Required Data Elements

An overarching requirement is that the Knowledge Representation of data elements within the database structures defined match that of the oncological thought processes. In this way, clinical data be fragmented into a database storage schema and then re-constituted without loss of knowledge. This requirement calls for an EPR which has a strong diagnosis/time based approach to data that correctly indicates sequencing and the oncological reasons for events. This thinking is not present in some very widespread Oncology Information Systems (elaboration can be provided if required).

The present and unchanging process of patient management follows the following pattern:


Patient > Consultation > Intent > Modality Selection > Treatment Delivery > Outcome
Unique Identifier
Demographics
  • immutable characteristics
    • birth parameters
      • parents
      • birth place
      • birth date
      • birth place
      • birth gender
  • mutable characteristics
    • occupation
    • residency
    • affiliations
Diagnosis
  • origin site code
  • ontological description of anatomic extent
  • image-based description of anatomic extent
Stage
  • disease extent code
  • ontological description of anatomic extent
  • image-based description of anatomic extent
Prognosis/Risks
  • parameters known to affect disease outcomes
Physiology
  • parameters not known to affect disease outcome
Eligibility/Exclusion
  • parameters that determine eligibility for treatment
  • parameters that determine eligibility for trial inclusion

One of the following words can be assigned to describe the general oncological intent. This is similar to describing my intent in travel - to get from my home to the Empire State Building. It is not "by plane" because no plane leaves from my house or lands at the ESB (well, never again hopefully). It's the following modalities: neoadjuvant drive > neoadjuvant train > neoadjuvant walk > primary plane > adjuvant walk > adjuvant taxi > adjuvant walk.

limited choices
  • radical/curative
  • palliative
  • surveillance

This section results in the selection of a pair of terms - a modality with a descriptor, such as 'primary surgery', or "primary radiotherapy with concurrent chemotherapy" or "primary radiotherapy with neoadjuvant, concurrent and adjuvant hormone therapy"

name of modality
  • surgery
  • radiotherapy
  • chemotherapy
  • hormone therapy
  • biological therapy
modality hierarchy
  • palliative
  • primary
    • single
    • determines timing
      • neoadjuvant (before primary)
      • concurrent (with primary)
      • adjuvant (after primary)

This is a detail section which will vary for each modality, but provide the details of what was undertaken.

surgery
  • operation type
  • operator
  • pre-op R assessment
  • post-op R assessment
radiotherapy
  • prescription
  • plan
  • treatment delivered
chemotherapy
  • regimen
  • cycles delivered
hormone therapy
  • drug
On treatment Effects
  • Acute Side effects
  • Complications
  • Disease Response
Post Treatment Effects
  • Late Effects
  • Dysfunction Assessment
  • Disease Status



Demographics
  • need a way to use demographics to produce a unique ID to produce anonymous records if transferred
Diagnosis
  • utilizing a structure which is mapped (via UMLS)
    • PRESENT
      • using ICD .... 9 (USA) 10 (AU, NZ, UK?)
      • predominantly for malignant diagnosis alone
      • already includes structured morphology nomenclature (e.g. SNOMED
    • FUTURE
      • include all benign diagnoses (these are likely to be be transferrable from other specialties and GPs)
      • expanded morphology descriptors that include immunohistochemical patterns, genetic changes
Stage
  • utilizing a structure which is mapped (via UMLS)
    • PRESENT
      • use AJCC/UICC
    • FUTURE
      • utilizing more specific anatomical definitions
Intent of Oncological Plan
  • PRESENT
    • always determined implicitly
  • FUTURE
    • always stated explicitly
Employed Modalities
  • PRESENT
    • usually able to be determined from reading a narrative
    • formal notation usually only determined for one's own modality
    • confusion of descriptors with intent
    • variable language describing intent
  • FUTURE
    • explicit description of all other modalities and their descriptors
    • determined after intent quantified
    • standardised nomenclature for descriptors
Modality Details
  • PRESENT
    • encapsulated within DICOM-RT
    • no accepted specification for chemotherapy
  • FUTURE
    • DICOM-RT housed in PACS with viewing capabilities
    • Common chemotherapy specification

Establishment of Iterative Disease Management Loop

These Loops will determine how events such as recurrence will be coded and what subsequent data will be supplied. This is exactly the same sequence as occurs initially, except that the loop is not 'completed' until an outcome assessment is finished. If the assessment is that there is recurrent disease then the loop is re-entered and diagnosis reviewed, re-staging (using the same coding structures as the first time) and re-assessment for intent and modality is undertaken.
