Breast hematoma with active bleeding due to seat belt injury.

Breast emergencies are not frequent but play an important part in routine breast imaging applications. Diagnosis and identification of seat belt injury in emergency department are essential for patient management and early treatment of advanced cases. Herein we reported imaging findings of a patient who had prominent swollen at her left breast accompanying tissue edema and painful palpable mass formed by active bleeding hematoma as a result of seat belt injury due to a car accident. Radiologic examinations revealed hematoma in the breast accompanying active bleeding.

Does the variant positivity and negativity affect the clinical course in COVID-19?: A cohort study.

The primary aim of the current study is to analyze the clinical, laboratory, and demographic data comparing the patients with Coronavirus Disease 2019 (COVID-19) admitted to our intensive care unit before and after the UK variant was first diagnosed in December 2020. The secondary objective was to describe a treatment approach for COVID-19. Between Mar 12, 2020, and Jun 22, 2021, 159 patients with COVID-19 were allocated into 2 groups: the variant negative group (77 patients before December 2020) and the variant positive group (82 patients after December 2020). The statistical analyses included early and late complications, demographic data, symptoms, comorbidities, intubation and mortality rates, and treatment options. Regarding early complications, unilateral pneumonia was more common in the variant (-) group (P = .019), whereas bilateral pneumonia was more common in the variant (+) group (P < .001). Regarding late complications, only cytomegalovirus pneumonia was observed more frequently in the variant (-) group (P = .023), whereas secondary gram (+) infection, pulmonary fibrosis (P = .048), acute respiratory distress syndrome (ARDS) (P = .017), and septic shock (P = .051) were more common in the variant (+) group. The therapeutic approach showed significant differences in the second group such as plasma exchange and extracorporeal membrane oxygenation which is more commonly used in the variant (+) group. Although mortality and intubation rates did not differ between the groups, severe challenging early and late complications were observed mainly in the variant (+) group, necessitating invasive treatment options. We hope that our data from the pandemic will shed light on this field. Regarding the COVID-19 pandemic, it is clear that there is much to be done to deal with future pandemics.

Machine Learning-Based Ultrasound Texture Analysis in Differentiation of Benign Phyllodes Tumors from Borderline-Malignant Phyllodes Tumors.

PURPOSE: Phyllodes tumors (PTs) are uncommon fibroepithelial breast lesions that are classified as three different forms as benign phyllodes tumor (BPT), borderline phyllodes tumor (BoPT), and malignant phyllodes tumor (MPT). Conventional radiologic methods make only a limited contribution to exact diagnosis, and texture analysis data increase the diagnostic performance. In this study, we aimed to evaluate the contribution of texture analysis of US images (TAUI) of PTs in order to discriminate between BPTs and BoPTs-MPTs. METHODS: The number of patients was 63 (41 BPTs, 12 BoPTs, and 10 MPTs). Patients were divided into two groups (Group 1-BPT, Group 2-BoPT/MPT). TAUI with LIFEx software was performed retrospectively. An independent machine learning approach, MATLAB R2020a (Math- Works, Natick, Massachusetts) was used with the dataset with p < 0.004. Two machine learning approaches were used to build prediction models for differentiating between Group 1 and Group 2. Receiver operating characteristics (ROC) curve analyses were performed to evaluate the diagnostic performance of statistically significant texture data between phyllodes subgroups. RESULTS: In TAUI, 10 statistically significant second order texture values were identified as significant factors capable of differentiating among the two groups (p < 0.05). Both of the models of our dataset make a diagnostic contribution to the discrimination between BopTs-MPTs and BPTs. CONCLUSION: In PTs, US is the main diagnostic method. Adding machine learning-based TAUI to conventional US findings can provide optimal diagnosis, thereby helping to choose the correct surgical method. Consequently, decreased local recurrence rates can be achieved.

High riding jugular bulb: prevalence and significance in asymptomatic children.

