RESUMO
BACKGROUND: Androgen-receptor pathway inhibitors (ARPIs) have dramatically changed the management of advanced/metastatic prostate cancer (PCa). However, their cardiovascular toxicity remains to be clarified. OBJECTIVE: To analyze and compare the risks of cardiovascular events secondary to treatment of PCa patients with different ARPIs. METHODS: In August 2023, we queried PubMed, Scopus, and Web of Science databases to identify randomized controlled studies (RCTs) that analyze PCa patients treated with abiraterone, apalutamide, darolutamide, and enzalutamide. The primary outcomes of interest were the incidence of cardiac disorder, heart failure, ischemic heart disease (IHD), atrial fibrillation (AF), and hypertension. Network meta-analyses (NMAs) were conducted to compare the differential outcomes of each ARPI plus androgen deprivation therapy (ADT) compared to standard of care (SOC). RESULTS: Overall, 26 RCTs were included. ARPIs were associated with an increased risk of cardiac disorders (RR: 1.74, 95% CI: 1.13-2.68, p = 0.01), heart failure (RR: 2.49, 95% CI: 1.05-5.91, p = 0.04), AF (RR: 2.15, 95% CI: 1.14-4.07, p = 0.02), and hypertension (RR: 2.06, 95% CI: 1.67-2.54, p < 0.01) at grade ≥3. Based on NMAs, abiraterone increased the risk of grade ≥3 cardiac disorder (RR:2.40, 95% CI: 1.42-4.06) and hypertension (RR:2.19, 95% CI: 1.77-2.70). Enzalutamide was associated with the increase of grade ≥3 AF(RR: 3.17, 95% CI: 1.05-9.58) and hypertension (RR:2.30, 95% CI: 1.82-2.92). CONCLUSIONS: The addition of ARPIs to ADT increases the risk of cardiac disorders, including IHD and AF, as well as hypertension. Each ARPI exhibits a distinct cardiovascular event profile. Selecting patients carefully and vigilant monitoring for cardiovascular issues is imperative for those undergoing ARPI + ADT treatment.
RESUMO
Background and objective: The role of pelvic lymph node dissection (PLND) for prostate cancer is still controversial. This study aims to compare the outcomes of PLND between extraperitoneal single-port (SP eRARP) and transperitoneal multiport (MP tRARP) robotic-assisted radical prostatectomy. Methods: This was a retrospective analysis from our single-center database for patients who underwent SP eRARP or MP tRARP with PLND between 2015 and 2023. The primary endpoint was to analyze and compare specific data related to PLND between the two populations by the detection of pN+ patients, the total number of lymph nodes removed, and the number of positive lymph nodes removed. The secondary endpoints included comparing major complications, lymphoceles, and biochemical recurrence between the two cohorts of the study. Key findings and limitations: A total of 293 patients were included, with 85 (29%) undergoing SP eRARP and 208 (71%) undergoing MP tRARP. SP eRARP showed significant differences in PLND extension from MP tRARP, while MP tRARP yielded more lymph nodes (p < 0.001). There were no differences in pN+ patient detection (p = 0.7) or the number of positive lymph nodes retrieved (p = 0.6). The rates of major complications (p = 0.6), lymphoceles (p = 0.2), and biochemical recurrence (p = 0.9) were similar between the two groups. Additionally, SP eRARP had shorter operative time (p = 0.045), hospital stay (p < 0.001), and less postoperative pain at discharge (p = 0.03). Limitations include a retrospective, single-center analysis. Conclusions and clinical implications: Despite the SP approach in RARP resulting in fewer retrieved lymph nodes, outcomes were comparable with the MP approach regarding the detection of patients with positive lymph nodes and the number of positive nodes. Additionally, the SP approach led to lower pain levels and shorter hospital stays. Patient summary: With this study, we demonstrate that pelvic lymph node dissection performed via the extraperitoneal approach during robotic-assisted radical prostatectomy with a single-port system provides comparable outcomes with the standard transperitoneal multiport approach in detecting patients with positive lymph nodes and retrieving positive nodes. In addition, it offers significantly reduced pain levels and shorter hospital stays.
