Revision status for remaining 2007 Multiple Primary and Histology site rules:
SEER is currently working on revisions to the remaining two MP/H site groups. Release date of the final sites has not yet been determined. Based on the recent WHO 4th Edition Tumors of Skin, SEER does not expect major changes to the cutaneous melanoma rules.
Other sites:
SEER identified the need to separate select sites into individual modules. These site-specific rules may be individual sections within the Other sites rules, or free-standing module. Revisions will be based on the following 4th Edition WHO Blue Books:
Tumors of Endocrine Organs
Female Reproductive Organs
Tumors of Soft Tissue & Bone
Tumors of Male Genital Organs (included in the Tumors of Urinary System Blue Book)
Education:
The Solid Tumor module will be added to SEER*Educate soon. We will notify the registrar community when the module is available. Additional educational modules will be developed and available through NCRA free of charge.
