Symptomatic and functional recovery after transurethral resection of bladder tumor: Data from ecological momentary symptom assessment.

OBJECTIVES: To quantitatively describe the nature, severity, and duration of symptoms and functional impairment during recovery from transurethral resection of bladder tumors. MATERIALS AND METHODS: All patients scheduled for transurethral resection were approached for enrollment in a text-message based ecological momentary symptom assessment platform. Nine patients reported outcomes were measured 7 days before surgery and on postoperative days 1, 2, 3, 5, 7, 10, and 14 using a 5-point Likert scale. Self-reported degree of hematuria was collected using a visual scale. Clinical data was collected via retrospective chart review. RESULTS: A total of 159 patients were analyzed. Postoperative symptoms were overall mild, with the largest differences from baseline to postoperative day 1 seen in dysuria (median 0/5 vs. 3/5) and ability to work (median 5/5 vs. 4/5). Recovery was generally rapid, with 76% of patients reporting ≥4/5 agreement with the statement "I feel recovered from surgery" by postoperative day 2, although 15% of patients reported persistently lower levels of agreement on postoperative day 10 or 14. Patients undergoing larger resections (≥2cm) did take longer to return to baseline in multiple symptom domains, but the difference of medians vs. those undergoing smaller resections was less than 1 day across all domains. Multivariable analysis suggested that receiving perioperative intravesical chemotherapy was associated with longer time to recovery. 84% of patients reported clear yellow urine by postoperative day 3. CONCLUSION: In this population, hematuria and negative effects on quality of life resulting from transurethral resection of bladder tumors were generally mild and short-lived, although a small number of patients experienced longer recoveries.

The Implication of Preoperative Central Stenosis on Patient-Reported Outcomes After Lumbar Decompression Surgery.

OBJECTIVE: To assess the impact of central stenosis severity on patient-reported outcomes after lumbar decompression. METHODS: Patient diagnosis, demographics, and surgical characteristics were collected via query search and manual chart review of electronic medical records. The inclusion criteria were posterior lumbar decompressions from 2014-2020, with accessible magnetic resonance imaging reports. As previously validated by Lee et al., central stenosis was determined on magnetic resonance imaging and graded as none, mild, moderate, or severe. Patients were dichotomized into 2 groups to improve statistical power for comparisons: none or mild central stenosis and moderate or severe central stenosis. Patient-reported outcome measures (PROMs) were compared between cohorts at 1 year postoperatively. Statistical significance was set at P < 0.05. RESULTS: On bivariate analysis, no significant differences were noted between cohorts with regard to preoperative, 1-year postoperative, and delta PROMs. In addition, no significant difference in the number of patients attaining minimal clinically important difference (MCID) for each PROM was noted between cohorts. With the exception of mental score of the Short Form-12 survey, all intragroup preoperative to postoperative PROMs indicated significant improvement (all P < 0.05) after lumbar decompression surgery. Multivariate regression identified moderate or severe central canal stenosis as a significant independent predictor of improvement in visual analog scale back (estimate = -1.464, P = 0.045). CONCLUSIONS: We demonstrate that patients with moderate or severe central spinal stenosis may have more improvement in back pain than those with mild or no central stenosis after lumbar spine decompression surgery.

Cystoscopy and Systematic Bladder Tissue Sampling in Predicting pT0 Bladder Cancer: A Prospective Trial.

PURPOSE: Concern for discordance between clinical staging and final pathology drives current management of patients deemed appropriate candidates for radical cystectomy. Therefore, we set out to prospectively investigate reliability and shortcomings of cystoscopic evaluation in radical cystectomy candidates. MATERIALS AND METHODS: Patients undergoing radical cystectomy for urothelial carcinoma were enrolled in a prospective single-arm study to evaluate reliability of Systematic Endoscopic Evaluation in predicting pT0 urothelial carcinoma (NCT02968732). Systematic Endoscopic Evaluation consisted of cystoscopy and tissue sampling at the time of radical cystectomy. Systematic Endoscopic Evaluation results were compared to radical cystectomy pathology. The primary end point was the negative predictive value of Systematic Endoscopic Evaluation findings in predicting radical cystectomy pathology. RESULTS: A total of 61 patients underwent Systematic Endoscopic Evaluation and radical cystectomy. Indications included muscle invasive bladder cancer in 42 (68.9%) and high risk nonmuscle invasive bladder cancer in 19 (31.1%). In all, 38 (62.3%, 90.5% of patients with muscle invasive bladder cancer) received neoadjuvant chemotherapy. On Systematic Endoscopic Evaluation, 31 (50.8%) patients demonstrated no visual nor biopsy-based evidence of disease (seeT0), yet 16/31 (51.6%) harbored residual disease (>pT0), including 8 (8/31, 25.8%) with residual ≥pT2 disease upon radical cystectomy. The negative predictive value of Systematic Endoscopic Evaluation predicting a pT0 bladder was 48.4% (CI 30.2-66.9), which was below our prespecified hypothesis. Therefore, the trial was stopped for futility. CONCLUSIONS: Approximately 1 of 4 patients with seeT0 at the time of radical cystectomy harbored residual muscle invasive bladder cancer. These prospective data definitively confirm major limitations of endoscopic assessment for pT0 bladder cancer. Future work should focus on novel imaging and biomarker strategies to optimize evaluations before radical cystectomy for improved decision making regarding bladder preservation.

