Leucopenia is an independent predictor in cancer patients requiring invasive mechanical ventilation: a prognostic factor analysis in a series of 168 patients.
OBJECTIVE
To determine prognostic factors predicting success of invasive mechanical ventilation in medical cancer patients admitted to ICU for a complication, in terms of extubation and ICU and hospital discharges.


METHODS
Retrospective study


METHODS
Medical ICU of an European cancer hospital.


METHODS
A total of 168 consecutive cancer patients who were admitted to ICU for an acute medical complication requiring immediate mechanical ventilation or who later needed mechanical ventilation.


METHODS
Variables related to the demographic, cancer, scores and complication characteristics. Extubation rates, ICU and hospital mortalities and duration of survival were measured.


RESULTS
Respectively, 26%, 22% and 17% of the patients were extubated, discharged from the ICU and discharged from hospital. For weaning from mechanical ventilation, a higher APACHE II score and leucopenia were poor prognostic factors in univariate analysis, but leucopenia remained the only significant one in multivariate analysis. For ICU mortality, no significant prognostic feature was identified. For hospital mortality, leucopenia was the only significant factor in univariate as well as in multivariate analyses.


CONCLUSIONS
Leucopenia appeared to be the only independent poor prognostic factor for both extubation and hospital discharge. None of the variables related to the cancer disease process was shown to be a predictor of success.
