Statistics - recurrence

Aloha!

I'd appreciate any links to studies about Tamoxifen and AI's.  I've done some research but don't always remember to bookmark them.    I think I saw I have something like a 65%?? chance of being around in 10 years if I don't have hormonal therapy.   My Oncotype DX test (16) said I have a 90% chance of being around in 10 years without distant recurrence with tamoxifen and I've read AI's make that a 93% chance.    It seems most studies I've seen compare tam & AI's.   I can't remember any that also includes statistics for no hormonal therapy but they must be out there!    

I'd like links because an alternative MD I've consulted with doesn't believe those statistics and wants to see studies.  I only had a lumpectomy when I first had breast cancer stage 1 in 2004.  I opted out of everything else.   At that time there was a calculator on Mayo Clinic which said I had a 90% chance of being around in 10 years with no adjunctive therapy (did not give a statistic for recurrence though and I knew it was higher) and 93% of being around with adjunctive therapy.

 This time I had a bi-lateral mastectomy (started with a lumpectomy, the mammogram & ultrasound only "saw" .10 cm and the tumor was 2.5 cm - so I wanted both breasts gone!).   I'm still trying to decide on tamoxifen or AI (that my onc recommends.)   Onc & primary did not suggest I get estrogen tests ... but I managed to get them ordered.   The urine test shows me very very low in estrogens.   Waiting for estrogen saliva & blood test results.   If my estrogen tests all agree, I doubt I will try AI's.   I would then look at tamoxifen but would want to take whatever test it is that determines if it will be helpful.      I am 70.  

I also posted this on another forum.

I have gone the alternative route as much as possible so far.    I have 2 alternative MD's I consult with plus recently had several appointments with a Naturopath. 

Mahalo for any clarification!
