Inquiry Details
References:
WHO Class Tumors of the Eye, 118-120. 4th edition
Question:
Reportability--Retina: Is a diagnosis of retinal astrocytoma reportable? See Discussion.
Discussion:
There is no specific ICD-O-3 code for a which resulted in abstractors assigning the malignant astrocytoma, NOS code. These lesions were previously called but we are seeing the new terminology more frequently.
Answer:
Report retinal astrocytoma. The WHO Classification of Tumors of the Eye, 4th edition, lists astrocytoma, NOS as 9400/3 with astrocytic hamartoma of the retina as a synonym. You may receive a site/type edit (IF25) which can be overridden.
The changes in terminology, codes, etc. proposed in WHO 4th Ed Eye book were implemented for cases diagnosed 1/1/2018 forward. Apply this to retina astrocytomas and do not accession cases diagnosed with this histology prior to 1/1/2018.
