The Value of Screening for a History of Incarceration in the Palliative Care Setting.

The United States (US) has one of the highest rates of incarceration in the world. Due to the aging of the US population as a whole and limited opportunities for early release, the proportion of older people in prison continues to rise. Some correctional health systems have adopted geriatric and palliative care principles to better care for this aging population, many of whom die in prison. However, not everyone who grows old in prison will die behind bars. In this article, we explore existing literature that highlights the unique physical, cognitive, and psychosocial challenges that formerly incarcerated patients face. We proceed to argue that palliative care providers should screen for a history of incarceration to identify and address the needs of this patient population. We also offer strategies to create a safe, welcoming environment to discuss past traumas related to these patients' time in prison.

Identifying cancer patients who received palliative care using the SPICT-LIS in medical records: a rule-based algorithm and text-mining technique.

BACKGROUND: Due to limited numbers of palliative care specialists and/or resources, accessing palliative care remains limited in many low and middle-income countries. Data science methods, such as rule-based algorithms and text mining, have potential to improve palliative care by facilitating analysis of electronic healthcare records. This study aimed to develop and evaluate a rule-based algorithm for identifying cancer patients who may benefit from palliative care based on the Thai version of the Supportive and Palliative Care Indicators for a Low-Income Setting (SPICT-LIS) criteria. METHODS: The medical records of 14,363 cancer patients aged 18 years and older, diagnosed between 2016 and 2020 at Songklanagarind Hospital, were analyzed. Two rule-based algorithms, strict and relaxed, were designed to identify key SPICT-LIS indicators in the electronic medical records using tokenization and sentiment analysis. The inter-rater reliability between these two algorithms and palliative care physicians was assessed using percentage agreement and Cohen's kappa coefficient. Additionally, factors associated with patients might be given palliative care as they will benefit from it were examined. RESULTS: The strict rule-based algorithm demonstrated a high degree of accuracy, with 95% agreement and Cohen's kappa coefficient of 0.83. In contrast, the relaxed rule-based algorithm demonstrated a lower agreement (71% agreement and Cohen's kappa of 0.16). Advanced-stage cancer with symptoms such as pain, dyspnea, edema, delirium, xerostomia, and anorexia were identified as significant predictors of potentially benefiting from palliative care. CONCLUSION: The integration of rule-based algorithms with electronic medical records offers a promising method for enhancing the timely and accurate identification of patients with cancer might benefit from palliative care.

Cross-cultural adaptation and psychometric validation of point-of-care outcome assessment tools in Chinese palliative care clinical practice.

BACKGROUND: A standardized national approach to routinely assessing palliative care patients helps improve patient outcomes. However, a quality improvement program-based on person centered outcomes within palliative care is lacking in Mainland China. The well-established Australian Palliative Care Outcome Collaboration (PCOC) national model improves palliative care quality. This study aimed to culturally adapt and validate three measures that form part of the PCOC program for palliative care clinical practice in China: The PCOC Symptom Assessment Scale (PCOC SAS), Palliative Care Problem Severity Scale (PCPSS), Palliative Care Phase. METHODS: A study was conducted on cross-cultural adaptation and validation of PCOC SAS, PCPSS and Palliative Care Phase, involving translation methods, cognitive interviewing, and psychometric testing through paired assessments. RESULTS: Cross-cultural adaptation highlighted the need to strengthen the link between the patient's care plan and the outcome measures to improve outcomes, and the concept of distress in PCOC SAS. Analysis of 368 paired assessments (n = 135 inpatients, 22 clinicians) demonstrated that the PCOC SAS and PCPSS had good and acceptable coherence (Cronbach's a = 0.85, 0.75 respectively). Palliative Care Phase detected patients' urgent needs. PCOC SAS and PCPSS showed fair discriminant and concurrent validity. Inter-rater reliability was fair for Palliative Care Phase (k = 0.31) and PCPSS (k = 0.23-0.30), except for PCPSS-pain, which was moderate (k = 0.53). CONCLUSIONS: The Chinese version of PCOC SAS, PCPSS, and Palliative Care Phase can be used to assess outcomes as part of routine clinical practice in Mainland China. Comprehensive clinical education regarding the assessment tools is necessary to help improve the inter-rater reliability.

Challenges for palliative care in times of COVID-19: a scoping review.

