Prevalence, intensity, and prognostic significance of common symptoms in terminally ill cancer patients

Evaluating the Utility of the Surprise Question Among General Physicians for Appropriate Palliative Care Indication in Brazil

Objectives

This study aimed to assess the agreement between established tools, such as the Palliative Performance Scale (PPS) and Brazilian version of the Supportive and Palliative Care Indicators Tool (SPICT-BR), and the subjective assessment of palliative care (PC) need using the Surprise Question (SQ) administered by resident physicians. This assessment was conducted among hospitalized patients, with and without cancer, to determine the efficacy of these tools in indicating the need for PC.

Methods

A six-month cross-sectional study in 2019 of medical records of patients hospitalized in a single center in IAMSPE-Brazil. The SPICT-BR and PPS were applied to the medical record data, and the SQ was posed to each resident physician. Comparisons for categorical data were made using the chi-square test, with p < 0.05 considered statistically significant.

Results

Of 203 patients evaluated, 57.6% were male and 81.2% were older adults (≥60 years). The mean age was 67.40 ± 9.72 years. Chronic disease was nonneoplastic in 78.32% of patients, and 56.65% had not been hospitalized in the preceding year. The PPS score was <70% in 69.4% of patients, and 51.2% met at least one SPICT-BR criterion. Among patients with cancer, 40.9% had over two positive SPICT-BR criteria; 97.5% of these patients received NO responses to SQ by residents (p < 0.0001). Similarly, 90.6% of patients with one SPICT-BR criterion received NO responses to SQ, with no significant difference between groups.

Conclusion

The SQ proved to be a valuable tool for PC indication, particularly when administered by untrained professionals. Consistent with SPICT-BR findings, our study highlights the SQ's role in facilitating early identification of patients in need of PC.

Development and external validation of a machine learning-based prediction model for the cancer-related fatigue diagnostic screening in adult cancer patients: a cross-sectional study in China

PURPOSE

Cancer-related fatigue (CRF) is the most common symptom in cancer patients and may interfere with patients' daily activities and decrease survival rate. However, the etiology of CRF has not been identified. Diagnosing CRF is challenging. Thus, our study aimed to develop a CRF prediction model in cancer patients, using data that healthcare professionals routinely obtained from electronic health records (EHRs) based on the 3P model and externally validate this model in an independent dataset collected from another hospital.

METHODS

Between April 2022 and September 2022, a cross-sectional study was conducted on adult cancer patients at two first-class tertiary hospitals in China. Data that healthcare professionals routinely obtained from electronic health records (EHRs) based on the 3P model were collected. The outcome measure was according to ICD-10 diagnostic criteria for CRF. Data from one hospital (n = 305) were used for model development and internal validation. An independent data set from another hospital (n = 260) was utilized for external validation. logistic regression, random forest (RF), Naive Bayes (NB), and extreme gradient boosting (XGBoost) were constructed and compared. The model performance was evaluated in terms of both discrimination and calibration.

RESULTS

The prevalence of CRF in the two centers was 57.9% and 56.1%, respectively. The Random Forest model achieved the highest AUC of 0.86 among the four types of classifiers in the internal validation. The AUC of RF and NB were above 0.7 in the external validation, suggesting that the models also have an acceptable generalization ability.

CONCLUSIONS

The incidence of CRF remains high and deserves more attention. The fatigue prediction model based on the 3P theory can accurately predict the risk of CRF. Nonlinear algorithms such as Random Forest and Naive Bayes are more suitable for diagnosing and evaluating symptoms.

Loss of Appetite in Adult Patients: Effectiveness and Safety of an Appetite Stimulating Medication in an Open-Label, Investigator-Initiated Study in India

