Metastatic esophagogastric adenocarcinoma: trends in first-line treatment and predictive factors for the implementation of HER2 testing in clinical practice during the first year after trastuzumab market approval.

Purpose: Little is known about the use of first-line chemotherapy in clinical practice in patients with advanced esophagogastric adenocarcinoma, and no data have been published regarding potential obstacles for the implementation of molecular testing for targeted agents in this patient group. Here, we sought to evaluate factors influencing treatment decisions with special focus on the implementation of HER2 testing during the first year after trastuzumab market approval in Germany.

Methods: A total of 754 patients undergoing treatment decisions for palliative first-line therapy in 2010 were documented using Therapiemonitor(®).

Population-based patterns of care in the first-line treatment of patients with advanced esophagogastric adenocarcinoma in Germany.

Background: Randomized studies proved the efficacy of new drugs for the systemic treatment of advanced gastric cancer in the past 5 years. However, little is known about the use of firstline chemotherapy in clinical practice in patients with advanced or metastatic adenocarcinoma of the esophagogastric junction (AEG) and the stomach. We investigated temporal trends in therapy and factors influencing treatment decisions for these patients during a 4-year period.
