Abstract | BACKGROUND AND PURPOSE: MATERIAL AND METHODS: Two HNSCC cell lines, SCC9 and SCC25, were treated with increasing doses of betulinic acid and sequentially irradiated with a single boost of 4 Gy from a conventional radiation source. The cells were counted, the surviving fraction was determined, and colony-forming assays were performed. RESULTS: It could be shown that betulinic acid alone inhibits cell survival, affects cell survival additively in combination with irradiation and decreases clonogenic survival in both cell lines when applied alone. CONCLUSION:
