BACKGROUND: Identifying those of patients with metastatic renal cell carcinoma (mRCC) who are most likely to benefit from cytoreductive nephrectomy (CN) is challenging. We tested the association between preoperative value of Systemic Immune-Inflammation Index (SII) and overall survival (OS) as well as cancer-specific survival (CSS) in mRCC patients treated with CN. METHODS: mRCC patients treated with CN at different institutions were included. After assessing for the optimal pretreatment SII cut‐off value, we found 710 to have the maximum Youden Index value. The overall population was therefore divided into two SII groups using this cut‐off (low, <710 vs. high, ≥710). Univariable and multivariable Cox regression analyses tested the association SII and OS as well as CSS. The discrimination of the model was evaluated with the Harrel's Concordance Index (C-Index). The clinical value of the SII was evaluated with decision curve analysis (DCA). RESULTS: Among 613 mRCC patients, 298 (49%) patients had a SII≥710. Median follow-up was 31 (IQR 16-58) months. On univariable analysis, high preoperative serum SII was significantly associated with worse OS (HR: 1.28, 95% CI: 1.07-1.54, P=0.01) and CSS (HR: 1.29, 95% CI: 1.08-1.55, P=0.01). On multivariable analysis, which adjusted for the effect of established clinicopathologic features, SII≥710 was associated with OS (HR: 1.25, 95% CI: 1.04-1.50, P=0.02) and CSS (HR: 1.26, 95% CI: 1.05-1.52, P=0.01). The addition of SII only slightly improved the discrimination of a base model that included established clinicopathologic features (C-index: 0.637 vs. 0.629). On DCA, the inclusion of SII did not improve the net-benefit of the prognostic model. On multivariable analyses, SII≥710 remained independently associated with the worse OS and CSS in IMDC intermediate risk group (both: HR: 1.31, 95% CI: 1.02-1.67, P=0.03). In the subgroup analyses based on the BMI, among patients with BMI ≥ 25, SII was significantly associated with OS (HR: 1.29, 95% CI: 1.04-1.61, P=0.02) and CSS (HR: 1.31, 95% CI: 1.05-1.63, P=0.02). CONCLUSIONS: We found an independent association of high SII prior to CN with unfavorable clinical outcomes, particularly in patients with intermediate risk mRCC and patients with increased BMI. Despite these results, it does not seem to add any prognostic or clinical benefit beyond that obtained by currently available clinicopathologic characteristics as sole worker.

OBJECTIVES: To test contemporary rates and predictors of open conversion at minimally invasive partial nephrectomy (MIPN: laparoscopic or robotic partial nephrectomy). MATERIALS AND METHODS: Within the National Inpatient Sample database (2008-2015) we identified all MIPN patients and patients that underwent open conversion at MIPN. First, estimated annual percentage changes (EAPC) tested temporal trends of open conversion. Second, univariable and multivariable logistic regression models predicted open conversion at MIPN. All models were weighted and adjusted for clustering, as well as all available patient and hospital characteristics. RESULTS: Of 7649 MIPN patients, 287 (3.8%) underwent open conversion. The rates of open conversion decreased over time (from 12 to 2.4%; EAPC: 24.8%; p = 0.004). In multivariable logistic regression models predicting open conversion, patient obesity achieved independent predictor status (OR:1.80; p < 0.001). Moreover, compared to high volume hospitals, medium volume (OR:1.48; p = 0.02) and low volume hospitals (OR:2.11; p < 0.001) were associated with higher rates of open conversion. Last but not least, when the effect of obesity was tested according to hospital volume, the rates of open conversion ranged from 2.2 (non obese patients treated at high volume hospitals) to 9.8% (obese patients treated at low volume hospitals). CONCLUSION: Overall contemporary (2008-2015) rate of open conversion at MIPN was 3.8% and it was strongly associated with patient obesity and hospital surgical volume. In consequence, these two parameters should be taken into account during preoperative patients counselling, as well as in clinical and administrative decision making.

We hypothesized that pT3a stage at nephrectomy can be accurately predicted in cT1N0M0 clear cell-renal cell carcinoma (cc-RCC) patients. Of 236 patients, treated with either partial or radical nephrectomy (2005-2019), 25 (10.6%) harbored pT3a stage. Multivariable logistic regression models predicting pT3a were fitted using age, tumor size, tumor location and exophytic rate. The new model was 81% accurate. In calibration plots, minimal departures from ideal prediction were recorded. In decision curve analyses, a net-benefit throughout all threshold probabilities was recorded relative to the treat-all or treat-none strategies. Using a probability cut-off of 21% for presence of pT3a stage, 38 patients (16.1%) were identified, in whom pT3a rate was 36.8%. Conversely, in 198 patients (83.9%) below that cut-off, the rate of pT3a was 5.6%. Alternative user-defined cut-offs may be selected. The new model more accurately identifies a subgroup of cT1N0M0 cc-RCC patients with substantially higher risk of pT3a stage than average.

