Critically ill patients with cancer are vulnerable to infections because of the underlying malignancy, tumor-directed therapy, immunosuppression, breaches in mucosa or skin, malnutrition, and other factors. Neutropenia remains the most important risk factor for infection. Infectious complications occurring in critically ill patients with cancer can affect the bloodstream, lungs, gastrointestinal tract, central nervous system, urinary tract, and the skin. Pneumonias are the leading cause of infection in patients with cancer admitted to the intensive care unit. Consideration of opportunistic pathogens in the differential diagnosis is important in patients with impaired cellular and/or humoral immunity or compromised splenic function.
癌症重症患者由于基础恶性肿瘤、肿瘤靶向治疗、免疫抑制、黏膜或皮肤破损、营养不良和其他因素而易发生感染。中性粒细胞减少仍然是感染的最重要危险因素。癌症重症患者发生的感染性并发症可影响血液、肺部、胃肠道、中枢神经系统、尿路和皮肤。肺炎是入住重症监护病房的癌症患者感染的主要原因。对于细胞和/或体液免疫受损或脾脏功能受损的患者,在鉴别诊断中考虑机会性病原体很重要。
