RESUMO

OBJECTIVES: The aim of this study is to evaluate pain management adequacy based on the Pain Management Index (PMI), and its association with the Brief Pain Inventory (BPI) in advanced cancer inpatients to a palliative care unit. METHODS: This is a quantitative study concerning advanced cancer inpatients in a specialised palliative care unit between June 2021 and February 2022. The BPI was applied, and analgesia was observed on the first (D1), third (D3) and seventh (D7) day of hospitalisation. Adequate analgesia was considered when PMI≥0. RESULTS: A total of 104 patients were evaluated on D1, 68 on D3 and 45 on D7, with a mean age of 53.6 years (SD±14.1), most of them female (65.4%), with the most frequent primary tumour site located in the gastrointestinal tract (22.1%). The observed analgesia was adequate (PMI≥0) in 52.9% of all patients on D1, 95.6% on D3 and 100% on D7 (p value=0.012). The number of patients with moderate to severe pain interference in general activities (p value 0.012), mood (p value 0.014), walking ability (p value 0.047), normal work (p value 0.038) and pleasure of living (p value 0.025) decreased during hospitalisation. CONCLUSIONS: Pain is a prevalent and impacting symptom in patients undergoing palliative care. Thus, objective analgesic adequacy assessments in specialised services are required. These findings reinforce the importance of effective pain control and corroborate the importance of employing objective tools in evaluating medical services and improving quality of life of patients.

RESUMO

Nutritional screening and assessment are considered essential steps in nutritional care for cancer patients, malnutrition remains underreported in clinical practice. The aim of this study was to analyse the clinical usefulness of the Patient-Generated Subjective Global Assessment short form (PG-SGA SF©) for nutritional screening in patients with head and neck cancer (HNC). This is a multicentre, cross-sectional study involving patients with HNC. The final score of the PG-SGA SF© was obtained and the nutritional status was diagnosed using the Patient-Generated Subjective Global Assessment (PG-SGA)®, classifying them as well-nourished or malnourished. Receiver operating characteristic curve, ordinal logistic regression, and C-statistic were used. In total, 353 patients with HNC were enrolled and the prevalence of malnutrition, according to the PG-SGA®, was 64.02% and the median final score of PG-SGA SF© was 11 points. The final score of the PG-SGA SF© had high accuracy (area under the curve = 0.915), and scores ≥9 had the best performance in diagnosing malnutrition. PG-SGA SF© final score ≥9 was associated with malnutrition (odds ratio = 28.32, 95% confidence interval= 15.98-50.17), with excellent discriminatory power (C-statistic = 0.872). In conclusion, the PG-SGA SF© demonstrated excellent performance for nutritional screening in patients with HNC. Given that it is a simple instrument that is faster to administer than the PG-SGA®, we recommend its use in clinical practice among such patients.

RESUMO

OBJECTIVES: This study aimed to explore factors associated with skeletal muscle radiodensity (SMD) variability in patients with metastatic cancer. METHODS: This study included 393 patients (median age 61 y, 70% women) who had computed tomography (CT) scans within 30 days of inclusion in the study. SMD was evaluated from CT by averaging the Hounsfield unit value of the total muscle area. Skeletal muscle index (SMI), visceral adipose tissue index (VATI), subcutaneous adipose tissue index (SATI), and total adipose tissue index (TATI) were also assessed by CT. Additionally, age, sex, race/skin color, disease characteristics, comorbidities, inflammatory markers, handgrip strength (HGS), and body mass index (BMI) were recorded and evaluated in the linear regression analysis to identify factors associated with SMD variability. RESULTS: Multivariate explanatory models having SMD as an independent variable were performed and included BMI (model 1, r2 = 0.699), TATI (model 2, r2 = 0.712) or VATI and SATI (model 3, r2 = 0.706) in addition to age, race/skin color, tumor site, kidney disease, serum albumin, HGS, and SMI as dependent variables. For all models, lower SMD was associated with higher age, BMI, and adiposity measurements, kidney disease, White race/skin color, and lower serum albumin, HGS, and SMI. The primary tumor site also contributed to changes in SMD in all models, specifically those located in the gastrointestinal tract, gynecologic, and bone and connective tissue. CONCLUSION: In this group of patients with metastatic cancer, lower SMD was associated with older age, White race/skin color, and an overall worse clinical condition.