BACKGROUND: Recent data showed that North America has the highest incidence of renal cell carcinoma (RCC) worldwide. OBJECTIVE: To assess contemporary gender-, race-, and stage-specific incidence; survival rates; and trends of RCC patients in the USA. DESIGN, SETTING, AND PARTICIPANTS: Within the Surveillance, Epidemiology, and End Results database (2001-2016), all patients aged ≥18 yr with histologically confirmed renal parenchymal tumors were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Age-adjusted incidence rates and 5-yr cancer-specific survival (CSS) rates were estimated. Temporal trends were calculated through Joinpoint regression analyses to describe the average annual percent change (AAPC). RESULTS AND LIMITATIONS: The age-adjusted incidence rate of RCC was 11.3/100 000 person years (AAPC+2.0%, p<0.001). Five-year CSS rates increased from 78.4% to 84.5% (AAPC +0.8%, p<0.001). Male incidence was double that of females (15.5 and 7.7, respectively). CSS marginally favored females (84.5% vs 82.0%), but improved equally in both genders (both AAPC +0.8%). The highest incidence (14.1/100 000 person years, AAPC +2.8%) and lowest survival (80.1%) were recorded in non-Hispanic American Indian/Alaska Native populations. T1aN0M0 had the highest incidence rates (4.6/100 000 person years), the highest increase over time (AAPC +3.6%), and the highest CSS (97.6%) of all stages. Limitations include retrospective nature and lack of information on risk factors. CONCLUSIONS: The incidence of RCC increased significantly from 2001 to 2016, and 5-yr CSS after RCC improved. This was mainly due to T1aN0M0 tumors that showed the highest increase in the incidence and highest CSS. Unfavorable outcomes in specific ethnic groups warrant further research. PATIENT SUMMARY: We examined contemporary incidence and cancer-specific survival rates of kidney cancer. Males had double the incidence rates of females, but lower survival. Natives showed the highest incidence rates and the lowest survival rates. Small renal masses showed the highest incidence and survival rates.

BACKGROUND: Optimal management of metastatic non-clear cell renal cell carcinoma (non-ccmRCC) remains largely unknown. OBJECTIVE: To test the effect of systemic therapy (ST) and/or cytoreductive nephrectomy (CNT) on overall mortality (OM) in patients with non-ccmRCC. DESIGN, SETTING, AND PARTICIPANTS: Within the Surveillance, Epidemiology and End Results (SEER) registry (2006-2015), we identified patients with papillary, chromophobe, sarcomatoid, and collecting duct metastatic renal cell carcinoma (mRCC). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Temporal trends (estimated annual percentage change [EAPC]), Kaplan-Meier plots, and multivariable Cox regression models were used. RESULTS AND LIMITATIONS: Of 1573 patients with non-ccmRCC, 22%, 25%, 25%, and 28% underwent no treatment, ST, CNT, and CNT with ST, respectively. Between 2006 and 2015, rates of CNT and the combination of CNT and ST decreased (EAPC: -6.3% and -3.2%, respectively). Conversely, rates of no treatment and ST increased over time (EAPC: 4.6% and 7.5%, respectively). In multivariable Cox regression models, relative to no treatment, ST (hazard ratio [HR]: 0.5; p < 0.001), CNT (HR: 0.4; p < 0.001), and CNT with ST (HR: 0.3; p < 0.001) were associated with lower OM. Histological subtypes were associated with OM, relative to papillary renal cell carcinoma (RCC): chromophobe (HR: 0.7; p < 0.01), sarcomatoid (HR: 2.1; p < 0.001), and collecting duct RCC (HR: 1.9; p < 0.001). Limitations include the impossibility to stratify patients according to mRCC risk groups. CONCLUSIONS: Most non-ccmRCC patients are treated with a combination of CNT and ST or CNT alone or ST alone. The rates of ST alone are increasing. Conversely, the rates of combined CNT and ST and CNT alone are decreasing. These observed temporal patterns of treatment rates are counterintuitive with respect to associated OM benefits, where combination of CNT and ST, as well as CNT alone, resulted in the lowest absolute OM, relative to ST alone, or, even worse, no treatment. PATIENT SUMMARY: We investigated the effect of treatment modalities on survival of patients with metastatic non-clear cell renal cell carcinoma. The combination of cytoreductive nephrectomy and systemic therapy confers greater benefit with respect to single treatments alone.

