Question:

MP/H Rules/Date of Diagnosis/Behavior--Brain and CNS: How many primaries would be reported when a December 2004 MRI shows a pineal region mass with the major differential consideration being pineocytoma; a November 2007 MRI that shows the mass has almost tripled in size; and the December 2007 resection final diagnosis is consistent with pineoblastoma? How would diagnosis date[s] and behavior code[s] be coded? See Discussion.

Discussion:

Dec. 2004 MRI of brain: Pineal region mass. The major differential consideration given patient's gender, age group, and imaging characteristics is pineocytoma. The differential includes pineoblastoma or germ cell line tumor. These are felt less likely.

Nov. 2005 MRI brain: stable exam since last MRI. No change in size.

Nov. 2007 MRI studies: pineal mass has almost tripled in size.

Dec. 2007 Surgical resection of pineal tumor: High grade (WHO Grade IV) pineal parenchymal neoplasm consistent with pineoblastoma.

Answer:

For cases diagnosed 2007 or later:

Abstract as separate primaries:

12/2004 pineocytoma (9361/1)

12/2007 pineoblastoma (9362/3)

Complete two abstracts when a previously diagnosed non-malignant tumor transforms or progresses to a malignancy. Refer to the CDC/NPCR guidelines for Data Collection of Primary Central Nervous System Tumors, 2004. Malignant transformation is discussed on page 50.
