RESUMO
The overall survival (OS) improvement after the advent of several novel systemic therapies, designed for treatment of metastatic urothelial carcinoma of the urinary bladder (mUCUB), is not conclusively studied in either contemporary UCUB patients and/or non-UCUB patients. Within the Surveillance, Epidemiology, and End Results database, contemporary (2017-2020) and historical (2000-2016) systemic therapy-exposed metastatic UCUB and, subsequently, non-UCUB patients were identified. Separate Kaplan-Meier and multivariable Cox regression (CRM) analyses first addressed OS in mUCUB and, subsequently, in metastatic non-UCUB (mn-UCUB). Of 3443 systemic therapy-exposed patients, 2725 (79%) harbored mUCUB versus 709 (21%) harbored mn-UCUB. Of 2725 mUCUB patients, 582 (21%) were contemporary (2017-2020) versus 2143 (79%) were historical (2000-2016). In mUCUB, median OS was 11 months in contemporary versus 8 months in historical patients (Δ = 3 months; p < .0001). After multivariable CRM, contemporary membership status (2017-2020) independently predicted lower overall mortality (OM; hazard ratio [HR] = 0.68, 95% confidence interval [CI] = 0.60-0.76; p < .001). Of 709 mn-UCUB patients, 167 (24%) were contemporary (2017-2020) and 542 (76%) were historical (2000-2016). In mn-UCUB, median OS was 8 months in contemporary versus 7 months in historical patients (Δ = 1 month; p = .034). After multivariable CRM, contemporary membership status (2017-2020) was associated with HR of 0.81 (95% CI = 0.66-1.01; p = .06). In conclusion, contemporary systemic therapy-exposed metastatic patients exhibited better OS in UCUB. However, the magnitude of survival benefit was threefold higher in mUCUB and approximated the survival benefits recorded in prospective randomized trials of novel systemic therapies.
RESUMO
BACKGROUND: In incidental prostate cancer (IPCa), elevated other-cause mortality (OCM) may obviate the need for active treatment. We tested OCM rates in IPCa according to treatment type and cancer grade and we hypothesized that OCM is significantly higher in not-actively-treated patients. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2015), IPCa patients were identified. Smoothed cumulative incidence plots as well as multivariable competing risks regression models were fitted to address OCM after adjustment for cancer-specific mortality (CSM). RESULTS: Of 5121 IPCa patients, 3655 (71%) were not-actively-treated while 1466 (29%) were actively-treated. Incidental PCa not-actively-treated patients were older and exhibited higher proportion of Gleason sum (GS) 6 and clinical T1a stage. In smoothed cumulative incidence plots, 5-year OCM was 20% for not-actively-treated versus 8% for actively-treated patients. Conversely, 5-year CSM was 5% for not-actively-treated versus 4% for actively-treated patients. No active treatment was associated with 1.4-fold higher OCM, even after adjustment for age, cancer characteristics, and CSM. According to GS, OCM reached 16%, 27%, and 35% in GS 6, 7, and 8-10 not-actively-treated IPCa patients, respectively and exceeded CSM recorded for the same three groups (2%, 6%, and 28%, respectively). CONCLUSION: Our results quantified OCM rates, confirming that in not-actively-treated IPCa patients OCM is indeed significantly higher than in their actively-treated counterparts (HR: 1.4). These observations validate the use of no active treatment in IPCa patients, in whom OCM greatly surpasses CSM (20% vs. 5%).

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.

BACKGROUND: In contemporary surgically treated patients with localized high-grade (G3 or G4) clear-cell renal cell carcinoma (ccRCC), it is not known whether presence of sarcomatoid dedifferentiation is an independent predictor and/or an effect modifier, when cancer-specific mortality (CSM) represents an endpoint. METHODS: Within the Surveillance, Epidemiology, and End Results database, all surgically treated localized high-grade ccRCC patients treated between 2010 and 2020 were identified. Univariable and multivariable Cox-regression models were used. RESULTS: In 18,853 surgically treated localized high-grade (G3 or G4) ccRCC patients, 5-year CSM-free survival was 87% (62% vs. 88% with vs. without sarcomatoid dedifferentiation, p < 0.001). Presence of sarcomatoid dedifferentiation was an independent predictor of higher CSM (hazard ratio [HR] 1.8, p < 0.001). In univariable survival analyses predicting CSM, presence versus absence of sarcomatoid dedifferentiation in G3 versus G4 yielded the following hazard ratios: HR 1.0 in absent sarcomatoid dedifferentiation in G3; HR 2.7 (p < 0.001) in absent sarcomatoid dedifferentiation in G4; HR 3.9 (p < 0.001) in present sarcomatoid dedifferentiation in G3; HR 5.1 (p < 0.001) in present sarcomatoid dedifferentiation in G4. Finally, in multivariable Cox-regression analyses, the interaction terms defining present versus absent sarcomatoid dedifferentiation in G3 versus G4 represented independent predictors of higher CSM. CONCLUSIONS: In contemporary surgically treated patients with localized high-grade ccRCC, sarcomatoid dedifferentiation is not only an independent multivariable predictor of higher CSM, but also interacts with tumor grade and results in even better ability to predict CSM.

