Ultrasonography-based Staging of Inflammatory Granulomatous Mastitis and Estimation of Steroid Response.

OBJECTIVE: The aim of this study is to present novel diagnostic ultrasonography-based classification of inflammatory granulomatous mastitis (IGM) and to assess and compare dosage responses of locoregional steroid therapy. MATERIAL & METHODS: From January 2017 through March 2023 total of 230 biopsy-proven IGM patients were reclassified (Grade I, II, and III) according to ultrasonography-based morphological features.The injection applications were grouped in Group1 [40mg/mL between 2017-2019 years] vs. Group2 [80mg/mL between 2019-2023 years] and effectiveness analyzed for each grade in between groups. RESULTS: Total mean age was 31 years old (range: 19-60) with median follow-up period of 7 months. The most common clinical presentation was breast mass accompanying draining skin sinuses of the affected skin and hypoechogenic mass with tubular extensions was the most prevalent feature on USG examination. As per USG-based features 79 (34.3%) patients re-defined as Grade I, 64 (27.8%) as Grade II, and 87 (37.8%) as Grade III.All patients underwent loco-regional steroid injection only. The average treatment in the first group was 6 (±3 SD) with effective dose of 40mg/mL and 4 (±2 SD) with 80 mg/mL in the second group. Generalized linear mixed model investigated effects in between groups (p < 0.05). CONCLUSION: High dose steroid treatment was effective in burnout lesions (Grades II and III), and it was found to be statistically significant in lowering number of treatments irrespective of grade. ADVANCE IN KNOWLEDGE: This novel classification could be a convenient tool in terms of common language between radiologists and clinicians. And our study is the pioneer in comparing steroid dosage with no relapse on IGM patients.

Comparison of the Efficacy of Systemic Versus Local Steroid Treatment in Idiopathic Granulomatous Mastitis: A Cohort Study.

INTRODUCTION: Steroid therapy is known to be effective against granulomatous mastitis. We aimed to compare the efficacy of local versus systemic steroid administration in patients with idiopathic granulomatous mastitis. MATERIALS AND METHODS: This prospective cohort study included 58 patients who had either local (n = 42) or systemic (n = 16) treatment due to granulomatous mastitis between 2015 and 2019. Recurrence rates were determined as per ultrasound and magnetic resonance imaging examinations and the rate of side effects was evaluated as per patient complaints and physical examinations at the end of a 2-year follow-up period. RESULTS: Median doses of 140 mg and 3810 mg were administered to the local and systemic group, respectively. Six (14.3%) patients in the local treatment group and 13 (81.3%) in the systemic treatment group had steroid-related side effects. The local treatment group had significantly fewer side effects than the systemic treatment group (P < 0.001). The recurrence rates were similar in both groups (P > 0.05). CONCLUSIONS: Local steroid injection was as effective as systemic steroid therapy. Compared to systemic therapy, local steroid administration can be considered as a new therapeutic protocol with a lower dose and side effect rate.

Clinical, Histopathological, Imaging, and Treatment Perspectives of Inflammatory Granulomatous Mastitis: Review of the Literature.

Inflammatory granulomatous mastitis is a benign inflammatory disease of the breast mostly presenting in puerperal women. The disease is characterized by recurrent bouts of mastitis with clinical picture of hyperemia, breast mass, and swelling of the breast with or without purulent discharge depending on the severity of the underlying inflammatory process. Although no true prevalence and incidence have been reported in the literature, there are several reported studies setting forth a predilection in specific ethnic groups and/ or geographical areas. Due to the intricate nature of the disease, quite often inflammatory granulomatous mastitis may be mistaken for malignant processes of the breast and even so, there are no pathognomonic imaging appearances to differentiate one from another. The histopathological analysis is a definite way of diagnosis. In this article, we review the imaging manifestations and clinical and histopathological findings along with current trends of available treatment options in the literature and briefly discussed our institutional perspective regarding grading of inflammatory granulomatous mastitis based on ultrasonographic appearances.

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.

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.

Bariatric/Metabolic Surgery in Type 1 and Type 2 Diabetes Mellitus.

The prevalence of type 2 diabetes mellitus (T2DM) and obesity shows a gradual increase nowadays. Despite the introduction of multiagent treatment modalities, many patients with T2DM still do not have good results. Bariatric/metabolic surgery performed in obese patients to attain weight loss has been shown to improve T2DM. Type 1 diabetes mellitus is another type of diabetes that also shows an increase in prevalence. The aim of the present study was to evaluate the literature about the bariatric/metabolic surgical procedures performed in patients with type 1 and type 2 diabetes.

Exploring of the Unpredicted Effects of Olfactory Network Injuries on Mammary Gland Degeneration: A Preliminary Experimental Study.

