RESUMO

OBJECTIVE: Though randomized controlled trials have demonstrated relatively comparable clinical outcomes with triple therapy (methotrexate [MTX], sulfasalazine [SSZ], and hydroxychloroquine [HCQ]) compared to combination therapy (tumor necrosis factor inhibitor [TNFi] and MTX), real-world experiences comparing these strategies have not been well studied. METHODS: We evaluated the clinical effectiveness and effects of medication discontinuation of triple therapy with MTX/SSZ/HCQ versus combination therapy with TNFi/MTX in rheumatoid arthritis (RA) patients enrolled in the Corrona RA Drug Safety & Effectiveness Registry. Propensity score matching was used to match patients up to a ratio of 1:3 to adjust for imbalances between treatment groups, with stratification performed according to biologics-naive or biologics-exposed status of study participants. RESULTS: Patients eligible for analysis in this study included biologics-naive RA patients (3,926 who received combination therapy with TNFi/MTX and 262 who received triple therapy with MTX/SSZ/HCQ) and biologics-exposed RA patients (3,365 who received combination therapy with TNFi/MTX and 130 patients who received triple therapy with MTX/SSZ/HCQ). Before propensity score matching, numerous factors were imbalanced between the treatment groups, with triple therapy patients generally being older, having a longer disease duration of RA and lower RA disease activity, and more likely having a history of malignancy and other comorbidities. After matching, almost all (93-98%) triple therapy patients could be matched to TNFi/MTX therapy patients, and cohort characteristics were generally well balanced. Discontinuation of medication was greater in triple therapy patients referent to TNFi/MTX therapy patients (adjusted hazard ratio [HR] of 2.17 [95% confidence interval 1.63-2.88] in the biologics-naive group; adjusted HR of 1.51 [95% confidence interval 1.06-2.15] in the biologics-exposed group). At 6 months, the proportion of biologics-naive patients attaining low disease activity was significantly greater in the TNFi/MTX treatment group (49.2% in TNFi/MTX therapy patients versus 33.3% in triple therapy patients), as was the mean change in Clinical Disease Activity Index scores (-9.3 units versus -5.5 [95% confidence interval -1.5, -6.1]). Corresponding results in the biologics-exposed patients numerically favored TNFi/MTX therapy compared to triple therapy but did not reach statistical significance. CONCLUSION: Few patients receive triple therapy with MTX/SSZ/HCQ in the US. In the present study, drug persistence and clinical effectiveness outcomes were less favorable in triple therapy patients compared to TNFi/MTX therapy patients.

RESUMO

OBJECTIVE: To examine predictors of remission among patients with psoriatic arthritis (PsA) initiating a tumor necrosis factor (TNF) inhibitor. METHODS: Patients with PsA enrolled in the Corrona Registry between 2005 and 2013 were followed from initiation of a TNF inhibitor (TNFi; etanercept, adalimumab, infliximab, certolizumab, or golimumab) to the visit closest to 12 months. Additional inclusion criteria included 3 tender or 3 swollen joints. Outcomes of interest were Clinical Disease Activity Index (CDAI) ≤ 2.8 (remission), low disease activity (LDA; CDAI ≤ 10), change in the modified Health Assessment Questionnaire (mHAQ) ≥ 0.35 and achievement of mHAQ < 0.30. Predictors were measured on or before TNFi initiation. Covariates significant in univariable logistic regression models and ≤ 5% missing values were included in a multivariable model and removed individually until all remaining variables were significant (p < 0.05). RESULTS: Among 1832 TNFi initiations, 774 initiations (624 patients) met inclusion criteria. Median age at initiation was 52 years [interquartile range (IQR) 44-60], 56% were female, median PsA duration was 4 years (IQR 2-11), and median CDAI at baseline was 20 (IQR 14.5-28). Remission was achieved by 14% and LDA (or remission) by 37%. Achieving remission was positively associated with college education (OR 1.88, 95% CI 1.11-3.19) but negatively associated with female sex (0.62, 95% CI 0.40-0.97), obese body mass index (0.51, 95% CI 0.32-0.81), hypertension (0.55, 95% CI 0.32-0.95), previous biologic use (0.41, 95% CI 0.26-0.65), and baseline pain (0.80 per 10 mm visual analog scale, 95% CI 0.73-0.87). Predictors for LDA, mHAQ < 0.30, and mHAQ change were similar. CONCLUSION: Few patients with PsA in a US-based registry achieved remission by CDAI criteria. Female sex, obesity, comorbidities, and education influence achievement of remission on a TNFi.

