Does a high Ki-67 score of 89 increase recurrence risk for stage 3 grade 2 triple-negative breast cancer after completing treatment?
While Ki-67 is a marker that indicates how quickly cancer cells are dividing, the search results don't specifically address how Ki-67 scores affect recurrence rates in TNBC. However, several factors related to your situation are relevant.
Stage 3 TNBC does carry a higher recurrence risk. People with stage 3 TNBC are 89 percent more likely to have a recurrence compared to those with earlier stages. Additionally, if cancer has spread to lymph nodes, the risk of relapse more than doubles.
The good news is that you've completed comprehensive treatment including chemotherapy, surgery, lymph node removal, and radiation. Achieving a pathologic complete response (no remaining cancer after treatment) significantly improves outcomes.
For TNBC overall, about 40 percent of people with stage 1-3 disease experience recurrence, with most happening within the first three years. However, if no recurrence occurs within five years, 97 percent remain relapse-free at 10 years.
Your oncology team can best interpret your Ki-67 score in the context of your complete pathology and treatment response. They may recommend closer monitoring during the first few years when recurrence risk is highest.
