AIM: Dyspnoea is a frequent and compromising symptom in patients with advanced and metastatic lung cancer. Exogenous as well as endogenous factors contribute to development of shortness of breath. Knowledge of these influences is essential for effective treatment of this important symptom. In our study, we evaluated the influence of cofactors and comorbidity on development of dyspnoea in lung cancer patients for the purpose of effective therapy of shortness of breath in this target group.
METHODS: In this prospective monocentric study, we registered severity of dyspnoea in advanced lung cancer patients using the modified Medical Research Council-Scale (mMRC-scale). Patients' history of COPD and cardiopulmonary comorbidity was recorded using a standardized questionnaire. Moreover, cofactors such as pain or cancer-induced mental stress were documented by visual rating scale.
RESULTS: 25 (48,1 %) of 52 recruited lung cancer-patients reported moderate or severe dyspnoea. In logistic regression analysis history of COPD or cardiopulmonary comorbidity, severe pain, airway obstruction or pleural effusion were associated with severe dyspnoea (mMRC-scale ≥ 3). Furthermore, in our study cohort lower cancer level III UICC and absence of metastasis correlated with severe dyspnoea.
CONCLUSIONS: Our findings confirm the relevance of dyspnoea in patients with advanced lung cancer. Probability of occurrence is influenced by comorbidity and cofactors. The knowledge of these factors contributes to better understanding of occurrence and treatment of dyspnoea.