Loss of appetite (LOA) may have a negative impact on a patient's well-being owing to loss of nutrition and associated conditions. The current study assessed the effects of an appetite-stimulating medication containing multivitamins, lysine, and zinc in Indian patients with a history of LOA. Using an investigator-initiated, single-center, open-label, single-arm design, we evaluated the effectiveness and safety of the appetite-stimulating medication (15 mL) in 50 male or female patients (18–55 years old) attending the outpatient department, with a confirmed diagnosis of LOA after two weeks of therapy and assessed the change in Council on Nutrition Appetite Questionnaire (CNAQ) score and safety of the medication after two weeks of treatment. CNAQ scores were presented as mean (standard deviation (SD)). The mean age of patients was 42.1 years, with the majority (66%) being males. At weeks 1 and 2, a statistically significant improvement was observed in the mean CNAQ scores of 25.48 (5.10) and 25.48 (4.29), respectively, vs. baseline (22.08 (2.76); P ≤ 0.0001 both). Majority of the patients had CNAQ appetite scores of 17–28 at baseline (94%), week 1 (66%), and week 2 (78%) of treatment. For patients with acute and chronic illness, a statistically significant improvement was observed in the mean CNAQ score at week 1 (26.75 (3.69), P = 0.0256; 25.24 (5.33), P = 0.0004) and at week 2 (26.63 (3.46), P = 0.0027; 25.26 (4.43), P ≤ 0.0001) from baseline (21.88 (3.31) and 22.12 (2.69), respectively). No serious adverse events were reported during the study. The study findings suggest that appetite-stimulating medication containing multivitamins, lysine, and zinc could be a suitable treatment option for the management of LOA with no significant safety concerns.

Clinically significant symptoms prevalence in breast and colon cancers and leukemia patients: a comparison analysis of patient-reported outcomes

PURPOSE

To assess the prevalence and severity of clinically significant symptoms (CSSs) for breast cancer, colon cancer, and leukemia patients undergoing chemotherapy.

METHODS

A retrospective review of the Edmonton Symptom Assessment System scores reported by patients from the database of our previous large-scale study, which was collected between May 2018 and January 2019. We described the prevalence of CSSs in proportion and severity in mean ± SD.

RESULTS

Of 546 cancer patients, 209 were breast cancer, 159 were colon cancer, and 178 were leukemia. The majority of participants were females 345 (63.2%), and the mean age of the entire study sample was 49.4 ± 13.93. Diminished feeling of well-being was the most prevalent CSS across the three cancers, with a statistically significant difference (p < 0.001). Fatigue (6.59 ± 2.07), pain (6.55 ± 2.01), and loss of appetite were the most distressing CSSs (6.49 ± 1.99) across the whole sample. Loss of appetite (6.34 ± 2.05) was the most distressing CSS in breast cancer, fatigue (6.97 ± 2.07) in leukemia, and pain (7.00 ± 2.11) in colon cancer. Statistically significant differences were found in the severity between the three cancer in pain (p < 0.001), fatigue (p = 0.010), nausea (p = 0.001), and diminished feeling of well-being (p = 0.033). Cancer type, sleeping hours, dependence on caregiver, female gender, level of education, and employment were significantly associated with higher odds of CSS severity.

CONCLUSION

Breast and colon cancer and leukemia patients undergoing chemotherapy experience multiple distressing CSSs. Our study validates CSSs as a discrete set of distressing symptoms that may serve and guide quality of care assessment and cancer clinical research, particularly among patients undergoing chemotherapy.

Patient-Reported Outcomes as Independent Prognostic Factors for Survival in Oncology: Systematic Review and Meta-Analysis

OBJECTIVES

Assessment of patient-reported outcomes (PROs) in oncology is of critical importance because it provides unique information that may also predict clinical outcomes.

METHODS

We conducted a systematic review of prognostic factor studies to examine the prognostic value of PROs for survival in cancer. A systematic literature search was performed in PubMed for studies published between 2013 and 2018. We considered any study, regardless of the research design, that included at least 1 PRO domain in the final multivariable prognostic model. The protocol (EPIPHANY) was published and registered in the International Prospective Register of Systematic Reviews (CRD42018099160).

RESULTS

Eligibility criteria selected 138 studies including 158 127 patients, of which 43 studies were randomized, controlled trials. Overall, 120 (87%) studies reported at least 1 PRO to be statistically significantly prognostic for overall survival. Lung (n = 41, 29.7%) and genitourinary (n = 27, 19.6%) cancers were most commonly investigated. The prognostic value of PROs was investigated in secondary data analyses in 101 (73.2%) studies. The EORTC QLQ-C30 questionnaire was the most frequently used measure, and its physical functioning scale (range 0-100) the most frequent independent prognostic PRO, with a pooled hazard ratio estimate of 0.88 per 10-point increase (95% CI 0.84-0.92).

