Pathology Report Delays
I had an awake craniotomy June 2nd, but I still only have the initial microscopic result and my MGMT methylated results. This is the microscopic result:
- IDH1 p.R132H (D2): Positive
- ATRX (D2): Mosaic
- p53 Semi-quantitative (D2): Positive in rare cells, favor null
- Ki67 Semi-quantitative (D2): 3-5%
The current diagnosis is favored to be a Grade 2 Diffuse Astrocytoma, and they believe they were able to perform a gross total resection (based on the post-operative MRI). Because the ATRX was mosaic, they can't definitively say it's an Astrocytoma yet, but they believe it is.
For the MGMT, the reported values consists of:
- A methylation index, ranging from 0 to 17 that reflects the number of methylated CpG sites.
- A methylated fraction, ranging from > 0 to 1, that provides an estimation of methylation in the analyzed specimen (reported only for positive specimens).
- An overall methylation score ranging from > 0 to 17 that combines the methylation index and the methylation fraction (reported only for positive specimens).
My result is:
Value: Postive
Methylation Fraction: 0.986
Methylation Score: 13.81
Interpretation:
CpG methylation was detected in the MGMT promoter region.
This result indicates the presence of CpG methylation at the queried CpG sites in the promoter region of the MGMT gene in DNA isolated from tumor-enriched tissue of this individual’s paraffin section.
This is all I have so far, and it's about to be a month. Is this typical for detailed pathology reports? I am still waiting to know the results for: TP53, CDKN2A/B, ATRX (definitive results), and any other mutations.
I have been having to practice patience (and sometimes compartmentalization) as I wait for the results, but because my prognosis and treatment plan hinges on it, it's getting tougher day by day.