OBJECTIVE: To address cancer-specific mortality free-survival (CSM-FS) differences in patients with urothelial carcinoma of the urinary bladder (UCUB) vs non-UCUB who underwent trimodal therapy (TMT), according to organ confined (OC: T2N0M0) vs non-organ confined (NOC: T3-4NanyM0 or TanyN1-3M0) clinical stages. PATIENTS AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified patients with cT2-T4N0-N3M0 bladder cancer treated with TMT, defined as the combination of transurethral resection of bladder tumour, chemotherapy, and radiotherapy. Temporal trends described TMT use over time. Kaplan-Meier plots and multivariable Cox regression (MCR) models addressed CSM in UCUB vs non-UCUB according to OC vs NOC stages. RESULTS: Of 5130 assessable TMT-treated patients, 425 (8%) harboured non-UCUB vs 4705 (92%) who had UCUB. The TMT rates increased for patients with OC UCUB from 92.4% to 96.8% (estimated annual percentage change of 0.4%, P < 0.001), but not in the NOC stages (P = 0.3). In the OC stage, the median CSM-FS was 36 months in patients with non-UCUB vs 60 months in those with UCUB, respectively (P = 0.01). Conversely, in the NOC stage, the median CSM-FS was 23 months both in UCUB and non-UCUB (P = 0.9). In the MCR models addressing OC stage, non-UCUB histology independently predicted higher CSM (hazard ratio 1.45, P = 0.004), but not in the NOC stage (P = 0.9). CONCLUSION: In OC UCUB, TMT rates have increased over time in a guideline-consistent fashion. Patients with OC non-UCUB treated with TMT showed a CSM disadvantage relative to OC UCUB. In the NOC stage, use of TMT resulted in dismal CSM, regardless of UCUB vs non-UCUB histology.
RESUMO
BACKGROUND: We hypothesized that the evolving treatment paradigms recommended based on phase III trials may have translated into improved overall survival (OS) in contemporary community-based patients with clear-cell metastatic renal cell carcinoma (ccmRCC) undergoing active treatment. PATIENTS AND METHODS: Within the SEER database, contemporary (2017-2020) and historical (2010-2016) patients with ccmRCC treated with either systemic therapy (ST), cytoreductive nephrectomy (CN), or both (ST+CN) were identified. Univariable and multivariable Cox-regression models were used. RESULTS: Overall, 993 (32%) contemporary versus 2,106 (68%) historical patients with ccmRCC were identified. Median OS was 41 months in contemporary versus 25 months in historical patients (Δ=16 months; P<.001). In multivariable Cox-regression analyses, contemporary membership was independently associated with lower overall mortality (hazard ratio [HR], 0.7; 95% CI, 0.6-0.8; P<.001). In patients treated with ST alone, median OS was 17 months in contemporary versus 10 months in historical patients (Δ=7 months; P<.001; multivariable HR, 0.7; P=.005). In patients treated with CN alone, median OS was not reached in contemporary versus 33 months in historical patients (Δ=not available; P<.001; multivariable HR, 0.7; P<.001). In patients treated with ST+CN, median OS was 38 months in contemporary versus 26 months in historical patients (Δ=12 months; P<.001; multivariable HR, 0.7; P=.003). CONCLUSIONS: Contemporary community-based patients with ccmRCC receiving active treatment clearly exhibited better survival than their historical counterparts, when examined as one group, as well as when examined as separate subgroups according to treatment type. Treatment advancements of phase III trials seem to be applied appropriately outside of centers of excellence.
RESUMO
OBJECTIVE: The cT1a vs. cT1b substratification was introduced in 1992 but never formally tested since. We tested the discriminative ability of cT1a vs. cT1b substaging on cancer-specific survival (CSS) in contemporary incidental prostate cancer (PCa) patients. DESIGN, SETTING AND PARTICIPANTS: Incidental (cT1a/cT1b) PCa patients were identified within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Kaplan-Meier estimates, as well as uni- and multivariable Cox regression models predicted CSS at five years. Subgroup analyses addressed CSS at five years according to active vs. no local treatment (NLT) as well as Gleason score sum (GS; 6 vs. 7 vs. ≥ 8). RESULTS AND LIMITATION: We identified a total of 5,155 incidental prostate cancer patients of which 3,035 (59%) were stage cT1a vs. 2,120 (41%) were stage cT1b. In all incidental PCa patients, CSS at five years was 95% (95% CI 0.94-0.96). In cT1a patients, CSS at five years was 98 vs. 90% in cT1b patients (p < 0.001). In multivariable Cox regression analyses, cT1b independently predicted 2.8-fold higher CSM than cT1a (HR 2.5, 95% CI 1.8-3.6, p < 0.001) for incidental PCa patients who underwent NLT. In subgroup analyses, cT1b represented an independent predictor of higher CSM in GS ≥ 8 (HR 3.0, 95% CI 1.4-6.2, p = 0.003), and GS 7 (HR 3.9, 95% CI 1.6-9.7 p = 0.002) patients who underwent NLT. For actively treated patients, cT1b was not independently associated with worse CSM. CONCLUSION: The historical subclassification of cT1a vs. cT1b in incidental PCa patients displayed a strong ability to discriminate CSS in contemporary GS 7 and GS ≥ 8 patients who underwent NLT. However, no statistically significant difference was recorded in actively treated patients. In consequence, the importance of the current substage stratification predominantly applies to GS ≥ 8 patients who undergo a non-active treatment approach.