CONCLUSIONS

There is convincing evidence that PROs provide independent prognostic information for overall survival across cancer populations and disease stages. Further research is needed to translate current evidence-based data into prognostic tools to aid in clinical decision making.

Clinically Significant Depressive Symptoms Are Prevalent in People With Extremely Short Prognoses-A Systematic Review

CONTEXT

Currently, systematic evidence of the prevalence of clinically significant depressive symptoms in people with extremely short prognoses is not available to inform its global burden, assessment, and management.

OBJECTIVES

To determine the prevalence of clinically significant depressive symptoms in people with advanced life-limiting illnesses and extremely short prognoses (range of days to weeks).

METHODS

A systematic review and meta-analysis (random-effects model) were performed (PROSPERO: CRD42019125119). MEDLINE, Embase, PsycINFO, CINAHL, and CareSearch were searched for studies (1994-2019). Data were screened for the prevalence of clinically significant depressive symptoms (assessed using validated depression-specific screening tools or diagnostic criteria) of adults with advanced life-limiting illnesses and extremely short prognoses (defined by survival or functional status). Quality assessment was performed using the Joanna Briggs Institute Systematic Reviews Checklist for Prevalence Studies for individual studies and Grading of Recommendations Assessment, Development and Evaluation (GRADE) across studies.

RESULTS

Thirteen studies were included. The overall pooled prevalence of clinically significant depressive symptoms in adults with extremely short prognoses (n = 10 studies; extremely short prognoses: N = 905) using depression-specific screening tools was 50% (95% CI: 29%-70%; I² = 97.6%). Prevalence of major and minor depression was 10% (95% CI: 4%-16%) and 5% (95% CI: 2%-8%), respectively. Major limitations included high heterogeneity, selection bias, and small sample sizes in individual studies.

CONCLUSIONS

Clinically, significant depressive symptoms were prevalent in people with advanced life-limiting illnesses and extremely short prognoses. Clinicians need to be proactive in the recognition and assessment of these symptoms to allow for timely intervention.

RESUMO Objetivo: avaliar a qualidade de vida relacionada à saúde de pacientes com câncer em cuidados paliativos e sua associação com aspectos sociodemográficos e clínicos. Método: estudo analítico, transversal, do qual participaram 127 pacientes. Foram utilizados instrumentos de caracterização sociodemográfica e de avaliação de qualidade de vida - European Organization for Research and Treatment for Cancer. Para análise dos dados, aplicaram-se os testes Kolmogorov-Smirnov, Mann-Whitney e Kruskal-Wallis. Resultados: na avaliação de qualidade de vida, o Estado de Saúde Global e Função Desempenho de Papel tiveram pior avaliação; na Escala de Sintomas, dor, fadiga, insônia e perda do apetite tiveram destaque. Na associação dos domínios do instrumento de coleta de dados com as variáveis sociodemográficas houve associação significativa da idade e escolaridade com função cognitiva, e de renda mensal com estado geral de saúde; com as variáveis clínicas houve associação significativa de metástase com função física; radioterapia com função social, e tempo de hospitalização com Escala Funcional. A Escala de Sintomas apresentou associação significativa de fadiga com metástase, quimioterapia e tempo de hospitalização; dor com quimioterapia e tempo de hospitalização; insônia com procedimento cirúrgico e perda de apetite com quimioterapia. Conclusão: o prejuízo na capacidade funcional, decorrente do câncer, afeta a capacidade do paciente de desempenhar atividades da vida diária, as relações sociais e a situação financeira. Aspectos sociodemográficos e clínicos devem ser considerados na avaliação da qualidade de vida desses pacientes, de forma a possibilitar atenção humanizada e integralizada aos princípios do Sistema Único de Saúde vigentes no Brasil.

Current Research Status of Palliative Care in Mainland China

Objectives:

This study aimed to obtain an overview of the current research status of palliative care in Mainland China and identify research directions for future studies by characterizing palliative care studies conducted among patients with any life-limiting illness in Mainland China and published in a peer-reviewed journal before November 2016.

