SEQUENCE NUMBER--CENTRAL

NAACCR Item #: 380
SEER*Stat Name: Sequence number
PEDSF SAS Variable Name: seq1-seq10
Item Length: 2

Field Description:	Sequence Number-Central describes the number and sequence of all reportable malignant, in situ, benign, and borderline primary tumors, which occur over the lifetime of a patient.  The sequence number may change over the lifetime of the patient.  If an individual previously diagnosed with a single reportable malignant neoplasm is subsequently diagnosed with a second reportable malignant neoplasm, the sequence code for the first neoplasm changes from 00 to 01.

This sequence number counts all tumors that were reportable in the year they were diagnosed even if the tumors occurred before the registry existed, or before the registry participated in the SEER Program.  The purpose of sequencing based on the patient’s lifetime is to truly identify the patients for survival analysis who only had one malignant primary in their lifetimes.

(Continued on next page)
(Continued from SEQUENCE NUMBER-CENTRAL)

Codes
In Situ/Malignant as Federally Required based on Diagnosis Year
00	One primary only in the patient’s lifetime	
01	First of two or more primaries	
02	Second of two or more primaries	
..	(Actual number of this primary)	
41	Forty-first of forty-one or more primaries	
99	Unspecified or unknown sequence number of Federally required in situ or malignant tumors.  Sequence number 99 can be used if there is a malignant tumor and its sequence number is unknown.  (If there is known to be more than one malignant tumor, then the tumors must be sequenced.)	

Non-malignant Tumor as Federally Required based on Diagnosis Year
60	Only one non-malignant tumor or central registry-defined neoplasm	
61	First of two or more non-malignant tumors or central registry-defined neoplasms	
62	Second of two or more non-malignant tumors or central registry-defined neoplasms	
..	..	
87	Twenty-seventh of twenty-seven	
88	Unspecified or unknown sequence number of non-malignant tumor or central-registry defined neoplasms.  (Sequence number 88 can be used if there is a non-malignant tumor and its sequence number is unknown. If there is known to be more than one non-malignant tumor, then the tumors must be sequenced.)	

MONTH OF DIAGNOSIS

HISTOLOGY (92-00) ICD-O-2

NAACCR Item #: 420 
SEER*Stat Name: Histology (92-00) ICD-O-2
PEDSF SAS Variable Name: hist2_1-hist2_10
Item Length: 4

Field Description:	NOTE:  ALL CASES DIAGNOSED 1973-91 HAVE BEEN CONVERTED TO THE INTERNATIONAL CLASSIFICATION OF DISEASES FOR ONCOLOGY, SECOND EDITION (ICD-O-2, 1992).

The SEER program has used several different, but related, coding systems for morphology over time.  One should be extremely careful when doing any analysis of trends related to morphology.  It is suggested that these analyses start with diagnoses no earlier than 1977 and that special attention be paid to the changes for 1986-91 cases due to the use of the International Classification of Disease for Oncology, Field Trial Edition, March 1988 and for 1992+ cases due to the use of ICD-O-2.   

Analyses of morphology data are usually limited to microscopically confirmed cases only.

HISTOLOGY CODING

FOR CASES DIAGNOSED 1973-85:

Histologic types are defined in the morphology section of the International Classification of Diseases for Oncology, 1976 Edition (ICD-O, 1976).  However prior to the introduction of ICD-O, 1976, morphology was coded using the Manual of Tumor Nomenclature and Coding, 1968 (MOTNAC).  With the introduction of ICD-O, 1976, all cases previously coded using MOTNAC were machine converted without hand review using the conversion table, Conversion of Morphology Sections (neoplasms) of 1968 Manual of Tumor Nomenclature and Coding (MOTNAC) and 1965 Systematized Nomenclature of Pathology (SNOP) to 1976 International Classification of Diseases for Oncology, developed by Constance Percy.  The morphology codes of ICD-O, 1976, are more specific than those of MOTNAC.  Thus, less detailed information on morphology is available for cases diagnosed 1973-76.  For example, when using MOTNAC large cell carcinoma is included with carcinoma, not otherwise specified (NOS); when using ICD-O, 1976, large cell carcinoma is a separate entity having its own code.  All have been machine converted to ICD-O-2.

