Immune Reconstitution and Biomarker Identification in Patients With Newly Diagnosed Low and Intermediate Risk Hodgkins Lymphoma Receiving Chemotherapy With or Without Radiation Therapy: TXCH-HD-12A
At first the subject will have 2 cycles of cancer drugs (Doxorubicin, Bleomycin,
Vincristine, Etoposide, Cyclophosphamide). The doctors call this combination of cancer drugs
ABVE-PC for short. A cycle equals 21 days. The cancer drugs will be given intravenously
Those patients evaluated as having an early response to treatment will be put in the group
of Rapid Early Responders (RERs). The RER group includes those patients whose disease has
been reduced by 60% or more. The next step for patients with RERs is 2 more cycles of
ABVE-PC chemotherapy followed by another evaluation of their response. Those determined to
have a complete response (at least an 80% disease reduction) will receive no further
therapy. Those patients determined to have less than a complete response will receive
radiation therapy within 6 weeks after the last cycle or when blood counts are recovered.
Radiation therapy will be given to the involved areas and by the standard of care of this
hospital (Texas Children's Hospital). After radiation the subject will be off treatment.
Patients with disease reduction less than 60% are put in the group of Slow Early Responders
(SERs). The next step for patients with SER is 2 cycles of DECA (Dexamethasone, Etoposide,
Cytarabine, and Cisplatin). On Days 1 and 2, the subject will be given dexamethasone IV
first; afterwards, then they will receive the Etoposide and Cytarabine mixture. Cisplatin
will be given by IV only on Day 1.
BIOLOGY TESTS The doctors are investigating molecules in tumors and blood that may help them
better understand the biology of Hodgkin's Disease. These studies may also help them
understand differences in patients' responses to therapy.
TISSUE FOR BIOMARKER STUDIES The doctors want to study the material that shows the make-up
of the cancer (the genes of the cancer tissue) and the special "markers" of the tissue.
Tissue from the subject's cancer biopsies will be used for these studies. They will collect
these samples when the subject has a biopsy for clinical reasons.
IMMUNE FUNCTION AND BIOMARKER BLOOD TESTS The doctors also want to collect blood samples to
study the subject's immune system and to look at biomarkers in the blood.
Allocation: Non-Randomized, Intervention Model: Parallel Assignment, Masking: Open Label, Primary Purpose: Treatment
Response to therapy from Day 1 of Treatment
To define the general immune recovery in patients with low and intermediate risk HD undergoing chemotherapy with or without radiation therapy. Descriptive analysis of response to therapy, event-free survival, overall survival, relapse, and infection will be summarized using summary statistics.
