Despite our growing knowledge about the pathomechanisms of cancer cachexia, a whole clinical picture of the cachectic patient is still missing. Our objective was to evaluate the clinical characteristics in cancer patients with and without cachexia to get the whole picture of a cachectic patient.
Cancer patients of the University Clinic “Klinikum rechts der Isar” with gastrointestinal, gynecological, hematopoietic, lung and some other tumors were offered the possibility to take part in the treatment concept including a nutrition intervention and an individual training program according to their capability. We now report on the first 503 patients at the time of inclusion in the program between March 2011 and October 2015. We described clinical characteristics such as physical activity, quality of life, clinical dates and food intake.
Of 503 patients with cancer, 131 patients (26.0%) were identified as cachectic, 369 (73.4%) as non-cachectic. The change in cachexia were 23% reduced capacity performance (108 Watt for non-cachectic-patients and 83 Watt for cachectic patients) and 12% reduced relative performance (1.53 Watt/kg for non-cachectic and 1.34 Watt/kg for cachectic patients) in ergometry test. 75.6% of non-cachectic and 54.3% of cachectic patients still received curative treatment.
Cancer cachectic patients have multiple symptoms such as anemia, impaired kidney function and impaired liver function with elements of mild cholestasis, lower performance and a poorer quality of life in the EORTC questionnaire. Our study reveals biochemical and clinical specific features of cancer cachectic patients.
KeywordsCancer cachexia Clinical parameters Clinical picture
Ongoing cachexia represents a significant factor affecting the quality of life and prognosis of cancer patients. Cachexia is present in up to 40% in early stages of patients with gastrointestinal cancers and may be involved in up to 80% cancer deaths. However, it is still difficult to identify cachectic patients, as 40–60% of cancer patients are overweight or obese, even in advanced cancer .
But what do we know about clinical features of cachexia patient?
Cachectic patients usually but not always demonstrate lower body mass index (BMI), which is associated with an increased risk of tumor progression [2, 3]. At the same time, other groups report that BMI is not a prognostic factor for cancer cachexia in a cohort of patients with 17% obese, 35% overweight, 36% normal weight, and 12% underweight persons . Cancer cachectic patients experience numerous complications including reduced effectiveness of chemotherapy [5, 6], reduced mobility, and reduced functionality of muscle-dependent systems, such as the respiratory and cardiovascular systems, leading to decreased quality of life and survival [7–9]. Especially in older population, cancer cachexia clinical features are key predictors of one-year mortality . There is a strong correlation between decreased quality of life scores and decreased physical activity, which is strongly related to weight loss . It was demonstrated that cachectic patients present lower protein, albumins, and hemoglobin levels .
Notably, cachexia is not an incurable situation. The important message is that weight-losing patients with unresectable pancreatic cancer can attenuate their weight loss after eight weeks of intensive nutrition intervention, and weight stabilization is associated with prolonged survival and improved quality of life . However, despite our growing knowledge about the pathomechanisms of this symptom complex, a whole picture of the cachectic patient is still missing.
Some studies aim to define diagnostic criteria of cancer cachexia . Usually, diagnostic tools for cachexia include loss of weight and lean body mass, fatigue, anorexia, reduced physical performance (for example, total activity or 6-min walk distance) and biochemical abnormalities of c-reactive protein (CRP), albumin, and protein.
The existing concepts for the therapy of cachexia are focusing either on nutrition or physical activity. Therefore we founded a nutrition and exercise center for cancer patients in which we are focusing on the definition of the cachectic patient and combined treatment of cancer cachexia with numerous therapy options. Our aim was to evaluate the clinical characteristics such as physical activity, quality of life, clinical dates and food intake in patients with and without cachexia to get the whole picture of a cachectic patient.
From March 2011 cancer patients of the University Clinic, “Klinikum rechts der Isar” with gastrointestinal (GI), gynecological, hematopoietic, lung and some other tumors were offered the possibility to take part in the treatment concept including a nutrition intervention and an individual training program according to their capability. We now report on the first 503 patients at the time of inclusion in the program. All parameters like physical capability, daily calorie intake or selected lab values were documented in a prospectively designed database.
The exact definition of cachexia is a debatable issue in medical literature (reviewed in ). We used the definition of malnutrition proposed by ESPEN (the European Society for Clinical Nutrition and Metabolism) Consensus Statement using following criteria :
BMI <20 kg/m2 if <70 years of age, or <22 kg/m2 if > 70 years of age or
FFMI (fat-free mass index) <15 and 17 kg/m2 in women and men, respectively.
