Abstract: Lentinan (LNT) is a naturally occurring polysaccharide extracted from the fruiting body of Lentinula edodes (Shiitake), a fungus belonging to the phylum Basidiomycota, widely cultivated and consumed in Asia. This β-glucan compound has demonstrated a broad spectrum of biological effects, including antitumor, anti-inflammatory, and antioxidant properties. These characteristics position LNT as a promising therapeutic candidate for cancer patients, particularly in the face of the growing incidence of cancer, especially lung cancer, where LNT has shown notable efficacy. The search for effective bioactive compounds, particularly those of natural origin, has intensified. In this context, LNT has emerged as a competent agent, especially in combined therapy. Its association with chemotherapy has shown synergy, potentiating the therapeutic response, improving patient prognosis, strengthening the host's immune response, and mitigating the adverse effects frequently associated with chemotherapeutic drugs. The therapeutic use of Lentinan is already an established clinical practice in Asian countries such as Japan and China. This qualitative and descriptive literature review, based on data from the National Center for Biotechnology Information (NCBI) and PubMed Central (PMC), aims to elucidate the therapeutic mechanism of LNT and its impact on cancer prognosis. LNT does not exert a direct cytotoxic effect on tumor cells. Instead, its mechanism of action is primarily immunomodulatory. The compound indirectly regulates tumor growth by inhibiting inflammatory pathways, such as the expression of IL-6 and IL-1β. Additionally, Lentinan promotes the infiltration of effector immune cells into the tumor microenvironment, including CD4+, CD8+, Natural Killer (NK) cells, and monocytes, reinforcing the host's immunological surveillance against neoplastic cells.
