Does ARFI elastography complement B-mode ultrasonography in the radiological diagnosis of idiopathic granulomatous mastitis and invasive ductal carcinoma?

BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a chronic, unpleasant autoimmune inflammatory condition and is clinically and radiologically often confused with breast malignancy. PURPOSE: To investigate the contributions of qualitative and quantitative aspects of acoustic radiation force impulse (ARFI) elastography to the differential diagnosis between IGM and invasive ductal carcinoma (IDC) in the breast. MATERIAL AND METHODS: Ninety-four women with IDC and 39 with IGM were included in the study. Shear wave velocity (SWV) was calculated for all lesions using quantitative elastography. Next, each lesion's correspondence on qualitative elastographic images to those on the B-mode images was evaluated: pattern 1, no findings on elastography images; pattern 2, lesions that were bright inside; pattern 3, lesions that contained both bright and dark areas; and pattern 4, lesions that were dark inside. Pattern 4 was subdivided into 4a (dark area same size as lesion) and 4b (dark area larger than lesion size). Sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were calculated. RESULTS: The mean SWV based on ARFI elastography was 3.78 ± 1.26 m/s for IGM and 5.34 ± 1.43 m/s for IDC lesions (P < 0.05). Based on qualitative ARFI elastography, IDC lesions were mostly classified as pattern 4b, while IGM lesions were mostly classified as pattern 1 or 2 (P = 0.01). Evaluation of both the qualitative and quantitative aspects of ARFI elastography yielded a sensitivity of 89% and specificity of 84%. CONCLUSION: ARFI elastography may facilitate the differential diagnosis between IGM and IDC.

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.

Ultrasound Elastography for Distinction Between Parathyroid Adenomas and Thyroid Nodules.

OBJECTIVES: The aim of this study was to detect the level of stiffness of parathyroid adenomas and to distinguish them from benign and malignant thyroid nodules using ultrasound elastography with acoustic radiation force impulse imaging. METHODS: Twenty-one patients with parathyroid adenomas and 71 patients with thyroid nodules were evaluated by acoustic radiation force impulse imaging in this study. Acoustic radiation force impulse elastograms were obtained after evaluation of the thyroid nodules, which were predicted to undergo fine-needle aspiration biopsy, and patients with a diagnosis of hyperparathyroidism, which was identified by sonography at the same time. RESULTS: An analysis of mean shear wave velocity (SWV) values for parathyroid adenomas and thyroid nodules showed that parathyroid adenomas had significantly higher stiffness levels compared to benign thyroid nodules (mean SWV ± SD, 3.09 ± 0.75 versus 2.20 ± 0.39 m/s; P < .001) and lower stiffness levels compared to malignant thyroid nodules (mean SWV, 3.09 ± 0.75 versus 3.59 ± 0.43 m/s; P < .001). CONCLUSIONS: Acoustic radiation force impulse imaging has high sensitivity and specificity for differentiating parathyroid adenomas from benign and malignant thyroid nodules. As an adjunctive tool, it can help distinguish parathyroid adenomas from thyroid nodules, including posteriorly located nodules.

Intrahepatic splenosis after splenectomy performed for idiopathic thrombocytopenic purpura.

The term splenosis describes autotransplantation or implantation of ectopic splenic tissue within the abdominal cavity or in any other unusual body compartment. In addition to the diagnostic dilemma it causes, splenosis may also lead to persistence or recurrence of hematologic dysfunctions by its preserved immune activity especially in cases of splenectomy due to hematologic indications. Herein, we present a 40-year-old female who had splenectomy for idiopatic thrombocytopenic purpura, and was identified to have splenic tissue within left lobe of the liver during further assessment of ongoing thrombocytopenia.

Hepatic Artery Pseudoaneurysm: Delayed Presentation after a Blunt Trauma.

BACKGROUND: Ruptured hepatic artery pseudoaneurysm is a rare condition that is life-threatening if not diagnosed and treated rapidly. We present a case of a spontaneously ruptured hepatic artery pseudoaneurysm that occurred after a blunt trauma, and provide a review of the current literature on this topic. This case study demonstrates a spontaneously ruptured hepatic artery pseudoaneurysm which emerged following a blunt trauma and it also presents current literature studies on the topic. CASE REPORT: A man at the age of 34 years with blunt trauma dating back to 1.5 month was admitted to the emergency department of a hospital with hematemesis and epigastric tenderness. He also had a duodenal ulcer, blood in the gastric lumen and a large pseudoaneurysm that developed from the left hepatic artery. Soon after the diagnosis, the patient worsened and underwent distal gastrectomy and cholecystectomy that included removing the bleeding aneurysm. CONCLUSIONS: Ruptured hepatic artery pseudoaneurysm stands as a deadly condition which has to be diagnosed and managed as soon as possible. Physicians need to take aneurysms of abdominal arteries into consideration after routine diagnostic practises as long as the cause of gastrointestinal haemorrhage is unidentified.

