Experiences of patients with peritoneal carcinomatosis-related complex care needs and their caregivers.

BACKGROUND: Patients with peritoneal carcinomatosis (PC) frequently undergo palliative procedures, yet these patients and their caregivers report being unprepared to manage ostomies, drains, and other complex care needs at home. The purpose of this study was to characterize the unique needs of these patients and their caregivers during care transitions. METHODS: Patients completed measures of health status and advance care planning, caregivers completed measures of preparedness and burden, and all participants completed measures of depression and anxiety. Participants detailed their experiences in individual, semi-structured interviews. We analyzed data using descriptive statistics and conventional content analysis. RESULTS: Sixty-one patients and 39 caregivers completed baseline measures. Twenty-four (39.3%) patients acknowledged their terminal illness and seven (11.5%) had discussed end-of-life care preferences with clinicians. Most (26/39, 66.7%) caregivers provided daily care. Among caregivers who managed symptoms, few were taught how to do so (6/20, 30%). Seven patients (11.5%) and seven caregivers (17.9%) met case criteria for anxiety, while 15 patients (24.6%) and two caregivers (5.1%) met case criteria for depression. Interview participants described a diagnosis of PC as a turning point for which there is no road map and identified the need for health systems change to minimize suffering. CONCLUSION: Patients with PC and their caregivers are highly burdened by symptoms and care needs. Patients' prognostic understanding and advance care planning are suboptimal. Interventions that train patients with PC and their caregivers to perform clinical care tasks, facilitate serious illness conversations, and provide psychosocial support are needed.

Improving the palliative-procedure decision-making process for patients with peritoneal carcinomatosis: A secondary analysis.

BACKGROUND: Peritoneal carcinomatosis (PC) is common in patients with advanced gynecologic and gastrointestinal cancers. Frequently, patients with PC undergo palliative surgery or procedures to manage disease-related complications and side effects. However, there are limited data regarding patients' and family caregivers' decision-making processes about these procedures. Thus, we sought to describe the decision-making experiences of patients with PC who elect to pursue palliative surgical procedures and their family caregivers. METHODS: We conducted a secondary analysis of qualitative data collected during a pilot randomized controlled trial of BOLSTER, a nurse-led telehealth intervention for patients with PC and their caregivers after an acute hospitalization and palliative procedure. Participants in both study arms described their experiences in semi-structured interviews. We re-analyzed coded qualitative data with a focus on understanding decision-making experiences surrounding palliative surgery and procedures using conventional content analysis. RESULTS: Interviews from 32 participants, 23 patients and 9 caregivers, were analyzed. Participants reported their decision-making was complicated by illness uncertainty and a desire for clear, effective communication with surgical and medical oncology teams. Participants requested more information about the impact of palliative procedures on their daily life. Several also noted that, without improved understanding, a misalignment between patient and family caregiver goals and palliative procedures may inadvertently increase suffering. CONCLUSION: Discussions related to patients' goals and preferences can improve the quality of treatment decision-making in patients with PC and their caregivers. Future research should test interventions to improve advanced cancer patients' illness understanding and decision-making surrounding palliative surgery and procedures.

Feasibility and acceptability of a nurse-led telehealth intervention (BOLSTER) to support patients with peritoneal carcinomatosis and their caregivers: A pilot randomized clinical trial.

OBJECTIVE: Patients with advanced gynecologic (GYN) and gastrointestinal (GI) cancers frequently develop peritoneal carcinomatosis (PC), which limits prognosis and diminishes health-related quality of life (HRQoL). Palliative procedures may improve PC symptoms, yet patients and caregivers report feeling unprepared to manage ostomies, catheters, and other complex needs. Our objectives were to (1) assess the feasibility of an efficacy trial of a nurse-led telehealth intervention (BOLSTER) for patients with PC and their caregivers; and (2) assess BOLSTER's acceptability, potential to improve patients' HRQoL and self-efficacy, and potential impact on advance care planning (ACP). METHODS: Pilot feasibility RCT. Recently hospitalized adults with advanced GYN and GI cancers, PC, and a new complex care need and their caregivers were randomized 1:1 to BOLSTER or enhanced discharge planning (EDP). We defined feasibility as a ≥ 50% approach-to-consent ratio and acceptability as ≥70% satisfaction with BOLSTER. We assessed patients' HRQoL and self-efficacy at baseline and six weeks, then compared the proportion experiencing meaningful improvements by arm. ACP documentation was identified using natural language processing. RESULTS: We consented 77% of approached patients. In the BOLSTER arm, 91.0% of patients and 100.0% of caregivers were satisfied. Compared to EDP, more patients receiving BOLSTER experienced improvements in HRQoL (68.4% vs. 40.0%) and self-efficacy for managing symptoms (78.9% vs. 35.0%) and treatment (52.9% vs. 42.9%). The BOLSTER arm had more ACP documentation. CONCLUSIONS: BOLSTER is a feasible and acceptable intervention with the potential to improve patients' HRQoL and promote ACP. An efficacy trial comparing BOLSTER to usual care is underway. TRIAL REGISTRATION: ClinicalTrials.gov: NCT03367247; PI: Wright.