RESUMO

OBJECTIVES: To develop and validate a new prognostic model to predict 90-day mortality in patients with incurable cancer. METHODS: In this prospective cohort study, patients with incurable cancer receiving palliative care (n = 1322) were randomly divided into two groups: development (n = 926, 70%) and validation (n = 396, 30%). A decision tree algorithm was used to develop a prognostic model with clinical variables. The accuracy and applicability of the proposed model were assessed by the C-statistic, calibration and receiver operating characteristic (ROC) curve. RESULTS: Albumin (75.2%), C reactive protein (CRP) (47.7%) and Karnofsky Performance Status (KPS) ≥50% (26.5%) were the variables that most contributed to the classification power of the prognostic model, named Simple decision Tree algorithm for predicting mortality in patients with Incurable Cancer (acromion STIC). This was used to identify three groups of increasing risk of 90-day mortality: STIC-1 - low risk (probability of death: 0.30): albumin ≥3.6 g/dL, CRP <7.8 mg/dL and KPS ≥50%; STIC-2 - medium risk (probability of death: 0.66 to 0.69): albumin ≥3.6 g/dL, CRP <7.8 mg/dL and KPS <50%, or albumin ≥3.6 g/dL and CRP ≥7.8 mg/dL; STIC-3 - high risk (probability of death: 0.79): albumin <3.6 g/dL. In the validation dataset, good accuracy (C-statistic ≥0.71), Hosmer-Lemeshow p=0.12 and area under the ROC curve=0.707 were found. CONCLUSIONS: STIC is a valid, practical tool for stratifying patients with incurable cancer into three risk groups for 90-day mortality.

RESUMO

OBJECTIVE: To report the experience of offering the Quality End of Life Care for All (QELCA) Programme, highlighting the distinct methodology for the training of health professionals. DEVELOPMENT: The QELCA Programme, intellectual property of St Christopher's Hospice, was offered to seven health professionals working in the hospital palliative care unit at the National Cancer Institute, between June and December 2022, with the support of Premier Institute. The programme, which originates in the UK, has been evaluated there and is currently being evaluated in Hong Kong, and is delivered in two phases: (1) a 5-day immersion programme; (2) monthly sessions of Action Learning for 6 months. Participants realised that communication between members of the multidisciplinary team, as well as between health professionals and patients/loved ones, was one of the key challenges for achieving quality of death in the hospital palliative care unit. This insight empowered them to drive forward significant changes in practice that promise to improve quality of care. CONCLUSION: The QELCA Programme enabled participants to engage in active problem-solving to promote the relief of suffering of patients and their families in end-of-life care.

RESUMO

The objective of this study was to evaluate the impact of fasting easing on laboratory measurements of the lipid profile, in order to contribute to the fidelity of interpretation of laboratory results. Starting in October 2022, a Systematic Literature Review (SRL) was carried out, using articles indexed in the electronic databases PubMed/MEDLINE, EMBASE, Scopus, LILACS and Cochrane Library, following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes Group (PRISMA). This RSL was registered with PROSPERO, under registration number CRD42022370007. For inclusion, articles had to be original and developed in humans. After evaluating the methodological quality and analyzing the risk of bias, we obtained 16 articles published between 1994 and 2021, providing data on a total of 398,709 individuals, aged between 3 and 93 years. According to the selected studies, lipid profile measurements performed with flexible fasting, in addition to bringing benefits to patients and the pre-analytical system of the clinical laboratory, are more suitable for determining cardiovascular risk, mainly through the assessment of values obtained in the determination of triglycerides. It is therefore concluded that the optional use of fasting must be established through medical advice. In addition, laboratory methods and readings must be readjusted to this reality, informing through the report the parameters related to the lipid profile with and without the use of a 12-hour fast.

RESUMO

BACKGROUND: Nutritional support (NS) offered through oral nutritional supplements (ONS) or enteral nutrition (EN) and its impact on quality of life (QoL) is a controversial topic in patients with cancer receiving palliative care (PC). AIMS: To compare the QoL of patients without and with use of NS, including ONS or EN in patients with incurable cancer receiving PC. METHODS: Cross-sectional analysis with patients that were evaluated at PC Unit between June 2021 and February 2023. QoL was assessed using the Quality of Life Questionnaire Core 15. Patients were classified into three groups according to the NS: ONS (n=72; 33%), EN (n=61; 28%) and control group (CG) (n=87; 39%), the last one being formed by patients not using NS. Adjusted logistic regression models were used to verify the association of the domains of QoL with the type of NS. RESULTS: A total of 220 patients were included, with a median age of 64 (58-70) years, predominantly male (54.1%). The EN group had worse scores in physical function when compared with the ONS group (p=0.037) and appetite loss when compared with the CG (p=0.013). The ONS (OR: 2.70; 95% CI 1.32 to 5.49) and EN groups (OR: 2.61; 95% CI 1.24 to 5.49) were independently associated with a higher chance of presenting appetite loss in relation to the CG. CONCLUSION: In general, there was no difference in the QoL of patients using NS when compared with patients not using NS. However, patients using NS have more chance of having appetite loss.

