| Popis: | It has been previously indicated that preoperative plasma fibrinogen levels can correlate with cancer progression and be used as a useful predictor of lymph node metastasis or its premetastatic status such as lymphovascular invasion (LVI). In the present study, how preoperative plasma fibrinogen levels, considered in conjunction with other clinicopathological factors, can predict the presence of LVI and prognosisin patients with upper urinary tract urothelial carcinoma (UTUC) was examined. Medical records of 145 patients with UTUC who underwent radical nephroureterectomy (RNU) were retrospectively reviewed. The current study evaluated systemic inflammatory response markers including levels of plasma fibrinogen and other clinicopathological factors in orderto determine independent predictors of LVI and prognosis. The Cox proportional hazards model indicated that positive surgical margins and LVI were independent factors for poor cancer-specific survival (CSS) rates and extraurothelial recurrence-free survival (ERFS) rates. In addition, positive cytology, the presence of hydronephrosis and plasma fibrinogen levels were significant preoperative predictors of LVI. Furthermore, patients exhibiting two or more of higher fibrinogen levels (≥400 mg/dl), positive urine cytology and the presence of hydronephrosis were indicated to exhibit worse CSS or ERFS rates compared with patients exhibiting only one of the aforementioned factors or those with none of the three aforementioned factors in the multivariate analysis of the Cox proportional hazards model. In conclusion, hyperfibrinogenemia can be an independent predictor of the presence of LVI, and stratifying preoperative risk using fibrinogen levels, urine cytology and hydronephrosis can serve as the basis for selecting candidates for additional therapy before and/or after RNU in patients with UTUC. |
