Collection and usage attributes
|Guide for use:|
Record the appropriate code at the time of diagnosis.
Origin of primary site is on the right side of a paired organ.
Origin of primary site is on the left side of a paired organ.
Origin of primary site is on both sides of a paired organ. (When tumours of the same morphology are diagnosed simultaneously in both sides of a paired organ.)
Includes organs that are bilateral as a single primary (e.g. bilateral retinoblastoma (M9510/3, C69.2), (M9511/3, C69.2), (M9512/3, C69.2), (C69.6, C48.0), bilateral Wilms tumours (C64.9, M8960/3))
Note: Bilateral cancers are very rare.
It is unknown whether, for a paired organ the origin of the cancer was on the left or right side of the body.
Paired organs and structures
The valid International Classification of Diseases for Oncology values for paired organs are provided in the list below:
|Collection methods:||This information should be obtained from the patient's medical record and pathology report.|
|Comments:||The laterality of the primary tumour may have implications for treatment and prognosis, and can be of assistance to cancer registries for the coding of subsequent tumours in paired organs.|
