Patterns of self-reported symptoms in pancreatic cancer patients receiving chemoradiation

Evaluation of the Effect of Self-Efficacy on Symptoms in Gastrointestinal Cancer Patients

Objective: The incidence of gastrointestinal cancer is increasing day by day and is among the highest 10 cancer types in the world. This study was conducted to evaluate the effects of self-efficacy of patients with gastrointestinal system cancer on symptom clusters. Methods: This cross-sectional study was conducted with 105 patients treated for gastrointestinal system cancer in a hospital located in the south of Turkey. In the study, patients over 18 years of age without hearing or speech impairment were included. To determine symptom clusters, Latent Profile Analysis and comparison of self-efficacy scale items by symptom clusters were performed with Chi-square, ANOVA, and Kruskal Wallis test. Results: The mean age of the patients was 58.83 ± 13.1 years; of the patients, 37.1% had colon ca, 21.9% had rectum ca. The patients had higher mean scores of fatigue, pain, feeling distressed, feeling sad, dry mouth, sleep disturbance, loss of appetite and nausea in the last week. The patients had higher mean scores of fatigue, pain, feeling distressed, feeling sad, dry mouth, sleep disturbance, loss of appetite and nausea in the last week. Three symptom clusters were determined by latent profile analysis; high, moderate, mild. It was determined that the level of self-efficacy was high in the symptom cluster which is low symptom severity and number of symptoms (p < .05). Conclusion: The number and the severity of symptoms are lower in patients with high self-efficacy perceptions.

Index Symptoms and Prognosis Awareness of Patients With Pancreatic Cancer: A Multi-Site Palliative Care Collaborative

BACKGROUND

Pancreatic cancer has a poor 5-year survival and carries significant morbidity. Pain is a commonly studied symptom in pancreatic cancer; however, few studies examine the frequency of multiple patient-reported symptoms. Our aim is to ascertain patient-reported symptom burden at initial consultation with a palliative care provider and compare patient prognostic awareness to provider estimation of prognosis.

METHODS

Data were extracted from the standardized Quality Data Collection Tool (QDACT). Adults with pancreatic cancer seen by a palliative care provider were included. Descriptive statistics were used to describe demographic features, symptom prevalence and burden, as well as assess patient prognosis awareness defined by congruence or incongruence with provider estimated prognosis.

RESULTS

285 patients were included in our analysis. The average age was 68 years (SD: 12.4), 87.2% were white, 50% male. The mean number of moderate/severe symptoms was 2.6 (SD: 2) out of 9 symptoms. Tiredness (66.7%), appetite (64.5%) and pain (46.2%) had the highest rates of moderate/severe symptom burden. Patients with a prognosis of 1-6 months had the lowest proportion of congruence with provider estimation (56.5%).

CONCLUSION

Our study suggests targets to improve patient-centered care of pancreatic cancer. Patients commonly have multiple symptoms that are moderate/severe at time of palliative care referral. While pain has been well-reported, tiredness and decreased appetite are more prevalent at initial visit. This emphasizes the importance of assessing multiple symptoms and working closely with palliative care for early referral. Overall, one third of patient prognosis estimates differed from the provider assessment of prognosis. Our data support the importance of early referral to palliative care to manage symptoms and better prepare patients for end-of-life care.

Tumor Growth Suppression of Pancreatic Cancer Orthotopic Xenograft Model by CEA-Targeting CAR-T Cells

Chimeric antigen receptor engineered T cell (CAR-T) therapy has high therapeutic efficacy against blood cancers, but it has not shown satisfactory results in solid tumors. Therefore, we examined the therapeutic effect of CAR-T therapy targeting carcinoembryonic antigen (CEA) in pancreatic adenocarcinoma (PDAC). CEA expression levels on the cell membranes of various PDAC cell lines were evaluated using flow cytometry and the cells were divided into high, medium, and low expression groups. The relationship between CEA expression level and the antitumor effect of anti-CEA-CAR-T was evaluated using a functional assay for various PDAC cell lines; a significant correlation was observed between CEA expression level and the antitumor effect. We created orthotopic PDAC xenograft mouse models and injected with anti-CEA-CAR-T; only the cell line with high CEA expression exhibited a significant therapeutic effect. Thus, the therapeutic effect of CAR-T therapy was related to the target antigen expression level, and the further retrospective analysis of pathological findings from PDAC patients showed a correlation between the intensity of CEA immunostaining and tumor heterogeneity. Therefore, CEA expression levels in biopsies or surgical specimens can be clinically used as biomarkers to select PDAC patients for anti-CAR-T therapy.

Evaluation of a Clinic-Based Exercise Program in Patients with Pancreatic Cancer Undergoing Nonsurgical Treatment

INTRODUCTION

Evidence regarding the role of exercise in pancreatic cancer (PanCa) is limited and is derived exclusively under tightly controlled research conditions. This study aimed to quantify adherence, adverse events, and changes in physical and psychological outcomes in any patients with PanCa referred to undertake exercise during nonsurgical treatment.

METHODS

The study involved 22 patients with localized or metastatic PanCa undertaking a clinic-based exercise program during chemotherapy or chemoradiotherapy. The program included supervised aerobic and resistance exercise undertaken twice weekly for 12 wk and a 12-wk follow-up with supervised exercise optional dependent on patient preference and condition. Patients were monitored for adherence and adverse events. Objective and patient-reported outcomes were assessed at baseline, 12 wk, and 24 wk.

