Energy and protein intake and nutritional status in non-surgically treated patients with small cell anaplastic carcinoma of the lung.

The spontaneous food intake and nutritional status was assessed in 23 patients with small cell anaplastic carcinoma of the lung before and two times during a treatment period of 6 weeks. Radiation therapy was given for 2 weeks followed by a course of chemotherapy and another 2 weeks of radiation therapy. The energy intake decreased during the treatment from 146 to 130 per cent of basal metabolic rate (p greater than 0.10). The protein intake remained unchanged (mean 0.9 g/kg body weight). There were insignificant and small losses of weight, body fat, free body mass and arm muscle circumference, and no changes were seen in serum albumin and serum transferrin. However, 6 patients suffered a weight loss of 5 per cent or more. No correlation existed between the nutritional parameters measured before treatment and the changes during treatment. Patients who suffered a loss of body weight could therefore not be singled out before the treatment.