RESUMO

BACKGROUND: Cachexia is associated with increased morbidity and mortality rates in patients with cancer. This meta-analysis aims to explore the effect of anamorelin on cancer cachexia markers. METHODS: We searched MEDLINE/PubMed, SCOPUS, and WOS from their inception until 5 June 2022. A systematic search was conducted according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) guidelines. We included trials investigating the effect of anamorelin on body weight, lean body mass, fat mass, insulin-like growth factor 1 (IGF-1), handgrip, quality of life insulin-like growth factor-binding protein 3 (IGFBP-3), and in patients with cancer. A random-effects model was run to pooled results. RESULTS: Five articles providing 1331 participants were analyzed in this study. Pooled analysis revealed a significant increase in body weight (weighted mean difference (WMD): 1.56 kg, 95% confidence interval (CI): 1.20, 1.92; I2= 0%), lean body mass (WMD: 1.36 kg, 95% CI: 0.85, 1.86; I2= 53.1%), fat mass (WMD: 1.02 kg, 95% CI: 0.51, 1.53; I2= 60.7%), IGF-1 (WMD: 51.16 ng/mL, 95% CI: 41.42, 60.90, I2= 0%), and IGFBP-3 (WMD: 0.43 µg/mL, 95% CI: 0.17, 0.68, I2= 98.6%). Results showed no significant increase in appetite when analysis run on all studies without considering different doses 0.29 (95% CI: -0.30, 0.89, I2= 73.8%), however, there was a significant increase in appetite without heterogeneity and inconsistency 0.59 (95% CI: 0.32, 0.86; I2= 0%) in the 100 mg/day group compared to anamorelin non-user. CONCLUSIONS: Patients with cancer who receive anamorelin as a treatment for cachexia showed a significant increase in body weight, lean body mass, fat mass, IGF-1, and IGFBP-3.

RESUMO

INTRODUCTION: Cancer pain is one of the most prevalent manageable symptoms in patients with advanced cancer, and it has a negative impact on quality of life (QoL). OBJECTIVE: The aim of this study is to examine the correlation between cancer pain and QoL in patients with advanced cancer who are hospitalized in a palliative care unit. METHODS: This study is a cross-sectional analysis of patients with advanced cancer who were hospitalized with cancer pain at a specialized palliative care unit between June 2021 and February 2022. Pain intensity and its impact on daily activities were assessed using the Brief Pain Inventory (BPI), while the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core 15 PAL (QLQ-C15-PAL) was used to evaluate QoL. RESULTS: A total of 104 patients with cancer pain were included, with a mean age of 53.6 years (±14.1). Most of the patients were female (65.38%), and the most common primary tumor site was in the gastrointestinal tract (22.11%). The most frequently reported site of cancer pain was the abdomen (32.69%). The mean duration of cancer pain was 52.3 days (±6.2). The domains of QoL most strongly correlated with cancer pain were weakness (coefficient = .52, P < .001), nausea (coefficient = .36, P < .001), and the physical domain (coefficient = -.30, P < .001). CONCLUSION: Cancer pain is strongly correlated with a deterioration in QoL in patients with advanced cancer, and its management should be pursued as a strategy for optimizing QoL.

