Prevalence and correlation of anxiety and depression on the prognosis of postoperative non-small-cell lung cancer patients in North China

Identify the prevalence of postoperative anxiety and depression as well as their correlations with clinical features and survival profiles in non-small-cell lung cancer (NSCLC) patients who underwent resection. Four hundred NSCLC patients who underwent resection were recruited, and their anxiety and depression were assessed by hospital anxiety and depression scale (HADS) at discharge after surgery. Besides, 480 healthy controls (HCs) were also enrolled and assessed by HADS. The HADS-Anxiety score of NSCLC patients (7.8 ± 3.9) was greatly higher than that of HCs (4.8 ± 2.7), and the anxiety prevalence of NSCLC patients (49.6%) were dramatically increased compared with HCs (13.8%). Furthermore, the HADS-Depression score (7.2 ± 3.6) of NSCLC patients was considerably increased compared with HCs (4.2 ± 2.6), and the depression prevalence of NSCLC patients (38.3%) was significantly raised compared with HCs (10.0%). Besides, anxiety correlated with gender, marital status, hypertension, diabetes, pathological differentiation, tumor size, lymph node metastasis, TNM stage and carcinoembryonic antigen level, meanwhile, depression correlated with marital status, employment status before surgery, diabetes, pathological differentiation, and TNM stage in NSCLC patients. Additionally, the anxiety and depression predicted shorter disease-free survival in NSCLC patients. And the anxiety predicted worse overall survival (OS), while no association of depression with OS was observed in NSCLC patients. Post-operative anxiety and depression are highly prevalent and implicated in the ongoing care and prognosis prediction in NSCLC patients who underwent resection.
