Combination of the Preoperative Systemic Immune-Inflammation Index and Monocyte-Lymphocyte Ratio as a Novel Prognostic Factor in Patients with Upper-Tract Urothelial Carcinoma
Background This study aimed to evaluate the clinical significance of the preoperative systemic immune-inflammation index (SII) combined with the monocyte-lymphocyte ratio (MLR) for patients with upper-tract urothelial carcinoma (UTUC). Methods The clinical data of 424 patients who underwent radical nephroureterectomy from January 2007 to June 2017 were analyzed. Kaplan–Meier analyses and Cox proportional hazards models were used to evaluate associations of preoperative systemic immune-inflammatory biomarkers with overall survival (OS), cancer-specific survival (CSS), and progression-free survival (PFS). Moreover, logistic regression preoperative models were applied to predict advanced disease. Results Multivariate analyses showed that SII significantly influenced both OS and CSS (both P  < 0.05), whereas MLR exhibited the most significant association with OS ( P  = 0.008). In particular, simultaneously high SII and MLR values correlated significantly with OS, CSS, and PFS (all P  < 0.05). Logistic regression preoperative models showed that the combination of high SII and high MLR was a significant predictor of non-organ-confined UTUC ( P  = 0.001). Furthermore, Kaplan–Meier analysis showed that the combination of high SII and high MLR was significantly linked with poor OS, CSS, and PFS in non-organ-confined UTUC (all P  < 0.05). Conclusion The study reviewed serum inflammation biomarkers in a subset of patients with UTUC and demonstrated the ability of combined SII and MLR to predict disease progression and survival. Patients with both high SII and high MLR were significantly more likely to have non-organ-confined disease and poor survival outcomes.
Perioperative Complications and In-Hospital Mortality in Partial and Radical Nephrectomy Patients with Heart-Valve Replacement
Background In-hospital mortality and complication rates after partial and radical nephrectomy in patients with history of heart-valve replacement are unknown. Patients and Methods Relying on the National Inpatient Sample (2000–2019), kidney cancer patients undergoing partial or radical nephrectomy were stratified according to presence or absence of heart-valve replacement. Multivariable logistic and Poisson regression models addressed adverse hospital outcomes. Results Overall, 39,673 patients underwent partial nephrectomy versus 94,890 radical nephrectomy. Of those, 248 (0.6%) and 676 (0.7%) had a history of heart-valve replacement. Heart-valve replacement patients were older (median partial nephrectomy 69 versus 60 years; radical nephrectomy 71 versus 63 years), and more frequently exhibited Charlson comorbidity index ≥ 3 (partial nephrectomy 22 versus 12%; radical nephrectomy 32 versus 23%). In partial nephrectomy patients, history of heart-valve replacement increased the risk of cardiac complications [odds ratio (OR) 4.33; p < 0.001), blood transfusions (OR 2.00; p < 0.001), intraoperative complications (OR 1.53; p = 0.03), and longer hospital stay [rate ratio (RR) 1.25; p < 0.001], but not in-hospital mortality ( p = 0.5). In radical nephrectomy patients, history of heart-valve replacement increased risk of postoperative bleeding (OR 4.13; p < 0.001), cardiac complications (OR 2.72; p < 0.001), intraoperative complications (OR 1.53; p < 0.001), blood transfusions (OR 1.27; p = 0.02), and longer hospital stay (RR 1.12; p < 0.001), but not in-hospital mortality ( p = 0.5). Conclusions History of heart-valve replacement independently predicted four of twelve adverse outcomes in partial nephrectomy and five of twelve adverse outcomes in radical nephrectomy patients including intraoperative and cardiac complications, blood transfusions, and longer hospital stay. Conversely, no statistically significant differences were observed in in-hospital mortality.
The Prognostic Significance of Inflammation-Associated Blood Cell Markers in Patients with Upper Tract Urothelial Carcinoma
Background Inflammation-related parameters based on blood cells, including white blood cell (WBC) count, neutrophil–lymphocyte ratio, platelet count, and red cell distribution width (RDW), have been shown to be associated with prognosis in many cancers. However, no previous study evaluated these inflammation-associated markers simultaneously in upper tract urothelial carcinoma (UTUC). Methods A total of 195 patients with UTUC who received radical nephroureterectomy between 2005 and 2010 were included retrospectively as the derivation cohort to investigate the impact of inflammation markers on overall survival (OS) and cancer-specific survival (CSS). In turn, another independent set of 225 patients were used for validation. Finally, we performed survival analysis in the combined cohort consisting of 420 UTUC patients. Results The predictive value of RDW and WBC count on outcome was replicable in different cohorts. Multivariate analysis showed high RDW was independently associated with poor OS ( P  < 0.001), and WBC count was a significant prognosticator for both OS and CSS (both P  < 0.001). In subgroup analysis, we found the prognostic significance of RDW for OS was limited in organ-confined disease (≤pT2 without pN+). More importantly, a clear survival difference can be demonstrated by combining RDW and WBC count with other known prognostic factors in the risk stratification model. Conclusions RDW and WBC count have the advantage of their common accessibility and are useful markers to predict outcome of UTUC in the preoperative setting. RDW and WBC count could provide additional prognostic value and help physicians identify patients at high risk for mortality and formulate individualized treatment strategy.
En Bloc Resection Versus Conventional TURBT for T1HG Bladder Cancer: A Propensity Score-Matched Analysis
BackgroundWe aimed to assess the clinical, oncological, and pathological impact of en bloc resection of bladder tumors (ERBT) compared with conventional transurethral resection of bladder tumors (cTURBT) for pT1 high-grade (HG) bladder cancer.Patients and MethodsWe retrospectively analyzed the record of 326 patients (cTURBT: n = 216, ERBT: n = 110) diagnosed with pT1 HG bladder cancer at multiple institutions. The cohorts were matched by one-to-one propensity scores based on patient and tumor demographics. Recurrence-free survival (RFS), progression-free survival (PFS), cancer-specific survival (CSS), and perioperative and pathologic outcomes were compared. The prognosticators of RFS and PFS were analyzed using the Cox proportional hazard model.ResultsAfter matching, 202 patients (cTURBT: n = 101, ERBT: n = 101) were retained. There were no differences in perioperative outcomes between the two procedures. The 3-year RFS, PFS, and CSS were not different between the two procedures (p = 0.7, 1, and 0.7, respectively). Among patients who underwent repeat transurethral resection (reTUR), the rate of any residue on reTUR was significantly lower in the ERBT group (cTURBT: 36% versus ERBT: 15%, p = 0.029). Adequate sampling of muscularis propria (83% versus 93%, p = 0.029) and diagnostic rates of pT1a/b substaging (90% versus 100%, p < 0.001) were significantly better in ERBT specimen compared with cTURBT specimen. On multivariable analyses, pT1a/b substaging was a prognosticator of disease progression.ConclusionsIn patients with pT1HG bladder cancer, ERBT had similar perioperative and mid-term oncologic outcomes compared with cTURBT. However, ERBT improves the quality of resection and specimen, yielding less residue on reTUR and yielding superior histopathologic information such as substaging.
Open versus Minimally Invasive Nephroureterectomy: Contemporary Analysis from a Wide National Population-Based Database
Background It is generally perceived that minimally invasive nephroureterectomy (MINU), especially in the form of robotic-assisted laparoscopy, is gaining an increasing role in many institutions. Objective The aim of our study was to investigate contemporary trends in the adoption of MINU in the United States compared with open nephroureterectomy (ONU). Methods Patients who underwent ONU or MINU between 2011 and 2021 were retrospectively analyzed using PearlDiver Mariner, an all-payer insurance claims database. International Classification of Diseases diagnosis and procedure codes were used to identify the type of surgical procedure, patients’ characteristics, social determinants of health (SDOH), and perioperative complications. The primary objective assessed different trends and costs in NU adoption, while secondary objectives analyzed factors influencing the postoperative complications, including SDOH. Outcomes were compared using multivariable regression models. Results Overall, 15,240 patients underwent ONU ( n  = 7675) and MINU ( n  = 7565). Utilization of ONU declined over the study period, whereas that of MINU increased from 29 to 72% ( p  = 0.01). The 60-day postoperative complication rate was 23% for ONU and 19% for MINU ( p  < 0.001). At multivariable analysis, ONU showed a significantly higher risk of postoperative complications (odds ratio 1.33, 95% CI 1.20–1.48). Approximately 5% and 9% of patients reported at least one SDOH at baseline for both ONU and MINU ( p  < 0.001). Conclusions Contemporary trend analysis of a large national dataset confirms that there has been a significant shift towards MINU, which is gradually replacing ONU. A minimally invasive approach is associated with lower risk of complications. SDOH are non-clinical factors that currently do not have an impact on the outcomes of nephroureterectomy.
