A New Convenient Incision Model of the Nipple-Sparing Mastectomy: Lateralized Parabolic Multiplanar Incision.

BACKGROUND: In this study, a lateralized parabolic multiplanar incision was defined. It was aimed to reduce necrosis in the nipple-areola complex (NAC) and, in the long run, to prevent the scar from pulling the areola laterally by maintaining healthy skin tissue between the scar and the areola and preserving the natural round appearance of the areola. Moreover, we purposed the scar not to be visible from the anterior view. METHODS: The study included 243 patients who underwent nipple-sparing mastectomy and immediate implant-based breast reconstruction. The incision was made 4-5 cm away from the lateral border of the NAC. The incision was completed after passing the anterior axillary line by drawing a parabolic curve in superolateral axis. RESULTS: The mean follow-up period was 24.6 months, and the mean age of the patients was 42.3 years. Full-thickness necrosis of the NAC occurred in 3.6% of breasts. In long-term follow-ups, the incision scar measured an average length of 8.6 cm. None of the patients had lateral displacement of the NAC. The NAC preserved its round appearance, except for 12 breasts that had full-thickness NAC necrosis. Ten breasts had an unnatural breast appearance. CONCLUSION: The lateralized parabolic multiplanar incision is an ideal incision model for nipple-sparing mastectomy, as it allows for the exposure and reconstruction of all breast quadrants. We maintain areolar circulation; there are no visible scars when viewed anteriorly. Furthermore, it prevents lateral displacement of the NAC, ensuring that the natural round form of the NAC is not distorted.

Adherence to adjuvant tamoxifen and associated factors in breast cancer survivors.

PURPOSE: Adjuvant endocrine therapy reduces the recurrence and mortality of early hormone receptor-positive breast cancer in both pre- and postmenopausal women. The aim of this study was to investigate adjuvant tamoxifen adherence and associated factors in breast cancer survivors. METHODS: This descriptive, prospective study was conducted in 2019-2020 with the participation of 531 women who survived breast cancer and were under follow-up at the Senology Institute of a hospital in Istanbul. Inclusion criteria were having completed treatment for early hormone receptor-positive breast cancer, being prescribed tamoxifen, and being 18 years or older. Data were collected using a patient information form and the Morisky Medication Adherence Scale-8 (MMAS-8). RESULTS: The mean age of the participants was 44.9 ± 6.5 years, and the mean duration of tamoxifen use was 834.4 ± 685.7 days. The women's mean MMAS-8 score was 6.86 ± 1.39. Medication adherence was significantly positively correlated with current age (p = 0.006) and age at diagnosis (p = 0.002). There was a statistically significant difference between tamoxifen adherence according to participants' employment status (p = 0.028), chronic disease status (p = 0.018), loss of libido (p = 0.012), treatment-related changes in mood changes (p = 0.004), and having negative effects affecting daily life (p < 0.001). CONCLUSION: Overall, breast cancer survivors in this study reported moderate adherence to tamoxifen. The women's individual characteristics and the adverse effects of treatment influenced medication adherence. Healthcare professionals can help increase adherence to this treatment, which reduces the risk of mortality, by explaining the importance of the medication, identifying and eliminating barriers to adherence, and informing women about evidence-based interventions to increase medication compliance.

Favorable locoregional control in clinically node-negative hormone-receptor positive breast cancer with low 21-gene recurrence scores: a single-institution study with 10-year follow-up.

