TBCRC 057: Survey about willingness to participate in cancer clinical trials during the pandemic

BACKGROUND

Breast cancer patients experienced heightened anxiety during the pandemic. Also, modifications to clinical trial activities allowing for virtual platforms, local assessments, and greater flexibility were introduced to facilitate participation. We sought to evaluate the association between pandemic-related anxiety and willingness to participate in trials and how pandemic-era modifications to trial activities affect the decision to participate.

METHODS

We conducted an online survey from August to September, 2021 of patients with breast cancer assessing pandemic-related anxiety; clinical trials knowledge and attitudes; willingness to participate during and before the pandemic; and how each modification affects the decision to participate. Fisher's exact tests evaluated differences in proportions and two-sample t-tests evaluated differences in means. The association of pandemic-related anxiety with a decline in willingness to participate during compared to prior to the pandemic was modeled using logistic regression.

RESULTS

Among 385 respondents who completed the survey, 81% reported moderate-severe pandemic-related anxiety. Mean willingness to participate in a trial was lower during the pandemic than prior [2.97 (SD 1.17) vs. 3.10 (SD 1.09), (p < 0.001)]. Severe anxiety was associated with higher odds of diminished willingness to participate during the pandemic compared to prior (OR 5.07). Each of the modifications, with the exception of opting out of research-only blood tests, were endorsed by >50% of respondents as strategies that would increase their likelihood of deciding to participate.

CONCLUSIONS

While pandemic-related anxiety was associated with diminished willingness to participate in trials, the leading reasons for reluctance to consider trial participation were unrelated to the pandemic but included worries about not getting the best treatment, side effects, and delaying care. Patients view trial modifications favorably, supporting continuation of these modifications, as endorsed by the National Cancer Institute and others.

Iterative Patient Testing of a Stimuli-Responsive Swallowing Activity Sensor to Promote Extended User Engagement During the First Year After Radiation: Multiphase Remote and In-Person Observational Cohort Study

BACKGROUND

Frequent sensor-assisted monitoring of changes in swallowing function may help improve detection of radiation-associated dysphagia before it becomes permanent. While our group has prototyped an epidermal strain/surface electromyography sensor that can detect minute changes in swallowing muscle movement, it is unknown whether patients with head and neck cancer would be willing to wear such a device at home after radiation for several months.

OBJECTIVE

We iteratively assessed patients' design preferences and perceived barriers to long-term use of the prototype sensor.

METHODS

In study 1 (questionnaire only), survivors of pharyngeal cancer who were 3-5 years post treatment and part of a larger prospective study were asked their design preferences for a hypothetical throat sensor and rated their willingness to use the sensor at home during the first year after radiation. In studies 2 and 3 (iterative user testing), patients with and survivors of head and neck cancer attending visits at MD Anderson's Head and Neck Cancer Center were recruited for two rounds of on-throat testing with prototype sensors while completing a series of swallowing tasks. Afterward, participants were asked about their willingness to use the sensor during the first year post radiation. In study 2, patients also rated the sensor's ease of use and comfort, whereas in study 3, preferences were elicited regarding haptic feedback.

RESULTS

The majority of respondents in study 1 (116/138, 84%) were willing to wear the sensor 9 months after radiation, and participant willingness rates were similar in studies 2 (10/14, 71.4%) and 3 (12/14, 85.7%). The most prevalent reasons for participants' unwillingness to wear the sensor were 9 months being excessive, unwanted increase in responsibility, and feeling self-conscious. Across all three studies, the sensor's ability to detect developing dysphagia increased willingness the most compared to its appearance and ability to increase adherence to preventive speech pathology exercises. Direct haptic signaling was also rated highly, especially to indicate correct sensor placement and swallowing exercise performance.

CONCLUSIONS

Patients and survivors were receptive to the idea of wearing a personalized risk sensor for an extended period during the first year after radiation, although this may have been limited to well-educated non-Hispanic participants. A significant minority of patients expressed concern with various aspects of the sensor's burden and its appearance.

Social media use is associated with higher levels of anxiety and depression in patients with neuroendocrine carcinoma of the cervix: A NeCTuR study

OBJECTIVE

Neuroendocrine cervical carcinoma (NECC) is rare. Educational resources are limited for NECC patients, leading many to seek information online through patient-led social networks. We sought to characterize the relationships between anxiety and depression levels and social media use among NECC patients.

METHODS

Seven surveys assessing social media use, anxiety, and depression were distributed to living NECC patients enrolled in our NECC registry. The primary outcomes were associations between Social Network Time Use Scale (SONTUS) global score and Generalized Anxiety Disorder (GAD-7) and Center for Epidemiologic Studies Depression Scale (CESD) total scores.

RESULTS

Eighty-eight patients enrolled; 81 who completed at least 1 survey were included. Ninety-seven percent (70/72) of patients completing SONTUS were low-to-average social media users. Seventy-four percent (53/72) of patients visited a patient-led NECC support-group page on Facebook within the past 4 weeks, and of those, 79% (42/53) reported receiving useful information. Among the patients who did not visit the page, 47% (9/19) reported that the page elicited anxiety and/or sadness. The mean GAD-7 and CES-D scores for the entire cohort were 7.3 and 18.1, respectively. The Spearman correlations between social media use and these scores were significant (GAD-7: 0.23 [p = 0.05]; CESD: 0.25 [p = 0.04]). The estimated odds ratios for moderate/severe anxiety and depression as a function of SONTUS global score were 1.26 (95% CI 1.03-1.55; p = 0.03) and 1.23 (95% CI 1.01-1.49; p = 0.04), respectively.

CONCLUSIONS

NECC patients demonstrated low-to-average social media use and relatively high anxiety and depression. Increased social media use was associated with elevated anxiety and depression.

