Survival comparison between endoscopic and surgical management for patients with upper tract urothelial cancer: a matched propensity score analysis using surveillance, epidemiology and end results-Medicare data.
The researchers sought to determine survival differences among patients receiving endoscopic vs surgical management for upper tract urothelial carcinoma (UTUC). They found that although initial survival outcomes are similar for endoscopic and surgical management of nonmuscle-invasive, low-grade UTUC, both cancer-specific survival and overall survival are significantly inferior for the endoscopic management group in the longer term. They also found that transition from initial endoscopic management to surgical intervention appears to have limited impact on survival.

The effect of graft type on mortality in liver transplantation for hepatocellular carcinoma.
The researchers aimed to: (1) examine the risk of mortality in liver transplantation for hepatocellular carcinoma (HCC), (2) to establish if this risk is affected by partial graft use, and (3) to determine if this effect is mitigated by improved tumor-associated risk stratification. They found that the risk of mortality following LT does not differ by the type of graft used in recipients with favorable-risk HCC or those without HCC.

Does the use of neoadjuvant therapy for pancreatic adenocarcinoma increase postoperative morbidity and mortality rates?
The researchers used data from the NSQIP Pancreatectomy Demonstration Project (11/2011 to 12/2012) to identify patients with pancreatic adenocarcinoma who did and did not receive neoadjuvant therapy. They found that despite evidence for more extensive disease, patients receiving neoadjuvant therapy did not experience more complications. Neoadjuvant radiation was associated with lower pancreatic fistula rates.

Treatment of diffuse large B-cell lymphoma in the elderly: regimens without anthracyclines are common and not futile.
This study characterized treatment choices and compared the 3-year overall survival rates of 8262 Medicare beneficiaries diagnosed with diffuse large B-cell lymphoma in 2000 – 2006. It found that patients treated with anthracycline-containing regimens with rituximab have the highest survival rates when all available clinical features are accounted for.