Introduction: Many of the essential practices in palliative care (PC) had to be adapted to the COVID-19 pandemic. This global spread of the infectious respiratory disease, caused by SARS-CoV-2, created unprecedented obstacles. The aim of this research was to comprehensively assess the experiences and perceptions of healthcare professionals, individuals, and families in palliative and end-of-life situations during the COVID-19 pandemic. Methods: A scoping review was conducted using the databases CINAHL Complete, MEDLINE, Scopus, SciELO, Cochrane Central Register of Controlled Trials, Psychology and Behavioral Sciences, MEDIClatina, and Portugal's Open Access Scientific Repository. The review followed the JBI® methodological approach for scoping reviews. Results: Out of the initially identified 999 articles, 22 studies were included for analysis. The deprivation of relationships due to the safety protocols required to control the spread of COVID-19 was a universally perceived experience by healthcare professionals, individuals in PC, and their families. Social isolation, with significant psychological impact, including depersonalization and despair, was among the most frequently reported experiences by individuals in palliative situation. Despite healthcare professionals' efforts to mitigate the lack of relationships, the families of these individuals emphasized the irreplaceability of in-person bedside contact.

[Palliative care in paediatric oncology - a national parental perspective]. / Palliativ vård av barn med cancer.

The WHO definition of paediatric palliative care (PPC) emphasises the role of active multidimensional care, carried out with interdisciplinary competence, and providing support to the entire family. The aim of the current national study was to investigate whether parents perceived that their child received palliative care (PC) before the child died of cancer and the parent's view of the care during the child's last month of life. In 2016, parents (n=226) completed a study-specific survey, and a majority reported that their child had received PC with good professional competence. However, many parents reported that the child was greatly affected by pain in the last month of life. Geographical differences indicated that parents who live in sparsely populated areas to a lesser extent reported that their child received PC. Lastly, our conclusion is that access to equal PPC and improved symptom control is crucial for children and their families.

Pattern of Prescribing Analgesics and Their Response in Cancer Patients Attending Outpatient Department of Palliative Care Service in Two Teaching Hospitals of Bangladesh.

Palliative care is a valued aspect of clinical care which is an urgent humanitarian need for people worldwide with cancer and other chronic fatal diseases. Patients experience many different symptoms including severe pain in advanced cancer. Palliative care focuses on relief from symptoms, pain and stress by using different analgesics and adjuvant. The goal of palliative care is to improve the quality of life. So, this prospective observational study was carried out to assess pattern of drugs used and their response to pain in cancer patients attending out-patient department of palliative care service in two teaching hospitals of Bangladesh. One hundred forty (140) cancer patients were purposively selected who attended in out-patient department of palliative care unit in Bangabandhu Sheikh Mujib Medical University (BSMMU) and Dhaka Medical College Hospital (DMCH) from July 2018 to June 2019. Outcome variables were commonly presenting complaints, pain intensity, commonly prescribed drugs and analgesic prescription according to WHO three-step analgesic ladder, etc. The mean age ±SD of the respondents was 51.30±15.38 years, male-female ratio 1:1. Common sites of cancer were alimentary origin (20.0%), genitourinary system (17.86%), hepatobiliary system (11.43%), respiratory system (10.71%). The prescribed drugs were analgesics (96.4%), PPIs (74.3%), laxatives (62.1%), anti-emetics (38.6%), multivitamins (32.9%), H2 antagonists (17.1%), sedatives (17.1%), and corticosteroids (8.6%). Level 1 analgesics (Paracetamol or other NSAIDs) were prescribed to 42.65%, level 2 analgesics (Tramadol) were prescribed to 50.00% patients and level 3 analgesics (Morphine) were prescribed to 51.42% patients. The relation between and receiving three levels of analgesic prescriptions was statistically significant. The association between level of analgesic prescription was significant with site of cancer (p<0.001) and intensity of pain (p<0.001). This study showed that morphine was prescribed to more than half of the patients. Other level of analgesics were also used either single or in combination. Younger and male patients were treated more with level III analgesics. Prescribing analgesics were dependent on sites of cancer and intensity of pain.

[Quality of live of palliative outpatient care in Westphalia-Lippe focusing on contentedness of patients and their relatives - a multicenter cohort study]. / Qualität der ambulanten Palliativversorgung im Modell Westfalen-Lippe hinsichtlich der Zufriedenheit von Patienten und ihren Zugehörigen : Eine multizentrische Kohortenstudie.

