Abstract

Introduction: The role of preoperative serum-based markers in predicting survival outcomes of patients has been reported for several cancer types; however, their association with upper tract urothelial carcinoma (UTUC) prognosis is unclear. We evaluated the role of systemic serum-based markers in predicting adverse pathological features and survival outcomes in patients surgically treated for high-grade (HG) UTUC. Methods: We retrospectively reviewed all patients undergoing surgery for HG UTUC between June 2006 and July 2013 at our institution. Comprehensive clinicopathologic data and preoperative serum-based markers including hemoglobin, white blood cell count, platelet count, serum albumin, calcium, and liver function tests were recorded. Associations of serum markers with pathologic features and recurrence-free survival (RFS) were determined by logistic and Cox regression analyses, respectively. The concordance index for the oncologic outcomes model was determined. Results: In total, 101 patients were identified with a median follow-up of 18.5 months (range: 1-74. mo). In all, 60% of patients had pT2 or less and 11% had nodal metastases. Preoperative elevated alkaline phosphatase (ALP) (≥116. IU/l) was associated with multiple adverse pathologic features including advanced T stage, lymphovascular invasion, and histologic necrosis. On univariate analysis, serum markers independently associated with RFS included hemoglobin≤12.9 (hazards ratio [HR] = 2.51; 95% CI: 1.17-5.36, P = 0.018), albumin≤4. g/dl (HR = 4.4; 95% CI: 2.04-9.30; P