RESUMO

INTRODUCTION: Traditional markers of inflammation are often required for inclusion in rheumatoid arthritis trials, yet patients with active disease may have normal lab tests. The potential use of the multi-biomarker disease activity (MBDA) test in this setting is unclear, as is understanding of whether it is influenced by patient characteristics (e.g., age, BMI, and comorbidities). METHODS: Using data from the Corrona registry, we conducted a cross-sectional analysis of RA patients with MBDA tests. Patients were classified as low (<30), moderate (30-44, and high (>44) and by clinical and RA-related factors. Regression was used to evaluate the association between MBDA score and age, body mass index, comorbidities, and RA-related factors. RESULTS: Of 357 eligible patients, 76% (n = 273) had normal CRP (<10mg/L) with high (33%), moderate (45%), and low (22%) disease activity by MBDA. The MBDA score was significantly associated with BMI, age, CDAI, and SJC. There was no association between MBDA score and fibromyalgia, diabetes, smoking, or COPD; none were confounders between MBDA score and either SJC or CDAI. For patients in CDAI remission, older age (2.6 units per decade; p = 0.03) and obesity (ß = 10.5 for BMI > 30, referent to <25; p = 0.02) were independently associated with MBDA score. An adjusted MBDA score was proposed that was highly correlated with the original MBDA (r = 0.91). CONCLUSION: In this real-world analysis, the MBDA score was associated with RA disease activity, obesity, and age, and was negligibly affected by common comorbidities. Almost one-third of patients with normal CRP had high MBDA scores. An adjustment to the MBDA score to account for body mass index and age is proposed.

RESUMO

INTRODUCTION: Previous studies have shown that autonomic dysfunction is associated with shorter survival in patients with advanced cancer. We examined the association between heart rate variability, a measure of autonomic function, and survival in a large cohort of patients with cancer. METHODS: We retrospectively examined the records of 651 patients with cancer who had undergone ambulatory electrocardiogram monitoring for 20 to 24 hours. Time domain heart rate variability (SD of normal-to-normal beat interval [SDNN]) was calculated using power spectral analysis. Survival data were compared between patients with SDNN ≥ 70 milliseconds (Group 1, n = 520) and SDNN < 70 milliseconds (Group 2, n = 131). RESULTS: Two groups were similar in most variables, except that patients in group 2 had a significantly higher percentage of male patients (P = 0.03), hematological malignancies (P = 0.04), and use of non-selective serotonin reuptake inhibitor antidepressants (P = 0.04). Patients in group 2 had a significantly shorter survival rate (25% of patients in group 2 died by 18.7 weeks vs. 78.9 weeks in group 1 patients; P < 0.0001). Multivariate analysis showed that SDNN < 70 milliseconds remained significant for survival (hazard ratio 1.9 [95% confidence interval: 1.4-2.5]) independent of age, cancer stage, and performance status. CONCLUSION: The presence of cancer in combination with decreased heart rate variability (SDNN < 70 milliseconds) is associated with shorter survival time.

RESUMO

OBJECTIVE: This multi-site randomized trial evaluates the quality of life (QOL) benefits of an imagery-based group intervention titled 'Envision the Rhythms of Life'(ERL). METHODS: Breast cancer survivors >6 weeks post-treatment were randomized to attend five weekly 4-h group sessions at a community center with therapist present (live delivery (LD), n = 48), therapist streamed via telemedicine (telemedicine delivery (TD), n = 23), or to a waitlist control (WL) group (n = 47). Weekly individual phone calls to encourage at-home practice began at session one and continued until the 3-month follow-up. Seven self-report measures of QOL were examined at baseline, 1-month and 3-month post-treatments including health-related and breast cancer-specific QOL, fatigue, cognitive function, spirituality, distress, and sleep. RESULTS: The Bonferroni method was used to correct for multiple comparisons, and alpha was adjusted to 0.01. Linear multilevel modeling analyses revealed less fatigue, cognitive dysfunction, and sleep disturbance for LD and TD compared with WL across the follow-up (p's < 0.01). Changes in fatigue, cognitive dysfunction, sleep disturbance, and health-related and breast cancer-related QOL were clinically significant. There were no differences between LD and TD. CONCLUSIONS: Both the live and telemedicine delivered ERL intervention resulted in improvements in multiple QOL domains for breast cancer survivors compared with WL. Further, there were no significant differences between LD and TD, suggesting telemedicine delivered ERL intervention may represent an effective and viable option for cancer survivors in remote areas.

