Grade 1 ILC - response to chemo?

Chemist

I've just learned that my ILC is not responding to neoadjuvant hormone therapy (letrozole). I plan to have double mastectomy next week, then my medical oncologist recommends chemotherapy, even though she also says that Grade 1 ILC's rarely respond to chemo because they grow slowly. The alternative is to try to get into a clinical trial after surgery. If you have any stories of Grade 1 ILC tumors shrinking or even disappearing (i.e. pCR) with chemo before surgery, please let me know! That would raise my hopes that chemo might be worthwhile in my case. It could help very much in making my choice. Thank you!
