Use of a web-based app to improve postoperative outcomes for patients receiving gynecological oncology care: A randomized controlled feasibility trial.

OBJECTIVE: Nearly 1 in 5 patients hospitalized for ovarian cancer surgery are readmitted for complications that may have been prevented with monitoring. We conducted a randomized controlled feasibility trial to evaluate a postoperative web-based app intervention to provide real-time symptom monitoring among patients diagnosed or with suspected gynecological cancer who had open bilateral salpingo-oophorectomy surgery. METHODS: Participants were randomized into two groups: (1) App + Reminder: had access to the app, and use was encouraged with daily and/or weekly reminders; (2) app: had access to the app but received no reminders. The app displayed discharge instructions and queried symptoms. Patients' self-reported health information was integrated into their electronic health records. Outcomes above a predetermined threshold triggered alerts that indicated a patient may need medical intervention. Participants completed a questionnaire at baseline and 30-day follow-up. They were also invited to provide qualitative, post-intervention feedback. RESULTS: We screened 35 patients, with high rates of recruitment (74%, N = 26) and completion (93%, N = 24). Participants in the App + Reminder group had more frequent app use relative to the app group (p = 0.05). Using differences-in-differences (DID) analysis for quality of life, the App + Reminder group had relative increase in the mental health score (DID = 7.51, p = 0.15) but decrease in the physical health score (DID = -7.49, p = 0.13). Participant feedback suggested the relative decrease in physical quality of life was attributable to the app activating patients' focus on physical symptoms, not the intervention. CONCLUSION: The pilot established feasibility, acceptability, and some potential benefits of a new web-based app intervention for gynecological oncology postoperative care.

Results of a prospective phase 2 study of pazopanib in patients with advanced intermediate-grade or high-grade liposarcoma.

BACKGROUND: This phase 2, single-arm, multicenter study was designed to determine the treatment activity and safety of single-agent pazopanib in patients with unresectable or metastatic liposarcoma. METHODS: Eligible patients had high-grade or intermediate-grade liposarcoma with measurable tumors that were unresectable or metastatic, documented disease progression, and had received any number of prior treatments, excluding previous treatment with a vascular endothelial growth factor inhibitor or a tyrosine kinase inhibitor. Patients received oral pazopanib 800 mg once daily for 28-day cycles. Tumor response was evaluated by local radiology assessments every 3 cycles. The primary endpoint was the progression-free rate (PFR) at 12 weeks (PFR12). RESULTS: Forty-one patients were enrolled. The PFR12 was 68.3% (95% confidence interval [CI], 51.9%-81.9%), which was significantly greater than the null hypothesis value of 40% (P = .0002). At 24 weeks, 39% of patients (95% CI, 24.2%-55.5%) remained progression free, and 44% experienced tumor control (partial response or stable disease). The median progression-free survival was 4.4 months (95% CI, 3.2-6.5 months), and the median overall survival was 12.6 months (95% CI, 8.5-16.2 months). The most common adverse events overall were nausea (39%), hypertension (36.6%), diarrhea (34.1%), and fatigue (29.3%), which were typically less than grade 3. There were 5 deaths on study (12.2%), 3 of which were from possible complications of therapy. CONCLUSIONS: The current study provides evidence of potential activity of pazopanib in the liposarcoma subset of patients with soft tissue sarcoma that was specifically excluded from the phase 3 PALETTE trial of other soft tissue sarcoma types.

mHealth: Mobile Technologies to Virtually Bring the Patient Into an Oncology Practice.

Accompanied by the change in the traditional medical landscape, advances in wireless technology have led to the development of telehealth or mobile health (mHealth), which offers an unparalleled opportunity for health care providers to continually deliver high-quality care. This revolutionary shift makes the patient the consumer of health care and empowers patients to be the driving force of management of their own health through mobile devices and wearable technology. This article presents an overview of technology as it pertains to clinical practice considerations. Telemedicine is changing the way clinical care is delivered without regard for proximity to the patient, whereas nonclinical telehealth applications affect distance education for consumers or clinicians, meetings, research, continuing medical education, and health care management. Technology has the potential to reduce administrative burdens and improve both efficiency and quality of care delivery in the clinic. Finally, the potential for telehealth approaches as cost-effective ways to improve adherence to treatment is explored. As telehealth advances, health care providers must understand the fundamental framework for applying telehealth strategies to incorporate into successful clinical practice.

