Diagnosis Model in HL7 V3

Summary

Diagnoses represented in HL7 V3 shall useu the class Observation, which is modelled as shown in fig. 1.

Detailed descriptions of classes and data types in this model can be found in the related HL7 V3 documentation and Data Type Guidelines.

The following sections specifiy how diagnosis attributes shall be mapped into the Observation model.

Plain Text

value.originalText diagnosis as a plain text ST[0..1] Plain text descriptions of the specific diagnosis shall be stored in the subelement originalText of element value. If it is not necessary to specify a text or should this text not be available, the @nullFlavour attribute shall be used. This element shall explain the reason why there is no plain text. A value of "NAV" states that no coded text is available (yet). More values are described in the HL7 documentation.

The attribute @language of subelement originalText may be used to specify the language of the prosaic diagnosis text.

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <value xsi:type="CD" nullFlavor="NAV">
      <originalText>Rektumkarzinom mit Höhenlokalisation ab Anokutanlinie/Linea dentata
      </originalText>
    </value>
  </observation>

Diagnosis Code and Text

value Diagnosis Code CD[0..1] Representing a diagnosis via a code and its associated text shall be done va the value element (in the model: an attribute of the Observation class).

The XML attribute @code shall store the diagnosis code and @displayname shal store the associated diagnosis text.

Such a structured representation of e.g. an ICD10 coded diagnosis looks like this:

The XML attribute @codeSystem shall store the OID for the specific ICD-10-GM version being used and the @codeSystemName attribute shall store the plain text name of the coding system and version.

  <!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
  ...
    <!-- ICD-Code of a diagnosis -->
    <value xsi:type="CD" code="I01.0"
      displayName="Akute rheumatische Perikarditis"
      codeSystem="1.2.276.0.76.5.311" codeSystemName="icd10gm2006"/>
    ...
  </observation>

Diagnosis Type

code classification code CD CW[1..1] The XML attribute shall specifiy the classification code using the attribute @codeSystem for storing the OID of that coding system (also see Annex <10>)

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
     <code code="DX" codeSystem="1.2.276.0.76.5.342"/>
     ...
  </observation>

Diagnosis Date

author.time Diagnosis Date IVL<TS>[0..1] The diagnsis date shall specify when the diagnosis was made as the time in the clinical process which is not necessarily the documentation date. The diagnosis date shall be represented using the author instance which shall be connected via Participation to the current Observation instance. Instances of author contain a model attribute time of type IVL<TS>. Detailed information regarding the person giving the diagnosis shall be modelled using an instance of assignedEntity.

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <author>
      <!-- Diagnosedatum -->
      <time value="20100111"/>
      <assignedAuthor>
        ...
      </assignedAuthor>
    </author>
    ...
  </observation>

Documentation Date

dataEnterer.time documentation date TS [1..1]

The documentation is the date when the diagnosis has been entered by e.g. a clinician. The data value is mapped to an instance dataEnterer which is related via a Particpation to the Observation instance (see fig. 1 Observation Model).

The dataEnterer class has an model attribute time of type TS, such that in XML the data value will be mapped into an element time and an XML attribute @value.

In case there is no dataEnterer instance, the participation relation with its model attribute typeCode=ENT also manages a participationRole instance representing the data entering person that would otherwise be modelled through a instance of dataEnterer.

<!-- structured representation of diagnosis -->
  <observation classCode="OBS" moodCode="EVN" negationInd="true">
  ...
  <!-- documentation date -->
    <participant typeCode="ENT">
      <time value="20060606"/>
      <participantRole>
        ...
      </participantRole>
    </participant>
    ...
  </observation>

Diagnosis Time Interval

effectiveTime diagnosis time interval IVL<TS>[0..1]

The model attribute effectiveTime of class Observation specifies the time interval for which the specified is (or, has been) clinically relevant.

In XML, the sub-element low shall specify the begin data and sub-element high shall specifiy the end date. Dates for low or high may also be specified without the other.

<!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <effectiveTime>
       <low value="20050127"/>
    </effectiveTime>
    ...
    </observation>

Diagnosis Confidence

value.qualifier diagnosis confidence CR [0..1]

the diagnosis confidence shall be represented in the model attribute value using a sub-element qualifier.

