NCT05958134

Brief Summary

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.

Outcome Measures

Primary Outcomes (4)

  • Disease staging

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

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

  • Time between diagnosis and start of treatment

    Description of the time between diagnosis and start of treatment

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

  • 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

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

  • Overall Survival

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

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

Study Arms (1)

Diagnosed with diffuse large B-cell lymphoma, and classified regarding the cell of origin

Retrospective 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).
