HemOnc vocabulary relationships
The purpose of this page is to describe the existing relationships in the HemOnc ontology and to give examples. Most of the examples are based on adjuvant CapeOx for colon cancer, as described in the XELOXA study's primary publication (Schmoll et al. 2007, JCO).

Further explanation of some relationships
Can be followed by
This directed relationship is phrased as an optional because there is always the possibility, even in a pre-defined protocol, that the patient will not go on to receive the second (or third, etc.) part of a treatment protocol.
Can be preceded by
This directed relationship is phrased as an optional because it is contextual; in many treatment contexts it is not necessary that the first treatment occurs before the second. In some treatment contexts the relationship is absolute, e.g., chemotherapy given in the adjuvant setting must by definition be preceded by a surgical procedure. This subtle distinction is not yet captured by the ontology.
Has been compared to
This non-directional relationship is the pairwise comparison of two regimens in a randomized clinical trial. In the most common scenario one regimen is a control arm and the other is experimental arm, although this is not always the case.
Has FDA indication
With very few exceptions, the FDA approves drugs, not regimens. Currently, all of these relationships in HemOnc are between components (drugs) and conditions.
Has reported endpt
For "negative" studies, which we define as those having p>0.10 regardless of the predeclared level of alpha, the reported endpoint is the primary endpoint. For "positive" studies, the reported endpoint is that which is the least surrogate with a p<0.10.