BACKGROUND: Recent studies have shown a lower likelihood of locoregional recurrences in patients with a low 21-gene recurrence score (RS). In this single-institution study, we investigated whether there are any associations between different cutoff values of 21-gene RS, histopathological factors, and outcome in patients with long-term follow-up. METHODS: The study included 61 patients who had early-stage (I-II) clinically node-negative hormone receptor-positive and HER2-negative breast cancer and were tested with the 21-gene RS assay between February 2010 and February 2013. Demographic, clinicopathological, treatment, and outcome characteristics were analyzed. RESULTS: The median age was 48 years (range, 29-72 years). Patients with high histologic grade (HG), Ki-67 ≥ 25%, or Ki-67 ≥ 30% were more likely to have intermediate/high RS (≥ 18). Based on the 21-gene RS assay, only 19 patients (31%) received adjuvant chemotherapy. At a median follow-up of 112 months, 3 patients developed locoregional recurrences (4.9%), which were treated with endocrine therapy alone. Among patients treated with endocrine treatment alone (n = 42), the following clinicopathological characteristics were not found to be significantly associated with 10-year locoregional recurrence free survival (LRRFS): age < 40 years, age < 50 years, high histological or nuclear grade, high Ki-67-scores (≥ 15%, ≥ 20%, ≥ 25%, ≥ 30%), presence of lymphovascular invasion, luminal-A type, multifocality, lymph node positivity, tumor size more than 2 cm, RS ≥ 18, and RS > 11. However, patients with RS ≥ 16 had significantly poorer 10-year LRRFS compared to those with RS < 16 (75% vs. 100%, respectively; p = 0.039). CONCLUSIONS: The results suggest that patients with clinically node-negative disease and RS ≥ 16 are more likely to benefit from adjuvant chemotherapies. However, those with RS < 16 have an excellent outcome and local control in long-term follow-up with endocrine treatment alone.

Detachment and embolization of totally implantable central venous access devices: diagnosis and management.

BACKGROUND: Detachment and embolization (DE) is a rare complication of totally implantable central venous access devices (TIVADs). This study aimed to analyze clinical findings, etiology, and treatment options in DE of TIVADs. METHODS: Patients who experienced DE between 2010-2019 were included. Indications, implantation techniques, time to diagnosis, patient complaints, diagnostic methods, rupture site, location of embolization, treatment methods, and chest X-rays prior to detachment were analyzed retrospectively. RESULTS: DE of TIVAD was detected in 12(1.2%) patients. Eleven patients had breast cancer and one had colon cancer. Mean age at implantation was 45.3 ± 9.6(31-61.3) years. Seven (58%) patients were asymptomatic, four (33.3%) had TIVAD malfunction, and one (8.3%) had pain and swelling at port site after injection. Mean time from implantation to diagnosis was 1149.92(16-2795) days. The etiologies comprised Pinch-off Syndrome (POS) in eight (66%) patients, detachment directly adjacent to the lock mechanism in three (25%) patients, and probable iatrogenic injury during explantation in one (9%) patient. The most common site of embolism was the superior vena cava (25%). While the embolized fragment was removed percutaneously in 11 patients, medical follow-up was treatment choice for one patient. CONCLUSIONS: DE is a rare complication with an incidence rate of 1.2% in this study. Since most patients were asymptomatic, chest radiography plays an important role in diagnosis. The most common cause was POS, and it can be prevented by inserting the catheter from lateral third of the clavicle during subclavian vein catheterization. The first-choice treatment was percutaneous femoral retrieval. However, if not technically possible, alternative treatment options are thoracotomy or follow-up with anticoagulant therapy.

The Effect of Primary Surgery in Patients with De Novo Stage IV Breast Cancer with Bone Metastasis Only (Protocol BOMET MF 14-01): A Multi-Center, Prospective Registry Study.

BACKGROUND: More evidence shows that primary surgery for de novo metastatic breast cancer (BC) prolongs overall survival (OS) in selected cases. The aim of this study was to evaluate the role of locoregional treatment (LRT) in BC patients with de novo stage IV bone only metastasis (BOM). METHODS: The prospective, multicenter registry study BOMET MF14-01 was initiated in May 2014. Patients with de novo stage IV BOM BC were divided into two groups: those receiving systemic treatment (ST group) and those receiving LRT (LRT group). Patients who received LRT were further divided into two groups: ST after LRT (LRT + ST group) and ST before LRT (ST + LRT group). RESULTS: We included 505 patients in this study; 240 (47.5%) patients in the ST group and 265 (52.5%) in the LRT group. One hundred and thirteen patients (26.3%) died in the 34-month median follow-up, 85 (35.4%) in the ST group and 28 (10.5%) in LRT group. Local progression was observed in 39 (16.2%) of the patients in the ST group and 18 (6.7%) in the LRT group (p = 0.001). Hazard of death was 60% lower in the LRT group compared with the ST group (HR 0.40, 95% CI 0.30-0.54, p < 0.0001). CONCLUSION: In this prospectively maintained registry study, we found that LRT prolonged survival and decreased locoregional recurrence in the median 3-year follow-up. Timing of primary breast surgery either at diagnosis or after ST provided a survival benefit similar to ST alone in de novo stage IV BOM BC patients.

