Secondary Prognostic Index in RefrActory Lymphoma

• Conditions: Refractory Diffuse Large B-Cell Lymphoma; Diffuse Large B Cell Lymphoma
• Interventions: Other: prognostic assessment

• Registration Number: NCT04804865
• Lead Sponsor: Weprom

Brief Summary

60% of patients with diffuse large B cell lymphoma are healed after first-line treatment which whatever the age. For the remaining 40% of patients (relapses and primary refractories):

* 38% of patients will be cured with a 2nd line including an autologous haematopoietic cell transplantation for those under 65 years.

* for older patients who are not eligible for a autograft: only 70% of patients will be able to receive 2nd line treatment with rates response less than 50%.

* the survival rate in patients receiving 3rd line treatment or more is 15% at 2 years. Actually, no standard of chemotherapy is offered to relapsed or refractory patients after 2 therapeutic lines. Subsequent lines lead to hospitalizations for infectious complications or transfusions without clear clinical benefit with often an impacted quality of life.

Palliative care is rarely offered as part of the treatment overall load.

Arm && Interventions

Group	Intervention	Description
population	prognostic assessment	The population includes adult patients. * Patients died from refractory or relapsed diffuse large-cell lymphoma. * Patients \<65 years of age eligible for an autologous transplant should have relapsed after the autologous transplant. * Patients \>65 years of age or not eligible after an autologous transplant must have received at least one RCHOP-type treatment line (2 cycles).

Primary Outcome Measures

Name	Time	Method
Overall survival	5 years	Time between the date of relapse or no response observed (after 2 lines of chemotherapy in young patients and one line for elderly patients) and the date of death regardless of the cause.

Secondary Outcome Measures

Name	Time	Method
the intensity dose of chemotherapy received	6 month	Total amount of chemotherapy administered relative to the theoretical dose calculated according to the patient's body surface area.
the Cumulative Illness Rating Scale for comorbidities score in patients over 65 years old	6 month	The cumulative illness rating scale for comorbidity score in elderly patients will be calculated according to the table proposed by Salvi et al. in 2008 (values :0 to 56; higher scores mean a worse outcome).
Median response time after each line	5 years	Time between the date when the first response criterion is observed (partial or complete response) and the date when the recurrence or progression is objectively documented
Event-free survival since diagnosis and after each line of treatment received	5 years	Time between the date of diagnosis and the date of the first event observed, then between the date of the first administration of each line of treatment administered and the date of onset of the first event observed.