Analysis of the psychological impact of cancer-related symptoms on patients with non-small cell lung cancer.

BACKGROUND: Patients with non-small cell lung cancer (NSCLC) experience adverse physical symptoms because of cancer, cancer treatment, and comorbidities. The relations among Cancer-Related Symptoms, Functional Impairment, and Psychological Symptoms in patients with NSCLC is not well understood. METHODS: Retrospective analysis of patient-reported symptoms with the 38-item Patient Care Monitor survey, collected in routine clinical care for 1138 patients with NSCLC at eight US community oncology practices. Study sample was randomly split, and structural equation models examined the direct and mediated effects of Cancer-Related Symptoms and Functional Impairment on symptoms of acute distress (Distress) and depression (Despair) in the training sample. The training model was cross validated in testing sample. Results are presented for the full model using the entire sample. RESULTS: Patients were 48.3% female, with mean age of 66.0 years. The most common comorbidities were anemia (60.8%) and respiratory disease (24.5%). Severity of Cancer-Related Symptoms was strongly and positively related to Functional Impairment and Psychological Symptoms in both training and testing models. The modeled effect of Functional Impairment on Distress and Despair was significant in the overall model using the total sample, and significant or near-significant in the training and testing models. The mediated effect of Cancer-Related Symptoms by Functional Impairment tended to be weaker than its direct modeled effect on Distress and Despair. CONCLUSIONS: Despite prior research suggesting that Functional Impairment plays a larger role than symptom burden in depression in NSCLC, the independent modeled effects of Functional Impairment were no greater than the direct modeled effects of Cancer-Related Symptoms.

Treatment patterns and outcomes among patients with metastatic melanoma treated in community practice.

BACKGROUND: The primary systemic treatments for advanced melanoma have been chemotherapy and immunotherapy. New agents are currently in development. OBJECTIVES: This study aimed to characterize treatment patterns and outcomes across several lines of therapy and to illustrate the treatment landscape prior to the approval of new therapies. The study endpoints were progression-free survival (PFS), overall survival (OS), and best overall response within line of therapy. METHODS: A retrospective chart analysis was conducted at 11 community oncology practices in the USA. Data for patients aged ≥18 years and diagnosed with stage IV and/or metastatic melanoma during 2006-2010 were analyzed. Primary endpoints were PFS within line of therapy and OS from the diagnosis of metastasis. RESULTS: Data on a total of 202 patients were collected. The sample was mostly male (60%) and Caucasian (88%), with a mean age of 61.3 years. Of the 202 patients, 56 (28%) never received any systemic therapy. In the remaining 146 patients, systemic therapies included temozolomide-based regimens (n = 68), platinum-based regimens without temozolomide (n = 16), other regimens (n = 23), and research regimens (n = 39). Of the 146 patients who received systemic therapy, not all did so immediately after the diagnosis of metastasis: 102 (51%) patients did so shortly after diagnosis and before first disease progression, and 44 (22%) did so after first disease progression. Response rates were very low (≤5%) and did not differ across treatment groups. Progressive disease was the most frequent best overall response category identified, with rates of 83, 78, and 89% in the first to third lines of treatment, respectively. In 146 patients receiving first-line systemic therapy, median PFS was 3.25 months. Median OS in the entire sample was 7.66 months. CONCLUSIONS: Findings provided little evidence for any beneficial effects of the treatments available in the timeframe referred to in this study. Few patients (≤5%) responded to treatment, PFS among treated patients was short (3.25 months in first-line treatments, less in later lines), and there was no evidence of a differential effect of treatment regimens on PFS. There was no evidence of shorter survival in patients who never received systemic therapy. The high proportion of patients who did not receive any systemic therapy highlights the lack of effective therapies and underscores the unmet medical need in this patient population.

Phase II trial of fulvestrant with metronomic capecitabine for postmenopausal women with hormone receptor-positive, HER2-negative metastatic breast cancer.

