SEER Errata for ICD-O-3 Site/Type Validation List. April 1, 2009

Question:

Primary site/Histology: Do the 4/1/09 changes in the ICD-O-3 Site/Type Validation table regarding the coding of primary site for intestinal type adenocarcinoma mean that the former valid site/histology combinations are now impossible and require review from a given diagnosis date forward? See Discussion.

Discussion:

Per the SEER Errata for ICD-O-3 Site/Type Validation List, April 1, 2009, adenocarcinoma, intestinal type, was removed as a valid site/histology combination for the following primary sites: C150-C155, C158-C159, C170-C173, C178-C179, C180-C189, C199, C209, C210-C212, C218.

Does this mean that these combinations cannot be used? If so, then why is an override allowed for these site/type combinations? Shouldn't these site/type combinations be added to the impossible site/type combinations table?

SINQ 20081085 states that "8144/3 will be removed from the valid site/histology list for large intestine, small intestine, and rectum." It appears from the Site/Type Validation table that a decision was made to also remove esophagus sites as a valid combination with histology code of 8144. Please explain the rationale.

Cases that were miscoded to 8144/3 will need to be identified for correction. What date of diagnosis should be the reference point used in making the necessary corrections related to this change? Do we only need to review cases diagnosed 1/1/2009 forward or should all cases be corrected regardless of date of diagnosis?

Answer:

The site/type edit identifies unlikely combinations of primary site and histologic type.

Intestinal type adenocarcinoma occurs in the stomach. It would be rare in another primary site, but not impossible.

It was decided that all digestive organ sites, except stomach, would be removed from the list. That is why esophagus is not listed as a valid site.

The site/type edit is for all years. Cases for all years have to be reviewed for combinations of site and type that are no longer on the list. If it is documented in the medical record that the primary site and histology combination are valid, set the over-ride flag so that the case will not come up for review again.
