Mini Nutritional Assessment (MNA) and biochemical markers of cachexia in metastatic lung cancer patients: Interrelations and associations with prognosis

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.

Nutritional status, acute phase response and depression in metastatic lung cancer patients: correlations and association prognosis.

Background and aimCancer cachexia is a metabolic syndrome related with poor outcome. Cytokines play a key role in the pathophysiology of that syndrome. The aim of this study was to investigate the potential correlations between nutritional status, systemic inflammation, and psychological distress in cancer patients. The prognostic significance of the recorded parameters was also assessed.Patients and methodsPatients with metastatic lung cancer were eligible. Mini Nutritional Assessment (MNA) was used for the evaluation of nutritional status, Glasgow Prognostic Score (GPS) for the estimation of systemic inflammation, and Hospital Anxiety and Depression Scale (HADS) for psychological assessment.ResultsTotally, 122 patients were enrolled (71.3% with NSCLC and 28.7% with SCLC). The following correlations were observed: MNA and GPS (r = 0.289, p = 0.001), MNA and HADS (depression scale) (r = 0.275, p = 0.002), GPS and HADS (depression scale) (r = 0.256, p = 0.004), and GPS and HADS (anxiety scale) (r = 0.194, p = 0.033). In univariate analysis, GPS (p = 0.002) and MNA (p = 0.010) emerged as significant predictors of survival. In multivariate analysis, both MNA (p = 0.032) and GPS (p = 0.020) retained their importance.ConclusionsThis study highlights the associations between nutritional status, systemic inflammation, and psychological distress, supporting their common underlying pathophysiological mechanisms and further suggesting the necessity of a holistic anti-cachectic approach.

Baseline Insulin-Like Growth Factor-I Plasma Levels, Systemic Inflammation, Weight Loss and Clinical Outcome in Metastatic Non-Small Cell Lung Cancer Patients

Background: Cancer patients frequently suffer from weight loss and systemic inflammation in the context of advanced disease, which is related to adverse outcome. Insulin-like growth factor (IGF)-I is an anabolic molecule implicated in the maintenance of muscle mass and cancer growth. We investigated potential correlations of IGF-I with an inflammatory and weight loss status and with clinical outcome. Methods: Baseline IGF-I plasma levels were measured in 77 patients (66 males, median age 65.5 ± 10.6 years), diagnosed with metastatic non-small cell lung cancer, and were correlated with serum albumin and C-reactive protein (CRP) levels, weight loss history, treatment response and overall survival. Results: IGF-I correlated with age (p = 0.01), histologic subtype (p = 0.019), albumin (p < 0.001) and CRP (p < 0.001). In univariate analysis, gender (p = 0.005), smoking status (p = 0.012), albumin (p = 0.034) and IGF-I (p = 0.017) were related to time to progression, while IGF-I (p = 0.003), gender (p = 0.049) and smoking status (p = 0.003) retained their significance in multivariate analysis. Age (p = 0.005), gender (p = 0.029), weight loss (p = 0.009), performance status (p < 0.001), number of metastatic sites (p = 0.004), albumin (p = 0.008), CRP (p = 0.022) and IGF-I (p = 0.042) were associated with overall survival, although only gender (p = 0.013), weight loss (p = 0.027), performance status (p = 0.015) and number of metastatic sites (p = 0.021) emerged as independent prognostic factors. Conclusion: IGF-I correlates with systemic inflammation and seems to play an independent predictive role in metastatic non-small cell lung cancer.

The Glasgow Prognostic Score (GPS) predicts toxicity and efficacy in platinum-based treated patients with metastatic lung cancer

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.

Baseline Plasma Levels of Interleukin-8 in Stage IV Non-Small-Cell Lung Cancer Patients: Relationship With Nutritional Status and Prognosis

Interleukin (IL)-8 promotes cellular proliferation and angiogenesis in patients with non-small-cell lung cancer (NSCLC) and may be related to cachexia. Our aim was to investigate the relationship of IL-8 levels with nutritional status, and clinical outcome of patients with NSCLC. Patients with metastatic NSCLC referred for first-line therapy were eligible. Baseline IL-8 levels were measured in plasma. The Mini Nutritional Assessment (MNA) was used for the evaluation of the nutritional status, and patients were classified into 3 groups: A (score 24–30) “well nourished,” B (score 17–23.5) “risk of malnutrition,” and C (0–16.5) “malnourishment.” Response to first-line chemotherapy, time-to-tumor progression (TTP), and overall survival (OS) were also recorded. In total, 114 patients (101 males, 88.5%; mean age = 67.5 yr) were evaluated. Performance status was 0–1 in 62% of the patients. According to the MNA, the majority of patients (71%) was either at nutritional risk or malnourished. IL-8 levels were significantly different between MNA groups (P = 0.023) and correlated with TTP (P = 0.013) and OS (P = 0.001) in univariate analysis. Baseline IL-8 levels correlate with the nutritional status of patients with metastatic NSCLC, suggesting that this cytokine may be related with cachexia.

