0.1 Canadian Cancer Registry overview

The patient–oriented Canadian Cancer Registry (CCR) evolved from the event–oriented National Cancer Incidence Reporting System (NCIRS). Beginning with cases diagnosed in 1992, incidence figures collected by Provincial and Territorial Cancer Registries (PTCRs) have been reported to the CCR, which is maintained by Statistics Canada. Established as a person–oriented database, the CCR includes mechanisms for updating and clearing death records and is linked to provincial and territorial databases to help track patients across Canada who have been diagnosed with tumours.

0.2 CCR system guide document organization

The CCR System Guide has been separated into three parts to improve access and navigation. Although the three parts are separate, the three documents should be used in conjunction with each other. The different sections of the three–part CCR System Guide often refer to each other. The CCR System Guide is now composed of:

Part I: CCR Data Dictionary provides explanation on the reporting of data, including the scope and detailed information on the input and derived variables.

Part II: CCR Data Loading and Tabulation Master Files provides information on the data loading process, including in–depth descriptions of the various edits performed on the data. Part II also provides information on the Tabulation Master Files, including the scope, content and layout. Part II is followed by several appendices that contain supporting information such as explicit code set tables, guidelines to assist coders and other supportive information.

Part III: CCR Core Reference Tables provides detailed information on the CCR Core Reference Tables such as descriptions of the tables, their usage and any revisions made. Part III is an accompanying document to the "CCR Reference Tables 2009.xls".

0.3 Part I document organization: CCR Data Dictionary

Chapter 1 – Reporting data describes what data that should be reported and how it should be reported to CCR. It also gives some examples of the most common operations for reporting data to CCR.

Chapter 2 – Data dictionary describes all data managed by the system including system–derived variables. For every datum, it also includes a list of related edits that describes the constraints on the datum and the relationship it has with other data.

Notes:

• Tumours with ICD–O–3 Behaviour Codes '6' and '9' must not be reported to the CCR.
• For cases diagnosed in 2007 and onwards, duplicate tumours based on the SEER multiple primary/histology rules must not be reported to CCR.
• For cases diagnosed prior to 2007, duplicate tumours based on the CCR multiple primary rules must not be reported to the CCR. See Appendix D (Part II – CCR Sytem Guide) – multiple primary tumours rules for CCR for more detail.
• Tumours occurring in patients residing outside of Canada must not be reported to CCR. See Appendix T (Part II – CCR Sytem Guide) – Residency guidelines in Canada for more detail.

1.1.2.2 CCR collaborative staging scopeAll tumours within the CCR core scope and diagnosed in 2004 and onwards should be staged according to the Collaborative Staging Manual and Coding Instructions version 01.04.01 (March 25, 2008) available from the Collaborative Staging Task Force of the American Joint Committee on Cancer.

See next section for more details on how to report collaborative staging data.

1.1.2.3 CCR AJCC TNM staging scope

Colorectal, breast and prostate primary tumours diagnosed in 2003 and onwards can be staged according to their corresponding AJCC TNM 6^th Edition staging schema. Reportable tumours are selected based on International Classification of Diseases for Oncology – 3^rd Edition (ICD–O–3) as shown in the following table.

Table 3 CCR AJCC TNM staging scope

Date of diagnosis	Site	ICD–O–3 Topography codes	ICD–O–3 Histology codes	ICD–O–3 Behaviour codes
2003/01/01 and onwards	Colorectal	C18.0 to C18.9; C19.9; C20.9	8000 to 8576; 8935 to 8936; 8940 to 8950; 8980 to 8981	2, 3

See next section for details on how to report AJCC TNM staging data.

1.2 How data should be reported

1.2.1 Input record files

Data must be reported to the Canadian Cancer Registry (CCR) system using flat files encoded with an ISO 8859–1 (Latin 1) compatible character set. Patient data must be reported using the input patient record file and the tumour data must reported using the input tumour record file. See corresponding input record layouts in Table 4 and Table 5 below.

In addition to the specific data items, every input record has a record type and a date of transmission. The record type indicates which action should be conducted by the CCR system (adding, updating or deleting a record in the CCR) while the date of transmission is needed for tracking purposes. For details on a given data item, see its corresponding section in Chapter 2.

Although a data submission (also called a cycle) is normally composed of two files (one input patient record file and one input tumour record file), it may also be composed of only one file for specific needs (for example, updating tumour information only).

1.2.2 CCR fundamentals

Following is a list of fundamental rules and concepts that may help the Cancer Registries understand the constraints related to data submission to the CCR.