Our definition of cachexia was also according to Fearon and co-workers  and is used by other researchers . Here, the patients are defined as having cachexia, either when they show a weight loss of 5% during the last six months, or a weight loss of 2–5% in combination with a BMI < 20, or a weight loss of 2–5%, together with the presence of sarcopenia. Sarcopenia was defined according to a report of the European working group on sarcopenia in older people (EWGSOP) using first criterion (low muscle mass) plus either second criterion (low muscle strength) or third criterion (low muscle performance) [19, 20].
Blood tests (red blood cells and white blood cells counts, platelets, hemoglobin concentrations), serum electrolytes, serum creatinine, c-reactive protein (CRP), liver function tests (aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, serum bilirubin, and cholinesterase), coagulation tests, and serum albumin levels are routinely performed upon admission to the clinic.
Endurance capacity, maximal power output (POmax) and peak oxygen uptake (VO2peak) were measured as described  in a submaximal incremental exercise test on a computer-controlled bicycle ergometer. A stepwise incremental exercise protocol was applied starting at 25 or 50 watts with increments of 25 watts every three minutes until volitional exhaustion or medical reasons for exercise termination were reached. The exercise was terminated prematurely in the case of significant ECG abnormalities, severe dyspnea or excessive blood pressure increase to more than 230 mmHg systolic and/or less than 110 mmHg diastolic.
Spirometry provided a measurement of the forced vital capacity (FVC) and the forced expiratory volume at the end of the first second of forced expiration (FEV1).
Quality of life and mental health
Health-related quality of life (HRQoL) is important parameter which can predict survival. It was assessed with the 36-Item Short Form Health Survey SF-36 survey and EORTC QLQ-C30. The EORTC QLQ-C30 is a HRQoL measure specific to cancer, whereas the SF- is a generic measure [22, 23]. The EORTC QLQ-C30 is a cancer-specific measure that can capture patients’ functional status in several domains (physical, psychological, and social), their global health status/quality of life (QoL), and symptom severity [22, 23].
The Hospital Anxiety and Depression Scale (HADS) was used for identifying distress. There are two subscales: depression (HADS-D) and anxiety (HADS-A). The optimal cut-off point is to be ⩾8 for the identification of suspicious cases and ⩾11 for safe cases on both subscales, with a sensitivity and specificity of 0.80 on an average . With a score of ⩾13, it is possible to detect 76% of the cases among cancer patients with a specificity of 0.60, whereas 95% of the cases can be detected with a score of ⩾6 (specificity 0.21) .
Nutritional risk screening (NRS)
A diet record was performed to register food intake (number of meals, calories intake/day, number and kind of additional nutrition) as described .
Role of the funding source
The study was in part supported by Nutricia.
Results are expressed as median values. Statistical analyses were performed using the SPSS (version 23, SPSS Inc., Chicago) software package. Two-sided tests and a significance level of 0.05 were used. Values were compared by Mann–Whitney U test for independent samples.

Liver function and parameters of protein synthesis
Two cholestasis enzymes, alkaline phosphatase (ALP) and gamma glutamyl transpeptidase (GGT), were significantly increased in cancer patients with cachexia (Table 3). The parameters of hepatocyte integrity, aspartate aminotransferase (AST) and alanine aminotransferase (ALT), were not changed. Markers of liver synthesis function cholinesterase (CHE), serum albumin and serum protein, were significantly decreased (p < 0.001). Totally, 187 patients (37% of all study participants) received chemotherapy at the moment of inclusion in this study, 63 (33.7%) in cachexia group (this information was not available in 2 of patients) and 124 (66.3%) patients in non-cachexia group (this information was not available in 4 patients). A significant correlation was seen between AP and current chemotherapy (r = 0.258, P < 0.001), GGT and current chemotherapy (r = 0.205, P < 0.001), as well as CHE and current chemotherapy (r = − 0.182, P < 0.001). 66 (50.4%) cachexia and 245 (66.4%) non-cachectic patients did not receive chemotherapy at the moment of inclusion in this study. In this group there is still a significant difference between cachexia and non-cachexia regarding AP (p < 0.001), CHE (p < 0.001), Quick (p < 0.05) and serum albumin (p < 0.001) but not in case of GGT (p = 0.154).

Our study demonstrated that cancer cachectic patients have multiple symptoms such as anemia, impaired kidney function and impaired liver function along with elements of mild cholestasis. Cachexia patients have low level of protein and albumin. As a result significantly more extracellular water and less intracellular water, compared to patients without cachexia. This means that not only low calories but also low oncotic pressure because of low protein play an important role in weight loss in cachectic patients. In parallel to protein deficiency, cachectic patients have lower performance parameters. The low levels of serum albumin, hematocrit, and fibrinogen are well-known for cachectic patients but probably not specific. Furthermore, the performance status of cachectic patients – measured by ergometry - was significantly reduced, leading to a poorer quality of life in the EORTC questionnaire (Fig. 3).
