Seeking men and women with cancer of the esophagus or gastric junction for a study of whether a blood sample analyzed to find evidence of a cancer tumor (liquid biopsy) might be a useful tool to predict how well the cancer has responded to treatment.
We are collecting blood samples from participants at four different time points (before treatment, before surgery, about two weeks after surgery and 3-4 months after surgery) for liquid biopsy analysis.
What we're hoping for
Evaluate the use of liquid biopsy, which is a cancer screening using blood samples to detect cancerous tumor cells, to predict how well esophageal or gastric junction cancer has responded to treatment.
