Purpose: The aim of this study was to evaluate the nutritional status of patients receiving definitive or adjuvant radiotherapy with
head and neck, pelvic, thoracic and intraabdominal tumors and to determine their weight loss.
Methods: 40 patients admitted to the radiation oncology outpatient clinic since 01.11.2015 and planned; head, thoracic,
abdominal and pelvic radiotherapy, were included in the study. The patients were evaluated before the treatment and in addition
to the daily nutrition of the patients, special nutritional support was provided as 35 kcal/kg energy, 2gr/kg protein and 15 mg
glutamine daily. The weight loss of the patients evaluated by radiation oncologists and nurses was recorded.
Results: The mean age was 61 years (range, 39-86 years). 9 patients with lung cancer were over 70 years old and had definitive
radiotherapy. All patients underwent radiotherapy treatment without interrupting treatment, except for an 86-year-old patient
scheduled for adjuvant therapy with gastric cancer and two patients with lung cancer receiving chemoradiotherapy. 72% of the
patients continued their nutritional support during the entire treatment. When weight loss was evaluated, only 8% of patients
had more than 10% weight loss. According to nutritional support, weight loss rates were found to be significantly lower in
patients who fully applied for nutritional support (p: 0.003).
Conclusion: Early and intense nutritional support of cancer patients with risk of malnutrition may lead to less weight loss during
