About this study

Official title: Brazilian Reality in the Diagnosis and Treatment of Diffuse Large B Cell Lymphoma - BRA-DLBCL: Multicenter Retrospective Study (Real World Evidence - RWE)

National, multicenter, non-randomized, retrospective observational study (Real World Evidence-RWE) to analyze the epidemiological profile of diffuse large B cell lymphoma, clinical management, treatment in molecular subgroups, progression profile and patient survival outcomes enrolled and treated within the last 6 years (2017 to 2022), in national cancer reference centers.

Read the detailed description

Diffuse large B-cell lymphoma management is a challenge in clinical setting, as the heterogeneity of conditions due to the molecular complexity of DLBCL may limit treatment response. Other major factor is that in Brazil we lack evidence of treatment response profiling regarding this molecular complexity. To know the epidemiological profile of DLBCL, together with the first-line treatment profile that has been adopted in reference centers, as well as the management of relapsing, is essentially important in generating evidence that add up to actions targeting the improvement of patient care, providing them with better treatments. The Brazilian reality of clinical presentation, management profile, employed treatments and response rate is little known. Considering the Brazilian reality of a continental country, where healthcare services in reference centers present heterogeneous realities, analyzing clinical routine data may generate important evidence (RWE) to comprise the understanding on treatments effectiveness. Generated evidence has the potential to help understanding the reality of Brazilian patients, as well as supporting new regional researches.

Study groups in NCT05958134
Study groupRoleWhat they receive
Diagnosed with diffuse large B-cell lymphoma, and classified regarding the cell of originRetrospective data collection will be carried out from the medical records of the participants included in the study. Will be held description of the epidemiological profile and pathological staging of diffuse large B-cell lymphoma conditions (DLBCL/LDGCB), imaging profiling, together with first-line treatment used in subgroups of germinal center or activated B-cell, in patients followed in Brazilian reference cancer treatment centers, within the last 6 years (between 2017 and 2022).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Disease staging

    Description of the staging of diffuse large B-cell lymphoma conditions in patients followed in Brazilian reference cancer treatment centers

    Measured: Time Frame: 6 years (Time of retrospective observational analysis of the study)

  2. Time between diagnosis and start of treatment

    Description of the time between diagnosis and start of treatment

    Measured: Time Frame: 6 years (Time of retrospective observational analysis of the study)

  3. Progression-free Survival

    Progression-free Survival will be evaluated as the time from the beginning of treatment, considering each line of treatment, to the objective progression of tumor or death

    Measured: Time Frame: 6 years (Time of retrospective observational analysis of the study)

  4. Overall Survival

    Overall Survival will be evaluated as the time from the diagnosis of the hematological disease at any staging until all-cause death

    Measured: Time Frame: 6 years (Time of retrospective observational analysis of the study)

Questions about this trial

What is this clinical trial studying?

An observational study of Diffuse Large B Cell Lymphoma, run by AstraZeneca at 4 sites in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 23 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Disease staging (time frame: Time Frame: 6 years (Time of retrospective observational analysis of the study)). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2025.