BACKGROUND: In Westphalia-Lippe - unlike the rest of Germany - outpatient palliative care, as general and specialized palliative care (AAPV and SAPV), exists as part of an innovative care model. Ten years after its introduction, an evaluation is to be carried out, focusing on the treatment satisfaction of patients and their relatives as well as the extent to which the model has proved successful in urban versus rural care contexts. METHODS: In a multicenter cohort study, in 2019/20, from a total of 36 palliative care regions, 12 - 4 metropolitan, mixed and rural each - were randomly selected, with 20 palliative patients each. Using established instruments (MIDOS, HOPE), the patients were questioned about stressful symptoms and quality of life. Additionally, their relatives were asked about their satisfaction with the care provided. RESULTS: 227 patients were included. The care period was 82.3 days on average (median 47.5). Distressing symptoms were consistently well controlled with a slight tendency for symptoms to increase at the end of life (NRS < 4). There were no significant differences between urban and rural regions. The outpatient palliative care provided by doctors and nurses in Westphalia-Lippe was largely viewed positively by the relatives. CONCLUSIONS: In Westphalia-Lippe, patients in need of palliative care can be offered early and low- threshold structured outpatient palliative care, which is mainly provided by GPs and outpatient specialists. The role of the GP in primary medical care is being strengthened. In this interprofessional and interdisciplinary model, patient care is demand-oriented, that is, the intensity of care can switch between general (AAPV) and specialized care (SAPV) according to the disease progress. This model has proven itself in practice and provides good services benefits for palliative patients and their relatives.

Medicaid expansion and palliative care for advanced-stage liver cancer.

BACKGROUND: Medicaid expansion (ME) has contributed to transforming the United States healthcare system. However, its effect on palliative care of primary liver cancers remains unknown. This study aimed to evaluate the association between ME and the receipt of palliative treatment in advanced-stage liver cancer. METHODS: Patients diagnosed with stage IV hepatocellular carcinoma or intrahepatic cholangiocarcinoma were identified from the National Cancer Database and divided into pre-expansion (2010-2013) and postexpansion (2015-2019) cohorts. Logistic regression identified predictors of palliative treatment. Difference-in-difference (DID) analysis assessed changes in palliative care use between patients living in ME states and patients living in non-ME states. RESULTS: Among 12,516 patients, 4582 (36.6%) were diagnosed before expansion, and 7934 (63.6%) were diagnosed after expansion. Overall, rates of palliative treatment increased after ME (18.1% [pre-expansion] vs 22.3% [postexpansion]; P < .001) and are more pronounced among ME states. Before expansion, only cancer type and education attainment were associated with the receipt of palliative treatment. Conversely, after expansion, race, insurance, location, cancer type, and ME status (odds ratio [OR], 1.23; 95% CI, 1.06-1.44; P = .018) were all associated with palliative care. Interestingly, the odds were higher if treatment involved receipt of pain management (OR, 2.05; 95% CI, 1.23-2.43; P = .006). Adjusted DID analysis confirmed increased rates of palliative treatment among patients living in ME states relative to non-ME states (DID, 4.4%; 95% CI, 1.2-7.7; P = .008); however, racial disparities persist (White, 5.6; 95% CI, 1.4-9.8; P = .009; minority, 2.6; 95% CI, -2.5 to 7.6; P = .333). CONCLUSION: The implementation of ME contributed to increased rates of palliative treatment for patients residing in ME states after expansion. However, racial disparities persist even after ME, resulting in inequitable access to palliative care.

Factors associated with non-completion of palliative radiotherapy for spinal metastasis in patients with terminal cancer: a retrospective study.

