RESUMO

INTRODUCTION: Nipple-sparing mastectomy (NSM) is a surgical procedure increasingly performed for breast cancer or risk reduction surgeries. The site of skin incision seems to affect not only cosmesis but also technical ease in operating and vascular viability of the nipple. We present a series of patients who underwent a modified vertical surgical approach for NSM, which resulted to be safe, reliable, and with good esthetic results. MATERIALS AND METHODS: From December 2016 to February 2019, 27 "Hook Shape" incision NSMs were performed. All patients underwent an immediate subcutaneous muscle-sparing reconstruction with tissue expander covered by a titanium-coated polypropylene mesh, followed by a second surgical step with expander substitution and lipofilling on the definitive implant when indicated. Preoperative and postoperative BREAST-Q patient-reported outcomes measure was performed in all cases. RESULTS: Postoperative morbidity was evaluated: One patient developed seroma and another presented a systemic infection that resolved with intravenous infusion of antibiotics. One patient experienced vertical wound dehiscence, recovered after conservative treatment and without implant exposure. No implant loss was observed. Nipple-areola complex necrosis or ischemia rate was 0%. The BREAST-Q outcomes reported significant increases in the overall satisfaction with breast (p < 0.05), psychosocial well-being (p < 0.05), and sexual well-being (p < 0.05) sections. Scores in the physical impact of surgery section appeared to decline from preoperative to postoperative evaluations, with no statistically significant results. CONCLUSION: The mastectomy incision pattern can burden the surgical challenge, impact vascular viability of the nipple and significantly affect the aesthetic outcomes in breast reconstruction. We report our experience with an alternative approach for NSM, which appears a safe, practical, and reproducible method for patients with small- to medium-sized breasts and little/medium ptosis (grade I or II).

RESUMO

To investigate pharmacogenetic interactions among VEGF-A, VEGFR-2, IL-8, HIF-1α, EPAS-1, and TSP-1 SNPs and their role on progression-free survival (PFS) in metastatic breast cancer (MBC) patients treated with bevacizumab plus first-line paclitaxel or with paclitaxel alone. Analyses were performed on germline DNA, and SNPs were investigated by real-time PCR technique. The multifactor dimensionality reduction (MDR) methodology was applied to investigate the interaction between SNPs. The present study was an explorative, ambidirectional cohort study: 307 patients from 11 Oncology Units were evaluated retrospectively from 2009 to 2016, then followed prospectively (NCT01935102). Two hundred and fifteen patients were treated with paclitaxel and bevacizumab, whereas 92 patients with paclitaxel alone. In the bevacizumab plus paclitaxel group, the MDR software provided two pharmacogenetic interaction profiles consisting of the combination between specific VEGF-A rs833061 and VEGFR-2 rs1870377 genotypes. Median PFS for favorable genetic profile was 16.8 vs. the 10.6 months of unfavorable genetic profile (p = 0.0011). Cox proportional hazards model showed an adjusted hazard ratio of 0.64 (95% CI, 0.5-0.9; p = 0.004). Median OS for the favorable genetic profile was 39.6 vs. 28 months of unfavorable genetic profile (p = 0.0103). Cox proportional hazards model revealed an adjusted hazard ratio of 0.71 (95% CI, 0.5-1.01; p = 0.058). In the 92 patients treated with paclitaxel alone, the results showed no effect of the favorable genetic profile, as compared to the unfavorable genetic profile, either on the PFS (p = 0.509) and on the OS (p = 0.732). The pharmacogenetic statistical interaction between VEGF-A rs833061 and VEGFR-2 rs1870377 genotypes may identify a population of bevacizumab-treated patients with a better PFS.

RESUMO

Post-operative implant infection is generally rare after breast augmentation, but it can occur in up to 35% of cases in post-mastectomy breast reconstruction. Standard treatment consists in the administration of antibiotics, implant removal, and delayed prosthesis replacement leading to multiple operations, with a negative impact on patient's clinical, economical, and psychological outcomes. There is little information published in the literature on the management of periprosthetic infection following pre-pectoral reconstructions. Capsule's removal from a pre-pectoral plane brings the risk of excessive tissue thinning and the compromise of skin flaps viability. In this preliminary multi-center case series, eight patients diagnosed with implant infection following oncological mastectomy and two-stage heterologous pre-pectoral breast reconstruction underwent the same protocol, consisting in tissue expander removal and conservative surgical revision supplemented by an antibiotate pulse lavage of the pocket surface. All patients achieved a successful infection resolution with immediate prosthesis replacement switching the temporary expander to definitive implant. No additional surgical revision was registered during follow-up. The intermittent irrigation is meant to disrupt the biofilm structure and restore antibiotic susceptibility. Moreover, pulse lavage allows the cleansing of the prosthetic capsule, thus avoiding the vascular stress associated with subcutaneous capsulectomy. To the best of our knowledge, this is the first series reporting on the use of Pulsavac in periprosthetic infection following pre-pectoral breast reconstruction, in an attempt to set the basis for an alternative conservative protocol to manage breast implant infection. A thorough literature review on pulse lavage in breast surgery was carried out.