BACKGROUND: In this phase II study, we explored efficacy and toxicity of combined endocrine and low-dose metronomic chemotherapy therapy consisting of fulvestrant and capecitabine in estrogen and/or progesterone receptor-positive, HER2-negative MBC. PATIENTS AND METHODS: Patients with ≤ 1 previous hormonal treatment in the metastatic setting received an injection fulvestrant loading dose 500 mg on day 1, 250 mg on days 15 and 29 followed by 250 mg every 28 days along with continuous oral capecitabine in divided doses. The total fixed daily dose of capecitabine was either 1500 mg or 2000 mg, depending on the patient's weight (< 80 kg vs. ≥ 80 kg). Primary end points were PFS and TTP. Toxicity was assessed by continuous evaluations of treatment-emergent adverse events (AEs) and changes from baseline in laboratory values. RESULTS: Forty-one women, with a mean age of 64.5 years, were enrolled. Patients completed a median of 11 monthly treatment cycles. Median PFS was 14.98 months (95% confidence interval [CI], 7.26-upper limit [UL] not estimated) and median TTP was 26.94 months (95% CI, 7.26-UL not estimated). Median overall survival was 28.65 months (95% CI, 23.95-UL not estimated). Treatment was well tolerated with < 10% Grade 3 palmar-plantar erythrodysesthesia. Overall, the most frequent AEs were palmar-plantar erythrodysesthesia, fatigue, and nausea. CONCLUSION: Fulvestrant with metronomic capecitabine demonstrates substantial activity in hormone receptor-positive MBC and is well tolerated. Combined chemoendocrine approaches should be further explored considering the low toxicity of the combination with meaningful TTP.

Willingness to pay to prevent chemotherapy induced nausea and vomiting among patients with breast, lung, or colorectal cancer.

OBJECTIVE: Understanding the value patients place on avoiding various aspects of chemotherapy induced nausea and vomiting (CINV) can help medical professionals assess whether current and emerging treatments are acceptable based on their costs and expected effects. Little is known, however, about the value patients place on avoiding various aspects of CINV. The current study helps fill this gap in the literature. METHODS: 301 patients completed a discrete-choice conjoint survey. Patients viewed 25 conjoint tasks, each containing two descriptions of CINV, and indicated which they preferred. The descriptions combined levels from eight CINV attributes (likelihood of nausea, duration of nausea, severity of nausea, likelihood of vomiting, duration of vomiting, severity of vomiting, need to seek treatment for dehydration, and out-of-pocket treatment costs). RESULTS: Cost contributed more to patient choices than any other single attribute. The combined effect of the likelihood, duration, and severity attributes for nausea, however, was a stronger driver of patient choices than cost, as was the combined effect of the likelihood, duration, and severity attributes for vomiting. The nausea attributes also were a stronger driver of patient choices than the vomiting attributes. Patients were willing to pay to avoid increases in all attributes, except likelihood of vomiting, where the result was not statistically different from zero. Willingness-to-pay varied by income, disease stage, Eastern Cooperative Oncology Group performance status, chemotherapy status, and whether patients worked while on chemotherapy. LIMITATIONS: Although the study used a convenience sample, data were collected from several geographically dispersed U.S. oncology clinics. CONCLUSIONS: Several antiemetics are now available at different price points. This study assesses the value patients place on their benefits and may be used to inform decisions about the management of CINV.

"Real world" treatment of metastatic renal cell carcinoma in a joint community-academic cohort: progression-free survival over three lines of therapy.

