Assessment of nutritional status in cancer patients: widely neglected?

There is evidence that malnutrition is an important cause of morbidity and mortality in lung cancer patients and may have an impact on the clinical course of disease. The simplest way to assess nutritional status at the patient's bedside remains recourse to anthropometric measurements. This study was carried out in order to assess the clinical and prognostic significance of triceps skinfold thickness (TST), arm circumference (AC), and wrist circumference (WC) in lung cancer. The patient population was a consecutive series of 388 patients seen for a newly diagnosed primary non-small-cell lung cancer during the last 4 years. A set of 22 anthropometric, clinical, physical, laboratory, radiological, and pathological variables was prospectively recorded for all patients. Patients were carefully followed up, and their subsequent clinical course was recorded. The median values of TST, WC and AC were 8 mm (range 2-25 mm), 18 cm (range 10-27 cm), and 25 cm (range 15-35 cm), respectively. In 107 patients (27.6% of the total) TST values were below the reference value, and 37 of these patients also had a pathologically low small circumference. In all, AC was below the normality range in 60 of the 388 subjects (15.5%). Among the three variables, the strongest relationships were those between AC and WC (r(s)=0.541), and between TST and AC (r(s)=0.521). Univariate analyses of survival showed that TST was strongly predictive of a better prognosis (P<0.001), while WC was unrelated to outcome (P=0.101). Patients with higher values of AC had significantly longer survival than patients with lower values (P<0.018). The multivariate model, in contrast, did not confirm the prognostic capability of any of the anthropometric measures. These data indicate that the anthropometric measures may be significant predictors of survival, although not independently of the other prognostic factors.

Consecutive cancer referrals to a palliative medicine program were evaluated to assess nutritional status using a standard protocol. The study included 352 patients (180 men, 172 women; median age 61 years, range 22-94 years). The most common diagnosis was lung cancer. All had metastatic disease, 139 with gastrointestinal involvement. The most common gastrointestinal symptoms were weight loss ( n=307), anorexia ( n=285), and early satiety ( n=243). Of those with any weight loss, 71% had lost >or0% of their pre-illness weight. The most common factor identified which might have contributed to weight loss was hypophagia ( n=275/307). Men had lost weight more often and to a greater extent than women. Triceps skinfold (TSF) was measured in 337: 51% had values that suggested severe fat deficiency. Upper mid-arm muscle area (AMA) was measured in 349: 30% had evidence of significant muscle mass reduction. The body mass index (BMI) was normal or increased in most patients. Calculated resting energy expenditure (REE) ( n=324) was high in 41%. C-reactive protein was elevated in 74% of those measured ( n=50). We conclude that: (1).most of this group of cancer patients referred to palliative medicine had severe weight loss; (2).there was a gender difference in the severity and type of weight loss; (3).males lost more weight overall and more muscle than females; (4).males with any degree of weight loss had a higher REE than females; (5).a significant correlation existed between the time from diagnosis to death and the severity of weight loss in the prior month; (6).BMI was normal in most patients, suggesting precancer diagnosis obesity; and (7).both TSF and AMA correlated well with body composition of both fat and protein as determined by bioelectrical impedance.

“…11,12 There are various methods of assessing nutritional status in cancer, the most commonly used tools are subjective global assessment (SGA), bioelectrical impedance analysis (BIA), and laboratory measurements of serum albumin, pre-albumin and transferrin. [13][14][15][16][17][18] Others include anthropometric parameters such as weight loss, arm muscle circumference and skin-fold thickness. [19][20][21] Serum albumin is generally used to assess the nutritional status, severity of disease, disease progression and prognosis.…”