The role of loco-regional treatment in long-term quality of life in de novo stage IV breast cancer patients: protocol MF07-01Q.

BACKGROUND/OBJECTIVE: Since more solid evidence has emerged supporting the effectiveness of loco-regional treatment (LRT), clinicians consider LRT a treatment option for selected de novo stage IV breast cancer (BC) patients. This is the first report on long-term quality of life (QoL) in a cohort of patients who were randomized to receive either LRT and then systemic treatment (ST) or ST alone in the protocol MF07-01. We aimed to evaluate QoL in patients living at least 3 years since randomization using scores from the SF-12 health survey. METHODS: SF-12 (V2) forms were completed during visits of patients who were living 36 months after the randomization. We first calculated PCS-12 (Physical Health Composite Scale) and MCS-12 (Mental Health Composite Scale) scores from de novo stage IV BC patients and compared them with the scores of patients diagnosed with stage I-III BC who lived more than 3 years. Further, PCS-12 and MCS-12 scores were compared between the LRT and ST groups with de novo stage IV BC. Additionally, general health, physical functioning, role functioning, bodily pain, vitality, mental health, and social functioning were evaluated and compared between the groups. Considering age-related changes in QoL, we also compared PCS-12 and MCS-12 scores of patients below or above 55 and 65 years of age. Responses to four additional questions (compare your physical health, mental health, daily activities, and energy currently vs. at diagnosis of BC) were recorded, considering cultural differences. RESULTS: There were 81 patients in this analysis; 68% of patients (n = 55) had LRT, and 32% (n = 26) received ST. General health was good or very good in 62% (n = 34) in the LRT group and 66% (n = 17) in the ST-only group (p = 0.63). Mean PCS-12 score was 40.8 + 1.6, and mean MCS-12 score was 43.4 + 2.0 (p = 0.34 and p = 0.54, respectively). PCS-12 and MCS-12 score difference was lower than that of the general Turkish population (PCS-12 = 49.3 + 12.8 and MCS-12 = 46.8 + 13.0) and stage I-III BC patients (PCS-12 = 51.1 ± 0.5, MCS-12 = 45.7 ± 0.6). PCS-12 and MCS-12 scores were similar between the LRT and ST-only groups in patients younger and older than 55 and 65, but QoL scores were much better in stage I-III BC patients younger than 65 when compared to the scores of those with de novo stage IV BC. Although treatment with or without LRT did not affect physical health, mental health, daily activities, and energy at 3 years vs. at diagnosis of BC in de novo stage IV BC patients (p > 0.05), these variables were significantly better in stage I-III BC patients (p < 0.001). CONCLUSION: The current MF07-01Q study demonstrates that patient who had LRT has similar physical and mental health outcomes compared to ST only in a cohort of patients who lived longer than 3 years. Trial registration This study is registered on clinicaltrials.gov with identifier number NCT00557986.

Nipple-Sparing Mastectomy and Immediate Implant-Based Reconstruction with or Without Skin Reduction in Patients with Large Ptotic Breasts: A Case-Matched Analysis.

