Background: Cancer is the second cause of disease-related deaths worldwide. Malnutrition among cancer patients is very common, with an estimated incidence of approximately 40 to 80%. While it is already a proven fact that malnutrition is prevalent among cancer patients, its impact on the quality of life of patients has not been adequately studied, particularly in the local setting. Purpose: To assess quality of life, nutrition status and to determine the affects of nutrition status on quality of life of cancer patients treated chemotherapy at Oncology Department, Hue University of Medicine and Pharmacy Hospital. Methods: A cross sectional study with 70 cancer patients admitted for chemotherapy recruited from at oncology department, Hue University of Medicine and Pharmacy Hospital during March to September 2018. The EORTC QLQ-C30 were used to assess quality of life and Subjective Global Assessment scale were used to assess nutrition status. T-test, ANOVA, Mann Whitney, Kruskal Wallis were used to determine the correlation between 2 factors. Pearson and Spearman Coefficient were used to measure the strength of relationship between the factors. Results: Patient’s mean age was 58.93 ± 13.26, males were 61.3%. There were 67.14% patients with SGA A, 14.29% were classified SGA-B (moderately malnourished) and 18.57% were classified SGA C (severely malnourished). The global health scale, the functional scales were in the limit of the EORTC reference value, meanwhile the toxicities -related symptom scales were worse than the EORTC reference value. Patients were statistically different across the Subjective Global Assessment groups according to emotional (p < 0.05), and cognitive functioning (p < 0.05) nausea and vomiting (p < 0.05). Conclusions: This study showed that there were the effects of nutrition status on quality of life in patients treated chemotherapy. Key words: Quality of life, nutritional status, cancer, chemotherapy
