BackgroundMore lung cancer cases are becoming diagnosed earlier in recent years. The diagnosis is often accompanied by fear of progression (FoP). There is a clear research gap in the existing literature on FoP and the most frequent concerns in newly diagnosed lung cancer patients.ObjectiveTo identify the status and factors related to FoP in newly diagnosed Chinese lung cancer patients undergoing thoracoscopic lung cancer resection.MethodsA cross-sectional design with convenience sampling was used in this study. Participants (N = 188) with newly diagnosed lung cancer (≤ 6 months) at one hospital in Zhengzhou were recruited. A demographic questionnaire, Fear of Progression Questionnaire-Short Form, Social Support Rating Scale (SSRS), Simplified Coping Style Questionnaire, and Brief Illness Perception Questionnaire were used to assess characteristics, FoP, social support, coping style, and patient illness perceptions. Multivariable logistic regression analysis was used to identify factors associated with FoP.ResultsThe mean score of FoP was 35.39 ± 8.03. There are 56.4% of the patients (scores ≥ 34) have a clinically dysfunctional level of FoP. FoP was higher in young (18–39 years) than middle-aged patients (40–59 years) and elderly patients (≧60 years) (P= 0.004). Patients aged 40–59 years showed significantly higher fear of family-related concerns (P< 0.001), a fear of potential harm from medications (P= 0.001); Patients aged 18–39 years and 40–59 years showed significantly higher fears of work-related concerns (P= 0.012). Multiple logistic regression analyses showed that patients’ age, the time from surgery and SSRS score were found to be independently associated with higher FoP.ConclusionsHigh FoP is a frequently reported problem among newly diagnosed lung cancer patients, especially those less than 60 years old. Professional psychoeducation, psychological interventions, and personalized support are needed for patients with a high FoP.