   <!-- structured representation of diagnosis -->
  <observation moodCode="EVN" classCode="OBS">
    ...
    <value xsi:type="CD" nullFlavor="NI">

      </qualifier>
    </value>
  </observation>

XML attribut @code in name shall specify the name of the diagnosis confidence qualifier, based on the table given below. XML attribut @codeSystem shall specify the OID of the system giving these qualifier names. The diagnosis confidence shall be specified using XML attribute @code in the XML element value.

For out-patient care (§ 295 SGB V, Germany) diagnosis confidence attributes are mandatory, while for in-patient care (§ 301 SGB V) they are forbidden i.e. must not be specified. (Source: DIMDI)

Representation of Diagnosis in specific Codesystems

ICD-10-GM-coded Diagnoses

Mapping of ICD-10-coded Diagnoses into HL7 v3

Structured representations of ICD10-encoded diagnoses must support primary and secondary codes, code extensions, side localizations and confidence. The primary code represents the main disease. The secondary code extends the primary code and is either used to describe manifestations in organs ("asterisk") or the cause (etiology, e.g. which bacteria) of the main disease ("exclamation") In order to represent this dependency, an additional oberservation instance will be connected via the ActRelationship to that Observation instance containing the primary code.

So we have the following basic structure for ICD10-encoded diagnoses:

Datei:Figure2.jpg Figure 2: Class Diagram of ICD-10 Diagnoses in HL7 v3

The attribute typeCode in the ActRelationship shall represent the code extension

The related Observation instance (connected via the ActRelationship) has MFST (Manifestation) as its typeCode in order to represent 'asterisk"-codes.

Exclamation-Code extensions are being represented as Observation instances connected via ActRelationships with typeCode CAUS (Cause).

The resulting XML structure of an ICD-10 encodeded diagnosis looks like this:

<!-- Structured Representation of Diagnosis-->
   <observation moodCode="EVN" classCode="OBS">
      …
      <!-- Primary Code-->
      <value xsi:type="CD" code=" E14.30" codeSystem=" 1.2.276.0.76.5.311"/>
      <entryRelationship typeCode="MFST">
         <observation moodCode="EVN" classCode="OBS">
         …
            <!-- Secondary Code-->
            <value xsi:type="CD" code=" H28.0" codeSystem=" 1.2.276.0.76.5.311"/>
         </observation>
      </entryRelationship>
   </observation>

In this case the containing ActRelationship instance is of class entryRelationship- repesented by an element of that name.

Attribute @typeCode has MFST as a fixed value for representing an asterisk code.

value.@code ICD-Code ST [1..1] XML-Attribute @code shall store the specific ICD-10 Code.

value.@codeSystem OID of ICD-Codeset UID [1..1] XML-Attribute @codeSystem shall keep the OID of the ICD-10 Version being used. The appendix gives hints towards versions being used in practice.

value.@codeSystemName Name of ICD-10 Version ST [0..1] XML-Attribute @codeSystemName may store the Name of the used ICD-10 Version.

value.@displayName ICD-Code Text ST [0..1] XML-Attribute @displayName may store the verbose text of the ICD-Code.

OIDs and names of ICD-10 versions may be obtained from DIMDI (www.dimdi.de)

Representation of Side Localisation

value.qualifier Side Localisation CR [0..1]

The side localisation code shall be represented using the child element qualifier of the value element, as it refines the specification of that diagnosis code (as decided by HL7 DE TC meeting on 2005-09-01, minutes item 1.3.2).

An example representation looks like this:

<!-- Structured Representation of a Diagnosis -->
   <observation moodCode="EVN" classCode="OBS">
      <code code="DX" codeSystem=""/>
      <!-- Primary code-->
      <value xsi:type="CD" code="E14.30" codeSystem="1.2.276.0.76.5.311">
         <qualifier>
            <name code="7" codeSystem="2.16.840.1.113883.3.7.1.0"/>
            <value code="L" codeSystem="2.16.840.1.113883.3.7.1.7"/>
         </qualifier>
      </value>
      <entryRelationship typeCode="CAUS">
         <observation moodCode="EVN" classCode="OBS">
            <code/>
            <!-- Sekundary code-->
            <value xsi:type="CD" code="H28.0" codeSystem="1.2.276.0.76.5.311">
               <qualifier>
                  <name code="7" codeSystem="2.16.840.1.113883.3.7.1.0"/>
                  <value code="B" codeSystem="2.16.840.1.113883.3.7.1.7"/>
               </qualifier>
            </value>
         </observation>
      </entryRelationship>
   </observation>

Child element 'name' within element 'qualifier' defines the type of qualifier.