RESULTS

A total of 251 sessions were attended by 19 patients over the first 12 wk (attendance rate, 55%). Complete case analyses indicated significant ( P < 0.05) improvements in functional ability (5.2%-17.2%), muscle strength (16.9%-25.1%), and static balance (6.8%). There were no significant changes in body composition or patient-reported outcomes except for sleep quality, which deteriorated; however, at an individual level, several patients had clinically relevant improvements in cancer-related fatigue and quality of life. Patients who continued with supervised exercise to week 24 largely preserved improvements in functional ability, muscle strength, and static balance. No serious adverse events resulted from the exercise program.

CONCLUSIONS

Individualized, supervised aerobic and resistance exercise in a clinic-based setting appears to be safe and may improve or maintain physical and psychological health in patients with PanCa undergoing nonsurgical treatment.

Pancreatic ductal adenocarcinoma: Emerging therapeutic strategies

The seventh leading cause of cancer-related death globally, pancreatic ductal adenocarcinoma (PDAC) involves the exocrine pancreas and constitutes greater than 90% of all pancreatic cancers. Surgical resection in combination with systemic chemotherapy with or without radiation remains the mainstay of treatment and the only potentially curative treatment option. While there has been improvement in systemic chemotherapy, long-term survival among patients with PDAC remains poor. Improvement in the understanding of tumorigenesis, genetic mutations, the tumor microenvironment (TME), immunotherapies, as well as targeted therapies continued to drive advances in PDAC treatment. We herein review the TME, genetic landscape, as well as various metabolic pathways associated with PDAC tumorigenesis relative to emerging therapies.

Immunotherapy in Combination with Well-Established Treatment Strategies in Pancreatic Cancer: Current Insights

Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer and fourth most common cause of death in developed countries. Despite improved survival rates after resection combined with adjuvant chemotherapy or neoadjuvant chemotherapy, recurrence still occurs in a high percentage of patients within the first 2 years after resection. Immunotherapy aims to improve antitumor immune responses and reduce toxicity providing a more specific, targeted therapy compared to chemotherapy and has been proved an efficient therapeutic tool for many solid tumors. In this work, we present the latest advances in PDAC treatment using a combination of immunotherapy with other interventions such as chemotherapy and/or radiation both at neoadjuvant and adjuvant setting. Moreover, we outline the role of the tumor microenvironment as a key barrier to immunotherapy efficacy and examine how immunotherapy biomarkers may be used to detect immunotherapy’s response.

Symptom Clusters and Quality of Life in Gastric Cancer Patients Receiving Chemotherapy

CONTEXT

Although gastric cancer is one of the most common tumors worldwide, there is little knowledge about symptom clusters and quality of life (QoL) in this population.

OBJECTIVES

The objectives were to identify the symptom clusters in gastric cancer patients receiving chemotherapy, and explore their effects on QoL.

METHODS

Gastric cancer patients receiving chemotherapy were recruited. Data were collected using the Memorial Symptom Assessment Scale Short Form, the Functional Assessment of Cancer Therapy-Gastric and the self-designed General Information Evaluation Form. The symptom clusters were extracted through the exploratory factor analysis. The influencing factors of symptom clusters and their effects on QoL were identified using multiple linear regression analysis.

RESULTS

A total of 322 participants were enrolled from three medical centers. Five factors were identified in this exploratory factor analysis based on symptom prevalence, namely fatigue related symptom cluster, epithelial symptom cluster, neurologic symptom cluster, malnutrition related symptom cluster and psychological symptom cluster (χ² = 31.470, P < 0.05). The affecting factors across symptom clusters and QoL subscales were relatively stable, but also different. Generally, fatigue related symptom cluster, malnutrition related symptom cluster and psychological symptom cluster demonstrated significantly negative effects on all aspects of QoL except social well being.

CONCLUSION

Five symptom clusters were identified in gastric cancer patients receiving chemotherapy in mainland China. The symptom clusters negatively contributed to the variance in all aspects of QoL except social well being. Further studies should examine interventions for symptom clusters, their influencing factors, and their effects on improving QoL.

Liquid Biopsy as a Prognostic and Theranostic Tool for the Management of Pancreatic Ductal Adenocarcinoma

Pancreatic ductal adenocarcinomas (PDAC) represent one of the deadliest cancers worldwide. Survival is still low due to diagnosis at an advanced stage and resistance to treatment. Herein, we review the main types of liquid biopsy able to help in both prognosis and adaptation of treatments.

Tumor-mutation burden as a marker for immunotherapy of pancreatic cancer: the case report and literature review

Pancreatic cancer is digestive cancer with limited therapeutic options and a poor outcome. Pancreatic cancer has a high mortality rate, with a 5-year survival rate of less than 5%. The median survival after metastasis of the disease is less than 6 months. Studies have revealed that the standard treatment, including palliative chemotherapy or immunotherapy, is not significantly effective for pancreatic cancer. Herein, we report a case of pancreatic cancer who benefited from a combination of anti-PD-1 immunotherapy and chemotherapy.