The effect of modifications to clinical trial activities implemented during the COVID-19 pandemic on willingness to participate in clinical trials: The TBCRC 057 survey

97

Background: In order to maintain safety, clinical trial activities have been modified during the COVID-19 pandemic. As part of the TBCRC 057 survey, we assessed how pandemic-related modifications to trial activities affect breast cancer patients’ willingness to participate in clinical trials. Methods: US residents with breast cancer were eligible to complete the online survey 8/6/21 – 9/30/21. Respondents rated whether each of 11 modifications to clinical trial activities would affect their decision to participate in a trial during or after the pandemic. Items evaluated modifications that involved changing the location of trial activities to closer to home, switching trial activities to telemedicine and making the trial schedule more flexible and convenient. Response options were “much less likely to participate”, “somewhat less likely to participate”, “would not affect my decision whether or not to participate”, “somewhat more likely to participate” and “much more likely to participate”. Current trial participants were asked to consider how modifications would affect their decision to participate in another trial. Results are reported descriptively. Results: Among 385 respondents, median age was 52 (range 25-85), 88.6% were non-Hispanic White, 52.5% had metastatic disease, 93% were receiving active treatment, 48.6% received care at an academic center and 9.6% were current trial participants. Changing location of trial activities was viewed favorably, with 70.2%, 64.6% and 54.1% of respondents indicating they would be much or somewhat more likely to participate if they could complete trial blood tests, x-ray tests or doctor visits closer to home, respectively. Similarly, the option to complete trial activities electronically was viewed favorably, with 59.6%, 58.6% and 60.9% of respondents indicating they would be much or somewhat more likely to participate if they could complete trial doctor visits, consent and questionnaires via telemedicine, respectively. With regard to modifications to make the trial schedule more flexible and convenient, respondent feedback was also favorable. 71.4%, 67.7% and 82.4% of respondents indicated that requiring study site visits no more than once per 3 weeks, widening windows for trial activities and offering home delivery of oral study medications, respectively, would make them much or somewhat more likely to participate. Finally, 30.4% and 51.7% indicated that the flexibility to opt-out of research-only blood tests and biopsies, respectively, would make them much or somewhat more likely to participate. Conclusions: Patients view modifications to trial activities implemented during the pandemic favorably. Trials should be flexible and the option to conduct study activities close to home or electronically when possible should be maintained during the pandemic and beyond.

Network Modeling of Complex Time-Dependent Changes in Patient Adherence to Adjuvant Endocrine Treatment in ER+ Breast Cancer

Early patient discontinuation from adjuvant endocrine treatment (ET) is multifactorial and complex: Patients must adapt to various challenges and make the best decisions they can within changing contexts over time. Predictive models are needed that can account for the changing influence of multiple factors over time as well as decisional uncertainty due to incomplete data. AtlasTi8 analyses of longitudinal interview data from 82 estrogen receptor-positive (ER+) breast cancer patients generated a model conceptualizing patient-, patient-provider relationship, and treatment-related influences on early discontinuation. Prospective self-report data from validated psychometric measures were discretized and constrained into a decisional logic network to refine and validate the conceptual model. Minimal intervention set (MIS) optimization identified parsimonious intervention strategies that reversed discontinuation paths back to adherence. Logic network simulation produced 96 candidate decisional models which accounted for 75% of the coordinated changes in the 16 network nodes over time. Collectively the models supported 15 persistent end-states, all discontinued. The 15 end-states were characterized by median levels of general anxiety and low levels of perceived recurrence risk, quality of life (QoL) and ET side effects. MIS optimization identified 3 effective interventions: reducing general anxiety, reinforcing pill-taking routines, and increasing trust in healthcare providers. Increasing health literacy also improved adherence for patients without a college degree. Given complex regulatory networks’ intractability to end-state identification, the predictive models performed reasonably well in identifying specific discontinuation profiles and potentially effective interventions.

Factors associated with adherence to remote patient monitoring for early detection of dehydration risk during radiation treatment for head and neck cancer

6076

Background: Remote patient monitoring (RPM) may improve the early detection and mitigation of cancer treatment-related complications, health-related outcomes and quality of life. RPM’s success may depend, in part, on patients’ adherence to remote monitoring protocols. However, factors that influence adherence to RPM are largely unknown. Daily blood pressure/pulse (BP/P), weight, and electronic patient-reported outcomes (ePROs) were monitored remotely in head and neck cancer (HNC) patients undergoing radiation treatment (RT) to identify dehydration risk. We evaluated potential factors associated with RPM adherence. Methods: During RT (average 6 to 7 weeks), participants were asked to take daily (Monday-Friday) measures of BP/P and weight using Bluetooth-enabled devices and to complete daily ePROs using a mobile tablet application (app). Data were provided to their physicians for daily review. The MD Anderson Symptom Inventory-Head and Neck (MDASI-HN) was completed at baseline and end of RT, and 6-8 weeks post-RT completion. The Patient Activation Measure (PAM) was completed at baseline and 6-8 weeks post-RT completion. A device usability survey measuring perceived usefulness of RPM was completed at the end of RT. Adherence to daily monitoring was recorded objectively. Longitudinal analyses compared the relationship between demographic, clinical, and PRO data and monitoring adherence. Results: Participants (n = 169) were 80% male, 87% White, and 91% married. Overall adherence to monitoring BP/P, weight, and ePROs was 83%, 82% and 74%, respectively. Greater HN-specific symptom severity and interference was associated with decreased adherence to daily monitoring of BP/P, weight, and ePROs (P< 0.021). Higher PAM scores were associated with higher adherence to daily monitoring of BP/P only (p = 0.006). Participants reported modest levels of perceived usefulness of RPM across four categories: symptom management, early problem detection, illness monitoring by healthcare provider, and feeling of security during RT. Only a single item indicating perceived feeling of security was associated with greater adherence to daily monitoring of blood pressure/pulse (p = 0.032) and weight (p = 0.007). Conclusions: A benefit of frequent RPM may be early detection and mitigation of symptoms during RT for HNC, however, increasing symptom burden experienced during treatment may interfere with adherence to daily monitoring. Better adherence may be attributed to patients perceiving a sense of security from daily monitoring and may suggest a potentially important value that patients gain from RPM. Understanding factors that impact patient adherence to RPM may help improve acceptability and clinical utility of RPM in oncology. Clinical trial information: NCT02253238.

