Abstract
Breast cancer is a common cancer among women. The transverse rectus abdominis myocutaneous (TRAM) flap is a popular option because not only does it provide a breast with satisfactory bulk composed of autogenous tissue but it also provides an abdominal dermolipectomy to the patient. Fat necrosis remains a common problem following TRAM flap reconstruction, occurring in 10% to 36% of patients undergoing the procedure. A 44-year-old woman underwent a modified radical mastectomy followed by pedicled TRAM flap reconstruction after 5 months. Follow-up mammography 27 months after TRAM flap reconstruction showed a cluster of microcalcifications in the deep retroareolar area and recurrent breast carcinoma was highly suspected. Physical examination did not detect any abnormality of the reconstructed breast. Stereotactic hook localization was performed and an excisional biopsy was successfully done. The histological features of the resected specimens corresponded to fat necrosis change. Only with the awareness of the existence of such entity and careful follow-up can the occurrence of fat necrosis in TRAM flap reconstructed breasts be accurately detected and appropriately treated.

Recurrence after skin-sparing mastectomy and immediate transverse rectus abdominis musculocutaneous flap reconstruction for invasive breast cancer. World J Surg Oncol 2013; 11:194. [PMID: 23945398 PMCID: PMC3751148 DOI: 10.1186/1477-7819-11-194] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2013] [Accepted: 08/05/2013] [Indexed: 11/28/2022] Open
Abstract
Background The aim of this study was to evaluate the recurrence pattern after skin-sparing mastectomy (SSM) and immediate breast reconstruction (IBR) using transverse rectus abdominis musculocutaneous (TRAM) flap in patients with invasive breast cancer. Methods From 1995 to 2010, patients with invasive breast cancer who underwent SSM followed by IBR using TRAM flap were retrospectively reviewed. The pattern of the first recurrence event was recorded. Results We identified 249 consecutive patients with invasive breast cancer, two-thirds of whom (67.1%) were diagnosed with stage II or stage III disease. During a median follow-up period of 53 months, three (1.2%) local, 13 (5.2%) regional, 34 (13.7%) distant, and five (2.0%) concurrent locoregional and distant recurrences were observed. The median time to recurrences was 26 months (range, 2 to 70 months) for all recurrences, 23 months (range, 2 to 64 months) for locoregional recurrences, and 26 months (range, 8 to 70 months) for distant recurrences. All local recurrent lesions were detectable by careful physical examination, and detection of local recurrence suggested the presence of distant metastasis (60.0%). In contrast to distant metastasis, the risk of locoregional recurrence did not increase significantly with an increase in disease stage. The 5-year overall, locoregional relapse-free, and distant relapse-free survival rates were 89.7%, 90.8%, and 81.6%, respectively. Conclusions SSM followed by immediate reconstruction using TRAM flap is an oncologically safe procedure even in patients with advanced-stage disease. Detection of local recurrence is crucial and can be aided by a thorough physical examination.

Abstract
BACKGROUND The locoregional recurrence (LRR) rate after mastectomy is reported to be similar with immediate reconstruction. We aimed to identify characteristics of LRR after transverse rectus abdominis myocutaneous (TRAM) reconstruction. METHODS We retrospectively reviewed patients undergoing immediate TRAM reconstruction for breast cancer who were diagnosed with LRR. RESULTS We identified 18 LRR (4.6 %) in 18 of 390 patients who underwent immediate TRAM reconstructions for breast cancer from 1998 to 2008. The median follow-up was 69.2 months. The mean age at time of mastectomy was 49.5 years. All LRR were detected by physical examination. The LRR occurred in the TRAM subcutaneous tissue (n = 9), five in the ipsilateral axillary lymph node and four in the supraclavicular lymph node. Of the 18 patients who developed LRR, 14 (77.7 %) presented with stage 0-1-2 and 4 (22.2 %) with stage 3 disease at the time of the original mastectomy. The average time for a LRR to present was 35.8 months after initial mastectomy and reconstruction. For patients who initially presented with stage 3 disease, the average time to LRR was shorter (22.9 months). Nine patients (50.0 %) were found to have metastatic disease at the time of the LRR, and 6 (33.3 %) died of disease. CONCLUSIONS All TRAM LRR were detected by routine physical examination by the patient or the surgeon. Our findings suggest that routine history and clinical breast examination of the breast reconstructed with a TRAM flap along with patient self-awareness are reliable in the diagnosis of LRR.