Two Antibody-Guided Lactic-co-Glycolic Acid-Polyethylenimine (LGA-PEI) Nanoparticle Delivery Systems for Therapeutic Nucleic Acids

We previously reported a new polymer, lactic-co-glycolic acid-polyethylenimine (LGA-PEI), as an improved nanoparticle (NP) delivery for therapeutic nucleic acids (TNAs). Here, we further developed two antibody (Ab)-conjugated LGA-PEI NP technologies for active-targeting delivery of TNAs. LGA-PEI was covalently conjugated with a single-chain variable fragment antibody (scFv) against mesothelin (MSLN), a biomarker for pancreatic cancer (PC), or a special Ab fragment crystallizable region-binding peptide (FcBP), which binds to any full Ab (IgG). TNAs used in the current study included tumor suppressor microRNA mimics (miR-198 and miR-520h) and non-coding RNA X-inactive specific transcript (XIST) fragments; green fluorescence protein gene (GFP plasmid DNA) was also used as an example of plasmid DNA. MSLN scFv-LGA-PEI NPs with TNAs significantly improved their binding and internalization in PC cells with high expression of MSLN in vitro and in vivo. Anti-epidermal growth factor receptor (EGFR) monoclonal Ab (Cetuximab) binding to FcBP-LGA-PEI showed active-targeting delivery of TNAs to EGFR-expressing PC cells.

Symptom Burden of Patients with Advanced Pancreas Cancer (APC): A Provincial Cancer Institute Observational Study

Patients with advanced pancreatic cancer (APC) experience many disease-related symptoms. ESAS-r measures the severity of 9 symptom domains and has been validated for use in the ambulatory oncology setting. We aimed to describe symptom burden at baseline for patients with APC treated with modern chemotherapy (CT), and to determine whether symptom burden at baseline is prognostic. Patients diagnosed with APC between 2012-2016, treated with ≥1 cycle of CT, who completed ≥1 ESAS-r were identified. Descriptive statistics were used to report symptom burden and common moderate-to-severe symptoms. A joint model was used to describe the trajectory of ESAS-r during follow-up while controlling for death. Multivariable Cox regression was used to identify independent predictors of death. Of 123 patients identified, the median age was 65 and 61% had metastatic disease. The median baseline ESAS-r total symptom distress score (TSDS) was 24. A total of 86% of patients had at least one symptom score of ≥4 at baseline, with the most common being: fatigue, nausea, anxiety, and shortness of breath. Median overall survival was 10.2 months. Baseline TSDS was not predictive for worse survival in the era of modern CT. Patients with APC have a high burden of cancer-associated symptoms and a high prevalence of moderate-to-severe symptoms. Early intervention has the potential to improve quality of life in this group of patients and should be investigated.

Exercise Medicine in the Management of Pancreatic Cancer: A Systematic Review

ABSTRACT

The aim of this study was to examine the health-related effects of exercise in patients with pancreatic cancer (PanCa) through a systematic review of current evidence. Studies were obtained through searching PubMed, Web of Science, PsycINFO, Embase, CINAHL Plus, and Cochrane Library databases with additional hand searches. All intervention-based studies were included if it involved (1) adult patients with PanCa, (2) exercise training, and (3) findings in quality of life, cancer-related fatigue, psychological distress, and physical function. The review protocol was registered in PROSPERO: CRD42020154684. Seven trials described in 9 publications were included consisting of 201 patients with early-stage and advanced PanCa. Participants were required to perform supervised and/or home-based, low- to moderate-intensity resistance and/or aerobic exercise for 12 to 35 weeks or duration of neoadjuvant therapy. There were no exercise-related adverse events with a reported retention rate of 71% to 90% and exercise attendance of 64% to 96%. The programs were consistently associated with improvements in cancer-related fatigue, psychological distress, and physical function, with mixed effects on quality of life. Exercise training seems to be safe and feasible and may have a beneficial effect on various physical and psychological outcomes in patients with PanCa. Further work with rigorous study designs is required to consolidate and advance current findings.

Symptom Burden of Nonresected Pancreatic Adenocarcinoma: An Analysis of 10,753 Patient-Reported Outcome Assessments

OBJECTIVES

Pancreatic adenocarcinoma (PAC) is a debilitating disease. We sought to analyze symptom burden and trajectories after diagnosis of PAC and identify predictors of severe symptoms for nonresected patients.

METHODS

This was a retrospective review of linked administrative health care databases examining patients with PAC not undergoing resection. Primary outcome was severe patient-reported symptoms (Edmonton Symptom Assessment System ≥7). Multivariable modified Poisson regression models were used to identify factors associated with reporting severe symptoms.

RESULTS

A total of 10,753 symptom assessments from 2168 patients were analyzed. The median age was 67 years, and 47% were female; median survival was 7 months. Most common severe symptoms were tiredness (54.7%), anorexia (53.6%), overall impaired well-being (45.3%), and drowsiness (37.1%). Severity of symptoms decreased 1 month after diagnosis and plateaued 4 months after diagnosis. Female sex, comorbidities, and older age were associated with reporting severe symptoms; recent radiation treatment and residence in a rural community were associated with reporting less severe symptoms.

CONCLUSIONS

The prevalence of severe symptoms in patients with nonresected PAC was high, but potentially modifiable. We identified vulnerable groups of patients that may benefit from focused interventions. This information is important for patient counseling and design of supportive care strategies.