Impact of 18F-FDG PET/CT in the management decisions of breast cancer board on early-stage breast cancer.

PURPOSE: Breast cancer is the most common malignancy accounting for 11.7% of all cancer cases, with a rising incidence rate. Various diagnostic methods, including 18F-fluoro-2-deoxy-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT), play a crucial role in breast cancer diagnosis and staging. However, the unnecessary use of advanced imaging techniques such as PET/CT in early-stage breast cancer can have negative effects on both economics and patients. We aimed to investigate the impact of PET/CT on the management decisions of early-stage breast cancer patients by the breast cancer tumor board. METHODS: A retrospective analysis was performed on a cohort of 81 patients with early-stage breast cancer who were evaluated by breast cancer tumor board from January 2015 to December 2020. Demographic, clinical, and radiographic data, along with surgical procedures and treatment options, were documented and analyzed. RESULTS: The results showed that 18F-FDG PET/CT had a moderate impact on treatment decisions of breast cancer tumor board, as only treatment decisions were changed in 14,86% of the patients. The surgical procedure decision of breast cancer tumor board changed in 12.35% of patients, while 87.65% of patients had consistent decisions before and after PET/CT. Pathological assessments revealed invasive ductal carcinoma as the most prevalent tumor type, and molecular subtypes were predominantly luminal B. PET/CT use had limited impact on surgical procedures and did not significantly alter treatment decisions of breast cancer tumor board in this early-stage breast cancer cohort. CONCLUSIONS: In conclusion, this study highlights the importance of adherence to the guidelines and appropriate use of PET/CT in early-stage breast cancer management. PET/CT should be reserved for cases where it is clinically warranted, considering the potential economic burden and minimal impact on treatment decisions of breast cancer tumor board in this patient population.

Adding Pneumatic Compression Therapy in Lower Extremity Lymphedema Increases Compliance of Treatment, While Decreasing the Infection Rate.

Background: Lymphedema (LE) is a chronic condition that requires lifelong treatment. Although pneumatic compression therapy (PCT) is one treatment option, current algorithms consider it as an adjunct to standard LE. The purpose of this study is to evaluate the importance of adapting PCT for lower extremity LE (LEL) in relation to patient compliance and rate of infection. Materials and Methods: Patients diagnosed with LEL were followed prospectively. Patient demographics, comorbidities, treatment modality, compliance, infection due to LE, and hospitalization were recorded. LEL patients with no-PCT were also recorded in the same time period to evaluate the treatment compliance and the need for physical therapy visits. The no-PCT group received the standard LE care, whereas the PCT group received the standard LE care plus a new-generation pneumatic compression device. Results: A total of 69 patients were enrolled in this study. The PCT group had 50 patients and no-PCT group had 19 patients. The PCT group had median 58.5 months of LE symptoms, while non-PCT patients had median 23 months of LE symptoms (p = 0.11). Infection rates decreased by 32% and hospitalizations due to infection decreased by 14% after PCT treatment had been initiated. Physical therapy needs decreased by 24% after PCT use. At median 18 months, follow-up compliance for PCT was 84%, but compliance for manual lymphatic drainage was almost half (53%) in no-PCT group. Conclusions: PCT leads to a decrease in infection rate, hospital admissions, and physical therapy (PT) visits in clinically significant LEL. Although there is no cost calculation in this study, it can be correlated to significant cost savings due to a reduction of infection and hospitalization and the need for PT visits. Adoption of PCT offers a superior value proposition to not only patients but also the health care system. Cost analysis should be followed.

Assessment of Stromal Elastin Fibers in Breast Cancer and Fibroadenomas: Is There a Correlation With Ultrasound Elastography Findings?

