The effectiveness and harms of bortezomib in combination with chemotherapy for mantle cell lymphoma: A protocol for systematic review and meta-analysis

BACKGROUND: Chemotherapy with or without consolidation followed by autologous hematopoietic stem cell transplantation is the first-line treatment for mantle cell lymphoma. However, the effectiveness and safety of bortezomib-based chemotherapy for patients with mantle cell lymphoma is still uncertain. METHODS: In this systematic review, the electronic databases of Cochrane Central Register of Controlled Trials, EMBASE, and PUBMED will be searched from inception to May 1, 2020. Randomized controlled trials that assessed the effectiveness and safety of bortezomib in combination with chemotherapy for patients with mantle cell lymphoma will be included. The patient's important outcomes include overall survival, progression-free survival, overall response rate, quality of life, and serious adverse events (eg, grade III-IV peripheral neuropathy, neutropenia, and infection). All process of the study selection, data extraction, and methodology evaluation will be carried out by 2 authors independently. RevMan 5.3 software will be utilized for statistical analysis. RESULTS: This study will provide a detailed summary of latest evidence related to the effectiveness and safety of bortezomib in combination with chemotherapy in overall survival, progression-free survival, overall response rate, quality of life, and serious adverse events for patients with mantle cell lymphoma CONCLUSION: The findings of this study may provide possible guidance for bortezomib in combination with chemotherapy for patients with mantle cell lymphoma.
