Prognostic Impact of Preoperative Thrombocytosis on Recurrence-Free Survival in Patients with Upper Tract Urothelial Carcinoma.

BACKGROUND: The aim of this work was to evaluate the prognostic potential of preoperative thrombocytosis for recurrence-free survival (RFS) and cancer-specific survival (CSS) among patients subjected to radical nephroureterectomy (RNU) due to UTUC. PATIENTS AND METHODS: Analytical cohort was composed of a single-center series of 405 patients treated between January 1999 and December 2020. Thrombocytosis was defined as a platelet count exceeding the threshold value of 400 × 109 per L. Along with the Kaplan-Meier survival probability, Cox proportional hazard regression models were used. RESULTS: Preoperative thrombocytosis confirmed in 71 patients (17.5%) was significantly associated with the higher pathological tumor stage, lymph node metastasis, prior bladder cancer diagnosis, and preoperative anemia. With a median post-surgical follow-up period of 33.5 months, 125 patients (30.9%) experienced disease recurrence. The recurrence rate among patients with normal platelet levels was 13.6%, compared with 22.2% in those with preoperative thrombocytosis (p < 0.03). The 5-year RFS estimates reached 36.6% in the thrombocytosis-confirmed group. Multivariate analysis implied that preoperative thrombocytosis was a significant independent prognosticator of both poor RFS (HR 2.22, 95% CI 1.14-4.31, p = 0.02) and CSS (HR 2.48, 95% CI 1.14-3.09, p = 0.01). CONCLUSIONS: Patients with a clinically significant elevation of platelet count prior to RNU were more likely to have UTUC with advanced tumor stages and lymph node metastases. Preoperative thrombocytosis was an independent predictor of RFS and CSS in patients who underwent radical nephroureterectomy. Furthermore, preoperative thrombocytosis may complement and refine UTUC clinical prediction algorithms as an independent indicator of adverse survival outcomes.

Prognostic value of preoperative De Ritis ratio on oncological outcomes in patients with muscle-invasive bladder cancer.

OBJECTIVE: We aimed to assess the prognostic value of De Ritis ratio on oncological outcomes in patients suffering from urothelial bladder cancer and undergoing radical cystectomy (RC). PATIENTS AND METHODS: Analytical cohort comprised a single-center series of 367 patients treated between January 2015 and December 2018. Patients were classified into two groups based on De Ritis ratio (<1.3 [normal] vs. ≥1.3 [high]). Along with the Kaplan-Meier survival probability, cox proportional hazard regression models were used. RESULTS: A total of 299 patients were included, 60.5% of them having a De Ritis ratio of <1.3% and 39.5% with a De Ritis ratio of ≥1.3. Preoperative increased De Ritis ratio was associated with age (p = 0.001), gender (p = 0.044), cancer-related death (p = 0.001), overall death (p = 0.001), and tumor stage (p = 0.001). Multivariate analysis implied that preoperative De Ritis ratio was a significant independent prognosticator of overall survival (HR 0.461; 95% CI 0.335-0.633; p < 0.001) and CSS (HR 0.454; 95% CI 0.330-0.623; p < 0.001). Only tumor stage (HR 1.953; 95% CI 1. 106-3.448; p = 0.021) was independently associated with recurrence-free survival (RFS). De Ritis ratio was not independently associated with RFS in multivariate analyses. During the follow up, a total of 198 (66.2%) patients died, including 173 (57.9%) from BC, 5-year CSS was 45.8%. CONCLUSIONS: De Ritis ratio is an independent prognostic factor of cancer specific and overall survival in patients treated with RC for urothelial BC. RC patients may benefit from the use of the De Ritis ratio as a valid predictive biomarker.

Diagnostic and prognostic impact of preoperative thrombocytosis in muscle invasive bladder cancer: Any role in clinical practice?