BACKGROUND: New targeted therapeutics approved for metastatic renal cell carcinoma (mRCC) offer multiple options in each line of therapy; however, there are few prospective data beyond the first-line settings, and overall comparative effectiveness data are limited. In the targeted therapy era, progression-free survival (PFS) has been the most common regulatory end point for demonstrating the benefit of new therapies. PATIENTS AND METHODS: Drawing on a joint community-academic retrospective mRCC registry, we analyzed all patients who had undergone at least 1 line of systemic therapy (N = 325) for PFS. Patients were grouped according to treatment choice (sorafenib, sunitinib, temsirolimus, everolimus, and "other") for up to 3 lines of therapy. PFS by treatment choice and line of therapy was evaluated using Kaplan-Meier and Cox regression analyses. RESULTS: PFS was longest in patients treated with sunitinib in the first and second lines of therapy. First-line PFS for sorafenib, sunitinib, temsirolimus, everolimus, and "other" was 6.9, 8.9, 4.2, not analyzed (too few patients), and 10.8 months, respectively. Second-line PFS was 4.6, 7.0, 3.2, 3.8, and 4.1 months, respectively. Third-line PFS was 4.5, 4.6, 9.9, 4.2, and 2.9, months, respectively. The risk of progression in patients treated with temsirolimus was about twice that of patients treated with sunitinib in the first and second lines of therapy. CONCLUSION: Patients treated with sunitinib had the longest PFS in the first and second lines of therapy. PFS from practice-based data appear consistent with trial-based expectations; however, practice variation was still evident.

Sorafenib or placebo with either gemcitabine or capecitabine in patients with HER-2-negative advanced breast cancer that progressed during or after bevacizumab.

PURPOSE: We assessed adding the multikinase inhibitor sorafenib to gemcitabine or capecitabine in patients with advanced breast cancer whose disease progressed during/after bevacizumab. EXPERIMENTAL DESIGN: This double-blind, randomized, placebo-controlled phase IIb study (ClinicalTrials.gov NCT00493636) enrolled patients with locally advanced or metastatic human epidermal growth factor receptor 2 (HER2)-negative breast cancer and prior bevacizumab treatment. Patients were randomized to chemotherapy with sorafenib (400 mg, twice daily) or matching placebo. Initially, chemotherapy was gemcitabine (1,000 mg/m(2) i.v., days 1, 8/21), but later, capecitabine (1,000 mg/m(2) orally twice daily, days 1-14/21) was allowed as an alternative. The primary endpoint was progression-free survival (PFS). RESULTS: One hundred and sixty patients were randomized. More patients received gemcitabine (82.5%) than capecitabine (17.5%). Sorafenib plus gemcitabine/capecitabine was associated with a statistically significant prolongation in PFS versus placebo plus gemcitabine/capecitabine [3.4 vs. 2.7 months; HR = 0.65; 95% confidence interval (CI): 0.45-0.95; P = 0.02], time to progression was increased (median, 3.6 vs. 2.7 months; HR = 0.64; 95% CI: 0.44-0.93; P = 0.02), and overall response rate was 19.8% versus 12.7% (P = 0.23). Median survival was 13.4 versus 11.4 months for sorafenib versus placebo (HR = 1.01; 95% CI: 0.71-1.44; P = 0.95). Addition of sorafenib versus placebo increased grade 3/4 hand-foot skin reaction (39% vs. 5%), stomatitis (10% vs. 0%), fatigue (18% vs. 9%), and dose reductions that were more frequent (51.9% vs. 7.8%). CONCLUSION: The addition of sorafenib to gemcitabine/capecitabine provided a clinically small but statistically significant PFS benefit in HER2-negative advanced breast cancer patients whose disease progressed during/after bevacizumab. Combination treatment was associated with manageable toxicities but frequently required dose reductions.

Phase II clinical trial of bevacizumab with albumin-bound paclitaxel in patients with recurrent, platinum-resistant primary epithelial ovarian or primary peritoneal carcinoma.

