PRIMARY OBJECTIVES:
I. Determine whether ILN biochip can be used to detect molecular marker(s) to monitor treatment response in patients with newly diagnosed diffuse large B-cell lymphoma (DLBCL).
II. Determine whether ILN biochip can promote early detection of disease relapse in patients with DLBCL.
OUTLINE:
Participants' blood samples undergo ILN biochip testing at diagnosis, before and after every course of chemotherapy, every 3 months for 2 years, and at relapse.
