Acupuncture for Cancer-Related Anorexia: a Review of the Current Evidence.

PURPOSE OF REVIEW: Loss of appetite/anorexia is extremely common among cancer patients, affecting as many as half of newly diagnosed patients and 70% of patients with advanced disease. Effective management of this disabling symptom of cancer remains a major challenge in the field of oncology. We conducted a systematic review of the current evidence on acupuncture and/or moxibustion as an intervention for cancer-related anorexia. RECENT FINDINGS: Acupuncture, as a part of traditional Chinese medicine practice, has demonstrated effectiveness in managing many cancer- and treatment-related symptoms, especially chemotherapy-induced or postoperative nausea. However, the efficacy of acupuncture in treating cancer-related anorexia/loss of appetite is not clear. The current level of evidence is insufficient to make a definitive conclusion on the benefit of acupuncture/moxibustion for treating chronic cancer-related anorexia/appetite problems. Future large randomized controlled trials of high methodological quality are needed.

Random urine drug testing among patients receiving opioid therapy for cancer pain.

BACKGROUND: There is limited information regarding the true frequency of nonmedical opioid use (NMOU) among patients receiving opioid therapy for cancer pain. Data to guide patient selection for urine drug testing (UDT) as well as the timing and frequency of ordering UDT are insufficient. This study examined the frequency of abnormal UDT among patients with cancer who underwent random UDT and their characteristics. METHODS: Demographic and clinical information for patients with cancer who underwent random UDT were retrospectively reviewed and compared with a historical cohort that underwent targeted UDT. Random UDT was ordered regardless of a patient's risk potential for NMOU. Targeted UDT was ordered on the basis of a physician's estimation of a patient's risk for NMOU. RESULTS: In all, 552 of 573 eligible patients (96%) underwent random UDT. Among these patients, 130 (24%) had 1 or more abnormal results; 38 of the 88 patients (43%) who underwent targeted UDT had 1 or more abnormal results. When marijuana was excluded, 15% of the random group and 37% of the targeted group had abnormal UDT findings (P < .001). It took a shorter time from the initial consultation to detect 1 or more abnormalities with the random test than the targeted test (median, 130 vs 274 days; P = .02). Abnormal random UDT was independently associated with younger age (P < .0001), male sex (P = .03), Cut Down, Annoyed, Guilty, and Eye Opener-Adapted to Include Drugs positivity (P = .001), and higher Edmonton Symptom Assessment System anxiety (P = .01). CONCLUSIONS: Approximately 1 in 4 patients receiving opioids for cancer pain at a supportive care clinic who underwent random UDT had 1 or more abnormalities. Random UDT detected abnormalities earlier than the targeted test. These findings suggest that random UDT is justified among patients with cancer pain.

Implications of the Parenteral Opioid Shortage for Prescription Patterns and Pain Control Among Hospitalized Patients With Cancer Referred to Palliative Care.

IMPORTANCE: The recent parenteral opioid shortage (POS) has potential implications for cancer-related pain management in hospitalized patients. OBJECTIVE: This study compared changes in opioid prescriptions and clinically improved pain (CIP) among patients treated by an inpatient palliative care (PC) team before and after our institution first reported the POS. DESIGN, SETTING, AND PARTICIPANTS: A cohort study of 386 eligible patients with cancer treated at a comprehensive cancer center 1 month before and after the announcement of the POS. We reviewed data from electronic health records, including patient demographics, opioid type, route of administration, and dose. Board-certified palliative care specialists assessed CIP at follow-up day 1. EXPOSURES: The announcement of the POS by the institution's pharmacy and therapeutics committee on February 8, 2018. MAIN OUTCOMES AND MEASURES: The primary outcome was to measure the change in opioid prescription patterns of physicians, and the secondary outcome was to measure the proportion of patients who achieved CIP before and after announcement of the POS. RESULTS: Of 386 eligible patients, 196 were men (51%), 270 were white (70%), and the median age was 58 years (interquartile range, 46-67 years). Parenteral opioids were prescribed less frequently by the referring oncology teams after the POS (56 of 314 [18%]) vs before the POS (109 of 311 [35%]) (P < .001). The PC team also prescribed fewer parenteral opioids after the POS (96 of 336 [29%]) vs before the POS (159 of 338 [47%]) (P < .001). After the POS (vs before the POS), significantly fewer patients achieved CIP on follow-up day 1 (119 [62%] vs 144 [75%] of 193; P = .01). Multivariate analysis showed that before the POS, patients had an 89% higher chance of achieving CIP on follow-up day 1 (odds ratio, 1.89; 95% CI, 1.22-2.94; P = .005). CONCLUSIONS AND RELEVANCE: There was a significant change in opioid prescription patterns associated with the POS. Furthermore, after the POS, fewer patients achieved CIP. These factors have potential implications for patient satisfaction and hospital length of stay.

A prospective study of family conferences: effects of patient presence on emotional expression and end-of-life discussions.

