Appropriate use of magnetic resonance imaging and ultrasound to detect early silicone gel breast implant rupture in postmastectomy reconstruction.

BACKGROUND: Implant rupture is one of the most important sequelae of breast reconstruction after mastectomy. The primary aim of this study was to compare magnetic resonance imaging and ultrasound evaluation with intraoperative findings and provide a reliable description of the occurrence of each radiological sign. METHODS: The authors prospectively recruited a consecutive series of 102 postmastectomy patients requiring implant change for aesthetic purposes. Magnetic resonance imaging and ultrasound evaluation results were compared with intraoperative findings. Sensitivity, specificity, positive predictive value, negative predictive value, and the overall accuracy of magnetic resonance imaging and ultrasound in detecting ruptured implants were calculated, along with their corresponding 95 percent confidence intervals. RESULTS: Magnetic resonance imaging performs better than ultrasound for diagnosis of breast implant rupture, with overall accuracies of 94 and 72 percent, respectively. The negative predictive value of ultrasound was 85 percent, meaning that in the case of negative ultrasound findings, magnetic resonance imaging may be avoided. Teardrop sign and water droplets are the most common findings on magnetic resonance imaging. CONCLUSIONS: Magnetic resonance imaging should be considered the method of choice for investigating silicone gel implant rupture in postmastectomy patients, and the standardization of magnetic resonance imaging criteria may improve magnetic resonance imaging accuracy. The authors therefore suggest a strategy of screening asymptomatic women with ultrasound every year and with magnetic resonance imaging every 5 years.

Oncological safety of autologous fat grafting after breast conservative treatment: a prospective evaluation.

Autologous fat graft to the breast is a useful tool to correct defects after breast conservative treatment (BCT). Although this procedure gains popularity, little is known about the interaction between the fat graft and the prior oncological environment. Evidences of safety of this procedure in healthy breast and after post-mastectomy reconstruction exist. However, there is paucity of data among patients who underwent BCT which are hypothetically under a higher risk of local recurrence (LR). Fifty-nine patients, with prior BCT, underwent 75 autologous fat graft procedures using the Coleman's technique, between October 2005 and July 2008. Follow-up was made by clinical and radiologic examination at least once, after 6 months of the procedure. Mean age was 50 ± 8.5 years, and mean follow-up was 34.4 ± 15.3 months. Mean time from oncological surgery to the first fat grafting procedure was 76.6 ± 30.9 months. Most of patients were at initial stage 0 (11.8%), I (33.8%), or IIA (23.7%). Immediate complication was observed in three cases (4%). Only three cases of true LR (4%) associated with the procedure were observed during the follow-up. Abnormal breast images were present in 20% of the postoperative mammograms, and in 8% of the cases, biopsy was warranted. Autologous fat graft is a safe procedure to correct breast defects after BCT, with low postoperative complications. Although it was not associated with increased risk of LR in the group of patients studied, prospective trials are needed to certify that it does not interfere in patient's oncological prognosis.

The oncologic outcome and immediate surgical complications of lipofilling in breast cancer patients: a multicenter study--Milan-Paris-Lyon experience of 646 lipofilling procedures.

BACKGROUND: Lipofilling is now performed to improve the breast contour, after both breast-conserving surgery and breast reconstruction. However, injection of fat into a previous tumor site may create a new environment for cancer and adjacent cells. There is also no international agreement regarding lipofilling after breast cancer treatment. METHODS: The authors included three institutions specializing in both breast cancer treatment and breast reconstruction (European Institute of Oncology, Milan, Italy; Paris Breast Center, Paris, France; and Leon Berard Centre, Lyon, France) for a multicenter study. A collective chart review of all lipofilling procedures after breast cancer treatment was performed. RESULTS: From 2000 to 2010, the authors reviewed 646 lipofilling procedures from 513 patients. There were 370 mastectomy patients and 143 breast-conserving surgery patients. There were 405 patients (78.9 percent) with invasive carcinoma and 108 (21.1 percent) with carcinoma in situ. The average interval between oncologic surgical interventions and lipofilling was 39.7 months. Average follow-up after lipofilling was 19.2 months. The authors observed a complication rate of 2.8 percent (liponecrosis, 2.0 percent). Twelve radiologic images appeared after lipofilling in 119 breast-conserving surgery cases (10.1 percent). The overall oncologic event rate was 5.6 percent (3.6 percent per year). The locoregional event rate was 2.4 percent (1.5 percent per year). CONCLUSIONS: Lipofilling after breast cancer treatment leads to a low complication rate and does not affect radiologic follow-up after breast-conserving surgery. A prospective clinical registry including high-volume multicenter data with a long follow-up is warranted to demonstrate the oncologic safety. Until then, lipofilling should be performed in experienced hands, and a cautious oncologic follow-up protocol is advised. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV [corrected].