Immunotherapy for pancreatic cancer: A 2020 update

Pancreatic adenocarcinoma (PAC) is associated with extremely poor prognosis and remains a lethal malignancy. The main cure for PAC is surgical resection. Further treatment modalities, such as surgery, chemotherapy, radiotherapy and other locoregional therapies provide low survival rates. Currently, many clinical trials seek to assess the efficacy of immunotherapeutic strategies in PAC, including immune checkpoint inhibitors, cancer vaccines, adoptive cell transfer, combinations with other immunotherapeutic agents, chemoradiotherapy or other molecularly targeted agents; however, none of these studies have shown practice changing results. There seems to be a synergistic effect with increased response rates when a combinatorial approach of immunotherapy in conjunction with other modalities is being exploited. In this review, we illustrate the current role of immunotherapy in PAC.

Are population-based patient-reported outcomes associated with overall survival in patients with advanced pancreatic cancer?

BACKGROUND

Advanced pancreatic cancer (APC) patients often have substantial symptom burden. In Ontario, patients routinely complete the Edmonton Symptom Assessment Scale (ESAS), which screens for nine symptoms (scale: 0-10), in cancer clinics. We explored the association between baseline patient-reported outcomes, via ESAS, and overall survival (OS).

METHODS

Advanced pancreatic cancer patients with ESAS records prior to receiving publicly funded drugs from November 2008 to March 2016 were retrospectively identified from Cancer Care Ontario's administrative databases. We examined three composite ESAS scores: total symptom distress score (TSDS: 9 symptoms), physical symptom score (PHS: 6/9 symptoms), and psychological symptom score (PSS: 2/9 symptoms); Composite scores greater than defined thresholds (TSDS ≥36, PHS ≥24, PSS ≥8) were considered as high symptom burden. Crude OS was assessed using Kaplan-Meier method. Hazard ratios (HRs) were assessed using multivariable Cox models. Analysis was repeated in a sub-cohort with Eastern Cooperative Oncology Group (ECOG) status and metastasis.

RESULTS

We identified 2199 APC patients (mean age 64 years, 55% male) with ESAS records prior to receiving chemotherapy. Crude median survival was 4.5 and 7.3 months for high and low TSDS, respectively. High TSDS was associated with lower OS (HR = 1.47, 95% CI: 1.33, 1.63). In the sub-cohort (n = 393) with ECOG status and metastasis, high TSDS was also associated with lower OS (HR = 1.34, 95% CI: 1.04, 1.73). Similar trends were observed for PHS and PSS.

CONCLUSIONS

Higher burden of patient-reported outcome was associated with reduced OS among APC patients. The effect was prominent after adjusting for ECOG status.

Stability of Symptom Clusters in Patients With Gastrointestinal Cancers Receiving Chemotherapy

CONTEXT

Limited evidence suggests that patients with gastrointestinal (GI) cancers receiving chemotherapy (CTX) experience an average of 13 co-occurring symptoms. An alternative to counting symptoms is to evaluate for symptom clusters.

OBJECTIVES

In a sample of patients with GI cancers receiving CTX (n = 399), we evaluated the occurrence, severity, and distress of 38 symptoms in the week before patients' second or third cycle of CTX (Time 1 [T1]), approximately one week after CTX (Time 2 [T2]), and approximately two weeks after CTX (Time 3 [T3]); evaluated for differences in the number and types of symptom clusters at each of these three assessments using ratings of occurrence, severity, and distress; and evaluated for changes in symptom clusters over time.

METHODS

Modified version of the Memorial Symptom Assessment Scale collected data on 38 common symptoms. Exploratory factor analyses were used to create the symptom clusters.

RESULTS

Five distinct symptom clusters were identified across the three symptom dimensions and the three assessments (i.e., psychological, CTX-related, weight change, GI, and epithelial). Psychological, CTX-related, and weight change clusters were relatively stable across all three symptom dimensions and time. Across all three symptom dimensions, GI cluster was identified only at T1 and epithelial cluster was identified at T2 and T3.

CONCLUSION

The number and types of symptom clusters appear to be relatively stable over time and across the symptom dimensions. Ongoing assessment and management of these clusters is warranted across the entire course of CTX. The underlying mechanism for these clusters warrants investigation.

Population-Level Symptom Assessment Following Pancreaticoduodenectomy for Adenocarcinoma

Importance

Postoperative morbidity associated with pancreaticoduodenectomy (PD) for pancreatic adenocarcinoma (PA) remains as high as 70%. However, to our knowledge, few studies have examined quality of life in this patient population.

Objective

To identify symptom burden and trajectories and factors associated with high symptom burden following PD for PA.

Design, Setting, and Participants

This population-based cohort study of patients undergoing PD for PA diagnosed between 2009 and 2015 linked population-level administrative health care data to routinely prospectively collected Edmonton Symptom Assessment System (ESAS) scores from 2009 to 2015, with a data analysis undertaken in 2018.

Exposures

Baseline characteristics, including age, sex, income quintile, rurality, immigration status, and comorbidity burden, as well as treatment characteristics, including year of surgery and receipt of chemotherapy.

Main Outcome and Measures

The outcome of interest was moderate to severe symptoms (defined as ESAS ≥4) for anxiety, depression, drowsiness, lack of appetite, nausea, pain, shortness of breath, tiredness, and impaired well-being. The monthly prevalence of moderate to severe symptoms was presented graphically for each symptom. Multivariable regression models identified factors associated with the reporting of moderate to severe symptoms.