BACKGROUND: High riding jugular bulb (HJB) is a vascular abnormality characterized by the higher-than-normal location of the jugular bulb. PURPOSE: To evaluate the frequency of HJB among children who underwent cranial computed tomography (CT) mostly because of head trauma. MATERIAL AND METHODS: Patient demographics such as age, sex, indication of cranial CT, diameters of the right and left JB, and presence and laterality of HJB were recorded and analyzed. Patients were grouped as with HJB and without HJB; the variables were compared between these two groups. Patients were also divided into age groups as 0-1 month, 1-12 months, 12-24 months, and >24 months and the findings. The Shapiro-Wilk test, histograms, and Q-Q, Mann-Whitney U-test, Pearson's chi-square test, and Fisher's exact test were used. RESULTS: In total, CT images of 194 patients (388 JBs) were evaluated. Overall, 42.8% of children had HJB. Only three children had bilateral HJB. Of all JBs, 22.2% were high riding. Children who did not have HJB were significantly younger compared to children with HJB (P = 0.029). The median diameter of the HJB was significantly higher in children with HJB compared to children without HJB on both sides (P < 0.001). Among newborns, none had HJB. In infants, 11 (30.6%) had HJB; 35 (46.7%) and 37 (50.0%) children aged >12-24 months and >24 months had HJB, respectively. CONCLUSION: A jugular bulb could be identified in all age groups, including newborns. The earliest age of HJB detection was eight months. Overall, 42% of the patients had HJB, which increased by age.

A case of a high-flow priapism treated with superselective transcatheter embolization.

High-flow priapism is a rare condition characterized by prolonged and painless erection. It is defined as contusion or thrombosis of the cavernous body of the penis usually secondary to blunt trauma. Due to the rarity of the disease, there is no well-defined consensus about treatment. Conservative treatment is often applied with non-steroidal anti-inflammatory drug. We present a case of 58-year-old man with proximal partial priapism that developed secondary to blunt trauma to the penis. The patient did not benefit from non-steroidal anti-inflammatory drug therapy and then was successfully treated with selective embolization.

Sonoelastography findings of myofibroblastoma.

Myofibrolastoma of the breast (MFB) is a rare and benign stromal tumor. Although MFB is a benign entity, in radiologic evaluation, there is no specific diagnostic feature. Conventional breast imaging findings have been published before. Sonoelastography has been used as an imaging method that allows us to evaluate tissue stiffness in vivo and increases the specificity of B-mode ultrasonography in the discrimination of benign-malignant lesions. In this case report, it was shown that MFB is of high stiffness in shear wave elastography (SWE) evaluation. SWE findings of MFB, which is a benign lesion, have been described for the first time in the literature.

Could "Retrograde Intrarenal Surgery" be Used as an Efficient Technique in the Treatment of Calyceal Diverticula Stones.

OBJECTIVE: To evaluate the efficacy of retrograde intrarenal surgery (RIRS) and holmium laser lithotripsy in the treatment of symptomatic renal calyceal diverticular (CD) stones. STUDY DESIGN: A case series. PLACE AND DURATION OF STUDY: Department of Urology, Hisar Intercontinental Hospital, from 2008 and 2019. METHODOLOGY: Patients who underwent holmium laser lithotripsy with RIRS to manage symptomatic CD stones were evaluated retrospectively. Demographics, stone size, operation and hospital stay duration, the success of treatment and complications were noted. RESULT: Among the 30 treated patients, 13 patients were female and 17 were male. The mean age was 45.4 ± 11.9 (26-64), the stone diameter was 14.4 ± 4.1 mm, operation time was 70.47±35.7 (35-155) minutes, and mean length of hospital stay was 1.27±0.5 (1-3) days. In those patients who underwent RIRS, 26 (86.7%) were successfully treated while in 4 of 30 patients (13.3%) the procedure was not successful. Complications were observed in 10 (33.3%) patients. Clavien-I complications were demonstrated in 6 patients, Clavien III complications were demonstrated in 3 patients. One patient had urosepsis, 2 patients had ureteral laceration, and one patient with Clavien IV complication had perirenal hematoma. CONCLUSION: Laser lithotripsy therapy with RIRS is a safe and effective treatment for symptomatic calyceal diverticular stones and can be offered as the first-line treatment for calyceal diverticular stones. KEY WORDS: Calyceal diverticula, Stone disease, Flexible ureterorenoscopy, Holmium laser, RIRS.

Urachal Actinomycosis Presenting with Recurrent Urinary Tract Infections in a Middle-aged Woman: A Rare Case Report.

