Time depended variability in the data of lung cancer by the time, makes it necessary to make informational updates and mortality analysis.In this study, we aimed to make a mortality assessment in cases died from lung cancer in intensive care. Data of patients died from lung cancer in intensive care between January 2013 and January 2015 were retrospectively reviewed. 810 patients have been hospitalized in the intensive care and 420 patients have been hospitalized in the respiratory intensive care. 118 had been diagnosed with primary lung cancer. 56 of the deaths in respiratory intensive care were identified as primary lung cancer and mortality rate of lung cancer cases in intensive care was 47.4% and its proportions in general mortality of intensive care and respiratory intensive care were 21.6% and 45.2% respectively. 11 cases were female and 45 cases were male. The most common cancer types are squamous cell carcinoma (SCC) in general, adenocancer (AC) in females and SCC in males. Smoking rates showed significant differences between genders (45.5% in females and 91.1% in males). Small cell lung cancer (SCLC) has the strongest relation with smoking. While the most common diagnostic procedure was bronchoscopy in general, in SCC and SCLC, transthoracic lung biopsy was the common method in AC. Mean survival times showed significant difference between cancer types and SCLC had the shortest survival time. Mean survival was significantly low in patients with distant organ metastasis. Respiratory failure was the most common indication for intensive care intake. Pneumonia and MODS-sepsis were the most common death causes in all cases. Consequently, lung cancer has a significant proportion in intensive care mortality and the mortality rate of lung cancer is significantly associated to cancer type and metastasis status.