RESUMO

INTRODUCTION: The sural/radial nerve amplitude ratio (SRAR) is the quotient of the sensory nerve action potential (SNAP) amplitudes (Amp) of the sural and the superficial radial nerve. It has been hypothesized that this ratio can be used for the detection of early axonal loss, because the sural SNAP amplitude will decrease first, thereby also decreasing the SRAR value. OBJECTIVES: To determine the sensitivity and specificity of SRAR, age-adjusted sural and radial SNAP Amp in the diagnosis of axonal sensory polyneuropathy in cancer patients. DESIGN: Retrospective review. SETTING: Comprehensive cancer center. PATIENTS: One hundred and ninety one EMG reports from January 2001 to December 2005. METHODS: The independent variable is the diagnosis of axonal sensory polyneuropathy in the EMG reports that is based on multiple tests. MAIN OUTCOME MEASUREMENTS: We assessed the agreement between classifications of axonal sensory polyneuropathy made using the current 'gold standard' and the proposed method that is based on patients' age-adjusted radial and sural SNAP amplitude; an SRAR being above or below the normal value (0.21). RESULTS: We found that the sensitivities for age-adjusted radial SNAP Amp, age-adjusted sural SNAP Amp, and SRAR were 33%, 64%, 56% respectively; the specificities were 85%, 70%, 77% respectively. CONCLUSIONS: SRAR is neither the most sensitive, nor the most specific in the diagnosis of axonal sensory polyneuropathy.

RESUMO

OBJECTIVES: Chemotherapy-induced peripheral neuropathy is frequently a dose-limiting factor in cancer treatment and may cause pain and irreversible function loss in cancer survivors. We tested whether alpha-lipoic acid (ALA) could decrease the severity of peripheral neuropathy symptoms in patients undergoing platinum-based chemotherapy. METHODS: Cancer patients 18 years or older were randomly selected to receive either 600 mg ALA or a placebo three times a day orally for 24 weeks while receiving chemotherapy regimens including cisplatin or oxaliplatin. Neuropathy was measured by the Functional Assessment of Cancer Therapy/Gynecologic Oncology Group-Neurotoxicity (FACT/GOG-Ntx) scale and the NCI Common Toxicity Criteria for Adverse Events neurotoxicity grades. Results from timed functional tests and the Brief Pain Inventory (BPI) were secondary endpoints. RESULTS: Seventy of 243 (29 %) patients completed the study (24 weeks). Both the ALA and the placebo arms had a comparable drop-out rate. No statistically significant differences were found between the ALA and the placebo groups for FACT/GOG-Ntx scores, BPI scores, and patients' functional outcomes. CONCLUSION: This strategy of oral ALA administration was ineffective at preventing neurotoxicity caused by oxaliplatin or cisplatin. High attrition rates due to poor patient compliance and manner of dosage administration in this trial demonstrated a lack of feasibility for this intervention. Future studies to explore ALA as a neuroprotective agent should take heed of the barriers confronted in this study.

RESUMO

CONTEXT: Studies to determine the decisional control preferences (DCPs) in Hispanic patients receiving palliative care are limited. OBJECTIVES: The aims of this study were to describe DCPs, disclosure of information, and satisfaction with decision making among Hispanics and to determine the degree of concordance between patients' DCPs and their self-reported decisions. METHODS: We surveyed 387 cancer patients referred to outpatient palliative care clinics in Argentina, Chile, Guatemala, and the U.S. DCPs were measured with the Control Preference Scale, disclosure preferences with the Disclosure of Information Preferences questionnaire, and satisfaction with care with the Satisfaction with Decision Scale. RESULTS: In this study, 182 patients (47.6%) preferred shared decisional control, 119 (31.2%) preferred active decisional control, and 81 (21.2%) preferred a passive approach. Concerning their diagnosis and prognosis, 345 (92%) patients wanted to know their diagnosis, and 355 (94%) wanted to know their prognosis. Three hundred thirty-seven (87%) patients were satisfied with the decision-making process. DCPs were concordant with the self-reported decision-making process in 264 (69%) patients (weighted kappa = 0.55). Patients' greater satisfaction with the decision-making process was correlated with older age (P ≤ 0.001) and with a preference for enhanced diagnostic disclosure (P ≤ 0.024). Satisfaction did not correlate with concordance in the decision-making process. CONCLUSION: The vast majority preferred a shared or active decision-making process and wanted information about their diagnosis and prognosis. Older patients and those who wanted to know their diagnosis seemed to be more satisfied with the way treatment decisions were made.