The urachal cyst, a remnant of allantois sac during embryogenesis, is a rare condition in adulthood. Urachus is an embryologic remnant degenerating after birth. Abberrant obliteration of the urachus causes urachal abnormalities. The urachal cysts are almost always symptomatic when infected. The symptoms include fever, abdominal pain, tenderness, lower abdominal mass, nausea, vomiting, and dysuria. Ultrasonography, computerised tomography, and magnetic resonance imaging techniques may be insufficient for diagnosis. In most cases, staphylococcus species are isolated from cultures of urachal cysts. Other microorganisms such as Escherichia coli, Enterococcus faecium, Klebsiella pneumonia, and rarely actinomyces may be isolated. Actinomyces, an anaerobic gram-positive filamentous bacterium, is a rare cause of granulomatous disease. In this case report, a 56-year woman with urachal cyst infection with actinomyces is discussed according to current knowledge. Key Words: Urachal cyst, Urachus, Chronic cystitis, Actinomyces.

The effects of stone density on surgical outcomes of retrograde intrarenal stone surgery.

OBJECTIVE: Several pre-operative parameters have been studied to estimate stone-free rate (SFR) following retrograde intrarenal surgery (RIRS) procedures. The objective of this study was to evaluate the effects of stone density on surgical outcomes of RIRS. METHODS: This retrospective study included 30 stone-free patients (Group SF) and 30 patients with residual fragments (Group RF). Patients' age and gender, laterality, non-contrast CT findings, including size and density of the kidney stones, infundibular pelvic angle (IPA), operational time, and post-operative pain were recorded and compared between the two groups. The stone density was measured by free hand region of interest (ROI) determination coincident with the stone borders and expressed as Hounsfield units (HUs). RESULTS: The rate of single stones was significantly higher in Group SF compared to Group RF (p < 0.001). The mean stone size was found as 11.93 ± 7.81 mm in Group SF and 16.27 ± 7.29 mm in Group RF with the difference being statistically significant (p < 0.001). The mean IPA was 53.87 degrees in Group SF and 50.33 degrees in Group RF. The mean density was measured as 748.17 ± 318.14 HU in Group SF and 945.90 ± 345.30 HU in Group RF. The mean stone density was statistically significantly higher in patients with residual fragments compared to the stone-free patients (p < 0.001). CONCLUSION: This study revealed that stone density as measured as HU affects the treatment outcomes with RIRS procedure and the mean density is significantly higher in patients with residual stone fragments. ADVANCES IN KNOWLEDGE: Studies about the effects of HUs on stone-free rate are limited in the literature. Stone density affects the treatment outcomes with RIRS procedure and the mean density is significantly higher in patients with residual stone fragments.

Evaluation of hereditary/familial breast cancer patients with multigene targeted next generation sequencing panel and MLPA analysis in Turkey.

Breast cancer, a worldwide leading cause of cancer in women, may occur in familial cases. Germline mutations in BRCA1/2 genes are responsible for 15% of the familial cases. With the power of next generation sequencing (NGS) analysis, it is possible to analyze genes related to hereditary susceptibility to breast cancer and investigate the genetic etiology more thoroughly. In this study, we investigated 30 genes identified frequent pathogenic alleles in Turkish population. The study includes 495 unrelated individuals diagnosed with breast cancer who are selected for genetic testing according to NCCN criteria for hereditary breast cancer. All patients were analyzed by NGS for BRCA1/2 genes. Deletion/duplication investigation by Multiplex ligation-dependent probe amplification (MLPA) and massive sequencing of 30 breast cancer-related genes (Oncorisk Gene Panel) were performed in a stepwise manner. BRCA1/2 variants are the most frequent pathogenic variants which are found in 45 of 495 (9.1%) patients. Four previously unreported, novel, pathogenic variants of BRCA2 gene are identified. In four cases, exonic deletions of BRCA1/2 genes are determined and there is no duplication of these genes. NGS panel investigation involving other moderate-high risk genes contributed genetic diagnosis in an extra 39 out of 419 (9.3%) cases. Our study presents the cost effectiveness of the gene panel approach. We suggest that gene panels should be the first-tier genetic testing for hereditary breast cancer and MLPA analysis of BRCA1/2 genes should be investigated as a complementary method of NGS analysis.

The relationship between ultrasound-based TIRADS and BETHESDA categories in patients undergoing thyroid biopsy.

