Level III-retrospective comparative study.

Invasive non-urachal adenocarcinoma of the bladder is a rare diagnosis. Survival benefits in patients without metastatic disease are seen only in those patients undergoing definitive surgery.

Purpose Previous studies have noted increased utilization of perioperative chemotherapy over time. The goal of this study was to determine trends in perioperative chemotherapy use within a contemporary population. Materials and Methods The National Cancer Database was queried for patients diagnosed with cT2-4N0M0 urothelial muscle invasive bladder cancer from 2011 to 2015 and underwent subsequent radical cystectomy. We retrospectively analyzed factors associated with perioperative chemotherapy and evaluated overall treatment trends in the use of neoadjuvant and adjuvant chemotherapy. Linear regression, logistic regression, Cox regression, and Kaplan–Meier analysis were performed. Results In total, 7,101 patients met inclusion criteria for analysis. The use of perioperative chemotherapy increased from 46.4% in 2011 to 57.2% in 2015 (p=0.003). Neoadjuvant chemotherapy use increased from 22.9% to 32.3% (p=0.007) over the time period analyzed, while adjuvant chemotherapy use experienced no significant change (23.5% to 24.9%, p=0.182). Logistic regression demonstrated that increased age and Charlson Comorbidity Index were predictors of not receiving chemotherapy (p<0.05), while those with increasing T stage, income above $48,000, and insurance other than Medicaid or Medicare were more likely to receive perioperative chemotherapy (p<0.05). Kaplan–Meier analysis revealed patients receiving neoadjuvant chemotherapy had the best 5-year overall survival at 48.3% compared to adjuvant chemotherapy (42.6%) or no chemotherapy (37.8%) (p<0.001). Conclusions The increasing use of perioperative chemotherapy noted in prior studies has continued through 2015. Neoadjuvant chemotherapy appears to drive this increase while adjuvant chemotherapy utilization remains unchanged. Clinical and socioeconomic factors affect utilization of perioperative chemotherapy.

Current management of high-grade blunt renal trauma favors a nonoperative approach when possible. We performed a retrospective study of high grade blunt renal injuries at our level I trauma center to determine the indications and success of nonoperative management (NOM). 47 patients with blunt grade IV or V injuries were identified between October 2004 and December 2013. Immediate operative patients (IO) were compared to nonoperatively managed (NOM). Of the 47 patients, 3 (6.4%) were IO and 44 (95.6%) NOM. IO patients had a higher heart rate on admission, 133 versus 100 in NOM (P = 0.01). IO patients had a higher rate of injury to the renal vein or artery (100%) compared to NOM group (18%) (P = 0.01). NOM failed in 3 of 44 patients (6.8%). Two required nonemergent nephrectomy and one required emergent exploration resulting in nephrectomy. Six NOM patients had kidney-related complications (13.6%). The renal salvage rate for the entire cohort was 87.2% and 93.2% for NOM. Nonoperative management for hemodynamically stable patients with high-grade blunt renal trauma is safe with a low risk of complications. Management decisions should consider hemodynamic status and visualization of active renal bleeding as well as injury grade in determining operative management.