RESUMO

PURPOSE: Pain control is an ongoing challenge in the oncology setting. Prior to implementing a large randomized trial at our institution, we investigated the feasibility, safety, and initial efficacy of acupuncture for uncontrolled pain among cancer patients. HYPOTHESES: Our hypotheses were that the acupuncture treatments provided would be ( : ) feasible, ( : ) safe, and ( : ) a beneficial adjunct to pain management. STUDY DESIGN: This was a single arm, nonrandomized pragmatic pilot study. METHODS: Participants experiencing pain ≥4 on a 0 to 10 numeric rating scale received a maximum of 10 treatments on an individualized basis. Recruitment, attrition, compliance, and adverse events (AEs) were assessed. Pain (Brief Pain Inventory-Short Form), quality of life (MD Anderson Symptom Inventory [MDASI]), and patient satisfaction were assessed at baseline and at the end of treatment. RESULTS: Of 115 patients screened, 52 (45%) were eligible and agreed to participate. Eleven (21%) were lost to follow-up, leaving 41 who completed all study procedures. No AEs were reported. Mean pain SEVERIT: was 6.0 ± 1.3 at baseline and 3.8 ± 2.0 at follow-up ( : < .0001). Pain INTERFERENC: was 6.2 ± 2.3 at baseline and 4.3 ± 2.8 at follow-up ( : < .0011). On the MDASI, the mean symptom SEVERIT: was 4.6 ± 1.8 at baseline and 3.2 ± 1.9 at follow-up ( : < .0001), and mean symptom INTERFERENC: was 5.8 ± 2.4 at baseline and 4.1 ± 2.9 at follow-up ( : < .002). Prescribed pain medications decreased across the course of the study. Patient satisfaction was high: 87% reported that their expectations were met "very well" or "extremely well"; 90% said they were likely to participate again; 95% said they were likely to recommend acupuncture to others; and 90% reported they found the service to be "useful" or "very useful." CONCLUSIONS: Acupuncture was feasible, safe, and a helpful treatment adjunct for cancer patients experiencing uncontrolled pain in this study. Randomized placebo-controlled trials are needed to confirm these results.

RESUMO

PURPOSE: Cancer-related fatigue (CRF) is the most common symptom in patients with advanced cancer. The primary objective of this prospective, randomized, double-blind, placebo-controlled study was to compare the effect of dexamethasone and placebo on CRF. PATIENTS AND METHODS: Patients with advanced cancer with ≥ three CRF-related symptoms (ie, fatigue, pain, nausea, loss of appetite, depression, anxiety, or sleep disturbance) ≥ 4 of 10 on the Edmonton Symptom Assessment Scale (ESAS) were eligible. Patients were randomly assigned to either dexamethasone 4 mg or placebo orally twice per day for 14 days. The primary end point was change in the Functional Assessment of Chronic Illness-Fatigue (FACIT-F) subscale from baseline to day 15. Secondary outcomes included anorexia, anxiety, depression, and symptom distress scores. RESULTS: A total of 84 patients were evaluable (dexamethasone, 43; placebo, 41). Mean (± standard deviation) improvement in the FACIT-F subscale at day 15 was significantly higher in the dexamethasone than in the placebo group (9 [± 10.3] v 3.1 [± 9.59]; P = .008). The improvement in FACIT-F total quality-of-life scores was also significantly better for the dexamethasone group at day 15 (P = .03). The mean differences in the ESAS physical distress scores at day 15 were significantly better for the dexamethasone group (P = .013, respectively). No differences were observed for ESAS overall symptom distress (P = .22) or psychological distress score (P = .76). Frequency of adverse effects was not significantly different between groups (41 of 62 v 44 of 58; P = .14). CONCLUSION: Dexamethasone is more effective than placebo in improving CRF and quality of life in patients with advanced cancer.

