Introduction: Lymphomas are a heterogeneous group of malignant neoplasms originating from the lymphoid lineage, they are classified into two groups: Hodgkin´s lymphoma and non-Hodgkin’s lymphoma (NHL), the neoplasm has a multifactorial origin, involving states of immunosuppression and constant stimulation of the immune system. It is important to comprehend the role of the complement system since it acts as the first line of defense of the immune system. Objective: Describe the relationship between Non-Hodgkin Lymphoma and the complement system. Methods: This literature review adopts a systematic approach to non-Hodgkin’s lymphoma and the complement system; Databases: PubMed; the search was restricted to peer- reviewed articles published between 2020 - 2025 written in English. Conclusion: Complement system involvement in NHL is complex, with both pro-tumor and anti-tumor effects depending on the specific component and the context. Further research is needed to explore the potential of targeting the complement system for improved NHL treatment.