BACKGROUND: Since earlier research suggested a link between preoperative thrombocytosis and poor oncological outcomes in several cancers, the significance of platelet count abnormalities in bladder carcinoma (BC) demands for further investigation. OBJECTIVE: To assess the prognostic value of preoperative thrombocytosis (PTC) on survival in patients with bladder carcinoma treated by radical cystectomy (RC). PATIENTS AND METHODS: Analytical cohort comprised a single-center series of 299 patients who underwent RC for bladder carcinoma was evaluated. A platelet count beyond the threshold of 400 × 109 /L was considered thrombocytosis. Along with the Kaplan-Meier survival probability, cox proportional hazard regression models were used. RESULTS: Twenty-eight (9.4%) patients had preoperative thrombocytosis. PTC was associated with gender, tumor stage, tumor grade, lymphovascular invasion, hydronephrosis, anemia (p < 0.001), and hypoalbuminemia (p < 0.001). Preoperative thrombocytosis was strongly linked to worse overall survival (OS) (p = 0.002), and cancer specific survival (CSS) (p = 0.004), according to the Kaplan-Meier method. Throughout the follow-up, a total of 198 (66.2%) patients died, including 170 (56.9%) from BC. For this study population 5-year CSS was 45.8%. Preoperative thrombocytosis was not independently associated with OS (HR 1.168; 95% CI 0.740-1.844; p = 0.504) or CSS (HR 1.060; 95% CI 0.649-1.730; p = 0.816) in multivariate Cox regression analysis. Only tumor stage (HR 2.558; 95% CI 1.675-3.908; p < 0.001), hydronephrosis (HR 1.614; 95% CI 1.173-2.221; p = 0.003), lymph node metastasis (HR 1.555; 95% CI 1.076-2-2.248; p = 0.019), anemia (HR 1.454; 95% CI 1.034-2.046; p = 0.032) and ASA grade (HR 1.375; 95% CI 1.006-1.879; p = 0.046) were independently associated with CSS. CONCLUSIONS: In a single-center study of consecutive patients who underwent radical cystectomy for bladder cancer, preoperative thrombocytosis was unable to predict outcomes.

Prognostic significance of tumor multifocality on outcomes in patients with upper tract urothelial carcinoma after radical nephroureterectomy: A cohort study.

To identify the prognostic impact of tumor multifocality on upper tract urothelial carcinoma (UTUC) outcomes in patients treated with radical nephroureterectomy (RNU). Study included 342 consecutive patients with UTUC. Tumor multifocality was defined as the synchronous presence of 2 or more pathologically confirmed tumors in any upper urinary tract location. Cox regression analyses were used to address recurrence-free (RFS) and cancer-specific survival (CSS) estimates. Tumor multifocality was significantly associated with a history of previous non-muscle invasive bladder cancer (P < 0.001), tumor size (P < 0.001), gender (P = 0.009), tumor location (P = 0.005), and anemia (P = 0.01). The Kaplan-Meier method showed that tumor multifocality was significantly associated with worse recurrence-free survival (P < 0.001, log rank). Using multivariate analysis, tumor multifocality (HR, 2.86; 95% CI, 2.06 - 3.99; P < 0.001) was independently associated with recurrence free survival. During the follow-up, a total of 128 (37.4%) patients died, including 92 (28.2%) from UTUC. However, tumor multifocality was not associated with CSS (HR, 1.29; 95% CI, 0.89 - 1.96; P = 0.21) in univariate Cox regression analyses. Tumor stage (HR, 11.1; 95% CI, 3.64 - 33.8; P < 0.001), lymph node status (HR, 2.04, 95% CI, 1.05 - 3.94; P = 0.03) and preoperative anemia (HR, 3.50, 95% CI, 2.02 - 6.08; P < 0.001) were the only independent predictors associated with worse cancer-specific survival. Tumor multifocality is an independent prognostic factor of disease recurrence in patients treated with RNU for UTUC. Tumor multifocality is unable to predict cancer specific survival in a single-center series of consecutive patients who were treated with RNU.