FOR CASES DIAGNOSED 1973-85:

In addition, the following special morphology codes were used by the SEER Program:

Breast — All years

8522/3	Infiltrating duct carcinoma and lobular carcinoma	
8523/3	Infiltrating duct carcinoma and lobular carcinoma in situ	
8524/3	Intraductal carcinoma and lobular carcinoma	
8522/2	Intraductal carcinoma and lobular carcinoma in situ	
8543/3	Paget’s disease with intraductal carcinoma	

All sites — Introduced for coding in approximately 1982

9616/3	Lennert’s lymphoma	
9624/3	Malignant lymphoma, large cell, cleaved, diffuse	
9634/3	Malignant lymphoma, large cell, non-cleaved, diffuse	
9723/3	True histiocytic lymphoma	

(Continued on next page)

(Continued from HISTOLOGY (92-00) ICD-O-2)
FOR CASES DIAGNOSED 1986-91:

Histologic types are defined in the morphology section of the International Classification of Diseases for Oncology, Field Trial Edition, 1986 (ICD-O FT).  (This volume is no longer available. It was replaced by the International Classification of Diseases for Oncology, Field Trial Edition, March 1988 (ICD-O FT 1988).  Pages i-vi, 23 of the latter volume list the differences between the two Field Trials, present a summary of the changes to ICD-O, 1976, and define the symbols used in the morphology section.  These were converted to ICD-O-2.

FOR CASES DIAGNOSED 1992-2000:

Histologic types are defined in the morphology section of ICD-O-2.  See pages 137+ in ICD-O-2 for additions and changes.

FOR CASES DIAGNOSED AFTER 2000:

All cases diagnosed after 2000 were converted from ICD-O-3 to ICD-O-2.

Field Description: 	The actual coding schemes for individual sites and time periods can be viewed at http://seer.cancer.gov/manuals/historic/AppendD.pdf.  The discussion below summarizes the information available by site and time period.

This field specifies information on surgery during first course of therapy whether it was cancer-directed or not.  (Prior to 1988 SEER did not collect information on surgical procedures if not cancer-directed.)  The Reason for No Cancer-directed Surgery field must be used to distinguish among no cancer-directed surgery performed; cancer-directed surgery recommended, unknown if performed; and unknown if cancer-directed surgery performed.

FOR CASES DIAGNOSED 1973-82:
All cases were coded using the following nonspecific scheme:

No Cancer-Directed Surgery/Unknown1

00	No surgical procedure	
09	Unknown if surgery done	

(Continued on next page)

(Continued from RX SUMM-SURG TYPE)

Type of Cancer-Directed Surgery

90	Surgery, NOS	

1Code '09' must be used in conjunction with Reason for No Cancer-directed Surgery to distinguish "No cancer directed surgery" from "Unknown if cancer-directed surgery performed" and "Cancer-directed surgery recommended but unknown if given."  Code ‘00’ is only used for cases diagnosed only at autopsy.

FOR CASES DIAGNOSED 1983-87:
Detailed schemes were in place for the following sites:

SEER HISTORIC STAGE A

NAACCR Item #: N/A
SEER*Stat Name: SEER historic stage A
PEDSF SAS Variable Name: hstst1-hstst10
Item Length: 1

Field Description:	Derived from Collaborative Stage (CS) for 2004+ and Extent of Disease (EOD) from 1973-2003.  It is a simplified version of stage: in situ, localized, regional, distant, & unknown.  Over time several different EOD schemes have been used.  Thus caution should be used when doing trend analysis.  

For more information including sites and years for which it isn't calculated, see http://seer.cancer.gov/seerstat/variables/seer/lrd-stage.

Codes

0	In situ — A noninvasive neoplasm; a tumor which has not penetrated the basement membrane nor extended beyond the epithelial tissue.  Some synonyms are intraepithelial (confined to epithelial tissue), noninvasive and noninfiltrating.	
1	Localized — An invasive neoplasm confined entirely to the organ of origin.  It may include intraluminal extension where specified.  For example for colon, intraluminal extension limited to immediately contiguous segments of the large bowel is localized, if no lymph nodes are involved.  Localized may exclude invasion of the serosa because of the poor survival of the patient once the serosa is invaded.	
2	Regional — A neoplasm that has extended 1) beyond the limits of the organ of origin directly into surrounding organs or tissues; 2) into regional lymph nodes by way of the lymphatic system; or 3) by a combination of extension and regional lymph nodes.	
4	Distant — A neoplasm that has spread to parts of the body remote from the primary tumor either by direct extension or by discontinuous metastasis (e.g., implantation or seeding) to distant organs, issues, or via the lymphatic system to distant lymph nodes.	
8	Localized/Regional – Only used for Prostate cases.	
9	Unstaged — Information is not sufficient to assign a stage.