Pilot randomized trial of an acceptance-based telehealth intervention for women with ovarian cancer and PARP inhibitor-related fatigue.

OBJECTIVE: Poly(ADP-ribose) polymerase inhibitors (PARPi) have dramatically changed treatment for advanced ovarian cancer, but nearly half of patients experience significant fatigue. We conducted a two-site pilot randomized trial to evaluate the feasibility, acceptability, and preliminary efficacy of a brief, acceptance-based telehealth intervention (REVITALIZE) designed to reduce fatigue interference in patients on PARPi. METHODS: From June 2021 to April 2022, 44 participants were randomized 1:1 to REVITALIZE (6 weekly one-on-one sessions+booster) or enhanced usual care. Feasibility was defined as: ≥50% approach-to-consent among potentially eligible patients and ≥70% completion of 12-week follow-up assessment; acceptance was <20% participants reporting burden and <20% study withdrawal. Fatigue, anxiety, depression, and quality of life were assessed at baseline, 4-, 8- and 12-weeks. RESULTS: Among 44 participants (mean age = 62.5 years, 81.8% stage III/IV disease), the study was feasible (56.4% approach-to-consent ratio, 86.3% completion of 12-week assessment) and acceptable (0% reporting burden, 11.3% study withdrawal). At 12-week follow-up, REVITALIZE significantly reduced fatigue interference (Cohen's d = 0.94, p = .008) and fatigue severity (d = 0.54, p = .049), and improved fatigue levels (d = 0.62, p = .04) relative to enhanced usual care. REVITALIZE also showed promise for improved fatigue self-efficacy, fatigue catastrophizing, anxiety, depression, and quality of life (ds = 0.60-0.86, p ≥ .05). Compared with enhanced usual care, REVITALIZE participants had fewer PARPi dose reductions (6.7% vs. 19.0%), and dose delays (6.7% vs. 23.8%). CONCLUSIONS: Among fatigued adults with ovarian cancer on PARPi, a brief, acceptance-based telehealth intervention was feasible, acceptable, and demonstrated preliminary efficacy in improving fatigue interference, severity, and levels. REVITALIZE is a novel, scalable telehealth intervention worthy of further investigation.

Identification of distinct symptom profiles in patients with gynecologic cancers using a pre-specified symptom cluster.

PURPOSE: Pain, fatigue, sleep disturbance, and depression are four of the most common symptoms in patients with gynecologic cancer. The purposes were to identify subgroups of patients with distinct co-occurring pain, fatigue, sleep disturbance, and depression profiles (i.e., pre-specified symptom cluster) in a sample of patients with gynecologic cancer receiving chemotherapy and assess for differences in demographic and clinical characteristics, as well as the severity of other common symptoms and QOL outcomes among these subgroups. METHODS: Patients completed symptom questionnaires prior to their second or third cycle of chemotherapy. Latent profile analysis was used to identify subgroups of patients using the pre-specified symptom cluster. Parametric and nonparametric tests were used to evaluate for differences between the subgroups. RESULTS: In the sample of 233 patients, two distinct latent classes were identified (i.e., low (64.8%) and high (35.2%)) indicating lower and higher levels of symptom burden. Patients in high class were younger, had child care responsibilities, were unemployed, and had a lower annual income. In addition, these women had a higher body mass index, a higher comorbidity burden, and a lower functional status. Patients in the high class reported higher levels of anxiety, as well as lower levels of energy and cognitive function and poorer quality of life scores. CONCLUSIONS: This study identified a number of modifiable and non-modifiable risk factors associated with membership in the high class. Clinicians can use this information to refer patients to dieticians and physical therapists for tailored interventions.