Therefore, in order to express a qualifier for side localisation, the fixed value „7“ from code system OID 2.16.840.1.113883.3.7.1.0 shall be used:

   <qualifier>
      <name code="7" codeSystem="2.16.840.1.113883.3.7.1.0"/>
      <value code="L" codeSystem="2.16.840.1.113883.3.7.1.7"/>
   </qualifier>

Representation of Diagnosis Confidence

value.qualifier Diagnosis Confidence CR [0..1]

The Diagnosis Confidence can be considered an extension to the ICD-10 code, shall be represented by the child element qualifier of the value element.

<!-- Structured Representation of a diagnosis-->
   <observation moodCode="EVN" classCode="OBS">
      <code code="" codeSystem=""/>
      <!-- Primary code-->
      <value xsi:type="CD" code="E14.30" codeSystem="1.2.276.0.76.5.311">
         <qualifier>
            <name code="8" codeSystem="2.16.840.1.113883.3.7.1.0"/>
            <value code="G" codeSystem="2.16.840.1.113883.3.7.1.8"/>
         </qualifier>
      </value>
      <entryRelationship typeCode="CAUS">
         <observation moodCode="EVN" classCode="OBS" negationInd="true">
            <code/>
            <!-- Secondary code-->
            <value xsi:type="CD" code="H28.0" codeSystem="1.2.276.0.76.5.311">
               <qualifier>
                  <name code="8" codeSystem="2.16.840.1.113883.3.7.1.0"/>
                  <value code="A" codeSystem="2.16.840.1.113883.3.7.1.8"/>
               </qualifier>
            </value>
         </observation>
      </entryRelationship>
   </observation>

Child element 'name' within element 'qualifier' defines the type of qualifier.

Therefore, in order to express a qualifier for diagnosis confidence, the fixed value '8' from code system OID 2.16.840.1.113883.3.7.1.0 shall be used:

Child element 'value' within 'qualifier shall store the respective confidence value.

Possible values are listed in Table 2.

   <observation classCode="OBS" moodCode="EVN">
      ...
      <value xsi:type="CD" code="A25.1" codeSystem="1.2.276.0.76.5.311" codeSystemName="icd10gm2006">
         <qualifier>
            <name code="8" codeSystem="2.16.840.1.113883.3.7.1.0"/>
            <value code="G" codeSystem="2.16.840.1.113883.3.7.1.8"/>
         </qualifier>
      </value>
   </observation>

When representing an EXCLUDED diagnosis the attribute @negationInd shall be specified as „true“.

Specifying a Diagnosis using a Thesaurus Index

One more way of specifying a diagnosis is by using an index referring to an entry in a medical thesaurus.

Example: Mapping an Alpha-ID-coded Diagnosis

As an example, the diagnostic thesaurus „Alphabetische Verzeichnis zur ICD-10 GM“ (alphabetic directory of ICD-10 GM) is being used in Germany.

This directory allows to locate a verbose description of ICD-10 terms and to find the corresponding ICD-10 GM code.

The so-called Alpha-ID has been developed to process entries of that alphabetic directory.

It is an identification number for each textual entry in the "alphabetic directory".

In order to find this alpha-ID, a mapping file has been provided by DIMDI (www.dimdi.de).

The Alpha-ID is needed because in medical documentation, the descriptions of diagnoses need to be more differentiated than what ICD-10 codes actually can express.

Using the alpha-ID allows for a much finer granularity of diagnosis descriptions.[DIMDI,Alpha_Id].

As an example the ICD-10 Code “A01.0 Typhus caused by Salmonella typhi“ encodes multiple diagnoses such as „liver typhus“, „lung typhus“ and many more.

By using the Alpha-Id it is possible to specify the specific type of typhus, like e.g. „liver typhus“ as„I18721“ and „lung typhus“ as „I21312“.

Figure 3: Excerpt from mapping file „icd10gm2009_alphaid_edv_ascii20081006.txt“

Figure 4 shows an excerpt of the metafile which defines the fields of the mapping file for the Alpha-Id.