Results

We analyzed 6058 individual symptom assessments among 615 patients with PA who underwent resection (285 women [46.3%]) with ESAS data. Tiredness (443 [72%]), impaired well-being (418 [68%]), and lack of appetite (400 [65%]) were most commonly reported as moderate to severe. The proportion of patients with moderate to severe symptoms was highest immediately after surgery (range, 14%-66% per symptom) and decreased over time, stabilizing around 3 months (range, 8%-42% per symptom). Female sex, higher comorbidity, and lower income were associated with a higher risk of reporting moderate to severe symptoms. Receipt of adjuvant chemotherapy was not associated with the risk of moderate to severe symptoms.

Conclusions and Relevance

There is a high prevalence of symptoms following PD for PA, with improvement over the first 3 months following surgery. In what to our knowledge is the largest cohort reporting on symptom burden for this population, we have identified factors associated with symptom severity. These findings will aid in managing patients' perioperative expectations and designing strategies to improve targeted symptom management.

Symptom Clusters in Patients With Gastrointestinal Cancers Using Different Dimensions of the Symptom Experience

CONTEXT

Patients with gastrointestinal (GI) cancers undergoing chemotherapy (CTX) experience multiple cooccurring symptoms.

OBJECTIVES

The aim of this study was to describe the occurrence, severity, and distress of 38 symptoms and to identify symptom clusters based on three symptom dimensions (i.e., occurrence, severity, and distress) in patients with GI cancers receiving CTX (n = 399). We compared whether the numbers and types of symptom clusters differed based on the dimension of the symptom experience used to create the clusters.

METHODS

A modified version of the Memorial Symptom Assessment Scale was used to assess the occurrence, severity, and distress of 38 symptoms before the initiation of the patient's next dose of CTX. Exploratory factor analysis was used to determine the symptom clusters.

RESULTS

These patients experienced 13.0 (±7.1) symptoms before their second or third dose of CTX. For all three symptom dimensions, four symptom clusters were identified, namely psychological distress, CTX-related, GI, and weight change. The number and types of symptom clusters were relatively similar using all three symptom dimensions. However, some variability was found in the specific symptoms within each of the clusters.

CONCLUSION

Our findings suggest that patients with GI cancers experience multiple cooccurring symptoms. Consistent with previous studies of patients with a variety of cancer diagnoses, psychological and GI clusters are common. Clinicians need to assess for and tailor interventions for these symptom clusters.

Symptom Clusters in Patients With Pancreatic Cancer Undergoing Surgical Resection: Part II

OBJECTIVES

To explore the relationship between 16 symptom clusters (SCs), clinical and demographic influencing factors, and clinical outcomes over time in patients with pancreatic cancer (PC) undergoing surgical resection.

SAMPLE & SETTING

143 patients with stage II PC undergoing surgical resection were recruited to participate in this longitudinal, exploratory study conducted at Thomas Jefferson University Hospital, a National Cancer Institute-designated cancer center.

METHODS & VARIABLES

Quality of life was measured preoperatively and at three, six, and nine months postoperatively. Statistical methods included simple linear and Cox proportional hazard regression.

RESULTS

Preoperative pain was significantly associated with the pain-gastrointestinal SC, and preoperative worry was significantly associated with the mood SC. The strongest negative association with emotional well-being across all study time points was found with the preoperative mood SC. The insomnia-digestive problems SC and the nutritional problems SC demonstrated a trend toward poor survival.

IMPLICATIONS FOR NURSING

Findings provide evidence that preoperative worry and pain are associated with SC severity and that SCs may have a detrimental effect on quality of life and survival in patients with PC undergoing surgical resection.

Symptom Clusters in Patients With Pancreatic Cancer Undergoing Surgical Resection: Part I

OBJECTIVES

To describe patient-reported symptoms and symptom clusters in patients with pancreatic cancer (PC) undergoing surgical resection.

SAMPLE & SETTING

143 patients with stage II PC undergoing surgical resection alone or with subsequent adjuvant chemoradiation or chemotherapy were recruited to participate in a nested, longitudinal, exploratory study through convenience sampling techniques from Thomas Jefferson University Hospital, a National Cancer Institute-designated cancer center.

METHODS & VARIABLES

The Functional Assessment in Cancer Therapy-Hepatobiliary questionnaire was used to assess 17 PC symptoms preoperatively and at three, six, and nine months postoperatively. Exploratory and confirmatory factor analyses were used to identify symptom clusters.

RESULTS

Fatigue, trouble sleeping, poor appetite, trouble digesting food, and weight loss were consistently reported as the most prevalent and severe symptoms. Sixteen distinct symptom clusters were identified within nine months of surgery. Four core symptom clusters persisted over time.

IMPLICATIONS FOR NURSING

Findings may be used to provide anticipatory patient and family guidance and to inform clinical assessments of symptoms and symptom clusters in this population.

Update on Prevalence of Pain in Patients With Cancer: Systematic Review and Meta-Analysis

CONTEXT

Cancer pain has a severe impact on quality of life and is associated with numerous psychosocial responses. Recent studies suggest that treatment of cancer pain has improved during the last decade.

OBJECTIVES

The aim of this review was to examine the present status of pain prevalence and pain severity in patients with cancer.