BACKGROUND: Nipple-sparing mastectomy (NSM) and implant-based immediate breast reconstruction are becoming preferred options with improved outcomes. However, reconstruction in patients with large and ptotic breasts is challenging. When mastectomy and skin reduction are combined in a single-staged procedure, the vasculature of the skin is disturbed leading to increased complication rates. This paper aims to compare complication rates of NSM and immediate implant-based reconstruction with or without reduction to determine the safety of reduction in this patient group. METHODS: Breast cancer patients that underwent NSM and implant-based immediate breast reconstruction between November 2010 and 2018 were analyzed. All implants were placed submuscularly. Patients with skin reduction and nipple-areolar complex transposition were matched in a 1:1 fashion with patients without reduction. RESULTS: There were 50 patients (72 procedures) in each group. Demographics of the groups were similar as a part of matching process. Mean implant volume in the reduction group was higher (399.93 ± 97.54 vs. 360.21 ± 82.54, p = 0.009). Full thickness skin necrosis rate was higher in the reduction group [12/72 (%17) vs. 2/72 (3%), p = 0.009], and the most common site was over the suture line [6/12 (50%)]. Complications in the reduction group were more common in reconstructions with implant volumes greater than 500 cc (p = 0.008). CONCLUSIONS: When compared with no reduction, the skin necrosis rate of NSM and immediate implant-based reconstruction with skin reduction is higher. The described technique can only be considered in patients with moderate breast volumes, grade II-III ptosis, and when the planned implant volume is low (< 500 cc). LEVEL OF EVIDENCE: IV.

Clinical Factors Affecting the Therapeutic Efficacy of Evening Primrose Oil on Mastalgia.

BACKGROUND: Saturated fatty acid esters may cause mastalgia via hypersensitivity of breast epithelium to circulating hormones. Evening primrose oil (EPO) may restore the saturated/unsaturated fatty acid balance and decrease sensitivity to steroidal hormones or prolactin. Conflicting results exist regarding EPO treatment for mastalgia. The aim of this study was to determine the effectiveness of EPO and factors affecting its efficacy in treatment of mastalgia. METHODS: The study included 1015 patients, ages 14-82 (mean age 42.21 ± 10.8), admitted to Acibadem Breast Clinic between January 2015 and March 2018. The patients were divided into group I (n = 581) treated with EPO (1300 mg, twice a day) and group II (n = 434) treated with paracetamol (500 mg, twice a day). The visual analog scale was used to assess EPO's therapeutic efficacy, compared with paracetamol, measured at admittance, 2 weeks, and 6 weeks. Clinical factors affecting the efficacy of EPO were analyzed. RESULTS: The therapeutic efficacy of EPO on mastalgia was significantly higher than with paracetamol (p < 0.001). Factors significantly affecting the efficacy of EPO treatment were hormone replacement therapy (HRT), IUD-with-levonorgestrel, iron deficiency, overt hypothyroidism, and Hashimoto thyroiditis (p < 0.01). Replacement of iron or thyroid hormone efficiently treated mastalgia in patients that did not respond to EPO treatment. Side effects (allergy, anxiety, blurred vision, constipation, and nausea) were rare and not statistically significant (p = 0.88). CONCLUSION: EPO can be used in the treatment of mastalgia without significant side effects. HRT, IUD-with-levonorgestrel, iron deficiency, overt hypothyroidism, and Hashimoto thyroiditis significantly affect the efficacy of EPO on mastalgia.

Comparison of automated versus hand-held breast US in supplemental screening in asymptomatic women with dense breasts: is there a difference regarding woman preference, lesion detection and lesion characterization?