Submission

• Input record files must indicate coherent operations for related patient and tumour records.
• A PTCR can only report data for its jurisdiction.

Ownership

• A Patient record is initially owned by its reporting province/territory. Its ownership may change through the internal record linkage process; if it is found that the same patient is owned by two provinces/territories, sole ownership of the Patient record will be assigned to the province/territory which reported the latest tumour record.
• A Tumour record is always owned by its reporting province/territory. The ownership of a tumour record never changes.
• A PTCR must own a patient or tumour record in order to update or delete it.

Integrity

• Every patient record must be associated with at least one tumour record from the same province/territory.
• Every tumour record must be associated with one patient record.
• The CCR contains only valid and coherent patient and tumour records. Consequently, invalid or incoherent records are rejected by the data editing process. As a temporary measure, invalid staging data (Collaborative Staging and/or AJCC TNM Staging) will not prevent valid core tumour fields from being loaded in the CCR database. In this case, invalid staging data will not be loaded but will be marked as being rejected in the CCR database.

Keys

• The Patient identification number (PIN) must be unique for each patient record from a given province/territory.
• Tumour reference number (TTRN) must be unique for a patient's tumour record from a given province/territory.
• CCR identification number (CCR_ID) connects patient record to its related tumour records from any province/territory.

Scope

• Tumours outside the CCR core scope are not loaded.
• For a given patient record, duplicate tumours based on the CCR multiple primary tumour rules are not loaded.
• Collaborative staging data for tumours outside the CCR collaborative staging scope are not loaded.
• AJCC TNM staging data for tumours outside the CCR AJCC TNM staging scope are not loaded.

1.2.3 Reporting collaborative staging data

1.2.3.1 Typical cases

Case 1: Tumours outside the CCR collaborative staging scope (see section 1.1.2.2)

All corresponding variables (T27 to T41 and T52) must be left blank.

Case 2: Tumours within the CCR collaborative staging scope (see section 1.1.2.2)

• If the tumour has been staged using the collaborative staging schema, then all corresponding variables (T27 to T41 and T52) must be reported according to the recommended version of the Collaborative Staging Manual and Coding Instructions (see section 1.1.2.2) available from the Collaborative Staging Task Force of the American Joint Committee on Cancer. Unknown variables must be coded using the proper CS schema specific 'Unknown' code.

• If the tumour has not been staged using the collaborative staging schema, then all corresponding variables (T27 to T41 and T52) must be coded using the proper CCR Specific 'Not Staged' code. Variables must not be left blank.

Table 6 CCR Specific 'Not Staged' codes

T27	T28	T29	T30	T31	T32	T33	T34	T35	T36	T37	T38	T39	T40	T41	T52
999	99	9	99	9	99	99	99	9	999	999	999	999	999	999	999999

1.2.4 Reporting AJCC TNM staging data

1.2.4.1 TNM staging overview

The AJCC TNM system is based on the assessment of the T, N, and M components and the assignment of a stage grouping. The structure of TNM varies from site to site. Recurrent tumours (prefix 'r') are not to be staged or submitted to the CCR.

T component

The T element designates the extent of the primary tumour (size or depth of invasion). The numerical subset increases with the progressive extent of the malignant disease. For example:

• Small lesion confined to the organ of origin would be coded as T1;
• Larger tumour size or deeper extension into adjacent structures, tissues, capsules, or ligaments as T2;
• Larger tumour size or extension beyond the organ of origin but confined to the region, T3;
• Massive lesion or one that directly invades another organ or viscera, major nerves, arteries, or bone as T4.

N component

The N component designates the presence or absence and extent of metastasis in the regional lymph nodes.

• In some sites, there is an increasing numerical value based on size, fixation, or capsular invasion.
• In other sites, the numerical value is based on multiple nodal involvement or number and location of the regional lymph nodes.

M component

The M component identifies the presence or absence of distant metastases, including lymph nodes that are not regional.

Stage group

The stage group is assigned using the table listed in the corresponding chapter of the AJCC Cancer staging manual. Stage 0 reflects minimal involvement, usually carcinoma in–situ, whereas Stage IV indicates either greatest tumour involvement or distant metastasis. Histologic grade and age may impact staging in certain sites.

1.2.4.2 Typical cases

Case 1: Tumours outside the CCR AJCC TNM staging scope (see section 1.1.2.3).

All corresponding variables (T42 to T51) must be left blank.

Case 2: Tumours within the CCR AJCC TNM staging scope (see section 1.1.2.3).

