Laparoscopic and open distal pancreatectomy: a comparison of outcomes.

Laparoscopic (lap) pancreatic surgery has been increasingly reported since its introduction in 1992. A retrospective analysis of consecutive patients undergoing elective lap and open distal pancreatectomy from 2002 to 2007 was performed. Univariate analysis was completed to evaluate perioperative variables.

ErbB3 expression and dimerization with EGFR influence pancreatic cancer cell sensitivity to erlotinib.

Abnormal expression and signaling of ErbB receptors has been implicated in multiple epithelial malignancies, including pancreatic cancer. Erlotinib, an epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI), has been recently approved for pancreatic cancer treatment, but there are no reliable predictors of patient response. Expression of additional ErbB receptors seems to influence tumor response to EGFR-targeted therapy.