Each record consists of six fields, each being separated by a semicolon.

The fields in each record contain the following data:

  Field 1: Validity (0-not valid, 1-valid)
  Field 2: Stable Identification with prefix I or T ("Alpha-Identifikationsnummer")
  Field 3: Primary key (with cross)
  Field 4: Asterisk key (with asterisk)
  Field 5: Additional key (with exclamation)
  Field 6: Related text

Figure 4: Excerpt from Alpha-ID metafile „icd10gm_alphaid_edv_ascii_liesmich.txt“

A structured representation of a thesaurus uses the @value attribute of class Observation and an example instance lloks like this:

   <observation moodCode="EVN" classCode="OBS">
   …
   <value xsi:type="CD" code="I2173" codeSystem="1.2.276.0.76.5.309" codeSystemName="alphaid2006"/>
   ...
   </observation>

value.@code Alpha-Id ST [1..1] XML-Attribute @code stores the index referring to an enty in the „Alphabetisches Verzeichnis“

value.@codeSystem OID ofAlpha-ID UID [1..1] XML-Attribute @codeSystem stores the OID of the Alpha-ID Version being used.

value.@displayName Alpha-Id Text ST [0..1] XML-Attribute @displayName may be used to display a text related to the current Alpha-Id

value.@codeSystemName Name of Alpha-ID Version ST [0..1] XML-Attribut @codeSystemName represents the Name of the coding system, in our case alphaid2006.

OID and name of ICD-10 Version can be obtained from DIMDI (www.dimdi.de)

Diagnosis Specification using Identifiers in a Nomenclature

One way of specififying a diagnosis is to use the code representing a diagnostic term in some medical nomenclature.

A well-known nomenclature in medicine is SNOMED-CT ("systematic nomenclature of medicine - clinical terms")

Compared to ICD-10 it has more concepts for diagnoses and mostly does not classify.

In general using a term of a nomenclature often preserves more information than using a term of a classification.

Classification is selecting a common representation for a set of concepts that are (under some aspect) considered similar.

As a result, classification reduces information, which is demonstrated by the following examples

I.e. as a part of clinical documentation of diagnosis the encoding using alpha-id or some identifier in a nomenclature would be preferred over using a classification like e.g. ICD-10.

The example shows concepts all being represented through the same ICD-10 code Q92.8 for 'Other specified trisomies and partial trisomies of autosomes'.

A simple comparison of codes from nomenclatures gives an example of missing clarity and precision of the ICD-10 classification.

Diagnosis	ICD-10 Code	Alpha-ID	Snomed CT	ID MACS
Imbalanced Insertion	Q92.8	I87548	254262003	M002405-D62839-58
Trisomy 22	Q92.8	I81282	205655003	M001897-D55549-58
Trisomy 20	Q92.8	I81283	53346000	M002406-D55530-58
Partial Trisomy a.n.k.	Q92.8	I81284	133849008	M001D1C-C78409-58

Table 6: Diagnoses in different coding systems

Precoordinated and Postcoordinated Concepts of a Nomenclature

For specifiying a diagnosis using a terminology there are two fundamental approaches:

The pre-coordinated approach selects a fixed term among a comprehensive list with representations for all possible concepts.

The list of all pre-coordinated terms limits the set of concepts which can be represented.

The post-coordinated approach constructs each term out of (more or less independently) encoded aspects of the concept to be represented.

The resulting term is the combination of the encoded aspects of the given concept.

ICD-10 is a good example of a pre-coordinated terminology, as it lists all the terms for the concepts it can represent.

The cross-asterisk extension to ICD-10 is an example of post-coordination.

More info can be found under the Terminfo project [Terminfo] of HL7 International.

Diagnosis by Thesaurus Index or Term within a Nomenclature

A term in a nomenclature is specified through the @value attribute of class Observation.

An example (SNOMED CT) of the structured representation looks like this:

   <observation moodCode="EVN" classCode="OBS">
   ...
   <value 
      xsi:type="CD" code="314888007" 
      codeSystem="2.16.840.1.113883.6.96"
      codeSystemName="SNOMED CT"
      displayName="Typ-II-Diabetes with diabetic cataract"/>
   ...
   </observation>

Attribute value.@code Index or Term in Nomenclature

CD CWE [1..1] The XML attribute @code keeps the index referring to an entry in a thesaurus or nomenclature.

