This is a one digit code which summarizes the stage of disease at time of initial diagnosis and/or first treatment. It only applies to cancers diagnosed on or after January 1, 2001. It will be calculated based on information coded in the SEER Extent of Disease fields for cases diagnosed from 1-1-2001 to 12-31-2003. For cases diagnosed on or after 1-1-2004, it will be calculated from the Collaborative Stage data items. This will no longer be used for cases beginning January 1, 2018 you will use Summary Stage 2018.

Refer to the Summary Staging Guide of the SEER Program to determine the general stage. Briefly described, they are:

Code

Description

Code

Description

0

In-situ/non-invasive malignant tumor. The pathology report must state "in-situ". In addition there must be no evidence of invasion mentioned anywhere in the record in order for a tumor to be staged in this category. (The following synonyms may also be used instead of "in-situ": intraepithelial, intraepidermal, non-infiltrating, intraductal, or  Bowen's Disease.)

1

Localized - tumor is confined to the organ of origin.

2

Regional by direct extension - tumor has spread by direct extension to immediately adjacent tissues or organs.

3

Regional to lymph nodes - tumor has spread into lymph nodes regional to the primary site of origin.

4

Regional by both direct extension and regional lymph nodes.

5

Regional, NOS - tumor is regionally spread, but the extent of regional spread cannot be determined, or is not specified.

7

Distant metastasis - a tumor that has spread beyond the immediately adjacent tissues and has developed secondary or metastatic tumors, has seeding or implants, or is systemic. Leukemia, multiple myeloma, reticuloendotheliosis, hematopoietic diseases, and Letterer-Siwe's disease are always coded 7.

8

Not applicable - For non malignant (benign or borderline) tumors of the CNS----This code is never used to stage malignant tumors.

9

Unknown/Unstageable - Use when there is not enough information available to accurately determine the stage. Every effort should be made to determine the stage by thoroughly reviewing the record or obtaining information from a medical authority before using code 9.

Code '9' should be used for unknown primaries, because staging for these cases is not applicable.

In the case of patients first treated elsewhere and admitted to your hospital for a subsequent course of treatment, enter the stage at the time of initial diagnosis, if it is known. If not, record the stage as "Unknown". Do not record the stage at the time of admission to your hospital for subsequent treatment.