BACKGROUND: Predictors of non-completion of radiotherapy (RT) should be identified to determine the optimal RT dose. Therefore, this study aimed to explore factors associated with non-completion of palliative RT in patients with terminal cancer. METHODS: In this retrospective study, patients with terminal cancer who received RT (not including single-fraction RT) for relief of pain caused by spinal metastasis were categorized into complete and incomplete groups. Baseline characteristics, hematologic test data [e.g., total lymphocyte count (TLC)], performance status, palliative performance scale (PPS) score, psoas muscle index (PMI), Charlson comorbidity index, and age-adjusted Charlson comorbidity index of the patients were compared between the two groups. RESULTS: The complete group comprised 58 patients (median age: 68 years; female/male: 17/41; number of irradiation fractions: ≥2 to <10, 20 patients; 10, 34 patients; and >10, 4 patients), and the incomplete group comprised 9 patients (median age: 68 years; female/male: 3/6; number of irradiation fractions: ≥2 to <10, 2 patients; 10, 7 patients; and >10, 0 patient). The proportion of patient death within 1 week or 1 month was higher in the incomplete group than in the complete group. Compared with that in the incomplete group, TLC measured 1 week before RT (pre-TLC) and PMI recorded before RT were significantly higher in the complete group (P=0.013 and P=0.012, respectively). In multivariable analyses, pre-TLC was significantly associated with the incomplete group (P=0.048). Compared with the complete group, the incomplete group included several patients whose PPS scores rapidly decreased. CONCLUSIONS: Pre-TLC can predict non-completion of palliative RT in patients with terminal cancer.

Integrating palliative care in patients with advanced multiple sclerosis: a scoping review.

BACKGROUND: Multiple sclerosis (MS) often presents a long and uncertain evolution. Treatment decisions in advanced MS are supported by robust evidence, but recent guidelines have suggested a shift to a palliative approach as the disease progresses. This study aims to describe what is known about the integration of palliative care (PC) in patients with severe MS (cost-effectiveness, moment of reference, and perspective of stakeholders). METHODS: A scoping review was developed, and the Scopus, Medline (PubMed), ISI Web of Knowledge, and SAGE databases were consulted, using the key terms: "multiple sclerosis" AND "palliative care". Studies on the perspectives of patients, caregivers, and health professionals regarding the integration of PC in MS were included. No restrictions were applied regarding the subtype of MS, gender, ethnicity, frequency of use of health services, and language. RESULTS: Of 158 articles identified, 19 were included in the review. Key factors were identified, such as the effectiveness of PC intervention in severe MS, the financial impact of providing PC compared to conventional care, the reduction of symptoms and caregiver burden, and the perception of unmet needs by users, health professionals, and caregivers during the PC approach. CONCLUSIONS: Patients with MS should have access to specialized PC when they reach the severe phase of the disease. Providing a multidisciplinary team to provide targeted consultations based on the patient's needs may be most appropriate. These issues have important implications for the future planning and provision of PC services.

Institutions and institutionalisation: They're part of everyday life.

BACKGROUND: Institutions are established patterns of recurrent social relationships playing a fundamental part in all our lives. The family is the best-known institution, but other 'total' institutions serve as organisations directly affecting the lives of many individuals in the healthcare sector. OBJECTIVE: This paper examines the sociological theory of institutionalisation as applied to individuals admitted to aged-care facilities, where the complete life-rounds of inmates occur within clearly defined limits. The study provides a framework to enable general practitioners, nurses and healthcare professionals to better appreciate the processes involved as individuals adapt to their new environment. DISCUSSION: Sociology provides valuable insights for healthcare providers in understanding how individuals adapt to their loss of independent living and find themselves subjected to intimate regulation in the total institution. The biopsychosocial model of healthcare delivery is better understood when we as health professionals have greater insights to appreciate the competing processes at work.

Integrating Hospice and Palliative Medicine Education Within the American Board of Emergency Medicine Model.

Background: Hospice and palliative medicine (HPM) is a board-certified subspecialty within emergency medicine (EM), but prior studies have shown that EM residents do not receive sufficient training in HPM. Experts in HPM-EM created a consensus list of competencies for HPM training in EM residency. We evaluated how the HPM competencies integrate within the American Board of Emergency Medicine Milestones, which include the Model of the Clinical Practice of Emergency Medicine (EM Model) and the knowledge, skills, and abilities (KSA) list. Methods: Three emergency physicians independently mapped the HPM-EM competencies onto the 2019 EM Model items and the 2021 KSAs. Discrepancies were resolved by a fourth independent reviewer, and the final mapping was reviewed by all team members. Results: The EM Model included 78% (18/23) of the HPM competencies as a direct match, and we identified recommended areas for incorporating the other five. The KSAs included 43% (10/23). Most HPM competencies included in the KSAs mapped onto at least one level B (minimal necessary for competency) KSA. Three HPM competencies were not clearly included in the EM Model or in the KSAs (treating end-of-life symptoms, caring for the imminently dying, and caring for patients under hospice care). Conclusion: The majority of HPM-EM competencies are included in the current EM Model and KSAs and correspond to knowledge needed to be competent in EM. Programs relying on the EM Milestones to plan their curriculums may miss training in symptom management and care for patients at the end of life or who are on hospice.