The value of latissimus dorsi flap with implant reconstruction for total mastectomy after conservative breast cancer surgery recurrence.

Total mastectomy is usually indicated after breast conservative treatment cancer recurrence. Breast reconstruction in this group can be performed with many options. We did 63 latissimus dorsi flap with implants reconstructions between 2001-2007. All of them were performed in breast cancer recurrence cases after breast conservative treatment and preceded for total mastectomy. The patient age range from 31 to 71 years old (50.1 ± 7.3 years). The follow-up was 36.5 ± 14.9 months (22-141 months). Neither flap loss nor significant major donor-site complication was recorded. The capsular contraction Baker's grade III was observed in 2 cases (3.1%). The rest were grade I-II and there was no grade IV contracture. We purpose that LD flap with implant can be performed in irradiated breast with low capsular contracture rate. It is suitable in total mastectomy reconstruction after conservative breast cancer surgery recurrence.

Impact of medical discipline and observer gender on cosmetic outcome evaluation in breast reconstruction using transverse rectus abdominis myocutaneous (TRAM) flap and radiotherapy.

BACKGROUND: Despite the complication rate, the majority of studies report a satisfactory cosmetic outcome in patients undergoing transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction both before and after radiotherapy (RT). The lack of a universal agreement on the use of a validated scale for cosmetic assessment in clinical practise leads to subjective criteria of evaluation and causes a great deal of interobserver variability. This study investigates whether there is any difference in the evaluation of cosmesis according to gender and specialisation of the observer. METHODS: Fifty-two photographs of the patients who had undergone TRAM reconstruction for breast cancer, divided into three groups according to the treatment (TRAM only, TRAM→RT, RT→TRAM), were evaluated by 21 specialists, 10 male and 11 female from radiotherapy, breast surgery and plastic reconstructive surgery. Cosmetic outcome was classified using the four-category Harvard scale: a score of excellent/good was considered acceptable. RESULTS: The overall rate of good/excellent ratings was 66.6%, which was lower than the score reported in the literature. A significantly worse score was registered in the TRAM→RT group compared with the other groups. The probability for male physicians to award a positive judgement is 24% higher than that of female ones. In general, there is a decent agreement among the judgement raters. CONCLUSIONS: No statistically significant difference in cosmetic evaluation was noted overall between male physicians and female ones. However, within each specialisation, the difference between the two genders was great. Breast surgeons gave the worst opinion, and among them female surgeons judged most severely, whereas plastic surgeons gave the best opinion, and among them females provided the highest favourable judgement.

Immediate breast reconstruction in the elderly: can it be considered an integral step of breast cancer treatment? The experience of the European Institute of Oncology, Milan.

BACKGROUND: In the last few decades, breast reconstruction often has not been offered to the elderly population due to the reluctance of clinicians concerned about serious co-morbidities. This study aims to demonstrate that breast reconstruction is feasible and safe in the elderly cohort. METHODS: Between 1999 and 2004, 63 elderly patients underwent an immediate reconstruction after breast cancer treatment at the European Institute of Oncology. A conservative treatment, combined with breast repair by plastic surgical techniques, was performed in 14 patients. In the remaining 49 patients, a modified radical mastectomy was necessary in 30 breasts, a total mastectomy in 19, a subcutaneous mastectomy in one case and a radical mastectomy in one patient. Three nipple-sparing mastectomies, along with intra-operative radiotherapy, were performed in two patients. A definitive silicone implant was used in 41 breasts and a skin expander in eight cases. A latissimus dorsi flap was performed in two patients, a pedicled transverse rectus abdominis muscle (TRAM) flap in two cases and a local advancement fasciocutaneous flap in another two patients. RESULTS: In all patients, surgery was well tolerated despite patient age. No systemic and medically unfavourable events occurred in the immediate and late postoperative period. Infection occurred in four patients (6.34%) and partial necrosis of the mastectomy flaps in three cases (5.5% of the mastectomies). Capsular contracture grade III and IV was reported in four cases (8.89%). Total implant removal was rated 12.24%, due to infection (three prostheses), exposure (one expander) and capsular contracture grade IV (two implants). CONCLUSIONS: Implant-based technique of breast reconstruction should be made available to the elderly population.