Comparing adult-child and spousal caregiver burden and potential contributors.

BACKGROUND: Adult-children caring for a parent with cancer comprise a significant segment of caregivers. Yet less is known about adult-child caregivers, their burden, or caregivers' and patients' gender's impact, which may differ from the well-studied spousal caregiver. This knowledge gap may hinder efforts to ameliorate adult-children's caregiver burden. METHODS: We analyzed caregiver surveys from the Cancer Care Outcomes Research and Surveillance Consortium, a multi-regional population-based study of patients with colorectal or lung cancer. Using t tests and multivariate regression models, we assessed whether adult-child and spousal caregivers' caregiving responsibilities and social/emotional and financial burdens differed and used structural equation models (SEMs) to examine mediating factors. RESULTS: Compared with spouses/partners (N = 1007), adult-children (N = 227) spent less time caregiving (14 vs 23 hours/week; P < .001), but experienced higher social/ emotional burden (P < .01). In models adjusted for objective caregiving burden measures and demographics, adult-children's social/emotional (P < .05) and financial burdens (P < .01) were greater than spouses'. Poor communication quality was associated with greater social/emotional burden for both groups (P < .05). SEMs indicated that gender concordance between caregivers and patients (eg, daughters caring for mothers) and caregiver employment increased the difference between adult-child and spouses' social/emotional burden, whereas caregiver-patient relationship quality reduced it. CONCLUSIONS: Adult-children spend less time caregiving than spouses/partners, but have higher social/emotional and financial caregiving burdens, partially due to adult-children's employment, caregiver-patients' gender concordance, and relationship quality. Gender concordance's contribution to greater social/emotional burden adds important context to prior findings, indicating female caregivers experience the most burden. Interventions that improve caregiver-patient communication may reduce both adult-child and spousal caregiver burden.

Combined PARP and HSP90 inhibition: preclinical and Phase 1 evaluation in patients with advanced solid tumours.

PURPOSE: PARP inhibitor resistance may be overcome by combinatorial strategies with agents that disrupt homologous recombination repair (HRR). Multiple HRR pathway components are HSP90 clients, so that HSP90 inhibition leads to abrogation of HRR and sensitisation to PARP inhibition. We performed in vivo preclinical studies of the HSP90 inhibitor onalespib with olaparib and conducted a Phase 1 combination study. PATIENTS AND METHODS: Tolerability and efficacy studies were performed in patient-derived xenograft(PDX) models of ovarian cancer. Clinical safety, tolerability, steady-state pharmacokinetics and preliminary efficacy of olaparib and onalespib were evaluated using a standard 3 + 3 dose-escalation design. RESULTS: Olaparib/onalespib exhibited anti-tumour activity against BRCA1-mutated PDX models with acquired PARPi resistance and PDX models with RB-pathway alterations(CDKN2A loss and CCNE1 overexpression). Phase 1 evaluation revealed that dose levels up to olaparib 300 mg/onalespib 40 mg and olaparib 200 mg/onalespib 80 mg were safe without dose-limiting toxicities. Coadministration of olaparib and onalespib did not appear to affect the steady-state pharmacokinetics of either agent. There were no objective responses, but disease stabilisation ≥24 weeks was observed in 7/22 (32%) evaluable patients including patients with BRCA-mutated ovarian cancers and acquired PARPi resistance and patients with tumours harbouring RB-pathway alterations. CONCLUSIONS: Combining onalespib and olaparib was feasible and demonstrated preliminary evidence of anti-tumour activity.

How does patient-centered communication in ovarian cancer care enhance patient well-being? A mixed methods study.