RESUMO
INTRODUCTION: Studies comparing radical prostatectomy (RP) to radiation therapy (RT) have consistently shown that patients undergoing RT have a higher risk of other-cause mortality (OCM) compared to RP, signifying poor health status of the former patients. We aimed to evaluate the impact of RP versus RT on cancer-specific mortality (CSM) over a cohort with equivalent OCM risk. PATIENTS AND METHODS: The SEER database was queried to identify patients with nonmetastatic PCa between 2004 and 2009. Patients were matched based on their calculated 10-year OCM risk and further stratified for D'Amico Risk Score and Gleason Grade. A Cox-regression model was used to calculate the 10-year OCM risk. Propensity-score based on the calculated OCM risk were used to match RP and RT patients. Cumulative incidence curves and Competing-risk regression analyses were used to examine the impact of treatment on CSM in the matched cohort. RESULTS: We identified 55,106 PCa patients treated with RP and 36,674 treated with RT. After match, 6,506 patients were equally distributed for RT versus RP, with no difference in OCM rates (P = .2). The 10-year CSM rates were 8.8% versus 0.6% (P = .01) for RT versus RP in patients with unfavorable-intermediate-risk (Gleason Score 4 + 3) and 7.9% versus 3.9% (P = .003) for high-risk disease. There was no difference in CSM among RT and RP patients for favorable-intermediate-risk (Gleason Score 3 + 4) and low-risk disease. CONCLUSIONS: In a matched cohort of PCa patients with comparable OCM between the 2 arms, RP yielded a more favorable CSM rate compared to RT only for unfavorable-intermediate- and high-risk groups.
RESUMO
OBJECTIVE: Comparative effectiveness studies comparing trimodal therapy (TMT) to radical cystectomy (RC) are typically hindered by selection bias where TMT is usually reserved to patients with poor overall health status. We developed a novel approach by matching patients based on their calculated other-cause mortality (OCM) risk. Using this homogeneous cohort, we tested the impact of TMT vs RC on cancer-specific mortality (CSM). MATERIALS AND METHODS: The Surveillance, Epidemiology and End Results (SEER) 2004-2018 database was queried to identify patients diagnosed with cT2-4N0M0 muscle-invasive bladder cancer (MIBC). A Fine-Gray competing-risk regression model calculating the 5-year OCM risk was used to create a 1:1 propensity-score matched-cohort of patients treated with RC or TMT. Cumulative incidence and competing-risk regression analyses tested the impact of treatment type (RC vs TMT) on CSM. Patients were further stratified according to clinical T stage (cT2 vs cT3-4) in sensitivity analyses. RESULTS: We identified 6,587 patients (76%) treated with RC and 2,057 (24%) with TMT. The median follow-up was 3.0 years. In the unmatched-cohort, 5-year OCM and CSM rates were 14% and 40% for RC vs 23% and 47% in TMT group, respectively (all P < 0.001). Our matched-cohort included 4,074 patients, equally distributed for treatment type, with no difference in 5-year OCM (HR: 0.98, 95% CI: 0.86-1.11, Pâ¯=â¯0.714). In clinical-stage specific sensitivity analyses, 5-year CSM rate was significantly worse for cT2N0M0 patients treated with TMT (HR: 1.52, 95% CI: 1.21-1.91, P < 0.001) than those treated with RC. For cT3-4N0M0 patients, there was no difference in CSM among the 2 approaches (HR: 0.98, 95% CI: 0.63-1.52, Pâ¯=â¯0.900). CONCLUSIONS: Our findings demonstrate an oncologic advantage of RC over TMT for cT2 MIBC patients. Conversely, we did not find a cancer-specific survival difference for cT3-T4 MIBC patients, regardless of treatment.
