RESUMEN

PURPOSE: To compare cancer-specific mortality (CSM) and overall mortality (OM) between immediate radical cystectomy (RC) and Bacillus Calmette-Guérin (BCG) immunotherapy for T1 squamous bladder cancer (BCa). METHODS: We retrospectively analysed 188 T1 high-grade squamous BCa patients treated between 1998 and 2019 at fifteen tertiary referral centres. Median follow-up time was 36 months (interquartile range: 19-76). The cumulative incidence and Kaplan-Meier curves were applied for CSM and OM, respectively, and compared with the Pepe-Mori and log-rank tests. Multivariable Cox models, adjusted for pathological findings at initial transurethral resection of bladder (TURB) specimen, were adopted to predict tumour recurrence and tumour progression after BCG immunotherapy. RESULTS: Immediate RC and conservative management were performed in 20% and 80% of patients, respectively. 5-year CSM and OM did not significantly differ between the two therapeutic strategies (Pepe-Mori test p = 0.052 and log-rank test p = 0.2, respectively). At multivariable Cox analyses, pure squamous cell carcinoma (SqCC) was an independent predictor of tumour progression (p = 0.04), while concomitant lympho-vascular invasion (LVI) was an independent predictor of both tumour recurrence and progression (p = 0.04) after BCG. Patients with neither pure SqCC nor LVI showed a significant benefit in 3-year recurrence-free survival and progression-free survival compared to individuals with pure SqCC or LVI (60% vs. 44%, p = 0.04 and 80% vs. 68%, p = 0.004, respectively). CONCLUSION: BCG could represent an effective treatment for T1 squamous BCa patients with neither pure SqCC nor LVI, while immediate RC should be preferred among T1 squamous BCa patients with pure SqCC or LVI at initial TURB specimen.

RESUMEN

OBJECTIVE: To examine the rates of adherence to guidelines for pelvic lymph node dissection (PLND) in patients treated with radical cystectomy (RC) and to identify predictors of omitting PLND. MATERIALS AND METHODS: We relied on 66,208 patients treated with RC between 2004 and 2013 within the National Inpatients Sample (NIS) database. We examined the rates of PLND according to year of surgery, patient and hospital characteristics. Univariate and multivariate logistic regression analyses assessed the probability of PLND use, after adjusting for year of surgery, age, gender, race, comorbidities, hospital location, teaching status and hospital surgical volume. RESULTS: Overall, PLND was performed on 54,223 (81.9%) RC patients. The rates PLND at RC significantly increased over the study period from 72.3% in 2004 to 85.9% in 2013, (p < 0.001). Barriers to PLND at RC consisted of female gender (OR: 1.31; 95% CI 1.25-1.38; p < 0.001), African American race (OR: 1.21; 95% CI 1.10-1.32; p < 0.001), intermediate (OR: 1.78; 95% CI 1.68-1.88; p < 0.001) or low surgical volume institutions (OR: 2.59; 95% CI 2.44-2.74; p < 0.001), non-teaching institution status (OR: 1.21; 95% CI 1.15-1.27; p < 0.001) and rural hospital location (OR: 1.13; 95% CI 1.01-1.25; p = 0.03). CONCLUSIONS: It is encouraging to note increasing rates of PLND at RC over time. Both patients and hospital characteristics influence PLND rates. More efforts should be aimed at reducing inequalities in PLND at RC due to these highly modifiable variables.

RESUMEN

BACKGROUND: Literature lacks clear evidence regarding the optimal treatment for non-muscle-invasive micropapillary bladder cancer (MPBC) due to its rarity and the presence of only small sample size and single-centre studies. OBJECTIVE: To assess cancer-specific mortality (CSM) and overall mortality (OM) between immediate radical cystectomy (RC) and conservative management among T1 high-grade (HG) MPBC. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively analysed a multicentre dataset including 119 T1 HG MPBC patients treated between 2005 and 2019 at 15 tertiary referral centres. The median follow-up time was 35 mo (interquartile range: 19-64). INTERVENTION: Patients underwent immediate RC versus conservative management with bacillus Calmette-Guérin. OUTCOMES MEASUREMENTS AND STATISTICAL ANALYSIS: Cumulative incidence functions and Kaplan-Meier methods were applied to estimate survival outcomes. Multivariable Cox analyses were performed to assess independent predictors of disease recurrence and disease progression after conservative management; covariates consisted of pure MPBC, concomitant lymphovascular invasion (LVI), and carcinoma in situ at initial diagnosis. RESULTS AND LIMITATIONS: Immediate RC and conservative management were performed in 27% and 73% of patients, respectively. CSM and OM did not differ significantly among patient treated with immediate RC versus conservative management (Pepe-Mori test p = 0.5 and log-rank test p = 0.9, respectively). Overall, 66.7% and 34.5% of patients experienced disease recurrence and disease progression after conservative management, respectively. At multivariable Cox analyses, concomitant LVI was an independent predictor of disease recurrence (p = 0.01) and progression (p = 0.03), while pure MPBC was independently associated with disease progression (p = 0.03). The absence of a centralised re-review and the retrospective design represent the main limitations of our study. CONCLUSIONS: Conservative management could achieve satisfactory results among T1 HG MPBC patients with neither pure MPBC nor LVI at initial diagnosis. PATIENT SUMMARY: Bacillus Calmette-Guérin seems to be an effective therapy for T1 micropapillary bladder cancer patients with neither pure micropapillary disease nor lymphovascular invasion at initial diagnosis.

