[Objective] To understand the risk factors for nosocomial infectious diseases in patients with malignant tumors. [Methods] Retrospective analysis of hospital lower respiratory tract infections in 72 patients with malignant tumors. [Results] The average length of stay in patients with malignant tumors was prolonged and the chance of lower respiratory tract infection was greatest.