OBJECTIVE: Greater perceived patient-centered communication (PCC) is associated with better health-related quality of life (HRQoL) in patients with ovarian cancer. Quantitative measures of PCC and HRQoL do little to explain this association. We interviewed patients with high and low ratings of PCC to understand how it is associated with HRQoL. METHODS: Explanatory sequential mixed methods study. Participants were English-speaking U.S. adults with ovarian cancer. We assessed PCC with the Patient-Centered Communication - Cancer (PCC-Ca)-36 (possible score range 1-5; higher scores represent greater patient-centeredness), and purposively sampled 14 participants with total scores in the top and bottom quartiles. Participants completed individual, semi-structured interviews about their communication experiences. Guided by the National Cancer Institute Framework for PCC in Cancer Care, we analyzed interview transcripts using directed content analysis. We integrated survey and interview findings in a joint display. RESULTS: Among 176 survey respondents, PCC-Ca-36 total scores ranged from 1.7 to 5.0. Participants with scores in the top quartile (4.8-5.0) perceived clinicians as proactive and attentive to psychosocial concerns. Those with scores in the bottom quartile (1.7-3.5) described not feeling known as an individual and receiving limited support for self-management. CONCLUSIONS: The association between PCC and QoL may be partially explained by differences in perceived support for psychosocial concerns and self-management. PCC may facilitate receipt of proactive, personalized care.

Racial and ethnic disparities in cancer caregiver burden and potential sociocultural mediators.

PURPOSE: Black and Hispanic cancer patients experience many worse care quality and health outcomes than non-Hispanic White patients, yet less is known about disparities in caregiving responsibilities and burden among cancer caregivers. METHODS: We analyzed cross-sectional data from Cancer Care Outcomes Research and Surveillance consortium, a large multi-regional, population-based study of colorectal and lung cancer patients and their caregivers. Bivariate and multivariable regression models assessed differences by racial and ethnic groups in caregiving responsibilities and social/emotional, financial, and health burdens. Structural equation models estimated whether sociocultural resources (social support, caregiving preparedness, caregiver-patient communication) mediated racial and ethnic differences in caregiver burden. RESULTS: Compared with non-Hispanic White caregivers (N = 1,169), Black (N = 220) and Hispanic (N = 84) caregivers spent more time caregiving (18 vs. 26 vs. 26 h/week; P < 0.001), completed more tasks (6.8 vs. 7.6 vs. 8.7; P < 0.05), and reported greater financial burden (P = 0.02). Yet, compared to non-Hispanic Whites, Hispanic caregivers reported similar social/emotional and health burdens, while Black caregivers reported lower levels (P < 0.01). In adjusted models, disparities in financial burden disappeared, and Hispanic caregivers had less health burden than non-Hispanic White caregivers (P = 0.01). Social support and/or caregiving preparedness partially mediated the Black-White gap for all three types of burdens. CONCLUSIONS: Black and Hispanic cancer caregivers perform more caregiving and report greater financial burden than non-Hispanic White caregivers, but experience lower or equivalent social/emotional and health burdens. Racial differences in caregivers' social support and caregiving preparedness levels partially explain Black-White burden differences. Research and policy should address Black and Hispanic caregivers' increased financial burden.

Cancer patients' experiences with medicinal cannabis-related care.

BACKGROUND: Little is known about medical cannabis (MC)-related care for patients with cancer using MC. METHODS: Semistructured telephone interviews were conducted in a convenience sample of individuals (n = 24) with physician-confirmed oncologic diagnoses and state/district authorization to use MC (Arizona, California, Florida, Illinois, Massachusetts, Oregon, New York, and Washington, DC) from April 2017 to March 2019. Standard qualitative techniques were used to assess the degree of MC-related health care oversight, MC practices, and key information sources. RESULTS: Among 24 participants (median age, 57 years; range, 30-71 years; 16 women [67%]), MC certifications were typically issued by a professional new to a patient's care after a brief, perfunctory consultation. Patients disclosed MCuse to their established medical teams but received little medical advice about whether and how to use MC. Patients with cancer used MC products as multipurpose symptom management and as cancer-directed therapy, sometimes in lieu of standard-of-care treatments. Personal experimentation, including methodical self-monitoring, was an important source of MC know-how. Absent formal advice from medical professionals, patients relied on nonmedical sources for MC information. CONCLUSIONS: Patients with cancer used MC with minimal medical oversight. Most received MC certifications through brief meetings with unfamiliar professionals. Participants desired but were often unable to access high-quality clinical information about MC from their established medical teams. Because many patients are committed to using MC, a product sustained by a growing industry, medical providers should familiarize themselves with the existing data for MM and its limitations to address a poorly met clinical need.

