Impact of hospitalization on the nutritional status of cancer patients.

Abstract

This study was undertaken to examine the influence of hospitalization on the nutritional status of cancer patients. We examined 126 patients consecutively admitted to the Istituto Nazionale Tumori of Milan. At admission, all patients underwent standard evaluations, including actual weight, percentage weight loss, arm circumference, triceps skinfold, serum proteins, serum albumin, total iron binding capacity, cholinesterase and peripheral lymphocytes. Finally, from all patients a 24-h dietary recall was obtained, in order to calculate calorie and protein intake. All the patients underwent another evaluation after 1 week of hospitalization; after 2 weeks only 37 of them were evaluated again, since some were operated, some were treated with radio-chemotherapy, some were discharged or had died. Results showed that after one week of hospitalization some variables were significantly altered, such as arm circumference in male patients, serum proteins, cholinesterase, total iron binding capacity, peripheral lymphocytes, calorie and protein intake. A significant weight loss was seen after 2 weeks. The reduced calorie and protein assumption was correlated with depletion of some of the nutritional variables (body weight, arm circumference in males, total iron binding capacity, serum albumin, cholinesterase, lymphocytes). Our data show that hospitalization plays an important role in deterioration of nutritional status in our patient population, and this problem is generally overlooked by the clinicians primarily involved in the care of cancer patients.
