Key result

First-line R-DA-EPOCH treatment for primary mediastinal large B-cell lymphoma achieved a 3-year progression-free survival of 92.8% (95% CI 88.1-97.7%) and overall survival of 97.2%.

Why the study?

R-DA-EPOCH was adopted internationally for primary mediastinal large B-cell lymphoma, but few large real-world studies with long-term follow-up had been published.

Population

122 adults with PMBL from 9 centres in England, Scotland and Australia

Comparison

First-line R-DA-EPOCH

Design

Multi-centre retrospective study

Follow-up

Median 3.2 years (range: 0.3 - 11.6)

Implication

Dose-intensified regimens may reduce RT need in PMBL; leaves open survival benefit versus R-CHOP plus RT in trials.

Structured PICO

P
Population
122 adults with primary mediastinal large B-cell lymphoma treated with first-line R-DA-EPOCH, followed for a median of 3.2 years.
E
Exposure
First-line R-DA-EPOCH chemotherapy regimen (majority received 6 cycles; 13% received R-CHOP as first cycle for stabilisation)
O
Outcome
3-year progression-free survival (PFS) and overall survival (OS)hard clinical

Real-world data confirms that first-line R-DA-EPOCH is highly effective for primary mediastinal large B-cell lymphoma, yielding excellent 3-year progression-free and overall survival.

Cite This Study

Santarsieri et al. (2022) conducted a cohort in Primary mediastinal large B-cell lymphoma (PMBL) (n=122). R-DA-EPOCH was evaluated on 3-year progression-free survival (95% CI 88.1-97.7). First-line R-DA-EPOCH treatment for primary mediastinal large B-cell lymphoma achieved a 3-year progression-free survival of 92.8% (95% CI 88.1-97.7%) and overall survival of 97.2%.
