Outcome Analyses After the First Admission to an Intensive Care Unit in Patients With Advanced Cancer Referred to a Phase I Clinical Trials Program

Abstract

This study assessed outcomes of individuals with advanced cancer who required admission to an intensive care unit (ICU) after referral for an early clinical trial because they did not respond to conventional therapy. Outcome analyses were conducted for 212 consecutive patients admitted to The University of Texas MD Anderson Cancer Center ICU after being seen in the phase I clinic starting on May 1, 2007. All data were obtained by a review of electronic medical records of patients. The median survival of 212 patients with advanced cancer referred to phase I care after the initial ICU admission was 3.2 weeks (95% CI, 2.5 to 4.9 weeks). Patients who underwent cardiopulmonary resuscitation (CPR) succumbed within a median survival of 1 day (75% and 25% estimated survival of 1 and 3 days, respectively). Patients admitted for a postsurgical intervention did better than patients admitted for a nonsurgical intervention (median survival, 21.5 versus 2.1 weeks; P < .0001). The multivariate analysis revealed that a nonsurgical intervention, hypoalbuminemia, and higher Acute Physiology and Chronic Health Evaluation II scores were associated with poor overall survival. The outcome of patients in a phase I clinic after initial ICU admission was poor, particularly when admission was for a nonsurgical intervention and/or when CPR was needed.
