RESUMEN
BACKGROUND: The purpose of this study was to review and summarize the association between preoperative magnetic resonance imaging (MRI) and surgical outcomes in women with newly diagnosed invasive breast cancer from published randomized controlled trials (RCT). MATERIALS AND METHODS: Two independent researchers conducted a systematic review through a comprehensive search of electronic databases, including PubMed, Medline, Embase, Ovid, Cochrane Library, and Web of Science. If there was disagreement between the two reviewers, a third reviewer assessed the manuscript to determine whether it should be included for data extraction. The quality of the papers was assessed using the risk of bias tool, and the evidence was analyzed using GRADE. Meta-analyses using a fixed-effects model were used to estimate the pooled risk ratio (RR) and 95% confidence interval (CI). RESULTS: Initially, 21 studies were identified, 15 of which were observational comparative studies. A total of five RCTs were included, and they suggested that preoperative MRI significantly reduced the rate of immediate breast-conserving surgery and increased the risk for mastectomy. CONCLUSIONS: From the RCT perspective, preoperative MRI for newly diagnosed invasive breast cancer did not improve surgical outcomes and may increase the risk of mastectomy.
RESUMEN
Introduction: The breasts are a female symbol, impacts self-image and self-esteem. Breast reconstructive and oncoplastic surgeries have an important role in minimizing injuries. In Brazil less than a third of public health system (SUS) users have access to immediate reconstructive surgery. The low rate of breast reconstructions has multiple causes and the deficiency in availability and surgeons' technical qualification play a role. In 2010, the Breast Reconstruction and Oncoplastic Surgery Improvement Course was created by professors of the Mastology Department of Santa Casa de São Paulo and State University of Campinas (UNICAMP). The objectives of this study were to evaluate the impact of the techniques learned on patients' management by the surgeons enrolled in the Course, as well as to characterize their profile. Methods: All students enrolled in the Improvement Course between 2010 and 2018 were invited to answer an online questionnaire. Students who did not agree to answer the questionnaire or answered them incompletely were excluded. Results: Total students included: 59. The mean age: 48.9 years, male (72%) with more than 5 years of Mastology practice (82.2%), from all regions of Brazil, 1.7% from the North, 33.9% from the Northeast, 44.1% from the Southeast, and 12% from the South. Most of the students considered they had little or no knowledge of breast reconstruction (74.6%) and 91,5% did not consider they had enough aptitude to perform breast reconstructions after finishing residency. After the Course, 96.6% considered themselves apt to perform such surgeries. Over 90% of the students considered the Course had impacted their practice and changed their surgical strategy view. Before the Course, 84.8% of the students stated that less than half of their patients who were operated on for breast cancer had breast reconstruction, compared to 30.5% after the Course. Conclusion: The Breast Reconstruction and Oncoplastic Surgery Improvement Course studied here positively impacted the mastologists' management of patients. New training centers worldwide can help a lot of women with breast cancer.
RESUMEN
AIM: Demand for nipple- and skin- sparing mastectomy (NSM/SSM) with immediate breast reconstruction (BR) has increased at the same time as indications for post-mastectomy radiation therapy (PMRT) have broadened. The aim of the Oncoplastic Breast Consortium initiative was to address relevant questions arising with this clinically challenging scenario. METHODS: A large global panel of oncologic, oncoplastic and reconstructive breast surgeons, patient advocates and radiation oncologists developed recommendations for clinical practice in an iterative process based on the principles of Delphi methodology. RESULTS: The panel agreed that surgical technique for NSM/SSM should not be formally modified when PMRT is planned with preference for autologous over implant-based BR due to lower risk of long-term complications and support for immediate and delayed-immediate reconstructive approaches. Nevertheless, it was strongly believed that PMRT is not an absolute contraindication for implant-based or other types of BR, but no specific recommendations regarding implant positioning, use of mesh or timing were made due to absence of high-quality evidence. The panel endorsed use of patient-reported outcomes in clinical practice. It was acknowledged that the shape and size of reconstructed breasts can hinder radiotherapy planning and attention to details of PMRT techniques is important in determining aesthetic outcomes after immediate BR. CONCLUSIONS: The panel endorsed the need for prospective, ideally randomised phase III studies and for surgical and radiation oncology teams to work together for determination of optimal sequencing and techniques for PMRT for each patient in the context of BR.