TBCRC 057: An online survey about anxiety and willingness to participate in breast cancer clinical trials during the COVID-19 pandemic

1564

Background: Enrollment in clinical trials has declined during the COVID-19 pandemic. Simultaneously, breast cancer patients have reported heightened anxiety. We assessed whether breast cancer patients’ anxiety about the pandemic affects their willingness to participate in trials. Methods: English or Spanish-speaking US residents with breast cancer were eligible to complete the online REDCap survey 8/6/21 – 9/30/21. Respondents rated their anxiety about the pandemic on an 11-point scale from 0 (no anxiety) to 10 (worst anxiety possible). Anxiety scores were categorized as no/mild (0-3), moderate (4-6) or severe (7-10). Knowledge about trials was assessed with 11 true/false items and attitudes toward trials with the Attitudes Toward Cancer Trials Scales - Cancer Treatment Subscale (ATCTS-CTS). Respondents rated their willingness to participate in a breast cancer clinical trial before and during the pandemic on 5-point scales from 0 (not at all willing) to 4 (definitely willing). Trial participants were considered “definitely willing.” Change in willingness to participate in trials during the pandemic compared to prior was defined as a binary outcome, "less willing" vs "no less willing." Means were compared via t-test and mean difference was tested via paired t-test. Multivariable logistic regression was used to model the association of anxiety and other factors with being less willing to participate in trials during compared to prior to the pandemic. Results: Among 385 respondents, median age was 52 (range 25-85), 271 (70%) were non-Hispanic White and 202 (53%) had metastatic disease. 154 (40%) received care at academic centers and 37 (10%) were current trial participants. Most rated their anxiety as moderate (43%) or severe (38%). Mean willingness to participate in a trial was lower during compared to prior to the pandemic (2.97 vs 3.10; p < 0.0001). Fifty (13%) respondents were less willing to participate in a trial during the pandemic compared to prior. After controlling for covariates, those with severe anxiety had 5.07 times odds of being less willing to participate during the pandemic compared to prior than those with no/mild anxiety (p = 0.01). For every 1-point increase in ATCTS-CTS score (indicating better attitude toward trials) there was a 3% decrease in the odds of being less willing to participate during the pandemic (p = 0.006). For every 1-point increase in the clinical trials knowledge score (indicating more knowledge) there was a 15% decrease in the odds of being less willing to participate during the pandemic (p = 0.02). Conclusions: Pandemic-related anxiety is common in breast cancer patients and is associated with being less willing to participate in trials during the pandemic compared to prior. Education about trials, including safety modifications implemented during the pandemic, may mitigate anxiety and improve willingness to participate.

Feasibility of Mobile and Sensor Technology for Remote Monitoring in Cancer Care and Prevention

Objectives. Remote monitoring (RM) of health-related outcomes may optimize cancer care and prevention outside of clinic settings. CYCORE is a software-based system for collection and analyses of sensor and mobile data. We evaluated CYCORE's feasibility in studies assessing: (1) physical functioning in colorectal cancer (CRC) patients; (2) swallowing exercise adherence in head and neck cancer (HNC) patients during radiation therapy; and (3) tobacco use in cancer survivors post-tobacco treatment (TTP). Methods. Participants completed RM: for CRC, blood pressure, activity, GPS; for HNC, video of swallowing exercises; for TTP, expired carbon monoxide. Patient-reported outcomes were assessed daily. Results. For CRC, HNC and TTP, respectively, 50, 37, and 50 participants achieved 96%, 84%, 96% completion rates. Also, 91-100% rated ease and self-efficacy as highly favorable, 72-100% gave equivalent ratings for overall satisfaction, 72-93% had low/no data privacy concerns. Conclusion. RM was highly feasible and acceptable for patients across diverse use cases.

Attributions of survival and methods of coping of long-term ovarian cancer survivors: a qualitative study

Background

Only 8–23% of advanced epithelial ovarian cancer patients survive for 10 years or longer. Given the need for targeted interventions to improve survival, we interviewed this relatively rare survivor population to gain personalized insights into the reasons for their survival. The aim of this study was to characterize subjective attributions of survival and specific coping mechanisms long-term survivors of ovarian cancer.

Methods

Twenty-two semi-structured, qualitative interviews assessing survival attributions and coping strategies were conducted from April to November 2014. Data were analyzed in a multistep process using ATLAS.ti.8: codes were identified during review of the transcripts and refined with literature review; the frequency of codes and code co-occurrence was calculated, and codes were grouped into themes. Resulting themes were checked by a national leader of an ovarian cancer advocacy organization and compared against available literature.

Results

Thematic analysis found that participants credited their long-term survival to a variety of factors including medical, social, religious/spiritual, and lifestyle/personal characteristics. Some participants rejected these same attributions, concluding that the reason for survival was due to luck or unknowable. Several of Carver et al.’s theoretical dimensions of coping were evident in our sample: planning, positive reinterpretation, social support, religion and acceptance whereas three relatively new strategies were uncovered: conserving emotional energy, value-based activity coping, and self-care.

Conclusions

Long-term survivors’ perspectives were largely consistent with those of newly diagnosed ovarian cancer patients and ovarian cancer survivors of shorter duration. However, the long-term survivors were also willing to reject conventional attributions for survival and recognized the importance of disciplined self-preservational coping strategies.