RESUMO

OBJECTIVES: This study aimed to identify the clinical usefulness of assessing nutritional status using validated tools for the indication of enteral nutrition for patients with incurable cancer in palliative care. METHODS: In this prospective cohort study, patients were assessed for nutritional risk using the Patient-Generated Subjective Global Assessment and for cancer cachexia (CC) using the modified Glasgow Prognostic Score upon enrollment and after ∼30 d. The outcome was stable or improved Karnofsky Performance Status. Logistic regression models were used, providing the odds ratio (OR) and 95% confidence interval (CI). RESULTS: A total of 180 patients participated. The only nutritional status parameter that was associated with function was CC. The less severe the CC, the more likely Karnofsky Performance Status was to remain stable or improve over 30 d (non-cachectic: OR = 1.95; 95% CI, 1.01-3.47; malnourished: OR = 1.06; 95% CI, 1.01-1.42). Furthermore, white skin color (OR = 1.79; 95% CI, 1.04-2.47), higher educational level (OR = 1.39; 95% CI, 1.13-2.78), and inadequate calorie intake (OR = 1.96; 95% CI, 1.02-2.81) were also associated with the outcome. CONCLUSIONS: Using the modified Glasgow Prognostic Score to identify the existence and severity of CC, which is associated with function, has the potential to help clinical decision making concerning the indication of enteral nutrition in patients with incurable cancer receiving palliative care.

RESUMO

AIM: This study evaluated the association between risk of malnutrition and performance status, and mortality in hospitalized breast cancer patients. METHODS: Prospective cohort study with hospitalized breast cancer patients evaluated at a referral Cancer Center. The Risk of malnutrition was assessed by the Patient-Generated Subjective Global Assessment (PG-SGA) and performance status was determined using the Eastern Cooperative Oncology Group Performance Status Scale (ECOG PS). Logistic regression was used to analyze the factors associated with death, using the odds ratio (OR) with a 95% confidence interval (CI) as an effect measure. RESULTS: A total of 195 woman were included, with a mean age of 56.3 (±12.6) years. Patients with an overall PG-SGA score ≥18 (OR: 2.11; 95% CI: 1.03-4.62) and ECOG PS ≥ 3 (OR: 3.34; 95% CI: 1.48-7.52) had a higher occurrence of death during hospitalization, regardless of age or disease stage. The concomitant presence of these two factors improved the accuracy of the association (OR: 5.32; 95% CI: 3.11-9.76) and showed good predictive accuracy (C-statistics: 0.77). CONCLUSION: Nutritional risk and poor performance status were associated with a higher occurrence of death in women with breast cancer. The use of these two indicators improves their predictive accuracy for mortality.

RESUMO

Objective(s): To develop a questionnaire that assesses the level of comprehension and decision-making capacity of patients with breast cancer about palliative care and advance care planning. Methods: Questionnaire items were based on the scientific literature. Delphi Consensus, a three-round survey with experts (n = 14), evaluated the relevance, clarity, and redundancies of the items. A pretest with breast cancer patients (n = 15) evaluated whether they comprehended each item and identified doubts or discomforts. Results: The initial questionnaire was composed of 38 items. After the Delphi, 18 items were restructured, six were added, and 16 were removed. In the pretest phase, all items with the survey header, guidelines, and Likert model were evaluated. All items accomplished ≥80% cut-off score and were kept as in the original version. The final version of the questionnaire have 28 itens and five domains: determination, responsibility, independence, self-knowledge, and knowledge of reality. Conclusions: This study represents the first step in the development of a questionnaire that may be used in oncology clinical practice. The main findings revealed that Delphi and pretesting increased the quality of the questionnaire, making it compelling to assess breast cancer patients' comprehension and decision-making capacity about PC and ACP.

RESUMO

OBJECTIVE: To evaluate current evidence of the effect of specialised nutritional interventions on nutritional status, survival, quality of life and measures of functionality in patients with incurable cancer. METHODS: Systematic literature review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed/MEDLINE, EMBASE, Scopus, LILACS and Cochrane Library databases. Clinical studies that evaluated different specialised nutritional interventions, such as nutritional counselling, oral nutritional supplementation (ONS), enteral nutrition (EN) and parenteral nutrition (PN), were eligible. Only studies classified as being of high methodological quality (ie, low or moderate risk of bias) were included. RESULTS: A total of 22 studies reporting on 2448 patients were deemed eligible. Five types of specialised nutrition were observed: mixed (multimodal nature, ie, dietary counseling, ONS, physical activity and/or drugs) (n=12), ONS (n=5), PN (n=3), EN (n=1) and multidisciplinary team counselling (n=1). Benefits of any kind from the interventions were reported in 14 (63.6%) studies, mainly resulting from mixed intervention. Nutritional status improved in 12 (60.0%) of 20 studies and quality of life improved in eight (50.0%) of 16 studies. Few studies have evaluated the influence of nutritional interventions on survival and measure of functionality, and have not shown improvement in these outcomes. CONCLUSION: Despite the limited evidence, specialised nutritional interventions can yield positive effects for patients with incurable cancer, mainly in their nutritional status and quality of life.

