Lentinan has been shown to have a suppressive effect on the natural pulmonary metastasis of Lewis lung carcinoma, though its effect seems to depend on the timing of the administration. Administration of lentinan after the amputation of tumor was found to be more effective than before administration. Additionally, lentinan also has shown a marked suppressive effect on the pulmonary metastasis of MC-CS-1 fibrosarcoma, a high sensitive tumor for lentinan in any administration examined. These date suggest the usefulness of lentinan in suppressing tumor metastasis.

The most important target in pharmaceutical therapy against cancer is complete suppression of metastases and recurrence after curative surgical operation. It is fundamentally, a growth inhibition and regression of small number of autochthonous tumors scattering in the host, and coexistence between tumor and host is also important. As immunosuppressive anticancer drugs have detrimental effects for patients in such cases, application of strong immunopotentiators such as lentinan should be expected. Lentinan showed a prominent effect on suppression of metastases in experimental systems of clinical models using MH-134 hepatoma, Madison-109 lung carcinoma and DBA/2.MC.CS-1 fibrosarcoma. Suppression of carcinogenesis may be considered as one of experimental methods to prevent metastases in a viewpoint of regression of small number of autochthonous tumor cells. Lentinan given at suitable timing and schedule showed marked prophylactic effect on chemical and viral carcinogenesis. Mode of action of lentinan as T-oriented adjuvant in its antitumor and metastases-inhibitory effects is also discussed. Considering excellent end-point results of Phase III with advanced and recurrent gastrointestinal cancer, lentinan is the most hopeful substance to prevent micrometastases.
