共同的初级终点指标为总生存率和无进展生存率。
Coprimary end points were rates of overall and progression-free survival.
研究人员提到，在两组中总生存期和无进展生存也没有差异。
Overall survival and progression-free survival also did not differ in the two groups, the researchers note.
因此，替代终点如反应率和无进展生存率被普遍接受，尽管各方意识到风险所在。
Thus, surrogate endpoints like response rate and progression-free survival are commonly accepted, although all parties involved realize the risk involved.