Background: Accurate identification of ideal candidates for cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC) is an unmet need. We tested the association between preoperative value of systemic albumin to globulin ratio (AGR) and overall survival (OS) as well as cancer-specific survival (CSS) in mRCC patients treated with CN. Methods: mRCC patients treated with CN were included. The overall population was therefore divided into two AGR groups using cut-off of 1.43 (low, <1.43 vs. high, ≥1.43). Univariable and multivariable Cox regression analyses tested the association between AGR and OS as well as CSS. The discrimination of the model was evaluated with the Harrel's concordance index (C-index). The clinical value of the AGR was evaluated with decision curve analysis (DCA). Results: Among 613 mRCC patients, 159 (26%) patients had an AGR <1.43. Median follow-up was 31 (IQR: 16-58) months. On univariable analysis, low preoperative serum AGR was significantly associated with both OS (HR: 1.55, 95% CI: 1.26-1.89, P<0.001) and CSS (HR: 1.55, 95% CI: 1.27-1.90, P<0.001). On multivariable analysis, AGR <1.43 was associated with worse OS (HR: 1.51, 95% CI: 1.23-1.85, P<0.001) and CSS (HR: 1.52, 95% CI: 1.24-1.86, P<0.001). The addition of AGR only minimally improved the discrimination of a base model that included established clinicopathologic features (C-index=0.640 vs. C-index=0.629). On DCA, the inclusion of AGR marginally improved the net benefit of the prognostic model. Low AGR remained independently associated with OS and CSS in the IMDC intermediate risk group (HR: 1.52, 95% CI: 1.16-1.99, P=0.002). Conclusions: In our study, low AGR before CN was associated with worse OS and CSS, particularly in intermediate risk patients.

BACKGROUND: The NCCN guidelines recommend active surveillance (AS) as an option for the initial management of cT1a 0-2 cm renal lesions. However, data about comparison between renal cell carcinoma (RCC) 0-2 cm vs. 2.1-4 cm are scarce. METHODS: Within the Surveillance, Epidemiology, and End Results database (2002-2016), 46,630 T1a NanyMany stage patients treated with nephrectomy were identified. Data were tabulated according to histological subtype, tumor grade (low [LG] vs. high [HG]), as well as age category and gender. Additionally, rates of synchronous metastases were quantified. RESULTS: Overall, 69.3 vs. 74.1% clear cell, 21.4 vs. 17.6% papillary, 6.9 vs. 6.8% chromophobe, 2.0 vs. 1.1% sarcomatoid dedifferentiation, 0.2 vs. 0.2% collecting duct histological subtype were identified for respectively 0-2 cm and 2.1-4 cm RCCs. In both groups, advanced age was associated with higher rate of HG clear cell and HG papillary histological subtype. In 0-2 cm vs. 2.1-4 cm RCCs, 13.8% vs. 20.2% individuals operated on harbored HG tumors and were more prevalent in males. Lower synchronous metastases rates were recorded in 0-2 cm RCC and ranged from 0 in respectively multilocular cystic to 0.9% in HG papillary histological subtype. The highest synchronous metastases rates were recorded in sarcomatoid dedifferentiation histological subtype (13.8% and 9.7%) in both groups. CONCLUSIONS: Relative to 2.1-4 cm RCCs, 0-2 cm RCCs harbored lower rates of HG tumors, lower rates of aggressive variant histology and lower rates of synchronous metastases. The indications and demographics of patients selected for AS may be expanded in the future to include younger and healthier patients.

OBJECTIVES: Metabolic syndrome (MetS) and its components (high blood pressure, BMI≥30, altered fasting glucose, low HDL cholesterol and high triglycerides) may undermine early perioperative outcomes after radical prostatectomy (RP). We tested this hypothesis. MATERIALS & METHODS: Within the National Inpatient Sample database (2008-2015) we identified RP patients. The effect of MetS was tested in four separate univariable analyses, as well as in multivariable regression models predicting: 1) overall complications, 2) length of stay, 3) total hospital charges and 4) non-home based discharge. All models were weighted and adjusted for clustering, as well as all available patient and hospital characteristics. RESULTS: Of 91,618 patients: 1) 50.2% had high blood pressure, 2) 8.0% had BMI≥30, 3) 13.0% had altered fasting glucose, 4) 22.8% had high triglycerides and 5) 0.03% had low HDL cholesterol. Respectively, one vs. two vs. three vs. four MetS components were recorded in 36.2% vs. 19.0% vs. 5.5% vs. 0.8% patients. Of all patients, 6.3% exhibited ≥3 components and qualified for MetS diagnosis. The rates of MetS increased over time (EAPC:+9.8%; p < 0.001). All four tested MetS components (high blood pressure, BMI≥30, altered fasting glucose and high triglycerides) achieved independent predictor status in all four examined endpoints. Moreover, a highly statistically significant dose-response was also confirmed for all four tested endpoints. CONCLUSION: MetS and its components consistently and strongly predict early adverse outcomes after RP. Moreover, the strength of the effect was directly proportional to the number of MetS components exhibited by each individual patient, even if formal MetS diagnosis of ≥3 components has not been met.