RESUMO
PURPOSE: To evaluate the activity and safety of nivolumab with nab-paclitaxel as neoadjuvant therapy, followed by radical cystectomy (RC) and postsurgical adjuvant nivolumab in patients with muscle-invasive bladder cancer (MIBC). PATIENTS AND METHODS: Eligible patients had an Eastern Cooperative Oncology Group performance status of ≤1 and a T2-4aN0-1M0 stage with >50% urothelial carcinoma histology and were ineligible for or refused cisplatin-based chemotherapy. Patients received four cycles of nivolumab 360 mg once every 3 weeks + nab-paclitaxel 125 mg/m2 once on days 1 and 8, every 3 weeks, followed by RC, and then adjuvant nivolumab 360 mg once every 3 weeks × 13 cycles. The primary end point was the pathologic complete response (CR) rate (ypT0N0). Secondary end points were major pathologic response (ypT≤1N0), safety, event-free survival (EFS), and overall survival. RESULTS: Thirty-one patients were enrolled from December 2021 to June 2023; 19 (61.3%) had a cT2 stage, two (6.5%) had N1 stage, and 16 (51.6%) had a variant histology. Five patients (16.1%) received less than four full courses of neoadjuvant treatment because of treatment-related adverse events (TRAEs). Grade 3/4 TRAEs occurred in eight patients (25.8%). Twenty-eight patients underwent RC, and three refused RC after evidence of clinical CR and received a redo transurethral resection of the bladder tumor (reTURBT). The trial met its primary end point: 10 patients (32.3%; 95% CI, 16.7 to 51.4) achieved an ypT0N0 response. By including those who underwent reTURBT, 22 (70.9%; 95% CI, 55 to 87) achieved an ypT≤1N0-x response. After a median follow-up of 12 months (range, 5-22), two patients had a disease relapse after surgery. The 12-month EFS was 89.8% (95% CI, 79.5 to 100). CONCLUSION: To our knowledge, the first results from NURE-Combo trial suggest that this combination could expand the therapeutic opportunities of immune-chemotherapy in patients with MIBC.
RESUMO
INTRODUCTION: Leukemia history affects some radical prostatectomy (RP) patients. Although its prevalence and effect as an adverse risk factor are well known in cardiac surgery, the number of RP patients with a leukemia history, as well as their rate of adverse in-hospital outcomes, are unknown. METHODS: We identified RP patients (National Inpatient Sample 2000-2019), stratified according to the presence or absence of a leukemia history. Descriptive analyses, propensity score matching (PSM, ratio 1:10), and multivariable logistic regression models were used. RESULTS: Of 259,939 RP patients, 416 (0.2%) had a leukemia history. Their proportion increased from 0.1 to 0.2% covering the study span (p < 0.01). Leukemia history patients were older (median age, 64 vs. 62 years, p < 0.001). After PSM for age, insurance status, ethnicity, pelvic lymph node dissection, and Charlson Comorbidity Index, leukemia history RP patients exhibited higher rates of acute kidney injury (<2.6 vs. 0.9%; Odds Ratio [OR] 2.0, p = 0.02), more frequently underwent dialysis (3.6 vs. 1.9%; OR 1.9, p = 0.03), and more frequently had a length of stay exceeding one week (4.8 vs. 2.5%; OR 2.0, p = 0.006). CONCLUSIONS: Although leukemia history RP patients are rare, their numbers have increased. Renal complications and extended hospital stays are more frequent in those individuals.
RESUMO
PURPOSE: To quantify to what extent the 5-year overall survival (OS) of adrenocortical carcinoma (ACC) patients differs from age- and sex-matched population-based controls, especially when stage is considered. METHODS: We relied on the Surveillance, Epidemiology, and End Results database (2004-2020) to identify newly diagnosed (2004-2014) ACC patients. Subsequently, we compared OS between ACC patients relative to simulated age- and sex-matched controls (Monte Carlo simulation), according to Social Security Administration Life Tables (2004-2020). RESULTS: Of all 742 ACC patients, 301 (41%) harbored localized stage, 173 (23%) locally advanced stage, and 268 (36%) metastatic stage. At 5-years follow-up, ACC patients' OS was 33%. After stratification for stage, the 5-years OS was 55 vs. 31 vs. 8% in localized, locally advanced, and metastatic stages, respectively. Conversely, after Monte Carlo simulation of age- and sex-matched controls, OS at five-years was 93% in the entire simulated cohort vs. 94% in the simulated localized cohort vs. 92 and 92% in locally advanced and metastatic stage, respectively. The resulting differences in OS between ACC patients and age- and sex-matched population-based controls were 60 vs. 39 vs. 61 vs. 84% respectively in the overall cohort vs. localized vs. locally advanced vs. metastatic stage. CONCLUSION: The most pronounced life expectancy detriment (84%) was recorded in metastatic ACC followed by locally advanced ACC patients (61%). Unfortunately, even in patients with localized ACC, life expectancy was 39% lower than that of the general population. Therefore, regardless of stage, ACC diagnosis results in a very pronounced detriment in life expectancy relative to the general population.