Abstract
Despite developments in surgical technique, radiation treatment, and chemotherapeutic agents, tumor recurrence and distant disease have remained a major concern in breast cancer management. Breast imaging after mastectomy in the screening arena remains a controversial topic for breast imagers. Many feel the yield of finding a recurrent cancer with imaging in the asymptomatic patient is too low to be beneficial; others believe imaging should be performed on these patients as the risk of recurrence exists. Patients after a mastectomy procedure are considered high risk and, when they present with clinical symptoms, will require evaluation by the radiologist. In this diagnostic/symptomatic scenario, imaging becomes the routine and current imaging tools, such as mammography, ultrasound, and magnetic resonance imaging (MRI), can easily be incorporated to diagnose recurrent cancer. Our facility has a large population of patients that undergo mastectomy after a carcinoma diagnosis as well as a number of patients that have undergone a mastectomy procedure because of their high-risk status (whether family history or genetic predisposition). A certain percentage of these patients have proceeded to reconstructive surgery. We image these patients routinely as part of our screening protocol. Over the years we have become familiar with the appearance of remaining tissue along the chest wall after mastectomy as well as the reconstructed breasts. This familiarity is important as the imaging of these patients with mammography and other modalities available today can be challenging. This manuscript will discuss the benefits and some limitations surrounding imaging these patients, in both the asymptomatic and symptomatic scenarios, as well as what imaging protocols can be integrated within a facility's standard evaluation.

Abstract
Locoregional breast cancer recurrence is a relatively rare event, occurring more frequently in patients diagnosed with more advanced stages of cancer and those with inflammatory features. While typical signs of recurrence after reconstruction include the development of a mass in the native skin or deep chest wall, oncologic relapse may also rarely be heralded by subtle cutaneous changes. This article describes a patient with inflammatory breast cancer who underwent neoadjuvant chemotherapy, mastectomy, radiation therapy, and hormonal therapy followed by delayed reconstruction with a deep inferior epigastric artery perforator flap and subsequently presented with a recurrence manifest as a localized rash over the upper abdomen. Surgeons who perform breast reconstruction should be attuned to both common and uncommon recurrence symptoms, as they may be the first to diagnose recrudescent disease.

Abstract
BACKGROUND Peri-ductal mastitis is an uncommon benign disorder of the major lactiferous ductal system of the female breast. It can be a very difficult problem to treat and may cause significant patient morbidity. We describe a new technique, involving use of the pectoralis major muscle flap, for treating recurrent sub-areolar abscess refractory to standard surgical treatment. METHOD Three patients who underwent this new technique for severe refractory peri-ductal mastitis at Calvary Hospital, Canberra are presented. RESULTS These patients who had recurrent peri-ductal mastitis with abscess and fistula formation on a monthly basis despite numerous courses of antibiotics and surgical procedures experienced no further recurrences following pectoralis major interposition flap surgery at 42, 32 and 22 months follow-up respectively. CONCLUSION This new technique may provide an opportunity to control these otherwise difficult to treat cases of severe recurrent peri-ductal mastitis where standard surgical methods have failed.

Abstract
PURPOSE Mastectomies result in very high local control rates for pure ductal carcinoma in situ; however, close or involved tumor margins are occasionally encountered. Data regarding the patterns of relapse in this setting are limited. METHODS AND MATERIALS Between 1994 and 2002, the pathology reports of 574 patients who had undergone mastectomy at our institution for pure ductal carcinoma in situ were retrospectively reviewed. Of the 574 patients, 84 were found to have margins of <10 mm. Of the 84 patients, 4 underwent postoperative radiotherapy and were excluded, leaving 80 patients for this analysis. Of the 80 patients, 31 had margins <2 mm and 49 had margins of 2.1-10 mm. High-grade disease was observed in 47 patients; 45 patients had comedonecrosis; and 30 had multifocal disease. Of the 80 patients, 51 were <60 years of age. RESULTS With a median follow-up of 61 months, 6 (7.5%) of the 80 patients developed local recurrence. Of the 31 patients with a margin of <or=2 mm, 5 (16%) developed local recurrence vs. only 1 (2%) of 49 patients with a margin of 2.1-10 mm (p = 0.0356). Of the 6 patients with local recurrence, 5 had high-grade disease and/or comedonecrosis. All six recurrences were noted in patients <60 years old. CONCLUSION The findings of this review suggest that patients with pure ductal carcinoma in situ who undergo mastectomy with a margin of <2 mm have a greater-than-expected incidence of local recurrence. Patients with additional unfavorable features such as high-grade disease, comedonecrosis, and age <60 years are particularly at risk of local recurrence. These patients might benefit from postmastectomy radiotherapy.