Active Living After Cancer: Adaptation and evaluation of a community-based physical activity program for minority and medically underserved breast cancer survivors

Background

An expanding body of research documents the benefits of physical activity for cancer survivors' physical functioning and quality of life, but few successful models provide community‐based physical activity programs to cancer survivors. This report presents an evaluation of Active Living After Cancer, an evidence‐based physical activity program for breast cancer survivors, adapted for community delivery to minority and medically underserved survivors.

Methods

Survivors were recruited from health care and community settings. The program consisted of 12 weekly group sessions providing training in cognitive and behavioral skills for behavior change, brief physical activity, and cancer survivorship‐related content. At the baseline and follow‐up, participants completed assessments of their physical activity, quality of life, and physical functioning (6‐minute walk and 30‐second sit‐to‐stand test). At follow‐up, they also completed questionnaires to measure program content mastery and satisfaction.

Results

The outcome analysis included 127 participants. Physical activity and quality of life (mental and physical) improved from the baseline to follow‐up (all P < .01). Physical functioning improved, with increases in sit‐to‐stand repetitions (mean, 12.5 at the baseline vs 14.9 at the follow‐up; P < .01) and 6‐minute walk distances (mean, 428 m at the baseline vs 470 m at the follow‐up; P < .01).

Conclusions

The results highlight the effectiveness of an evidence‐based program adapted for community‐based delivery to minority and medically underserved breast cancer survivors. The program could be delivered to improve outcomes in diverse survivor populations.

Lay Summary

Physical activity in breast cancer survivors is related to better quality of life and longer cancer‐free survival. However, there are few community‐based programs to help breast cancer survivors to become more physically active.

The Active Living After Cancer program was adapted from an evidence‐based program and delivered in community‐based settings to minority and medically underserved breast cancer survivors. It consisted of 12 weekly group sessions in which participants learned skills to increase their physical activity.

The program participants increased their physical activity and improved their mental and physical well‐being and physical functioning.

The Active Living After Cancer Program has been adapted from an evidence‐based program and implemented in the community for minority and medically underserved breast cancer survivors. Participants increase their physical activity and improve their quality of life and physical functioning.

Simulating Time-Dependent Patterns of Nonadherence by Patients With Breast Cancer to Adjuvant Oral Endocrine Therapy

PURPOSE

Nearly 40% of patients with breast cancer discontinue their adjuvant oral endocrine treatment (ET). We measured discontinuation rates of ET at a comprehensive cancer center. We then used an iterative approach to model patterns of determinants associated with discontinuation of ET.

METHODS

Patients with nonmetastatic breast cancer receiving active adjuvant ET were approached by nurse practitioners to complete an anonymous survey at one time point. We simulated a prospective model by iteratively regressing adverse effects onto adherence status across windowed time periods of 2 to 3 consecutive years, bootstrapping the smaller group of nonadherent patients and subsampling the larger adherent group.

RESULTS

From February to April 2013, 216 participants were enrolled in the study. Forty patients (18.5%) reported that they had discontinued ET during the first 5 years of ET, and an additional four patients (1.9%) missed > 20% of their doses. Using two-sided significance tests, simulations showed that all 13 ET adverse effects and reasons for discontinuation were significantly related to discontinuation at some time point during ET. Worry about ET cost (odds ratio [OR], 1.79), emotional distress (OR, 1.72), and bone and joint pain (OR, 1.69) were the three most impactful reasons for discontinuation, with varying patterns of influence over time.

CONCLUSION

These analyses provide preliminary evidence that there are varying patterns of discontinuation of ET. Although some reasons for discontinuation exerted a steady influence over the 6-year ET trajectory (ie, bone and joint pain), other reasons, such as cost, cognitive complaints, and general dislike of pills, became more important in the later years of ET.

Patient Health Questionnaire-9 scores do not accurately estimate depression prevalence: individual participant data meta-analysis

OBJECTIVES

Depression symptom questionnaires are not for diagnostic classification. Patient Health Questionnaire-9 (PHQ-9) scores ≥10 are nonetheless often used to estimate depression prevalence. We compared PHQ-9 ≥10 prevalence to Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (SCID) major depression prevalence and assessed whether an alternative PHQ-9 cutoff could more accurately estimate prevalence.

STUDY DESIGN AND SETTING

Individual participant data meta-analysis of datasets comparing PHQ-9 scores to SCID major depression status.

RESULTS

A total of 9,242 participants (1,389 SCID major depression cases) from 44 primary studies were included. Pooled PHQ-9 ≥10 prevalence was 24.6% (95% confidence interval [CI]: 20.8%, 28.9%); pooled SCID major depression prevalence was 12.1% (95% CI: 9.6%, 15.2%); and pooled difference was 11.9% (95% CI: 9.3%, 14.6%). The mean study-level PHQ-9 ≥10 to SCID-based prevalence ratio was 2.5 times. PHQ-9 ≥14 and the PHQ-9 diagnostic algorithm provided prevalence closest to SCID major depression prevalence, but study-level prevalence differed from SCID-based prevalence by an average absolute difference of 4.8% for PHQ-9 ≥14 (95% prediction interval: -13.6%, 14.5%) and 5.6% for the PHQ-9 diagnostic algorithm (95% prediction interval: -16.4%, 15.0%).

CONCLUSION

PHQ-9 ≥10 substantially overestimates depression prevalence. There is too much heterogeneity to correct statistically in individual studies.

