CHOEP-14 + Rituximab With CNS Prophylaxis in Patients Less Than 65 Years With Diffuse Large B-Cell Lymphoma/Follicular Lymphoma Grade III, Stage II-IV With Risk Factors (Age Adjusted IPI) ≥ 2. A Phase II Study
Pathology:
Patients may be included on the bases of the histological diagnosis of the local
pathologist. The specimen will be reviewed by a central pathologist in each country
Treatment:
All patients receive CHOEP-14 with rituximab x 6 with the support of G-CSF followed by high
dose cytarabine i.v. and high dose methotrexate i.v.Intrathecal (i.t.) CNS prophylaxis in
combination with chemotherapy is not to be given, but i.t. methotrexate may be given once
after initial liquid sampling. Radiotherapy will be given at the discretion of the
individual centres.
Investigations before, during and after treatment:
The disease status will be assessed prior to treatment start, after 3 cycles of CHOEP +
rituximab and after completion of the treatment schedule. Positron Emission Tomography (PET)
using F18 deoxyglucose may be performed after fulfillment of treatment. Persistent,
suspected lymphoma tissue should whenever possible be confirmed with a biopsy, otherwise the
patient will be regarded as PR and second line therapy will be considered (see schematic
outline).
Clinical and radiological (CT) assessment are performed at pretreatment and subsequently on
sites initially involved, and bone marrow biopsy if initially involved
- After the 3rd course
- After the last course (within one month) of chemotherapy (biopsy if indicated)
- After radiotherapy (for patient given radiotherapy as part of the primary treatment)
Clinical follow-up:
- 4x per year during the first and second year of follow-up
- 2x per year during the third, fourth and fifth year of follow-up
Radiological investigations at follow up:
-CT after 6, 12 and 24 months of sites initially involved. CT abdomen in all cases after 12
and 24 months. X-ray of the thorax (if CT thorax is performed) after 6, 12 and 24 months
Interventional
Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment
Time to treatment failure
Interval between the registration date and the date of documented progression or lack of response, first relapse, death for any reason or discontinuation/change of therapy because of toxicity, whichever occurs first. Otherwise, patients will be censored at the last date they were known to be alive. For patients not responding at any time point on study treatment, TTF is defined as 1 day.