Lived experiences of women reporting fatigue during PARP inhibitor maintenance treatment for advanced ovarian cancer: A qualitative study.

OBJECTIVE: Oral PARP inhibitors (PARPi) have dramatically changed the treatment landscape for patients with advanced ovarian cancer. However, a subset of patients discontinue PARPi due to treatment-related fatigue. The current study sought to explore patients' lived experiences with fatigue on PARPi. METHODS: We conducted individual semi-structured interviews with N = 23 women receiving PARPi for advanced ovarian cancer who reported moderate to severe fatigue. Audiotaped interviews were transcribed and we used thematic analysis to code transcripts for emergent themes. RESULTS: Four overarching themes emerged. First, participants described their fatigue as milder than what they experienced on intravenous chemotherapy, but noted it consistently limited their daily activities, including work, and interfered with participation in family and social events. Second, fatigue negatively impacted participants' sense of self and identity. Third, most wanted to continue treatment and believed discontinuing PARPi would lead to a cancer recurrence or death. Finally, many participants reported that their support networks were unaware of their ongoing cancer treatment or the resulting fatigue; a situation that may prove isolating and result in reduced social support. CONCLUSIONS: Our findings underscore patients' persistent experience of fatigue on PARPi, the impact of fatigue on multiple domains of functioning, and a lack of understanding of side effects resulting from oral maintenance treatments among patients' social networks. Our findings highlight the need for interventions to address treatment-related fatigue to limit the negative impacts of fatigue on ovarian cancer patients' well-being.

Perceived patient-centered communication, quality of life, and symptom burden in individuals with ovarian cancer.

OBJECTIVE: To describe perceptions of patient-centered communication (PCC); assess whether physician specialty, patient characteristics, or health system characteristics are associated with PCC; and identify associations between PCC, health-related quality of life (HRQoL), and symptom burden among individuals with ovarian cancer. METHODS: Cross-sectional, descriptive survey of English-speaking adults with ovarian cancer. PCC, HRQoL, and ovarian cancer symptom burden were assessed with the PCC-Ca-36, the FACT-G, and the FOSI-18, respectively. PCC-Ca-36 scores were summarized using descriptive statistics. Predictors of PCC-Ca-36, FACT-G, and FOSI-18 scores were identified using multiple linear regression. RESULTS: Participants (n = 176) had a mean age of 59.4 years (SD = 12.1). The majority (65.9%) had advanced-stage disease, while 42.0% were receiving treatment. The mean PCC-Ca-36 total score was 4.09 (SD = 0.78) out of a possible 5, indicating participants often perceived that clinicians engaged in PCC. Among the PCC functions, participants reported that clinicians least often enabled patient self-management (M = 3.65, SD = 0.99), responded to emotions (M = 3.84, SD = 1.04), and managed uncertainty (M = 3.91, SD = 0.93). In multivariable analyses, neither physician specialty nor patient and health system characteristics were significantly associated with overall PCC. Greater overall PCC predicted better overall HRQoL; better social/family, emotional, and functional well-being; and lower overall and physical symptom burden (all p ≤ 0.05). CONCLUSION: Greater PCC is significantly associated with better HRQoL and lower symptom burden among individuals with ovarian cancer. PRACTICE IMPLICATIONS: Promotion of PCC is a promising strategy to improve patient-reported outcomes in the ovarian cancer care setting.

Embedding a genetic counselor into oncology clinics improves testing rates and timeliness for women with ovarian cancer.

OBJECTIVE: Germline genetic testing is crucial to the care of ovarian cancer patients, and as part of the guideline-based care for ovarian cancer patient's adherence to this recommendation has been low. We sought to determine whether embedding a genetic counselor (GC) within a medical and gynecologic oncology clinic would increase testing rates and improve the timeliness of testing. METHODS: Prospective cohort study of 358 ovarian cancer patients seen by medical and gynecologic oncologists between 2013 and 2015. Rates of referrals, completion of counseling, and genetic testing and timeliness of counseling were abstracted before and after a GC was embedded in the clinic in 2014. An additional year of data (2015) was collected to evaluate sustainability of the intervention. RESULTS: Between 2013 and 2015, 88-92% of women were referred for genetic testing, but in 2013 only 66% completed counseling and 61% were tested. After a GC was embedded in the clinic in 2014, more than 80% of referred women completed counseling and germline genetic testing. Time to genetic counseling also decreased from a median of 107 to 40 days, irrespective of age and cancer family history (p < 0.01). CONCLUSIONS: Embedding a GC into the workflow for ovarian cancer patients is an effective way of improving access to genetic counseling, testing rates, and the timeliness of testing.

