I was recently diagnosed with ILC that is ER+, PR-. I am told PR negative is rare for this type of cancer. Anyone out there with a similar diagnosis? What type of treatment did you receive?

I have not received HER yet, initial results were inconclusive. Thanks in advance for your replies.

I have the same diagnosis. I had a lumpectomy followed by 4 rounds of T/C chemo. My last chemo was March 27th. I was not aware that this diagnosis was rare.

Hi

my dx through oncotype was er+pr-her2_. My lumpectomy pathology was er+pr+her2-. So, not entirely sure.... although I do think pathology trumps the oncotype--anyway 4 rounds of A/C, radiation, anti-hormonals and her I am almost 9 years later.....

HI

It's fairly uncommon for ILC to be PR- (but not really rare, rare is triple negative ILC). There are a few of us that are PR- on a Facebook ILC group. It means you're likely (but not definitively) to be classed Luminal B. Means more aggressive type, but responds better to chemo than luminal A type, and responds better to Letrozole (as opposed to Tamoxifen). That has been my understanding from reading and researching relevant articles (scientifice/medical) on the internet. . I did 4 AC, followed by 3 Taxol (had to stop due to bad reaction), then 3 Taxotere, 25 rads and now on Femara and Zometa, indefinitely. Just to be very clear - I am not a doctor, just someone who reads up as much as possible to try and understand my diagnosis and its implications for treatment.