RESUMO

BACKGROUND: Understanding family caregivers' decisional role preferences is important for communication, quality of care, and patient and family satisfaction. The family caregiver has an important role in a patient's decisional role preferences. There are limited studies on family caregivers' preferences of the patient's decision control at the end of life among Hispanics. AIMS: To identify Hispanic caregivers' preferences of the decision control of patients with advanced cancer and to compare the preferences of caregivers in Hispanic Latin American and Hispanic American caregivers. DESIGN: We surveyed patients and their family caregivers referred to outpatient palliative care clinics in the United States, Chile, Argentina, and Guatemala. Caregiver preferences of patient's decision control were evaluated using the Control Preference Scale. Caregivers' and patients' sociodemographic variables, patient performance status, and Hispanic American patient acculturation level were also collected. PARTICIPANTS: A total of 387 caregivers were surveyed: 100 (26%) in Chile, 99 (26%) in Argentina, 97 (25%) in Guatemala, and 91 (24%) in the United States. The median age was 56 years, and 59% were female. RESULTS: Caregiver preference of patient's decision control was passive, shared, and active for 10 (11%), 45 (52%), and 32 (37%) Hispanic American caregivers and 54 (19%), 178 (62%), and 55 (19%) Hispanic Latin American caregivers (p = 0.0023), respectively. Caregiver acculturation level did not affect the preferences of the Hispanic American sample (p = 0.60). CONCLUSIONS: Most Hispanic family caregivers preferred the patient to make shared decisions. Hispanic Latin American caregivers more frequently preferred patients to assume a passive decisional role. Acculturation did not influence the preferences of Hispanic American caregivers.

RESUMO

PURPOSE: Cancer-related-fatigue (CRF) is common in advanced cancer. The primary objective of the study was to compare the effects of methylphenidate (MP) with those of placebo (PL) on CRF as measured using the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) fatigue subscale. The effect of a combined intervention including MP plus a nursing telephone intervention (NTI) was also assessed. PATIENTS AND METHODS: Patients with advanced cancer with a fatigue score of ≥ 4 out of 10 on the Edmonton Symptom Assessment Scale (ESAS) were randomly assigned to one of the following four groups: MP+NTI, PL+NTI, MP + control telephone intervention (CTI), and PL+CTI. Methylphenidate dose was 5 mg every 2 hours as needed up to 20 mg per day. The primary end point was the median difference in FACIT-F fatigue at day 15. Secondary outcomes included anxiety, depression, and sleep. RESULTS: One hundred forty-one patients were evaluable. Median FACIT-F fatigue scores improved from baseline to day 15 in all groups: MP+NTI (median score, 4.5; P = .005), PL+NTI (median score, 8.0; P < .001), MP+CTI (median score, 7.0; P = .004), and PL+CTI (median score, 5.0; P = .03). However, there were no significant differences in the median improvement in FACIT-F fatigue between the MP and PL groups (5.5 v 6.0, respectively; P = .69) and among all four groups (P = .16). Fatigue (P < .001), nausea (P = .01), depression (P = .02), anxiety (P = .01), drowsiness (P < .001), appetite (P = .009), sleep (P < .001), and feeling of well-being (P < .001), as measured by the ESAS, significantly improved in patients who received NTI. Grade ≥ 3 adverse events did not differ between MP and PL (40 of 93 patients v 29 of 97 patients, respectively; P = .06). CONCLUSION: MP and NTI alone or combined were not superior to placebo in improving CRF.

RESUMO

CONTEXT: Bone metastases (BM) can cause severe pain, spinal cord compression, pathological fractures, and/or hypercalcemia. These skeletal-related events (SREs) may cause immobilization, loss of independence, poor quality of life, and reduced survival. There is limited information on the clinical effects of BM and SREs in patients with malignant pheochromocytoma or sympathetic paraganglioma (PHEO/sPGL). OBJECTIVES: We studied the prevalence and clinical characteristics of BM and SREs in patients with PHEO/sPGL and investigated the risk factors for SRE development. DESIGN: Using a large institutional database, we conducted a retrospective study of 128 patients with malignant PHEO/sPGL at The University of Texas MD Anderson Cancer Center from 1967 through 2011. RESULTS: Of the patients, 91 (71%) had BM, and 57 of these (63%) developed metachronous BM at a median time of 3.4 years (range, 5 months to 23 years) after the primary tumor diagnosis. Metastatic disease was confined exclusively to the skeleton in 26 of 128 (20%) patients. Sufficient information to assess SRE occurrence was available for 67 patients, and 48 of 67 (72%) patients had at least 1 SRE. The median overall survival for the 128 patients was 12 years for patients with only BM, 7.5 years for patients with nonosseous metastases, and 5 years for patients with both BM and nonosseous metastases (log rank test P value = .005). We were unable to identify factors predictive of SRE development, but the occurrence of a first SRE was associated with the development of subsequent SREs in 48% of subjects. In responsive patients, the use of systemic therapy was associated with fewer SREs (P < .0001). CONCLUSIONS: BM and SREs are frequent in patients with malignant PHEO/sPGL. SREs often develop shortly after the diagnosis of BM; severe pain is the most frequent SRE. These patients should be followed long-term by a multidisciplinary team to promptly identify the need for medical or surgical intervention.

