Abstract: Objective To identify influencing factors of hope level in patients with lung cancer, so as to find and identify patients with lower hope level as early as possible, and to provide reference for the formulation of intervention measures to improve hope level in patients with lung cancer. Methods Total of 266 patients with lung cancer who were treated in Peking Union Medical College Hospital from July 2024 to December 2024 were selected as the research objects. Herth Hope Index (HHI) was used to investigate the hope level of the included patients.The hope level of lung cancer patients with different characteristics was compared, and the decision tree(DT) and Logistic regression model were used to analyze the influencing factors of the hope level of lung cancer patients. Results After excluding 9 patients who answered invalid questionnaires, 257 patients were included in this study. Logistic regression model showed that the days since diagnosis (B=-0.001), lung cancer classification[adenocarcinoma(B=0.177), squamous cell carcinoma (B=1.949), others (B=1.458)], education level [high school, vocational school or technical school (B=-1.182), junior college (B=0.392), bachelor′s degree or above (B=1.040)], immunotherapy(B=-0.682), the score of Eastern Cooperative Oncology Group (ECOG) performance status (PS) [grade 1 (B=1.657), grade 2 (B=2.102) , grade 3 (B=0.171)]and the score of Connor-Davidson Resilience Scale (CD-RISC) (B=-0.060) were independent factors influencing the occurrence of the medium hope level in lung cancer patients.The results of decision tree showed that the total score of CD-RISC was the main factor affecting the hope level of lung cancer patients, followed by education level and the days of diagnosis. The area under the curve(AUC) of the two models was 0.853(0.806,0.900) and 0.850 (0.801, 0.898) respectively with no statistically significant difference (Z=0.144, P=0.885). Conclusions Both Logistic regression model and decision tree have certain application value in predicting the hope level of lung cancer patients. It is suggested to combine the two models in clinical practice in order to improve the hope level of lung cancer patients.
