Oncological Safety of Oncoplastic Level II Mammoplasties After Neoadjuvant Chemotherapy for Large Breast Cancers: A Matched-Cohort Analysis.

BACKGROUND: Oncoplastic surgery (OPS) has extended the indications for breast-conserving surgery (BCS). Its role in patients with large breast cancers treated with neoadjuvant chemotherapy (NAC) is unclear. This study evaluated the oncological safety of OPS for tumors with partial response after NAC. METHODS: A consecutive series of 65 patients who underwent OPS (study group) after NAC for large breast cancer from January 2004 to July 2018 was compared with 130 matched patients treated by NAC, followed by standard BCS in 65 cases and mastectomy in 65 cases (two case-controlled groups). RESULTS: The mean initial radiological tumor size was 46 mm. Residual pathological tumor size was 22 mm in the OPS cohort, 19 mm in the standard BCS cohort, and 31 mm in the mastectomy cohort (p > 0.05). The mean follow-up was 59 months in the study cohort. Five-year local recurrence rates were 0%, 0%, and 10.5% (0-22%) for the OPS, BCS, and mastectomy cohorts, respectively, while 5-year regional recurrence rates were 4.1% (0-11.1%), 0, and 19.4% (0-35.2%, p > 0.05), respectively. Five-year overall survival was 85.3% for the OPS cohort, 94.1% for the standard BCS cohort (p = 0.194), and 79.9% for the mastectomy cohort (p = 0.165). CONCLUSIONS: OPS is safe after NAC for large breast cancers, and provides excellent local control, identical to that of tumors with a better response, treated by standard BCS. After NAC, OPS can be a valuable treatment option for tumors that did not shrink optimally and would not be suitable for standard BCS.

Does a pre-operative conization improve disease-free survival in early-stage cervical cancer?

PURPOSE: Ever since the recent findings showing the lack of benefit of minimally invasive surgery (MIS) versus open surgery in early-stage cervical cancer, gynecologists have tried to explain these results. The primary objective of our study was to assess the impact of pre-operative conization on disease-free survival (DFS) in early-stage cervical cancer. The secondary objective was to analyze the peri-operative morbidity associated with a pre-operative conization. METHODS: All patients undergoing a surgical management for early-stage squamous carcinoma or adenocarcinoma cervical cancer (IA1, IA2, IB1 and IB2 FIGO 2018) at a French university hospital from 2004 to 2018 were retrospectively included. We examined the association between conization and DFS using a Cox regression model. We also analyzed the morbidity associated with pre-operative conization. RESULTS: 48.4% (44/91) of the patients had a pre-operative conization (defined by a conization up to 90 days prior to surgery). 86.8% underwent MIS. There was a non-significant increase in the DFS with one patient presenting a recurrence in the conization group (2.3%) and six (12.8%) in the no conization group (log rank = 0.09). In univariate analysis, conization, definitive FIGO stage and pre-operative tumor size were associated with DFS (p < 0.2). Only pre-operative tumor size was significantly associated with DFS in multivariate analysis. There was a non-significant increase of adverse events in the conization group (43.2% in the conization group versus 23.4%, p = 0.06). CONCLUSION: Conization, through a reduction of tumor size, could improve DFS. Carefully selected patients could still benefit from minimally invasive surgery.

[Hereditary breast and ovarian cancer syndrome: Diagnosis and therapeutic implications]. / Syndrome héréditaire de prédisposition au cancer du sein et de l'ovaire : diagnostic et implications thérapeutiques.

Patients who carry the BReast Cancer 1 or 2 (BRCA) gene mutations have an underlying hereditary predisposition for breast and ovarian cancers. These deleterious genetic mutations are the most common ones implicated in hereditary breast and ovarian cancers. Oncogenetic counselling plays a key role in identifying patient for BRCA testing and for mutation identification. BRCA1/2 carriers have to be followed up regularly and may justify breast and/or adnexal prophylactic surgery, according to the French National Cancer Institute guidelines (INCa). Poly- (DNA-riboses) polymerases inhibitors, notably olaparib, have a major role in the management of epithelial ovarian cancer in patients with BRCA mutation and many studies are ongoing to expand their indications in a near future.