There are limited data on the effects of anthracyclines on right ventricular (RV) structure, function, and tissue characteristics. The goal of this study was to investigate the effects of anthracyclines on the RV using cardiac magnetic resonance (CMR). This was a post-hoc analysis of a prospective study of 27 breast cancer (BC) patients (51.8 ± 8.9 years) using CMR prior, and up to 3-times after anthracyclines (240 mg/m2) to measure RV volumes and mass, RV extracellular volume (ECV) and cardiomyocyte mass (CM). Before anthracyclines, LVEF (69.4 ± 3.6%) and RVEF (55.6 ± 9%) were normal. The median follow-up after anthracyclines was 399 days (IQR 310-517). The RVEF reached its nadir (46.3 ± 6.8%) after 9-months (P < 0.001). RV mass-index and RV CM decreased to 13 ± 2.8 g/m2 and 8.13 ± 2 g/m2, respectively, at 16-months after anthracyclines. The RV ECV expanded from 0.26 ± 0.07 by 0.14 (53%) to 0.40 ± 0.1 (P < 0.001). The RV ECV expansion correlated with a decrease in RV mass-index (r = -0.46; P < 0.001) and the increase in CK-MB. An RV ESV index at baseline above its median predicted an increased risk of LV dysfunction post-anthracyclines. In BC patients treated with anthracyclines, RV atrophy, systolic dysfunction, and a parallel increase of diffuse interstitial fibrosis indicate a cardiotoxic response on a similar scale as previously seen in the systemic left ventricle.

BACKGROUND: Oncoplastic surgery has been increasingly used in breast cancer treatment and allows the performance of breast-conserving surgery in cases of larger tumors with unfavorable location or tumor-breast disproportion. PURPOSE: To compare surgical and oncological outcomes of patients undergoing oncoplastic and nononcoplastic breast-conserving surgery. METHODS: Retrospective cohort study with convenience sampling of 866 patients who consecutively underwent breast-conserving surgery from 2011 to 2015. RESULTS: The mean follow-up was 50.4 months. Nononcoplastic breast conservation surgery was performed on 768 (88.7%) patients and oncoplastic surgery on 98 (11.3%) patients. Patients in the oncoplastic group were younger (p<0.0001) and most were premenopausal (p<0.0001). Comorbidities such as diabetes (p=0.003) and hypertension (p=0.0001) were less frequent in this population. Invasive carcinoma >2 cm (p<0.0001), multifocality (p=0.004), ductal in situ carcinoma (p=0.0007), clinically positive axilla (p=0.004), and greater weight of surgical specimens (p<0.0001) were more frequent in the oncoplastic group. A second surgery for margin re-excision was more frequently performed in the nononcoplastic group (p=0.027). There was more scar dehiscence in the oncoplastic group (p<0.001), but there was no difference in early major complications (p=0.854), conversion to mastectomy (p=0.92), or local recurrence (p=0.889). CONCLUSION: Although used for the treatment of larger and multifocal tumors, surgical re-excisions were performed less often in the oncoplastic group, and there was no increase in conversion to mastectomy or local recurrence. In spite of the higher rate of overall complications in the oncoplastic group, major complications were similar in both groups.
RESUMEN
PURPOSE: Neoadjuvant endocrine therapy (NET) has been shown to be effective in ER-positive/HER2-negative breast cancer in clinical trials. However, adoption in clinical practice is still limited. Real-world data may provide useful insights into effectiveness, toxicities and quality of care, potentially rendering clinical trial results to the real-world setting. Our purpose was to report real-world data of a cohort of postmenopausal patients submitted to NET. METHODS: This prospective cohort study evaluated 146 postmenopausal female patients with ER-positive/HER2-negative breast cancer treated with NET at three tertiary hospitals between 2016 and 2018. Clinicopathological information were collected prospectively. Preoperative Endocrine Prognostic Index (PEPI) score was calculated for tumors submitted to at least 16 weeks of NET. RESULTS: Median age was 67 years old, and 87.8% had stage I-II disease. Most tumors had histological grade II (76.1%). Median pretreatment Ki67 expression was 10%. Aromatase inhibitor was used in 99.5% of patients, and median treatment duration was 21.0 weeks. No tumor progressed during NET. Breast-conserving surgery was performed in the majority of patients (63.0%), as well as sentinel lymph-node biopsy (76.7%). Pathological complete response rate was 1.0%. 43 patients (29.5%) had PEPI score 0, and 26% had PEPI scores 4-5. Posttreatment Ki67 median expression was 3.0%, and only five tumors (3.4%) showed marked increase in Ki67 expression during treatment. Seven patients (4.8%) had HER2-positive residual disease, and were treated with adjuvant chemotherapy plus trastuzumab. CONCLUSIONS: Our real-world data shows that NET is effective and safe in postmenopausal patients with ER-positive/HER2-negative breast cancer. Postmenopausal status and low-risk luminal tumor features (luminal A-like) should be used as selection criteria to ensure the best results with NET.