Stepping into survivorship pilot study: Harnessing mobile health and principles of behavioral economics to increase physical activity in ovarian cancer survivors.

OBJECTIVE: Physical activity improves physical function, quality of life, and mental health, yet fewer than 80% of ovarian cancer survivors meet activity guidelines. This pilot intervention study aimed to increase physical activity in ovarian cancer survivors by leveraging principles of behavioral economics, gamification, and social support. METHODS: This 24-week study (12-week intervention; 12-week follow-up) enrolled women with ovarian cancer after completion of first-line treatment with a self-selected "teammate." Participants used Fitbits to measure daily steps, select an increased step goal, and enroll in a collaborative game, including points and levels for achieving step goals. Primary outcomes were feasibility (defined a priori as ≥60% approach-to-consent ratio and ≥ 70% adherence to Fitbit), acceptability (≤20% of participants reporting burden or regret for participation) and preliminary efficacy (≥70% reporting increased motivation); exploratory outcomes included change in steps. RESULTS: We recruited 24 participants (mean age = 63 years, range = 37-79 years) with a 94% approach-to-consent ratio. All participants completed the intervention with 94% tracker adherence. At 24-week follow-up, 1/24 (≤5%) of participants reported burden; 0/24 (0%) reported regret for study participation; and 22/24 (>90%) agreed/strongly agreed that "the study motivated me to increase activity levels." Participants' mean daily steps were 6210.7 (±3328.1) at baseline and increased to 7643 (± 3610.9) steps (p < 0.001) during the 12-week intervention. CONCLUSIONS: This pilot study demonstrated feasibility, acceptability, and preliminary efficacy, justifying a larger randomized clinical trial to test efficacy at increasing activity levels. Future studies should examine strategies for maintaining increased activity levels in survivors over time.

Incorporating patient centered benefits as endpoints in randomized trials of maintenance therapies in advanced ovarian cancer: A position paper from the GCIG symptom benefit committee.

BACKGROUND: Quality of life and patient reported outcome measures (PROMs) are important secondary endpoints and incorporated in most contemporary clinical trials. There have been deficiencies in their assessment and reporting in ovarian cancer clinical trials, particularly in trials of maintenance treatment where they are of particular importance. The Gynecologic Cancer InterGroup (GCIG) symptom benefit committee (SBC) recently convened a brainstorming meeting with representation from all collaborative groups to address questions of how to best incorporate PROMs into trials of maintenance therapies to support the primary endpoint which is usually progression free survival (PFS). These recommendations should harmonize the collection, analysis and reporting of PROM's across future GCIG trials. METHODS: Through literature review, trials analysis and input from international experts, the SBC identified four relevant topics to address with respect to promoting the role of PROMs to support the PFS endpoint in clinical trials of maintenance treatment for OC. RESULTS: The GCIG SBC unanimously accepted the importance of integrating PROM's in future maintenance trials and developed four guiding principles to be considered early in trial design. These include 1) adherence to SPIRIT-PRO guidelines, 2) harmonization of selection, collection and reporting of PROM's; 3) combining Health Related Quality of Life (HRQL) measures with clinical endpoints and 4) common approaches to dealing with incomplete HRQL data. CONCLUSIONS: Close attention to incorporating HRQL and PROM's is critical to interpret the results of ovarian cancer clinical trials of maintenance therapies. There should be a consistent approach to assessing and reporting patient centered benefits across all GCIG trials to enable cross trial comparisons which can be used to inform practice.

Leveraging mobile health technology and research methodology to optimize patient education and self-management support for advanced cancer pain.