Attribute value.@codeSystem OID of Nomenclature

UID [1..1] The XML attribute @codeSystem stores the OID of the thesaurus or nomenclature.

Attribute value.@displayName Text

ST [0..1] Through the XML attribute @displayName a plain text related to the index can be given.

Attribute value.@codeSystemName Name of Nomenclature

[0..1] The XML attribut @codeSystemName describes the name of the thesausrus or nomenclature.

Representation of Cancer Diagnosis

Introduction

In this chapter, diagnostic aspects of documentation of tumor diseases will be described. Different aspects of diagnostical descriptions of tumor diseases are described by ICD-O (Oncology) and by further classifications to document the expansion (tumor spread) or diseases stage, respectively, the latter one mostly being classified by the TNM-System.

Especially for hemato oncological diseases (Leukemias and Lymphomas), other systems (e.g. Ann-Arbor-Classification) are used. TNM-System discribes:

• Expansion of primary tumor (extent or, spread in distant organs repectively)
• Affection of lymph nodes in lymph flow area
• Existence of distant metastases.

For non-TNM–-classifiable diseases or in addition to the TNM-System there are a number of further classification systems:

• Ann Arbor
• Rai
• Binet
• CML-Phasen
• FAB
• Durie and Salmon
• Gleason-Score

Discriptions can be found here: http://www.med.uni-giessen.de/akkk/gtds/grafisch/doku/bd5f.htm http://www.tumorzentren.de/tl_files/dokumente/adt_basis.pdf

This list probably will be always incomplete because of the medical progress.

Third Edition of ICD-O [DIMDI, WHO] is the topical one. ICD-O consists of two axes, Topography- and Morphology-Axis. In ICD-O, tumor can be classified by

• Site
• Tissue Structure (Histology)
• Biological behaviour (Dignity)
• Tissue grading (mostly in two or four stages)

In this case, tissue structure and tissue grading is redundant. Precisely: The first four digits of morphology-code describe tissue-type. The fifth one describes biological behaviour (dignity-code):

• /0 = benign
• /1 = neoplasm with uncertain or unknown behaviour
• /2 = Cancer in situ
• /3 = malignant, primary tumor
• /6 = malignant, metastasis (not used in tumor documentation)
• /9 = malignant, uncertain wether primary tumor or a metastatic

The sixth digit describes grading, differentiation or phenotype (Histology/Pathology):

• 1 = Grade I, well differentiated (Low grade)
• 2 = Grade II, moderately differentiated (Intermediate grade)
• 3 = Grade III, poorly differentiated (High grade)
• 4 = Grade IV, undifferentiated (High grade)
• 9 = Grade IX, grade cannot be assessed

For Leukemias and Lymphomas, the sixth digit signifies the immunophenotype

• 5 = T-Cell
• 6 = B-Cell, Pre-B-Cell, B-Ancestor-Cell
• 7 = Null-Cell, Not-T-Cell-Not-B-Cell
• 8 = NK-Cell, Natural Killer Cell
• 9 = Determination of Cell Type was not accomplished, not specified or not applicable

TNM System describes

• Expansion of primary tumor (extent repectivly spread in distant organs)
• Affection of lymph nodes in lymph flow area
• Exisistence of distant metastasis

For the topography axis, there exists an (hierarchical) enlargement, the ‘localisation key’ (Wagner, G. (HRSG.): Tumorlokalisationsschlüssel, 5. Auflage, Springer Verlag, Berlin, Heidelberg, New York, Tokyo 1993), which can supply at some positions clinical relevant differentiation. The morphology axis is composed of a four-digit code for tissue basic structure, a characteristic number for dignity and an additional grading item. The key itself does not contain all possible combinations of histology and dignity, but points out those ones, for whome exist special discriptions. Vice versa not all combinations of basic structure and dignity are possible (so there is no ‘benign leukemia’). Not either there is a grading system available for all kinds of tumor. For some ones, additional information (for Example ‘Cell-line’) is used at the corresponding position.

Tumor Localization

For Tumor-Coding first of all, the site is important. It will be classified by the Topography -Axis of ICD-O. Topographical -Codes of ICD-10 are based on chapter II (Neoplasm –C 00 – C 97) of ICD-10. However, some of the topographical Codes of ICD-10 (Codes) are not used, because their content is discribed by histology- and digit-Codes of ICD-O. (e.g. Differentiation in situ/ infiltrated, melanoma vs. scin cancer).