PURPOSE: To compare automated breast volumetric scanning (ABVS) with hand-held bilateral whole breast ultrasound (HHUS) prospectively in regards to patient workflow, woman preference, efficacy in lesion detection, and characterization. MATERIALS AND METHODS: Supplemental screening was performed with both ABVS and HHUS to 345 women with dense breasts and negative mammograms. Acquisition and evaluation times were recorded. Lesions were classified according to BIRADS US criteria and compared one to one. Women were recalled for a secondary HHUS examination if ABVS showed any additional lesions. Findings were compared based on biopsy results and/or 36-48 months of follow-up. RESULTS: Findings could be compared for 340 women. There were two carcinomas which were detected by both methods, with no interval cancers in the follow-up period. Recall rate was 46/340 (13.05%) for ABVS and 4/340 (1.18%) for HHUS. ABVS recalls decreased with experience. HHUS had more true negative (BIRADS 1-2) results, while ABVS had more false positive ones (p < 0.001). Positive predictive value was 4.17% for ABVS and 50% for HHUS. ABVS overdiagnosed shadowings (p < 0.01), distortions (p < 0.034), and irregular nodules (p < 0.001) in comparison to HHUS. At ABVS, 10.6% of women experienced severe pain. 59.7% stated that they would choose HHUS if they had the chance. CONCLUSION: ABVS is as good as HHUS in lesion detection. However, the recall rate is higher and positive predictive value is lower with ABVS, which could result in more follow-ups, and more anxiety for the women. More than 50% women stated they would prefer HHUS if they were given the chance.

Oncologic safety of nipple-sparing mastectomy in patients with short tumor-nipple distance.

BACKGROUND: There is a tendency to avoid nipple-sparing mastectomy (NSM) when a tumor-nipple distance (TND) is <2 cm due to the risk of occult nipple involvement. The purpose of the study was to determine whether the patients who undergo NSM with immediate reconstruction are oncologically safe when TND is <2 cm. METHODS: Patients who underwent NSM followed by immediate reconstruction for breast cancer were retrospectively analyzed. Patients who are negative for nipple-base in either frozen-section or paraffin histopathology were included. MRI was used to obtain TNDs to compare local-recurrence-free and disease-free survival in group I (TND <2 cm) and group II (TND ≥2 cm). Disease-free survival rates were determined to assess the outcome. RESULTS: Of the 214 cases with malignancy on MRI, 21 cases diagnosed with pure ductal carcinoma in situ were excluded. Among the 193 NSM cases diagnosed with invasive cancer, TND was <2.0 cm in 59 (30.56%) cases and ≥2.0 cm in 134 (69.43%) cases. No significant differences were found between groups in regards to ER, PR, HER2-neu status, and nodal involvement (P = 0.34, P = 0.41, P = 0.54, and P = 0.12 respectively). In a median follow-up time of 62 months (range; 13-114), patients in group I had four local recurrences, whereas group II was found to have five local and three distant metastases. No significant differences were observed between groups concerning disease-free survival (10-year DFS 93.2% vs 96.3%; P = 0.368 respectively). CONCLUSIONS: Patients who have invasive cancer diagnosis with a TND <2 cm are eligible to undergo therapeutic NSM with immediate reconstruction.

Factors Associated With Complications in Immediate Breast Reconstruction in 1 Stage With Completely Submuscular Implants.

BACKGROUND: Immediate breast reconstruction in 1 stage using permanent implants is gaining popularity and can be performed with or without the use of acellular dermal matrices. This study aimed to investigate the results of breast implants placed submuscularly without acellular dermal matrix and assess the factors affecting surgical complications. METHODS: From November 2009 to March 2018, 138 patients underwent immediate breast reconstruction with permanent submuscular implants after concomitant skin-sparing or nipple-sparing mastectomies in a single institution. All implants were covered with sufficient soft tissue under a submuscular pocket. RESULTS: One hundred thirty-eight patients were enrolled, and a total of 196 breasts were operated. The average age and body mass index (BMI) of the patients were 44.9 ± 8.8 years and 23.7 ± 3.6 kg/m, respectively. The majority of the mastectomies were therapeutic (81%). The average volume of implants was 389 ± 89 mL, and the mean follow-up was 33 months. The overall complication rate was 17% (n = 23), with skin necrosis being the most common complication followed by infections. Having a BMI equal to or greater than 25 kg/m was found to be a statistically significant predictor for overall complications (P = 0.002), whereas smoking history, age, and implant volume were not statistically significant. CONCLUSIONS: Immediate breast reconstruction in 1 stage using permanent implants can be performed with acceptable complication rates and cosmetic outcomes. Our study demonstrated that high BMI is a risk factor for overall complications. With proper patient selection and surgical technique, implants could be completely covered under a submuscular pocket.