RESUMO
BACKGROUND AND OBJECTIVE: The benefits of the detection of clinically significant prostate cancer (csPCa) and safety of magnetic resonance imaging (MRI)-targeted transperineal (TP) prostate biopsy (TP-Tbx) versus transrectal (TR) approaches are still a matter of debate. This review aims to compare the efficacy and safety of TP-Tbx and MRI-targeted TR biopsy (TR-Tbx). METHODS: A systematic literature search was performed in PubMed/Medline, Scopus, and Web of Science to identify records of prospective randomized controlled trials (RCTs) comparing TP-Tbx and TR-Tbx published until May 2024. The primary outcomes included detection rates of csPCa (International Society of Urological Pathology [ISUP] ≥2) and rates of complications. KEY FINDINGS AND LIMITATIONS: Three RCTs (PREVENT, ProBE-PC, and PERFECT) met the inclusion criteria. The TR technique was commonly administered with antibiotic prophylaxis to mitigate infection risks or after a rectal swab. No difference was found between TP-Tbx and TR-Tbx in terms of either csPCa (odds ratio [OR] 0.9, 95% confidence interval [CI]: 0.7-1.1) or ISUP 1 prostate cancer (PCa; OR 1.1, 95% CI: 0.8-1.4) detection. Postprocedural infection (OR 0.8, 95% CI: 0.4-1.8), sepsis (OR 0.6, 95% CI: 0.1-4.5), and urinary retention rates (OR 0.5, 95% CI: 0.1-1.6) were similar. Pain during the TP approach was slightly higher than during the TR approach, but after 7 d of follow-up, the differences between the two approaches were minimal. Variations in biopsy numbers per patient, patient selection, use of 5-alpha reductase inhibitors, needle sizes, TP techniques, and pain scores (reported in only one RCT), along with the multicenter nature of RCTs, limit the study. CONCLUSIONS AND CLINICAL IMPLICATIONS: TP-Tbx and TR-Tbx show similar results in detecting PCa, with comparable rates of infections, urinary retention, and effectiveness in managing biopsy-associated pain. TP-Tbx can safely omit antibiotics without increasing infection risk, unlike TR-Tbx. The tendency to exclude from practice TR-Tbx with prophylactic antibiotics due to infection concerns could be moderated; however, the directionality of some key outcomes, as infections and sepsis, favor the TP approach despite a lack of statistical significance. PATIENT SUMMARY: There were no significant differences in the prostate biopsy approaches (transperineal [TP] vs transrectal [TR]) for prostate cancer detection and complications. However, the MRI-targeted TP prostate biopsy approach may be advantageous as it can be performed safely without antibiotics, potentially reducing antibiotic resistance.
RESUMO
Objectives: This study aimed to test the association between of type and number of D'Amico high-risk criteria (DHRCs) with cancer-specific mortality (CSM) in high-risk prostate cancer patients treated with radical prostatectomy. Materials and methods: In the Surveillance, Epidemiology, and End Results database (2004-2016), we identified 31,281 radical prostatectomy patients with at least 1 DHRC, namely, prostate-specific antigen (PSA) >20 ng/mL (hrPSA), biopsy Gleason Grade Group (hrGGG) score of 4 and 5, or clinical tumor stage ≥T3 (hrcT). Multivariable Cox regression models and competing risks regression models (adjusting for other cause mortality) tested the association between DHRCs and 5-year CSM. Results: Of 31,281 patients, 14,394 (67%) exclusively harbored hrGGG, 3189 (15%) harbored hrPSA, and 1781 (8.2%) harbored hrcT. Only 2132 patients (6.8%) harbored a combination of the 2 DHRCs, and 138 (0.6%) had all 3 DHRCs. Five-year CSM rates ranged from 0.9% to 3.0% when any individual DHRC was present (hrcT, hrPSA, and hrGGG, in that order), 1.6% to 5.9% when 2 DHRCs were present (hrPSA-hrcT, hrcT-hrGGG, and hrPSA-hrGGG, in that order), and 8.1% when all 3 DHRCs were present. Cox regression models and competing risks regression confirmed the independent predictor status of DHRCs for 5-year CSM that was observed in univariable analyses, with hazard ratios from 1.00 to 2.83 for 1 DHRC, 2.35 to 5.88 for combinations of 2 DHRCs, and 7.13 for all 3 DHRCs. Conclusions: Within individual DHRCs, hrcT and hrPSA exhibited weaker effects than hrGGG did. Moreover, a dose-response effect was identified according to the number of DHRCs. Accordingly, the type and number of DHRCs allow further risk stratification within the high-risk subgroup.