Implementing evidence ecosystems in the public health service: Development of a framework for designing tailored training programs.

The COVID-19 pandemic has highlighted the importance of local evidence ecosystems in which academia and practice in the Public Health Service (PHS) are interconnected. However, appropriate organizational structures and well-trained staff are lacking and evidence use in local public health decision-making has to be integrated into training programs in Germany. To address this issue, we developed a framework incorporating a toolbox to conceptualize training programs designed to qualify public health professionals for working at the interface between academia and practice. We conducted a scoping review of training programs, key-informant interviews with public health experts, and a multi-professional stakeholder workshop and triangulated their output. The resulting toolbox consists of four core elements, encompassing 15 parameters: (1) content-related aspects, (2) context-related aspects, (3) aspects relevant for determining the training format, and (4) aspects relevant for consolidation and further development. Guiding questions with examples supports the application of the toolbox. Additionally, we introduced a how-to-use guidance to streamline the creation of new training programs, fostering knowledge transfer at the academia-practice interface, equipping public health researchers and practitioners with relevant skills for needs-based PHS research. By promoting collaborative training development across institutions, our approach encourages cross-institutional cooperation, enhances evidence utilization, and enables efficient resource allocation. This collaborative effort in developing training programs within local evidence ecosystems not only strengthens the scientific and practical impact but also lays a foundation for implementing complex public health measures effectively at the local level.

Facilitators and barriers of implementing end-of-life care volunteering in a hospital in five European countries: the iLIVE study.

BACKGROUND: End-of-life (EoL) care volunteers in hospitals are a novel approach to support patients and their close ones. The iLIVE Volunteer Study supported hospital volunteer coordinators from five European countries to design and implement an EoL care volunteer service on general wards in their hospitals. This study aimed to identify and explore barriers and facilitators to the implementation of EoL care volunteer services in the five hospitals. METHODS: Volunteer coordinators (VCs) from the Netherlands (NL), Norway (NO), Slovenia (SI), Spain (ES) and United Kingdom (UK) participated in a focus group interview and subsequent in-depth one-to-one interviews. A theory-inspired framework based on the five domains of the Consolidated Framework for Implementation Research (CFIR) was used for data collection and analysis. Results from the focus group were depicted in radar charts per hospital. RESULTS: Barriers across all hospitals were the COVID-19 pandemic delaying the implementation process, and the lack of recognition of the added value of EoL care volunteers by hospital staff. Site-specific barriers were struggles with promoting the service in a highly structured setting with many stakeholders (NL), negative views among nurses on hospital volunteering (NL, NO), a lack of support from healthcare professionals and the management (SI, ES), and uncertainty about their role in implementation among VCs (ES). Site-specific facilitators were training of volunteers (NO, SI, NL), involving volunteers in promoting the service (NO), and education and awareness for healthcare professionals about the role and boundaries of volunteers (UK). CONCLUSION: Establishing a comprehensive EoL care volunteer service for patients in non-specialist palliative care wards involves multiple considerations including training, creating awareness and ensuring management support. Implementation requires involvement of stakeholders in a way that enables medical EoL care and volunteering to co-exist. Further research is needed to explore how trust and equal partnerships between volunteers and professional staff can be built and sustained. TRIAL REGISTRATION: NCT04678310. Registered 21/12/2020.

What influences specialist palliative care nurses working in a community setting to engage with research?

AIMS: The aim of this research was to understand what influences specialist palliative care nurses working in a community setting to engage with research. METHODS: Qualitative research using interviews with community based clinical nurse specialists (CNS). FINDINGS: A total of five themes were identified: research negativity and enthusiasm, clinical focus, audits, organisational support and keeping up to date. CONCLUSION: Except for audit activity, CNS do not view the research pillar as an integral part of their clinical role. Previous research education may not give the CNS the breadth of research skills that they require. The advance professional apprenticeship may resolve these education issues. Managers and organisations need to prioritise EBP skills; supporting nurses with both education and EBP mentors to develop these skills. Nurses require ongoing time to engage with research activity and use these skills to improve both their own clinical practice and those who use them as a research resource.