PURPOSE: Radiotherapy (RT) represents a treatment option for small renal masses with proven feasibility and tolerability. However, it has never been directly compared to partial nephrectomy (PN) with cancer-specific mortality (CSM) as an endpoint. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified T1aN0M0 renal cell carcinoma (RCC) patients treated with RT or PN. We relied on 1:1 propensity score matching (PSM) for age, tumor size and histology. Subsequently, cumulative incidence plots and multivariable competing risks regression (CRR) models were fitted. The same methodology was then re-applied to a subset of patients with tumor size 21-40 mm. RESULTS: Of 40,355 patients with T1aN0M0 RCC, 40,262 underwent PN (99.8%) vs 93 underwent RT (0.2%). RT patients were older (median age 72 vs 60 years, p < 0.001) and harbored larger tumor size (median size 28 vs 25 mm, p < 0.001) and a higher proportion of non-clear cell RCC (49% vs 22%, p < 0.001). After 1:1 PSM (92 RT versus 92 PN patients), cumulative incidence plots' derived CSM was 21.3 vs 4%, respectively. In multivariable CRR models, RT independently predicted higher CSM (hazard ratio (HR) 4.3, p < 0.001). In the subgroup with tumor size 21-40 mm, after 1:1 PSM (72 RT versus 72 PN patients), cumulative incidence plots derived CSM was 21.3% vs 4%, respectively. In multivariable CRR models, RT also independently predicted higher CSM (HR 4.7, p = 0.001). CONCLUSIONS: In T1aN0M0 RCC patients, relative to PN, RT is associated with significantly higher absolute and relative CSM, even in patients with tumor size 21-40 mm.