RESUMO

PURPOSE: Many cancer centers offer acupuncture services. To date, a comprehensive systematic review of acupuncture in cancer care has not been conducted. The purpose of this review was to evaluate the efficacy of acupuncture for symptom management in patients with cancer. METHODS: Medline, Embase, CINAHL, Cochrane (all databases), Scopus, and PubMed were searched from inception through December 2011 for prospective randomized clinical trials (RCT) evaluating acupuncture for symptom management in cancer care. Only studies involving needle insertion into acupuncture points were included. No language limitations were applied. Studies were assessed for risk of bias (ROB) according to Cochrane criteria. Outcomes by symptom were designated as positive, negative, or unclear. RESULTS: A total of 2,151 publications were screened. Of those, 41 RCTs involving eight symptoms (pain, nausea, hot flashes, fatigue, radiation-induced xerostomia, prolonged postoperative ileus, anxiety/mood disorders, and sleep disturbance) met all inclusion criteria. One positive trial of acupuncture for chemotherapy-induced nausea and vomiting had low ROB. Of the remaining studies, eight had unclear ROB (four positive, three negative, and one with unclear outcomes). Thirty-three studies had high ROB (19 positive, 11 negative, and three with both positive and negative outcomes depending on the symptom). CONCLUSION: Acupuncture is an appropriate adjunctive treatment for chemotherapy-induced nausea/vomiting, but additional studies are needed. For other symptoms, efficacy remains undetermined owing to high ROB among studies. Future research should focus on standardizing comparison groups and treatment methods, be at least single-blinded, assess biologic mechanisms, have adequate statistical power, and involve multiple acupuncturists.

RESUMO

PURPOSE: The vast majority of patients with cancer at the end of life receive parenteral hydration in hospitals and no hydration in hospice, with limited evidence supporting either practice. In this randomized controlled trial, we determined the effect of hydration on symptoms associated with dehydration, quality of life, and survival in patients with advanced cancer. PATIENTS AND METHODS: We randomly assigned 129 patients with cancer from six hospices to receive parenteral hydration (normal saline 1 L per day) or placebo (normal saline 100 mL per day) daily over 4 hours. The primary outcome was change in the sum of four dehydration symptoms (fatigue, myoclonus, sedation and hallucinations, 0 = best and 40 = worst possible) between day 4 and baseline. Secondary outcomes included Edmonton Symptom Assessment Scale (ESAS), Memorial Delirium Assessment Scale (MDAS), Nursing Delirium Screening Scale (NuDESC), Unified Myoclonus Rating Scale (UMRS), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), Dehydration Assessment Scale, creatinine, urea, and overall survival. Intention-to-treat analysis was conducted to examine the change by day 4 ± 2 and day 7 ± 2 between groups. RESULTS: The hydration (n = 63) and placebo (n = 66) groups had similar baseline characteristics. We found no significant differences between the two groups for change in the sum of four dehydration symptoms (-3.3 v -2.8, P = .77), ESAS (all nonsignificant), MDAS (1 v 3.5, P = .084), NuDESC (0 v 0, P = .13), and UMRS (0 v 0, P = .54) by day 4. Results for day 7, including FACIT-F, were similar. Overall survival did not differ between the two groups (median, 21 v 15 days, P = .83). CONCLUSION: Hydration at 1 L per day did not improve symptoms, quality of life, or survival compared with placebo.

