Effect of nutritional status on psychological functioning and coping in patients with lung cancer

Objectives: Lung cancer is the most common cancer. In patients with lung cancer, malnutrition may result in shorter overall survival, poorer treatment response, increased risk for complications and impaired physical and mental function. The aim of this study was to assess the effects of nutritional status on the psychological functioning and coping in patients with lung cancer. Methods: The present study included 310 patients treated for lung cancer at the Lung Center between 2019 and 2020. The standardized instruments were used: Mini Nutritional Assessment (MNA) and Mental Adjust-ment to Cancer (MAC). Of the 310 patients, 113 (59%) were at risk for malnutrition and 58 (30%) had malnutrition. Results: Patients with a satisfactory nutritional status and those at risk for malnutrition reported statistically significantly higher levels of constructive coping compared with patients with malnutrition (P = 0.040). Patients with malnutrition were more likely to have more advanced cancer: T4 tumor (60.3 versus 38.5; P = 0.007), distant metastases: M1 or M2 (43.9 versus 28.1; P = 0.043), tumor metastases (60.3 versus 39.3; P = 0.008) and brain metastases (19 versus 5.2: P = 0.005). Patients with malnutrition were more likely to have higher levels of dyspnea (75.9 versus 57.8; P = 0.022) and a performance status of & GE;2 (69 versus 44.4; P = 0.003). Conclusions: Malnutrition is significantly more common in patients using negative strategies for coping with cancer. Lack of constructive coping is a statistically significant predictor of increased risk for malnutrition. Advanced cancer stage is a statistically significant independent predictor of malnutrition, increasing the risk of malnutrition by more than twofold.& COPY; 2023 Elsevier Inc. All rights reserved.

Automated summary

This study aimed to assess the effects of nutritional status on the psychological functioning and coping in patients with lung cancer. The results showed that patients with malnutrition had poorer coping ability compared to those with satisfactory nutritional status. Patients with malnutrition were more likely to have advanced cancer and dyspnea. The study indicates a close relationship between nutritional status and psychological functioning and coping in patients with lung cancer.
