I appreciate you sharing that your gallbladder cancer is HER2-positive. That's important information.

Here's what I can tell you:

The guideline excerpts I have show that HER2-targeted therapies (like Enhertu) have shown promise in gastric and other GI cancers when HER2 is present. The data demonstrates that patients with high HER2 expression treated with anti-HER2 therapy can have significantly better outcomes.

However, I don't have specific second-line Enhertu data for gallbladder cancer in my current resources.

What matters for your situation:

Your oncologist needs to evaluate:

Your specific HER2 expression level (not just positive/negative)
What first-line treatment you received and how you responded
Whether there's clinical trial data or real-world evidence for Enhertu in your exact scenario
How this compares to other second-line options available to you

To get the best answer: Ask your oncologist directly about Enhertu efficacy data for HER2-positive gallbladder cancer in the second-line setting. They'll have access to the latest NCCN Guidelines and clinical evidence for your specific case.