Long-term Results After Oncoplastic Surgery for Breast Cancer: A 10-year Follow-up.

OBJECTIVE: The aim of this study was to evaluate the long-term oncologic outcome after oncoplastic surgery (OPS). BACKGROUND: OPS combines wide tumor excision with reduction mammoplasty techniques thus extending breast conserving surgery to large tumors that might else be proposed a mastectomy. Little data are available about the oncologic results for breast conserving surgery of these larger tumors. METHODS: From January 2004 until March 2016, a total of 350 oncoplastic breast reductions were prospectively entered into a database. Patients were included if their breast reshaping included a reduction mammoplasty with skin excision (Level 2 oncoplastic techniques). RESULTS: Histologic subtypes were: invasive ductal carcinoma in 219 cases (62.6%), ductal carcinoma in situ (DCIS) in 88 cases (25.1%), and invasive lobular carcinoma in 43 (12.3%) cases. Seventy-three of the invasive cancers (27.9%) received neoadjuvant chemotherapy. The mean resection weight was 177 grams. The mean pathological tumor size was 26 mm (range 0-180 mm) and varied from 23 mm (4-180 mm) for invasive cancers to 32 mm (0-100 mm) for DCIS. Specimen margins were involved in 12.6% of the cases; 10.5% of invasive ductal, 14.7% of DCIS, and 20.9% of invasive lobular. The overall breast conservation rate was 92% and varied from 87.4% for DCIS to 93.5% for the invasive cancers. Thirty-one patients (8.9%) developed one or more postoperative complications, inducing a delay in postoperative treatments in 4.6% of patients. The median follow up was 55 months. The cumulative 5-year incidences for local, regional, and distant recurrences were 2.2%, 1.1%, and 12.4%, respectively. CONCLUSIONS: Oncoplastic breast reductions allow wide resections with free margins and can be used for large cancers as an alternative to mastectomy.

Pattern of relapse in low-risk breast cancer patients followed within a community care network.

International guidelines have set the frame and methods of patients' surveillance after early breast cancer (BC) treatment. Since 1998, delegation of low-risk BC patients follow-up to nonhospital practitioners has been developed within a care network in the Paris region. We used the Gynecomed care network digital database to describe the characteristics of oncological events which occurred in the cohort, and to assess the quality of BC follow-up in relapsing patients. Events were defined as any local, contralateral, or metastatic recurrence, as well as second cancer or death due to any cause. We developed a ranked evaluation method of our surveillance program. Among the 3019 patients followed in the network, 116 (4.3%) patients had 116 events. Median follow-up was 7.1 years (0-51). First events were local-regional relapses, contralateral BCs, metastatic events, second primaries in respectively 52, 26, 14, 24 cases. During the first 5 years, 68.4% of surveillance visits were performed on time, 13.5% were behind schedule and 18.1% were not performed, while 79.1% of mammographies were performed on time, 7.7% behind schedule, and 13.2% were not performed. On schedule examinations allowed diagnosis of 77% of the local-regional, ipsilateral relapses or contralateral BCs, including 38 (69%) discovered by mammographies and 17 (31%) by clinical examination. A nonhospital practitioner care network is able to comply with good surveillance practices and deliver high quality surveillance, in accordance with international guidelines. Delegation of low-risk BC surveillance to nonhospital practitioners is reliable.

Evidence for the use of robotically assisted surgery in gynecologic cancers.

PURPOSE OF REVIEW: Robotically assisted laparoscopy has been introduced in the armamentarium of gynaecologic oncology surgeons. A lot of studies compared robotic surgery and laparotomy when the real issue is to demonstrate the interest and added value of robotically assisted laparoscopy versus standard laparoscopy. In this review, we will describe the most meaningful indications and advantages of robotically assisted laparoscopy in gynaecologic oncology. RECENT FINDINGS: The learning curve for advanced procedures in robot-assisted laparoscopy is shorter and easier than with the standard laparoscopy, especially for beginners. In most of the series, operating time is longer with robot, but complication rates are often decreased, especially in obese patients with a conversion rate to laparotomy that is decreased compared with standard laparoscopy. Robot-assisted laparoscopy can be used for surgery of high-risk endometrial cancer, staging of early-ovarian cancer, and pelvic exenteration in case of recurrent malignancies. Furthermore, more recent robots allow performing sentinel node biopsy in endometrial or cervical cancer using fluorescence detection with indocyanine green. SUMMARY: The spreading of robotic surgery led to an enhancement of minimal invasive surgical approach in general, and to the development of new indications in gynaecologic oncology. The superiority of robot-assisted laparoscopy still has to be demonstrated with properly designed trials.

