Should you stop Pola-R-CHP chemotherapy early after 3 cycles if your PET/CT scan is negative?
Standard treatment for advanced DLBCL with Pola-R-CHP involves six cycles. This is the FDA-approved regimen that showed better outcomes in clinical trials.
While a negative PET scan after 3 cycles is encouraging news, it's important not to stop treatment early without discussing it thoroughly with your oncologist. Here's why:
- Completing the full course helps ensure all cancer cells are eliminated, even microscopic ones that scans might miss
- DLBCL relapses are most common within the first two years after treatment
- Stopping early could increase your risk of the lymphoma returning
Your oncologist will consider several factors when making treatment decisions:
- Your specific DLBCL subtype
- How well you're tolerating the side effects
- Your overall health and risk factors
- The scan results and your complete response
If side effects are making treatment difficult, talk with your doctor about managing them rather than stopping treatment. Your first obligation is to give yourself the best chance for long-term remission.
This is definitely a conversation to have with your healthcare team before making any changes to your treatment plan.