RESUMO

CONTEXT: Understanding cancer patients' preferences in decisional roles is important in providing quality care and ensuring patient satisfaction. There is a lack of evidence on decisional control preferences (DCPs) of Hispanic Americans, the fastest growing population in the U.S. OBJECTIVES: The primary aims of this study were to describe DCPs of Hispanics with advanced cancer in the U.S. (HUSs) and compare the frequency of passive DCPs in this population with that of Hispanics with advanced cancer in Latin America (HLAs). METHODS: We conducted a prospective survey of patients with advanced cancer referred to outpatient palliative care clinics in the U.S., Chile, Argentina, and Guatemala. Information was collected on sociodemographic variables, Karnofsky Performance Scale scores, acculturation (Marin Acculturation Assessment Tool), and DCP (Control Preference Scale). Chi-square tests were used to determine the differences in DCPs between HUSs and HLAs. RESULTS: A total of 387 patients were surveyed: 91 in the U.S., 100 in Chile, 94 in Guatemala, and 99 in Argentina. The median age of HUSs was 56 years, 59% were female, and the median Karnofsky Performance Scale score was 60; the corresponding values for HLAs were 60 years, 60%, and 80. HLAs used passive DCP strategies significantly more frequently than HUSs did with regard to the involvement of the family (24% vs. 10%; P=0.009) or the physician (35% vs. 16%; P<0.001), even after age and education were controlled for. Eighty-three percent of HUSs and 82% of HLAs preferred family involvement in decision making (P=non-significant). No significant differences were found in DCPs between poorly and highly acculturated HUSs (P=0.91). CONCLUSION: HUSs had more active DCPs than HLAs did. Among HUSs, acculturation did not seem to play a role in DCP determination. Our findings confirm the importance of family participation for both HUSs and HLAs. However, HUSs were less likely to want family members to make decisions on their behalf.

RESUMO

Background. In China, the use of traditional Chinese medicine (TCM) is very popular, but little is known about how it is integrated with conventional cancer care. We conducted parallel surveys of patients and physicians on TCM utilization. Methods. Two hundred forty-five patients and 72 allopathic physicians at the Fudan University Shanghai Cancer Center completed questions on their use of and attitude towards TCM. Results. Patient mean age was 51, with 60% female. Eighty-three percent of patients had used TCM. Use was greatest for Chinese herbal medicine (CHM; 55.8%). Only 1.3% of patients used acupuncture and 6.8% Qi Gong or Tai Qi. Sixty-three percent of patients notified their oncologist about TCM use. The most common reason for use was to improve immune function. CHM was often used with a goal of treating cancer (66.4%), a use that 57% of physicians agreed with. Physicians were most concerned with interference with treatment, lack of evidence, and safety. Ninety percent of physicians have prescribed herbs and 87.5% have used TCM themselves. Conclusion. The use of TCM by Chinese cancer patients is exceptionally high, and physicians are generally well informed and supportive of patients' use. Botanical agents are much more commonly used than acupuncture or movement-based therapies.

RESUMO

CONTEXT: Patients with progressive metastatic pheochromocytomas (PHEOs) or sympathetic paragangliomas (SPGLs) face a dismal prognosis. Current systemic therapies are limited. OBJECTIVES: The primary end point was progression-free survival determined by RECIST 1.1 criteria or positron emission tomography with [(18)F]fluorodeoxyglucose/computed tomography ([(18)F]FDG-PET/CT), in the absence of measurable soft tissue targets. Secondary endpoints were tumor response according to RECIST criteria version 1.1 or FDG uptake, blood pressure control, and safety. DESIGN: We conducted a retrospective review of medical records of patients with metastatic PHEO/SPGL treated with sunitinib from December 2007 through December 2011. An intention-to-treat analysis was performed. PATIENTS AND SETTING: Seventeen patients with progressive metastatic PHEO/SPGLs treated at the Institut Gustave-Roussy and MD Anderson Cancer Center. INTERVENTIONS: Patients treated with sunitinib. RESULTS: According to RECIST 1.1, eight patients experienced clinical benefit; three experienced partial response, and five had stable disease, including four with predominant skeletal metastases that showed a 30% or greater reduction in glucose uptake on [(18)F]FDG-PET/CT. Of 14 patients who had hypertension, six became normotensive and two discontinued antihypertensives. One patient treated with sunitinib and rapamycin experienced a durable benefit beyond 36 months. The median overall survival from the time sunitinib was initiated was 26.7 months with a progression-free survival of 4.1 months (95% confidence interval = 1.4-11.0). Most patients who experienced a clinical benefit were carriers of SDHB mutations. CONCLUSION: Sunitinib is associated with tumor size reduction, decreased [(18)F]FDG-PET/CT uptake, disease stabilization, and hypertension improvement in some patients with progressive metastatic PHEO/PGL. Prospective multi-institutional clinical trials are needed to determine the true benefits of sunitinib.