Objective: The stiffness of a breast lesion provides information on the likelihood of malignancy. The most important factor affecting this stiffness is the composition of the extracellular matrix (ECM). The aim of this study was to assess the elastin fiber contents of malignant breast lesions and fibroadenomas and investigate any relationship between the shear wave velocity (SWV) measured by ultrasonography, and the elastin fiber content of lesions. Materials and Methods: Consecutive patients with breast lesions were enrolled. The SWV values of the lesions were analyzed. Histopathological analysis of elastin in excised lesions was performed by the method of Shivas and Douglas. Breast cancer patients were reviewed according to their lymph node status and tumor diameter. The relationship between SWV value and tissue elastin fiber score was analyzed. The correlation between breast cancer grade and elastin fiber score in malignant lesions was investigated. Results: A total of 167 consecutive breast lesions in 167 patients were included in this study (75 invasive cancer, 92 fibroadenomas). High elastic fiber score was significantly more common (p = 0.001) in malignant lesions (n = 61; 81.3%) than fibroadenomas (n = 13; 14.1%). There was a negative correlation between the mean SWV and the elastin fiber score of fibroadenomas (p = 0.001). A low grade in breast cancer was associated with high elastin fiber score (p = 0.01). Conclusion: Malignant lesions tend to have higher elastin fiber scores than fibroadenomas. Elastin fiber assessment may provide additional prognostic information in malignant lesions. Changes in elastin fiber content may account for the variation in elasticity in fibroadenomas.

Treatment Results of Intralesional Steroid Injection and Topical Steroid Administration in Pregnant Women with Idiopathic Granulomatous Mastitis.

OBJECTIVE: Idiopathic granulomatous mastitis (IGM) is an inflammatory and chronic benign breast disease that has proven difficult to diagnose and treat. Since most treatment modalities cannot be used in pregnant patients, the choice of treatment is more difficult and the need for surgery is more pressing. In this first and innovative study, we assess the results of local corticosteroid therapy of IGM in pregnant women. MATERIALS AND METHODS: Pregnant women with IGM were evaluated between June 2017 and May 2019. The six pregnant women were treated using intralesional steroid injections and topical steroid administration. The treatment response was evaluated, both clinically and radiologically, at the end of 2 weeks and once more at the end of 1 month. RESULTS: The median patient age was 26 years. The mean duration of complaints was 4.3 months. The median number of children was 2, and the mean breastfeeding time was 41 months. The predominant complaints at onset were a breast mass or local pain and inflammation in four (66.7%) patients and a breast mass with pain and without signs of local skin inflammation in two (33.3%) patients. Diagnosis was made using a tru-cut biopsy in two patients, and with an incisional biopsy in four patients who had abscess drainage and fistulation to the skin. Five (83.3%) patients achieved a complete response, and one (16.7%) patient responded only partially after the first course of treatment. A second course of treatment was given to the patient with partial response. All patients achieved complete response at the end of the second course of treatment. The mean follow-up time was 19.5 months. During the follow-up period, one patient experienced a recurrence at 4 months after giving birth, and she then received a third course of treatment. Topical and systemic side effects of the corticosteroids were not observed in any patient. CONCLUSION: While the state of pregnancy generally precludes the use of most drugs, the use of local corticosteroid in the treatment of IGM is effective in terms of treatment response, treatment duration, need for surgery, and reduced recurrence and side effects.

Relationship Between Proliferative Breast Lesions and Breast Cancer Risk Factors.

OBJECTIVE: The prognosis of breast cancer (BC) is determined directly based on the stage of disease at the time of diagnosis. Proliferative breast lesions (PBLs) are an important risk factor for BC development. The risk of developing BC varies according to the presence of extent of proliferation in the breast lesions. We aimed to investigate the effect of BC risk factors on the PBLs in this study. MATERIALS AND METHODS: Patients who visited the surgical clinic of the university during the past 6 years who presented with PBLs with or without atypia by fine/core needle aspiration biopsy were included in this study. The relationship between PBLs and BC risk factors such as the age, mass size, Body Mass index (BMI), smoking, sports activity, BC family history, the use of hormone replacement therapy, number of pregnancies, and the duration of breastfeeding were compared. RESULTS: A total of 74 (96.1%) of all patients were women and three were men. The median age of the patients was 38 (range: 19-74) years; the cut-off value of age was 35.5 years. The mean age of patients with PBL-with atypia (PBL-WA) was higher (p=0.005) in the malignant group based on the final pathology and radiological imaging features (for both, p<0.001). The mean size of the mass was large at 2.53±1.33 (1-6) cm; and the cut-off value of the tumor size was 2.5 cm. The mean size was greater in the PBL-WA patients (p=0.171) in the malignant group based on the final pathology and radiological characteristic (respectively, p=0.004 and p=0.016). The mean BMI was 26.8±4.4 kg/m2 (18.8-35.1) and the cut-off value was 25.4 kg/m2. BMI was greater in the PBL-WA group and in the malignant group based on the final pathology (respectively, p=0.002 and p=0.001). Smoking was positive in 66.2% (n=51) of the patients, and it was high in the PBL-WA patients (p=0.001). The percentage of patients with no sports activity was 63.6% (n=49), while it was 20.8% (n=16) for those with once a week sports activity and 15.6% (n=12) for those with twice a week activity. There was family history of BC in 16.9% (n=13) of all patients. The number of positive cases of family history of BC was greater in the malignant group (p=0.001). Hormone replacement therapy was recorded in 11.7% (n=9) of the patients. The mean numbers of pregnancies (2.1±2.4) and breastfeeding duration (32.5±37.4 months) were low in the benign groups due to the relatively lower average age of the patients. CONCLUSION: Based on our analysis, age is an extremely important aspect for assessing PBLs. The age of the patient was statistically significantly greater in the patients with malignant lesions in all groups. The factors lesion size, BMI, smoking habit, and BC family history were also more frequent in the malignant groups. The rate of sports activity was lower in the malignant groups. Thus, it is necessary to evaluate patients individually when evaluating PBLs. It is recommended to evaluate PBLs together with BC risk factors for the better understanding.