RESUMO
PURPOSE: It is unknown to what extent 10-year overall survival of radical nephrectomy treated intermediate/high-risk non-metastatic clear cell renal carcinoma patients differs from age- and sex-matched population-based controls, especially when race/ethnicity is considered (Caucasian vs. African American vs. Hispanic vs. Asian/Pacific Islander). METHODS: We relied on the SEER database (2004-2018) to identify newly diagnosed radical nephrectomy treated intermediate/high risk non-metastatic clear cell renal carcinoma patients. For each case, we simulated an age- and sex-matched control relying on Social Security Administration Life Tables with 10 years of follow-up. We compared overall survival between renal carcinoma cases and population-based controls. Multivariable competing risks regression models tested for predictors of cancer-specific mortality versus other-cause mortality. RESULTS: Of 6877 radical nephrectomy treated intermediate/high risk non-metastatic clear cell renal carcinoma patients, 5050 (73%) were Caucasian versus 433 (6%) African American versus 1002 (15%) Hispanic versus 392 (6%) Asian/Pacific Islanders. At 10 years, overall survival difference between radical nephrectomy treated intermediate/high risk non-metastatic clear cell renal carcinoma patients versus population-based controls was greatest in African Americans (51% vs. 81%, Δ = 30%), followed by Hispanics (54% vs. 80%, Δ = 26%), Asian/Pacific Islanders (56% vs. 80%, Δ = 24%) and Caucasians (52% vs. 74%, Δ = 22%). In competing risks regression, only African Americans exhibited significantly higher other cause mortality (hazard ratio = 1.3; 95% confidence interval = 1.1 - 1.6; p = 0.01) than others. CONCLUSION: Relative to Life Tables' derived sex- and age-matched controls, radical nephrectomy treated intermediate/high-risk non-metastatic clear cell renal carcinoma patients exhibit worse overall survival, with worst overall survival recorded in African Americans of all race/ethnicity groups.
RESUMO
INTRODUCTION: It is unknown whether race/ethnicity affects access and/or survival after neoadjuvant (NAC) or adjuvant chemotherapy (ADJ) at radical cystectomy (RC). We addressed these knowledge gaps. MATERIAL AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2007-2020), we identified NAC candidates (T2-T4N0M0) and ADJ candidates (T3-T4 and/or N1-3). We focused on the four most prevalent race/ethnicities: Caucasians, Hispanics, African American (AA), and Asian/Pacific Islanders (API). Multivariable logistic regression models (MLR) tested access to NAC and ADJ. Subsequently, within NAC-exposed patients, survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression models addressed CSM according to race/ethnicity were fitted. We repeated the same methodology in ADJ-exposed patients. RESULTS: In 6418 NAC candidates, NAC was administered in 1011 (19.0%) Caucasians, 88 (21.0%) Hispanics, 65 (17.0%) AA, and 53 (18.0%) API. In MLR, AA exhibited lower access rates to NAC (OR 0.83, p = 0.04). In NAC-exposed patients, AA independently predicted higher CSM (HR 1.3, p < 0.001) and API independently predicted lower CSM (HR 0.83, p = 0.03). Similarly, in 5195 ADJ candidates, ADJ was administered to 1387 (33.0%) Caucasians, 100 (28.0%) Hispanics, 105 (29.0%) AA, and 90 (37.0%) API. In MLR, AA (OR 68, p = 0.003) and Hispanics (OR 0.69, p = 0.004) exhibited lower access rates to ADJ. In ADJ-exposed patients, AA independently predicted lower CSM (HR 1.32, p < 0.001), while API showed better CSM (HR 0.82, p = 0.01). CONCLUSION: Relative to Caucasians, AA are less likely to receive either NAC or ADJ. Moreover, relative to Caucasians, AA exhibit higher CSM even when treated with either NAC or ADJ.
