Is Ki-67 Proliferation Index at all relevant

Ki-67 Proliferation Index Relevance for Josh's Case

Based on the document provided, Ki-67 proliferation index is not mentioned in Josh's clinical summary. However, I can address whether it would be relevant to his situation:

Why It Could Be Relevant

Ki-67 is a marker that measures how quickly cancer cells are dividing. According to NCCN Guidelines for Non-Hodgkin's Lymphomas, Ki-67 can help:

• Assess the aggressiveness of follicular lymphoma
• Help predict treatment response and prognosis
• Guide treatment selection

Since Josh has relapsed/refractory follicular lymphoma with documented disease progression, Ki-67 could potentially provide useful information about his tumor's behavior.

What the Document Shows Instead

The clinical summary notes that:

• Specific genomic mutations, BRCA status, IHC results, and methylation data are not provided in the available records
• Tissue from his recent splenectomy is available for molecular testing
• An upcoming biopsy is scheduled for [date removed]

Next Steps to Consider

Since Josh has tissue available and an upcoming biopsy, this would be an appropriate time to discuss with his oncology team whether comprehensive molecular profiling—which could include Ki-67 assessment—should be performed to help guide future treatment decisions.

I'd recommend Josh ask his care team directly about what biomarkers they plan to test on the upcoming biopsy tissue.