RESUMO

BACKGROUND & AIMS: The study aimed to evaluate the effect of muscle mass, alone and combined with muscle strength, in predicting survival in patients with incurable cancer. Muscle mass was assessed by computed tomography (CT). METHOD: Low muscle mass and low muscle strength was defined, respectively, by skeletal muscle index (SMI) assessed by CT and handgrip strength (HGS) below the first tertile of the studied sample, as follow: SMI < 41.3 or < 34.9 cm2/m2 (male/female) and HGS < 20 or < 13 kg (male/female). Kaplan Meier curves, and Cox-regression models were applied to analyze overall survival (OS) outcomes. RESULTS: A total of 386 patients were included, and the median OS was 43 [interquartile range (IQR): 15-96] days. Considering the appropriate SMI and HGS as the reference group, a significantly lower OS was observed in the group with low SMI + low HGS [54 (IQR: 38-69) versus 22 (IQR: 10-33) days; p < 0.001]. Patients with low HGS alone presented lower OS than those of the appropriate group [52 (IQR: 42-61) versus 24 (IQR: 17-30) days; p < 0.001], but no differences were observed in the groups with low SMI alone versus appropriate [46 (IQR: 35-56) versus 40 (IQR: 30-49) days; p = 0.365]. The adjusted Cox regression demonstrated that low HGS alone [hazard ratio (HR): 1.51; 95% confidence interval (CI): 1.20-1.91] and low SMI + low HGS group (HR: 1.77; 95% IC: 1.28-2.44) had higher risk of 180-day mortality. Muscle mass combined with muscle strength improved OS prediction compared to these measurements alone in patients with incurable cancer.

RESUMO

BACKGROUND: The Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF) is a standardized tool for assessing nutrition risk in patients with cancer. The aim of this study was to propose and validate a cutoff point for the PG-SGA SF related to the prognosis of patients with incurable cancer in exclusive palliative care. METHODS: This is a prospective cohort study of patients with incurable cancer at the National Cancer Institute in Brazil. A total sample (n = 2,144) was randomly divided into groups: (1) training (n = 1,072), to determine the most accurate PG-SGA SF cutoff, and (2) validation (n = 1,072), to test the predictive accuracy of this cutoff point. The receiver operating characteristic curve was plotted to determine the best cutoff point of the PG-SGA SF related to death. Concordance statistics (C statistic) were used to test the predictive accuracy of the models. Kaplan-Meier curve and the Cox hazard model were used to verify a prognostic value of the cutoff point. RESULTS: PG-SGA SF score ≥15 was found to be the best cutoff based on 90-day mortality with good accuracy discrimination (C statistic ≥ 0.74). Patients whose PG-SGA SF score was ≥15 had a shorter survival of 32 (interquartile range [IQR], 12-75) vs 83 days (IQR, 31-90) (p-value < .001) and higher risk of death (hazard ratio: 2.20; 95% CI, 1.64-2.95). CONCLUSIONS: The proposed PG-SGA SF cutoff score is valid and, alongside its usefulness in nutrition triage, could provide prognostic value for patients with incurable cancer.

RESUMO

BACKGROUND/OBJECTIVES: Handgrip strength (HGS) is a potential predictor of outcomes in cancer setting. However, reference values for this population are lacking. The study aimed to describe reference values and cutoff point for HGS in adults with incurable cancer in Brazil and to verify the association of reference values with prognostic. METHODS: Secondary analysis of a prospective cohort, conducted with 1,868 patients at the National Cancer Institute in Brazil were analyzed. HGS (kg) data were obtained with a Jamar® hydraulic dynamometer. Description of percentile values of HGS was stratified by sex and age groups. Receiver operating characteristic curve was performed to determine the optimal HGS cutoff point by sex and age according to performance status. Kaplan-Meier curves was used to analyze the probability of survival and Cox's proportional model used to identify whether HGS predict 180-d mortality. RESULTS: HGS value was significantly higher in male than in female and decreased with increasing age. Sex-specific HGS cutoff values ranged from 32.5 to 24.5 kg in males and 20.5 to 18.5 kg in females (with younger adults stronger than the older ones). When compared to HGS ≥50th, patients with HGS ≤10th percentile had significantly lower survival, as well as patients classified below the HGS cutoff point. In addition, patients with lower HGS percentiles showed increased risk of mortality regardless of sex and age. CONCLUSION: Reference values can inform the clinical assessment of HGS, which is recognized as an important part of the identification of patients with incurable cancer with reduced physical function and short survival.