CONTEXT: Limited research has taken place examining family conferences (FCs) with patients with advanced cancer and their caregivers in the palliative care setting. OBJECTIVES: To characterize the FCs involving cancer patients in a palliative care unit at a comprehensive cancer center and examine the effects of patient participation on emotional expression by the participants and end-of-life discussions. METHODS: A data collection sheet was completed immediately after 140 consecutive FCs that documented the number of participants, caregiver demographics, expressions of emotional distress, dissatisfaction with care, and the topics discussed. Patient demographics and discharge disposition also were collected. RESULTS: Seventy (50%) patients were female, 64 (46%) were white, and 127 (91%) had solid tumors. Median age of patients was 59 years. Patients participated in 68 of 140 FCs (49%). Primary caregivers (n = 140) were female (66%), white (49%), and the spouse/partner (59%). Patients verbalized distress frequently (73%). Primary caregivers' verbal expression of emotional distress was high (82%) but not significantly affected by patient presence (82% vs. 82%, P = 0.936). Verbal expressions of emotional distress by other family members were more common when patients were absent (87%) than when present (73%), P = 0.037. Questions concerning advance directives (21%), symptoms anticipated at death (31%), and caregiver well-being (29%) were infrequent. Patient presence was significantly associated with increased discussions regarding goals of care (P = 0.009) and decreased communication concerning prognosis (P = 0.004) and what symptoms dying patients may experience (P < 0.001). CONCLUSION: There was a high frequency of expression of emotional distress by patients and family members in FCs. Patient participation was significantly associated with decreased verbal emotional expression by family members but not the primary caregiver and was associated with fewer discussions regarding prognosis and what dying patients may experience.

Effects of melatonin on appetite and other symptoms in patients with advanced cancer and cachexia: a double-blind placebo-controlled trial.

PURPOSE: Prior studies have suggested that melatonin, a frequently used integrative medicine, can attenuate weight loss, anorexia, and fatigue in patients with cancer. These studies were limited by a lack of blinding and absence of placebo controls. The primary purpose of this study was to compare melatonin with placebo for appetite improvement in patients with cancer cachexia. PATIENTS AND METHODS: We performed a randomized, double-blind, 28-day trial of melatonin 20 mg versus placebo in patients with advanced lung or GI cancer, appetite scores ≥ 4 on a 0 to 10 scale (10 = worst appetite), and history of weight loss ≥ 5%. Assessments included weight, symptoms by the Edmonton Symptom Assessment Scale, and quality of life by the Functional Assessment of Anorexia/Cachexia Therapy (FAACT) questionnaire. Differences between groups from baseline to day 28 were analyzed using one-sided, two-sample t tests or Wilcoxon two-sample tests. Interim analysis halfway through the trial had a Lan-DeMets monitoring boundary with an O'Brien-Fleming stopping rule. Decision boundaries were to accept the null hypothesis of futility if the test statistic z < 0.39 (P ≥ .348) and reject the null hypothesis if z > 2.54 (P ≤ .0056). RESULTS: After interim analysis of 48 patients, the study was closed for futility. There were no significant differences between groups for appetite (P = .78) or other symptoms, weight (P = .17), FAACT score (P = .95), toxicity, or survival from baseline to day 28. CONCLUSION: In cachectic patients with advanced cancer, oral melatonin 20 mg at night did not improve appetite, weight, or quality of life compared with placebo.

Growth of an academic palliative medicine program: patient encounters and clinical burden.

CONTEXT: Information regarding the challenges of clinical growth and staffing of palliative care programs is limited. OBJECTIVES: Our aim was to describe the growth and staffing structure of a palliative care program at a comprehensive cancer center. METHODS: During fiscal years ending in 2000 through 2010, we recorded all billed palliative care consultations and follow-ups. To determine the yearly clinical burden per physician, advanced practice nurse (APN), and physician assistant (PA), we calculated the mean number of patient encounters per clinical full-time equivalents. Increase in absolute number of patient encounters and relative (%) growth from year to year were calculated. RESULTS: Over the 10-year history of the program, the number of outpatient consultations tripled, whereas the inpatient consultations increased from 73 to 1880. In all cases, with the exception of the first year of operation, the vast majority of clinical activity was in the inpatient hospital setting. Growth in the ratio of inpatient consultations per operational hospital beds was noted during the first five years of the program followed by a more modest increase in the succeeding five years. In fiscal year 2010, palliative care physicians had 6.2 patient encounters per working day, and APNs/PAs independently evaluated and treated 4.0 additional patients. CONCLUSION: Over the 10-year history, there has been an increase in the number of patient consultations seen by our palliative care program. The clinical burden was manageable during the first three years but quickly became too burdensome. Active recruitment of new faculty was required to sustain the increased clinical activity.

Preliminary report: vitamin D deficiency in advanced cancer patients with symptoms of fatigue or anorexia.

