When
buying a car, do you compare model specifications within a budget
range? If faced with breast cancer, would you similarly scrutinize the
options? Hope so. Doctors are too fallible to bear the entire burden.
This job is tough enough as it is.
Biopsy of a suspicious breast mass may be accomplished by needle
sampling or by open excisional biopsy. When needle sampling is done, a
"fine" aspiration biopsy will confirm the presence of malignant
cells while a "core" can diagnose invasion and provide
tissue
for further processing. As to open biopsy, if ever excision is
contemplated within the context of a possible cancer, marking of margins or the inclusion of a rim of normal
tissue around the mass must be done where feasible (in effect, a
lumpectomy). This is to minimize the need for further radical surgery.
If the breast mass biopsy is positive, staging is done &
treatments are planned accordingly. (How I hate it when stage IV patients have wasted time & money on pointless radical surgery before they get the treatment they really need!) The staging tests ordered would
depend on a thorough history & physical examination, but chest
x-rays, mammography, a bone scan, liver ultrasound, or CT scans may be
requested. Special stains are sometimes done on the biopsy specimen at
this point for hormone receptor assays & her2/neu (cerbB2) growth
factor receptor, especially if preoperative treatments are contemplated.
In non-metastatic invasive breast cancer of the non-inflammatory type, an operation is
always a component of cure. For
stages I & II,
Breast Conserving Surgery is ideal in the absence of any compelling
contraindication. BCS, aka "lumpectomy" or "partial mastectomy",
involves a wide excision of tumor with a cuff of normal tissue around
it. It entails subsequent radiotherapy but affords the same control
rates as a standard modified radical mastectomy with better cosmetic
results. A better feel & shape than an implant in most cases
anyway. (By the way, while there are additional technical
considerations, BCS is not prohibited for tumors near the nipple or
where implants are in place.) Axillary lymph node sampling is also done
with BCS, through a separate armpit incision. This sample extent
depends upon whether you've presented with apparent node involvement or
not. If none are clinically evident, just a biopsy of the "sentinel
node" may be done. Axillary node status is just prognostic and not all
nodes need to be removed. The extent of their involvement gives your
docs added staging information to guide postoperative treatments.
What should make you think twice about lumpectomy? When is a
modified radical mastectomy the better option? Well, BCS requires
re-excision should the margins of the lumpectomy specimen remain
positive. Radiotherapy is a necessary component, so those who can't
take that treatment are best served by breast removal (eg. early
pregnancy). BCS is also suboptimal if tumors are multiple. The same is
true if the mass is large relative to the breast's size, although
preoperative (neoadjuvant) chemotherapy may be considered to enable BCS
in such cases.
Where all things are equal and no contraindications to BCS exist, the important factor is the
fully informed patient's preference.
As for surgeons… I know of a busy one who said that breast cancer
operations are glorified excisions to sleepwalk through. For a minute
there, I'd thought that I was talking with God (or a neurosurgeon) but…
no; This doc still comes alive for each hair-raising Whipple's
procedure. Would that all constructive thrill-seekers have that level
of experience & expertise, not to mention stamina. In reality, what
may be almost reflexive & forthright for some is an uncommonly
complex job for others. Find yourself an oncology team with a great
surgeon!
Really nice post. I LOVE IT.