Patient-reported outcomes in the Translational Breast Cancer Research Consortium

Members of the Translational Breast Cancer Research Consortium conducted an expert-driven literature review to identify a list of domains and to evaluate potential measures of these domains for inclusion in a list of preferred measures. Measures were included if they were easily available, free of charge, and had acceptable psychometrics based on published peer-reviewed analyses. A total of 22 domains and 52 measures were identified during the selection process. Taken together, these measures form a reliable and validated list of measurement tools that are easily available and used in multiple cancer trials to assess patient-reported outcomes in relevant patients.

Metallic Nanoislands on Graphene for Monitoring Swallowing Activity in Head and Neck Cancer Patients

There is a need to monitor patients with cancer of the head and neck postradiation therapy, as diminished swallowing activity can result in disuse atrophy and fibrosis of the swallowing muscles. This paper describes a flexible strain sensor comprising palladium nanoislands on single-layer graphene. These piezoresistive sensors were tested on 14 disease-free head and neck cancer patients with various levels of swallowing function: from nondysphagic to severely dysphagic. The patch-like devices detected differences in (1) the consistencies of food boluses when swallowed and (2) dysphagic and nondysphagic swallows. When surface electromyography (sEMG) is obtained simultaneously with strain data, it is also possible to differentiate swallowing vs nonswallowing events. The plots of resistance vs time are correlated to specific events recorded by video X-ray fluoroscopy. Finally, we developed a machine-learning algorithm to automate the identification of bolus type being swallowed by a healthy subject (86.4%. accuracy). The algorithm was also able to discriminate between swallows of the same bolus from either the healthy subject or a dysphagic patient (94.7% accuracy). Taken together, these results may lead to noninvasive and home-based systems for monitoring of swallowing function and improved quality of life.

Comparison of four brief depression screening instruments in ovarian cancer patients: Diagnostic accuracy using traditional versus alternative cutpoints

OBJECTIVES

We compared the diagnostic accuracy of 4 depression screening scales, using traditional and alternative scoring methods, to the gold standard Structured Clinical Interview-DSM IV major depressive episode (MDE) in ovarian cancer patients on active treatment.

METHODS

At the beginning of a new chemotherapy regimen, ovarian cancer patients completed the following surveys on the same day: the Center for Epidemiological Studies Depression Scale (CES-D), the Beck Depression Inventory Fast-Screen for Primary Care (BDI-FastScreen), the Patient Health Questionnaire-9 (PHQ-9), and a 1-item screener ("Are you depressed?"). Each instrument's sensitivity, specificity, positive predictive value (PPV) and negative predictive value were calculated with respect to major depression. To control for antidepressant use, the analyses were re-run for a subsample of patients who were not on antidepressants.

RESULTS

One hundred fifty-three ovarian cancer patients were enrolled into the study. Only fourteen participants met SCID criteria for current MDE (9%). When evaluating all patients regardless of whether they were already being treated with antidepressants, the two-phase scoring approach with an alternate cutpoint of 6 on the PHQ-9 had the best positive predictive value (PPV=32%). Using a traditional cutpoint of 16 on the CES-D resulted in the lowest PPV (5%); using a more stringent cutpoint of 22 resulted in a slightly improved but still poor PPV, 7%.

CONCLUSIONS

Screening with a two-phase PHQ-9 proved best overall, and its accuracy was improved when used with patients who were not already being treated with antidepressants.

Abstract C17: Racial/ethnic variation in psychological distress following an abnormal Pap test

Introduction: While racial/ethnic disparities in cervical cancer incidence are mostly attributed to screening test utilization, lower rates of adherence to diagnostic and clinical follow-up after an abnormal Pap test may contribute to the higher cervical cancer mortality among racial/ethnic minorities. Psychological distress is a known contributor to non-adherence to diagnostic and therapeutic follow-up. The objective of this analysis is to explore racial/ethnic differences in distress following an abnormal Pap.

Methods: Data were collected as part of a clinical trial to evaluate emerging optical technologies for the diagnosis of cervical dysplasia. Participants were non-pregnant women, age ≥18 years, with a recent abnormal Pap test and were recruited at one of the participating colposcopy clinics. Participants answered questionnaires before and after their colposcopy procedure. Distress regarding the abnormal Pap was assessed using the Cervical Dysplasia Distress Questionnaire (CDDQ). The CDDQ measures multiple domains of distress, including those related to the colposcopy procedure (i.e., Tension and Discomfort, Embarrassment), as well as those related to having a positive screening test for cervical cancer (i.e., Health Consequences, Sexual/Reproductive Consequences). Additional items assessed participants' fear of cancer. Subscale scores range from 1 to 4, with higher scores indicating higher levels of distress. Linear regression models were built to assess the differences in distress scores among Hispanic, non-Hispanic black, and non-Hispanic white women after controlling for age and education (Model 1) and age, education, trait anxiety and depression (Model 2). Trait anxiety and depression were respectively measured using the State-Trait Anxiety Inventory for Adults and the Center for Epidemiologic Studies Depression (CESD) scale.

Results: Eighty-five Hispanic, 55 non-Hispanic black, and 86 non-Hispanic white women were included in these analyses. After controlling for age and education, there were statistically significant differences by race/ethnicity in distress scores, particularly for the domains of health consequences (p=0.02) and cancer worry (p = 0.014). In both domains, scores were highest among Hispanic women, compared to non-Hispanic black and non-Hispanic white women (mean health consequences scores = 2.45, 2.02, and 2.16, respectively; mean cancer worry scores = 2.02, 1.62, and 1.75, respectively). Furthermore, these racial/ethnic differences in domain-specific distress remained statistically significant after controlling for differences in underlying depression and trait anxiety.

Discussion: Our results suggest that there are racial/ethnic differences in levels of distress following an abnormal Pap test, particularly related to concerns over health consequences and fear of cancer. Distress scores in these domains were significantly greater among Hispanic women compared to non-Hispanic blacks and non-Hispanic whites. Hispanic women may be more likely to perceive that their abnormal Pap test will have long-term health consequences and develop into cancer. Clinical and ancillary health professionals who communicate Pap test results to Hispanic patients should reinforce messages to address unrealistic fears about disease and alleviate distress.

