Physician-reported performance status (PS) constitutes the established method for stratifying oncologic patients in therapeutic decision-making. Objective measurements of physical function may further refine prognostication. In this prospective observational study, 103 patients with metastatic cancer who were referred for systemic therapy initiation were evaluated. PS was evaluated using the Eastern Cooperative Oncology Group Performance Status (ECOG-PS) and five objective physical function measurements (handgrip strength [HGS], chair stand test [CST], timed up and go [TUG] test, 4-m gait speed [GS] test, and short physical performance battery [SPPB] test). Overall survival and treatment complications were recorded from the medical records. Patients with low PS according to ECOG-PS (hazard ratio [HR]: 3.80, 95% confidence interval [CI]: 1.84, 7.80), HGS (HR: 2.37, 95% CI: 1.24, 4.55), SPPB (HR: 3.43, 95% CI: 1.55, 7.57), GS (HR: 3.03, 95% CI: 1.44, 6.38), and TUG (HR: 5.16, 95% CI: 2.19, 12.14) had shorter overall survival after adjustment for sex, age, symptomatology, comorbidity, percentage of weight loss, and tumor localization. Among the studied objective physical function measurements, HGS, SPPB, GS, and TUG were independent predictors of survival in a sample of patients with metastatic cancer, with TUG showing the highest effect size.

Advanced cancer often results in reduced dietary intake; however, data on actual intake at the time of diagnosis are limited. In the present study, a detailed dietary intake assessment was performed in patients with metastatic lung and upper gastrointestinal cancer, before initiation of systemic therapy. Basic demographics and performance status (PS) were recorded. Nutritional status was evaluated through anthropometry, Mini Nutritional Assessment (MNA), and 3 nonconsecutive 24-hour dietary recalls. Of the 84 patients enrolled, 61.4% were protein, energy, or protein–energy undernourished, regardless of body mass index (BMI) or MNA category. No differences in energy, macronutrients, and micronutrients intakes across BMI categories were recorded. Very low consumption of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), irrespective of energy intake, tumor site, BMI category, or PS was found. Suboptimal micronutrients intakes were recorded even in well-nourished and overweight/obese patients. Patients with adequate PS and better MNA score reported significantly higher intake of certain macro- and micronutrients (allP< 0.05). Most patients exhibited reduced dietary intake in terms of energy, macronutrient, and micronutrient. Very low EPA and DHA intake was recorded for the whole sample, whereas micronutrient suboptimal intakes were also prevalent in well-nourished or overweight patients. All the above should be taken into account during patients' nutritional care. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM PUBLISHER]
