Oral cancer is one of the deadliest forms of cancer. The Oral Cancer Foundation estimates that 49,750 Americans will be diagnosed with the disease this year alone. Of this figure, 9,750 will die from the disease. This means that just in the U.S., approximately one person dies of oral cancer every hour.
It's not a lack of treatment that makes oral cancer so deadly. The disease often produces no pain or notable changes during its onset. By the time patients notice, cancer has already metastasized and has progressed to an advanced stage. Moreover, oral cancer has a high risk of growing subsequent primary tumors, which means that a patient is about 20 times at risk of developing a second cancer should they survive their first encounter. The relapse usually happens after five to 10 years.
Danshen is an important medicinal herb in Chinese medicine, particularly as a treatment for both chronic and neoplastic inflammatory diseases. These applications prompted the authors to investigate the effects of red sage extracts on oral cancer cells in both in vivo and in vitro settings.
To investigate the effects of the herb in vitro, they exposed human oral cancer SAS, SCC25, OEC-M1, and KB drug-resistant cell lines to varying concentrations of Danshen extracts. For the in vivo test, the researchers used an oral cancer xenograft mouse model. The action of pro-apoptotic chemicals was examined and their antitumor effects were compared to those of 5-fluorouracil, a common anti-cancer medication.
Analyses revealed that Danshen extract strongly inhibited the proliferation of oral cancer cells (SAS, SCC25, and OEC-M1) by inducing apoptosis through the caspase pathway. The in vivo test showed that Danshen extract was able to suppress the growth of SAS cancer cells and route the resistance of KB drug-resistant cancer cells.
The authors concluded that Danshen extract can be used as a potential anti-cancer agent, especially as a treatment for oral cancer. (Related: Oral Cancer May be Treated with Proanthocyanidins from Medicinal Plants.)
