Hi Everyone,

I'm writing on behalf of my family member with the following diagnosis:

- IDC, ER-/PR-, HER2+, Grade 3

- on TCHP reigmen

- Original ultrasound: 1.3 x 1.0 x 1.1 cm

- Ultrasound halfway through TCHP reigmen: 1.2 x 0.5 x 0.9 cm

We're not sure how to interpret these results - the overall volume of the tumor has shrunk by over 60% but the longest diameter of the tumor doesn't seem to have decreased much(1.3 to 1.2cm) With 3 more rounds of TCHP to go, can anyone provide input on what this response looks like? It seems like in most literature and posts here most people refer to their tumor size as just one number(longest diameter?) Has anyone had a similar response halfway through this regimen and what were your next steps?

Any insight on this would be greatly appreciated as it's been very hard to find info on this subject. Thanks so much!