OBJECTIVE: We examined the safety and efficacy of combining bevacizumab with albumin-bound (ab-) paclitaxel to treat patients with recurrent, platinum-resistant primary epithelial ovarian or peritoneal carcinoma. METHODS: Patients had measurable disease per RECIST guidelines, progressing within 6 months after a prior course of platinum-based treatment. Patients received ab-paclitaxel 100mg/m(2) given by intravenous infusion over 30 min on days 1, 8, and 15 of a 28-day cycle with bevacizumab 10mg/kg given on days 1 and 15. RESULTS: Forty-eight patients with an average 1.8 prior lines of treatment participated. The overall response rate was 50% (24/48) (95% CI, 34.8% - 65.1%), with 4 complete and 20 partial responses. Fourteen patients (29%) had stable disease, whereas eight (17%) had progressive disease, and two (4%) were not evaluable. Patients received a median of 6 treatment cycles (range, 1 - 31 cycles). The median progression-free survival was 8.08 months (95% CI, 5.78 - 10.15 months); 6 month progression-free rate was 62.5% (95% CI, 47.8%-77.2%); median overall survival was 17.15 months (95% CI, 13.57 - 23.82 months). Grade 3-4 adverse events included gastrointestinal disorders (18.8%), neutropenia (8.3%), and hypertension (6.3%). CONCLUSIONS: Ab-paclitaxel with bevacizumab clearly demonstrates antitumor activity and manageable toxicity profile in patients with recurrent, platinum-resistant ovarian carcinoma. This regimen should be evaluated in a larger randomized trial.

The association of rash severity with overall survival: findings from patients receiving erlotinib for pancreatic cancer in the community setting.

OBJECTIVES: This retrospective study examined pancreatic cancer patients who received combination gemcitabine and erlotinib to determine if the association between rash and outcomes observed in clinical trials would be observed in 'real-world' community oncology settings. METHODS: Medical records from 10 community oncology practices were used to identify eligible patients. Rash severity was classified as High (moderate/severe) versus Low (absent/mild) based on medical record review. Kaplan-Meier analysis assessed progression-free survival (PFS) and overall survival (OS) by rash status from a landmark of 42 days after treatment initiation. Cox regression with time-varying covariates tested whether high-severity rash predicted longer OS and PFS. RESULTS: The High Severity group (n = 34) had longer median OS from the landmark than the Low Severity group (n = 134; 7.58 months vs 5.03 months, P = 0.0339). Cox regression analysis (n = 174) confirmed a reduced risk of death with High Rash Severity (hazard ratio [HR] = 0.67, P = 0.0389). Progression-free survival results showed a similar pattern (median PFS 2.37 months from landmark vs 2.04 months for High vs Low Severity groups, P = 0.0485). CONCLUSIONS: Results from this community sample were consistent with findings from randomized clinical trials, showing that longer OS is predicted by high-severity rash in erlotinib-treated pancreatic cancer patients.

Relationship between incidence of fracture and health-related quality-of-life in metastatic breast cancer patients with bone metastases.

OBJECTIVE: This retrospective observational study describes treatment patterns and longitudinal health-related quality-of-life (HRQoL) among metastatic breast cancer patients with bone metastasis from nine community oncology clinics. METHODS: For description of treatment patterns, patients were classified as treated if they started zoledronic acid within 60 days of diagnosis of bone metastasis, were considered untreated if they had not, and were considered unclassified if they died or experienced fracture before 60 days had elapsed. Medical record review provided demographic and disease characteristics as well as history of treatment. Patients completed Patient Care Monitor (PCM) assessments of patient reported outcomes during routine care for up to 2 years from the date of bone metastasis diagnosis. RESULTS: The overall rate of fracture in the sample was 17.4%. Of the 321 patients enrolled, 160 were treated as of 60 days after diagnosis of bone metastasis, 147 were untreated, and 14 were unclassified. Of the 147 untreated as of 60 days, 82 did eventually receive zoledronic acid. More than half of all patients treated with zoledronic acid delayed the start of treatment by more than 30 days after diagnosis of bone metastasis. Patients who had a fracture showed decreased mobility and increased pain and anxiety at fracture, with recovery taking ~16 months. LIMITATIONS: Key limitations included: convenience sample with information limited to medical record content, low rate of observed fractures possibly due to limited 2-year follow-up, and exclusion of non-zoledronic acid bisphosphonate use. CONCLUSIONS: Whereas the proportion of patients experiencing a fracture was small, the impact of fracture on HRQoL was significant and was more prominently seen to impact specific dimensions of HRQoL.

Symptom burden & quality of life among patients receiving second-line treatment of metastatic colorectal cancer.

