The case of recurrent pancreatic cancer presented in this issue of ONCOLOGY by Dr. Dasari and colleagues illustrates the significant challenges faced by both medical and surgical oncologists in the management of pancreatic adenocarcinoma. This case describes an all-too-common clinical scenario: A thorough preoperative assessment indicating resectable disease, but with the initial medical oncology assessment revealing overt metastatic disease. The development of distant metastases in the short interval between pre-operative and post-operative staging reflects the aggressive underlying biology associated with a subset of patients with this malignancy. New insight into the genetic evolution of pancreas adenocarcinoma from Yachida and colleagues suggests that the latent period between initial development of pancreas adenocarcinoma and development of metastases is measured in years, however detection of the diagnosis at an early stage remains an ongoing challenge for clinicians.[1]

Cancers of the gallbladder and biliary tract are uncommon malignancies in the United States with a combined incidence of less than 8,000 new cases per year, about 5,000 of which are gallbladder cancer and about 2,000 to 3,000 of which are cholangiocarcinomas, including intrahepatic, hilar, and distal bile duct cancers.[1] For gallbladder cancer with mucosa-confined disease, the 5-year survival rate is approximately 32%, and for advanced disease, less than 10% of patients survive longer than 1 year.[2]