Positive Margins After Oncoplastic Surgery for Breast Cancer.

BACKGROUND: Oncoplastic techniques applied to breast-conserving surgery (BCS) allow large-volume resections without compromising cosmetic results. Level II oncoplastic techniques are based on mammoplasties. When required, they allow resection of more than 20 % of the breast volume; however, a subgroup of these patients will still have positive margins. The clinical management of positive margins after level II oncoplastic surgery (OPS) is a challenge. METHODS: All patients who had undergone level II oncoplastic techniques at The Paris Breast Center between 2004 and 2013 were reviewed. The choice of the optimal mammoplasty technique was based on the tumor location and the 'quadrant per quadrant atlas'. RESULTS: A total of 277 level II oncoplastic techniques were performed on 272 patients. The mean tumor size was 26 mm (range 2-160 mm), with a mean resected weight of 175 g (range 50-1540 g). The rate of positive margins was 11.9 %. Risk factors for positive margins identified in univariate analysis were histologic subgroup, tumor size, T stage and grade. In multivariate analysis, only patients with invasive lobular carcinoma had a significantly higher risk of positive margins. A second operation was required in 33 cases, and a third operation was required in three cases because of positive margins. Final breast conservation rate was 91 %. CONCLUSIONS: Level II OPS results in a low positive margin rate despite large tumor size. Patients with involved margins can be offered a second BCS if the remaining volume allows this.

Rates of Neoadjuvant Chemotherapy and Oncoplastic Surgery for Breast Cancer Surgery: A French National Survey.

BACKGROUND: The current retrospective study was intended to obtain up-to-date and comprehensive data on surgical practice for breast cancer throughout France, including neoadjuvant chemotherapy (NAC) and the more recent surgical techniques of oncoplastic surgery (OPS). METHODS: In June 2011, e-mail surveys were sent to 33 nationally renowned breast cancer surgeons from French public or private hospitals. The questionnaire focused on all the new cases of breast cancer treated in 2010. It included questions regarding surgical practices, with special emphases on NAC and OPS and other surgical characteristics. RESULTS: The overall response rate for the survey was 72.7 %. The total number of breast cancer cases from the survey was 13,762, which constitutes 26.2 % of the total incidence in 2010. Breast-conserving surgery (BCS) was performed for 71.0 % of the patients, and the results were similar throughout the types of practices. Of these patients, 13.9 % received OPS, either upfront or after NAC. Mastectomy was performed for 29.0 % of the patients, which is consistent with French official numbers. Among all patients, 16.3 % underwent surgery after NAC. CONCLUSION: To the authors' knowledge, there are no publications of national figures on NAC or OPS rates to date. They are convinced that this study offers real-life surgical care information on a large population and covers France's breast cancer surgical landscape. Mastectomy rates in France remain stable and consistent with those in other European countries. However, additional large-scale retrospective studies are required to confirm these figures and further explore NAC and OPS rates as well as surgical practice characteristics.

Oncoplastic surgery: pushing the limits of breast-conserving surgery.

In recent decades, the surgical management of breast cancer has steadily and considerably improved. Mutilating procedures have given way to more individualized surgical approaches aiming to preserve the breast as much as possible. For large tumors, preoperative chemotherapy is a major tool, but emerging oncoplastic surgery techniques are also a new approach in the armamentarium of breast cancer surgery, as a third option between conventional breast-conserving surgery and mastectomy. As this new treatment modality allows wider margin excision, it reduces the need for re-excision procedures and possibly increases breast conservation rates by extending the indications of breast-conserving surgery. This review will provide an overview of current practices and clinical data available to date on oncoplastic surgery.

Robotic extraperitoneal paraaortic lymphadenectomy in gynecological cancers: feasibility, safety, and short-term outcomes of isolated and combined procedures.