Randomized Trial Comparing Resection of Primary Tumor with No Surgery in Stage IV Breast Cancer at Presentation: Protocol MF07-01.

BACKGROUND: The MF07-01 trial is a multicenter, phase III, randomized, controlled study comparing locoregional treatment (LRT) followed by systemic therapy (ST) with ST alone for treatment-naïve stage IV breast cancer (BC) patients. METHODS: At initial diagnosis, patients were randomized 1:1 to either the LRT or ST group. All the patients were given ST either immediately after randomization or after surgical resection of the intact primary tumor. RESULTS: The trial enrolled 274 patients: 138 in the LRT group and 136 in the ST group. Hazard of death was 34% lower in the LRT group than in the ST group (hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.49-0.88; p = 0.005). Unplanned subgroup analyses showed that the risk of death was statistically lower in the LRT group than in the ST group with respect to estrogen receptor (ER)/progesterone receptor (PR)(+) (HR 0.64; 95% CI 0.46-0.91; p = 0.01), human epidermal growth factor 2 (HER2)/neu(-) (HR 0.64; 95% CI 0.45-0.91; p = 0.01), patients younger than 55 years (HR 0.57; 95% CI 0.38-0.86; p = 0.007), and patients with solitary bone-only metastases (HR 0.47; 95% CI 0.23-0.98; p = 0.04). CONCLUSION: In the current trial, improvement in 36-month survival was not observed with upfront surgery for stage IV breast cancer patients. However, a longer follow-up study (median, 40 months) showed statistically significant improvement in median survival. When locoregional treatment in de novo stage IV BC is discussed with the patient as an option, practitioners must consider age, performance status, comorbidities, tumor type, and metastatic disease burden.

A Simple Flap Design for the Salvage of Immediate Implant-Based Breast Reconstruction.

BACKGROUND: Breast reconstruction with implants is a real challenge in patients with large breast volume. Skin-reducing inverted-T mastectomy is the best solution for these patients. Delayed wound healing or necrosis at the T-junction area can be seen in this procedure, although it may also lead to severe conditions such as the exposure and loss of implant. In this article, the use of local pedicled flap for the management of these situations was discussed. METHODS: Between April 2010 and July 2015, 54 patients underwent breast reconstruction by inverted-T skin-reducing mastectomy and immediate implant-based breast reconstruction at our clinic. During the postoperative follow-up period, necrosis at the T-junction area was observed in 8 patients. All the patients received proper wound care, and the necrosis was surgically debrided. The defect was closed with Limberg-like rectangular flap. RESULTS: The mean age was 45.2 (range, 33-54) years. The mean body mass index was 25.57 ± 6.53 (range, 21.2-35.2) kg/m. The mean follow-up was 10.9 (range, 4-19) months. Two patients had implant exposure at the defect site after the debridement. There was no implant loss in any of the patients. CONCLUSIONS: The Limberg-like rectangular flap can be used as a salvage option in complicated skin-reducing mastectomies and can be considered as a safe and effective method because of its easy-to-use nature, low cost, and no need for microsurgery experience.

Risk Factor Analysis for Survival of Becker-Type Expander in Immediate Breast Reconstruction.