RESUMEN

INTRODUCTION: We sought to evaluate population-based costs variations and predictors of outlier costs for percutaneous nephrolithotomy (PCNL) in the U.S. METHODS: Using the Premier Healthcare Database, we identified all patients diagnosed with kidney/ureter calculus who underwent PCNL from 2003-2015. We evaluated 90-day direct hospital costs, defining high- and low-cost surgery as those >90th and <10th percentile, respectively. We constructed a multilevel, hierarchical regression model and calculated the pseudo-R2 of each variable, which translates to the percentage variability contributed by that variable on 90-day direct hospital costs. RESULTS: A total of 114 581 patients underwent PCNL during the 12-year study period. Mean cost in the low-cost group was $5787 (95% confidence interval [CI] 5716-5856) vs. $38 590(95% CI 37 357-39 923) in the high-cost group. Cost variations were substantially impacted by patient (63.7%) and surgical (18.5%) characteristics and less so by hospital characteristics (3.9%). Significant predictors of high costs included more comorbidities (≥2 vs. 0: odds ratio [OR] 1.81; p=0.01) and hospital region (Northeast vs. Midwest: OR 2.04; p=0.03). Predictors of low cost were hospital bed size of 300-499 beds (OR 1.35; p<0.01) and urban hospitals (OR 2.77; p=0.01). Factors less likely to be associated with low-cost PCNL were more comorbidities (Charlson Comorbidity Index [CCI] ≥2: OR 0.69; p<0.0001), larger hospitals (OR 0.61; p=0.01), and teaching hospitals (OR 0.33; p<0.0001). CONCLUSIONS: Our contemporary analysis demonstrates that patient and surgical characteristics had a significant effect on costs associated with PCNL. Poor comorbidity status contributed to high costs, highlighting the importance of patient selection.

RESUMEN

INTRODUCTION: The absolute and proportional numbers of elderly patients diagnosed with localized prostate cancer (PCa) are on the rise. We examined treatment trends and reimbursement figures in localized PCa patients aged ≥80 years. METHODS: Between 2000 and 2008, we identified 30 217 localized PCa patients aged ≥80 years in Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked database. Alternative treatment modalities consisted of conservative management (CM), radiation therapy (RT), radical prostatectomy (RP), and primary androgen-deprivation therapy (PADT). For all four modalities, utilization and reimbursements were examined. RESULTS: PADT was the most frequently used treatment modality between 2000 and 2005. CM became the dominant treatment modality from 2006-2008. RP rates were marginal. RT ranked third, and its annual rate increased from 20.77% in 2000 to 29.13% in 2008. Median individual reimbursement of RT was highest and ranged from $29 343 in 2000 to $31 090 in 2008, followed by RP (from $20 560 in 2000 to $19 580 in 2008), PADT (from $18 901 in 2000 to $8000 in 2008), and CM (from $1824 in 2000 to $1938 in 2008). RT contributed to most of the cumulative annual reimbursements from 2003 (49.24%) to 2008 (72.97%). PADT ranked first from 2000 (54.56%) to 2002 (50.49%), but decreased by 19.40% in 2008. CM's contribution increased from 4.42% in 2000 to 6.96% in 2008. RP's share of reimbursements was stable during the study period. CONCLUSIONS: Our results, focusing on localized PCa treatment in patients aged ≥80 years, showed an important increase in rates, median cost, and proportion of cumulative cost related to RT.

RESUMEN

We performed a systematic review of all cases of Fournier's Gangrene (FG) at our hospital over a 12-year period. A total of 26 cases were assessed. Our goal was to determine the mortality rate and to identify risk factors associated with FG. We also wanted to examine three potential prognostic factors in relation to patient survival, including the time delay from emergency room admission to surgery, the initial extent of the disease, and the impact of more than one debridement procedure under general anesthesia. The time between emergency room admission and the beginning of surgical debridement was not statistically different between survivors and non-survivors. The extent of surgical debridement was close to the margin of statistical significance (p = 0.07) and can be considered an index of the extent of the disease. FG extending to the thighs or to the abdominal wall carries a worse prognosis. The number of surgical debridement procedures done under anesthesia was statistically different between survivors and non-survivors. Patients were 4.8 times more at risk of dying if they are required to have more than one surgical debridement under general anesthesia. This presumably reflects persistent gangrene following initial surgical debridement, fluid resuscitation, and wide spectrum antibiotic treatment.

RESUMEN

The challenges of transition from the pediatric to the adult setting have been reported. We describe a case of massive stone burden in the ileocecal pouch of a patient lost to follow-up after his transfer from a pediatric to an adult institution. Although we successfully managed the patient and retrieved the pouch stones without any complications, several surgical complications may occur in a patient with a history of extensive abdominal surgery and bladder exstrophy. This patient's late complication might have been prevented with a more efficient transfer from a pediatric to an adult institution.