OBJECTIVE: The aim of our study was to report the technique, the feasibility, and perioperative results of robotic extraperitoneal paraaortic lymphadenectomy in gynecological cancers performed for isolated or combined procedures. METHODS: This is a retrospective study of 24 consecutive patients undergoing robotic extraperitoneal paraaortic lymphadenectomy using the Da Vinci Surgical system (Intuitive Inc, Sunnyvale, CA) (cervical cancer, n = 15; high-risk endometrial cancer, n = 8; and ovarian cancer, n = 2, including 1 synchronous tumor). Extraperitoneal paraaortic lymphadenectomy was performed using the surgical technique previously described by laparoscopy. RESULTS: Of the 24 included patients, 12 patients had isolated robotic extraperitoneal paraaortic lymphadenectomy, whereas the others underwent the following associated procedures: total hysterectomy with bilateral salpingo-oophorectomy, pelvic lymphadenectomy, and omentectomy (n = 7); pelvic transperitoneal lymphadenectomy (n = 3), laparotomic Bricker procedure (n = 1), and colpectomy (n = 1). The median age of patients was 55 (42-64) years, and body mass index was 24.1 kg/m (20.9-26.1). The operation was completed in all patients except three with associated procedures. Perioperative difficulties were encountered in 9 patients (gas leakage, n = 7; adhesions, n = 2; and dissection difficulties, n = 1). The number of removed paraaortic lymph nodes was 18 (14-25). The operating times were 180 (150-210) minutes for isolated extraperitoneal paraaortic lymphadenectomy and 240 (180-300) minutes in case of associated procedures. There were 2 intraoperative (pneumothorax and renal artery injury) and 5 postoperative (3 grades 1-2 and 2 grade 3) complications. CONCLUSIONS: If robotic-assisted extraperitoneal paraaortic lymphadenectomy seems feasible in case of isolated procedure, further studies are required to prove its benefit compared with conventional laparoscopy.

Lower-limb drainage mapping for lymphedema risk reduction after pelvic lymphadenectomy for endometrial cancer.

OBJECTIVES: Pelvic lymphadenectomy is associated with a significant risk of lower-limb lymphedema. In this proof-of-concept study, we evaluated the feasibility of identifying the lower-limb drainage nodes (LLDNs) during pelvic lymphadenectomy for endometrial cancer. Secondary objectives were to map lower-limb drainage and to assess the diagnostic value of our mapping technique. METHODS: This prospective study included patients with endometrial cancer requiring pelvic lymphadenectomy, without neoadjuvant radiotherapy or chemotherapy and without history of lower-limb surgery. A radiopharmaceutical was injected into both feet on the day before surgery. LLDNs were identified using preoperative lymphoscintigraphy and intraoperative isotopic probe detection, then removed before complete pelvic lymphadenectomy. LLDNs and pelvic lymphadenectomy specimens underwent separate histological analysis. RESULTS: Of the 12 patients with early-stage endometrial cancer, 10 underwent preoperative lymphoscintigraphy, which consistently identified inguinal, femoral, and pelvic LLDNs (detection rate: 100%). The intraoperative detection rate was 83% (10/12). Median number of hot nodes per patient was 5 nodes (range: 3-7) on the right and 3 nodes (range: 2-6) on the left. Of 107 LLDNs, 106 were in the external iliac area, including 38 in the lateral group and 45 in the intermediate and medial groups. None of the patients had node metastases at any site. No early complications related to the technique occurred. CONCLUSION: Our mapping technique appears feasible, safe, and associated with a high LLDN identification rate. LLDN mapping may allow the preservation of LLDNs, thereby decreasing the risk of lower-limb lymphedema and improving quality of life.

Level 2 oncoplastic surgery for lower inner quadrant breast cancers: the LIQ-V mammoplasty.