• If the tumour has been staged using the AJCC TNM system then all corresponding variables (T42 to T51) must be reported according to the CCR data dictionary corresponding sections. Variables must not be left blank. Unknown variables must be coded using the proper 'Unknown' code.
• If the tumour has not been staged using the AJCC TNM staging system, then all corresponding variables (T42 to T51) must be coded using the proper CCR Specific 'Unknown'/'Not Staged' code (see table below). Variables must not be left blank.

Table 7 CCR Specific 'Unknown' or 'Not Staged' codes

T42	T43	T44	T45	T46	T47	T48	T49	T50	T51
99	99	99	99	99	99	99	99	99	00

1.2.4.3 Data quality

Stage group is "required" for all histology codes listed at the end of the applicable AJCC chapters, including the published (posted) AJCC errata. Cases meeting those requirements must have a clinical stage group (T47) and/or a pathological stage group (T48) and/or TNM stage group (T50) with a valid stage group as defined in the appropriate chapter of the AJCC Cancer staging manual, sixth edition. Unknown stage group will not prevent AJCC TNM staging data from being loaded in the CCR but will be reported through data quality reports.

The following table depicts which ICD–O–3 topography and histology codes require a stage group. All sites included in the following table are also included in the CCR AJCC TNM staging scope.

Tumours within the CCR AJCC TNM staging scope but not listed in the above table may have unknown stage groups. These cases will not be reported through data quality reports.

1.2.4.4 Technical notes

Extra descriptors
As described on pages 7 and 8 of the AJCC Cancer staging manual, sixth edition, 2 prefixes and 1 suffix are used to identify special cases of TNM or TNM classifications.

Table 9 Descriptors used in AJCC Cancer staging manual, sixth edition

Prefixes		Suffixe
y	Staging is performed during or after treatment (ycTNM or ypTNM)	m	Multiple primary tumours in a single site: pT(m)NM
a	Stage determined at autopsy

These prefixes and suffixes do not affect the stage grouping but they identify pieces of information that require these cases to be analyzed separately. The staging implementation working group decided that the additional descriptors would not be collected in the CCR, as they could not be collected consistently across the country. Therefore, if a registry collects descriptors for an eligible staging record, corresponding variables must be reported without them.

Assigning X

Values	Meaning	Example
TX	Primary Tumour cannot be assessed	When the tumour is identified, but there is not enough information from clinical observation, imaging or microscopic depth of invasion, size, etc. to assign a value. This could also mean that the patient did not return for further workup or treatment.
NX	Regional Lymph nodes have not been or cannot be evaluated	When initial resection takes place, but further workup or treatment is refused, the status of the regional lymph nodes is not available.
MX	Distant metastasis cannot be assessed	When studies have not been performed to adequately assess the presence of metastases.
Clinical or Pathological stage group X	May mean that the case cannot be stage grouped	When there is at least one T, N or M component listed as 'X' but T, N, M components combination does not lead to a stage group.

Prostate cases

If initial diagnosis is through biopsy, and then the patient is put on "watchful waiting" for a period of time, followed by a prostatectomy, then the date of diagnosis should be the date of the biopsy. If the intent of waiting is considered treatment, then the case can only be clinically staged, based on the biopsy information. This initial information can be used for clinical staging information, but there would not be a pathological stage available. This would then be listed with pathologic TNM values of 'X', since the information is not available.

If the intent of the waiting is for surgery, then the information from the prostatectomy can be used for pathologic staging, according to page 5 of the AJCC Cancer staging manual, sixth edition.

T12 – Date of diagnosis

Acronym: TDATDIAG

Description: The date of diagnosis of the tumour. It is determined using the following sequence order (effective since 2004 for all data):

1. Date of cytological diagnosis
   
   If suspicious cytology is confirmed by subsequent histological diagnosis (including autopsy) or clinical impression of cancer supports the cytology findings, then the cytological diagnosis date will be used.
    
2. Date of histological diagnosis, including cases diagnosed only on autopsy
    
3. Date of non microscopically confirmed diagnosis. including:
    

   a)Positive laboratory test/marker study;
   b)Direct visualization without microscopic confirmation (surgery without histology);
   c)Radiography and other imaging techniques without microscopic confirmation;
   d)Clinical diagnosis, including: physical findings (without histology); 
   e)Method of Diagnosis unknown.

4. Date of death, if not reported at any other time.Includes:
    

   a) Death certificate only;
   b) Autopsy only.

