Evaluate a Treatment Adapted to the PET Response Compared to a Standard Treatment, for Low Risk DLBCL CD 20+ Patients
- Conditions
- DLBCL
- Interventions
- Drug: RCHOP21
- Registration Number
- NCT01285765
- Lead Sponsor
- The Lymphoma Academic Research Organisation
- Brief Summary
In this study, the investigators purpose is to evaluate the adaptation of treatment with early response based on PET scan results after 2 cycles of chemotherapy, for patient aged from 18 to 80 years, with low IPI DLBCL.
This is an open randomized study.
The primary endpoint is to evaluate the 3 years PFS with the aim to demonstrate the non inferiority of the experimental arm in comparison to standard arm:
In standard arm, the patients will receive 6 cycles of R-CHOP 21 without taking into account of PET scan results after 2 cycles.
In experimental arm, early good responder patients (defined as having a negative PET scan after 2 cycles, confirmed after 4 cycles) will receive only 4 cycles of R-CHOP 21.
In both arms, if the PET scan remains positive after 4 cycles of chemotherapy, a biopsy exam is needed to confirm the failure and an intensive chemotherapy is then recommended.
All of the patients, in both arms, will have an early evaluation with PET scan. All PET scan will be reviewed by a group of expert according to Deauville criteria defined by Meignan et al to adapt the decision after the 2nd cycle in experimental arm and after the 4th cycle for all patients. The final evaluation of response will be made according to 2007 Cheson's criteria.
- Detailed Description
Localized stages DLBCL with low IPI (aaIPI = 0) have a very good prognostic after a standard immuno-chemotherapy with 6 cycles of R-CHOP 21. Five years PFS is estimated over 75%, whatever the age of the patient.
PET scan is actually considered as "the gold standard" for the initial staging and the evaluation of response after treatment. With this new technique, the response criteria have been redefined by Cheson and al. in 2007. Moreover, several recent studies showed that early evaluation of response with PET scan after only 2 cycles of chemotherapy was accurate to define two groups of patients:
"Early-good-responders", when PET scan is negative "Early-poor-responders", when PET scan remains positive Prognostic for the first group is very good, and for the second poorer. At the present time, the interest of the modification and/or the intensification of the treatment for the early-poor-responder patients is not demonstrated by any publication. New studies are ongoing for patients with advanced stages of DLBC NHL (GELA trial LNH 07-3B) or Hodgkin's lymphoma (GELA and EORTC trial H10); the aim is to evaluate a new strategy of treatment adapted to early response criteria.
No trial has already been made for low IPI DLBCL. In this study, the investigators purpose is to evaluate the adaptation of treatment with early response based on PET scan results after 2 cycles of chemotherapy, for patient aged from 18 to 80 years, with low IPI DLBCL.
