Outcome of patients with solid malignancies considered for intensive care unit admission: a single-center prospective cohort study.

PURPOSE: To identify the predictors and outcomes of ICU triage decisions in patients with solid malignancies (SM) and to investigate the usefulness of the National Early Warning Score (NEWS) and quick Sequential Organ Failure Assessment (qSOFA) score at triage. METHODS: All patients with SM for whom ICU admission was requested between July 2019 and December 2021 in a French university-affiliated hospital were included prospectively. RESULTS: Of the 6262 patients considered for ICU admission, 410 (6.5%) had SM (age, 66 [58-73] years; metastases, 60.1%; and performance status 0-2, 81%). Of these 410 patients, 176 (42.9%) were admitted to the ICU, including 141 (80.1%) subsequently discharged alive. Breast cancer, hemoptysis, and pneumothorax were associated with ICU admission; whereas older age, performance status 3-4, metastatic disease, and request at night were associated with denial of ICU admission. The NEWS, and the qSOFA score in patients with suspected infection, determined at triage performed poorly for predicting hospital mortality (area under the receiver operating characteristics curve, 0.52 and 0.62, respectively). Performance status 3-4 was independently associated with higher 6-month mortality and first-line anticancer treatment with lower 6-month mortality. Hospital mortality was 33.3% in patients admitted to the ICU after refusal of the first request. CONCLUSION: Patients with SM were frequently denied ICU admission despite excellent in-ICU survival. Poor performance status was associated with ICU admission denial and higher 6-month mortality, but none of the other reasons for denying ICU admission predicted 6-month mortality. Physiological scores had limited usefulness in this setting.

Clinical features and outcomes of patients admitted to the ICU for Cyclophosphamide-associated cardiac toxicity: a retrospective cohort.

PURPOSE: To describe the management and outcome of critically-ill patients with Cyclophosphamide (CY)-associated cardiac toxicity. METHODS: All patients admitted to the intensive care units (ICUs) of the Nantes and Rennes University Hospitals for a CY-associated cardiac toxicity between January 2015 and December 2020 were included. RESULTS: Of the thirty-four patients included in the study, twenty-four (70%) underwent allogeneic hematopoietic stem cell transplantation (HSCT), four (12%) autologous HSCT, and six (18%) chemotherapy for hematological malignancies. Acute pulmonary edema (65%), cardiac arrest (9%), and cardiac arrhythmia (6%) were the most common reasons for ICU admission. Patients were admitted to the ICU 6.5 (4-12) days after the intravenous administration of a median dose of CY of 100 [60-101] mg/Kg. Echocardiographic findings showed moderate to severe left ventricular systolic dysfunction (69%) and pericardial effusion (52%). Eighteen (53%) patients ultimately developed cardiogenic shock and required vasopressors (47%) and/or inotropes (18%). Invasive mechanical ventilation and renal replacement therapy were required in twenty (59%) and five (14%) patients, respectively. Sixteen (47%) patients died of whom 12 (35.3%) died from refractory cardiogenic shock. The left ventricular ejection fraction improved over time in most survivors with a median time until full recovery of 33 (12-62) days. Two (11%) patients had a persistent left ventricular dysfunction at 6 months. CONCLUSION: Refractory cardiogenic shock is the primary cause of death of patients with severe CY-related cardiotoxicity. Nonetheless, the cardiac function of most survivors recovered within a month.