PURPOSE: Patient education is critical for management of advanced cancer pain, yet the benefits of psychoeducational interventions have been modest. We used mobile health (mHealth) technology to better meet patients' needs. METHODS: Using the Agile and mHealth Development and Evaluation Frameworks, a multidisciplinary team of clinicians, researchers, patients, and design specialists followed a four-phase iterative process to develop comprehensive, tailored, multimedia cancer pain education for a patient-facing smartphone application. The target population reviewed the content and provided feedback. RESULTS: The resulting application provides comprehensive cancer pain education spanning pharmacologic and behavioral aspects of self-management. Custom graphics, animated videos, quizzes, and audio-recorded relaxations complemented written content. Computable algorithms based upon daily symptom surveys were used to deliver brief, tailored motivational messages that linked to more comprehensive teaching. Patients found the combination of pharmacologic and behavioral support to be engaging and helpful. CONCLUSION: Digital technology can be used to provide cancer pain education that is engaging and tailored to individual needs. A replicable interdisciplinary and patient-centered approach to intervention development was advantageous. mHealth interventions may be a scalable approach to improve cancer pain. Frameworks that merge software and research methodology can be useful in developing interventions.

Patterns and predictors of cancer-related fatigue in ovarian and endometrial cancers: 1-year longitudinal study.

BACKGROUND: Fatigue is a common and distressing symptom for patients with gynecologic cancers. Few studies have empirically examined whether it spontaneously resolves. This study was aimed at identifying longitudinal patterns of fatigue and predictors of clinically significant fatigue 1 year after treatment completion. METHODS: This was a prospective cohort study of women with newly diagnosed ovarian (n = 81) or endometrial cancer (n = 181) that did not progress or recur within 1 year of treatment completion. Symptoms of fatigue, depression, and anxiety were assessed after surgery and 6 and 12 months after treatment completion with the Fatigue Assessment Scale and the Hospital Anxiety and Depression Scale. Patients' fatigue scores over time were classified (scores of 22-50, clinically significant; scores of 10-21, not clinically significant). Logistic regression models were fit to examine associations between fatigue and patient characteristics. RESULTS: Among 262 participants, 48% reported clinically significant fatigue after surgery. One year later, 39% reported fatigue. There were 6 patterns over time: always low (37%), always high (25%), high then resolves (18%), new onset (10%), fluctuating (6%), and incidental (5%). Patients with fatigue after surgery were more likely to report fatigue at 12 months in comparison with others (odds ratio [OR], 6.08; 95% confidence interval [CI], 2.82-13.11; P < .001). Patients with depressive symptoms also had higher odds of fatigue (OR, 3.36; 95% CI, 1.08-10.65; P = .039), although only one-third of fatigued patients reported depressive symptoms. CONCLUSION: Nearly half of women with gynecologic cancers had clinically significant fatigue after surgery, whereas 44% and 39% had fatigue 6 months and 1 year later; this suggests that spontaneous regression of symptoms is relatively rare. Women who reported fatigue, depressive symptoms, or 2 or more medical comorbidities had higher odds of reporting fatigue 1 year later. Future studies should test scalable interventions to improve fatigue in women with gynecologic cancers.

Combined pembrolizumab and pegylated liposomal doxorubicin in platinum resistant ovarian cancer: A phase 2 clinical trial.

OBJECTIVE: Pegylated liposomal doxorubicin (PLD) in vitro may have immunomodulatory abilities and preclinical evidence suggests it synergizes with immune checkpoint blockade. We hypothesized that combining PLD and pembrolizumab would be active in patients with platinum-resistant ovarian cancer (PROC). METHODS: This was a single-arm, multi-center phase II trial. Eligible patients had PROC with ≤2 prior lines of cytotoxic therapy for recurrent or persistent disease. Twenty-six patients were enrolled and given pembrolizumab 200 mg intravenously (IV) every 3 weeks and PLD 40 mg/m2 IV every 4 weeks. Patients were assessed radiographically every 8 weeks. The primary endpoint was clinical benefit rate (CBR), defined as complete response (CR) + partial response (PR) + stable disease (SD) ≥24 weeks. The study was powered to detect an improvement in CBR from 25% to 50%, with rejection of the null hypothesis if at least 10 patients achieved clinical benefit. T-cell inflamed gene expression profiles (GEP) and PD-L1 were assessed and correlated with clinical outcome. RESULTS: Twenty-three patients were evaluable for best overall response. The study satisfied its primary endpoint, with 12 patients achieving clinical benefit for a CBR of 52.2% (95% CI 30.6-73.2%). There were 5 PRs (21.7%) and 1 CR (4.3%), for an overall response rate (ORR) of 26.1%. Six patients had SD lasting at least 24 weeks. Combination therapy was well tolerated without unexpected toxicities. CONCLUSIONS: The combination of pembrolizumab and PLD was manageable, without unexpected toxicities, and showed preliminary evidence of clinical benefit in the treatment of platinum resistant ovarian cancer. ORR and median PFS of combination therapy in this study was higher than historical comparisons of PLD alone or anti-PD-1/PD-L1 agents alone. TRIAL REGISTRATION: Clinicaltrials.gov identifier: NCT02865811.

