Long-term Outcomes of Cancer Patients Admitted to the ICU with Septic Shock.

Introduction: Several studies evaluated the outcomes of cancer patients treated with septic shock in intensive care units (ICUs), but limited data is available on the long-term outcomes of this patient population. In this report, we aimed to evaluate the one-year mortality in cancer patients who were discharged alive following their intensive care unit (ICU) admission for septic shock.

Patients and methods: A retrospective study that was conducted at an oncologic ICU of a comprehensive cancer center. The study included all adult cancer patients who were admitted to the ICU with septic shock between 2008 and 2019. Septic shock was defined as the need to start vasopressors within the first 24 hours of ICU admission with sepsis. Patient baseline characteristics and longterm outcomes were evaluated. Descriptive analysis was used to report the data.

Results: Of the 1408 cancer patients who were admitted to the ICU with septic shock, 494 patients (35%) were discharged alive from the hospital. Their mean age was 56.3±16.5 (SD) years, 321 (65%) were males, and 326 (66%) had solid tumors. At 1-year, 258 patients died as follows: 129 (50%) died during the first 3-months, 69 (27%) patients died between 3 and 6-months, and 60 (23%) patients died between 6 and 12-months, resulting in a mortality rate of 74%, 78.9% and 83.2%, at the 3-months, 6-months and 1-year, respectively.

Discussion and conclusion: In this cohort of cancer patients, we described the long-term outcomes of patients treated in the ICU with septic shock. The majority of the included patients died during the first year following their ICU admission. Future studies should identify measures to improve the outcomes of this patient population.
