To assess the validity, we analyzed a total of 156 patients, consisting of the prospectively collected patients and 113 patients retrospectively recruited. Radial pulse and systolic blood pressures were recorded on admission. We calculated the sensitivity and specificity of the radial pulse pressure to predict a systolic blood pressure of 90 mm Hg or more. RESULTS: The κ coefficient of the physician and nurse was 0.788. The sensitivity and specificity to predict a systolic blood pressure of 90 mm Hg or more using the cutoff point of a normal versus weak/impalpable radial pulse pressure were 84% (95% confidence intervals, 77-89) and 82% (52-96), respectively. CONCLUSIONS: Manually measuring the radial pulse pressure is reliable and can be used to indicate a systolic blood pressure of 90 mm Hg or more.