BACKGROUND: Bevacizumab (B) and cetuximab (C) are both approved for use in the treatment of metastatic colorectal cancer (mCRC) in the second-line. We examined patient reported symptom burden during second-line treatment of mCRC. METHODS: Adult mCRC patients treated in the second-line setting with a regimen that included B, C, or chemotherapy only (O) and who had completed ≥ 1 Patient Care Monitor (PCM) surveys as part of routine clinical care were drawn from the ACORN Data Warehouse. Primary endpoints were rash, dry skin, itching, nail changes, nausea, vomiting, fatigue, burning in hands/feet, and diarrhea. Linear mixed models examined change in PCM scores across B, C and O (B = reference). RESULTS: 182 patients were enrolled (B: n = 106, C: n = 38, O: n = 38). Patients were 51% female, 67% Caucasian, with mean age of 62.0 (SD = 12.6). Groups did not differ on demographic or clinical characteristics. The most common second-line regimens were FOLFIRI ± B or C (23.1%) and FOLFOX ± B or C (22.5%). Results showed baseline scores to be strongly predictive of second-line symptoms across all PCM items (all p's < .0001 except for Rash, p = .0013). Controlling for baseline, patients on B tended to have more stable and less severe symptoms. Patients on C had more severe rash, dry skin, and itching and had nail change scores that worsened faster than did B patients. CONCLUSIONS: Patients receiving second-line treatment for mCRC with B report less symptom burden, especially dermatologic, compared to patients treated with C.

Hematologic outcomes and blood utilization in cancer patients with chemotherapy-induced anemia (CIA) pre- and post-national coverage determination (NCD): results from a multicenter chart review.

PURPOSE: In July 2007, the Centers for Medicare and Medicaid Services (CMS) limited coverage of erythropoiesis-stimulating agents (ESAs) in cancer patients with chemotherapy-induced anemia (CIA) through a National Coverage Determination (NCD). The primary objective of this study was to compare transfusion rates in patients with CIA with lung, breast, or colorectal cancer before and after the NCD. METHODS: Adult Medicare patients with CIA treated at 49 community oncology clinics were selected from two time periods based on clinics' NCD implementation date. Chart data were abstracted for 12 weeks post-CIA episode start, defined as hemoglobin (Hb) level <11 g/dL while receiving chemotherapy or within 60 days of the last chemotherapy dose. Multivariate analyses were used to calculate the odds of transfusion and to assess the units of blood transfused, controlling for differences in demographics, clinical history, and chemotherapy. RESULTS: Eight hundred pre-NCD and 994 post-NCD patients from 49 sites were selected. Of the patients, 56% used ESAs post-NCD vs. 88% pre-NCD (p < 0.0001). The duration of ESA use decreased in the post-NCD (32.1 days) vs. pre-NCD (48.4 days, p < 0.0001) group. The post-NCD group reported significantly lower Hb levels, higher odds of receiving a transfusion (odds ratio: 1.41, 95% CI 1.05-1.89, p = 0.0238) and increased blood utilization of 53% (units transfused: OR 1.53, 95% CI 1.15-2.04, p = 0.0034). CONCLUSIONS: Decreased frequency and duration of ESA administration were reported in the post-NCD vs. pre-NCD period. Findings were accompanied by a modest but statistically significant increase in transfusions and a decrease in Hb values.

Testing the reliability and validity of DSM-IV-TR and ICSD-2 insomnia diagnoses. Results of a multitrait-multimethod analysis.