Landscape of genomic alterations in cervical carcinomas.

Cervical cancer is responsible for 10-15% of cancer-related deaths in women worldwide. The aetiological role of infection with high-risk human papilloma viruses (HPVs) in cervical carcinomas is well established. Previous studies have also implicated somatic mutations in PIK3CA, PTEN, TP53, STK11 and KRAS as well as several copy-number alterations in the pathogenesis of cervical carcinomas. Here we report whole-exome sequencing analysis of 115 cervical carcinoma-normal paired samples, transcriptome sequencing of 79 cases and whole-genome sequencing of 14 tumour-normal pairs. Previously unknown somatic mutations in 79 primary squamous cell carcinomas include recurrent E322K substitutions in the MAPK1 gene (8%), inactivating mutations in the HLA-B gene (9%), and mutations in EP300 (16%), FBXW7 (15%), NFE2L2 (4%), TP53 (5%) and ERBB2 (6%). We also observe somatic ELF3 (13%) and CBFB (8%) mutations in 24 adenocarcinomas. Squamous cell carcinomas have higher frequencies of somatic nucleotide substitutions occurring at cytosines preceded by thymines (Tp*C sites) than adenocarcinomas. Gene expression levels at HPV integration sites were statistically significantly higher in tumours with HPV integration compared with expression of the same genes in tumours without viral integration at the same site. These data demonstrate several recurrent genomic alterations in cervical carcinomas that suggest new strategies to combat this disease.

Threats of Bots and Other Bad Actors to Data Quality Following Research Participant Recruitment Through Social Media: Cross-Sectional Questionnaire.

BACKGROUND: Recruitment of health research participants through social media is becoming more common. In the United States, 80% of adults use at least one social media platform. Social media platforms may allow researchers to reach potential participants efficiently. However, online research methods may be associated with unique threats to sample validity and data integrity. Limited research has described issues of data quality and authenticity associated with the recruitment of health research participants through social media, and sources of low-quality and fraudulent data in this context are poorly understood. OBJECTIVE: The goal of the research was to describe and explain threats to sample validity and data integrity following recruitment of health research participants through social media and summarize recommended strategies to mitigate these threats. Our experience designing and implementing a research study using social media recruitment and online data collection serves as a case study. METHODS: Using published strategies to preserve data integrity, we recruited participants to complete an online survey through the social media platforms Twitter and Facebook. Participants were to receive $15 upon survey completion. Prior to manually issuing remuneration, we reviewed completed surveys for indicators of fraudulent or low-quality data. Indicators attributable to respondent error were labeled suspicious, while those suggesting misrepresentation were labeled fraudulent. We planned to remove cases with 1 fraudulent indicator or at least 3 suspicious indicators. RESULTS: Within 7 hours of survey activation, we received 271 completed surveys. We classified 94.5% (256/271) of cases as fraudulent and 5.5% (15/271) as suspicious. In total, 86.7% (235/271) provided inconsistent responses to verifiable items and 16.2% (44/271) exhibited evidence of bot automation. Of the fraudulent cases, 53.9% (138/256) provided a duplicate or unusual response to one or more open-ended items and 52.0% (133/256) exhibited evidence of inattention. CONCLUSIONS: Research findings from several disciplines suggest studies in which research participants are recruited through social media are susceptible to data quality issues. Opportunistic individuals who use virtual private servers to fraudulently complete research surveys for profit may contribute to low-quality data. Strategies to preserve data integrity following research participant recruitment through social media are limited. Development and testing of novel strategies to prevent and detect fraud is a research priority.
