Effect of Brain Metastasis on Patient-Reported Outcomes in Advanced NSCLC Treated in Real-World Community Oncology Settings.

INTRODUCTION: Health-related quality of life (HRQOL) in advanced non-small-cell lung cancer (NSCLC) might be affected by the presence of brain metastasis (BM). We report findings from a prospective observational study that examined HRQOL in patients newly diagnosed with advanced NSCLC, with or without baseline BM, through 1 year of follow-up. PATIENTS AND METHODS: Patients starting first-line treatment of stage IIIB/IV NSCLC were prospectively enrolled and consented at 34 US-based community oncology practices. Data on patient-reported outcomes (PROs) were collected once per cycle during treatment, and at each visit after discontinuation. PROs included the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (QLQ-C30) and Lung Cancer Module (QLQ-LC13), the Lung Cancer Module of the M.D. Anderson Symptom Inventory (MDASI-LC), and the Rotterdam Activity Level Scale (RALS). Linear mixed models were used to examine the effect of baseline BM, including differences in change over time. RESULTS: One hundred forty-five patients provided follow-up PRO data, comprising 1100 individual surveys and 32 PRO end points. The patient group was 58.6% (n = 85) male, and 86.2% (n = 125) Caucasian. Patients with baseline BM were younger (61.3 vs. 65.8 years; P = .040) with more concurrent radiotherapy (59.4% [n = 19] vs. 15.9% [n = 18]; P < .0001). Results showed minimal differences in baseline HRQOL. Of the 20 measures that showed significant group differences in HRQOL over time, 18 showed greater deterioration for patients with baseline BM. These 18 measures included all QLQ-C30 composite measures except Global Health Status, all MDASI-LC measures, and the RALS (all P < .05). For these measures, the average 1-year deterioration in patients with baseline BM was 19.4%. CONCLUSION: Newly diagnosed advanced NSCLC patients with baseline BM experienced a significantly faster and clinically meaningful deterioration in PRO-based HRQOL compared with those without baseline BM.

Effectiveness outcomes and health related quality of life impact of disease progression in patients with advanced nonsquamous NSCLC treated in real-world community oncology settings: results from a prospective medical record registry study.

BACKGROUND: Treatment options for advanced nonsquamous non-small cell lung cancer (NSCLC) in the first line include platinum-based doublet therapy with or without bevacizumab. This study examined efficacy outcomes and patient reported outcomes (PROs) in a community oncology patient sample. METHODS: Advanced nonsquamous NSCLC patients from 34 U.S. community oncology practices treated in first line with bevacizumab regimens (A platinum doublet; gemcitabine doublet; pemetrexed with platinum) or non-bevacizumab regimens (B platinum doublet; gemcitabine doublet; C pemetrexed with platinum) were recruited for this prospective study. Patient characteristics and clinical outcomes were accessed from routine care records. Three validated and widely used PRO measures of health related quality of life (HRQOL) and symptom burden were collected prospectively at each visit and up to one-year follow-up. Effectiveness outcomes were progression free survival (PFS) and overall survival (OS) assessed by Kaplan-Meier and Cox regression methods. PROs were analyzed with linear mixed model regression to examine changes over time, and the effect of disease progression. RESULTS: Of 147 patients in the study, 145 provided PRO data. Patients in treatment groups were: A (n = 66, 44.9%); B (n = 25, 17.0%); C (n = 56, 38.1%). A was associated with significantly longer OS than B (HR = 0.341, p = 0.0012), and significantly longer than C (HR = 0.602, p = 0.0354). PFS results were similar. Irrespective of regimen group and on 12/32 measures, patients showed significant and clinically meaningful worsening of symptoms and HRQOL at disease progression. After disease progression, the pattern of symptom and HRQOL change showed continued worsening. CONCLUSIONS: Bevacizumab-containing regimens were associated with longer PFS and OS compared with non-bevacizumab regimens. PRO measures show disease progression is associated with worsening HRQOL. Delaying disease progression can sustain better HRQL and reduce symptom burden.

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 Health Resource Utilization Among Patients Diagnosed With Early Stage Resected Non-Small Cell Lung Cancer at US Community Oncology Practices.