BACKGROUND: Breast reconstruction with a Becker-type expander is a common technique following mastectomy. However, inconsistency remains in the literature regarding risk factors for the survival of a Becker-type expander following immediate breast reconstruction. This study's purpose is to investigate possible risk factors for the Becker-type expander survival and to evaluate the complications related to expander removal following immediate breast reconstruction. METHODS: We performed a retrospective chart review of consecutive women who underwent a mastectomy followed by immediate breast reconstruction with a Becker-type expander from November 2010 to November 2016. Electronic medical records were analyzed retrospectively for demographic, clinical, operative characteristics, and outcomes. Univariate Cox regression analysis was performed to determine the risk factors for the survival of the Becker-type expander following immediate breast reconstruction. RESULTS: A total of 74 Becker-type expanders were used in 72 patients who underwent immediate breast reconstruction. The patients' ages ranged from 27 to 71 years, with a mean ± standard deviation age of 44.6 ± 9.1 years. The most frequent complication was capsular contracture which occurred in 25 breasts (33.8%) followed by mastectomy skin flap necrosis in 6 breasts (8.1%), seroma in 4 breasts (5.4%), nipple-areolar complex necrosis in 4 breasts (5.4%), hematoma in 3 breasts (4.1%), and infection in 2 breasts (2.7%). The mean intraoperative expander fill volume (109.6 ± 66.9 cc [p = 0.039]) and mean total volume (386.5 ± 94.7 cc [p = 0.034]) were both significantly lower for patients with capsular contracture compared with those without capsular contracture. In patients with partial NAC necrosis, the mean mastectomy specimen volume (737.5 ± 242.8 cc) was significantly higher compared with patients without partial NAC necrosis (489.8 ± 219.0 cc; p = 0.027). A univariate Cox regression analysis showed that smoking and neoadjuvant therapy were significantly associated with expander removal (p = 0.023 and p = 0.006, respectively). CONCLUSION: The total volume of the expander and intraoperative fill volume of the expander appear to be predictive factors in the development of capsular contracture. However, there is no statistically significant association between radiotherapy and capsular contracture or expander survival in contrast with other published reports. Our findings reveal that the main risk factors for the survival of Becker-type expanders following immediate breast reconstruction are smoking and neoadjuvant therapy. To our knowledge, this is the first study to evaluate the most likely risk factors associated with Becker-type expander survival in immediate breast reconstruction.

Sentinel lymph node biopsy under fluorescent indocyanin green guidance: Initial experience.

OBJECTIVE: Sentinel lymph node biopsy can be applied by using either blue dye or radionuclide method or both in breast cancer. Fluorescent imaging with indocyanine green is a new defined method. This study evaluates the applicability of sentinel lymph node biopsy via fluorescent indocyanine green. MATERIAL AND METHODS: IC-VIEW (Pulsion Medical Systems AG, Munich, Germany) infrared visualization system was used for imaging. Two mL of indocyanine green was injected to visualize sentinel lymph nodes. After injection, subcutaneous lymphatics were traced and sentinel lymph nodes were found with simultaneous imaging. Sentinel lymph nodes were excised under fluorescent light guidance, and excised lymph nodes were examined histopathologically. Patients with sentinel lymph node metastases underwent axillary dissection. RESULTS: Four patients with sentinel lymph node biopsy due to breast cancer were included in the study. Sentinel lymph nodes were visualized with indocyanine green in all patients. The median number of excised sentinel lymph node was 2 (2-3). Two patients with lymph node metastasis underwent axillary dissection. No metastasis was detected in lymph nodes other than the sentinel nodes in patients with axillary dissection. There was no complication during and after the operation related to the method. CONCLUSION: According to our limited experience, sentinel lymph node biopsy under fluorescent indocyanine green guidance, which has an advantage of simultaneous visualization, is technically feasible.

HER2 Ile655Val and PTEN IVS4 polymorphisms in patients with breast cancer.

Although HER2/PTEN pathway is commonly disrupted in cancer, association of HER2 and PTEN polymorphisms with breast cancer (BC) remains controversial. We investigated the HER2 Ile655 Val and PTEN IVS4 polymorphisms in patients with BC in Turkish population. HER2 Ile655Val (rs 1136201) and PTEN IVS4 (rs 3830675) polymorphisms were determined using polymerase chain reaction-based restriction fragment length polymorphism (PCR-RFLP) in blood samples of 118 BC patients and 118 age-matched healthy controls. We found that the frequency of the Ile/Val genotype of HER2 Ile655Val gene was significantly higher in BC patients (p < 0.009; OR: 1,983 95 % CI: 1.181-3.328). The presence of ATCTT insertion (+/+) genotype at downstream of exon 4 in intron 4 of PTEN IVS4 gene was also associated with 1.83 fold decreased risk of BC development (p < 0.033; OR: 1.83, 95 % CI: 1.11-3.03). Analysis on clinico-pathological parameters showed neither HER2 Ile655Val nor PTEN IVS4 genotypes were not associated with any of the variables (p > 0.05).In conclusion, our findings suggest that the Ile/Val genotype of HER2 and ATCTT insertion (+/+) genotype of PTEN IVS4 gene may play an important role as genetic markers for breast cancer risk, but both genes genotypes may not be useful for predicting tumor prognosis in Turkish population.