METHODS

A systematic search of the literature published between September 2005 and January 2014 was performed using the databases PubMed, Medline, Embase, CINAHL, and Cochrane. Articles in English or Dutch that reported on the prevalence of cancer pain in an adult population were included. Titles and abstracts were screened by two authors independently, after which full texts were evaluated and assessed on methodological quality. Study details and pain characteristics were extracted from the articles with adequate study quality. Prevalence rates were pooled with meta-analysis; meta-regression was performed to explore determinants of pain prevalence.

RESULTS

Of 4117 titles, 122 studies were selected for the meta-analyses on pain (117 studies, n = 63,533) and pain severity (52 studies, n = 32,261). Pain prevalence rates were 39.3% after curative treatment; 55.0% during anticancer treatment; and 66.4% in advanced, metastatic, or terminal disease. Moderate to severe pain (numerical rating scale score ≥5) was reported by 38.0% of all patients.

CONCLUSION

Despite increased attention on assessment and management, pain continues to be a prevalent symptom in patients with cancer. In the upcoming decade, we need to overcome barriers toward effective pain treatment and develop and implement interventions to optimally manage pain in patients with cancer.

Rationale and design of the Adapted Physical Activity in advanced Pancreatic Cancer patients (APACaP) GERCOR (Groupe Coopérateur Multidisciplinaire en Oncologie) trial: study protocol for a randomized controlled trial

BACKGROUND

Exercise during chemotherapy is a promising strategy to reduce fatigue and improve health-related quality of life (HRQoL). It has been shown to be feasible and efficient in various cancers, including advanced-stage cancers. Effects of physical activity have never been explored in advanced pancreatic ductal adenocarcinoma (PDAC). We aim to evaluate the effects of an exercise intervention in this setting.

METHODS

This randomized, national, multicenter, interventional study will examine the effectiveness of an unsupervised, home-based, 16-week adapted physical activity (APA) program. Specificities of advanced PDAC for the implementation of the APA program will be taken into account (healthy volunteer as physical activity partner instead of patient groups, nutritional management). The main inclusion criteria are: patients with histologically confirmed, unresectable PDAC; scheduled for chemotherapy; performance status 0-2; age ≥ 18; and physical activity partner. In total, 200 patients will be randomized into either the APA program (aerobic and resistance exercises) in addition to usual care (including chemotherapy at the investigator's choice), or usual care. The primary objective will be the effect on fatigue (Multidimensional Fatigue Inventory, MFI-20) and HRQoL (European Organization for Research and Treatment of Cancer-Quality of Life-C30 questionnaire, EORTC-QLQ-C30; co-primary endpoint) at week 16. As secondary objectives, the effects of the exercise intervention on pain, anxiety, depression, nutritional status, insulin resistance, tolerance of chemotherapy, survival, and adherence to the APA program will be evaluated.

DISCUSSION

Patients with advanced PDAC are strongly affected by fatigue, and are thus likely to benefit from an exercise intervention. Moreover, exercise may have a potential beneficial effect on tumor outcome by reducing insulin resistance and insulin/insulin-like growth factor-1 (IGF-1) secretion. However, an exercise intervention may appear challenging due to multiple PDAC-related symptoms such as fatigue, depression, pain, and denutrition. We hypothesize that an APA program taking into account specific characteristics of PDAC may improve symptoms and HRQoL. If demonstrated to be feasible and effective, such APA programs will be systematically proposed to patients with advanced PDAC in addition to usual care.

A literature synthesis of symptom prevalence and severity in persons receiving active cancer treatment

PURPOSE

Patients with cancer experience acute and chronic symptoms caused by their underlying disease or by the treatment. While numerous studies have examined the impact of various treatments on symptoms experienced by cancer patients, there are inconsistencies regarding the symptoms measured and reported in treatment trials. This article presents a systematic review of the research literature of the prevalence and severity of symptoms in patients undergoing cancer treatment.

METHODS

A systematic search for studies of persons receiving active cancer treatment was performed with the search terms of "multiple symptoms" and "cancer" for studies involving patients over the age of 18 years and published in English during the years 2001 to 2011. Search outputs were reviewed independently by seven authors, resulting in the synthesis of 21 studies meeting criteria for generation of an Evidence Table reporting symptom prevalence and severity ratings.

RESULTS

Data were extracted from 21 multi-national studies to develop a pooled sample of 4,067 cancer patients in whom the prevalence and severity of individual symptoms was reported. In total, the pooled sample across the 21 studies was comprised of 62% female, with a mean age of 58 years (range 18 to 97 years). A majority (62%) of these studies assessed symptoms in homogeneous samples with respect to tumor site (predominantly breast and lung cancer), while 38% of the included studies utilized samples with mixed diagnoses and treatment regimens. Eighteen instruments and structured interviews were including those measuring single symptoms, multi-symptom inventories, and single symptom items drawn from HRQOL or health status measures. The MD Anderson Symptom Inventory was the most commonly used instrument in the studies analyzed (n = 9 studies; 43%), while the Functional Assessment of Cancer Therapy, Hospital Anxiety and Depression Subscale, Medical Outcomes Survey Short Form-36, and Symptom Distress Scale were each employed in two studies. Forty-seven symptoms were identified across the 21 studies which were then categorized into 17 logical groupings. Symptom prevalence and severity were calculated across the entire cohort and also based upon sample sizes in which the symptoms were measured providing the ability to rank symptoms.