BACKGROUND: The objective of this study was to test the effect of chemotherapy and/or radical cystectomy (RC) and/or radiotherapy (RT) on survival of patients with non-metastatic small-cell carcinoma of the urinary bladder (SCCUB). MATERIALS AND METHODS: Within the Surveillance, Epidemiology, and End Results registry (2001-2016), we identified patients with non-metastatic (T1-4, N0, M0) SCCUB. Treatment was defined as: chemotherapy alone, chemotherapy + RC, and chemotherapy + RT. Temporal trends, cumulative incidence plots, and multivariable competing risks regression models were used. RESULTS: Of 595 patients with SCCUB, 230 (38.5%), 159 (27%), and 206 (34.5%) were treated with chemotherapy alone, chemotherapy + RC, and chemotherapy + RT, respectively. The rates of chemotherapy + RC increased (estimated annual percentage changes [EAPC], +5.9%; P = .002). Conversely, chemotherapy alone (EAPC, -1.7%; P = .1) and chemotherapy + RT rates decreased (EAPC: -2.2%; P = .08). Overall, 5-year cancer-specific mortality (CSM) rates were 44%, 29%, and 40% for patients treated with chemotherapy alone, chemotherapy + RC, and chemotherapy + RT, respectively (P = .004). Relative to chemotherapy alone, patients treated with chemotherapy + RC experienced lower CSM (hazard ratio, 0.5; P < .001). Conversely, patients treated with chemotherapy + RT did not exhibit any CSM benefit (hazard ratio, 0.8; P = .2), when compared with chemotherapy alone. CONCLUSION: In contemporary patients with SCCUB with non-metastatic disease, the rates of chemotherapy + RC are increasing. Conversely, the rates of combined chemotherapy with RT and chemotherapy alone are decreasing. These patterns of treatment are in agreement with better cancer control in patients with SCCUB. In consequence, until more robust data become available, the combination of chemotherapy and RC should represent the recommended treatment strategy.

OBJECTIVE: The objective of the study is to test the effect of age on cancer-specific mortality (CSM) in patients with urothelial carcinoma of the urinary bladder (UCUB), across all disease stages. MATERIALS AND METHODS: Within the Surveillance, Epidemiology, and End Results (SEER) registry (2004-2016), we identified 207,714 patients. Age was categorized as: below 60 versus 60 to 69 versus 70 to 79 versus 80 years and above. Multivariable competing-risks regression (CRR) models were used according to disease stage (low-risk nonmuscle invasive: TaN0M0 low grade, high-risk nonmuscle invasive: Ta high grade or Tis-1N0M0, muscle invasive: T2-3N0M0, regional: T4N0M0/TanyN1-3M0, and metastatic: TanyNanyM1). RESULTS: Overall, 33,970 (16.4%) versus 52,173 (25.1%) versus 64,537 (31.1%) versus 57,034 (27.4%) patients were below 60 versus 60 to 69 versus 70 to 79 versus 80 years and above, respectively. In multivariable CRR models that focused on low-risk nonmuscle invasive UCUB, advanced age was associated with higher CSM rates (hazard ratio [HR]: 7.04 in patients aged 80 y and above, relative to below 60 y; P<0.001). Moreover, advanced age was also associated with higher CSM rates in high-risk nonmuscle invasive UCUB (HR: 2.77 in patients aged 80 y and above, relative to below 60 y; P<0.001) and in muscle invasive UCUB patients (HR: 1.38 in patients aged 80 y and above, relative to below 60 y; P<0.001). Conversely, lower CSM rates with advanced age were observed in multivariable CRR that focused on regional (HR: 0.91 for patients aged 80 y and above, relative to below 60 y; P=0.02) or metastatic UCUB (HR: 0.75 for patients aged 80 y and above, relative to below 60 y; P<0.001). CONCLUSIONS: The direction and the magnitude of the association between advanced age and CSM in UCUB patients changes according to tumor stage. In low-risk nonmuscle invasive, high-risk nonmuscle invasive, and muscle invasive UCUB, more advanced age is associated with higher CSM rates. Conversely, in regional and metastatic UCUB patients, more advanced age is associated with lower CSM rates.