BACKGROUND: It is unknown whether the stage of the primary may influence the survival (OS) of metastatic upper tract urothelial carcinoma (mUTUC) patients treated with nephroureterectomy (NU) and systemic therapy (ST). We tested this hypothesis within a large-scale North American cohort. METHODS: Within Surveillance Epidemiology and End Results database 2000-2020, all mUTUC patients treated with ST+NU or with ST alone were identified. Kaplan-Maier plots depicted OS. Multivariable Cox regression (MCR) models tested for differences between ST+NU and ST alone predicting overall mortality (OM). All analyses were performed in localized (T1-T2) and then repeated in locally advanced (T3-T4) patients. RESULTS: Of all 728 mUTUC patients, 187 (26%) harbored T1-T2 vs 541 (74%) harbored T3-T4. In T1-T2 patients, the median OS was 20 months in ST+NU vs 10 months in ST alone. Moreover, in MCR analyses that also relied on 3 months' landmark analyses, the combination of ST+NU independently predicted lower OM (HR 0.37, p < 0.001). Conversely, in T3-T4 patients, the median OS was 12 in ST+NU vs 10 months in ST alone. Moreover, in MCR analyses that also relied on 3 months' landmark analyses, the combination of ST+NU was not independently associated with lower OM (HR 0.85, p = 0.1). CONCLUSIONS: In mUTUC patients, treated with ST, NU drastically improved survival in T1-T2 patients, even after strict methodological adjustments (multivariable and landmark analyses). However, this survival benefit did not apply to patients with locally more advanced disease (T3-T4).

BACKGROUND: We examined the effect of disease-free interval (DFI) duration on cancer-specific mortality (CSM)-free survival, otherwise known as the effect of conditional survival, in radical urethrectomy nonmetastatic primary urethral carcinoma (PUC) patients. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database 2000-2020, patient (age, sex, race/ethnicity, and marital status) and tumor (stage and histology) characteristics, as well as systemic therapy exposure status of nonmetastatic PUC patients were tabulated. Conditional survival estimates at 5-year were assessed based on DFI duration and according to stage at presentation (T1 -2N0 vs. T3-4N0-2). RESULTS: Of all 512 radical urethrectomy PUC patients, 278 (54%) harbored T1-2N0 stage versus 234 (46%) harbored T3-4N0-2 stage. In 512 PUC patients, 5-year CSM-free survival at initial diagnosis was 61.8%. Provided a DFI duration of 36 months, 5-year CSM-free survival was 85.6%. In 278 T1-2N0 PUC patients, 5-year CSM-free survival at initial diagnosis was 68.4%. Provided a DFI duration of 36 months, 5-year CSM-free survival was 86.9%. In 234 T3-4N0-2 PUC patients, 5-year CSM-free survival at initial diagnosis was 53.8%. Provided a DFI duration of 36 months, 5-year CSM-free survival was 83.6%. CONCLUSIONS: Although intuitively, clinicians and patients are well aware of the concept that increasing DFI duration improves survival probability, only a few clinicians can accurately estimate the magnitude of survival improvement, as was done within the current study. Such information is crucial to survivors, especially in those diagnosed with rare malignancies, where the survival estimation according to DFI duration is even more challenging.

BACKGROUND: In 2021, the International Germ Cell Cancer Collaborative Group (IGCCCG) Update Consortium reported improved overall survival (OS) rates in a modern cohort of metastatic non-seminoma testis cancer patients within each of the IGCCCG prognosis groups (96% in good vs. 89% in intermediate vs. 67% in poor), compared to the previous IGCCCG publication (92% in good vs. 80% in intermediate vs. 48% in poor). We hypothesized that a similar survival improvement may apply to a contemporary North-American population-based cohort of non-seminoma testis cancer patients. PATIENTS AND METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (2010-2018) was used. Kaplan-Meier plots and multivariable Cox regression models tested the effect of IGCCCG prognosis groups on overall mortality (OM). RESULTS: Of 1672 surgically treated metastatic non-seminoma patients, 778 (47%) exhibited good vs. 251 (15%) intermediate vs. 643 (38%) poor prognosis. In the overall cohort, five-year OS rate was 94% for good prognosis vs. 87% for intermediate prognosis vs. 65% for poor prognosis. In multivariable Cox regression models predicting OM, intermediate (Hazard ratio [HR] 2.4, 95% confidence interval [CI] 1.4-3.9, P < 0.001) and poor prognosis group (HR 6.6, 95% CI 1.0-1.0, P < 0.001) were independent predictors of higher OM, relative to good prognosis group. CONCLUSIONS: The survival improvement reported by the IGCCCG Update Consortium is also operational in non-seminoma testis cancer patients within the most contemporary SEER database. This observation indicates that the survival improvement is not only applicable to centres of excellence, but also applies to other institutions at large.