BACKGROUND: Oncoplastic surgical techniques offer an option of breast conserving surgery for larger tumors with the use of glandular reshaping to prevent postoperative deformity. A technique for the excision of lower inner quadrant tumors via a V incision is described, the lower-inner quadrant-V (LIQ-V) mammoplasty, and the results of a pilot study are reported. METHODS: Retrospective collection of pre- and postoperative data was collected from patients undergoing a LIQ-V mammoplasty for a LIQ tumor. RESULTS: Twenty-two patients were operated on between 2004 and 2011 at a mean age of 58 years. The mean follow-up was 55 months. The mean resection weight was 101 g for tumors ranging in size from 4 to 31 mm. The margins were clear in 95% of cases. There was one case of local recurrence and metastatic disease. The cosmetic outcome was judged as excellent in 68% of cases, and no patient required further ipsilateral or contralateral symmetrizing surgery. DISCUSSION: The deformity often associated with tumors of the LIQ is adequately addressed by this new technique. It has a complication rate comparable to other mammoplasty series and a high rate of clear resection margins. Many oncoplastic surgery techniques are based on inverted T mammoplasty, but these are not suited for all tumor locations. The LIQ-V mammoplasty is an adaptation of the standard techniques that best suit the LIQ. It is oncologically safe and provides disease-free margins, and although the resection volumes are large, the cosmetic outcome is not compromised.

Diagnostic performance of one-step nucleic acid amplification for intraoperative sentinel node metastasis detection in breast cancer patients.

The purpose of this prospective multicenter study was to assess one-step nucleic acid amplification (OSNA) for intraoperative sentinel lymph node (SLN) metastasis detection in breast cancer patients, using final histology as the reference standard. OSNA results were also compared to intraoperative histology SLN evaluation and to standard clinicopathological risk markers. For this study, fresh SLNs were cut in four blocks, and alternate blocks were used for OSNA and histology. CK19 mRNA copy number was categorized as strongly positive, positive or negative. Positive histology was defined as presence of macrometastasis or micrometastasis. When discrepancies occurred, the entire SLNs were subjected to histological studies and the node lysates to additional molecular studies. Five hundred three SLN samples from 233 patients were studied. Mean time to evaluate two SLNs was 40 min. Sensitivity per patient was 91.4% (95% CI, 76.9-98.2%), specificity 93.3% (95% CI, 88.6-96.6%), positive likelihood ratio 13.7 and negative likelihood ratio 0.1. Sensitivity was 63.6% for frozen sections and 47.1% for touch imprint cytology. Both methods were 100% specific. Positive histology and positive OSNA were significantly associated with highest clinical stage, N1 status and vascular invasion; and OSNA results correlated with HER2/neu status and benefited patients with negative histology. These findings show that OSNA assay can allow detection of SLN metastasis in breast cancer patients intraoperatively with a good sensitivity, thus minimizing the need for second surgeries for axillary lymph node detection.

Oncoplastic technique for the elimination of the lateral "dog ear" during mastectomy.

Following a mastectomy, both the cosmetic and functional results can be impaired by the presence of a lateral "dog ear." This is a particular problem in women with a large body habitus giving an increased amount of adipose tissue lateral to the breast. The standard approaches to this operation of horizontal or oblique incisions often results in an uncomfortable, unsightly lateral "dog ear". We describe a modification to the standard mastectomy incision that allows extensive excision of the lateral adipose tissue, re-draping the skin over the chest wall, thus eliminating the "dog ear." The mastectomy is performed through two oblique incisions originating in the axillary skin crease encompassing the nipple areolar complex, followed by extensive lateral fat excision. A distance of 2-3 cm is kept between the superior limit of the two incisions. At closure the lateral skin flap is advanced superiomedially on the chest wall without tension. This simple and reproducible technique improves cosmesis and patient satisfaction following modified radical mastectomy by eliminating the lateral "dog ear."

Avoiding post mastectomy lateral "Dog Ears" by an L incision and lipoaspiration: The Paris Breast Center technique.