Abstract
BACKGROUND Both the prevalence of breast cancer and the number of breast cancer patients seeking breast reconstruction are increasing, highlighting the importance for evidence to direct the clinician in the follow-up of these patients. Current practice guidelines recommend surveillance mammography of the contralateral breast in all breast cancer patients, and of the ipsilateral breast in women treated with breast-conserving surgery. However, there are no guidelines specifically addressing the role of surveillance mammography for women who have undergone mastectomy and breast reconstruction. METHODS A systematic review was conducted to identify studies specifically addressing the issue of surveillance mammography among women with breast reconstruction following treatment for primary breast cancer. RESULTS This systematic review identified eight articles, consisting of case reports and case series, that address the issue of surveillance mammography of the ipsilateral breast in women with breast reconstruction. The articles demonstrated that certain local recurrences are able to be detected by surveillance mammography. CONCLUSION This study has demonstrated the paucity of evidence and highlighted the need for further research to evaluate this issue.

Abstract
BACKGROUND The transverse rectus abdominis musculocutaneous (TRAM) flap is the standard in autologous breast reconstruction. The management of local recurrence of breast cancer after TRAM flap breast reconstruction has not been well described. The purpose of this study was to examine the incidence of local recurrence of breast cancer after TRAM flap breast reconstruction, evaluate treatment modalities, and determine outcomes in such cases. METHODS A retrospective review was conducted of all patients who underwent immediate breast reconstruction with a free or pedicled TRAM flap over a 15-year period. Those patients who experienced local breast cancer recurrence were identified. A subset of complete skin-sparing mastectomy patients was also identified for review. RESULTS From 1987 to 2002, 419 TRAM flap breast reconstructions were performed in 395 patients. Thirty-four (9 percent) were complete skin-sparing mastectomy using a periareolar mastectomy incision only. The mean follow-up time in this study was 4.9 years (range, 1 to 14.7 years). Local recurrence occurred in 16 of 419 patients (3.8 percent), with a mean time to local recurrence of 1.6 years (range, 0.2 to 7.0 years). There were no local recurrences seen in patients following complete skin-sparing mastectomy. Treatment of local recurrence included excision, chemotherapy, radiotherapy, and bone marrow transplant. Only three of the 16 patients (19 percent) required removal of the entire TRAM flap to manage local breast cancer recurrence. Nine of 16 patients (56 percent) with local recurrence died of disease at a mean of 1.2 years after the development of recurrence. CONCLUSION Long-term follow-up demonstrated a local recurrence rate after TRAM flap breast reconstruction similar to that reported in the literature. Local recurrence was effectively managed with surgical excision of the involved tissues, chemotherapy, and/or radiation therapy. Removal of the entire TRAM flap was only necessary in the setting of multifocal recurrence or involvement of the flap pedicle with disease. The risk of local recurrence was not increased following complete skin-sparing mastectomy.

Abstract
A reconstrução mamária com retalho miocutâneo tem sido amplamente utilizada em pacientes submetidas a mastectomia radical modificada por câncer de mama, com melhora significativa na auto-estima dessas pacientes, minimizando o sentimento de mutilação e melhorando a estética, sem promover alteração no prognóstico da doença. Inicialmente acreditava-se não haver risco de recorrência do câncer na mama reconstruída devido à remoção completa do tecido mamário. Porém, exames histológicos têm demonstrado que pode restar pequena quantidade de tecido mamário local após a mastectomia, tendo este tecido remanescente alto potencial de malignidade. Tem-se preconizado o acompanhamento clínico dessas pacientes, uma vez que a maioria das lesões recidivantes se situa nos pontos de inserção do retalho e elas são passíveis de serem detectadas pela palpação. No entanto, tem-se discutido a inclusão da mamografia e da ultra-sonografia no controle dessas pacientes, uma vez que estes métodos podem contribuir para o diagnóstico de lesão recorrente antes de esta tornar-se palpável.