PURPOSE: Indications for nipple-sparing mastectomy (NSM) have broadened to include the risk reducing setting and locally advanced tumors, which resulted in a dramatic increase in the use of NSM. The Oncoplastic Breast Consortium consensus conference on NSM and immediate reconstruction was held to address a variety of questions in clinical practice and research based on published evidence and expert panel opinion. METHODS: The panel consisted of 44 breast surgeons from 14 countries across four continents with a background in gynecology, general or reconstructive surgery and a practice dedicated to breast cancer, as well as a patient advocate. Panelists presented evidence summaries relating to each topic for debate during the in-person consensus conference. The iterative process in question development, voting, and wording of the recommendations followed the modified Delphi methodology. RESULTS: Consensus recommendations were reached in 35, majority recommendations in 24, and no recommendations in the remaining 12 questions. The panel acknowledged the need for standardization of various aspects of NSM and immediate reconstruction. It endorsed several oncological contraindications to the preservation of the skin and nipple. Furthermore, it recommended inclusion of patients in prospective registries and routine assessment of patient-reported outcomes. Considerable heterogeneity in breast reconstruction practice became obvious during the conference. CONCLUSIONS: In case of conflicting or missing evidence to guide treatment, the consensus conference revealed substantial disagreement in expert panel opinion, which, among others, supports the need for a randomized trial to evaluate the safest and most efficacious reconstruction techniques.

OBJECTIVES: The goal of this study was to demonstrate that cardiac magnetic resonance could reveal anthracycline-induced early tissue remodeling and its relation to cardiac dysfunction and left ventricular (LV) atrophy. BACKGROUND: Serum biomarkers of cardiac dysfunction, although elevated after chemotherapy, lack specificity for the mechanism of myocardial tissue alterations. METHODS: A total of 27 women with breast cancer (mean age 51.8 ± 8.9 years, mean body mass index 26.9 ± 3.6 kg/m2), underwent cardiac magnetic resonance before and up to 3 times after anthracycline therapy. Cardiac magnetic resonance variables were LV ejection fraction, normalized T2-weighted signal intensity for myocardial edema, extracellular volume (ECV), LV cardiomyocyte mass, intracellular water lifetime (τic; a marker of cardiomyocyte size), and late gadolinium enhancement. RESULTS: At baseline, patients had a relatively low (10-year) Framingham cardiovascular event risk (median 5%), normal LV ejection fractions (mean 69.4 ± 3.6%), and normal LV mass index (51.4 ± 8.0 g/m2), a mean ECV of 0.32 ± 0.038, mean τic of 169 ± 69 ms, and no late gadolinium enhancement. At 351 to 700 days after anthracycline therapy (240 mg/m2), mean LV ejection fraction had declined by 12% to 58 ± 6% (p < 0.001) and mean LV mass index by 19 g/m2 to 36 ± 6 g/m2 (p < 0.001), and mean ECV had increased by 0.037 to 0.36 ± 0.04 (p = 0.004), while mean τic had decreased by 62 ms to 119 ± 54 ms (p = 0.004). Myocardial edema peaked at about 146 to 231 days (p < 0.001). LV mass index was associated with τic (ß = 4.1 ± 1.5 g/m2 per 100-ms increase in τic, p = 0.007) but not with ECV. Cardiac troponin T (mean 4.6 ± 1.4 pg/ml at baseline) increased significantly after anthracycline treatment (p < 0.001). Total LV cardiomyocyte mass, estimated as: (1 - ECV) × LV mass, declined more rapidly after anthracycline therapy, with peak cardiac troponin T >10 pg/ml. There was no evidence for any significant interaction between 10-year cardiovascular event risk and the effect of anthracycline therapy. CONCLUSIONS: A decrease in LV mass after anthracycline therapy may result from cardiomyocyte atrophy, demonstrating that mechanisms other than interstitial fibrosis and edema can raise ECV. The loss of LV cardiomyocyte mass increased with the degree of cardiomyocyte injury, assessed by peak cardiac troponin T after anthracycline treatment.