RESUMO

BACKGROUND: Implant-based reconstruction is the most performed breast reconstruction, and both subpectoral and prepectoral approaches can lead to excellent results. Choosing the best procedure requires a thorough understanding of every single technique, and proper patient selection is critical to achieve surgical success, in particular when dealing with prepectoral breast reconstruction. METHODS: Between January of 2014 and December of 2018, patients undergoing mastectomy and eligible for immediate prepectoral breast reconstruction with tissue expander or definitive implant, were selected. The Prepectoral Breast Reconstruction Assessment score was applied to evaluate patient-related preoperative and intraoperative risk factors that could influence the success of prepectoral breast reconstruction. All patients were scored retrospectively, and the results obtained through this assessment tool were compared to the records of the surgical procedures actually performed. RESULTS: Three hundred fifty-two patients were included; 112 of them underwent direct-to-implant immediate reconstruction, and 240 underwent the two-stage procedure with temporary tissue expander. According to the Prepectoral Breast Reconstruction Assessment score, direct-to-implant reconstruction should have been performed 6.2 percent times less, leading to an increase of 1.4 percent in two-stage reconstruction and 4.8 percent in submuscular implant placement. CONCLUSIONS: To date, there is no validated system to guide surgeons in identifying the ideal patient for subcutaneous or retropectoral breast reconstruction and eventually whether she is a good candidate for direct-to-implant or two-stage reconstruction. The authors processed a simple risk-assessment score to objectively evaluate the patient's risk factors, to standardize the decision-making process, and to identify the safest and most reliable breast reconstructive procedure. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

RESUMO

BACKGROUND: We evaluated the aesthetic outcomes and quality of life of patients who underwent neurotomy of the lateral and medial branch of the pectoralis nerve for animation deformity after breast reconstruction. MATERIAL AND METHODS: Health-related quality of life questionnaire and cosmetic outcome evaluation were conducted using the preoperative and the postoperative BREAST-Q modules for reconstructive surgery. An external author also assessed the general aesthetic outcome before and after surgery. RESULTS: Sixty-two patients with animation deformity after breast reconstruction were enrolled: 43 in group 1 (second-stage breast reconstruction), 10 in group 2 (permanent breast prosthesis), and 9 in group 3 (Baker III-IV capsular contraction). Patients scored high level of satisfaction with outcome concerning all aspects of the survey. Overall satisfaction with breast was significantly increased after surgery in all the 3 groups, whereas physical well-being was improved in group 1 and group 3 and psychosocial well-being was improved in group 1. General outcome evaluation by an external author, compared with the preoperative condition, also showed significant improvement. CONCLUSIONS: Section of the lateral and medial branches of the pectoralis nerve represents an easy and reproducible technique, associated with low morbidity and very good results in terms of patient satisfaction, comfort, and hospitalization.

RESUMO

BACKGROUND: The latissimus dorsi (LD) flap represents one of the most reliable methods for autologous breast reconstruction. However, in many patients, the exclusive use of this technique may not guarantee the restoration of an adequate volume and projection. We report our experience with the extended latissimus dorsi kite flap (ELD-K flap), an alternative surgical approach to maximize the volume of the fleur-de-lis pattern LD flap, for total autologous breast reconstruction. METHODS: Between 2016 and 2018, 23 patients were subjected to mastectomy and immediate autologous reconstruction with "extended latissimus dorsi kite flap" (ELD-K flap), technique that employs an extended version of the LD musculocutaneous flap, based on the skeletonized thoracodorsal pedicle and a trilobate skin incision with an inferiorly based vertical branch. The BREAST-Q questionnaire was administered preoperatively, and one year after surgery to evaluate the quality of life results of the patients. BREAST-Q latissimus dorsi module was also provided. RESULTS: Average body mass index was 29.7 kg/m2 (range 25-40 kg/m2). Mild complications occurred in only six cases, and eight patients underwent treatment to improve the donor site scar outcome. Patients indicated high scores in quality of life measures with an increase in all BREAST domains from the preoperative to the postoperative period. A statistically significant increase (p < 0.05) was noted in: "overall satisfaction with breasts" (p < 0.05), "psychosocial well-being" (p < 0.05), "physical impact of the surgery" (p < 0.05). Within the LD module, participants reported a mean score of, respectively, 73.8 and 67.9 for "satisfaction with back" and "satisfaction with shoulder and back function" domains. CONCLUSIONS: The extended incision allows the recruitment of additional tissue to provide enough volume to complete the reconstruction without implants. The isolation of the vascular pedicle allows for extreme freedom and mobilization of the flap, ensuring adequate filling of the breast. ELD-K flap may expand the indications for a total autologous LD immediate breast reconstruction, representing an additional and reliable alternative in selected cohorts of patients.