A Novel First-Line Treatment Alternative for Noncomplicated Idiopathic Granulomatous Mastitis: Combined Intralesional Steroid Injection with Topical Steroid Administration.

BACKGROUND: Idiopathic granulomatous mastitis (IGM) is a rare form of nonlactational mastitis. Due to the small number of case series and consequently inadequate prospective studies, there is still no consensus on the optimal treatment of IGM. In this study, we aimed to compare the efficacy of intralesional steroid injection with concomitant topical steroids to systemic steroid therapy only in the treatment of noncomplicated IGM. METHODS: Between June 2015 and April 2018, the patients' data was prospectively collected and analyzed retrospectively. The study included a total of 78 female patients diagnosed with IGM. Patients were divided into 2 groups: the local steroid treatment group (intralesional steroid injection with topical steroid administration; group 1, n = 46) and the peroral systemic steroid treatment group (group 2, n = 32). Response to the therapy, side effects, recurrence, the need for surgical treatment, and complication rates were compared. RESULTS: Forty-three patients (93.5%) in group 1 achieved a partial or complete response compared to 23 patients (71.9%) in group 2 after 3 months; this difference was significant (p = 0.012). The recurrence rates were significantly lower in group 1 (8.7%) compared to group 2 (46.9%; p = 0.001), and the need for surgical treatment was significantly less in group 1 (2.2%) than in group 2 (9.4%; p = 0.001). While the complication rates were similar between groups, a higher rate of systemic side effects was observed in group 2. CONCLUSION: Based on the results of our study, combined steroid injection and topical steroid treatment in IGM is as effective as systemic steroid treatment. We suggest that this combination therapy of topical steroids and local steroid injection should be used as first-line therapy in patients with noncomplicated IGM.

Role of Locoregional Treatment in De Novo Stage IV Breast Cancer.

It is estimated that approximately 154000 women in the United States have stage IV breast cancer (BC). A subset of this group has metastatic disease at presentation, known as de novo stage IV disease. De novo stage IV BC accounts for approximately 6% of all BC diagnoses in the United States. Traditionally, stage IV BC patients are treated with primary systemic therapy with a palliative intent reserving possible locoregional treatment (LRT) as last resort. There has been a lot of interest in the role of LRT in de novo stage IV BC for the past decade with mixed conclusions. Although this review is not intended to be a comprehensive overview of all literature regarding this topic to date, we will review the recent findings in literature focusing on the studies with larger sample sizes to investigate the role of LRT in de novo stage IV BC.

Surgical Trends in Breast Cancer in Turkey: An Increase in Breast-Conserving Surgery.