Abstract
We have been using the lipomodeling technique since 1999 in order to improve the form and the volume of the breasts reconstructed with latissimus dorsi flap. During several recent years this technique has known a considerable development and its results are quite attractive. At the same time, the breast imaging remains to be a fundamental mean of cancer control. The knowledge of radiological manifestations of the implanted fat tissue is very important. The aim of this study was to evaluate the imaging aspects of lipomodeling in breasts reconstructed with latissimus dorsi flap, using three types of explorations: ultrasound, radiological mammography and MRI. A total of 30 patients were included into the study with average age of 51 years. All of these patients underwent a breast reconstruction using a latissimus dorsi flap with lipomodeling, which average volume reached 165 cc. Four of the patient had a bilateral breast reconstruction. Three modes of imaging (ultrasound, mammography and MRI) were performed a year after the surgery. In 20 patients the imaging findings proved to be normal (in total 34 breasts). An image of fat tissue was revealed in 14 cases and some benign microcalcifications were found in 4 patients. A suspicious tissular image was discovered in one patient, who later underwent a biopsy. The result was a benign giant cell granuloma. In conclusion, the lipomodeling technique does not affect the postoperative follow-up of the patients with breast cancer and an imaging controlled biopsy is possible in case of any doubt. At present, some additional studies are underway evaluating the fat tissue transplants in normal breasts, in order to widen its indications in the plastic breast surgery.

Abstract
Abstract
Reconstruction after mastectomy for breast carcinoma with implants or myocutaneous flaps is a widely used surgical technique. Recurrence of breast carcinoma after these procedures is uncommon. Most recurrences occur in the skin or scar site of the mastectomy and are readily detectable by physical examination. There are rare reported cases of recurrent carcinoma occurring within the flaps that are usually diagnosed with the aid of imaging and subsequent pathologic examination. In most cases, these recurrences represent invasive or in situ ductal carcinoma. We report an additional 2 cases of breast carcinoma recurring within the myocutaneous flap, both of which exhibited uncommon histologic features not previously reported.

Abstract
The authors retrospectively reviewed their clinical database for cases of breast magnetic resonance (MR) imaging performed in women who had undergone breast reconstruction with a transverse rectus abdominis myocutaneous (TRAM) flap. Patient histories, MR imaging results, and, when available, biopsy results were reviewed. During a 4-year period, 24 neobreasts were imaged in 22 women who had undergone TRAM flap reconstruction after mastectomy. In most of the cases (64%), the indication for MR imaging was a palpable abnormality or pain. In four of 24 cases (17%), recurrent breast cancer was detected. These cases consisted of a local chest wall tumor (n = 2), an infiltrating chest wall tumor (n = 1), and axillary nodal recurrence (n = 1). In all four cases, MR imaging demonstrated a suspicious lesion or abnormality. In 11 of 24 cases (46%), benign findings only were demonstrated. These consisted of localized or diffuse skin thickening, fibrosis, fat necrosis, and seroma. In nine of 24 cases (38%), no pathologic abnormality was identified. MR imaging is useful in detection of locally recurrent tumor in patients who have undergone breast reconstruction with a TRAM flap. MR imaging allows differentiation between benign and malignant findings in patients with palpable abnormalities or pain after TRAM flap reconstruction.

Abstract
The last several decades have witnessed significant advances in the surgical management of breast cancer. Although many have embraced breast conservation as the procedure of choice, some patients will still opt for mastectomy for a variety of reasons. Recently, the concept of skin sparing mastectomy and immediate breast reconstruction has emerged as an option that provides excellent cosmetic results while being oncologically safe. However, this surgical approach must be considered within a multidisciplinary context, and there are a number of perioperative issues that need to be considered. In addition, newer techniques, which spare the nipple and/or areola, warrant further examination.

