Nutritional status is associated with the progression of malignant neoplasms. The present study aimed to assess the nutritional status of cancer patients using a combination of objective and subjective assessment methods.

Sociodemographic data and blood samples were collected from 152 cancer patients from ATTIKON University Hospital. The time frame was April - October 2019. Validated questionnaires were used to assess their nutritional status (PG-SGA, NRS-2002, SNAQ). In addition, geriatric nutritional risk index (GNRI) was calculated, handgrip strength test was carried out and arm circumference and skin fold thickness were measured.

The study sample consisted of 50.7% women, the median age was 61.0 (IQR: 14) years and median Body Mass Index 24.4 (IQR: 5.95) kg/ m2. Based on the PG-SGA assessment, 54.9% of our sample was severely malnourished while 19.7% had moderate or suspected malnutrition. Imminent danger observed in the 83.6% (NRS-2002) and 48.7% of participants were at increased risk of a 5% reduction in body weight within the next 6 months (SNAQ). Compared to other cancer types, patients with GI track and colorectal cancer had higher values of PG-SGA scores. The median for albumin levels was within normal limits (4.10 (IQR: 0.6) g/dl). According to GNRI, high risk for malnutrition was indicated for geriatric patients (GNRI: 46.45 (IQR: 5.17)). Malnourishment, based on PG-SGA, was positively associated with %weight loss within the past six months and negatively associated with BMI, hemoglobin, handgrip strength and arm circumference (all p<0.05).

The present study showed that a significant proportion of cancer patients were malnourished. Furthermore, poor nutritional status was positively associated with weight loss and negatively associated with body mass index, hemoglobin, handgrip strength and arm circumference.
