CDR Tickets

Issue

The term documents Cancer.gov receive for the drug dictionary have the following sentences added to each definition:

Check for <a class="navigation-dark-red" href="https://www.cancer.gov/about-cancer/treatment/clinical-trials/intervention/C26449\">active clinical trials</a> using this agent. (<a class="navigation-dark-red" href="https://ncit.nci.nih.gov/ncitbrowser/ConceptReport.jsp?dictionary=NCI%20Thesaurus&code=C26449\">NCI Thesaurus</a>)

This causes a number of issues:

• Links are generated for 0 trials. We should not generate links for 0 trials.

• For short definitions the text is appearing in the meta description of pages.

• The text element within the Cancer.gov dictionary record does not contain HTML and thus it just has the text, "Check for active clinical trials using this agent. (NCI Thesaurus)" 

Request

If the CDR were to expose the NCT ID (C-code) as a data element on the record, the dictionary code could easily generate those two links. As it would be generating the links, the text would not appear in the metadata. Additionally, we would then have the flexibility to query the API to check if there are any Clinical Trials before rendering the active trials link.

I leave it to ~bkline and/or ~volker to identify an appropriate place to add the NCT ID in the XML. In the Cancer.gov dictionary service JSON structure for the API, there should be a `nctid` element as a sibling to the `id` element. e.g

{
  "id": "37783",
  "nctid": "C1681",
  "term": "alemtuzumab",
  "alias": [
    {
      "name": "anti-CD52 monoclonal antibody",
      "type": "Synonym"
    },
    ...SNIP...
  ],
  ...SNIP...
}
