For the surgery shelf, are there any situations in which a mammogram would not be indicated for the evaluation of a breast mass other than in women younger than 30 or lactating/pregnant?

It seems to me that all masses in women over 30 and who are non-lactating should be assessed with mammogram first, even if the mass is recurrent following a lumpectomy with radiation. But that brings to my mind this situation:

A woman with no mammographically-evident abnormalities for the past 2 years (4 mammograms) following a lumpectomy with radiation gets a palpable mass. Do we still go for a mammogram first?

In a woman with a mastectomy.

It is ESPECIALLY important in a woman with a recurrent mass after breast conservation (ie, not "even if...").

Yep, mammo with prn US.

There was some discussion as to whether you should biopsy first and then get the imaging study for palpable masses. See the thread in the Step 2 forum where we discuss this.

And why are you getting biannual mammograms (you mention 4 in 2 years)?

Thanks! I remember that thread and was looking for it but couldn't recall the title nor where it was. As I was chugging along my reading of NMS Case Book, it mentioned going straight to core needle or excisional bx for a recurrent mass s/p MRMwith subsequent staging, but I misread what it said for a recurrent mass s/p lumpectomy. I guess that's how I got that "even if" clause in there.

As far as biannual mammo's after lumpectomy, I got that from the NMS Case Book as well. Additionally, according to the American Cancer Society, they say that some "experts" prefer mammo's every 6 months for 2-3 years, although I couldn't find any guidelines for imaging after breast conservation surgery.

What's your practice for follow-up mammo's?
 
Would you recommend more or less frequent?

I think q 6 months seems to be what a lot of OB/gyns are recommending for "observation" purposes in certain patients.

I also see many Ob-Gyns also recommend baseline mammograms at age 35 without any risk factors or guidelines which recommend that.

MY feeling and the recommendations of the American Society of Breast Surgeons is a 6 month follow-up mammogram +/- US (I always order it because you'll see a persistent seroma on mmg and will need the US) of the affected breast after surgery is sufficient. After that, once again in 6 mo to get back on schedule for annual mammography. All the old recommendations are based on the highest risk of recurrence being in the first two years, but now as patients are living longer with their disease, we are seeing distant recurrences, 10-15+ years out. Are you going to be imaging these patients that far out every 6 mos? So a fair bit of dissention in the ranks about this.

However, in particularly high risk pops - BRCA and pre-menopausal patients, they should probably be followed more closely - those get annual mmg/us and MRI, separated by 6 months, along with twice yearly clinical breast examination. The fact is that in post-operative young patients, even digital imaging is not often sensitive enough to see something every 6 mos.

I wouldn't fault someone for getting q6mo mmg after breast cancer but there is no data to support it. These patients are generally over tested, and so frequently examined (especially when Med Oncs are getting PETs anyway) that the MMG more frequently doesn't add much, IMHO.

YW.

As I was chugging along my reading of NMS Case Book, it mentioned going straight to core needle or excisional bx for a recurrent mass s/p MRMwith subsequent staging,

For a mastectomy patient (and remember, not all mastectomies are MRM), it IS appropriate to go straight to biopsy as mammograms are not indicated. Most of these recurrences are going to be found by clinical breast exam and will be in the skin or along the scar, so imaging isn't really going to help you in terms of biopsy.

If the patient has implant reconstruction, I sometimes prefer imaging with US prior to biopsy as examination in relationship to closeness to the implant can be deceiving. But I have my own US in office, so its a bit of a different situation in which the average surgeon does not.

I got questioned about that on my oral boards as they quizzically looked at me when I mentioned using US for a palpable mass. My defense (which apparently worked) was that:

a) documents exactly where I am in the breast and mass
b) documents that the biopsy was actually done
c) documents procedure for US certification
d) shows placement of titanium clip

As we discussed in the other thread, what is done in clinical practice is not what is necessarily on the exam. For example, in almost no cases is it appropriate to do an excisional biopsy when a needle biopsy can be done. However, it is the "Safe Answer" so you cannot be faulted for choosing excisional biopsy unless needle is another option.

...but I misread what it said for a recurrent mass s/p lumpectomy. I guess that's how I got that "even if" clause in there.

As far as biannual mammo's after lumpectomy, I got that from the NMS Case Book as well. Additionally, according to the American Cancer Society, they say that some "experts" prefer mammo's every 6 months for 2-3 years, although I couldn't find any guidelines for imaging after breast conservation surgery.

That is because they don't really exist in any formal fashion. It is true that "some" prefer q6 mo imaging x 2 years and then yearly after, and it is true that "some" prefer clinical follow up q6 mo. These are probably the safe answers but the ACS doesn't always reflect data or what everyone does. I'd say for purposes of the exam, if that's what NMS says to do, you won't be faulted, as its better to be more conservative than miss something, but there's no evidence that these frequent mammograms in post-operative patients make a difference. The typical recurrence, especially early in patients on hormonal blockade or after chemo, is palpable.

What's your practice for follow-up mammo's?

See above post. Depends on the patient, but two in the first year and then yearly after that. Usually the med oncs are getting PETs anyway and sometimes MRIs on the chemo patients and/or young patients so I don't find the additional MMG adds anything.
 
As always, you're awesome WS! This book is quite dated and some of the information here contradicts the current practice, so I was wondering about which management plan is the best way forward.

Thanks for shedding light on this.

As a side note, it sure would be helpful if the Step 2 actually reflected accepted medical practice.