CONTEXT: Distinctive diagnostic classification schemes for insomnia diagnoses are available, but the optimal insomnia nosology has yet to be determined. OBJECTIVES: To test the reliability and validity of insomnia diagnoses listed in the American Psychiatric Association's DSM-IV-TR and the International Classification of Sleep Disorders, second edition (ICSD-2). DESIGN: Multitrait-multimethod correlation design. SETTING: Two collaborating university medical centers, with recruitment from January 2004 to February 2009. PARTICIPANTS: A total of 352 adult volunteers (235 of whom were women) who met research diagnostic criteria for insomnia disorder. MAIN OUTCOME MEASURES: Goodness-of-fit ratings of 10 DSM-IV-TR and 37 ICSD-2 insomnia diagnoses for each patient. Ratings were provided by 3 clinician pairs who used distinctive assessment methods to derive diagnostic impressions. Correlations computed within and across clinician pairs were used to test reliability and validity of diagnoses. RESULTS: Findings suggested that the best-supported DSM-IV-TR insomnia categories were insomnia related to another mental disorder, insomnia due to a general medical condition, breathing-related sleep disorder, and circadian rhythm sleep disorder. The category of primary insomnia appeared to have marginal reliability and validity. The best-supported ICSD-2 categories were the insomnias due to a mental disorder and due to a medical condition, obstructive sleep apnea, restless legs syndrome, idiopathic insomnia, and circadian rhythm sleep disorder-delayed sleep phase type. Psychophysiological insomnia and inadequate sleep hygiene received much more variable support across sites, whereas the diagnosis of paradoxical insomnia was poorly supported. CONCLUSIONS: Both the DSM-IV-TR and ICSD-2 provide viable insomnia diagnoses, but findings support selected subtypes from each of the 2 nosologies. Nonetheless, findings regarding the frequently used DSM-IV-TR diagnosis of primary insomnia and its related ICSD-2 subtypes suggest that their poor reliability and validity are perhaps due to significant overlap with comorbid insomnia subtypes. Therefore, alternate diagnostic paradigms should be considered for insomnia classification.

Retrospective study of the effect of disease progression on patient reported outcomes in HER-2 negative metastatic breast cancer patients.

BACKGROUND: This retrospective study evaluated the impact of disease progression and of specific sites of metastasis on patient reported outcomes (PROs) that assess symptom burden and health related quality of life (HRQoL) in women with metastatic breast cancer (mBC). METHODS: HER-2 negative mBC patients (n = 102) were enrolled from 7 U.S. community oncology practices. Demographic, disease and treatment characteristics were abstracted from electronic medical records and linked to archived Patient Care Monitor (PCM) assessments. The PCM is a self-report measure of symptom burden and HRQoL administered as part of routine care in participating practices. Linear mixed models were used to examine change in PCM scores over time. RESULTS: Mean age was 57 years, with 72% of patients Caucasian, and 25% African American. Median time from mBC diagnosis to first disease progression was 8.8 months. Metastasis to bone (60%), lung (28%) and liver (26%) predominated at initial metastatic diagnosis. Results showed that PCM items assessing fatigue, physical pain and trouble sleeping were sensitive to either general effects of disease progression or to effects associated with specific sites of metastasis. Progression of disease was also associated with modest but significant worsening of General Physical Symptoms, Treatment Side Effects, Acute Distress and Impaired Performance index scores. In addition, there were marked detrimental effects of liver metastasis on Treatment Side Effects, and of brain metastasis on Acute Distress. CONCLUSIONS: Disease progression has a detrimental impact on cancer-related symptoms. Delaying disease progression may have a positive impact on patients' HRQoL.

Symptom Burden and Quality of Life in Patients with Follicular Lymphoma undergoing Maintenance Treatment with Rituximab Compared with Observation.

BACKGROUND: The impact on health related quality of life (HRQoL) of rituximab maintenance (R-M) versus observation (OBS) after induction for treatment of follicular lymphoma (FL) is unclear. METHODS: We reviewed the charts of 137 patients (53% female, 87% White, age 61.0 ± 12.4 years) who received either R-M (n = 53) or OBS (n = 84) after chemotherapy induction for newly diagnosed FL at community oncology practices within the US. Patients (65% with advanced disease; 48% with a high FLIPI score [3-5]) had completed ≥1 Patient Care Monitor HRQoL survey in the period following front-line therapy, and were excluded if they had progressed during front-line therapy. RESULTS: Linear mixed models showed that postinduction, most symptoms were stable, with patients on R-M reporting HRQoL that was equal to that reported by OBS patients. CONCLUSIONS: Among R-M patients, receipt of rituximab was associated with improved psychological symptoms.

Examining maladaptive beliefs about sleep across insomnia patient groups.