The TIRADS is a scoring system used for the selection of nodules for FNA and classification of the risk of malignancy based on ultrasound characteristics. The BETHESDA is a standard reporting system used for the classification of FNA results based on six criteria with risks for malignancy. The objective of this study was to evaluate the relationship between TIRADS and BSRTC classifications in patients undergoing thyroid biopsy. A total of 350 consecutive patients were retrospectively evaluated using TIRADS and BETHESDA reporting systems for determining preoperative diagnosis of thyroid nodules. Patients' demographics, size, echogenicity and contour status of the nodules, TIRADS and BETHESDA scores were recorded and analyzed. Data obtained in this study were expressed as mean, standard deviation, frequency and percentage descriptive statistics. The mean age of the patients was 49.03 ± 17.58 years. The mean nodule size was measured as 20.56 ± 10.47 mm. TIRADS TR3 category was found in 165 (47.14%), TR4 in 154 (44%) and TR5 in 31 (8.86%) patients, while BETHESDA II category was found in 288 (82.28%), BETHESDA III category in 1 (0.29%), BETHESDA IV category in 19 (5.43%), BETHESDA V in 37 (10.57%) and BETHESDA VI in 5 (1.43%) patients. There was a general concordance between BETHESDA and TRIADS categories. The most significant concordance was found between BETHESDA IV and TR4 categories (84.21%). Combined use of TRIADS and BETHESDA can be efficiently used to provide the most accurate results for making preoperative diagnosis of thyroid nodules and to determine the risk of malignancy.

Co-occurrence of vertebral artery hypoplasia and high jugular bulb in patients undergoing cranial magnetic resonance imaging.

We aimed to assess the frequency and coexistence of vertebral artery hypoplasia (VAH) and high jugular bulb (HJB) in subjects who underwent cranial magnetic resonance imaging (MRI) for diverse indications. This was a retrospective study in which 2184 consecutive patients who underwent cranial MRI were screened. Age, sex, and reasons for ordering cranial MRI were obtained from hospital database. Nineteen patients were excluded from the study. We defined VAH as a vertebral artery whose diameter was smaller than 2 mm with an asymmetry ratio of ≤ 1:1.7. HJB was defined as the jugular bulb lying higher than the inferior portion of the internal acoustic meatus. Pearson's χ2 test was used to study the association between VAH and HJB. A total of 2165 subjects were included in the final analysis. Median age was 34 years (min-max 1-98 years). Females constituted 51.4%. The most common complaint for which brain MRI was ordered was headache (68.5%), followed by vertigo (13%). VAH was present in 890 subjects (40.9%). The majority of the patients had unilateral VAH, mainly on the right side (72.9%). HJB was present in 1067 subjects (48.9%) and 24.9% of the temporal bones. HJB was three times more common on the right side than on the left (71.6%). Five-hundred and seventy-three (26.5%) had VAH and HJB concurrently. When a patient had either VAH or HJV, the likelihood of patient having the other condition was significant (p < 0.001). Binary logistic regression analysis showed that presence of VAH increased the probability of occurrence of HJB threefold and vice versa (p < 0.001, CI 2.502-3.574). This was the first report of significantly common co-occurrence of VAH and HJB.

Did COVID-19 area change our urology practice: A retrospective analysis.

OBJECTIVE: This research aimed at evaluating the changing conditions and experiences of urological practice during the COVID-19 pandemic. METHODS: The data of all patients who were admitted to outpatient clinics at Hisar Intercontinental Hospital or the hospital's online patient portal system between March 11th and May 30th, 2020 were analyzed retrospectively. Of all patients, 545 in outpatient clinics and 25 in online portal system, (17%) were hospitalized for medical treatment, and 53 underwent surgery. There were 1032 patients admitted to Urology Clinics and 104 patients who underwent surgery in the same period of 2019. The pre-operative assessment of patients who were candidates of urological surgery included certain criteria for COVID-19. RESULTS: Of patients included in this study, the median age was 41 years (18-90). The mean hospital stay was 1 day (1-12), and the mean duration of operation was 25 min (3-250). Thirty-seven patients (69.8%) underwent general anesthesia, while only 11(20.8%) underwent combined spinal epidural anesthesia. Four patients (7.5%) required local and only one patient (1.9%) underwent sedo-analgesia. Complications were encountered in six patients (11.4%), urosepsis in two, pneumonia in one, and urinary tract infection in three patients. Compared to last year's numbers, the number of patients admitted to the hospital's outpatient clinic and that of hospitalized patients decreased by 47.2% and 49.1%, respectively. CONCLUSION: Emergent surgeries in urological practices can be performed safely under routine preoperative testing for COVID-19 and with the use of adequate protective equipment for both the surgical team and the patient.