CONCLUSIONS

Symptoms are prevalent and severe among patients with cancer. Therefore, any clinical study seeking to evaluate the impact of treatment on patients should consider including measurement of symptoms. This study demonstrates that a discrete set of symptoms is common across cancer types. This set may serve as the basis for defining a "core" set of symptoms to be recommended for elicitation across cancer clinical trials, particularly among patients with advanced disease.

Health Is Belonging: Lived Experiences during Recovery after Pancreaticoduodenectomy

The aim of this study was to explore the lived experience of the symptoms, health, and illness reported by patients recovering after pancreaticoduodenectomy ad modum Whipple due to pancreatic or periampullary cancer. Thirteen patients with pancreatic or periampullary cancer who underwent pancreaticoduodenectomy ad modum Whipple between 2006 and 2008 were interviewed during postoperative recovery. Data were analysed using the phenomenological-hermeneutic method. The structural analysis of patient experiences revealed that recovery after pancreaticoduodenectomy was described as recapturing everyday life, being healthy, and looking to the future. Participants experienced symptoms but did not dwell on them, instead they stated that their general health was good. They strived to regain their former precancer selves and be a part of as well as contribute to the social context. Overall, the participants' view of the future was positive, and improvement in their health generated further confidence and encouragement. This study suggests that persons recovering from pancreaticoduodenectomy ad modum Whipple due to a pancreatic or periampullary tumour experience health despite postoperative symptoms. They manage their symptoms by means of different strategies and express a positive view of the future. Nurses working with such patients should adopt a person-centred approach focusing on patient perspectives, participation, and possibilities.

Relationships among body mass index, longitudinal body composition alterations, and survival in patients with locally advanced pancreatic cancer receiving chemoradiation: a pilot study

CONTEXT

In pancreatic cancer, the presence of obesity or weight loss is associated with higher mortality.

OBJECTIVES

To explore the relationships among body mass index, longitudinal body composition alterations, and clinical outcomes in pancreatic cancer patients.

METHODS

Records of 41 patients with inoperable locally advanced pancreatic cancer who participated in a prospective chemoradiation study were reviewed. Body composition was analyzed from two sets of computed tomography images obtained before and after radiation treatment (median interval 104 days).

RESULTS

Median age was 59 years and 56% of patients were female. Twenty-four (59%) patients were either overweight (22%) or obese (37%). Sarcopenia was present in 26 (63%) patients. At follow-up, weight loss was experienced by 33 (81%) patients. The median losses (%) before and after treatment were weight 5% (P<0.001), skeletal muscle (SKM) 4% (P=0.003), visceral adipose tissue (VAT) 13% (P<0.001), and subcutaneous adipose tissue 11% (P=0.002). SKM loss positively correlated with age (P=0.03), baseline body mass index (P<0.001), and VAT (P=0.04) index. Obese patients experienced higher losses in weight (P=0.009), SKM (P=0.02), and VAT (P=0.02). Median survival was 12 months. In univariate analysis, age, baseline obesity, sarcopenic obesity, and losses (%) in weight, SKM, and VAT were associated with worse survival. In multivariate analysis, only age (hazard ratio=1.033, P=0.04) and higher VAT loss (hazard ratio=2.6 and P=0.03) remained significant.

CONCLUSION

Our preliminary findings suggest that obese patients experience higher losses in weight, SKM, and VAT, which may contribute to poorer survival in these patients.

Screening for depression, sleep-related disturbances, and anxiety in patients with adenocarcinoma of the pancreas: a preliminary study

Purpose. Screening for depression, sleep-related disturbances, and anxiety in patients with diagnosed adenocarcinoma of the pancreas. Materials and Methods. Patients were evaluated at initial consultation and subsequent visits at the multidisciplinary pancreatic cancer clinic at our University Cancer Center. Cross-sectional and longitudinal psychosocial distress was assessed utilizing Personal Health Questionnaire 9 (PHQ9) to screen for depression and monitor symptoms, the Penn State Worry Questionnaire (PSWQ) for generalized anxiety, and the University of Michigan Sleep Questionnaire to monitor sleep symptoms. Results. Twenty-two patients diagnosed with pancreatic cancer participated during the 6-month pilot study with longitudinal followup for thirteen patients. In this study, mild-to-moderate depressive symptoms, anxiety, and potential sleep problems were common. The main finding of the study was 23% of the patients who were part of this pilot project screened positive for moderately severe major depressive symptoms, likely anxiety disorder or a potential sleep disorder during the study. One patient screened positive for moderately severe depressive symptoms in longitudinal followup. Conclusions. Depression, anxiety, and sleep problems are evident in patients with pancreatic cancer. Prospective, longitudinal studies, with larger groups of patients, are needed to determine if these comorbid symptoms impact outcome and clinical course.

A progressive postresection walking program significantly improves fatigue and health-related quality of life in pancreas and periampullary cancer patients

BACKGROUND

As patients with pancreas and periampullary cancer (PPC) experience improved survival rates and longevity, the focus shifts toward living life while surviving cancer. Fatigue is the most commonly reported symptom in all cancer patients. Exercise has been found to effectively decrease fatigue levels and improve physical functioning in cancer patients.