Objetivo: Apesar do grande número de publicações em cirurgia oncoplástica e reconstrutiva da mama, diversas questões permanecem controversas. Assim, o objetivo desta Reunião de Consenso, foi desenvolver um guia prático de recomendações baseadas nas melhores evidências disponíveis na literatura. Método: Os painelistas foram os membros da Comissão de Cirurgia Oncoplástica e Reconstrutiva da Sociedade Brasileira de Mastologia. A reunião foi realizada em agosto de 2015 em Bento Gonçalves (RS). Cada painelista recebeu e respondeu previamente um questionário com 46 itens, com base na melhor evidencia cientifica e em sua experiência. Foi considerado consenso a concordância de 75% entre painelistas. Resultados: Houve consenso em 25 itens, dos quais para oito houve concordância de 100%. O mais importantes foram: comprometimento das margens em cirurgia oncoplástica pode ser resolvido com ampliação de margens na maioria dos casos; tumores multifocais não são contraindicação para cirurgia oncoplástica; idade >70 anos não representa contraindicação para uso de técnicas oncoplásticas; reconstrução imediata pode ser indicada com segurança para a maioria das candidatas à mastectomia; pacientes com indicação de radioterapia pós-mastectomia podem ser submetidas à reconstrução imediata, devendo ter ciência dos riscos maiores para mau resultado estético; mastectomia com preservação do complexo areolopapilar é segura nos casos de câncer; radioterapia após a mastectomia com preservação do complexo areolopapilar não está indicada fora dos critérios clássicos de irradiação do plastrão; tela abdominal reduz chances de hernia no caso de reconstrução com TRAM. Conclusão: através desta reunião foi possível estabelecer importantes pontos consensuais de acordo com a opinião dos especialistas, que poderão auxiliar os mastologistas na tomada de decisões em cirurgias oncoplásticas e reconstrutivas da mama.
Objective: Despite the large number of publications in oncoplastic and breast reconstructive surgery, several issues remain controversial. The aim of this Consensus Meeting was to develop a practical guide of recommendations based on the best evidence in the literature. Method: All panelists were members of the Oncoplastic Commission of the Brazilian Society of Mastology. The Consensus Meeting was held in Bento Gonçalves (RS), in August 2015. Each panelist received and answered a questionnaire with 46 items, based on the best evidence in the literature and in their expertise. It was considered consensus the agreement of 75% between panelists. Results: There was consensus on 25 items, of which eight were for 100% agreement. The most important of these topics were: involvement of the margins in oncoplastic surgery can be solved by resection of margins in most cases; multifocal tumors is not a contraindication for oncoplastic surgery; age >70 years is not a contraindication for use of oncoplastic techniques; immediate reconstruction can be performed safely to most candidates for mastectomy; patients for post-mastectomy radiotherapy may be subject to immediate reconstruction and should be aware of the risks for poor aesthetic result; mastectomy with preservation of the nipple and areola complex is safe in cancer; radiotherapy after mastectomy with preservation of the nipple and areola complex is not indicated outside the classical criteria of irradiation chest wall; abdominal mash reduces chances of hernia in TRAM flaps. Conclusion: In this meeting it was possible to establish important consensus points according to the opinion of experts, which can help breast surgeons in their decision-making in oncoplastic and reconstructive surgery of the breast.
RESUMEN
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. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, II.

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.

