Skin-sparing mastectomy. Oncologic and reconstructive considerations.

OBJECTIVE The authors compared skin-sparing mastectomy and traditional mastectomy both followed by immediate reconstruction in the treatment of breast cancer. SUMMARY BACKGROUND DATA Skin-sparing mastectomy is used increasingly in the treatment of breast cancer to improve the aesthetic results of immediate reconstruction. The oncologic and reconstructive outcomes of this procedure have never been analyzed closely. METHODS Institutional experience with 435 consecutive patients who underwent total mastectomy and immediate reconstruction from January 1989 through December 1994 was examined. Mastectomies were stratified into skin-sparing (SSM) and non-skin-sparing (non-SSM) types. RESULTS Three hundred twenty-seven SSMs and 188 non-SSMs were performed. The mean follow-up was 41.3 months (SSM, 37.5 months, non-SSM, 48.2 months). Local recurrences from invasive cancer occurred after 4.8% of SSMs versus 9.5% of non-SSMs. Sixty-five percent of patients who underwent SSMs had nothing performed on the opposite breast versus 45% in the group of patients who underwent non-SSM (p = 0.0002). Native skin flap necrosis occurred in 10.7% of patients who underwent SSMs versus 11.2% of patients who underwent non-SSMs. CONCLUSIONS Skin-sparing mastectomy facilitates immediate breast reconstruction by reducing remedial surgery on the opposite breast. Native skin flap necrosis is not increased over that seen with non-SSM. Skin-sparing mastectomies can be used in the treatment of invasive cancer without compromising local control.

Local Recurrence After Skin-Sparing Mastectomy: Tumor Biology or Surgical Conservatism?

Background:Long-term follow-up of the use of skin-sparing mastectomy (SSM) in the treatment of breast cancer is presented to determine the impact of local recurrence (LR) on survival.Methods:A total of 539 patients were treated for 565 cases of breast cancer by SSM and immediate breast reconstruction from January 1, 1989 to December 31, 1998. The American Joint Committee on Cancer pathological staging was stage 0 175 (31%), stage I 135 (23.9%), stage II 173 (30.6%), stage III 54 (9.6%), stage IV 8 (1.4%), and recurrent 20 (3.5%). The mean follow-up was 65.4 months (range, 23.7–86.3 months). Five patients were lost to follow-up.Results:Thirty-one patients developed a LR during the follow-up including five who received adjuvant radiation. The distribution of LR stratified by cancer stage was stage 0 1, stage I 5, stage II 17, stage III 6, and recurrent 2. The overall LR was 5.5%. Twenty-four patients (77.4%) developed a systemic relapse and 7 (22.6%) patients remained free of recurrent disease at a mean follow-up of 78.1 months. The cancer stage of those remaining disease free was stage 0 1 (100%), stage I 4 (80%), and stage II 2 (11.8%).Conclusions:LR of breast cancer after SSM is not always associated with systemic relapse.

A Meta-Analysis Comparing Breast Conservation Therapy Alone to the Oncoplastic Technique

AbstractWhen immediate reconstruction is applied to breast conservation therapy (BCT), the benefits extend well beyond the minimization of poor cosmetic results. The purpose of this analysis was to compare literature outcomes between BCT alone and BCT with the oncoplastic approach. MethodsA meta-analysis was performed in PubMed using key words “oncoplastic,” “partial breast reconstruction,” and “breast conservation therapy.” Case reports, series with less than 10 patients, and those with less than 1-year follow-up were excluded from the analysis. The 3 comparative groups included BCT with oncoplastic reduction techniques (Group A), BCT with oncoplastic flap techniques (Group B), and BCT alone (Group C). ResultsComparisons were made on 3165 patients in the BCT with oncoplastic group (Groups A and B, 41 papers) and 5494 patients in the BCT alone group (Group C, 20 papers). Demographics were similar, and tumor size was larger in the oncoplastic group (2.7 vs 1.2 cm). The weight of the lumpectomy specimen was 4 times larger in the oncoplastic group. The positive margin rate was significantly lower in the oncoplastic group (12% vs 21%, P < 0.0001). Reexcision was more common in the BCT alone group (14.6% vs 4%, P < 0.0001), however, completion mastectomy was more common in the oncoplastic group (6.5% vs 3.79%, P < 0.0001). The average follow-up was longer in the BCT alone group (64 vs 37 months). Local recurrence was 4% in the oncoplastic group and 7% in the BCT alone group. Satisfaction with the aesthetic outcome was significantly higher in the oncoplastic group (89.5% vs 82.9%, P < 0.001). ConclusionsThe oncoplastic approach to BCT allows a generous resection with subsequent reduction in positive margins. The true value on local recurrence remains to be determined. Patients are more satisfied with outcomes when the oncoplastic approach is used.

