RESUMO

PURPOSE: Elevated fibrinogen (Fbg) levels contribute to tumor progression and metastasis. However, little is known regarding the association of the clinicopathological characteristics and the prognosis of hilar cholangiocarcinoma (HC) with plasma fibrinogen. METHODS: Data on the plasma Fbg levels, clinicopathological characteristics, and overall survival were retrospectively collected. Plasma fibrinogen concentrations over 4.0 g/L were classified as hyperfibrinogen, elevated fibrinogen, or abnormal fibrinogen levels. We then analyzed the relationships among plasma fibrinogen level, clinicopathological features, and patient prognosis. RESULTS: A total of 171 HC patients were included. An elevated plasma fibrinogen level was associated with lymph-node metastasis (P < 0.001), the AJCC stage (P < 0.001), the surgical margin (P = 0.005), and vascular invasion (P = 0.027). Univariate analyses revealed that preoperative plasma fibrinogen (P < 0.001), operative blood loss (P = 0.044), vascular invasion (P < 0.001), CA19-9 (P = 0.003), surgical margin (P < 0.001), T stage (P < 0.001), histologic differentiation (P = 0.007), and lymph-node metastasis (P < 0.001) were associated with OS. The survival time of patients with high Fbg levels was shorter than that of patients with normal fibrinogen levels (P < 0.001). Furthermore, a multivariate analysis showed that fibrinogen was negatively and independently associated with the HC prognosis (P = 0.029). CONCLUSIONS: An elevated plasma Fbg level was associated with lymph-node metastasis, vascular invasion, the surgical margin, and the tumor stage, and the Fbg level might therefore be an independent factor associated with poor outcomes in HC patients.

RESUMO

BACKGROUND: Early recurrence has been reported to be predictive of a poor prognosis for patients with perihilar cholangiocarcinoma (pCCA) after resection. The objective of our study was to construct a useful scoring system to predict early recurrence for Bismuth-Corlette type IV pCCA patients in clinic and to investigate the value of early recurrence in directing post-operative surveillance and adjuvant therapy. METHODS: In total, 244 patients who underwent radical resection for type IV pCCA were included. Data on clinicopathological characteristics, perioperative details and survival outcomes were analyzed. Survival curves were generated using the Kaplan-Meier method. Univariate and multivariate logistic-regression models were used to identify factors associated with early recurrence. RESULTS: Twenty-one months was defined as the cutoff point to distinguish between early and late recurrence. Univariate and multivariate analysis revealed that CA19-9 level >200 U/mL, R1 resection margin, higher N category and positive lymphovascular invasion were independent predictors of early recurrence. The scoring system was constructed accordingly. The early-recurrence rates of patients with scores of 0, 1, 2, 3, 4, and 5 were 23.9%, 38.7%, 60.0%, 78.6%, 83.4%, and 100%, respectively. Adjuvant therapy was significantly associated with higher overall survival rate for patients with early recurrence, but not for those with late recurrence. Patients in the early-recurrence group with scores ≥2 had better prognoses after adjuvant therapy. CONCLUSIONS: A simple scoring system using CA19-9 level, N category, resection margin and lymphovascular invasion status could predict early recurrence, and thus might direct post-operative surveillance and adjuvant therapy for patients with type IV pCCA.