Bacillus Calmette-Guérin Packaged for Percutaneous Vaccination Can Be Safely Used for Intravesical Instillation in Patients with Urothelial Carcinoma of the Bladder.

INTRODUCTION: Bacillus Calmette-Guérin production is limited worldwide with stuttering shortages affecting patient access. Our institution received 50 vials of bacillus Calmette-Guérin labeled for percutaneous administration, and upon discussion with our clinical team and approval by the Pharmacy and Therapeutics Committee we used the percutaneous formulation in place of the intravesical formulation. We report our experience. METHODS: Between February and April 2019 patients were treated with a third of a vial dose either with percutaneous or intravesical bacillus Calmette-Guérin. American Urological Association Symptom Score and Quality of Life survey and an additional 6-question survey (querying presence of suprapubic pain, hematuria, fevers, malaise, skin rashes, testicular/groin pain) were administered. Statistical analyses comparing the 2 groups were performed with SPSS version 22 software. RESULTS: A total of 30 patients with 73 intravesical instillations were evaluated with 34 patients receiving intravesical and 39 percutaneous bacillus Calmette-Guérin. We found no significant differences when comparing intravesical vs percutaneous bacillus Calmette-Guérin groups in terms of American Urological Association Symptom Score (6.1 vs 6.9, p=0.177), Quality of Life score (1.3 vs 1.7, p=0.132), fevers (2.9% vs 0%, p=0.300), hematuria (14.7% vs 2.8%, p=0.075), suprapubic pain (10.1% vs 4.3%, p=0.129), skin rashes (1.4% vs 0%, p=0.307) and feeling of general fatigue and malaise (15.7% vs 8.6%, p=0.126). CONCLUSIONS: Intravesical instillation of percutaneous bacillus Calmette-Guérin appears to be a safe alternative to intravesical bacillus Calmette-Guérin during times of shortage. Development of additional strains, use of alternative intravesical therapies and incentivizing bacillus Calmette-Guérin production through policy change and/or alternative funding may also help avoid bacillus Calmette-Guérin supply shortages in the future.

Predictive Nomogram for Recurrence following Surgery for Nonmetastatic Renal Cell Cancer with Tumor Thrombus.

PURPOSE: Following surgery for nonmetastatic renal cell carcinoma with tumor thrombus the risk of recurrence is significant but variable among patients. The purpose of this study was to develop and validate a predictive nomogram for individual estimation of recurrence risk following surgery for renal cell carcinoma with venous tumor thrombus. MATERIALS AND METHODS: Comprehensive data were collected on patients with nonmetastatic renal cell carcinoma and thrombus treated at a total of 5 institutions from 2000 to 2013. Independent predictors of recurrent renal cell carcinoma from a competing risks analysis were developed into a nomogram. Predictive accuracy was compared between the development and validation cohorts, and between the nomogram and the UISS (UCLA Integrated Staging System, SSIGN (Stage, Size, Grade and Necrosis) and Sorbellini models. RESULTS: A total of 636 patients were analyzed, including the development cohort of 465 and the validation cohort of 171. Independent predictors, including tumor diameter, body mass index, preoperative hemoglobin less than the lower limit of normal, thrombus level, perinephric fat invasion and nonclear cell histology, were developed into a nomogram. Estimated 5-year recurrence-free survival was 49% overall. Five-year recurrence-free survival in patients with 0, 1, 2 and more than 2 risk factors was 77%, 53%, 47% and 20%, respectively. Predictive accuracy was similar in the development and validation cohorts (AUC 0.726 and 0.724, respectively). Predictive accuracy of the thrombus nomogram was higher than that of the UISS (AUC 0.726 vs 0.595, p = 0.001), SSIGN (AUC 0.713 vs 0.612, p = 0.04) and Sorbellini models (AUC 0.709 vs 0.638, p = 0.02). CONCLUSIONS: We present a predictive nomogram for postoperative recurrence in patients with nonmetastatic renal cell carcinoma with venous thrombus. Improving individual postoperative risk assessment may allow for better design and analysis of future adjuvant clinical trials.