Management algorithm and outcome evaluation of partial mastectomy defects treated using reduction or mastopexy techniques

Background:Reconstruction of the partial mastectomy defect has become increasingly popular becaue of poor cosmetic results in select patients. The purpose of this series was to try to create a treatment algorithm based on patient selection, diagnosis, margins, and recurrence in an attempt to maintain oncologic safety, as well as to improve esthetic outcome. Methods:A retrospective review of all patients treated at Emory University Hospital with partial mastectomy and reduction/mastopexy was performed. Reconstruction was performed either simultaneously or following confirmation of negative histologic margins. Results:Sixty-three women were included in the series. Histology was invasive carcinoma (n = 33), ductal carcinoma in situ (DCIS) (n = 20), fibroadenoma (n = 6), and benign breast tissue (n = 4). The Wise pattern was used 84% of the time (n = 53/63). The most common tumor location was upper outer quadrant, and the various pedicles used were superomedial (n = 22), inferior (n = 20), central (n = 7), and other (n = 14). Eight patients had reduction/mastopexy once final pathology confirmed negative margins. The average biopsy weight was 236 g. Total specimen weight on the tumor side was 762 g and 858 g on the contralateral side, to accommodate for radiation fibrosis. Immediate complications were seen in 22% of cases and included delayed healing (n = 9), infection (n = 1), partial nipple loss (n = 1), hematoma (n = 1), and skin necrosis (n = 1). In patients with breast cancer (n = 53), 26% required either fine needle aspiration or excisional biopsy for cancer surveillance postoperatively. Oncoplastic surgery was the definitive procedure 93% of the time. Completion mastectomy with reconstruction was required in 4 patients, 3 for positive margins extensive DCIS and 1 for residual microcalcifications (stereobiopsy DCIS) despite adequate specimen radiograph and negative margins initially. All 4 patients who failed the combined approach were younger women with the diagnosis of extensive DCIS. The locoregional recurrence rate was 2%, and all patients had no evidence of disease at an average follow-up of 3.25 years. Conclusion:Therapeutic mammaplasty is a useful procedure for shape and symmetry preservation in women with large or ptotic breasts. Versatility exists using various pedicles and skin patterns to reconstruct all breast shapes and defect locations. Younger patients with extensive DCIS are poor candidates for simultaneous reconstruction, and should be deferred until confirmation of negative margins. If surgical management of residual disease requires completion mastectomy, immediate reconstruction is possible, with skin preservation and no adverse effects.

Sentinel node staging of early breast cancer using lymphoscintigraphy and the intraoperative gamma-detecting probe

Sentinel node staging for breast cancer is increasingly used in place of axillary lymph node dissection but is not yet universally accepted. The problems of non-standardized methodologies and lack of consensus on the optimum techniques to identify sentinel nodes are being addressed. Complementary use of radionuclide imaging before surgery, intraoperative probe detection, and blue dye have yielded the best reported sensitivities for finding a sentinel node (94%). The importance of imaging is summarized as identifying sentinel node(s), distinguishing sentinel from secondary nodes, guiding surgical incision planning, and facilitating lower doses. The learning curve phenomenon, which applies to the surgeon and the nuclear medicine physician, has been recognized; measures to minimize it are being implemented. Radiation exposure to operating room and pathology personnel is very low; estimates of exposure to the surgeons hands are 0.2% of the annual whole body dose received by every human being from natural background and cosmic sources.

The role of reduction mammaplasty in reconstructing partial mastectomy defects

&NA; The management of breast tumors in women with macromastia can be challenging. Reconstructive options are limited and breast conservation therapy is often not indicated or results in poor cosmetic outcomes. The purpose of this report was to present a series of women with macromastia who underwent simultaneous reconstruction of a partial mastectomy defect with bilateral reduction mammaplasty. A retrospective review was performed and included all women who underwent partial mastectomy with simultaneous reduction mammaplasty. Data points included patient demographics, preoperative assessment, operative intervention, adjuvant treatment, and outcomes. Twenty women were included in the series (mean age, 43 years; range, 11 to 72 years) with an average body mass index of 32.6 (range, 24.9 to 44.1). Tissue diagnosis was ductal carcinoma (n = 8), ductal carcinoma in situ (n = 6), fibroadenoma (n = 4), and benign breast tissue (n = 2). The various reduction mammaplasty techniques were documented with regard to tumor size and location. The superior medial and inferior pedicles seemed to be the most versatile techniques. One patient required completion mastectomy with autologous tissue reconstruction given positive margins. All patients were disease‐free at follow‐up (mean, 23 months) and postoperative cancer surveillance was not impaired by the combined procedures. The versatility of reduction mammaplasty allows this procedure to be performed in conjunction with partial mastectomy for any tumor location. Combining these procedures in patients with macromastia provides numerous therapeutic benefits at low cost, while reducing breast distortion and preserving symmetry. (Plast. Reconstr. Surg. 109: 968, 2002.)

The impact of partial breast reconstruction using reduction techniques on postoperative cancer surveillance.

