Association of Surgical Approach and Urinary Diversion in Radical Cystectomy for Bladder Cancer With Costs and Readmission: Results From a Large Private Health Insurance Cohort.

INTRODUCTION: We sought to assess the comparative hospital outcomes and costs among a population-based cohort of bladder cancer patients by surgical approach and diversion. METHODS: From a privately insured national database, we identified all bladder cancer patients who underwent open or robotic radical cystectomy and ileal conduit or neobladder from 2010 to 2015. The primary outcomes were length of stay, readmissions, and total health care costs at 90 days from surgery. We used multivariable logistic regression and generalized estimating equations to assess for 90-day readmission and health care costs, respectively. RESULTS: Most patients underwent open radical cystectomy with ileal conduit (56.7%; n = 1,680) followed by open radical cystectomy with neobladder (22.7%; n = 672), robotic radical cystectomy with ileal conduit (17.4%; n = 516), and robotic radical cystectomy with neobladder (3.1%; n = 93). On multivariable analysis, patients had higher odds of 90-day readmissions for open radical cystectomy and neobladder (OR: 1.36; P = .002) and robotic radical cystectomy with neobladder (OR 1.60; P = .03) relative to open radical cystectomy with ileal conduit. After adjusting for patient covariates, we also found lower adjusted total 90-day health care costs for open radical cystectomy with ileal conduit ($67,915) and open radical cystectomy with neobladder ($67,371) compared to robotic radical cystectomy with ileal conduit ($70,677) and neobladder ($70,818; P < .05). CONCLUSIONS: In our study, neobladder diversion was associated with higher odds of 90-day readmission, while robotic surgery increased total 90-day health care costs.

Solitary brain metastasis after recurrent adenocarcinoma of the prostate.

Prostate cancer is rarely metastatic to visceral organs, and even less commonly to the brain. Recent data suggests brain metastasis from prostatic adenocarcinoma occur in 0.16% of patients, and almost universally in the setting of very high-volume disease. We present a man with an abruptly symptomatic brain lesion that developed at a PSA value of 1.5 ng/mL with no other known metastatic disease and required emergent neurosurgical resection. The patient had been initially treated with radiotherapy for Grade Group 4 prostate cancer in 2005 with a long period of PSA suppression.

Metastatic renal cell carcinoma to the prostate and seminal vesicle.

Renal cell carcinoma (RCC) a common malignancy with potential to metastasize to visceral organs. However, it uncommonly spreads to the lower genitourinary tract. We present a man with a history of RCC status post radical nephrectomy in April 2012. He presented 8 years later with obstructive lower urinary tract symptoms and an elevated prostate specific antigen (PSA). Further imaging showed a large enhancing mass with internal blood vessels posterior to the left prostate and seminal vesicle. A prostate biopsy was performed and consistent with metastatic RCC. He was ultimately treated with immunotherapy and focal stereotactic radioablation.