Non-Platinum-Based First-Line Followed by Platinum-Based Second-Line Chemotherapy or the Reverse Sequence in Patients with Advanced Non-Small Cell Lung Cancer: A Retrospective Analysis by the Lung Cancer Group of the Hellenic Oncology Research Group

Background: Non-platinum-containing regimens have been proposed as alternatives to platinum-based doublets in the first-line treatment of patients with non-small cell lung cancer (NSCLC). However, conflicting results about their equivalence have been reported. Methods: We reviewed the records of patients enrolled in randomized controlled first-line trials conducted by the Hellenic Oncology Research Group from February 1997 to September 2006. The outcome of patients treated with first-line non-platinum-based chemotherapy who received platinum-based chemotherapy upon progression (cohort A) or platinum-based first-line chemotherapy followed by non-platinum-containing second-line chemotherapy (cohort B) was retrospectively analyzed. Results: Two-hundred and sixty-seven patients were identified in cohort A, and 123 in cohort B. Median follow-up time was 12.5 and 15.7 months for cohorts A and B. A significantly higher response rate and time to tumor progression (TTP) was recorded for patients treated with platinum-based compared to those receiving non-platinum-based first-line chemotherapy (45.5 vs. 21.3%, p < 0.0001 and 5.8 vs. 3.1 months, p= 0.002, respectively). Platinum-based regimens administered as second-line treatment resulted in a 13.1% response rate. TTP for second-line chemotherapy did not differ significantly between the two cohorts. Median overall survival was 13.3 and 15.7 months for cohorts A and B (p = 0.538). Conclusion: Both sequences resulted in similar efficacy in terms of overall survival. Encouraging median survival was achieved for selected patients with NSCLC who received both first- and second-line chemotherapy.

A dose escalation study of the biweekly administration of paclitaxel, oxaliplatin and capecitabine in patients with advanced solid tumors

Purpose: To determine the dose-limiting toxicities (DLTs) and the maximum-tolerated doses of the paclitaxel, oxaliplatin (LOHP) and capecitabine combination in patients with advanced solid tumors. Patients and Methods: Patients received escalating doses of paclitaxel (starting dose 100 mg/m2) and LOHP (starting dose 40 mg/m2) on days 1 and 15 and capecitabine (starting dose 800 mg/m2/day) on days 1–7 and 15–21 every 28 days. DLTs were evaluated in the first cycle. Results: Sixteen patients were treated at four dose-escalating levels. Eleven (68.7%) patients had received two or more prior chemotherapy regimens. The DLT level was reached at paclitaxel 110 mg/m2, LOHP 50 mg/m2 and capecitabine 1,000 mg/m2/day. DLTs due to grade 2–3 neutropenia resulted in treatment delays. No febrile neutropenia or treatment-related death occurred. Grade 2–3 neutropenia occurred in 3 (19%) patients each, grade 2–4 fatigue affected 6 (37.5%) patients, and grade 2–3 neurotoxicity was observed in 2 (12.5%) and 1 (6%) patients, respectively. Two partial responses and four disease stabilizations were achieved. Conclusion: The recommended doses for phase II studies are paclitaxel 100 mg/m2 and LOHP 50 mg/m2 on days 1 and 15 and capecitabine 1,000 mg/m2/day on days 1–7 and 15–21 every 4 weeks. This regimen is well tolerated and merits further evaluation.

A Dose Escalation Study of Biweekly Oral Vinorelbine and Gemcitabine in Patients with Solid Tumors

Purpose: To determine the maximum tolerated doses (MTDs) and the dose-limiting toxicities of a biweekly administration of oral vinorelbine and gemcitabine in patients with advanced solid tumors. Patients and Methods: Twenty-eight patients with advanced stage solid tumors were enrolled, and 12 (42.9%) of them were chemotherapy naive. Escalating doses of vinorelbine (50–70 mg/m2 per os) and gemcitabine (800–1,000 mg/m2 as a 30-min intravenous infusion) were administered on days 1 and 15 in 4-week cycles. Results: MTDs were reached at 70 mg/m2 p.o. for vinorelbine and 900 mg/m2 for gemcitabine. Grade 4 neutropenia, febrile neutropenia, grade 4 nausea/vomiting and treatment delay due to grade 3 neutropenia were the dose-limiting events during the first cycle of chemotherapy. A total of 94 chemotherapy cycles were administered with only one episode of febrile neutropenia and no toxic deaths. Severe (grade 3–4) neutropenia occurred in 10% of cycles while non-hematological toxicity was mild with grade 2–3 asthenia occurring in 17 (18%) cycles. Objective responses were achieved in patients with prostate and non-small cell lung cancer. Conclusions: The combination of biweekly oral vinorelbine (70 mg/m2) and gemcitabine (900 mg/m2) is a well-tolerated regimen with promising results in patients with advanced solid tumors.
