Treatment of Diffuse Large B-Cell Lymphoma with Testicular Involvement

Diffuse large B-cell lymphoma presenting with testicular involvement poses distinct management considerations beyond the primary tumour, due to well-recognised patterns of recurrence at specific sites.

Clinical Scenario

This protocol addresses patients with testicular involvement by diffuse large B-cell lymphoma. In this setting, there is a significant risk of recurrence in the contralateral testicle, as well as a substantial risk of central nervous system (CNS) recurrence — both of which inform the overall treatment approach.

Treatment Approach (Overview)

Management in this scenario includes locoregional radiation directed at the contralateral testicle, alongside systemic CNS prophylaxis — with the complete regimen, sequencing, and additional components detailed in the full protocol.

However, there is a significant risk of recurrence in the contralateral testicle and external beam radiation therapy is commonly given to the contralateral testicle.

There is also a substantial risk of central nervous system (CNS) recurrence and CNS prophylaxis is routinely given.
