I disagree that the title "hides" that the title was small and that it disappeared for two weeks. The surviving contingent on the E. americana strain was evaluated for 60 days, and the tumor doesn't look particularly small based on the picture on page 8 of the paper. I think the study size is small (n=5) so we'd like to see more large-scale studies next, but it's already a strong result to show 5/5 (100%) at p < 0.0001 for multiple primary endpoints and the absence of success from comparable bacteria is helpful to frame future research. The absence of long-term side effects and only transient weight-loss followed by 15-day weight gain is also intriguing. I'm not a doctor, oncologist, or cancer researcher, but the methodology looks sound and appropriate to me, as does the title, based on reading the paper.