UNLABELLED: Data on adjuvant therapy in resected non-small cell lung cancer (NSCLC) in routine practice are lacking in the United States. This retrospective observational database study included 609 community oncology patients with resected stage IB to IIIA NSCLC. Use of adjuvant therapy was 39.1% at disease stage IB and 64.9% to 68.2% at stage II to IIIA. The most common regimen at all stages was carboplatin and paclitaxel. BACKGROUND: Platin-based adjuvant chemotherapy has extended survival in clinical trials in patients with completely resected non-small cell lung cancer (NSCLC). There are few data on the use of adjuvant therapy in community-based clinical practice in the United States. MATERIALS AND METHODS: This was a retrospective observational study using electronic medical record and billing data collected during routine care at US community oncology sites in the Vector Oncology Data Warehouse between January 2007 and January 2014. Patients aged ≥ 18 years with a primary diagnosis of stage IB to IIIA NSCLC were eligible if they had undergone surgical resection. Treatment patterns, health care resource use, and cost were recorded, stratified by stage at diagnosis. RESULTS: The study included 609 patients (mean age, 64.8 years, 52.9% male), of whom 215 had stage IB disease, 130 stage IIA/II, 110 stage IIB, and 154 stage IIIA. Adjuvant systemic therapy after resection was provided to 345 (56.7%) of 609 patients, with lower use in patients with stage IB disease (39.1%) than stage II to IIIA disease (64.9-68.2%) (P < .0001). The most common adjuvant regimen at all stages was the combination of carboplatin and paclitaxel. There were no statistically significant differences in office visits or incidence of hospitalization by disease stage. During adjuvant treatment, the total monthly median cost per patient was $17,389.75 (interquartile range, $8,815.61 to $23,360.85). CONCLUSION: Adjuvant systemic therapy was used in some patients with stage IB NSCLC and in the majority of patients with stage IIA to IIIA disease. There were few differences in regimen or health care resource use by disease stage.

Phase 1b study of safety, tolerability and efficacy of R1507, a monoclonal antibody to IGF-1R in combination with multiple standard oncology regimens in patients with advanced solid malignancies.

BACKGROUND: R1507 is a human IgG1 Mab that binds to the insulin-like growth factor-1 receptor (IGF-1R) and inhibits IGF-1- or IGF-2-mediated anchorage-independent growth of malignant cells. A phase 1b study evaluated the safety, tolerability and efficacy of R1507 in combination with multiple standard oncology regimens. METHODS: R1507 (3, 5, 9, 10 and 16 mg/kg IV, Q2 W or Q3 W) was added to six treatment regimens: gemcitabine + erlotinib (GE); paclitaxel + bevacizumab (PB); carboplatin + etoposide (CE); mFOLFOX6 + bevacizumab (FB); capecitabine + trastuzumab (CT); and sorafenib (S). If tolerable, R1507 dose was escalated utilizing a 3 + 3 + 6 and a 3 + 9 design. RESULTS: A total of 104 patients enrolled into regimens 1-6: 93 % were non-recent diagnoses. Eighteen withdrew for safety [one death, 17 adverse events (AEs)]. A total of 1,337 AEs any grade, across regimens and doses were nausea, vomiting and diarrhea. A total of 123 had grade ≥3 AEs (n = 28 dose level 1; n = 95 dose level 1) and in 60 patients were myelosuppression, fatigue and mucosal inflammation. ORR (PR plus SD) of evaluable patients across six regimens was 36 % with five PRs: regimens PB (non-small cell lung cancer, nasopharyngeal cancer), CE (melanoma), FB (colon cancer) and S (GIST). The GIST pt (>4 prior therapies) had a PR for 3 years. Three patients (breast cancer, melanoma and adenoid cystic carcinoma) were on study for >1 year; 76 % of patients had SD or better for 4 months. CONCLUSIONS: R1507 added to six standard oncology regimens was well tolerated with an ORR of 36 %.

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.

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.

Positive illusions in marital relationships: a 13-year longitudinal study.

This study examined the long-term consequences of idealization in marriage, using both daily diary and questionnaire data collected from a sample of 168 newlywed couples who participated in a 4-wave, 13-year longitudinal study of marriage. Idealization was operationalized as the tendency for people to perceive their partner as more agreeable than would be expected based on their reports of their partner's agreeable and disagreeable behaviors. Spouses who idealized one another were more in love with each other as newlyweds. Longitudinal analyses suggested that spouses were less likely to suffer declines in love when they idealized one another as newlyweds. Newlywed levels of idealization did not predict divorce.

Trust and partner-enhancing attributions in close relationships.

A cross-lagged panel design was used to examine the links between trust and attributional processes in a sample of 75 married couples throughout a period of 2 years. During the first phase of the study, participants completed a measure of marital trust, engaged in a laboratory problem-solving discussion of a recurrent conflict-related issue, and then rated their partner's behavior and motives. Approximately 2 years later, 54 couples were again contacted and measures of trust were obtained. Forty of these couples also viewed a videotape of their laboratory problem-solving discussion from 2 years previously and rated their partner's behavior and motives. Results suggested a reciprocal causal pattern by which partner-enhancing attributions predict changes in trust and trust predicts changes in partner-enhancing attributions.