Abstract
OBJECTIVE To present mammographic and ultrasonographic findings in various types of reconstruction using an autogenous myocutaneous flap after mastectomy or breast-conserving surgery. METHODS Mammography and ultrasonography performed in patients who had undergone reconstruction mammoplasty using the autogenous myocutaneous flap procedure were reviewed to facilitate recognition of both normal and abnormal postoperative appearances of the various types of reconstruction using the autogenous myocutaneous flap after mastectomy or breast-conserving surgery. RESULTS Normal mammographic and ultrasonographic findings include predominance of a fatty appearance, surgical clips, and surgical scars. Abnormal mammographic and ultrasonographic findings include fat necrosis, calcifications, and locally recurrent carcinoma. Ultrasonographic findings of fat necrosis were cystic, complex, and solid-appearing masses with circumscribed or poorly defined margins in peripheral portions of the flap. Ultrasonographic findings of locally recurrent carcinoma were poorly defined heterogeneous hypoechoic lesions in reconstructed breast, similar to those of primary breast cancer. CONCLUSIONS Breast reconstruction using the autogenous myocutaneous flap has increased in popularity with various methods. Mammography and ultrasonography facilitated excellent visualization of normal and abnormal findings of various reconstructed breasts with the autogenous myocutaneous flap.

Abstract
BACKGROUND Chest wall recurrence (CWR) in the setting of previous mastectomy and breast reconstruction can pose complex management dilemmas for clinicians. We examined the impact of breast reconstruction on the treatment and outcomes of patients who subsequently developed a CWR. METHODS Between 1988 and 1998, 155 breast cancer patients with CWR after mastectomy were evaluated at our center. Of these patients, 27 had previously undergone breast reconstruction (immediate in 20; delayed in 7). Clinicopathologic features, treatment decisions, and outcomes were compared between the patients with and without previous breast reconstruction. Nonparametric statistics were used to analyse the data. RESULTS There were no significant differences between the reconstruction and no-reconstruction groups in time to CWR, size of the CWR, number of nodules, ulceration, erythema, and association of CWR with nodal metastases. In patients with previous breast reconstruction, surgical resection of the CWR and repair of the resulting defect tended to be more complex and was more likely to require chest wall reconstruction by the plastic surgery team rather than simple excision or resection with primary closure (26% [7 of 27] versus 8% [10 of 128], P = 0.013). Risk of a second CWR, risk of distant metastases, median overall survival after CWR, and distant-metastasis-free survival after CWR did not differ significantly between patients with and without previous breast reconstruction. CONCLUSIONS Breast reconstruction after mastectomy does not influence the clinical presentation or prognosis of women who subsequently develop a CWR. Collaboration with a plastic surgery team may be beneficial in the surgical management of these patients.

Abstract
PURPOSE To assess the value of ultrasonography (US) and US-guided fine-needle aspiration biopsy (FNAB) in the detection and diagnosis of recurrent cancer in breasts reconstructed with autogenous myocutaneous flaps after mastectomy for primary breast cancer and to describe the US appearances of recurrence in the reconstructed breast. MATERIALS AND METHODS Between July 1994 and March 2001, US of the reconstructed breast was performed in 20 women with autogenous myocutaneous flap reconstruction. US findings were correlated with clinical and mammographic findings. US-guided FNAB of 25 (64%) of the 39 recurrent cancers depicted at US was performed. RESULTS Twenty-one (54%) of the 39 recurrent cancers depicted at US were clinically occult. Mammography performed in 12 of the 20 patients with reconstructed breasts depicted 14 (56%) of the 25 recurrent cancers that were detected at US in these patients. US-guided FNAB helped to establish a definitive diagnosis of recurrent breast carcinoma in 24 (96%) of the 25 tumor specimens sampled. CONCLUSION US and US-guided FNAB are valuable for the assessment of both palpable and clinically occult recurrent breast cancers in autogenous myocutaneous flap breast reconstructions.

