Targeting CA 19-9 with a humanized monoclonal antibody at the time of surgery may decrease recurrence rates for patients undergoing resections for pancreatic cancer, cholangiocarcinoma and metastatic colorectal cancer.

Shreya Gupta, James D McDonald, Reed I Ayabe, Tahsin M Khan, Lauren A Gamble, Surajit Sinha, Cathleen Hannah, Andrew M Blakely, Jeremy L Davis, Jonathan M Hernandez,

Operable gastrointestinal cancers continue to pose significant challenges. Radical resections are rarely curative, and chemotherapy is able to reduce tumor recurrence for only a small percentage of patients. Despite the obvious advantages of extirpation of the identifiable tumor(s), the inflammatory milieu that accompanies surgery and the obligate time off cytotoxic ... Read more >>

Reed I Ayabe, Raja R Narayan, Samantha M Ruff, Michael M Wach, Winifred Lo, Pieter M H Nierop, Seth M Steinberg, R Taylor Ripley, Jeremy L Davis, Bas G Koerkamp, Michael I D'Angelica, T Peter Kingham, William R Jarnagin, Jonathan M Hernandez,

BACKGROUND:Adrenocortical carcinoma (ACC) is an aggressive malignancy that frequently metastasizes to the liver. Given the limitations of systemic therapy in this setting, we sought to determine characteristics associated with a two-fold increase in survival with resection/ablation compared to that reported with chemotherapy alone (∼12 months). METHODS:Patients who underwent resection/ablation at ... Read more >>