BACKGROUND: In nonmetastatic pelvic liposarcoma patients, it is unknown whether married status is associated with better cancer-control outcome defined as cancer-specific mortality (CSM). We addressed this knowledge gap and hypothesized that married status is associated with lower CSM rates in both male and female patients. METHODS: Within the Surveillance, Epidemiology, and End Results database (2000-2020), nonmetastatic pelvic liposarcoma patients were identified. Kaplan-Meier plots and univariable and multivariable Cox regression models (CRMs) predicting CSM according to marital status were used in the overall cohort and in male and female subgroups. RESULTS: Of 1078 liposarcoma patients, 764 (71%) were male and 314 (29%) female. Of 764 male patients, 542 (71%) were married. Conversely, of 314 female patients, 192 (61%) were married. In the overall cohort, 5-year cancer-specific mortality-free survival (CSM-FS) rates were 89% for married versus 83% for unmarried patients (Δ = 6%). In multivariable CRMs, married status did not independently predict lower CSM (hazard ratio [HR]: 0.74, p = 0.06). In males, 5-year CSM-FS rates were 89% for married versus 86% for unmarried patients (Δ = 3%). In multivariable CRMs, married status did not independently predict lower CSM (HR: 0.85, p = 0.4). In females, 5-year CSM-FS rates were 88% for married versus 79% for unmarried patients (Δ = 9%). In multivariable CRMs, married status independently predicted lower CSM (HR: 0.58, p = 0.03). CONCLUSIONS: In nonmetastatic pelvic liposarcoma patients, married status independently predicted lower CSM only in female patients. In consequence, unmarried female patients should ideally require more assistance and more frequent follow-up than their married counterparts.

BACKGROUND: It is unknown whether 5-year overall survival (OS) differs and to what extent between the American Joint Committee on Cancer stage III non-seminoma testicular germ cell tumor (NS-TGCT) patients and simulated age-matched male population-based controls, according to race/ethnicity groups. METHODS: We identified newly diagnosed (2004-2014) stage III NS-TGCT patients within the Surveillance Epidemiology and End Results database 2004-2019. For each case, we simulated an age-matched male control (Monte Carlo simulation), relying on Social Security Administration (SSA) Life Tables with 5 years of follow-up. We compared OS rates between stage III NS-TGCT patients and simulated age-matched male population-based controls, according to race/ethnicity groups (Caucasian, Hispanic, Asian/Pacific Islander and African American). Both, cancer-specific mortality (CSM) and other-cause mortality (OCM) were computed. RESULTS: Of 2054 stage III NS-TGCT patients, 60% were Caucasians versus 33% Hispanics versus 4% Asians/Pacific Islanders versus 3% African Americans. The 5-year OS difference between stage III NS-TGCT patients versus simulated age-matched male population-based controls was highest in Asians/Pacific Islanders (64 vs. 99%, Δ = 35%), followed by African Americans (66 vs. 97%, Δ = 31%), Hispanics (72 vs. 99%, Δ = 27%), and Caucasians (76 vs. 98%, Δ = 22%). The 5-year CSM rate was highest in Asians/Pacific Islanders (32%), followed by African Americans (26%), Hispanics (25%), and Caucasians (20%). The 5-year OCM rate was highest in African Americans (8%), followed by Caucasians (4%), Asians/Pacific Islanders (4%), and Hispanics (2%). CONCLUSION: Relative to SSA Life Tables, the highest 5-year OS disadvantage applied to stage III NS-TGCT Asian/Pacific Islander race/ethnicity group, followed by African American, Hispanic and Caucasian, in that order.
RESUMO
BACKGROUND: This study aimed to test the prognostic significance of pathologically confirmed lymph node invasion in metastatic renal cell carcinoma (mRCC) patients in this immunotherapy era. METHODS: Surgically treated mRCC patients were identified in the Surveillance, Epidemiology, and End Results (SEER) database between 2010 and 2018. Kaplan-Meier plots and multivariable Cox-regression models were fitted to test for differences in cancer-specific mortality (CSM) and overall mortality (OM) according to N stage (pN0 vs pN1 vs. pNx). Subgroup analyses addressing pN1 patients tested for CSM and OM differences according to postoperative systemic therapy status. RESULTS: Overall, 3149 surgically treated mRCC patients were identified. Of these patients, 443 (14%) were labeled as pN1, 812 (26%) as pN0, and 1894 (60%) as pNx. In Kaplan-Meier analyses, the median CSM-free survival was 15 months for pN1 versus 40 months for pN0 versus 35 months for pNx (P < 0.001). In multivariable Cox regression analyses, pN1 independently predicted higher CSM (hazard ratio [HR], 1.88; P < 0.01) and OM (HR, 1.95; P < 0.01) relative to pN0. In sensitivity analyses addressing pN1 patients, postoperative systemic therapy use independently predicted lower CSM (HR, 0.73; P < 0.01) and OM (HR, 0.71; P < 0.01). CONCLUSION: Pathologically confirmed lymph node invasion independently predicted higher CSM and OM for surgically treated mRCC patients. For pN1 mRCC patients, use of postoperative systemic therapy was associated with lower CSM and OM. Consequently, N stage should be considered for individual patient counseling and clinical decision-making. Consort diagram of the study population.