Tumor Histology and Dignity

Furthermore, in ICD-O, tumor morphology i.e. tissue structure (histology) and biological behavior (dignity) is discribed by special Codes. Tumor histology is coded by a four-digit number, which is assumed of the morphology-axis of Standardized Nomenclature of Patholoy (SNOP). Dignity-Code is attendant on morphology-Code, seperated by /. Examples:

• 8060/0 squamous epithelium - papillomatose
• 8070/2 squamous epithelium – cancer in situ undifferentiated
• 8070/3 squamous epithelium – cancer undifferentiated
• 8070/6 squamous epithelium – cancer metastasis undifferentiated

Tumor Grading

Grading is derived from the comparison of primary tissue with the neoplasm of this tissue. There are five grading-degrees (s.o.) and further three degrees for Malignant Lymphoma. Registration of tumor grading is also provided in TNM.

Qualifier of Tumor Formula

ICD-O –Codes can be specified by the following qualifier:

Here ICD-O provides additionally the following codes for Lymphoma, which specify the Cell line: B-Cell, T-Cell, Null-Cell Lymphoma. ICD-O uses the Codes 1 – 9. A detailled System is discribed in Chapter 9 under 9.5.2 and 9.53.

Example

GRAPHIC IS MISSING

DisplayName is only available in correlation to qualifiers. According to ICD-O-3 formation rule there are much more discriptions possible as ICD-Catalog proposes.

TNM Classification

The TNM classification describes the expansion (spread) of the tumor , i.e. stadium and prognosis of the disease.

As a special feature, the TNM classification uses the same notation for all tumors but supports different interpretations for different entities.

As an example, a T3 for mamma carcinoma has a different interpretation then the stomach carcinoma.

The current edition is 7th which is valid since January 2010, which is a reason why many TNM-6- codes may still be in use. Therefore all TNM-codes should have a version identifier, because non translatable differences are in the different editions.

A simple overview can be found in http://de.wikipedia.org/wiki/TNM.

The T category will be used for the expansion of the primary tumor, where the stages T0, Tis, T1-T4 und TX are being used, the "higher" the number, the more progress is being diagnosed and the more adverse the prognosis.

T0 stands for "no primary tumor found" (e.g. because being eradicated by therapy) Tis stands for a very early (non-infiltrating) stage tumor (Tumor in situ) and TX stands for a diagnosis which can not judge the stage because of missing data

For some tumors subcategories like e.g. T2a, T2b have been defined.

The N-category classifies the affection of lymphatic nodes - usingN0, N1-N3, NX, where N0 means "no lymphatic node affected".

For some tumors, thisexclusion ("N0") requires the examination of a minimum amount of nodes.

The higher the N category the more severe is the lymphatic node affection.

If no sufficient data is available NX is being diagnosed.

The M category describes the existence of distant metastases, with the vallues of M0 (no metastases detectable), M1 (metastases detectable) and MX (insufficient data).

The TNM can be used according to clinical criteria (preoperative, cTNM) and according to the pathology findings (pTNM).

For many patients one single diagnoss will be made, either a cTNM or a pTNM, such that this type of finding must be distinguished.

This preoperative ("c" or no prefix) / pathology ("p") attribute can be captured independently for each of the T N M categories.

Therefore the typically used pTNM often meanes pTpNcM, because the spread of a timur can best be diagnosed through surgery while lymphatic spread only by pathology.

The prefix "r" describes remaining tumors (after non-disease intervals) and a prefix "y" if the classification was assessed after systemic or radiation treatment (ycTNM, ypTNM etc.).

For multiple Primary tumors the suffix "m" (or the number of tumors) will be put after the T-category value(T2(m), T2(5)).

Therefore a complete TNM formula looks like this:

There are voluntary components e.g. the certainty-Faktor (C-Factor)

Other components require pathology lab examination (L-, V- or Pn-Category)

• y-Symbol (y or empty, disgnosis after systematic or xray treatment)
• r-Symbol (r or empty, remainder)
• p/c/a-Symbol for pT-category (clinical or pathological)
• T-Category
• (m) for multiple localizations or number of tumors
• C-Factor for T-Category (certainty)

• L-Category
• V-Category
• Pn-Category
• p/c/a-Symbol for pN-Category (clinical or pathological)
• N-Category
• C-Factor for N-Category (certainty)

• p/c/a-Symbol für pM-Category
• M-Category
• C-Factor for M-Category (certainty)
• S-Kategorie (serological values, only for testicle tumors)
• UICC-Stadium (Grading via UICC 0 and I-IV together with

letter A, B and C for further classification).