OBJECTIVES: Unhelpful beliefs about sleep have been linked to insomnia, and increasing one's cognitive flexibility about sleep has been linked to posttreatment sleep improvement. This study evaluated whether levels of such beliefs differ across insomnia groups and whether there are particular beliefs that differ for specific insomnia subtypes. METHODS: Participants (N=1384) were people with insomnia and good sleepers ranging from 18 to 89 years old (mean=42.6; S.D.=19.4). Data from previous studies at five insomnia clinical sites were pooled to examine responses on the Dysfunctional Beliefs and Attitudes about Sleep Scale (DBAS) across differing insomnia groups. RESULTS: Group analyses revealed that those from community-based insomnia clinics and those who are hypnotic-dependent generally had the highest levels of unhelpful sleep-related beliefs. With the exception of beliefs about sleep needs (wherein only community sleep clinic patients had high scores relative to good sleepers), all insomnia groups had higher scores on the 16-item DBAS (DBAS-16) than good sleepers. A validity analysis suggested that a DBAS-16 index score of >3.8 represented the level of unhelpful beliefs associated with clinically significant insomnia, although a slightly lower cutoff may be useful for identifying an unhelpful degree of sleep-related beliefs in highly screened primary-insomnia-only and medical patient groups. CONCLUSIONS: This study offers descriptive data for the use of DBAS-16 across insomnia subgroups, which will help the user understand what degree of maladaptive sleep beliefs is most strongly associated with clinically significant levels of insomnia. Results also may have implications for cognitive targeting during treatment for particular insomnia groups.

Cognitive behavioral therapy for insomnia improves sleep and decreases pain in older adults with co-morbid insomnia and osteoarthritis.

STUDY OBJECTIVES: Osteoarthritis pain affects more than half of all older adults, many of whom experience co-morbid sleep disturbance. Pain initiates and exacerbates sleep disturbance, whereas disturbed sleep maintains and exacerbates pain, which implies that improving the sleep of patients with osteoarthritis may also reduce their pain. We examined this possibility in a secondary analysis of a previously published randomized controlled trial of cognitive behavioral therapy for insomnia (CBT-I) in patients with osteoarthritis and co-morbid insomnia. METHODS: Twenty-three patients (mean age 69.2 years) were randomly assigned to CBT-I and 28 patients (mean age 66.5 years) to an attention control. Neither directly addressed pain management. Twelve subjects crossed over to CBT-I after control treatment. Sleep and pain were assessed by self-report at baseline, after treatment, and (for CBT-I only) at 1-year follow-up. RESULTS: CBT-I subjects reported significantly improved sleep and significantly reduced pain after treatment. Control subjects reported no significant improvements. One-year follow-up found maintenance of improved sleep and reduced pain for both the CBT-I group alone and among subjects who crossed over from control to CBT-I. CONCLUSIONS: CBT-I but not an attention control, without directly addressing pain control, improved both immediate and long-term self-reported sleep and pain in older patients with osteoarthritis and comorbid insomnia. These results are unique in suggesting the long-term durability of CBT-I effects for co-morbid insomnia. They also indicate that improving sleep, per se, in patients with osteoarthritis may result in decreased pain. Techniques to improve sleep may be useful additions to pain management programs in osteoarthritis, and possibly other chronic pain conditions as well.

The relation of trouble sleeping, depressed mood, pain, and fatigue in patients with cancer.

STUDY OBJECTIVES: To evaluate the relation among several symptoms that occur commonly in cancer patients: trouble sleeping, fatigue/sleepiness, depressed mood, and pain in a large cohort of cancer patients undergoing treatment in a community oncology practice. METHODS: Demographic, clinical, and patient reported outcomes data from 11,445 cancer patients undergoing treatment in a large community oncology practice were analyzed using structural equation modeling. The data were split so that a model was constructed using half of the patients; this model was then cross-validated on the remaining patients. RESULTS: Fatigue was best represented as a latent variable, and significant direct effects were found for trouble sleeping, depressed mood, and pain. Also, there were significant indirect effects of these variables on fatigue. The effect of depressed mood on fatigue and pain was mediated by trouble sleeping, and the effect of trouble sleeping on fatigue was mediated by pain. CONCLUSIONS: These results predict that interventions aimed at treatment of trouble sleeping, depressed mood, and pain will improve fatigue in patients with cancer. Further, these data predict that treatment of trouble sleeping will improve pain management in this population.