Sentinel lymph node biopsy after nipple-sparing mastectomy in early postoperative period: Is it feasible?

Background: Axillary lymph node status is one of the most important prognostic factors for breast cancer. Sentinel lymph node biopsy (SLNB) after mastectomy is highly controversial. There is not enough data about SLNB in the early period after nipple-sparing mastectomy (NSM). This study investigated the feasibility of SLNB in the early postoperative period of NSM. Materials and Methods: Patients who were operated on for breast cancer in Acibadem Maslak Hospital between 2009 and 2018 were searched retrospectively. Results of SLNB as the second session in patients whose final pathology report revealed breast carcinoma after contralateral/bilateral prophylactic mastectomy and mastectomy for benign lesions were evaluated. Results: In the early period (median 14 days) after NSM, SLNB was performed by intradermal radioisotope injection in five patients with occult breast cancer in contralateral/bilateral prophylactic mastectomy and in one patient with preoperatively suspicious mass which yielded breast cancer at final pathology. In five (80%) patients, SLNB was performed, whereas in one patient axillary lymph node dissection (ALND) was performed due to the undetectability of SLN. In one patient, micrometastasis was observed, whereas no metastasis was observed in other patients including the one who underwent ALND. No complication due to SLNB was detected. No recurrence and distant metastasis were detected in a mean follow-up of 42.82 (19-70) months. While SLNB did not change the treatment of patients with contralateral occult carcinoma, other patients had hormonal therapy due to negative SLNB. Conclusion: SLNB in the early postoperative period of NSM can be performed by intradermal radioisotope injection. However, further studies are needed to determine the feasibility of SLNB in the early postoperative period of NSM.

Implant selection in natural and stable direct-to-implant reconstruction with ten steps at nipple-sparing mastectomy.

Direct-to-implant reconstruction is one of the breast repair techniques after mastectomy. Implant selection is critical in the short- and long-term success of direct-to-implant reconstruction after nipple-sparing mastectomy. In this study we developed a 10-step algorithm that we use before and during surgery. We aimed to obtain natural and stable breast reconstruction with this algorithm. In addition, we also aimed to evaluate which implants were selected using this algorithm and their short- and long-term outcomes. This retrospective study included 218 patients aged 27 to 60 years who underwent mastectomy and direct-to-implant reconstruction between November 2018 and December 2021. The patients were assigned into 4 groups according to amount of breast tissue removed. We developed a 10-step algorithm and these included: breast base, amount of breast tissue removed, evaluation of mastectomy skin flap, breast projection, ptosis, unilateral/bilateral reconstruction, chest wall deformity, patient's request, comorbid conditions and stabilization and arrangement of novel sulcus. The evaluation was made when the patient's photographs were taken at least 1 year after the surgery. The highest number of patients was recorded in group 3; in addition, mean age was also highest in group 3. The lowest number of patients was recorded in group 4. The body mass index showed a progressive increase from group 1 to group 4. Medium height moderate profile prosthesis was used in 81.7% while medium height moderate plus profile prosthesis was used in 18.3% of breasts included. We used larger prosthesis up to 58.1% when compared to the tissue removed in group 1 while we used smaller prosthesis by 25.6% in group 4. In the anterior view, the medial and lateral arch of the lower pole of the breast was obtained in all patients. Obvious asymmetry developed in 4 patients. In lateral and oblique views, upper and lower pole natural breast images were obtained in all patients, except for 5 patients. There was no sulcus inferior displacement in any patient. Implant extrusion did not occur in any patient. This algorithm is an easy to use and effective method to obtain a stable and natural breast image in the long-term.
