The rfHSA is used for treating cancer or a tumor in a subject in need thereof The rfHSA may also be used as a reagent for detecting the presence of a cancer cell associated with integrin β1 or serine/threonine protein kinase Akt and extracellular signal-regulated kinase 1/2 (ERK1/2) in a tumor sample or as a reagent for inhibiting phosphorylation of Akt and ERK 1/2 in a cancer cell sample. A cell lysate of a cancer cell treated with rfHSA, a vaccine composition comprising the cancer cell lysate, and use thereof are also disclosed. Also disclosed is a method tor preparing rfHSA.
