Age-adapted high-dose chemotherapy followed by autologous stem cell transplantation or conventional chemotherapy and maintenance therapy in fit elderly patients* with initial diagnosis of primary cerebral lymphoma.

Phase 1

Active, not recruiting

• Conditions: Primary diffuse large B-cell lymphoma of the central nervous system(PCNSL) is a rare lymphoma affecting only the central nervous systemcompartment. PCNSL patients are typically 60 years or older and havepoor prognoses. Considering the poor prognosis of this patientpopulation, this randomised phase III trial proposal is of great clinicalimportance to provide patients optimal treatment.; Therapeutic area: Diseases [C] - Blood and lymphatic diseases [C15]