Identifying dehydration risk in head and neck cancer patients undergoing radiation therapy using remote, sensor-based monitoring: A randomized controlled trial

152

Background: Early identification and mitigation of cancer therapy-induced complications can improve quality of life and reduce complications and health care costs. We are evaluating the efficacy of a system, called CYCORE (CYberinfrastructure for Comparative effectiveness Research), to systematically and accurately collect daily weight, blood pressure, pulse and symptom data from head and neck cancer (HNC) survivors during their 6 to 7-week radiation treatment (RT) regimen using home-based biometric and other sensors integrated with a cyber-physical system. Aims include: 1) evaluate CYCORE’s efficacy in reducing hospitalization and emergency room visits related to dehydration; and, 2) evaluate related impact on costs related to treating dehydration. Methods: Remote, sensor-based monitoring via CYCORE identifies HNC survivors at increased risk for dehydration (i.e., reduced blood pressure and weight, increased pulse, and patient-reported outcomes (PROs) including decreased food and fluid intake). Upon initation of RT, HNC survivors are randomized to either: 1) standard care plus use of the CYCORE system, wherein biometric sensor data and PROs (e.g., pain, nausea, medications, food/fluid intake) are collected ; or, 2) standard care. Outcomes include hospital and emergency room admissions, and related costs. Results: To date, 113 survivors are enrolled (88.9% recruitment and 90.3% retention rates). Those randomized to CYCORE take daily home readings of weight, blood pressure and pulse via Bluetooth-enabled devices, and complete daily PRO assessments on a mobile application. Survivors’ data are available for viewing and clinical decision-making via a Web-based interface by their physicians and other providers. Previously, 59% of HNC survivors on RT showed physiologic signs of dehydration while using the CYCORE system. Worse ratings of nausea and vomiting predicted dehydration risk. Conclusions: CYCORE may serve as one model for integrating mobile and sensor technologies during critical periods of cancer care that occur outside of the clinic setting, and may improve management of treatment side effects, quality of life, and greater satisfaction with care.

Depression and Oropharynx Cancer Outcome

BACKGROUND

Studies have shown a modest relationship between depression and mortality in patients with cancer. Our study addressed methodological weaknesses in the literature by restricting the sample to patients with one cancer type, adjusting for factors known to affect outcome, and following up patients for a sufficient period.

METHODS

We prospectively followed patients newly diagnosed with squamous cell oropharyngeal cancer from the start of radiation therapy until death or until date of last clinical visit. All patients were optimally treated with radiation and sometimes chemotherapy. After adjusting for tumor stage, treatment, comorbidities, smoking, excessive alcohol use, and demographic factors, we assessed the effects of baseline self-reported depression on overall survival and recurrence.

RESULTS

One hundred thirty participants were followed for a median of 5 years. The average age was 56 years, and 83% were male. Eighteen participants died during the study and 15 experienced disease recurrence. Self-reported depression was associated with decreased overall survival duration (hazard ratio = 3.6, 95% confidence interval = 1.2-10.8) and disease recurrence (hazard ratio = 3.8, 95% confidence interval = 1.2-12.2) in multivariate analysis. In addition, smoking was associated with disease recurrence.

CONCLUSIONS

Patients with oropharyngeal cancer may benefit from depression screening and evidence-based treatments, if appropriate. Future studies are needed to determine whether depression is an independent prognostic factor of outcome and to elucidate biobehavioral mechanisms involved in patients with oropharyngeal cancer.

Identifying early dehydration risk with home-based sensors during radiation treatment: a feasibility study on patients with head and neck cancer

BACKGROUND

Systems that enable remote monitoring of patients' symptoms and other health-related outcomes may optimize cancer care outside of the clinic setting. CYCORE (CYberinfrastructure for COmparative effectiveness REsearch) is a software-based prototype for a user-friendly cyberinfrastructure supporting the comprehensive collection and analyses of data from multiple domains using a suite of home-based and mobile sensors. This study evaluated the feasibility of using CYCORE to address early at-home identification of dehydration risk in head and neck cancer patients undergoing radiation therapy.

METHODS

Head and neck cancer patients used home-based sensors to capture weight, blood pressure, pulse, and patient-reported outcomes for two 5-day periods during radiation therapy. Data were sent to the radiation oncologist of each head and neck cancer patient, who viewed them online via a Web-based interface. Feasibility outcomes included study completion rate, acceptability and perceived usefulness of the intervention, and adherence to the monitoring protocol. We also evaluated whether sensor data could identify dehydration-related events.

RESULTS

Fifty patients consented to participate, and 48 (96%) completed the study. More than 90% of patients rated their ease, self-efficacy, and satisfaction regarding use of the sensor suite as extremely favorable, with minimal concerns expressed regarding data privacy issues. Patients highly valued the ability to have immediate access to objective, self-monitoring data related to personal risk for dehydration. Clinician assessments indicated a high degree of satisfaction with the ease of using the CYCORE system and the resulting ability to monitor their patients remotely.

CONCLUSION

Implementing CYCORE in a clinical oncology care setting is feasible and highly acceptable to both patients and providers.

Eat and exercise during radiotherapy or chemoradiotherapy for pharyngeal cancers: use it or lose it

IMPORTANCE

Data support proactive swallowing therapy during radiotherapy (RT) or chemoradiotherapy (CRT) for pharyngeal cancers. The benefits of adherence to a regimen of swallowing exercises and maintaining oral intake throughout treatment are reported, but independent effects are unclear.

OBJECTIVE

To evaluate the independent effects of maintaining oral intake throughout radiotherapy and adherence to preventive swallowing exercise.