Fearon and co-workers described a population consisting of 170 advanced pancreatic cancer cachectic patients using Karnofsky Performance Score, grip strength, dietary intake, quality-of-life assessment with EuroQol EQ-5D and QLQ-C30, CRP, and CA19-9, but they were mostly concentrated on evaluation whether a 3-factor profile incorporating weight loss, low food intake, and systemic inflammation might relate better to a patient’s overall prognosis than will weight loss alone . Wallengren and co-workers report on 405 patients about cachexia criteria like body mass index (BMI), weight loss, fatigue, Karnofsky performance score, physical function measured on a treadmill, low handgrip strength, lean tissue depletion (DXA or arm muscle circumference), quality of life measured by QLQ-C30 and abnormal biochemistry (inflammation, anemia, or low serum albumin) . The biggest data set with 8160 patients was reported by Martin and co-workers , but the authors were mainly focused on BMI and % weight loss about overall survival to develop a grading system. Takayama and co-workers analyzed 406 stage IV NSCLC patients using handgrip strength, quality of life, Karnofsky Performance Scale, biochemical parameters (white blood cell count, hemoglobin, protein, albumin, triglycerides, calcium, CRP, and Insulin-like growth factor-1) and survival . In the study of Theresen and co-workers 77 patients with advanced colorectal carcinoma were described using clinical parameters such as energy intake, the skeletal muscle mass cross-sectional area, a tool for assessing nutritional status the Subjective Global Assessment (SGA), protein, albumin and CRP .
In our study population, the median hemoglobin was 12 g/dl and mean hemoglobin was 11.8 ± 1.5 g/dl. Our data regarding anemia in cachectic patients are by other groups. It was additionally reported using univariate Cox proportional hazard regression that hemoglobin was significantly associated with mortality risk . According to CACHEXIA score of Argiles and co-workers , a tool for staging cachectic patients, hemoglobin in cachectic patients should be below 12 g/dl.
Serum albumin und protein values
Although we observed hypoalbuminemia and hypoproteinemia in cachectic patients, these changes were not severe. Additionally, we observed that calcium level in cachectic patients was lower than in non-cachectic patients. Taking into consideration that half of circulating calcium ions are bound to albumin, this effect resulted probably from hypoalbuminemia. Reasons for hypoalbuminemia are usually decreased synthesis, increased degradation, or an increased transcapillary escape rate . We hypothesize that the primary mechanism was decreased synthesis what is supported through decreased liver synthesis function measured using liver cholinesterase (Table 3). At the same time decreased degradation was not observed because urinary albumin was unchanged (Table 4).
According to Consensus Statement of the European Society of Clinical Nutrition and Metabolism (ESPEN), visceral proteins like serum albumin concentrations that are good indicators of disease severity and outcome should not be used for either screening or diagnosis of malnutrition because of a low grade of nutrition specificity .
In our study there was a significant difference in serum creatinine in cachectic and non-cachectic groups that is by data of another working group , demonstrating that serum creatinine can be a biomarker of skeletal muscle mass in chronic kidney disease. The urinary excretion of enzymes, in particular, N-acetyl-beta-D-glucosaminidase (NAG) and alpha-1-microglobulin, non-invasive parameters of the renal tubular function, were significantly higher in cachectic patients.
Impaired liver function in cachexia
Two cholestasis markers, AP and GGT, were raised in cachectic patients in isolation with normal bilirubin. Though non-liver causes of this elevation like bone metastases, hyperparathyroidism, renal impairment and Paget’s disease are possible, the combination of two markers makes liver problems more likely. One possible explanation is the hepatotoxic effect of the chemotherapy confirmed by the correlation between AP, GGT, CHE and chemotherapy at the time of inclusion. The difference in AP, GGT, CHE between chemotherapy patients and chemotherapy-naive patients were not significant in our study. To our knowledge, elevated cholestasis markers and decreased liver synthesis parameters were not described in cancer cachexia until now. This elevation was mild but present in cachexia in patients under chemotherapy and without chemotherapy. Only for cardiac cachexia, it was demonstrated that 60% of cachectic patients present with abnormal cholestatic parameters . Some authors proposed the importance of the role of liver enzymes in cancer cachexia (reviewed in [33, 34]) when a flow of amino acids from skeletal muscle to the liver occurs and serves for gluconeogenesis and acute-phase protein synthesis. It was suggested that an interaction between the tumor, peripheral blood mononuclear cells, and the liver may play a central role in the development and regulation of cachexia . The important role of the liver in cancer cachexia was proposed by Lieffers and co-workers . They hypothesized that a viscerally driven cachexia syndrome in patients with colorectal cancer originates from an increase in mass of high-metabolic-rate tissues, such as the liver and spleen.
