Christine’s poster, titled “Can Frequency of Prostate Biopsy on Active Surveillance Be Reduced Without Significantly Increasing Risk?,” was recognized in the “active surveillance” session.

Active surveillance (AS) for prostate cancer (CaP) involves close follow-up with serial prostate biopsies. The optimal biopsy frequency during follow-up has not been determined, resulting in variation in practice. The goal of this investigation was to use longitudinal AS biopsy data to assess if the frequency of biopsy could be reduced without substantially prolonging the time to detection of Gleason ≥ 7 disease. The research highlighted in the poster found that, while annual biopsy for low-risk men on AS is associated with the shortest time to detection of Gleason ≥ 7 disease, several alternative strategies may allow for less frequent biopsy without sizable increases in time to detecting grade progression.

The electrons absorb laser light and set up “momentum combs” (the hills) spanning the energy valleys within the material (the red line). When the electrons have an energy allowed by the quantum mechanical structure of the material—and also touch the edge of the valley—they emit light. This is why some teeth of the combs are bright and some are dark. By measuring the emitted light and precisely locating its source, the research mapped out the energy valleys in a 2D crystal of tungsten diselenide.

Mapping quantum structures with light to unlock their capabilities

Rather than installing new “2D” semiconductors in devices to see what they can do, this new method puts them through their paces with lasers and light detectors. | Medium Read
