Aspirin is a kind of nonsteroidal anti-inflammatory drugs. It is the first hint of aspirin's potential role in tumor prevention and treatment when Gasic found that tumor metastasis is reduced in thrombocytopenia mice, and then the research confirmed that aspirin treatment can significantly reduce the tumor metastasis. In recent years, a lot of epidemiological evidence and clinical trials found that aspirin played an important role in cancer prevention, at the same time, more experimental study has found that it can also play a role in tumor treatment. Our previous animal experiments found that a combination of sorafenib and aspirin can reverse the negative effect of sorafenib which promoted tumor metastasis, and obviously prolong survival of a tumor-burdened nude mice.