BACKGROUND: Vitamin D deficiency in noncancer patients is associated with symptoms of fatigue, muscle weakness, and depression. These symptoms are common among advanced cancer patients. We investigated the prevalence of low serum vitamin D levels in cancer patients with fatigue or poor appetite and their association with symptom burden and other correctable endocrine abnormalities. METHODS: This was a retrospective review of 100 consecutive cancer patients with appetite or fatigue scores of ≥4 of 10 referred to a supportive care clinic. We investigated serum levels of 25(OH) vitamin D, cortisol, thyroid-stimulating hormone, and bioavailable testosterone. Symptoms were measured by the Edmonton Symptom Assessment Scale. Serum 25(OH) vitamin D <20 ng/mL was considered deficient; ≥20 ng/mL and <30 ng/mL were considered insufficient. RESULTS: Patients were predominantly male (68%) and white (66%), with a median age of 60 years (range, 27-91 years). Gastrointestinal (30%) and lung (22%) cancers were predominant. Forty-seven patients (47%) were vitamin D deficient and 70 (70%) were insufficient. Thirteen of 70 patients (19%) with vitamin D insufficiency were on supplementation. Vitamin D deficiency was more common among nonwhites (82% versus 36%) and females. No significant association was found between vitamin D and symptoms. Hypogonadic males had a significantly lower mean 25(OH) vitamin D level than eugonadic males. CONCLUSIONS: Low vitamin D levels were highly prevalent among advanced cancer patients with cachexia or fatigue. Vitamin D deficiency was more frequent among nonwhite and female patients. Vitamin D levels were also significantly lower in male patients with hypogonadism.

Associations among hypogonadism, C-reactive protein, symptom burden, and survival in male cancer patients with cachexia: a preliminary report.

CONTEXT: Cachexia is characterized by muscle wasting, anorexia, and elevated inflammatory markers. In patients without cancer, hypogonadism is associated with lower lean body mass, increased symptom burden, and decreased survival. Hypogonadism in cancer cachexia could exacerbate symptoms, facilitate a proinflammatory state, and decrease survival. OBJECTIVES: To explore the relationships among these factors, a retrospective study of male cancer patients was conducted. METHODS: The charts of 98 consecutive male patients referred to a cachexia clinic at a comprehensive cancer center were reviewed. All patients reported weight loss of >5% within the preceding six months; the median age was 60 years. Fifty-seven (58%) had serum C-reactive protein (CRP), and 68 (69%) had total testosterone evaluated. Symptoms were evaluated by the Edmonton Symptom Assessment Scale. RESULTS: Median CRP was 20mg/L, and median testosterone level was 185 ng/dL (6.42 nmol/L) (normal > or = 240 ng/dL or 8.36 nmol/L). There was an inverse correlation between testosterone and CRP levels (P<0.01). Lower testosterone was associated with increased dyspnea and insomnia (P<0.05). Poor appetite and insomnia (P<0.05) correlated with elevated CRP. Survival of patients with testosterone levels < or = 185 ng/dL (6.42 nmol/L) was decreased compared with that of those with levels >185 ng/dL (13 vs. 62 weeks, P=0.004). Patients with CRP levels >10mg/L had decreased survival compared with those with levels < or = 10mg/L (15 vs. 46 weeks, P=0.01). The combination of hypogonadism and elevated CRP was associated with poorer prognosis. Elevated CRP levels were associated with increased symptom burden and decreased survival. Low testosterone was associated with decreased survival and correlated inversely with CRP levels, dyspnea, and insomnia. CONCLUSION: Our preliminary results suggest that testosterone and CRP may be additive or synergistic as markers for survival in male patients and could be useful in future prognostic models.

Characteristics of family conferences in a palliative care unit at a comprehensive cancer center.

PURPOSE: Family conferences are used to facilitate communication concerning end-of-life issues with patients and their families. The purpose of our study was to obtain preliminary information on the characteristics of family conferences that take place in an inpatient palliative care unit (PCU). METHODS: A retrospective chart review was conducted during a 6-month period that identified 123 documented family conferences. Data including demographic information, type of cancer, and discharge disposition were collected. Timing, number of participants, expressions of emotional distress, conflict with health care providers, and topics discussed during the conference were collected. RESULTS: Sixty-one patients (50%) were female, 75 (61%) were white, 95 (77%) had solid tumors. Median age of patients was 61. In 74 of the 123 documented family meetings (60%), patients actively participated. Family conferences took place a median of 3 days prior to discharge. During the meetings, questions concerning advanced directives and withdrawal of care were found to be infrequent. Eighteen percent of patients expressed emotional distress, while 40% of families expressed distress which was higher at 47% when the patient was not present. CONCLUSIONS: Family conferences involved a high degree of patient participation and occurred at the end of a patients stay in our PCU. A trend toward greater expression of emotional distress displayed by family members was found when patients did not participate in the meetings. Further prospective studies that use validated tools to assess the content of the meetings and their impact on alleviating distress in patients and their family are needed.