Exceptions
1. If applicable, the date associated with the method that prompts treatment takes precedence over the above choices and should be chosen.
2. If autopsy only case, follow back as per the Guidelines for abstracting and determining DCO cases for PTCRs in Canada (see Appendix I (Part II – CCR System Guide)). If previous information is available for this tumour, the initial date takes precedence, including if it is non microscopic information. For example, if an x-ray result is available prior to the autopsy; the date associated with this initial diagnostic information takes precedence over the autopsy (histological) date.

Refer to the CCR guidelines for ambiguous terms (See Appendix H (Part II – CCR System Guide)) when determining the date of diagnosis.

Date of diagnosis is linked to the Input tumour variable T24 - Method used to establish the date of diagnosis.

Specific values & meaning (T24)

Value	Meaning
0	For Date of diagnosis prior to 2004 Not reported. (Refer to T11 – Method of diagnosis.)
1-3	Microscopically confirmed
1	Positive cytology Cytological diagnoses based on microscopic examination of cells as contrasted with tissues. Included are smears from sputum, bronchial brushings, bronchial washings, tracheal washings, prostatic secretions, breast secretions, gastric fluid, spinal fluid, peritoneal fluid, and urinary sediment. Cervical and vaginal smears are common examples. Also included are diagnoses based upon paraffin block specimens from concentrated spinal, pleural and peritoneal fluid. Fine needle aspiration is included here.
2	Positive histology Histological diagnoses based upon tissue specimens from biopsy (including wide core and needle biopsy), frozen section, surgery, autopsy or D and C. Positive hematological findings relative to leukemia, including peripheral blood smears, are also included. Bone marrow specimens (including aspiration biopsies) are coded as '2'.
3	Autopsy only Diagnosis confirmed by autopsy only, (if tissue taken) when no other information available.
4-9	Non-microscopically confirmed
4	Positive laboratory test/marker study Clinical diagnoses of cancer based on certain laboratory tests or marker studies, which are clinically diagnostic for cancer. This includes alpha-fetoprotein for liver cancer and abnormal electrophoretic spike for multiple myeloma. Elevated PSA is non-diagnostic for cancer. If the physician uses the PSA as a basis for diagnosing prostate cancer with no other work-up, it should be recorded as code 4.
5	Direct visualization without microscopic confirmation (surgery without histology) Visualization includes diagnosis made at surgical exploration, including autopsy where no tissue is taken, or by use of the various endoscopes (including colposcope, mediastinoscope, and peritoneoscope). However, use only if such visualization is not supplemented by positive histology or positive cytology reports.
6	Radiography and other imaging techniques without microscopic confirmation Cases with diagnostic radiology for which there is neither a positive histology nor a positive cytology report. 'Other imaging techniques' include procedures such as ultrasound, computerized (axial) tomography (CT or CAT) scans, and magnetic resonance imaging (MRI).
7	Clinical diagnosis, including physical findings (without histology) Cases diagnosed by clinical methods not mentioned above and for which there were no positive microscopic findings.
8	Death certificate only Cases diagnosed by Death certificates only, when no other information available.
9	Method used to establish the date of diagnosis unknown.

T53– Ambiguous terminology diagnosis

Acronym: TAMBIGTERM

Description: Identifies all cases, including death certificate only and autopsy only, for which an ambiguous term is used to establish a cancer diagnosis (for example, to determine whether or not the case is reportable). Ambiguous terminology may originate from any source document, such as pathology report, radiology report, or from a clinical report. This data item is used only when ambiguous terminology is used to establish diagnosis. It is not used when ambiguous terminology is used to clarify a primary site, specific histology, histologic group, or stage of disease. It is not used if there is any conclusive statement of a cancer diagnosis in the medical record.

This data item will identify specific primary sites where the ambiguous terminology is commonly used to describe or establish a cancer diagnosis.

Refer to the SEER Multiple Primary and Histology Coding Rules Manual (page 335-337) for more details on definitions, time frames, coding instructions and examples.

Refer to the CCR Appendix I (Part II – CCR System Guide): Guidelines for Ambiguous Terms, as referenced in T12 (date of diagnosis).

2.4 Derived tumour variables

The derived tumour variables are variables related to the tumour and copied/derived/calculated by the CCR system through various processes such as data loading, record linkage and death clearance. Table 13 lists all the derived tumour variables; the following pages describe these variables in more detail.

For convenience, variables are presented in order by variable number. The reader can easily find the page corresponding to any variable by looking for the variable number in the title. For example, age at diagnosis is described on page TD3 – Age at diagnosis.