Methods:

A review guide with 7 categories was initially developed based on existing international palliative care definitions and guidelines through content analysis. Ten databases were used to identify relevant studies from the inception of online cataloging to November 2016. Studies conducted in Mainland China and their research topic that fell within one of the categories of the review guide were included for further analysis. Descriptive analysis was adopted to summarize the relevant findings.

Results:

54 studies found to be relevant were included for the analysis. Three studies on “palliative care education and training” (category 1) asserted that education and training programs were scant in Mainland China and that only 1 program had been devised within the health-care context of Shanghai. Five studies on “palliative care screening and timely identification” (category 2) highlighted the absence of early screening criteria or checklists and referral procedures for palliative care. Thirty-one studies on “palliative care needs assessment (n = 12/31) and implementation (n = 19/31)” (category 3) were identified, and various methodological flaws were observed in most of these included studies. Twelve studies on “advanced decision-making” (category 4) were identified, all of which focused on investigating the attitudes of patients with cancer, their families, and/or health-care professionals toward advanced decision-making only. The percentage of patients, family members, and health-care professionals who held positive attitudes toward advanced decision-making were varied and suboptimal, particularly for family members (51.4%-58.0%). Five studies on “caring for patients at the end of life” (category 5) were identified, and the experience of health-care professionals in caring for those patients was explored. No studies relating to “death and bereavement care” (Category 6) and “psychological support for palliative care providers” (Category 7) were identified.

Conclusion:

The current research status of palliative care in Mainland China remains at an early stage with minimal palliative care services used. Although several knowledge gaps were identified, the first step, which should be addressed, is assessing the palliative care needs. An appropriate and ongoing needs assessment could provide important information for constructing comprehensive education and training programs of palliative care, identifying prognostic factors of timely palliative care referral, and developing evidence-based and tailored palliative care services.

Cancer pain management needs and perspectives of patients from Chinese backgrounds: a systematic review of the Chinese and English literature

Objective

More than half of all cancer patients experience unrelieved pain. Culture can significantly affect patients’ cancer pain-related beliefs and behaviors. Little is known about cultural impact on Chinese cancer patients’ pain management. The objective of this review was to describe pain management experiences of cancer patients from Chinese backgrounds and to identify barriers affecting their pain management.

Method

A systematic review was conducted adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Studies were included if they reported pain management experiences of adult cancer patients from Chinese backgrounds. Five databases were searched for peer-reviewed articles published in English or Chinese journals between1990 and 2015. The quality of included studies was assessed using Joanna Briggs Institution's appraisal tools.

Results

Of 3,904 identified records, 23 articles met criteria and provided primary data from 6,110 patients. Suboptimal analgesic use, delays in receiving treatment, reluctance to report pain, and/or poor adherence to prescribed analgesics contributed to the patients’ inadequate pain control. Patient-related barriers included fatalism, desire to be good, low pain control belief, pain endurance beliefs, and negative effect beliefs. Patients and family shared barriers about fear of addiction and concerns on analgesic side effects and disease progression. Health professional–related barriers were poor communication, ineffective management of pain, and analgesic side effects. Healthcare system–related barriers included limited access to analgesics and/or after hour pain services and lack of health insurance.

Significance of results

Chinese cancer patients’ misconceptions regarding pain and analgesics may present as the main barriers to optimal pain relief. Findings of this review may inform health interventions to improve cancer pain management outcomes for patients from Chinese backgrounds. Future studies on patients’ nonpharmacology intervention-related experiences are required to inform multidisciplinary and biopsychosocial approaches for culturally appropriate pain management.

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.

Prevalence and associated factors for decreased appetite among patients with stable heart failure

AIMS AND OBJECTIVES

To explore the prevalence of decreased appetite and factors associated with appetite among patients with stable heart failure.

BACKGROUND

Decreased appetite is an important factor for the development of undernutrition among patients with heart failure, but there are knowledge gaps about prevalence and the factors related to appetite in this patient group.

DESIGN

Observational, cross-sectional study.

