ASCO and pharmacometrics

Dear all, I have a question and appreciate it if somebody can answer to me. We had submitted an abstract to ASCO annual meeting presentation 2016, and its contents included a pharmacometrics work of quantitative safety profile analysis of an anticancer drug. The behave of the safety index time courses is very unique and its results showed a very high usefulness of this drug. The abstract also included the table of population PK/PD parameters that expressed its nature, and it was compared with the similar older drug safety profile and demonstrated very high safer profile quantitatively. I have some experiences to publish some articles of population PK/PD work in several clinical pharmacology journals in the past, and I was so confident for just a poster presentation in ASCO. However, the judgment was “publication only”, i.e. just presentation in online but no poster presentation and no official record of publication officially. So, my question is whether pharmacometrics work is difficult to be picked up in ASCO presentation. Or, was my work evaluated to have no worth to be presented even in poster session because the pharmacometrics works presented in ASCO are having very high level? I have never visited ASCO before, and I just want to hear opinions about how much of importance is considered for pharmacometrics work in ASCO. Thanks a lot in advance for your comments/thoughts.