Background: Partial breast reconstruction using reduction techniques has recently increased in popularity. Some fear that combining breast conservation therapy with partial breast reconstruction alters the architecture and will affect patterns of local recurrence and make postoperative cancer surveillance more difficult. The purpose of this series was to evaluate long-term postoperative cancer surveillance. Methods: The authors retrospectively reviewed the charts and mammograms of patients (n = 17; average follow-up, 6.3 years) who underwent the oncoplastic reduction technique before 2004. Mammography sensitivity was determined by measuring breast density, qualitative changes, and time until mammographic stabilization was determined. These data were compared with those of a control group from the same time period who underwent breast conservation therapy alone (n = 17; average follow-up, 5.9 years). Results: Typical mammographic findings, including architectural distortion, cysts, and calcifications, were similar between the two groups. There was no significant difference in breast density scores. The oncoplastic reduction group had longer times to mammographic stabilization (21.2 versus 25.6 months, p = 0.23). There was a trend toward a greater number of postoperative mammograms and ultrasounds in the study group when indexed per follow-up year. The rate of tissue sampling in the study group was significantly higher (53 percent) than that in the control group (18 percent). Conclusions: The oncoplastic reduction technique remains safe and effective, without significantly affecting postoperative surveillance. Mammographic findings were similar to those observed in patients with breast conservation therapy alone, and sensitivity was not affected. It takes longer to achieve mammographic stability and more patients in the oncoplastic group will require additional diagnostic testing.

Preservation of the Inframammary Fold: What Are We Leaving Behind?

&NA; Preservation of the inframammary fold (IMF) at the time of mastectomy facilitates immediate breast reconstruction. Twenty‐four IMF specimens were removed separately after mastectomy for cancer, were serially sectioned, and were examined histologically. Computer image analysis was used to calculate the percentage of breast tissue in each specimen. The mean volume of IMF tissue removed was 99 cm3 (27.3‐205.2 cm9), and the mean area examined histologically was 3,036.3 mm2 (294‐11,755 mm2). Breast tissue was identified in 13 of the 24 specimens. All cases were negative for carcinoma, but one case had a focus of ductal hyperplasia, usual type. The mean percent breast tissue in those positive for breast tissue was 0.04 percent and 0.02 percent overall. Preservation of the IMF leaves a minimal amount of breast tissue and does not appreciably effect the completeness of a mastectomy. (Plast. Reconstr. Surg. 98: 447, 1996.)

Immediate breast reconstruction for stage III breast cancer using transverse rectus abdominis musculocutaneous (TRAM) flap

AbstractBackground: The management of stage III breast cancer is challenging; it often includes multimodal treatment with systemic therapy and/or radiation therapy and surgery. Immediate breast reconstruction has not traditionally been performed in these patients. We review the results of immediate transverse rectus abdominis musculocutaneous (TRAM) flap in 21 patients treated for stage III breast cancer. Methods: Data have been collected retrospectively on 21 patients diagnosed with stage III breast cancer between 1987 and 1994. All patients had mastectomy and immediate TRAM reconstruction. Thirteen patients received primary systemic therapy, 10 patients received postoperative consolidation radiotherapy to the operative site, and 3 patients received preoperative radiation. Results: Mean follow-up for the group was 26 months. Two patients died with disseminated disease: neither of them developed local disease recurrence in the operative site; 82% of the patients followed for at least two years are free of disease. Sixty-two percent of the patients received preoperative chemotherapy, the remaining patients received postoperative multiagent chemotherapy and/or radiation therapy. Two of the patients received autologous bone marrow transplants after their adjuvant therapy. Ten patients had postoperative radiotherapy for consolidation; three patients received preoperative radiation. Conclusions: Immediate TRAM reconstruction for stage III breast cancer is not associated with a delay in adjuvant therapy or an increased risk of local relapse. It facilitates wide resection of involved skin without skin grafting. Radiation therapy can be delivered to the reconstructed breast when indicated without difficulty. Breast reconstruction facilitates surgical resection of stage III breast cancer with primary closure and should be considered if the patient desires immediate breast reconstruction.

Three-Dimensional Digital Evaluation of Breast Symmetry after Breast Conservation Therapy

BACKGROUND Breast conservation therapy is proved as efficacious as modified radical mastectomy in the treatment of early-stage breast cancer. Although cosmesis is widely considered an advantage to this approach, objective evaluations of esthetic results are sparse. STUDY DESIGN Twenty-three patients were subjected to three-dimensional, digital imaging of their breasts using a 3dMD camera (3Q Corporation). Differences in volume and surface area were assigned an asymmetry score based on software calculations. Additional variables were queried, and results were compared with a control group of 35 age-matched patients. RESULTS Mean asymmetry score for the control population was 3.02 and for the breast conservation therapy population was 4.59 (p = 0.001). There was a positive correlation between percentage of breast parenchyma excised and asymmetry (p = 0.036). The location of the cancer, age of the patient, and need for multiple operations did not influence cosmetic results. CONCLUSIONS Breast conservation therapy appears to affect breast symmetry when evaluated objectively using three-dimensional imaging. In this series, the degree of asymmetry is related to the amount of tissue resected in relation to the breast volume but not on the location of the tumor, age of the patient, or need for reoperation.