For some tumors further modifiers are being documented as a suffix (mostly in parenthenses) like e.g. (sn), (mol-),(mol+).

In addition, the TNM supplement introduces innovative or "under test" extensions, which raises doubts whether ta full control of TNM entries.

Typical T-Categories (without pre-/suffices) are being listed in chapter "Sites"

Typical N-Categories (without pre-/suffices) are being listed in chapter "Nodes".

Typical M-Categories (without pre-/suffices) are being listed in chapter "Metastases".

Qualifiers of the Tumor Formula

Despite values for T,N and M the TNM formula may also contain various qualifiers. The following table gives an overview which qualifiers can be used for which information and where they are being used. This is case-sensitive!

a Autoptical c Clinical C C-Faktor (certainty) G histopathological Grading L Lymphatic vessel invasion m multiple Tumors M distant metastases N Regional lymphatic node metastases p pathological Pn perineural Invasion r Rezidiv tumor R Residual tumor after treatment sn Sentinel-Lymphatic nodes Stage Anatomic Stage-Grouping T Expansion (spreading) of Primary tumor V Venous invasion y Classifikation after initial multi-modal Therapy

Ann Arbor Classification

For lymphoma the TNM-classification does not make sense and therefore theso-called Ann-Arbor classification will be applied.

In this system, the stages I-IV are being distinguished, with an additional suffix letter - A meaning "no general symptoms" - B "with general symptoms" - E "extra-lymphatic organ affected" - S "spleen affected"

As with TNM, the Ann-Arbor classification distinguishes between cliniclal (cS) and pathological (pS) grading.

According to Durie & Salmon tere are gradings from I to III or the grades according to SWOG from 1-4 for the "Multiple Myeloma".

FIGO Stages

FIGO stages ignificantly overlap with the TNM classification, especially on the T-axis.

Therefore no details are being given here.

Gleason Score

The so-called Gleason-Score serves to classify the prostate carcinoma. The total numeric value is the sum of two indicators for • loss of differentiation (1-5) • growth pattern (1-5)

Resulting values range from 2 to 10 (also see Scores & Assessment DSTU).

Furthermore there is a more recent Gleason classification (according to Dhom, Müller and Helpap [Helpap 2002, Helpap2007]), which also requires to specify the procedure (esp. the two degrees) being used.

Papanikolaou

The so-called Pap-Test [Pap] is based on colored cell samples from the cervix and is used as an early indocator for cervical cancers.

WHO Grading

The so-called WHO Grading serves as an individual progonossi on the one hand and also is an indicator towards further treatment on the other hand.

Tumors of WHO Grade I and II in most cases can be treated by surgery alone, while tumors with WHO Grading III and IV normally need additional treatment by radiation or chemotherapie after surgery.

The grading looks like this:

Code	Codename	Meaning
I		benign,slow growth of tumor, very good prognosis
II		still benign, slow growth of tumor,tendency to recur
III		malignant,actively producing abnormal cells,tends to recur
IV		very malignant,fast growth,needs systemic therapy, bad prognosis

Table 9: WHO Grading (OID 1.2.276.0.76.5.394)

The fourth edition of the "World Health Organization (WHO) Classification of tumours of the central nervous system" (2007) lists all relevant tumor entities.

Codes for Gleason Score

The Gleason Grading system helps evaluating the prognosis of men with prostate cancer, as a part of a strategy of prostate cancer staging which predicts prognosis and guides therapy. The Gleason score is based on microscopic findings.