RESUMO
CONTEXT: Although complete surgical resection provides the only means of cure in adrenocortical carcinoma (ACC), the magnitude of the survival benefit of adrenalectomy in metastatic ACC (mACC) is unknown. OBJECTIVE: To assess the effect of adrenalectomy on survival outcomes in patients with mACC in a real-world setting. DESIGN AND SETTING: Patients with mACC were identified within the Surveillance, Epidemiology, and End Results database (SEER 2004-2020) and we tested for differences according to adrenalectomy status. PATIENTS: Patients aged ≥18 years with metastatic ACC at initial presentation who were treated between 2004-2020. INTERVENTION: Primary tumor resection status (Adrenalectomy vs no-adrenalectomy). MAIN OUTCOME AND MEASURES: Kaplan-Meier plots, multivariable Cox regression models and landmark analyses were used. Sensitivity analyses focused on use of systemic therapy, contemporary (2012-2020) vs. historical (2004-2011), single vs. multiple metastatic sites and assessable specific solitary metastatic sites (lung only and liver only). RESULTS: Of 543 patients with mACC, 194 (36%) underwent adrenalectomy. In multivariable analyses, adrenalectomy was associated with lower overall mortality without (hazard ratio [HR]: 0.39; p<0.001), as well as with three months' landmark analyses (HR: 0.57, p=0.002). The same association effect with three months' landmark analyses was recorded in patients exposed to systemic therapy (HR: 0.49, p<0.001), contemporary patients (HR: 0.57, p=0.004), historical patients (HR: 0.42 , p<0.001), and in those with lung only solitary metastasis (HR: 0.50, p=0.02). In contrast, no significant association was recorded in patients naïve to systemic therapy (HR: 0.68, p=0.3), those with multiple metastatic sites (HR: 0.55, p=0.07) and those with liver only solitary metastasis (HR: 0.98, p=0.9). CONCLUSIONS: The current results indicate a potential protective effect of adrenalectomy in mACC, particularly in patients exposed to systemic therapy and those with lung-only metastases.
RESUMO
The use of 3-dimensional (3D) technology has become increasingly popular across different surgical specialities to improve surgical outcomes. 3D technology has the potential to be applied to robotic assisted radical prostatectomy to visualise the patient's prostate anatomy to be used as a preoperative and peri operative surgical guide. This literature review aims to analyse all relevant pre-existing research on this topic. Following PRISMA guidelines, a search was carried out on PubMed, Medline, and Scopus. A total of seven studies were included in this literature review; two of which used printed-3D models and the remaining five using virtual augmented reality (AR) 3D models. Results displayed variation with select studies presenting that the use of 3D models enhances surgical outcomes and reduces complications whilst others displayed conflicting evidence. The use of 3D modelling within surgery has potential to improve various areas. This includes the potential surgical outcomes, including complication rates, due to improved planning and education.

OBJECTIVE: Systemic therapy is guideline-recommended for metastatic urothelial carcinoma of the urinary bladder (UCUB). Unmarried status represents an important barrier to treatment access in many primaries. The importance of married status is unknown in the context of systemic therapy in metastatic UCUB and was addressed in the current study. METHODS: We relied on the Surveillance, Epidemiology, and End Results database (2004-2020) to identify patients with metastatic UCUB. Univariable and multivariable logistic regression models were fitted to address systemic therapy rates. Additionally, temporal trends were plotted. RESULTS: Overall, 6873 patients with stage IV UCUB were identified. Of those, 4853 (71%) were male. Of males, 2993 (62%) were married vs. 797 (39%) of females. The rates of systemic therapy were 55% in both married males and married females. Married males and females differed from their unmarried counterparts regarding age and race/ethnicity. In males, prior to any adjustment, married status was associated with an odds ratio of 1.46 (P < .001). After adjustment for age and race/ethnicity, the odds ratio increased to 1.73 (P < .001). In females, prior to any adjustment, married status was associated with an odds ratio of 1.94 (P < .001). After adjustment for age and race/ethnicity, the odds ratio decreased to 1.57 (P < .001). CONCLUSION: Unmarried males and unmarried females are significantly exposed to lower access to systemic therapy compared to their married counterparts. In consequence, both unmarried men and unmarried women should be given very careful consideration when use of systemic therapy in metastatic UCUB is contemplated.