PURPOSE: Breast cancer is the most frequent cancer in women, and there is a great variability in surgical practice for treating that cancer in different countries. The aims of this study were to analyze the effect of guidelines from the Turkish Federation of Breast Diseases Societies on academic institutions that have breast centers and to evaluate surgical practice in Turkey in 2018. PATIENTS AND METHODS: Between January and March 2019, a survey was sent to breast surgeons who were working in breast centers in academic institutions. The sampling frame included 24 academic institutions with breast centers in 18 cities in Turkey to evaluate interdisciplinary differences among breast centers and seven regions in Turkey regarding patients' choices, surgical approaches, and academic institutions. RESULTS: All surgeons responded to the survey, and all 4,381 patients were included. Most of the surgeons (73.9%) were working in a breast center. Multidisciplinary tumor boards were performed in 87% of the breast centers. The average time between clinical evaluation and initiation of treatment was 29 days; the longest time was in Southeast Anatolia (66 days). Only 6% of patients had ductal carcinoma in situ. Sentinel lymph node biopsy was available in every region across the country and was performed in 64.5% of the patients. In 2018, the overall breast-conserving surgery rate was 57.3% in Turkey, and it varied from 72.2% in the Black Sea region to 33.5% in Central Anatolia (P < .001). Oncoplastic breast surgery options were available at all breast centers. However, 25% of the breast centers from the Black Sea region and half the breast centers from Eastern Anatolia and the Mediterranean region did not perform this type of surgery. CONCLUSION: Increasing rates of nonpalpable breast cancer and decreasing rates of locoregional recurrences favored breast-conserving surgery, especially in developed countries. Guidelines from the Turkish Federation of Breast Diseases Societies resulted in more comprehensive breast centers and improved breast health in Turkey.

Transcervical resection of two parathyroid adenomas located on the anterior mediastinum.

The mediastinum is a possible location of ectopic parathyroid adenoma. Most ectopic parathyroid glands in the mediastinum are found in the superior mediastinum within the thymus. In this article, two cases with ectopic mediastinal parathyroid adenomas that were excised via transcervical resection are presented. Preoperative examination of the two cases was performed. Laboratory tests supported hyperparathyroidism. For both patients, the results of radiologic and scintigraphic examinations of the cases were compatible with parathyroid adenoma masses in the anterior mediastinum. Transcervical resection was performed via suprasternal incision through the sternal notch and the posterior wall of the sternum space by blunt dissection with the finger. The soft lesions were removed en bloc in both cases. The parathyroid hormone levels of the two cases decreased dramatically after the operation. Transcervical resection may be an alternative method to major surgery in anterior mediastinal small masses.

Ingested intraabdominal foreign bodies that require surgical intervention.

BACKGROUND: The aim of the present study was to review cases that required surgical intervention to remove ingested foreign bodies. METHODS: Medical records of 7 patients who underwent surgical intervention at the Yüzüncü Yil University Department of General Surgery between 2009 and 2014 after ingesting foreign bodies were reviewed. RESULTS: Female:male ratio was 5:2; mean age was 25 (16-35). Four patients had swallowed pins, 1 patient had swallowed a sewing pin, 1 patient had swallowed a safety pin, and 1 patient had swallowed a wristwatch. The patient who had swallowed the wristwatch had psychiatric disorders. All other patients stated that they had swallowed the objects by accident. CONCLUSION: Most ingested foreign bodies pass smoothly through the gastrointestinal (GI) tract within a week, but those that migrate out of the lumen require surgical intervention due to complications including perforation, abscess, fistula, and peritonitis. Early diagnosis and intervention is crucial to reduce morbidity and mortality. It is believed that sharp and pointed objects that migrate outside of the lumen ought to be removed, lest they cause complications.

The efficiency of apparent diffusion coefficient quantification in diagnosis of acute cholecystitis and in differentiation of cholecystitis from extrinsic benign gallbladder wall thickening.

PURPOSE: The aim of the current study was to assess the efficiency of the apparent diffusion coefficient (ADC) measurement in diagnosis of acute cholecystitis and in differentiation of cholecystitis from extrinsic benign gallbladder wall thickening. METHODS: Forty patients who were diagnosed to have acute cholecystitis by ultrasonographic examination were included in this study. The control group consisted of 18 patients without symptoms of gallstones and cholecystitis whose gallbladder walls were thickened due to cirrhotic ascites. Both groups were examined using diffusion weighted imaging, and the mean ADC values were compared using Student's t-test. RESULTS: The diagnoses of the 40 patients were proven by histopathological examination. The mean ADC values of patients diagnosed with cholecystitis (1.68 ± 0.36 × 10(-3) mm(2)/s) were significantly lower than the mean ADC values of the control group (2.35 ± 0.24 × 10(-3) mm(2)/s) (p < 0.05). Receiver operating characteristics curve analysis based on ADC revealed a cut-off value of 2.04 × 10(-3) mm(2)/s for the diagnosis of cholecystitis, with a sensitivity of 94% and a specificity of 89.7%. CONCLUSION: ADC value quantification may be an efficient method for making a diagnosis of cholecystitis and in differential diagnosis of cholecystitis from the extrinsic benign gallbladder wall thickening that can be seen during the course of cirrhotic ascites.