Abstract
Local recurrence of cancer after mastectomy and immediate breast reconstruction is generally regarded as a poor prognostic indicator. This study was conducted to identify specific patterns of local recurrence following reconstruction and to determine their biological significance. The records of all patients who had undergone immediate breast reconstruction at The University of Texas M. D. Anderson Cancer Center between June 1, 1988, and December 31, 1998, were reviewed. The records of patients who had local tumor recurrence were then carefully analyzed. During this 10-year period, a local recurrence of cancer was found to have developed in 39 of 1694 patients (2.3 percent). Most recurrences were in the skin or subcutaneous tissue (n = 28; 72 percent), and the remainder were in the "chest wall" (n = 11; 28 percent), as defined by skeletal or muscular involvement. Transverse rectus abdominis myocutaneous flaps were used most often in both groups, but latissimus dorsi myocutaneous flaps and implant techniques were also used in some patients. Patients with subcutaneous tissue recurrence had an overall survival rate of 61 percent at follow-up of 80.8 months, compared with patients with chest wall recurrence, whose survival rate was 45 percent at similar follow-up. Metastases were less likely to develop in patients with subcutaneous tissue recurrence than in those with chest wall recurrence (57 percent versus 91 percent; p = 0.044); the former group also had a greater chance of remaining disease-free after treatment of the recurrence (39 percent versus 9 percent), respectively. Metastasis-free survival was higher in patients with subcutaneous tissue recurrence than with chest wall recurrence (2-year and 5-year survival: 52 and 42 percent versus 24 and 24 percent; p = 0.04). In both groups, the time to detection of the recurrence was similar (subcutaneous tissue recurrence, 27.1 months, versus chest wall recurrence, 29.5 months). Distant disease did not develop in one patient only in the chest wall recurrence group; this patient remained disease-free at 70 months. From these results, it was concluded that (1) not all local recurrences are the same: patients with subcutaneous tissue recurrence have better survival rates, a decreased incidence of metastases, and a greater chance of remaining disease-free than do those with chest wall recurrence; (2) immediate breast reconstruction (although potentially, it can conceal chest wall recurrence) does not seem to delay the detection of chest wall recurrence; and (3) even if a chest wall recurrence develops, it is highly associated with metastatic disease, and the survival rate is not likely to have been influenced by earlier detection. These data support the continued use of immediate breast reconstruction without fear of concealing a recurrence or influencing the oncologic outcome.

Abstract
Inflammatory breast cancer (IBC) is the most lethal form of locally advanced breast cancer known. IBC carries a guarded prognosis primarily due to rapid onset of disease, typically within six months, and the propensity of tumor emboli to invade the dermal lymphatics and spread systemically. Although the clinical manifestations of IBC have been well documented, until recently little was known about the genetic mechanisms underlying the disease. In a comprehensive study aimed at identifying the molecular mechanisms responsible for the unique IBC phenotype, our laboratory identified overexpression of RhoC GTPase in over 90% of IBC tumors in contrast to 36% of stage-matched non-IBC tumors. We also demonstrated that overexpression of RhoC GTPase in human mammary epithelial (HME) cells nearly recapitulated the IBC phenotype with regards to invasion, motility and angiogenesis. In the current study we sought to delineate which signaling pathways were responsible for each aspect of the IBC phenotype. Using well-established inhibitors to the mitogen activated protein kinase (MAPK) and phosphatidylinositol-3 kinase (PI3K) pathways. We found that activation of the MAPK pathway was responsible for motility, invasion and production of angiogenic factors. In contrast, growth under anchorage independent conditions was dependent on the PI3K pathway.

Abstract
PURPOSE To evaluate findings from routine mammographic screenings in patients with transverse rectus abdominis musculocutaneous (TRAM) flap reconstructions. MATERIALS AND METHODS During a 25-month study period, 214 consecutive screening mammograms in 113 asymptomatic women (mean age, 51 years) with TRAM flap reconstructions were obtained. Mastectomies were performed for cancer in 106 (94%) of the 113 women and for prophylaxis in seven (6%). Prospectively, a Breast Imaging Reporting and Data System (BI-RADS) assessment category 1-5 was assigned to each mammogram. Surgical, medical, pathologic, and radiographic records were retrospectively reviewed. CIs were determined by the normal approximation to the binomial distribution. RESULTS Seven (3%) of 214 examinations were BI-RADS category 4 or 5. Six (86%) of seven patients underwent biopsy. Two (33%) of these six biopsies demonstrated invasive ductal carcinoma. Cancer detection rate for mammography was 1.9% (two of 106) (95% CI: 0.33%, 7.32%) for women with reconstruction for breast cancer during the 2-year period. One (6%) of 16 BI-RADS category 3 examinations later proved to be invasive ductal carcinoma at follow-up. No interval cancer was discovered in 171 cases of BI-RADS category 1 or 2 examinations with 1-year follow-up. No cancers occurred in women who underwent prophylactic mastectomy. A biopsy positive predictive value of 33% (95% CI: 6%, 76%) was observed. CONCLUSION Screening mammography of TRAM flap-reconstructed breasts enables detection of nonpalpable cancer before clinical examination.