INTRODUCTION: We previously demonstrated that 1 or 5 mg per day of tamoxifen (T) given for four weeks before surgery reduces Ki-67 in breast cancer (BC) patients to the same extent as the standard 20 mg/d. Given the long half-life of T, a weekly dose (10 mg per week (w)) may be worth testing. Also, raloxifene (R) has shown Ki-67 reduction in postmenopausal patients in a preoperative setting, but data in premenopausal women are limited. We conducted a randomized trial testing T 10 mg/w vs. R 60 mg/d vs. placebo in a presurgical model. METHODS: Out of 204 screened subjects, 57 were not eligible, 22 refused to participate and 125 were included in the study. The participants were all premenopausal women with estrogen receptor-positive BC. They were randomly assigned to either T 10mg/w or R 60 mg/d or placebo for six weeks before surgery. The primary endpoint was tissue change of Ki-67. Secondary endpoints were modulation of estrogen and progesterone receptors and several other circulating biomarkers. RESULTS: Ki-67 was not significantly modulated by either treatment. In contrast, both selective estrogen receptor modulators (SERMs) significantly modulated circulating IGF-I/IGFBP-3 ratio, cholesterol, fibrinogen and antithrombin III. Estradiol was increased with both SERMs. Within the tamoxifen arm, CYP2D6 polymorphism analysis showed a higher concentration of N-desTamoxifen, one of the tamoxifen metabolites, in subjects with reduced CYP2D6 activity. Moreover, a reduction of Ki-67 and a marked increase of sex hormone-binding globulin (SHBG) were observed in the active phenotype. CONCLUSIONS: A weekly dose of tamoxifen and a standard dose of raloxifene did not inhibit tumor cell proliferation, measured as Ki-67 expression, in premenopausal BC patients. However, in the tamoxifen arm women with an extensive phenotype for CYP2D6 reached a significant Ki-67 modulation.

OBJECTIVE: We analyzed 382 patients with pure lobular carcinoma treated up to 2002 with sufficient follow-up to draw prognostic conclusions, all treated by conservative surgery. Our aim was to evaluate the influence of margin status on outcomes with a view assessing the appropriateness of conservative surgery in this breast cancer subtype. METHODS: We assessed locoregional relapse, distant metastasis, contralateral breast cancer, breast cancer-related event free survival, disease-free survival and overall survival according to margin status categorized as at least 10 mm versus less than 10 mm (usually considered negative). RESULTS: The proportions of patients with less than 10 mm margins varied significantly with age (P = 0.02), menopausal status (P = 0.006), and tumor size (P = 0.02) but no other characteristic was significantly related to margin status. As regards unfavorable events during follow-up, none differed significantly between at least 10 mm and less than 10 mm margin groups. In particular, there were 11 (3.7%) local relapses in the same quadrant in at least 10 mm margin group compared to 4 (4.6%) in the less than 10 mm margin group, and 7 (2.4%) ipsilateral breast cancers in the 10 mm or more margin group but none in the less than 10 mm group. These findings indicate that minimal residual disease as evidenced by margins less than 10 mm is eradicated by radiotherapy (backed up in selected cases by reexcision, which in this series was always conservative). The rate of contralateral breast cancer was low at 2.9% indicating that prophylactic contralateral mastectomy is not justified. CONCLUSIONS: We conclude that the surgical approach and criteria for adjuvant hormonal and systemic treatment in lobular carcinoma should be the same as for ductal carcinoma, provided that adequate preoperative investigations exclude extensive multifocal and contralateral disease.

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.

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.

BACKGROUND: Although invasive lobular carcinoma (ILC) is the second most common histotype of breast cancer, the prognostic implications of its clinicopathologic characteristics remain controversial. METHODS: The authors undertook a retrospective analysis of a large series of cases treated and followed at a single institution, with the objective of assessing the prognostic/predictive value of distinct clinicopathologic features of the tumors, after revision of the original histopathologic preparations and statistical analyses. RESULTS: Overall, 530 patients with pure ILC (57% with the classic type; 19% with the alveolar type; 11% with the solid type; and the remaining 13% characterized by pleomorphic, signet ring cell, histiocytoid, or apocrine features) were included in the study. Tumor size, lymph node metastatic involvement, and hormonal status were confirmed to be significant prognostic factors. In addition, statistically significant correlations were demonstrated between the 'classic' histotype of ILC and a lower risk of axillary lymph node metastases (P = .0005), a reduced number of metastatic lymph nodes (P = .04), and lower tumor grade (P < .0001). Patients with ILC of the 'nonclassic' subtype demonstrated significantly increased breast-related events (hazards ratio of 1.80; 95% confidence interval, 1.04-3.10) and a trend toward reduced disease-free survival and overall survival. CONCLUSIONS: The results of the current study confirm the clinical usefulness of several traditional clinicopathologic features of ILC as prognostic parameters but also emphasize the prognostic role of the histopathologic subtyping of these tumors, documenting the more favorable outcome of the classic subtype of ILC.

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.