BACKGROUND: Lateral dog ear after mastectomy in overweight or large breasted patients is a source for patient discomfort and is aesthetically unpleasing. Although many different techniques have been proposed, none of them have emerged as standard. In 2012, the authors published their mastectomy technique based on an inverted L-scar incision and closure with a lateral skin flap advanced supero-medially onto the chest wall. Authors sought to report their experience with this technique in patients with wide or large breasts operated with mastectomy without immediate breast reconstruction. As a refinement to their initial technique, they added lipoaspiration to the lateral chest wall. METHODS: A retrospective study identified 43 patients operated on using the L incision and lipoaspiration from January 2015 to January 2021. Patient and tumor characteristics, operative details, post-operative results, and complications were recorded. Patients were followed-up and assessed for arm motion restriction, lymphedema, and recurrence. RESULTS: The mean age was 68 years; the mean BMI was 29 kg/m 2. The mean follow-up was 32 months. The mean weight of the mastectomy specimen was 1009 g and the mean aspirated volume in the lateral chest wall was 450 mL. One patient had a hematoma, four patients had seroma, and one patient developed a minor wound dehiscence. No skin necrosis or arm movement restriction was observed. Two patients developed mild lymphedema. Three patients underwent delayed breast reconstruction. CONCLUSION: The proposed technique is a safe and effective method to avoid lateral dog deformity after mastectomy, achieving both functional and cosmetic outcomes.

Fat Grafting before Delayed Prophylactic Mastectomy and Immediate Implant Reconstruction for Patients at High Risk of Complications.

SUMMARY: The majority of patients undergoing bilateral prophylactic mastectomy request immediate implant-based breast reconstruction. Some patients, especially those with prior radiotherapy, are at increased risk of early cutaneous complications and implant loss. The authors developed the technique of primary fat grafting before delayed prophylactic mastectomy to minimize early complications for selective high-risk patients. They have completed 21 cases in 14 patients, 10 of whom had previous lumpectomy and radiation treatment for breast cancer. A single session of fat grafting, with a median injection volume of 250 ml (interquartile range, 200 to 300 ml), was performed a median period of 19 weeks (interquartile range, 16 to 28 weeks) before prophylactic mastectomy. All cases were direct-to-implant reconstruction using textured silicone implants. The median implant volume was 410 ml (interquartile range, 318 to 450 ml). A minor early complication developed in 14 percent of cases (three of 21), with no early implant loss. At a median follow-up of 9 months (interquartile range, 5 to 27 months), the authors found no cases of implant loss and an excellent or good aesthetic outcome (score of 5 or 4) in 16 of 21 cases (76 percent). Fat grafting before prophylactic mastectomy is a novel strategy to minimize early complications and avoid implant loss in patients at high risk of postoperative complications. . CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Improving breast cancer surgery: a classification and quadrant per quadrant atlas for oncoplastic surgery.

BACKGROUND: Oncoplastic surgery (OPS) has emerged as a new approach for extending breast conserving surgery (BCS) possibilities, reducing both mastectomy and re-excision rates, while avoiding breast deformities. OPS is based upon the integration of plastic surgery techniques for immediate reshaping after wide excision for breast cancer. A simple guide for choosing the appropriate OPS procedure is not available. OBJECTIVE: To develop an Atlas and guideline for oncoplastic surgery (OPS) to help in patient selection and choice of optimal surgical procedure for breast cancer patients undergoing BCS. METHODS: We stratify OPS into two levels based on excision volume and the complexity of the reshaping technique. For resections less than 20% of the breast volume (level I OPS), a step-by-step approach allows easy reshaping of the breast. For larger resections (level II OPS), a mammoplasty technique is required. RESULTS: We identified three elements that can be used for patient selection and for determination of the appropriate OPS technique: excision volume, tumor location, and glandular density. For level II techniques, we defined a quadrant per quadrant Atlas that offers a different mammoplasty for each quadrant of the breast. CONCLUSIONS: OPS is the "third pathway" between standard BCS and mastectomy. The OPS classification and Atlas improves patient selection and allows a uniform approach for surgeons. It proposes a specific solution for different scenarios and helps improve breast conservation outcomes.

Salvaging the infected breast implant: results of a retrospective series of 80 consecutive cases.