Sentinel node biopsy in patients with previous breast aesthetic surgery.

BACKGROUND: Sentinel lymph node biopsy (SLNB) is the standard method for axillary staging of early breast cancer. Recent studies have focused on questioning the initial contraindication to the technique. There has been insufficient data to recommend SLNB in patients with previous aesthetic breast surgery. MATERIALS AND METHODS: Between April 2001 and June 2007, 70 patients with previous breast aesthetic surgery underwent SLNB. Fifty had a previous breast augmentation and 20 had breast reduction mammoplasty. All patients underwent lymphoscintigraphy with 99Tc according to our standard technique and sentinel node was identified in all cases. RESULTS: Mean age at cosmetic surgery was 38 years. Mean number of years from aesthetic surgery to the development of the tumour was 10 years. Forty-nine patients underwent conservative breast surgery and 21 patients underwent mastectomy. The sentinel node identification rate was 100%. SLN was positive in 23 patients (32%); there were 18 cases with macrometastasis and 7 cases with micrometastasis. After median follow-up of 19 months, no axillary recurrences have been observed. We observed two ipsilateral local recurrences, one contralateral tumour and one patient developed lung metastasis. CONCLUSIONS: Past history of breast augmentation or reduction is not a contraindication to SLNB technique.

Surgical closure of chest wall in noninflammatory locally advanced breast carcinoma with ulceration of the skin.

Patients with noninflammatory locally advanced breast cancer with ulceration of skin or muscle or parietal wall infiltration, better named "extended locally advanced breast cancer," may require cancer surgery and plastic reconstruction of the chest wall after multidisciplinary evaluation. The decision is made to improve quality of life, independently of prognosis, and severity of the disease. The aim of this study is to evaluate the best method for surgical closure of the chest wall and to check whether ablative surgery is an appropriate procedure in regards to the treatment of cancer. From October 1997 to June 2006, 27 patients with noninflammatory extended locally advanced breast cancer with ulceration of the skin, who were not candidate or did not respond to a neo-adjuvant treatment, underwent radical mastectomy and reconstructive surgery. Sixteen patients (59%) were affected by primary tumors of the breast, and eleven patients (41%) had local recurrence after mastectomy or conservative breast surgery. Two main techniques were used for breast reconstruction: transverse rectus-abdominis musculo cutaneous flap in 19 patients (70%), and a fasciocutaneous flap in eight patients (30%). The best procedure in each patient was chosen according to the extent of skin loss or previous radiotherapy to the chest wall. Fourteen patients (52%) died during the follow-up and the median length of survival was 16 months (range 3-79) in transverse rectus-abdominis musculo cutaneous group and 4 months (range 2-23) in fasciocutaneous flap group. The median length of follow-up after treatment for patients still alive was 32.5 months (range 0-96) in transverse rectus-abdominis musculo cutaneous flap group, and 18 months (range 8-41) in fasciocutaneous flap group. At the end of the follow-up, 10 patients were alive without evidence of disease and three patients developed metastatic lesion or local recurrence. The longest recorded disease free interval for a patient still alive and tumor free was 96 months. Only three patients (11%) had local complications: two wound infections and one partial necrosis of the transverse rectus-abdominis musculo cutaneous flap. Median hospital stay was 7 days (range 3-13) for transverse rectus-abdominis musculo cutaneous and 6 days (range 3-13) for fasciocutaneous flap. Our results confirmed that transverse rectus-abdominis musculo cutaneous group and fasciocutaneous flap flaps are good reconstructive options in patients with extended locally advanced breast cancer. Quality of life has improved in this group of patients, with acceptable survival periods and in some cases very important survival rates.