Environmental Comfort in Promoting Sleep in Critically Ill Patients: A Scoping Review.

INTRODUCTION: It is important to understand the concept of comfort as a whole to build an assistance intervention plan that meets the person's needs. Therefore, it is necessary to monitor and assess the person's sleep by considering the surrounding environment, to provide a comfortable environment that is quiet and provides privacy, especially in contexts of difficult management of environmental factors in the approach to the person in critical condition. OBJECTIVES: The aims of this study were to map the nursing interventions that promote sleep-promoting environmental comfort in critically ill people and identify the instruments to assess sleep in critically ill people. METHODS: This is a scoping review based on the methodological strategy of the Joanna Briggs Institute for Scoping Reviews. The search was conducted on February 17 and 18, 2022, in the databases CINAHL, Cochrane Library Plus, PubMed, JBI Evidence Synthesis, SciELO, DANS Easy Archive, RCAAP, and DART-Europe using the Boolean phrase search strategy: "Hospital Emergency Service" OR "Critical Care" AND "Sleep" NOT "Children" AND Nurs*. We included all studies, conducted in any contextual setting, in Portuguese, English, or Spanish, on adult patients with acute and/or critical illness in intensive care and/or emergency units, which addressed nursing interventions that contribute to environmental comfort and promote sleep. Studies on pregnant or puerperal women, persons with psychiatric disorders, and those at the end of life or in palliative care were excluded. RESULTS: Twenty-one articles were included in this scoping review. Three categories of nursing interventions emerged: person centered (14 interventions), environment centered (37 interventions), and nurse role centered (45 interventions). Three categories of instruments for sleep assessment emerged, in particular: quality of sleep (12 instruments), environmental effects on a night's sleep (2 instruments), and influence on sleep practices in the intensive care unit (1 instrument). DISCUSSION: The use of instruments to monitor comfort and sleep allows for an accurate assessment of the impact of nurses' intervention focusing on sleep-promoting interventions aimed at comfort, for an improvement of sleep in critically ill patients. CONCLUSION: The interpretation of the content makes it clear that how critically ill patients in different contexts experience the environmental context positively or negatively conditions their comfort. In this sense, it is essential to reflect on these measures as a team so that everyone can apply them.

Family Members' Engagement in Symptom Communication, Assessment, and Management in the Intensive Care Unit: A Qualitative Study.

BACKGROUND: Opportunities for communication and participation in decision making are limited for critically ill patients, but family members serving as surrogates enable empowerment of these patients. OBJECTIVE: The aim of this study was to explore family members' engagement in symptom communication in the intensive care unit. METHODS: A qualitative descriptive design using fieldwork methodology with triangulation of participant observation and individual interviews was conducted. Nine mechanically ventilated patients were observed in interaction with family members and clinicians in the intensive care unit. Six of the observed patients, 6 family members, and 9 clinicians were interviewed after participant observation. Field notes and transcripts were analyzed using Braun and Clarke's method of thematic analysis. RESULTS: Family members engaged actively in symptom communication, assessment, and management, and there were barriers and facilitators to family engagement. Three main themes and 9 subthemes describing family engagement emerged: (1) intermediary role (recognize and report symptoms, provide patient information, and assist in communication), (2) independent role (provide familiarity, manage symptoms, and promote patient communication), and (3) conditions for family engagement (intensive care unit environment, relationship with the patient, and patient preferences). DISCUSSION: Family members have unique knowledge of the patient that differs from and complement the competence of the staff, and might contribute to improved symptom communication. Future research should examine how family members can contribute to symptom communication, assessment, and management.

[Palliative Care in patients with gastrointestinal cancer]. / Palliativmedizin in der gastrointestinalen Onkologie.

Comprehensive Cancer Care stands for a concept of broad care providing substantial benefits to cancer patients. Beside prevention of cancer as first pillar and curative therapy as second pillar, comprehensive care also encompasses palliative care representing a third pillar providing service for incurable cancer patients burdened with physical symptoms and psychological, social and spiritual needs. This article describes the integration of palliative medicine into comprehensive cancer care for patients with gastrointestinal cancer.
