Modeling Clinical Processes to Consent Research Donors of Remnant Biospecimens in an Outpatient Cardiology Clinic.

Informed consent for research biospecimen donations is traditionally obtained through a face-to-face interaction with research staff and by signing an Institutional Review Board (IRB)-approved printed form. Electronic signatures (eSign) are routinely used in the electronic medical record (EMR) for the consenting of clinical services after patients review printed documentation. Our goal was to develop an electronic self-consenting workflow that mimicked clinical services.

EGFR mutations detected in plasma are associated with patient outcomes in erlotinib plus docetaxel-treated non-small cell lung cancer.

Purpose: Activating mutations in the epidermal growth factor receptor (EGFR) are associated with enhanced response to EGFR tyrosine kinase inhibitors in non-small cell lung cancer (NSCLC), whereas KRAS mutations translate into poor patient outcomes. We hypothesized that analysis of plasma for EGFR and KRAS mutations from shed tumor DNA would have clinical utility.

Methods: An allele-specific polymerase chain reaction assay using Scorpion-amplification refractory mutation system (DxS, Ltd) was used to detect mutations in plasma DNA from patients with advanced stage NSCLC treated as second- or third-line therapy on a phase I/II trial of docetaxel plus intercalated erlotinib.