Abstract
PURPOSE Patients younger than 35 to 45 years old at the time of diagnosis of invasive breast cancer have been found to have a worse prognosis than older patients in many studies. However, the impact of patient age at diagnosis on the outcome of treatment with either lumpectomy and radiation therapy (RT) or mastectomy for patients with ductal carcinoma-in-situ (DCIS) of the breast has not been extensively analyzed. MATERIALS AND METHODS Articles addressing the effect of patient age at diagnosis on the outcome of treatment of DCIS with lumpectomy and RT or mastectomy were identified through the MEDLINE and CancerLit databases and reference lists of relevant articles. Studies were reviewed to determine the impact of patient age at diagnosis on clinical and pathologic features of DCIS, the influence of age on outcome after lumpectomy and RT, and the impact of age on outcome after mastectomy. RESULTS DCIS in younger patients more frequently contains adverse prognostic pathologic factors and extends over a greater distance in the breast than in older patients. In series with adequate follow-up, younger patients treated with lumpectomy and RT had a significantly higher rate of local recurrence than older patients, especially for invasive local recurrences. Some studies have suggested that careful attention to margin status and excising larger volumes of tissue can reduce this difference substantially. No available data show that younger patients have better long-term cancer-free survival rates if treated by mastectomy rather than lumpectomy and RT. CONCLUSION Successful treatment of younger patients with DCIS with lumpectomy and RT requires careful attention to patient evaluation, selection, and surgical technique. When this is done, age at diagnosis should not be a contraindication to breast-conserving therapy.

Abstract
Breast cancer remains a significant cause of morbidity and mortality among women today. The transverse rectus abdominis myocutaneous (TRAM) flap has played a substantial role in the reconstruction of defects secondary to mastectomy. Although such reconstruction has not been shown to adversely affect survival or local recurrence, specific screening modalities for recurrence in this population of patients have not been delineated. Three patients were examined retrospectively at the authors' institution. They presented with local recurrences of breast cancer after mastectomy and TRAM flap reconstruction. All patients' recurrences were detected on physical examination, and all had the diagnosis of recurrent carcinoma made on biopsy of the mass. A review of the literature demonstrates that mammography, ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), scintimammography, and biopsy have all been used as adjuncts to clinical examination in detecting recurrence. Subsequent treatment of recurrent breast cancer is determined by the results of a metastatic workup and the receptor status of the tumor. The most reliable form of diagnosis of recurrent breast cancer after TRAM flap reconstruction remains fine-needle, core, or open biopsy if indicated.

Abstract
In the transverse rectus abdominis musculocutaneous (TRAM) flap procedure, a portion of the abdominal wall is transposed to the chest as a pedicle or free flap. Patients who have undergone this procedure often subsequently undergo computed tomography (CT) for assessment of metastatic disease or unrelated pathologic conditions. CT scans obtained in patients who had undergone the TRAM flap procedure were reviewed to facilitate recognition of both the normal and abnormal postoperative CT appearances of the TRAM flap. In 28 reconstructed breasts in 21 patients, three general appearances were identified: type 1 (homogeneous fat attenuation) (n = 4), type 2 (fat attenuation with a thin, curvilinear soft-tissue band parallel to the skin surface) (n = 19), and type 3 (thick soft-tissue band parallel to the skin surface) (n = 5). A mass that arose in a type 2 breast 21 months after surgery represented recurrent cancer. A markedly thickened soft-tissue band in another patient represented a dry eschar with inflammation and fat necrosis. The rectus abdominis muscle was partially absent in eight cases and completely absent in 20 cases. Recognition of the normal postoperative appearance of the body wall helps avoid confusion with disease states and allows identification of abnormal conditions such as inflammation, infection, and recurrent breast cancer.

Abstract
Autologous myocutaneous flaps (AMFs) are used increasingly as a method of breast reconstruction after mastectomy for breast cancer. Autogenous breast reconstruction may be performed with a rectus abdominis, latissimus dorsi, or gluteus maximus myocutaneous flap. Mammographic imaging of AMFs is controversial but has been recommended by some authors because mammographic detection of nonpalpable local recurrences in AMFs continues to be reported. At mammography, AMFs have a predominantly fatty appearance with variable density due to the muscle component and postoperative scarring. Normal mammographic findings include the vascular pedicle, surgical clips, and surgical scars, which produce radiopaque lines in predictable locations. Abnormal mammographic findings include fat necrosis appearing as a spiculated mass, noncalcified or calcified lipid cysts, calcifications, lymph nodes, epidermal inclusion cysts, and locally recurrent carcinoma.
