The objective of this study was to identify targets for interventions to reduce end-of-life care disparities among patients with advanced cancer. To do this, the authors evaluated the degree to which end-of-life care values and preferences are associated with advance care planning within racial/ethnic minority groups. ⋯ Preferences against life-prolonging care differ dramatically by race/ethnicity, but they have a uniform significant association with DNR order completion rates across racial/ethnic groups of patients with advanced cancer. Advance care planning interventions that target preferences associated with DNR orders across racial/ethnic groups may reach a broad patient population and reduce end-of-life care disparities.

Circulating proteins released by tumor cells have recently been investigated as potential single surrogate biomarkers for glioblastoma multiforme (GBM). The aim of the current hypothesis-generating study was to evaluate the diagnostic and prognostic role of preoperative insulin-like growth factor-binding protein 2 (IGFBP-2), chitinase-3-like protein 1 (YKL-40), and glial fibrillary acidic protein (GFAP) plasma levels in patients with GBM, both as single markers and as a combined profile. ⋯ A combined profile of preoperative IGFBP-2, GFAP, and YKL-40 plasma levels could serve as an additional diagnostic tool for patients with inoperable brain lesions suggestive of GBM. In addition, IGFBP-2 levels appear to constitute an independent prognostic factor in patients with GBM.

The validity of the KRAS mutation as a predictor of recurrence-free survival (RFS) or overall survival (OS) is unclear. The current study investigated whether the presence of the KRAS mutation decreased RFS or OS in patients with colorectal cancer who underwent liver resection. ⋯ In the current study, among patients with resected colorectal liver metastases who were treated with adjuvant hepatic arterial infusion plus systemic therapy, patients with KRAS MUT were found to have a significantly worse 3-year RFS (30%) compared with KRAS WT (46%) p=.005. The cumulative incidence of bone, brain, and lung metastases was significantly higher for patients with KRAS MUT compared with those with KRAS WT.