RESUMO

OBJECTIVE: To assess the frequency and factors associated of the provision of nutrition support (NS) in the last 30 days of life in patients with advanced cancer in the palliative or non-palliative setting. METHODS: Retrospective cohort study in palliative and non-palliative care units at a specialized cancer center for oncology in Brazil. The use of oral nutrition supplements (ONS) and enteral (EN) and parenteral (PN) nutrition in the 30 days before death were assessed. RESULTS: The 239 patients included were predominantly older (>60 years; 63.2%) and female (61.1%). The use of ONS was lower in palliative than non-palliative care during the last 30 (52% vs. 6%), 7 (42% vs. 4%), and 3 (23% vs. 2%) days before death (all P < .001). The use of EN and PN was lower in palliative care, decreasing with the approach of death. The independent factors associated with ONS in non-palliative care were (odds ratio): breast tumor (3.03), hypoalbuminemia (1.10), and nutrition risk (16.98); in palliative care, only the Karnofsky Performance Status (KPS) ≥40% (1.24) was associated to the use of ONS. The use of EN and PN was associated with head-neck (HN) tumor in both settings (5.41) in non-palliative and (8.74) in palliative. Others independent factors were: hypoalbuminemia (3.12) in non-palliative care and KPS (1.31) in palliative care. CONCLUSIONS: The use of NS near the end of life was high in the non-palliative and less frequent in palliative care setting. The factors associated with NS differed according to the clinical oncology setting, with one of the factors in palliative care being a better prognosis.

RESUMO

OBJECTIVES: We aimed (1) to assess the nutritional status (NS) using different methods, according to the primary tumour site and (2) to evaluate the performance of these methods in patients with incurable cancer from a reference centre in Brazil. METHODS: Cross-sectional analysis of data from patients admitted to the palliative care unit of a reference cancer centre in Brazil, between July 2016 and March 2020. The primary tumour site was the independent variable and the NS using different methods were the dependent variables. Logistic regressions were performed. RESULTS: A total of 2,144 patients were included in the study. The most common primary tumour site was the upper gastrointestinal (GI) tract (18.0%), followed by gynaecological (17.6%) and head and neck (HN) (13.5%). Our results showed that patients with tumours of the upper GI tract followed by HN presented significantly higher risk of worse NS. In contrast, breast tumours, bone and connective tissues and melanoma presented inverse association. The gynaecological cancer was variably associated with nutritional impairment, according to the assessment method. CONCLUSIONS: Patients with incurable cancer present high prevalence of NS impairment, depending on the tumour site, shown to be elevated in patients with tumour in the upper GI tract.

RESUMO

OBJECTIVES: Previous attempts to classify cancer cachexia (CC) have demonstrated limitations regarding stages and diagnostic criteria. This study aims to develop and validate a new staging system for CC in patients with incurable cancer. METHODS: This is an analysis of a database from a prospective cohort study of 1325 patients with advanced cancer referred for palliative care between 2016 and 2020. The cohort was randomly divided into two groups: Development (882 patients) and validation (443 patients) sets. A hierarchical cluster analysis was performed to distinguish different stages of CC in the development set. Next, the optimal cutoff points and ideal combinations of the most important factors associated with the CC groups (clusters) were ascertained. Finally, the relationship between the CC stages determined using the new system and body composition, quality of life, and overall survival was verified with the validation set. RESULTS: The new system classified CC into three stages: Precachexia (10.8%), cachexia (57.8%), and refractory cachexia (31.4%), based on a combination of percentage weight loss in the past 6 mo (<15 or ≥15), body mass index (<21.0, 21.0-26.4, >26.4 kg/m2), and mid-upper-arm muscle area (≥38.0/≥35.5 or <38.0/<35.5 cm2 in men/women, respectively). The new staging system enabled a clear classification of patients into three CC groups according to the outcomes analyzed. Outcomes of patients with refractory cachexia were significantly worse than those in the other groups. CONCLUSIONS: This study presents a useful, valid system for CC staging in the clinical setting, and is also capable of predicting outcomes, including quality of life and overall survival.