BACKGROUND: This study aimed to test for temporal trends of in-hospital venous thromboembolism (VTE) and pulmonary embolism (PE) after major urologic cancer surgery (MUCS). METHODS: In the Nationwide Inpatient Sample (NIS) database (2010-2019), this study identified non-metastatic radical cystectomy (RC), radical prostatectomy (RP), radical nephrectomy (RN), and partial nephrectomy (PN) patients. Temporal trends of VTE and PE and multivariable logistic regression analyses (MLR) addressing VTE or PE, and mortality with VTE or PE were performed. RESULTS: Of 196,915 patients, 1180 (1.0%) exhibited VTE and 583 (0.3%) exhibited PE. The VTE rates increased from 0.6 to 0.7% (estimated annual percentage change [EAPC] + 4.0%; p = 0.01). Conversely, the PE rates decreased from 0.4 to 0.2% (EAPC - 4.5%; p = 0.01). No difference was observed in mortality with VTE (EAPC - 2.1%; p = 0.7) or with PE (EAPC - 1.2%; p = 0.8). In MLR relative to RP, RC (odds ratio [OR] 5.1), RN (OR 4.5), and PN (OR 3.6) were associated with higher VTE risk (all p < 0.001). Similarly in MLR relative to RP, RC (OR 4.6), RN (OR 3.3), and PN (OR 3.9) were associated with higher PE risk (all p < 0.001). In MLR, the risk of mortality was higher when VTE or PE was present in RC (VTE: OR 3.7, PE: OR 4.8; both p < 0.001) and RN (VTE: OR 5.2, PE: OR 8.3; both p < 0.001). CONCLUSIONS: RC, RN, and PN predisposes to a higher VTE and PE rates than RP. Moreover, among RC and RN patients with either VTE or PE, mortality is substantially higher than among their VTE or PE-free counterparts.

PURPOSE: To test for regional differences in clear cell metastatic renal cell carcinoma (ccmRCC) patients across the USA. METHODS: The Surveillance, Epidemiology, and End Results (SEER) database (2000-2018) was used to tabulate patient (age at diagnosis, sex, race/ethnicity), tumor (N stage, sites of metastasis) and treatment characteristics (proportions of nephrectomy and systemic therapy), according to 12 SEER registries. Multinomial regression models, as well as multivariable Cox regression models, tested the overall mortality (OM) adjusting for those patient, tumor and treatment characteristics. RESULTS: In 9882 ccmRCC patients, registry-specific patient counts ranged from 4025 (41%) to 189 (2%). Differences across registries existed for sex (24-36% female), race/ethnicity (1-75% non-Caucasian), N stage (N1 25-35%, NX 3-13%), proportions of nephrectomy (44-63%) and systemic therapy (41-56%). Significant inter-registry differences remained after adjustment for proportions of nephrectomy (46-63%) and systemic therapy (35-56%). Unadjusted 5-year OM ranged from 73 to 85%. In multivariable analyses, three registries exhibited significantly higher OM (SEER registry 5: hazard ratio (HR) 1.20, p = 0.0001; SEER registry 7:HR 1.15, p = 0.008M SEER registry 10: HR 1.15, p = 0.04), relative to the largest reference registry (n = 4025). CONCLUSION: Important regional differences including patient, tumor and treatment characteristics exist, when ccmRCC patients included in the SEER database are studied. Even after adjustment for these characteristics, important OM differences persisted, which may require more detailed analyses to further investigate these unexpected differences.