DESIGN

Retrospective observational study.

SETTING

The University of Texas MD Anderson Cancer Center, Houston.

PATIENTS

The study included 497 patients treated with definitive RT or CRT for pharyngeal cancer (458 oropharynx, 39 hypopharynx) between 2002 and 2008.

MAIN OUTCOMES AND MEASURES

Swallowing-related end points were final diet after RT or CRT and duration of gastrostomy dependence. Primary independent variables included oral intake status at the end of RT or CRT (no oral intake, partial oral intake, or full oral intake) and adherence to a swallowing exercise regimen. Multiple linear regression and ordered logistic regression models were analyzed.

RESULTS

At the conclusion of RT or CRT, 131 patients (26%) had no oral intake and 74% maintained oral intake (167 partial [34%], 199 full [40%]). Fifty-eight percent (286 of 497) reported adherence to swallowing exercises. Maintenance of oral intake during RT or CRT and swallowing exercise adherence were independently associated with better long-term diet after RT or CRT (P = .045 and P < .001, respectively) and shorter duration of gastrostomy dependence (P < .001 and P = .007, respectively) in models adjusted for tumor and treatment burden.

CONCLUSIONS AND RELEVANCE

The data indicate independent, positive associations of maintenance of oral intake throughout RT or CRT and swallowing exercise adherence with long-term swallowing outcomes. Patients who either eat or exercise fare better than those who do neither. Patients who both eat and exercise have the highest rate of return to a regular diet and shortest duration of gastrostomy dependence.

Impact of cardiovascular comorbidity on ovarian cancer mortality

BACKGROUND

A retrospective cohort study utilizing prospectively collected data was conducted from August 2003 until March 2008 at M.D. Anderson Cancer Center. It is unknown whether cardiovascular comorbidity and chronic stress impact ovarian cancer outcome, which remains poor despite advances in therapy. The purpose of this study was to determine whether cardiovascular disease and markers that may be associated with stress are also associated with survival in patients with ovarian cancer.

METHODS

Participants with newly diagnosed epithelial ovarian cancer were followed until time of death or truncation of study period (median follow-up = 4.2 years; n = 271). Tumor characteristics (stage, tumor grade, histology, debulking status), demographic variables, and cardiovascular comorbidity were documented and compared to overall survival.

RESULTS

Of the nine cardiovascular events tracked during follow-up, venous thromboembolism [VTE; HR, 3.2; 95% confidence interval (CI), 1.8-5.5] and pulmonary hypertension (HR, 8.5; 95% CI, 3.9-18.7) were associated with shorter survival in multivariate analysis. In addition, high tumor grade, suboptimal cytoreduction, and baseline heart rate (HR, 1.02; 95% CI, 1.01-1.04) were related to decreased survival.

CONCLUSION

Careful management of certain cardiovascular comorbidities may extend survival in patients with ovarian cancer. Our findings suggest that increased baseline heart rate and the development of VTE and pulmonary hypertension after cancer diagnosis may be significant predictors of survival in women with ovarian cancer.

IMPACT

Our study emphasizes the importance of identifying and optimally treating tachycardia, VTE, and pulmonary hypertension in conjunction with cancer therapy.

Testis cancer survivors' health behaviors: comparison with age-matched relative and demographically matched population controls

PURPOSE

To determine the prevalence rate of health behaviors in testis cancer survivors and to determine whether the rate of health behaviors in survivors was significantly different than those of their age-matched relative controls and a population-based control group matched for age, sex, education, and income.

PATIENTS AND METHODS

The health behaviors of 162 testis cancer survivors were compared with their age-matched relative controls (n = 74) and an age-, sex-, education-, and income-matched population-based control group (n ranged from 1,123 to 9,775). Health behaviors were assessed with the telephone-administered Behavioral Risk Factor and Surveillance Survey.

RESULTS

Nearly one in five testis cancer survivors reported current smoking and one third reported problem drinking. Only 11% reported having at least five servings of fruits and vegetables per day. Compared with their relative controls, the survivors were more likely to engage in regular exercise. For those participants who drank, survivors were twice as likely to engage in problem drinking and averaged a higher number of drinks compared to their Centers for Disease Control (CDC) controls. Survivors were also half as likely to have at least five servings of fruits and vegetables per day compared with the CDC controls.

CONCLUSION

The overall picture regarding testis cancer survivors' health behaviors was mixed compared with the relative and CDC control groups. Our results suggest that reduced alcohol use and increased fruit and vegetable consumption may be important targets for future disease prevention in testis cancer survivors.

Glucose as a prognostic factor in ovarian carcinoma

BACKGROUND

Research suggests that glucose levels in cancer patients may be an important prognostic indicator. In ovarian tumors, increased expression of glucose transporter 1 (GLUT1), a transmembrane protein responsible for glucose uptake, is related to shorter survival time in ovarian cancer patients. This study tested the hypothesis that higher presurgical glucose levels predict shorter disease-specific survival time and time to recurrence in ovarian cancer patients.

METHODS

Nonfasting plasma glucose levels were determined for 74 patients with ovarian cancer at the time of their presurgical consultation and for 125 ovarian cancer patients in an independent validation set. Survival time and time to recurrence (disease-free interval [DFI]) were ascertained from medical records. Cox proportional hazards regression models were used to estimate the hazard ratio (HR) for survival time and DFI in relation to glucose level, adjusting for body mass index (BMI), stage, grade, and cytoreduction as appropriate.

RESULTS

Higher glucose levels were associated with shorter survival times in univariate analyses (HR, 1.88; P = .05). Multivariate analysis adjusting for stage showed that higher glucose levels were associated with shorter survival times (HR, 2.01; P = .04) and DFI (HR, 2.32; P = .05). In the validation set, higher glucose levels were associated with shorter survival times (HR, 2.01; P = .02) and DFI (HR, 2.48; P = .001) in univariate analysis, although glucose was not independent of the effect of cytoreduction when predicting survival time in this latter set.

