Anorexia is a frequent symptom in cancer and we aimed to assess its prevalence among patients at their first cancer diagnosis by different appetite tools and the relationship between each tool with self-reports of food intake. We also tested whether cancer anorexia influences outcomes independently of reduced food intake or body weight loss (BWL) overtime and whether BWL was associated with complications during anticancer-therapy. Functional Assessment of Anorexia/Cachexia Therapy (FAACT) score, self-assessment of appetite, Anorexia Questionnaire (AQ) and Visual Analog Scale (VAS) were administered. Percent of food intake was used as a criterion measure of anorexia. We registered BWL and anticancer-therapy complications over 3-month-follow-up. 438 cancer patients from 7 cancer-centers worldwide were included. The prevalence of anorexia was 39.9% by FAACT score, 40.2% by VAS, 40.6% by the self-assessment of appetite and 65.4% by AQ. Low food intake (≤50%) was reported in 28% of patients. All appetite tools correlated with food intake percent (P < 0.0001). We documented a correlation between self-assessment of appetite, FAACT score, VAS and BWL overtime (P < 0.04). The self-assessment of appetite (P = 0.0152) and the FAACT score (P = 0.043) were associated with BWL independently of anticancer therapies. Among patients with BWL, the risk to develop complications was greater with respect to those who maintained a stable or gained body weight (P = 0.03). In our sample of cancer patients, FAACT score and self-assessment of appetite performed well when low food intake was used as a criterion measure, and revealed an association of anorexia with BWL, which was, in turn, related to the development of anticancer-therapy complications.

Abstract: Purpose: Lung cancer is the most common cause of cancer death. A cumulative prognostic score based on C-reactive protein and albumin, termed the Glasgow Prognostic Score (GPS), indicates the presence of systemic inflammatory response. GPS has been proposed as a powerful prognostic tool for patients with various types of malignant tumors, including lung cancer. The aim of this study was to assess the predictive value of baseline GPS in terms of toxicity and response in lung cancer patients treated with platinum-based chemotherapy. Patients and methods: Patients referred to our institution for consideration of first-line platinum-based treatment were eligible. Demographics and disease-related characteristics were recorded. Toxicity was graded according to NCI CTCAE version 3.0 throughout first-line therapy. GPS was calculated before the onset of treatment and was related to the development of toxicity. Response to first-line therapy and survival data were also collected. Results: Totally, 96 lung cancer patients were accrued. GPS was associated with increased mucositis p =0.004), neurotoxicity (p =0.038), neutropenia (p =0.02), dose reductions or/ and need for granulocyte colony-stimulating factor (G-CSF) support (p =0.005), toxicity-related termination of treatment (p =0.001) and chemotherapy-related toxic deaths (p =0.013). GPS was associated with overall survival (p =0.016) and progression-free survival (p =0.016) as well as response to treatment (p =0.05). Conclusions: Our data demonstrate that GPS assessment is predictive of the most important aspects of platinum-related toxicity and this may partly explain its associations with poor clinical outcome in patients with metastatic lung cancer.

Abstract: Purpose: Lung cancer patients frequently present with weight loss in the context of the cachexia syndrome. Despite its high clinical significance, definite diagnostic criteria of cachexia are lacking. Nutritional screening questionnaires, like the Mini Nutritional Assessment (MNA), have been proposed for the timely diagnosis of the syndrome. The aim of this study was to evaluate the correlation of MNA with laboratory markers of inflammation/cachexia in patients with metastatic lung cancer. The prognostic value of the measured parameters was also examined. Patients and methods: Patients with metastatic lung cancer referred for systemic therapy were eligible. Baseline clinical characteristics were recorded and nutritional status was assessed using MNA. Blood samples were also collected and the following parameters were measured: hemoglobin (Hb), albumin (Alb), C-reactive protein (CRP), ghrelin, adiponectin, leptin and insulin growth factor I (IGF-I). Results: Totally, 115 patients (101 males) [median age 66 years (range 32–86)] were evaluated. According to MNA score, 27 (23.5%) patients were well nourished, 59 (51.3%) were at nutritional risk and 29 (25.2%) were already malnourished at diagnosis. MNA correlated with the following parameters: Hb (p =0.001), albumin (p <0.001), CRP (p =0.002), adiponectin (p =0.037) and leptin (p =0.008). After a median follow up of 38.2 months, multivariate analysis revealed that age (p =0.008), number of metastatic sites (p <0.001), MNA (p =0.044) and leptin (p =0.004) independently correlated with overall survival. Conclusions: Based on the MNA, the majority of patients were either malnourished or at nutritional risk. MNA correlated with laboratory parameters related to inflammation/cachexia and was independently associated with survival. [Copyright &y& Elsevier]

Objectives In patients with advanced incurable lung cancer deciding as to the most appropriate treatment (e.g. chemotherapy or supportive care only) is challenging. In such patients the TNM classification system has reached its ceiling therefore other factors are used to assess prognosis and as such, guide treatment. Performance status (PS), weight loss and inflammatory biomarkers (Glasgow Prognostic Score (mGPS)) predict survival in advanced lung cancer however these have not been compared. This study compares key prognostic factors in advanced lung cancer. Materials and methods Patients with newly diagnosed advanced lung cancer were recruited and demographics, weight loss, other prognostic factors (mGPS, PS) were collected. Kaplan–Meier and Cox regression methods were used to compare these prognostic factors. Results 390 patients with advanced incurable lung cancer were recruited; 341 were male, median age was 66 years (IQR 59–73) and patients had stage IV non-small cell ( n = 288) (73.8%) or extensive stage small cell lung cancer ( n = 102) (26.2%). The median survival was 7.8 months. On multivariate analysis only performance status (HR 1.74 CI 1.50–2.02) and mGPS (HR 1.67, CI 1.40–2.00) predicted survival ( p < 0.001). Survival at 3 months ranged from 99% (ECOG 0–1) to 74% (ECOG 2) and using mGPS, from 99% (mGPS0) to 71% (mGPS2). In combination, survival ranged from 99% (mGPS 0, ECOG 0–1) to 33% (mGPS2, ECOG 3). Conclusion Performance status and the mGPS are superior prognostic factors in advanced lung cancer. In combination, these improved survival prediction compared with either alone.

Abstract: Anorexia and muscle wasting are frequently observed in cancer patients and influence their clinical outcome. The better understanding of the mechanisms underlying behavioral changes and altered metabolism yielded to the development of specialized nutritional support, which enhances utilization of provided calories and proteins by counteracting some of the metabolic derangements occurring during tumor growth. Inflammation appears to be a key factor determining the cancer-associated biochemical abnormalities eventually leading to anorexia and cachexia. Interestingly, inflammation is also involved in carcinogenesis, cancer progression and metastasis by impairing immune surveillance, among other mechanisms. Therefore, nutritional interventions aiming at modulating inflammation to restore nutritional status may also result in improved response to pharmacological anti-cancer therapies. Recent clinical data show that supplementation with nutrients targeting inflammation and immune system increases response rate and survival in cancer patients. This suggests that nutrition therapy should be considered as an important adjuvant strategy in the multidimensional approach to cancer patients. [Copyright &y& Elsevier]