BACKGROUND: Erectile dysfunction (ED) is widely considered as an early manifestation of cardiovascular diseases (CVDs), sharing similar risk factors. AIM: Assess rates and predictors of developing CVD and/or hypertension (HTN) over a long-term follow-up period using user-friendly and clinically reliable tools in men presenting with ED but without CVD/HTN or known vascular risk factors at baseline. METHODS: Data from 108 patients presenting between 2005 and 2011 with ED were analyzed. All patients were free from CVD and/or HTN (CVD/HTN) at baseline. Patients completed the International Index of Erectile Function (IIEF) at baseline and were followed up every 6 months with clinical assessment or phone interview. Kaplan-Meier analyses estimated the probability of developing CVD/HTN over time. Cox-regression models tested the association between patient baseline characteristics (for example, age, Charlson Comorbidity Index, baseline IIEF-EF, ED severity, alcohol intake, smoking), response to phosphodiesterase type-5 inhibitors (PDE5is), and the risk of developing CVD/HTN. RESULTS: Of all, 43 (40%) patients showed IIEF-EF scores suggestive of severe ED; 37 (39%) and 59 (61%) were nonresponders and responders to PDE5i, respectively. Median (interquartile range) age was 51 (41, 61) years. Median (interquartile range) follow-up was 95 (86-106) months. Overall, the estimated risk of developing CVD/HTN was 15% (95% confidence interval [CI]: 9-27) at 10-year assessment. Men with baseline severe ED had a higher risk of developing CVD/HTN (34%; 95% CI: 17-59, P = .03) at 10 years than patients with mild to moderate ED (5% [95% CI: 2-14]). At the Cox regression analysis, severe ED (Hazard ratio [HR], 4.62; 95% CI: 1.43, 8.89; P = .01) and baseline IIEF-EF score (HR, 0.92; 95% CI: 0.86, 0.99; P = .02) were associated to the risk of CVD/HTN overtime. Conversely, age and nonresponders to PDE5is (HR, 0.92; 95% CI: 0.32, 2.68; P = .9) were not associated to a risk of CVD/HTN over time. CLINICAL IMPLICATIONS: The use of an easy and user-friendly tool, as the IIEF-EF domain score, would allow to reliably assess which men with ED at first presentation may deserve a different, more specific and detailed cardiologic investigation to prevent inauspicious CV events. STRENGTHS & LIMITATIONS: A single-center-based, observational longitudinal study, raising the possibility of selection biases are the main limits. CONCLUSIONS: Patients with severe ED and lower baseline IIEF-EF but no vascular risk factors at first presentation have more than 30% risk of developing CVD/HTN in 10-year time. Those patients may benefit from medical preventive strategies to lowering the risk of CV events and HTN. Pozzi E, Capogrosso P, Boeri L, et al.

PURPOSE: The role of lymphadenectomy and the optimal lymph node count (LNC) cut-off in nonmetastatic adrenocortical carcinoma (nmACC) are unclear. METHODS: Within the Surveillance, Epidemiology, and End Results (SEER) database, surgically treated nmACC patients with T2-4 stages were identified between 2004 and 2020. We tested for cancer-specific mortality (CSM) differences according to pathological N-stage (pN0 vs. pN1) and two previously recommended LNC cut-offs (≥4 vs. ≥5) were tested in pN0 and subsequently in pN1 subgroups in Kaplan-Meier plots and multivariable Cox regression models. RESULTS: Of 710 surgically treated nmACC patients, 185 (26%) underwent lymphadenectomy and were assessable for further analyses based on available LNC data. Of 185 assessable patients, 152 (82%) were pN0 and 33 (18%) were pN1. In Kaplan-Meier analyses, CSM-free survival was 74 vs. 14 months (Δ 60 months, P ≤ 0.001) in pN0 vs. pN1 patients, respectively. In multivariable analyses, pN1 was an independent predictor of higher CSM (HR:3.13, P < 0.001). In sensitivity analyses addressing pN0, LNC cut-off of ≥4 was associated with lower CSM (multivariable hazard ratio [HR]: 0.52; Pâ¯=â¯0.002). In sensitivity analyses addressing pN0, no difference was recorded when a LNC cut-off of ≥5 was used (HR:0.60, Pâ¯=â¯0.09). In pN1 patients, neither of the cut-offs (≥4 and ≥5) resulted in a statistically significant stratification of CSM rate, and neither reached independent predictor status (all P > 0.05). CONCLUSIONS: Lymphadenectomy provides a prognostic benefit in nmACC patients and identifies pN1 patients with dismal prognosis. Conversely, in pN0 patients, a LNC cut-off ≥4 identifies those with particularly favorable prognosis.