Code	Description	German
1	Round to oval equal individual glands, lying close to each other, sharply demarcated from the surrounding area	Runde bis ovale gleich große Einzeldrüsen, dicht nebeneinander liegend, scharf gegen die Umgebung abgegrenzt
2	Slightly less uniform single glands, separated by small amounts of stroma, less sharply defined tumor margin	Etwas weniger uniforme Einzeldrüsen, getrennt durch geringe Mengen von Stroma, weniger scharf begrenzter Tumorrand
3	a) Irregularly large and irregularly shaped glands, usually with abundant stroma, sometimes also stored tightly irregular and indistinct tumor border	Unregelmäßig große und unregelmäßig gestaltete Drüsen mit gewöhnlich reichlicherem Stroma, gelegentlich auch dicht gelagert, unregelmäßige und unscharfe Tumorgrenze
	b) Papillary or cribriform structures, sometimes in large gang­like formations	Papilläre oder kribriforme Strukturen, z.T. in großen gangähnlichen Bildungen
4	"a) Large irregular Epithelformationen by glandular fusion (""fused glands"") and branched glands with irregular infiltration into the surrounding area "	Große unregelmäßige Epithelformationen durch Drüsenverschmelzung („fused glands“) sowie verzweigte Drüsen mit unregelmäßiger Infiltration in die Umgebung
	b) Adenocarcinoma with prominent clear cytoplasm similar to clear cell adenocarcinomas of the kidney	Adenokarzinom mit ausgeprägt klarem Zytoplasma ähnlich hellzelligen Adenokarzinomen der Niere
5	a) Circumscribed round epithelial clusters with mostly solid and cribriform construction, usually with central necrosis	Scharf begrenzte runde Epithelhaufen mit meist solidem und kribriformem Bau, gewöhnlich mit zentraler Nekrose
	(comedo carcinoma­like)	(komedo­karzinomähnlich)
	b) Irregularly shaped formations of an undifferentiated carcinoma, which only just discernible glandular formation or is identified vacuoles (signet ring­like) than adenocarcinoma	Unregelmäßig begrenzte Formationen eines undifferenzierten Karzinoms, das nur durch gerade noch erkennbare Drüsenbildung oder Vakuolen (siegelringähnlich) als Adenokarzinom zu identifizieren ist

Table 31: Loss of Differentiation according to Gleason Score ref. 19 (OID 1.2.276.0.76.5.402)

Documentation by the GleasonSum (Gleason¬Score) as the sum of the two most dominating findings: Uniformly structured tumors: two times the points of above table. Non-uniformly structured tumors: points for the dominating share of findings (so-called primary grading) + points for second-largest share (secondary grading), if punch biopsy show more than two grades, the second component will be based on the most adverse component found.

Ann Arbor Codes

The tumor staging system for lymphomas.

Principal Stages

Code	Description
I	cancer is located in a single region, usually one lymph node and the surrounding area
II	cancer is located in two separate regions, an affected lymph node or organ and a second affected area, and that both affected areas are confined to one side of the diaphragm
III	cancer has spread to both sides of the diaphragm, including one organ or area near the lymph nodes or the spleen
IV	diffuse or disseminated involvement of one or more extralymphatic organs

Table 33: Ann Arbor (OID 1.2.276.0.76.5.405)

Modifiers for Constitutional Symptoms

Code	Description
A	absence of constitutional symptoms is denoted by adding an ""A""
B	presence of constitutional (B-type) symptoms is denoted by adding a ""B""

Table 34: Ann Arbor constitutional symptoms (OID 1.2.276.0.76.5.416)

Modifiers for Spread of Tumor

Code	Description
E	disease is ""extranodal"" (not in the lymph nodes) or has spread from lymph nodes to adjacent tissue.
S	the disease has spread to the spleen.
X	the largest deposit is >10 cm large (""bulky disease""), or the mediastinum is wider than 1/3 of the chest on a chest X-ray.

Papanicolaou Coding

Results of the so-called Pap-Test

Code	Meaning
Pap0	non representative sample
PapI	normal cell findings
PapII	atypical, benign disorder, infection, metaplasia, atrrophy, bacteria, viruses,
PapIIw	insufficient samples
PapIII	cell proliferation and atypic cells
PapIIID	dysplastic , mostly with HPV infection
PapIIIG	moderate/severe dyskaryosis and/or dysplasia
PapIV	biopsy sample and histological clarification required
PapIVa	carcinoma in situ
PapIVb	single certain tumour cells, carcinoma very certain
PapV	many certain tumour cells, carcinoma certain, cellular changes suggestive of invasive squamous carcinoma, and cellular changes indicative of adenocarcinoma of the uterine cervix and other invasive cancer.