Predictive Factors for Unnecessary Axillary Dissection According to SLN Metastasis in T1, T2 Stage Breast Cancer.

The axillary nodes' status is essential in determining the treatment algorithm according to complete clinical staging. Unnecessary axillary lymph node dissection (ALND) has been prevented after sentinel lymph node biopsy (SLNB) has occurred in current practice. However, approximately half of patients with positive SLNB do not have axillary metastatic lymph nodes. Our study aims to predict unnecessary ALND in patients with SLN metastases by evaluating the patients' clinicopathological data. In total, 221 patients with macrometastasis in SLNB who underwent completion ALND were evaluated retrospectively. Patients were divided into two groups: patients with metastases only in the sentinel lymph node and additional axillary lymph nodes. Univariate and multivariate logistic regression analyses were used to analyze the correlation between SLN metastasis and axillary lymph node metastasis; clinicopathological characteristics, including patient age, menopause status, tumor size and grade, receptor status proliferative marker status, and molecular subtypes of the tumor. In the evaluation of T1-2, cN0 breast cancer patients with SLNB in the form of macrometastasis, only SLNB metastasis was found in 118 (53.4%) patients. In 103 (46.6%) patients, additional axillary node metastasis was observed. The risk of additional nodal spread correlated with patient age older than fertility age (age of 49) (p = 0.015, OR: 1.96, 95% CI: 1.14-3.39) and the number of increased metastatic sentinel nodes (p < 0.001). In line with the data shown by our study, the rate of axillary metastases increases in patients over the age of fertility and as the number of metastatic SLNs increases.

IONIZING RADIATION EXPOSURE IN PATIENTS WITH COVID-19: MORE THAN NEEDED.

OBJECTIVE: The aim of the study was to evaluate the ionizing radiation exposure in patients with Coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: This was a retrospective study in which all patients presented with suggestive symptoms of COVID-19 were included. The study was carried out in a university-affiliated private hospital in Istanbul, Turkey. Biological radiation dose exposure (cumulative effective dose: CED) was evaluated in millisievert (mSv) units. RESULTS: A total of 1410 patients were included in the study. Of all study subjects, 804 patients (57%) underwent only one chest computed tomography (CT) procedure. Six hundred and six patients (43%) had two or more chest CT procedures. Median CED was 6.02 (min-max:1.67-16.27) mSv. The number of patients who were exposed to ≤ 5 mSv were 149 (24.6%), whereas 457 patients (75.4%) were exposed to >5 mSv. CONCLUSION: The radiation exposure in COVID-19 patients seems unjustifiably high. Awareness should be increased as to the proper use of chest CT in COVID-19 as per to the society recommendations.

The relationship between lesion density change in chest computed tomography and clinical improvement in COVID-19 patients.

OBJECTIVE: To evaluate the association of changes in chest computed tomography (CT) lesion densities with clinical improvement in COVID-19 patients. METHODS: This was a cross-sectional analysis of hospitalised COVID-19 patients who underwent repeated chest CT. Patients who improved clinically but showed radiological progression were included. Demographic data, presentation complaints and laboratory results were retrieved from the electronic database of the hospital. Lesion density that was measured in Hounsfield units was compred between admission and discharge chest CT scans. RESULTS: Forty patients (21 males, mean age 47.4 ± 15.1 years) were included in the analysis. The median white blood cell count and C-reactive protein significantly decreased, whereas the median lymphocyte count significantly increased at discharge compared with the admission values. The mean density significantly reduced from admission to discharge. CONCLUSION: This is the first study in the literature reporting reduction in chest CT lesion densities correlated with clinical and laboratory improvement in COVID-19 patients.

Intra-operative parathyroid hormone evaluation is superior to frozen section analysis in parathyroid surgery.