BACKGROUND: Breast implants are widely used in reconstruction after breast cancer. Infection after implant reconstruction is a major complication, with rates ranging from 5 to 30%. This rate is less for pure cosmetic augmentation. Historically, infection of an implant mandated implant removal for sepsis control. An alternative is to attempt to salvage the infected implant. This path can be a long one, requiring surgery for washouts and prolonged antibiotic therapy. This article documents our experience of infected implant salvage over the last 13 years. METHODS: We conducted a retrospective analysis of all patients who developed a breast implant infection between January 2005 and January 2018. All patients had both clinical signs of infection and a positive bacteriological sample. Patients were divided into two groups: upfront medical therapy (including those requiring secondary surgical salvage) and primary surgery. The salvage procedure was defined as successful when the implant was still in place three months after the initial reconstruction. RESULTS: Eighty patients were included: 77 in the medical group and 3 in the surgical group. Overall, implant salvage was achieved in 88.8% of women (n=71). Of these, 73.8% (n=59) underwent medical treatment alone and 15% (n=12) underwent medical treatment followed by surgical management. The main causative organism was staphylococcus in 81.2%. When the infection was caused by a coagulase-negative staphylococcus, the rate of success was 98% (p<0.003). CONCLUSIONS: This case series reports that salvage of an infected breast implant was achievable in up to 90% of women presenting with a documented infection, the majority requiring antibiotic management only. Early intervention is central to success.

Breast-conserving therapy can be offered to women with prior breast augmentation.

INTRODUCTION: Breast cancer in women with cosmetic breast implants is increasingly common. Over the past decade, there has been a push for mastectomy and reconstruction in these patients, based on a fear of poor aesthetic results from small breast volume, and radiation-induced capsular contracture. At the Paris Breast Centre, augmented women routinely undergo lumpectomy with whole-breast irradiation (BCT). MATERIALS AND METHODS: A consecutive cohort of 50 augmented women, who had attempted BCT for early breast cancer at our institution between 2003 and 2018, were retrospectively identified. Post-treatment complications, oncologic outcomes, capsular contracture rates, long-term cosmetic outcomes, and patient-reported outcomes were evaluated. RESULTS: The median follow-up was 51 months. Margins were involved in 7 women (14%); 4 of whom underwent successful re-excision, and 3 had a mastectomy, for an early mastectomy rate of 6%. There were no early complications, nor cases of early implant loss. Long-term aesthetic results were evaluated using our 5-point scale: An excellent (5), or good (4) result was obtained in 68%. Significant capsular contracture (Baker grade 3 or 4) developed in 34%, of which, 5 women underwent capsulotomy and fat grafting; 4 of 5 downstaging their Baker grade. The estimated 5-year local recurrence rate was 2.3%. Ninety-five percent of participants would recommend BCT to augmented women. CONCLUSION: BCT is feasible and safe in augmented women with good long-term aesthetic results, and should be considered to avoid unnecessary mastectomy.

Disseminated tumor cells of breast cancer patients: a strong prognostic factor for distant and local relapse.

PURPOSE: Clinical significance of disseminated tumor cells (DTC) in bone marrow of early breast cancer patients has been reported, but improvements in detection methods are needed. EXPERIMENTAL DESIGN: Bone marrow aspirates from 621 patients with stage I to III breast cancer were screened for cytokeratin-positive (CK+) cells. CK+ cells were categorized into DTC only if they had specific morphologic features of tumor cells. Bone marrow status and clinical and pathologic variables of the patients were correlated with clinical outcome after a median follow-up of 56 months. RESULTS: DTC and non-DTC CK+ cells were detected in 15% and 34% of patients, respectively, with no correlation with clinical and pathologic variables. On univariate analysis, DTC detection was associated with a poorer distant metastasis-free survival (DMFS; P = 0.0013) and overall survival (OS; P = 0.005). Moreover, DTC detection was also associated with local relapse-free survival (P = 0.0009). On multivariate analysis, DTC detection was an independent prognostic factor for DMFS, local relapse-free survival, and OS. There was no significant interaction between DTC detection and hormonal receptors status (P = 0.34). Non-DTC CK+ cells had no clinical significance. CONCLUSION: DTC detection is a powerful prognostic marker for DMFS and OS in early breast cancer patients and can be individualized from irrelevant non-DTC CK+ cells by morphologic criteria. Biologically, despite high rates of systemic adjuvant therapy and locoregional irradiation in this series, DTC detection remains a prognostic factor of distant and, more strikingly, of local relapse, in favor of resistance to treatment of locally or distant disseminated cancer cells in DTC-positive patients.