RESUMO

OBJECTIVES: To determine the effects of thalidomide and placebo on anorexia-cachexia and its related symptoms, body composition, resting metabolic rate, and serum cytokines and their receptors in patients with advanced cancer. METHODS: Included in the study were patients with advanced cancer with weight loss greater than 5% in 6 months and who reported anorexia, fatigue, and one of the following: anxiety, depression, or sleep disturbances. Patients on chemotherapy within 2 weeks prior or during the study were excluded from the study. Patients were randomly assigned to either 100 mg thalidomide or placebo once a day for 14 days. The Edmonton Symptom Assessment Scale (ESAS), Functional Assessment of Anorexia/Cachexia Therapy (FAACT), Functional Assessment of Cancer Illness Therapy (FACIT-F), Hospital Anxiety Depression Scale (HADS) Pittsburgh Sleep Quality Index (PSQI) were utilized, and in addition body composition, Resting Energy Expenditure (REE), and serum cytokine levels were assessed. RESULTS: Of the 31 patients entered in the study, 15 were assigned to the thalidomide group and 16 to the placebo group. However only 21/31 patients were able to complete the study. Compared with their baseline values, both the thalidomide and the placebo groups showed significant reduction in cytokines. Tumor necrosis factor (TNF)-α (p=0.04) and its receptors TNFR1 (p=0.04), TNFR2 (p=0.04), and interleukin (IL)-8 (p=0.04) were statistically significant in the thalidomide group. In the placebo group, TNF-α (p=0.008), TNFR1 (p=0.005), TNFR2 (p=0.005), IL-RA (p=0.005), IL-6 (p=0.005), and IL-8 (p=0.005) were statistically significant. However, improvement in these symptoms and cytokine levels were not significantly different in the thalidomide group compared with the placebo group. None of the patients withdrew from the study because of toxicity of either thalidomide or placebo. CONCLUSIONS: Based on the poor accrual rate and attrition observed in this study, it is important that future research on thalidomide as a treatment for cancer-related anorexia-cachexia symptoms (ACS) in patients with advanced cancer use less stringent entry criteria and less exhaustive outcome measures.

RESUMO

BACKGROUND: Xerostomia (dry mouth) after head/neck radiation is a common problem among cancer patients, and available treatments are of little benefit. The objective of this trial was to determine whether acupuncture can prevent xerostomia among head/neck patients undergoing radiotherapy. METHODS: A randomized, controlled trial among patients with nasopharyngeal carcinoma was conducted comparing acupuncture to standard care. Participants were treated at Fudan University Shanghai Cancer Center, Shanghai, China. Forty patients were randomized to acupuncture treatment and 46 to standard care. Patients were treated 3×/wk on the same days they received radiotherapy. Subjective measures included the Xerostomia Questionnaire and MD Anderson Symptom Inventory-Head and Neck (MDASI-HN). Objective measures were unstimulated and stimulated whole salivary flow rates. Patients were followed for 6 months after the end of radiotherapy. RESULTS: Xerostomia Questionnaire scores for acupuncture were statistically significantly lower than for controls starting in week 3 through the 6 months (P = .003 at week 3, all other P < .0001), with clinically significant differences as follows: week 11, relative risk (RR) 0.63 (95% confidence interval [CI], 0.45-0.87); 6 months, RR 0.38 (95% CI, 0.19-0.76). Similar findings were seen for MDASI-HN scores. Group differences emerged as early as 3 weeks into treatment for saliva (unstimulated whole salivary flow rate, P = .0004), with greater saliva flow in the acupuncture group at week 7 (unstimulated whole salivary flow rate, P < .0001; stimulated whole salivary flow rate, P = .002) and 11 (unstimulated whole salivary flow rate, P < .02; stimulated whole salivary flow rate, P < .03) and at 6 months (stimulated whole salivary flow rate, P < .003). CONCLUSIONS: Acupuncture given concurrently with radiotherapy significantly reduced xerostomia and improved quality of life.
