Purpose:

This pilot clinical trial studies tumor-specific markers (clonotype), blood tests, and positron emission tomography (PET)/computed tomography (CT) in predicting treatment response at different times during chemotherapy in patients with diffuse large B-cell lymphoma that has come back (relapsed) or does not respond to treatment (refractory). Studying samples of blood in the laboratory from patients during chemotherapy may help doctors learn more about the effects of treatment on cells and may help doctors determine whether patients are responding to treatment. PET/CT scan procedures are done at the same time with the same machine and the combined scans give more detailed pictures of areas inside the body than either scan gives by itself and may help doctors find out how well treatment is working.


Study summary:

PRIMARY OBJECTIVES: I. To evaluate the ability of blood based detection of a tumor-specific clonotype and metabolic profiling and functional imaging to predict response to standard immunochemotherapy. SECONDARY OBJECTIVES: I. To evaluate the optimal time points to create the diffuse large B-cell lymphoma (DLBCL) response prediction model. TERTIARY OBJECTIVES: I. To evaluate the prognostic value of clinical factors, cell of origin subtype, and circulating immune cell subsets for response to therapy. II. To evaluate for novel genomic aberrations or signatures which correlate with therapeutic failure. III. To evaluate the ability of additional positron emission tomography (PET)/computed tomography (CT) imaging interpretation techniques to correlate with clinical outcomes. IV. To evaluate the correlation of blood-based detection of clonotype with fludeoxyglucose F-18 (FDG) PET/CT disease assessment. V. To evaluate the utility of alternative methods of minimal residual disease detection. VI. To evaluate measurement of circulating metabolic profiling with imaging results and clinical outcomes. OUTLINE: Patients receive standard salvage chemotherapy as determined by the treating physician. Patients undergo FDG PET/CT scans at baseline (between days -21 to 0), on day 4 after completion of first high-dose chemotherapy, on day 21 after completion of the first course of chemotherapy, and on day 42 after the end of the second course of chemotherapy. Blood samples are also collected for tumor-specific clonotype and metabolic profile at baseline (days -5 to 0) and on days 4, 8, 21, and 42.


Criteria:

Inclusion Criteria: - Subject/legal representative willing and able to provide written informed consent - Histologically confirmed aggressive B-cell DLBCL, including follicular lymphoma (FL) transforming to DLBCL and high grade B-cell lymphoma - Willing to provide existing relapse-confirmatory DLBCL tumor sample - Relapsed from or refractory to at least one treatment containing a CD20 monoclonal antibody combined with anthracycline-based chemotherapy - CT scans showing involvement of 1 or more clearly demarcated lesions with a long axis > 1.5 cm and short axis >= 1.0 cm - Baseline FDG-PET/CT scans must demonstrate at least one hypermetabolic lesion as defined by the Deauville criteria localizing to CT-defined anatomical tumor sites - Suitable candidate for therapy with standard salvage chemotherapy and autologous stem cell transplant (ASCT) as determined by the treating physician - Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2 - Life expectancy of >= 12 weeks as estimated by the treating physician - Negative serum beta-human chorionic gonadotropin (beta-hCG) test (women of childbearing potential only) - Hemoglobin >= 8.5 g/dL - Absolute neutrophil count (ANC) >= 1500/mm^3 - Platelet count >= 75,000/mm^3 - Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 5 x institutional upper limit of normal (ULN) for cases involving liver metastasis and =< 3 x institutional ULN for all other cases - Bilirubin =< 2 x ULN (unless related to lymphoma) or =< 5 x ULN for subjects with documented or suspected Gilbert's disease - Serum creatinine =< 1.5 x ULN or calculated creatinine clearance (CrCl) >= 50 mL/min as determined by the Cockcroft-Gault equation Exclusion Criteria: - Any condition that, in the opinion of the investigator, would interfere with the interpretation of study results or subject safety including non-malignant FDG avid diseases such as sarcoidosis or other granulomatous disease - Uncontrolled diabetes mellitus - Concurrent enrollment in another clinical study where they are receiving non-standard salvage chemotherapy, (i.e., concurrent enrollment is allowable if the patient is receiving standard salvage chemotherapy and research imaging is allowed) - Any chemotherapy, radiotherapy, immunotherapy, biologic, or investigational therapy for treatment of lymphoma within 14 days prior to treatment - Symptomatic congestive heart failure