METHODS

A total of 186 patients with mild to severe heart failure were consecutively recruited from three heart failure outpatient clinics. Data were obtained from medical records (heart failure diagnosis, comorbidity and medical treatment) and self-rated questionnaires (demographics, appetite, self-perceived health, symptoms of depression and sleep). Blood samples were taken to determine myocardial stress and nutrition status. Heart failure symptoms and cognitive function were assessed by clinical examinations. The Council on Nutrition Appetite Questionnaire was used to assess self-reported appetite. Bivariate correlations and multivariate linear regression analyses were conducted to explore factors associated with appetite.

RESULTS

Seventy-one patients (38%) experienced a loss of appetite with a significant risk of developing weight loss. The final multiple regression model showed that age, symptoms of depression, insomnia, cognitive function and pharmacological treatment were associated with appetite, explaining 27% of the total variance.

CONCLUSION

In this cross-sectional study, a large share of patients with heart failure was affected by decreased appetite, associated with demographic, psychosocial and medical factors.

RELEVANCE TO CLINICAL PRACTICE

Loss of appetite is a prevalent problem among patients with heart failure that may lead to undernutrition. Health care professionals should routinely assess appetite and discuss patients' experiences of appetite, nutrition intake and body weight and give appropriate nutritional advice with respect to individual needs.

Factors Associated with Short-Term Mortality After Surgical Oncologic Emergencies

BACKGROUND

The clinical outcome of patients with oncologic emergencies is often poor and mortality is high. It is important to determine which patients may benefit from invasive treatment, and for whom conservative treatment and/or palliative care would be appropriate. In this study, prognostic factors for clinical outcome are identified in order to facilitate the decision-making process for patients with surgical oncologic emergencies.

METHODS

This was a prospective registration study for patients over 18 years of age, who were consulted for surgical oncologic emergencies between November 2013 and April 2014. Multiple variables were registered upon emergency consultation, and the follow-up period was 90 days. Multivariate logistic regression analysis was performed to identify factors associated with 30- and 90-day mortality.

RESULTS

During the study period, 207 patients experienced surgical oncologic emergencies-101 (48.8 %) men and 106 (51.2 %) women, with a median age of 64 years (range 19-92). The 30-day mortality was 12.6 % and 90-day mortality was 21.7 %. Factors significantly associated with 30-day mortality were palliative intent of cancer treatment prior to emergency consultation (p = 0.006), Eastern Cooperative Oncology Group performance score (ECOG-PS) >0 (p for trend: p = 0.03), and raised lactate dehydrogenase (LDH) (p < 0.001). Additional factors associated with 90-day mortality were low handgrip strength (HGS) (p = 0.01) and low albumin (p = 0.002).

CONCLUSIONS

Defining the intent of prior cancer treatment and the ECOG-PS are of prognostic value when deciding on treatment for patients with surgical oncologic emergencies. Additional measurements of HGS, LDH, and albumin levels can serve as objective parameters to support the clinical assessment of individual prognosis.

Restorative care for palliative patients: a retrospective clinical audit of outcomes for patients admitted to an inpatient palliative care unit

BACKGROUND

Restorative care in palliative care is a subset of rehabilitation that aims to improve quality of life through restoration or maintenance of physical functions. Outcomes for restorative care programmes delivered by palliative care units have not adequately been assessed.

OBJECTIVES

The objectives are to examine the outcomes of a restorative care programme in an inpatient palliative care unit, including discharge destination, performance status changes and length of stay.

METHODS

Retrospective clinical audit of consecutive patients admitted to Calvary Health Care Bethlehem in Melbourne, Australia, principally for restorative care from July 2010 to December 2011.

RESULTS

79 admissions met inclusion criteria. Mean age was 76.5 years (SD=11.14) and 43 (54%) were men. 75 (95%) patients had a malignant diagnosis; of these, the majority had lung cancer (24%). 16 patients (20%) were discharged home, 51 (65%) died and 12 (15%) were transferred. Of the patients discharged home, only 6 (38% of those discharged home) improved their performance status. Those discharged home had a significantly shorter length of stay (17 days compared to 39 days; p<0.05). Patients discharged home also had significantly better Australia-modified Karnofsky Performance Status (AKPS) and Resource Utilisation Groups-Activities of Daily Living (RUG-ADL) scores on admission than others (both p<0.05).

CONCLUSIONS

The majority of patients referred for restorative care died during admission, with only a minority discharged home. Patients discharged most commonly experienced maintenance and not improvement in performance status. A successful discharge home following restorative care was associated with a shorter length of stay. Implications and recommendations for successful restorative care will be discussed.

