Surgical Treatment of Breast Cancer in Previously Augmented

This article by Karanas and colleagues addresses
the increasingly important topic of the
treatment of breast cancer among previously
augmented women. This study reviewed the
outcomes for 58 augmented patients with
breast cancer who were treated between 1991
and 2001. Just over one-half of the patients (30
patients) were treated with mastectomy. Of
those patients, 29 underwent breast reconstruction.

The authors did not focus on the
mastectomy/reconstruction group. However,
there is little reason to think that implants
would interfere with mastectomy and/or breast
reconstruction. In fact, it is conceivable that
previous breast augmentation might even facilitate
reconstruction, because the mastectomy
flaps have been surgically “delayed” to some

The focus of this article was on augmented
patients with breast cancer who underwent
breast conservation therapy. It has been established
that breast conservation therapy can be
effectively administered to patients with implants.
1–3 However, there are conflicting data
with regard to the cosmetic outcomes and complication
rates in these cases. Some authors
have noted that patients with implants who
undergo radiotherapy enjoy good cosmetic results,
4–6 whereas others have observed high
rates of contracture and poor cosmetic

Among the 28 patients in this study who
chose breast conservation therapy, some underwent
implant removal at the time of
lumpectomy and some did not complete the
full course of radiotherapy. However, a total of
19 patients completed breast conservation
therapy with their implants in place. Among
this group, a large proportion (58 percent)
experienced significant complications related
to radiotherapy. These complications included
capsular contracture, poor cosmesis, pain, erosion,
an intractable seroma, and rupture.

The relatively poor outcomes observed for
these augmented patients who underwent
breast conservation therapy confirm findings
previously reported by our group 9,10 and others.
In 1996, we reported on the use of breast
conservation therapy for 33 augmented patients
with cancer.10 Complete follow-up data
were available for 26 of those patients. Most of
those patients experienced poor cosmetic outcomes,
and the majority (65 percent) developed
clinically significant capsular contracture
on the irradiated side. A large proportion
(>30 percent) of our augmented patients who
underwent breast conservation therapy required
surgical revisions. Some required multiple
attempts at capsulotomy/capsulectomy
and reimplantation, in efforts to achieve satisfactory

The current study adds to the growing body
of literature suggesting that complications are
frequent and cosmetic outcomes are suboptimal
when previously augmented patients with
breast cancer undergo breast conservation
therapy. However, it is important to remember
that cosmetic results following breast conservation
therapy are very “technique dependent”
(for both augmented and nonaugmented patients).

The authors provided no details with
regard to the radio therapeutic techniques
used in these cases, stating that “data regarding
the exact dosages and fields of irradiation were
incomplete.” It is difficult to understand why
treatment details were unavailable, because the
authors claimed that they reviewed the records
of the Revlon/UCLA Breast Center and medical
records from other institutions. Because of
the importance of technique, studies evaluating
outcomes following breast conservation
therapy must consider the doses and fractions
of radiation administered, the number of treatments
given to each patient, and the total
whole-breast doses. It is also important to consider
details regarding the boost to the tumor
