Lentinan je jedan od lekova protiv kancera[3] za koji je pokazano da utiče na odbrambeni imunski sistem domaćina.[4]

Klinička israživanja na obolelima od raka su ukazala na vezu između lentinana i povišenog stepena perživljavanja, poboljšanog kvaliteta života, i umanjene ponovne pojave kancera.[5][6][7][8][9][10][11][12]