BACKGROUND: Surgery is currently the only treatment option for patients with primary hyperparathyroidism (PHPT). Recently, minimally invasive parathyroidectomy (MIP) has begun to replace traditional bilateral neck exploration (BNE). OBJECTIVE: The aim of this study is to compare the results of parathyroidectomies performed in our hospital over the past decade that were guided by intra-operative parathyroid hormone (IOPTH) sampling or frozen section (FS) analysis. MATERIAL AND METHODS: Data on 697 patients who underwent parathyroidectomies in the Department of Endocrine Surgery, Dokuz Eylul University between January 2005 and 2018 were included in this study. Patients with malignancies other than thyroid papillary microcarcinoma and parathyroid cancer were excluded from the study. RESULTS: The concomitant use of neck ultrasound (US) and technetium 99m Sestamibi (99mTc MIBI) scintigraphy successfully localized the hyperfunctioning parathyroid glands in nearly 96% of cases. As compared with the IOPTH group, the operation time was longer in the FS group (p < 0.001), and the need for postoperative calcium (Ca) supplementation was higher (p < 0.001). The duration of hospitalization (days) was significantly higher in the FS group (4.2 ± 3.4 vs. 2.6 ± 1.9) as compared with that in the IOPTH group (p < 0.001). In addition, the recurrence rate in the FS group was significantly higher than that in the IPOTH group (p = 0.002). CONCLUSION: IOPTH sampling is a safe and effective method when performed by experienced surgeons and with appropriate preoperative screening. This study emphasizes that IOPTH sampling. We believe that the success in parathyroid surgery is due to three factors: correct indication, accurate localization and experienced surgeon.

Postmortem Biopsies of the Lung, Heart, Liver, and Spleen of COVID-19 Patients.

Objective We aimed to evaluate histopathologic alterations in the lung, heart, liver, and spleen of coronavirus disease 2019 (COVID-19) decedents through postmortem core needle biopsies. Materials and methods Patients who died of reverse transcription-polymerase chain reaction-proven COVID-19 were included in this postmortem case series. Postmortem percutaneous ultrasound-guided biopsies of the lungs, heart, liver, and spleen were performed using 14- and 16-gauge needles. Biopsy samples were stained with hematoxylin-eosin and examined under a light microscope. Clinicodemographic characteristics, chest computed tomography (CT) images, and COVID-19-related treatments of the patients were also collected. Results Seven patients were included in this study. Liver and heart tissue samples were available from all patients, and lung and spleen tissue samples were available from five and three patients, respectively. Chest CT images predominantly revealed bibasilar ground-glass opacities. Lung biopsies showed diffuse alveolar damage in all biopsy specimens. Heart findings were nonspecific and largely compatible with the underlying disease. Patchy necrosis, steatosis, and mononuclear cell infiltration were the main findings in the liver biopsies. Splenic histopathological examination showed that splenic necrosis and neutrophil infiltration were common findings in all patients. Conclusion Tissue acquisition was complete for the heart and liver and acceptable for the lungs. The amount of tissue was sufficient for a proper histopathologic examination. Histopathological findings were generally in accordance with previous autopsy studies. Radiological findings of the lung were also correlated with the histopathologic findings. We consider that a postmortem biopsy is a feasible alternative for histopathological examinations in COVID-19 decedents.

Shear-Wave Elastography-Guided Core Needle Biopsy for the Determination of Breast Cancer Molecular Subtype.

OBJECTIVE: To investigate whether shear-wave elastography (SWE) guidance during core-needle biopsy can improve diagnostic accuracy and accurate determination of the molecular subtypes of breast cancer. METHODS: This controlled, randomized prospective cohort study included 58 patients (mean age: 56.9 ± 16.2) who were referred for image-guided core-needle biopsy between May 2018 and April 2019 for lesions larger than 1 cm. In Group 1, 30 lesions were biopsied without SWE guidance and recorded as Biopsy A. In Group 2, 30 lesions were examined with SWE before biopsy, and then two different parts of the lesions were biopsied; biopsies from the relatively rigid areas of the lesions were recorded as Biopsy B, and biopsies from the less rigid areas of the lesions were recorded as Biopsy C. The histopathological and immunohistochemical results of biopsies were compared with the surgical results. RESULTS: The sensitivity of Biopsy A, B and C were 96.7%, 100% and 100%, respectively. The benign-malignant concordance rates were 94.7%, 100%, and 90% and the diagnostic concordance rates were 89.5%, 100%, and 90% in Biopsies A, B, and C, respectively. When the 10% differences in the estrogen receptor (ER), progesterone receptor (PR), and Ki67 rates were considered significant, the concordance rate of ER was highest in Biopsy B (77.8%; p = 0.040). The concordance rate of immunohistochemical subtyping was 100% in Biopsy B and 71.4% in Biopsies A and C (p = 0.086). CONCLUSION: SWE-guided core-needle biopsy of breast lesions increased the sensitivity, diagnostic accuracy, and accuracy of immunohistochemical subtyping to 100%.