CONCLUSIONS

These findings contribute to mounting evidence that glucose levels have prognostic value in ovarian carcinoma.

Randomized pilot test of a lifestyle physical activity intervention for breast cancer survivors

OBJECTIVE

This paper will report the results of a pilot test of a 6-month, 21-session intervention to increase breast cancer survivors' physical activity by teaching them to incorporate short periods of moderate activity into their daily routines (lifestyle intervention). The effect of the intervention on physical performance, quality of life, and physical activity are reported.

METHODS

Sixty breast cancer survivors were randomized to either a lifestyle intervention or a standard care control group. Physical performance, quality of life (Medical outcomes study short form-36 [SF-36]), and physical activity (7-day recall and motivation readiness), were assessed at baseline and 6 months.

RESULTS

The lifestyle group had significantly better performance in the 6-min walk task than the controls (p=0.005) at 6 months. The intervention had positive effects on the bodily pain (p=0.020) and general health (p=0.006) subscales from the SF-36. The lifestyle group had a greater motivational readiness for physical activity at 6-month than standard care, but no significant differences were seen between the two in terms of number of minutes of moderate or more intense physical activity or number of days on which they did > or =30 min of moderate or more intense activity.

CONCLUSIONS

Despite the small sample size, the lifestyle intervention showed promise for improving physical functioning and quality of life and increasing physical activity, and should be tested in a larger randomized trial.

PRACTICE IMPLICATIONS

If the lifestyle approach is shown to be effective in a larger trial, it represents a highly feasible intervention that it can be delivered to cancer survivors by health care institutions or community organizations without dedicated exercise facilities and equipment.

Predictors of sexual functioning in ovarian cancer patients

PURPOSE

To characterize sexual functioning of ovarian cancer patients and identify factors predicting sexual activity, functioning or satisfaction, discomfort, and habit or frequency.

PATIENTS AND METHODS

Data were collected on 232 women with epithelial ovarian cancer, 47% of whom were receiving treatment.

RESULTS

Fifty percent of the patients had engaged in sexual activity in the past month. Of those who were sexually active, 47% reported no or little desire, 80% reported problems with vaginal dryness, and 62% reported pain or discomfort during penetration. Of those who were sexually inactive, reasons included no partner (44.1%), lack of interest (38.7%), physical problems making sex difficult (23.4%), and fatigue (10.8%). Partner factors also were identified, including physical problems (16.2%), lack of interest (15.3%), and fatigue (5.4%). A multivariate model was used to predict sexual activity and included demographic, medical, and psychosocial factors as predictors. Women who were married (P <.001), were younger than 56 years (P <.001), were not receiving active treatment (P <.01), had a longer time since original diagnosis (P =.104), and liked the appearance of their bodies (P =.004) were more likely to be sexually active. Univariate analyses indicated that demographic, medical, and psychosocial factors are significantly associated with sexual functioning or satisfaction, sexual discomfort, and sexual frequency or habit.

CONCLUSION

Sexual rehabilitation for ovarian cancer patients should address management of physical and psychologic symptoms and include the patient's partner when appropriate.

Patient distress and satisfaction with optical spectroscopy in cervical dysplasia detection

OBJECTIVE

The aim of this investigation was to evaluate the impact of optical spectroscopy, a new approach for the detection of cervical dysplasia, on patient well-being and satisfaction.

STUDY DESIGN

Patient distress and satisfaction with optical spectroscopy compared with the Papanicolaou test and colposcopically directed biopsy were measured in a volunteer sample of 314 women with no history of abnormal Papanicolaou test findings.

RESULTS

Participants reported significantly less pain and anxiety (P<.001) during optical spectroscopy than during the Papanicolaou test or colposcopically directed biopsy. Generally, participants found spectroscopy equal to the Papanicolaou test and to biopsy on a variety of questions that measured satisfaction. There were statistically significant differences between spectroscopy and the Papanicolaou test or biopsy on issues such as the discomfort and fear caused by the test, the amount of time taken, the room lighting, and perceptions of accuracy.

CONCLUSION

That patients reported less distress during spectroscopy than during a Papanicolaou test, colposcopy, or biopsy suggests the possibility of improved adherence to cervical cancer screening and follow-up in settings in which it is used.

Blood pressure and symptoms of depression and anxiety: a prospective study

This study investigated whether symptoms of depression and anxiety were related to the development of elevated blood pressure in initially normotensive adults. The study's hypothesis was addressed with an existing set of prospective data gathered from an age-, sex-, and weight-stratified sample of 508 adults. Four years of follow-up data were analyzed both with logistic analysis, which used hypertension (blood pressure > or =140 mm Hg systolic or 90 mm Hg diastolic) as the dependent variable, and with multiple regression analysis, which used change in blood pressure as the dependent variable. Five physical risk factors for hypertension (age, sex, baseline body mass index, family history of hypertension, and baseline blood pressure levels) were controlled for in the regression analyses. Use of antidepressant/antianxiety and antihypertensive medications were controlled for in the study. Of the 433 normotensive participants who were eligible for our study, 15% had missing data in the logistic regression analysis focusing on depression (n = 371); similarly, 15% of the eligible sample had missing data in the logistic regression using anxiety as the psychological variable of interest (n = 370). Both logistic regression analyses showed no significant relationship for either depression or anxiety in the development of hypertension. The multiple regression analyses (n = 369 for the depression analysis; n = 361 for the anxiety analysis) similarly showed no relationship between either depression or anxiety in changes in blood pressure during the 4-year follow-up. Thus, our results do not support the role of depressive or anxiety symptoms in the development of hypertension in our sample of initially normotensive adults.