Inflammation parameters (CRP) in cachexia
Increased CRP is supposed to be a valid laboratory and clinical marker in cachexia [5, 14, 37, 38]. Fearon and co-workers proposed that inclusion of a marker of systemic inflammation (e.g., CRP) in a cachexia stratification system could account for patients with real loss of function also perceiving themselves to have reduced function . Though we saw a significant difference in CRP-value between cachexia and non-cachectic patients. This difference (0.1 mg/dl versus 0.2 mg/dl) is non-specific to provide additional information to the clinician when other accessible markers, such as serum hemoglobin or cholinesterase are considered. In spite of some prognostic scores for the assessment and treatment of cancer cachexia, like the Glasgow Prognostic Score (GPS)  or the cachexia score (CASCO) , which are based on CRP and albumin values, we agree with Utech and co-workers who suggest that inflammatory markers may not necessarily improve our ability to predict survival when cancer staging, serum albumin, and weight loss history are available . Additionally, we think that CRP is not necessarily a characteristic parameter in cancer cachexia because it is not routinely measured in clinical practice, in Germany usually only if indicated.
Two parameters of endurance (capacity performance and relative performance) were significantly lower in cachectic patients. The dramatic change in cachexia was 23% reduced capacity performance (108 Watt for non-cachectic-patients and 83 Watt for cachectic patients) and 12% reduced relative performance (1.53 Watt/kg for non-cachectic and 1.34 Watt/kg for cachectic patients) in ergometry test.
Quality of life, mental health and food intake
Our results demonstrated that cachexia leads to a reduced quality of life, but the mental health is still stable. The mean value for global quality of life score was 55.7 ± 20.0 for non-cachectic patients and 47.7 ± 21.6 for cachectic patients, which is worse than the EORTC reference value global score of 61.3 ± 24.2 for all cancer types, and worse than values in other studies (for example, 68.73 ± 19.05 for patients with different cancer types on chemotherapy ).
These data are of special importance because for the EORTC QLQ-C30, both the general health and functioning scales and symptom scales (Dyspnea and Appetite Loss), as well as for the SF-36, role – emotional, general health, energy/vitality, and social functioning significantly predicted survival .
Fearon and co-workers report that weight loss alone (≥10%) did not define a population that differed from self-reported functional aspects of quality of life . With our present study, we were able to demonstrate slight but significant changes in quality of life in cachectic patients without using CRP as a diagnostic parameter for cachexia. This could be explained by the different patient populations (pancreatic cancer patients that were not considered suitable to receive systemic chemotherapy in the study of Fearon and co-workers, and patients with mixed cancers in our population).
It is supposed that a reduction in food intake is common in patients with progressive cancer and cachexia. Dysphagia, nausea, xerostomia and changes in taste and smell may lead to diminished food intake and thereby insufficient energy intake (reviewed in ). Our data show that weight loss didn’t depend on calories because cachectic patients know their problem and eat appropriately after a medical recommendation. Additionally, doctors recognize the problem of under-nutrition and prescribe parenteral nutrition (in 12.3% of patients in our cohort of cachectic patients). Tsoli and colleagues confirm our result in murine model and report that not only reduced food intake but dysregulated expression of transcription factors that control lipid metabolism and thermogenesis in brown adipose tissue lead to weight loss during the development of cachexia . So, despite the same amount of meals per day, patients with cachexia had a reduced calorie intake.
One potential limitation of this study was the observational design, so there may be bias inherent in who ultimately was referred to our nutrition-exercise center or decided to participate in the study. Totally, 187 (37%) patients received chemotherapy at the moment of inclusion in this study. This fact could influence the characteristics of patients. The patients are inhomogeneous regarding the type of cancer. However, future studies should be done in more homogenous cancers patient populations.
Our study reveals biochemical and clinical specific features of cancer cachectic patients. The positive feature of our study is that it was conducted on large study groups (369 patients without cachexia and 131 patients with cachexia).
We were able to demonstrate that the problem of cachectic patients is not the calorie intake but protein turnover and maybe disorder in fat metabolism. Therefore we postulate that cachectic patients should be treated as high-risk patients and propose that after diagnosis of cachexia the patients should be presented to a cachexia team including “leading doctor” (for, example a surgeon, oncologist or internist, who supervises the treatment), nutritional specialist, clinical pharmacist, sports scientist and psychiatrist.
