Brief Summary
The goal of this single-arm, prospective study is to learn if high dose gemcitabine, busulfan and thiotepa with autologous stem cell transplantation to treat primary or relapse central nervous system lymphomas. It will learn about the safety and efficacy of combination therapy. The main question it aims to answer is: Efficacy and safety of the combination of high dose gemcitabine, busulfan and thiotepa as a bridging therapy to ASCT in patients with CNSL. Participants will: Take gemcitabine (2.5 g/m²) was administered intravenously (IV) on Days -9 and -3, Busulfan (3.2 mg/kg) was given IV over 3 hours on Days -9 to -7, and thiotepa (5 mg/kg) was administered IV on Days -5, -4, and -3. Peripheral stem cells were infused on Day 0. Visit the clinic for checkups and tests in accordance with the International Primary CNS Lymphoma Group (IPCG). Researchers will observe the patients receiving GemBuTT regimen as conditioning therapy in CNSL.