RESUMO
PURPOSE: We investigated regional differences in patients with stage III nonseminoma germ cell tumor (NSGCT). Specifically, we investigated differences in baseline patient, tumor characteristics and treatment characteristics, as well as cancer-specific mortality (CSM) across different regions of the United States. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) database (2004-2018), patient (age, race/ethnicity), tumor (International Germ Cell Cancer Collaborative Group [IGCCCG] prognostic groups) and treatment (systemic therapy and retroperitoneal lymph dissection [RPLND] status) characteristics were tabulated for stage III NSGCT patients, according to 12 SEER registries representing different geographic regions. Multinomial regression models and multivariable Cox regression models testing for cancer-specific mortality (CSM) were used. RESULTS: In 3,174 stage III NSGCT patients, registry-specific patient counts ranged from 51 (1.5%) to 1630 (51.3%). Differences across registries existed for age (12%-31% for age 40+), race/ethnicity (5%-73% for others than non-Hispanic whites), IGCCCG prognostic groups (24%-43% vs. 14-24% vs. 3%-20%, in respectively poor vs. intermediate vs. good prognosis), systemic therapy (87%-96%) and RPLND status (12%-35%). After adjustment, clinically meaningful inter-registry differences remained for systemic therapy (84%-97%) and RPLND (11%-32%). Unadjusted 5-year CSM rates ranged from 7.1% to 23.3%. Finally in multivariable analyses addressing CSM, 2 registries exhibited more favorable outcomes than SEER registry of reference (SEER Registry 12): SEER Registry 4 (Hazard Ratio (HR): 0.36) and SEER Registry 9 (HR: 0.64; both P = .004). CONCLUSION: We identified important regional differences in patient, tumor and treatment characteristics, as well as CSM which may be indicative of regional differences in quality of care or expertise in stage III NGSCT management.
RESUMO
BACKGROUND: To assess cancer-specific mortality (CSM) and other-cause mortality (OCM) rates in patients with rare histological prostate cancer subtypes. METHODS: Using the Surveillance, Epidemiology, and End Results database (2004-2020), we applied smoothed cumulative incidence plots and competing risks regression (CRR) models. RESULTS: Of 827,549 patients, 1510 (0.18%) harbored ductal, 952 (0.12%) neuroendocrine, 462 (0.06%) mucinous, and 95 (0.01%) signet ring cell carcinoma. In the localized stage, five-year CSM vs. OCM rates ranged from 2 vs. 10% in acinar and 3 vs. 8% in mucinous, to 55 vs. 19% in neuroendocrine carcinoma patients. In the locally advanced stage, five-year CSM vs. OCM rates ranged from 5 vs. 6% in acinar, to 14 vs. 16% in ductal, and to 71 vs. 15% in neuroendocrine carcinoma patients. In the metastatic stage, five-year CSM vs. OCM rates ranged from 49 vs. 15% in signet ring cell and 56 vs. 16% in mucinous, to 63 vs. 9% in ductal and 85 vs. 12% in neuroendocrine carcinoma. In multivariable CRR, localized neuroendocrine (HR 3.09), locally advanced neuroendocrine (HR 9.66), locally advanced ductal (HR 2.26), and finally metastatic neuroendocrine carcinoma patients (HR 3.57; all p < 0.001) exhibited higher CSM rates relative to acinar adenocarcinoma patients. CONCLUSIONS: Compared to acinar adenocarcinoma, patients with neuroendocrine carcinoma of all stages and locally advanced ductal carcinoma exhibit higher CSM rates. Conversely, CSM rates of mucinous and signet ring cell adenocarcinoma do not differ from those of acinar adenocarcinoma.
