Cox proportional hazards regression, followed by bootstrap validation, was used to identify independent prognostic factors for OS.\n\nResults: The median OS for the whole cohort was 22 months (95% CI, 20.2 to 26.5 months), and the median follow-up was 24.5 months. Overall, 396, 200, and 49 patients were treated with sunitinib, sorafenib, and bevacizumab, respectively. Four of the five adverse prognostic factors according to the Memorial Sloan-Kettering Cancer Center (MSKCC) were independent predictors of short survival: hemoglobin less than the lower limit of normal (P <.0001), corrected calcium greater than the upper limit of normal (ULN; P =.0006), Karnofsky performance status less than 80% (P <.0001), and time from diagnosis to treatment of less than 1 year (P =.01). In addition, neutrophils greater than the ULN (P <.0001) and platelets greater than the ULN (P =.01) were independent adverse prognostic factors. Patients were segregated into three risk categories: the favorable-risk group (no prognostic factors; n = 133), in which median OS (mOS) was not reached and 2-year OS (2y OS) was 75%; the intermediate-risk group (one or two prognostic factors; n = 301), in which mOS was 27 months and 2y OS was 53%; and the poor-risk group (three to six prognostic factors; n = 152), in which mOS was 8.8 months and 2y OS was 7% (log-rank P <.0001). The C-index was 0.73.\n\nConclusion: This model validates components of the MSKCC model with the addition of platelet and neutrophil counts and can be incorporated into patient care and into clinical trials that use VEGF-targeted agents.\n\nIndexed on Europe PMC as PubMed record 19826129 (DOI 10.1200/jco.2008.21.4809).