STUDY DESIGN

One hundred two patients with resected PPC consented to participate in this study and were randomized to either an intervention group (IG) or a usual care group (UCG). Subjects completed visual analog scales, the FACIT-Fatigue Scale and the Short Form-36v2 after surgery and again 3 to 6 months after hospital discharge.

RESULTS

Patients in the IG and UCG were comparable with regard to demographics, comorbidities, cancer type and staging, type of resection, preoperative fatigue and pain levels, adjuvant therapy, and baseline walking distance. Patients in the IG had significantly improved scores on the FACIT-Fatigue Scale at study completion, improved fatigue and pain scores, as well as overall physical functioning and mental health composite scores. At study completion, participants in the IG were walking twice as far and were significantly more likely to have continued walking or another form of exercise as compared with the UCG. Using hierarchical cluster analysis, 3 mutually exclusive symptom groupings were identified in the cohort. Kaplan-Meier survival analysis did not indicate an overall survival benefit for the IG.

CONCLUSIONS

This is the first prospective, randomized controlled trial to report that participation in a home walking program confers a significant benefit in resected PPC patients with regard to fatigue levels, physical functioning, and health-related quality of life.

Docetaxel- and 5-FU-concurrent radiotherapy in patients presenting unresectable locally advanced pancreatic cancer: a FNCLCC-ACCORD/0201 randomized phase II trial's pre-planned analysis and case report of a 5.5-year disease-free survival

Background

To explore possible improvement in the treatment of locally advanced pancreatic carcinoma (LAPC) we performed a randomized, non-comparative phase II study evaluating docetaxel - plus either daily continuous 5 FU or weekly cisplatin concurrent to radiotherapy. We report here the results of the docetaxel plus 5 FU regimen stopped according to the interim analysis. The docetaxel plus cisplatin arm was continued.

Methods

Forty (40) chemotherapy-naive patients with unresectable LAPC were randomly assigned (1:1) to either continuous fluorouracil (5-FU) 200 mg/m²/day (protracted IV) and docetaxel (DCT) 20 mg/m²/week or DCT 20 mg/m² and cisplatin (CDDP) 20 mg/m², plus concurrent radiotherapy for a period of 6 weeks. The radiation dose to the primary tumor was 54 Gy in 30 fractions. The trial's primary endpoint was the 6-month crude non-progression rate (NPR). Secondary endpoints were tolerance, objective response rate, and overall survival. Accrual was to be stopped if at 6 months more than 13 disease progressions were observed in 20 patients.

Results

Eighteen (18) progressions occurred at 6 months in the 5-FU-DCT arm. Six-month NPR was 10% (95%CI: 0-23). Six and 12-month survivals were 85% (95%CI: 64-95) and 40% (95%CI: 22-61); median overall survival was 10.1 months. Median progression-free survival was 4.3 months. We report the case of one patient who was amenable to surgery and has been in complete response (CR) for 5.5 years. Toxicities grade ≥ 3 were reported in 75% of patients; no treatment-related death occurred. Severe toxicities were mainly vomiting (35%), abdominal pain (10%) and fatigue (10%).

Conclusions

Combination of 5-FU, docetaxel and radiotherapy has inadequate efficacy in the treatment of LAPC despite good tolerance for the 5-FU-DCT regimen.

Relationship between mood disturbance and sleep quality in oncology outpatients at the initiation of radiation therapy

PURPOSE OF THE RESEARCH

The purpose of this study was to describe the occurrence of significant mood disturbance and evaluate for differences in sleep quality among four mood groups (i.e., neither anxiety nor depression, only anxiety, only depression, anxiety and depression) prior to the initiation of radiation therapy (RT).

METHODS AND SAMPLE

Patients (n=179) with breast, prostate, lung, and brain cancer were evaluated prior to the initiation of RT using the Pittsburgh Sleep Quality Index (PSQI), the Center for Epidemiological Studies Depression Scale, and the Spielberger State Anxiety Inventory. Differences in sleep disturbance among the four mood groups were evaluated using analyses of variance.

KEY RESULTS

While 38% of the patients reported some type of mood disturbance, 57% of the patients reported sleep disturbance. Patients with clinically significant levels of anxiety and depression reported the highest levels of sleep disturbance.

CONCLUSIONS

Overall, oncology patients with mood disturbances reported more sleep disturbance than those without mood disturbance. Findings suggest that oncology patients need to be assessed for mood and sleep disturbances.

Sleep and cancer: recent developments

During the past decade, the critical role of sleep in health and disease has been underscored by research that further defines the relationship between sleep and myriad physiologic and psychological functions as well as quality of life. For many years, there was little exploration of the significance of sleep and sleep disorders in cancer patients; however, the past decade has seen a steady growth of inquiry in this area. These investigations have demonstrated the high frequency and significance of sleep disturbance as a symptom in cancer patients. They have also explored the complex interaction between sleep and other common cancer symptoms, most notably fatigue, depression, and pain, and have identified risk factors associated with the development of sleep problems in this population. Although treatment studies lag behind, reports of effective psychological and behavioral interventions for insomnia in cancer patients are increasing. Several studies are addressing pharmacotherapeutic intervention for hot flashes as a potential source of sleep disturbance. Other sleep disorders, most notably obstructive sleep apnea, also occur with some regularity in cancer patients.
