Study Details

Brief summary:

The overarching goals of this study are to measure levels of circulating tumor DNA (ctDNA) in patients with early stage diffuse large B cell lymphoma (DLBCL), to assess the change in ctDNA during treatment in order to prospectively identify markers of treatment failure, and to use ctDNA as a future tool for response adapted therapy.

Eligibility Criteria

Sex: All

Age: 18+

Healthy Volunteers: Not accepted

Inclusion Criteria:

  • Previously untreated limited stage non bulky DLBCL; defined as limited stage by routine staging criteria in lymphoma involving FDG-PET and bone marrow biopsies (the Lugano criteria)\[21\]
  • Patients with grade 3B follicular lymphoma and transformed indolent lymphoma are included
  • Ages ≥ 18
  • Measurable disease, assessable by radiographic examination with FDG-PET showing involvement
  • Access to archived or fresh/frozen tumor biopsies
  • No uncontrolled medical comorbidities
  • Adequate cardiac function (EF > or equal to 50%), no unstable angina
  • Adequate renal function (GFR > 60)
  • Adequate liver function (liver function tests should be no greater than 2 x upper limit of normal) including normal bilirubin levels, no greater than 2 x upper limit of normal unless patient has a history of Gilbert's disease
  • Adequate marrow reserves as indicated by complete blood count in the judgment of the treating investigator

Exclusion Criteria:

  • Pregnancy, positive serum HCG within 28 days of enrollment, or breast-feeding
