Searching for Biomarkers in caDSR

The search feature enables you to search for biomarkers listed in caDSR. You can search for biomarkers by the following criteria:

• Search Term. Search for biomarkers meanings that contain the search term
• Search Scope. Search for biomarkers that contain the search term in their preferred permissible values only, in their synonyms (alternate names) only, or in both (the default).
  
• Public ID. Search for biomarkers by their Public IDs only
  

Additional search options include the following:

• Case-sensitivity. You can elect to make the search term case-sensitive or insensitive. Searches are case-insensitive by default.
• Highlighting search terms. Query text in search results is highlighted by default to make search terms easier to identify. You can turn on or off query text highlighting in the search results.

Most search results list primary terms followed by all possible synonyms in parenthesis in the following order:

• Exact matches for the Primary term
• Matches that contain the search term alone (i.e., the term is not part of a larger term)
• All other matches that contain the search term

How to Search for Markers in caDSR

1. Follow Steps 1 and 2 in Adding Biomarkers.
2. Next to the Name field, click caDSR
   The Marker Search in caDSR window appears.
   

3. Enter all or part of the criteria for the search in the fields provided.

4. To restrict your search by case, next to Case-Sensitive Search, select Yes (the default is case-insensitive).

5. To highlight the term you searched for in the list of results, next to Highlight Query Text, select Yes.

6. Press the ENTER key on your keyboard, or click Search.

7. The results of your search are listed in a table with their permissible values ² .
   

8. In the row that contains the appropriate marker, click Select.
   You are returned to the Add Marker page. The Marker Name field is populated with information from the marker you selected.

Adding Biomarkers from HUGO to the caDSR Database

If you did not find a given biomarker in caDSR, The Research Scientist must review the term to determine if a request must be sent to caDSR. If the marker is a gene, the Research Scientist should access HUGO (via the link in the request form). The HGNC-approved symbol should be requested as the primary term, followed by any appropriate synonym from the protocol in parenthesis. The HGNC ID number should also be included in the request after selecting the Found in Hugo? check box.

How to Request Markers from HUGO for Addition to the caDSR Database

1. Follow Steps 1 and 2 in Adding Biomarkers.
2. Next to the Name field, click caDSR
   The Marker Search in caDSR window appears.
   
3. Click Create Biomarker Request.

4. Select the Found in HUGO? check box, and then click the HUGO link.
   The window displays a new field for the HUGO marker code, and the HGNC database is launched in a new browser window.
5. Search for the marker in the HGNC database, and then enter the HGNC ID number for the appropriate record into the Hugo Marker Code field. This field is displayed only when you select the Found in HUGO? check box.
6. In the Text of marker as written in the protocol field, copy and paste, or enter, the information about the marker as it appears in the protocol.
7. Click Send Email.
   Your request is sent to the caDSR for processing. The value you requested is listed on the Pending Markers Report with the Pending status. You can return to the Pending Markers report later to enter the Public ID number once caDSR has sent notification to the Research Scientist that the new term was created.

Managing Intervention Terms

You can import NCIt terms on demand if the term you require for abstraction does not exist in the CTRP database. Once imported, CTRP syncs the term with in the NCIt database automatically.

If a term does not exist (i.e., has not been published yet) in the NCIt, you can request the term directly from EVS. Once EVS curators have responded to your request, you can enter new term details when abstracting trials. Later EVS publishes the new term in the NCIt. Refer to Managing Disease and Intervention Terminologies.

How to Manage NCIt Intervention Terminology

1. At the bottom of the Interventions page, click Manage NCIt Terms.
   The Manage NCIt Terms menu contains options for managing intervention terms.

In interventional studies, an arm is a group of study subjects associated with a given treatment assignment. Arm information is required for Complete trials, and is optional for Abbreviated trials.

When adding arms to a trial, you assign to them the interventions currently abstracted for the trial.

The following rules apply to each trial:

• There must be at least one arm/group that implies that the entire study subject population receives the same intervention.

• The number of arms/groups added to the trial must coincide with the number indicated in the trial’s Design Details. See Abstracting Interventional Trial Design Details.

• Every arm must have at least one assigned intervention (except for the arm type "no intervention").
• Every intervention must be assigned to at least one arm.
• There must be only one arm with the same combination of description and associated intervention.
• Arm details for single-arm trials are not required.

Trials can have multiple arm records. Each record displays the following arm information:

Group/cohort information pertains to Complete non-interventional trials only. In non-interventional studies, cohorts are groups of individuals, initially defined and composed, with common characteristics (e.g., condition, birth year), who are examined or traced over a given time period.

When adding groups to a trial, you assign to them the interventions currently abstracted for the trial.

The following rules apply to each trial:

• There must be at least one group/cohort that implies that the entire study subject population receives the same intervention.