RESUMO

BACKGROUND: The main goal of oncoplastic breast-conserving surgery (OBCS) is to obtain tumor-free resection margins after cancer excision with satisfactory cosmetic results. Positive tumor margins are associated with high rates of tumor recurrence requiring reoperation. The aim of this prospective clinical trial was to demonstrate the reliability of intraoperative ultrasound (IOUS) to obtain tumor-free resection margins in OBCS. PATIENTS AND METHODS: Between December 2016 and March 2018, data from 130 patients with by T1-2 breast cancer, either invasive or in situ, who underwent OBCS were prospectively collected. The oncoplastic surgeon performed IOUS in the operating theater to localize the lesion and mark its skin projection. Then specimens were examined to assess the presence of the lesion and margin adequacy. Definitive histologic reports were reviewed, with a focus on margin status. RESULTS: All patients experienced oncoplastic approaches, and lesions were always found on the specimen at the histologic report. In 126 cases (97%), margins were considered adequate. In 17 cases (13%), IOUS showed positive margins, and resection was contextually enlarged. In 12 of these (9%), the pathologic report confirmed the need for enlarged resection. This study shows that IOUS-guided surgery can obtain a high percentage of tumor-free resection margins in OBCS without scheduling conflicts between radiology, nuclear, and surgery departments. Full cooperation between radiologists and oncoplastic surgeons is required to achieve high-standard oncologic and reconstructive outcomes. CONCLUSION: IOUS represent an additional tool for the breast surgeon to improve margin-free management of neoplastic lesions, preventing reoperations in patients undergoing oncoplastic surgery.

RESUMO

BACKGROUND: In the last decade, development of videolaparoscopic surgery allowed several operations to be performed with minimally invasive techniques, making them less invasive and painful. Neck surgery was also involved in this effort, in spite of the skepticism shown by some authors. STUDY DESIGN: Minimally invasive video-assisted thyroidectomy was developed in 1998, and since then, about 600 operations have been performed. Access was the same as was previously described for parathyroidectomy; it was based on a small central incision (1.5 cm) and on external retraction without neck insufflation. RESULTS: From July 1998 to October 2003, 579 patients were selected from 5,450 for minimally invasive video-assisted thyroidectomy. The operation consisted of a total thyroidectomy in 312 patients and lobectomy in 267 patients. Mean operative time was 41 +/- 19.5 minutes (range 15 to 120 minutes) for lobectomy and 51.6 +/- 18.8 minutes (range 30 to 140 minutes) for total thyroidectomy. Postoperative hospital stay was 24 hours (overnight discharge) for all patients. Complications were postoperative bleeding (0.1%), recurrent nerve palsy (1.3%), and definitive hypoparathyroidism (0.2%). CONCLUSIONS: After 5 years of experience using this approach for various indications, we achieved a good esthetic result with an operative time comparable to that of conventional open surgery. Minimally invasive video-assisted thyroidectomy was found to be a safe operation, with advantages over traditional procedures represented by better cosmetic outcomes and postoperative course, as demonstrated by visual analogue scales and statistically analyzed numeric scales.

RESUMO

BACKGROUND: Parathyroid surgery for sporadic primary hyperparathyroidism (pHPT) can be accomplished with local/regional anesthesia and intraoperative monitoring of intact parathyroid hormone without exclusion criteria through a 1.0- to 1.25-inch (2.5- to 3.2-cm) incision (MIPL) in a high proportion of patients. METHODS: One hundred thirty-one consecutive patients with pHPT were offered MIPL. One hundred three patients elected to have this procedure. Patients were not excluded because of inadequate localization, previous parathyroid surgery, or need for concomitant thyroid surgery. Preoperative localization with ultrasound and/or sestamibi-single photon emission computed tomography scan was done in all patients. Almost all patients had intraoperative monitoring of intact parathyroid hormone (IMPTH). RESULTS: MIPL was accomplished in 89 of these 103 patients (86.4%), but 14 required conversion to general anesthesia. The main reasons for conversion were concomitant thyroid surgery, no positive preoperative localization, and previous parathyroid surgery. This procedure was accomplished in 13 patients requiring a bilateral procedure, 5 patients requiring thyroid surgery, 4 patients with no positive preoperative localization, and in 3 patients with previous parathyroid surgery. The complications of MIPL were comparable to the traditional bilateral exploration with general anesthesia. No patient experienced permanent hypoparathyroidism or postoperative bleeding. Two patients had transient recurrent laryngeal nerve paresis, and surgery failed to correct hypercalcemia in 5 (4.9%) of the patients. There appears to be less need for antiemetic medication in the MIPL patients compared with patients who had general anesthesia. CONCLUSIONS: Parathyroid surgery for sporadic pHPT can be accomplished through a 1.0- to 1.25-inch (2.5- to 3.2-cm) incision with local/regional anesthesia, without exclusion criteria. Accurate preoperative localization, particularly localization to the same site by both ultrasound and 99mTc-sestamibi scan, and IMPTH can limit the surgery to a unilateral approach. One should be cautious in proceeding with MIPL in patients with need for concomitant thyroid surgery, no preoperative localization, or previous parathyroid surgery.
