Treatment for DCIS

Hi, I had a lumpectomy for DCIS. Pathology reports state Extensive (multifocal) DCIS with focal minimal microinvasion, cribiform and micropapillary patterns, central necrosis, high N/C ratio, hyperchromasia, mitotic activity, tumor reaches margins at places. Tumor measures 3.5 cms in diameter.
My onco advised radiation therapy + hormones or MRM. Please advise on what is the appropriate treatment for this. Thanks

Hi,

Glad the post was of some help to you.

Like i said in my previous post, due to the constraints of using this form of communication, it would be wrong to make any comments on the finer aspects of your management.

You should discuss this in detail with your treating oncologist , because he/she would know your case the best, so that you are convinced about the plan of management in your case.

Let us know about how you are doing and if you have any other queries.

Hope this helps.

Good luck.

Thanks for your response.
I am 36 years old and I believe the tumor is intermediate grade and 3.5cms in size. Does this mean I am at high risk?
Will doing a re-exicision to obtain clear margins be an option? I have read about partial mastectomy or quadrant mastectomy. Would this be adequate in place of a MRM?
I have read that DCIS is a pre-cursor to breast cancer, which may or may not develop in the future. Why should one have to lose the complete breast then?
Thanks.

Hi,

The usual management plan in a case of DCIS is lumpectomy followed by radiation therapy and hormone therapy only if the hormone receptor status comes out to be positive.

The two options available are either mastectomy alone or lumpectomy plus radiation.  Radiotherapy is added to the lumpectomy because it decreases local recurrence rates by 50% compared to lumpectomy alone.

Lumpectomy alone, without subsequent radiotherapy, may be an appropriate treatment if the DCIS is considered to have a "low risk" of recurrence.

The risk of recurrence depends on certain factors such as size, tumor grade, age of patient and status of surgical margins.  "Low risk" refers to a tumor which is small, with low tumor grade, and negative surgical margin, occurring in older patients.

Discuss all your doubts with your treating oncologist too, because he/she would know your case the best, so that you are convinced about the plan of management in your case.

Let us know about how you are doing and if you have any other queries.

Hope this helps.

Good luck.