Prevalence of Symptoms and Quality of Life Among Jordanian Cancer Patients

In Jordan, little is known about cancer-related symptoms prevalence, severity, and its impacts on patients’ quality of life. Therefore, this study was conducted to estimate cancer-related symptoms prevalence, severity, and predictors of quality of life of cancer patients in Jordan. A descriptive cross-sectional survey design was used. The sample consisted of 498 Jordanian cancer patients. There were slightly more males (51.6%) and a mean age of 44.3 ( SD = 15.3) years. The mean of the number of symptoms reported by patients was 11 ( SD = 3.3). The most prevalent symptoms were fatigue (92.5%), feeling drowsy (87.1%), lack of appetite (86.3%), being distressed (86.1%), and pain (85.5%). Furthermore, Jordanian cancer patients had low mean total scores for quality of life at a level of 18.5 ( SD = 4.9). A comprehensive palliative care program is recommended, led by a representative from the Ministry of Health, to integrate palliative care within the current health care system in Jordan.

Spiritual well-being among outpatients with cancer receiving concurrent oncologic and palliative care

PURPOSE

Spiritual well-being is threatened by cancer, but its correlation with other illness symptoms and the efficacy of palliative care (PC) to ameliorate spiritual suffering are not well understood.

METHODS

We conducted a retrospective study using a convenience sample of oncology patients at a comprehensive cancer center who received concurrent oncologic and palliative care between 2008 and 2011 and completed ESAS, QUAL-E, and Steinhauser Spiritual well-being survey questions was conducted. Descriptive, correlation, and t test statistics.

RESULTS

Eight hundred eighty-three patients surveyed had an average age of 65.6 years, with 54.1 % female, 69.3 % white, and 49.3 % married. Half (452, 51.2 %) had metastatic disease. Religious affiliation was reported as Christian by 20.3 %, Catholic by 18.7 %, and "none" by 39.0 %. Baseline spiritual well-being was not significantly correlated with age, gender, race, cancer stage, marital status, insurance provider, or having a religious affiliation. Greater spiritual well-being was correlated with greater quality of life (<p = 0.001) and well-being (<p = 0.001), and with less depression (<p = 0.001), anxiety (<p = 0.001), fatigue (p = 0.005), and pain (p = 0.01). In multiple regression analysis, the associations persisted between spiritual well-being and anxiety, depression, fatigue, and quality of life (R (2) = 0.677). Spiritual well-being improved comparing mean scores immediately prior to initial PC consultation with those at first follow-up (2.89 vs. 3.23 on a 1-5 scale, p = 0.005).

CONCLUSIONS

Among patients with cancer receiving concurrent oncologic and palliative care, spiritual well-being was not associated with patient age, gender, or race, or disease stage. It was correlated with physical and emotional symptoms. Spiritual well-being scores improved from just prior to the initial PC consultation to just prior to the first PC follow-up visit.

A pre-operative nomogram for decision making in oncological surgical emergencies

BACKGROUND

The purpose of the study was to propose a clinical decision-making tool for predicting mortality in patients undergoing emergency abdominal surgery with a palliative intent in the oncology setting.

METHODS

Identification of all emergency surgical procedures performed in a Department of Oncologic Surgery in a Comprehensive Cancer Center between January 2008 and January 2013. Multivariate logistic and Cox regression models were used to identify factors predicitve of mortality at 3 months and survival probabilities. Models were internally validated using bootstrapping and calibration.

RESULTS

The mortality rates were 30% at 1 month, 46.7% at 3 months and 83.3% at the end of the study. One model based on the albumin level and the P-POSSUM score (AUC: 0.725) adequately predicted mortality at 3 months. A survival nomogram predicted mortality with a concordance index (CI) of 0.718, using the following factors: WHO performance status (P = 0.02), albumin level (P < 0.01) and P-POSSUM score (P < 0.01). The origin or the extent of the carcinoma did not own sufficient pronostic impact to be selected in this model.

CONCLUSIONS

Pre-operative mortality risk scores can be developed in a palliative context. Physicians counselling and surgical decision making should be based on the use of these tools.