Purpose of the study: Hypofunctioning breasts are typically considered a dysfunction of higher brain centers that regulate hormonal feedback, and olfactory information has been proposed as a triggering factor for lactation in the maternal body. However, there are no substantive studies regarding whether olfaction disorders and/or loss of olfactory sense may result in breast gland atrophy by causing diminished olfactory stimulation. To fill this gap in the literature, we studied the histologic features of breast glands as a sample model in animals that had undergone an olfactory bulb lesion (OBL). Materials and methods: This study was conducted on 22 rats. Six, eight, and six of them were used as control, SHAM, and OBL groups, respectively. After 10 weeks, the animals were decapitated. Olfactory bulbs and breast glands were stained with Hematoxylin-eosin and tunnel dye. Specimens were analyzed stereologically to evaluate the loss in volume of the olfactory bulbs, total breast follicle volume (TBFV) and Meissner's corpuscles per cubic centimeter, and these two senior metrics were compared with each other statistically. Results: Olfactory bulb volume loss and breast gland atrophy were both detected in study group. Mean TBFV and OB volumes were measured as: (296 ± 89) × 106 µm3/cm3 and 4.43 ± 0.98 mm3 in control (Group I); (264 ± 63) × 106 µm3/cm3 and 3.86 ± 0.81 mm3 in SHAM (Group II) and (194 ± 52) × 106 µm3/cm3 and 1.52 ± 0.36 mm3 in OBL group (Group III). It was noted that the TBFV was significantly diminished, with apoptotic degradation in the olfactory bulbs and breast glands of OBL-applied animals (p < 0.001). Conclusion: It seems that diminished milk secretion is attributable to the degradation of breast glands that results from olfaction loss in OBL animals.

Malignancy risk for thyroid nodules larger than 4 cm and diagnostic reliability of ultrasound-guided FNAB results.

OBJECTIVES: Our aim in the present study was to investigate the relation between thyroid nodule diameter and malignancy, and the diagnostic accuracy of fine needle aspiration biopsy (FNAB) for thyroid nodules larger than 4 cm. MATERIAL AND METHODS: Preoperative patient demographics such as age and gender, thyroid nodule diameter, FNAB results and postoperative pathology results were recorded. The relation between age, gender, thyroid nodule size of the patients and malignancy was examined. Also, the sensitivity, specificity, false negativity, false positivity and accuracy rates of FNBA of the patients whose thyroid nodule size was lower than 4 cm and the ones whose thyroid nodule size was higher than 4 cm were analyzed. RESULTS: There was no significant difference between males and females in terms of malignancy rate (p= 0.15). There was no significant relation between malignancy and patient age (p= 0.92). No significant difference was found between the group with thyroid nodule diameter of > 4 cm and the group thyroid with nodule diameter of <4 cm in terms of malignancy (p= 0.91). In the group with thyroid nodule diameter of > 4 cm, sensitivity, specificity, false negativity, false positivity, and accuracy rates of FNAB were 15%, 100%, 84%, 0%, and 70%, respectively. In the group with thyroid nodule diameter of <4 cm, sensitivity, specificity, false negativity, false positivity, and accuracy rates of FNAB were 53%, 100%, 46%, 0% and 80%, respectively. CONCLUSION: Our study put forward that thyroid nodule diameter is not the only predictor parameter whilst predicting malignancy. However, it was observed that FNAB sensitivity and false negativity were higher when the thyroid nodules with > 4 cm diameter were compared to the thyroid nodules with <4 cm diameter.

Primary Hydatid Cyst in the Axillary Region: A Case Report.

Axillary region is one of the areas where primary hydatid cyst is rare. In this study, we present a case of isolated axillary hydatid cyst in a 40 year-old female patient having applied to our polyclinic with swelling and pain on right axillary. During the breast examination of the patient on right axillary, well-circumscribed semi-mobile mass lesion was detected. On mammary ultrasonography, both breasts were natural. There was necrotic lymphadenopathy on right axillary that was roughly 10×10 cm sized, and locally included cystic patency. Axillary LAP excision was planned for histopathologic diagnosis. Patient was taken to the operation. After it was understood that cyst was hydatic, it was excised with germanium membrane by encircling it with savlon compresses. In order to differentiate primary secondary on post-operative patient, the patient was taken to thoracic and abdomen tomography. No cystic lesions were detected on tomography. Having no problems on follow-ups, the patient was discharged on 3 post-op days with recommendations, and with starting albendazole 10 mg/kg.

Papillary Lesions of Breast.

INTRODUCTION: Papillary breast lesions constitute a pathological heterogeneous group and are characterized by growth in the milk ducts. In this study, we aimed to present in view of literature patients who underwent lumpectomy due to breast mass and with papillary lesion in histopathological examination. MATERIAL METHOD: The pathology records and informations of 42 patients who were operated between 2006-2014 in our clinic and considered to have papillary lesion in histopathological examination were examined retrospectively. The patients were evaluated for age, gender, complaints, lesion localizations, performed surgery, histopathological type, follow-up period and the lesions occurring during follow-up. FINDINGS: The excisional biopsy in the form of lumpectomy was made to 34 patients who were reported as benign papillary lesion in coreneedle biopsy performed. The lesion in 11 patients were marked preoperatively by radiology clinic. 33 patients who had benign papillary lesion in excisional biopsy were followed. Modified radical mastectomy was performed to a total of 9 patients including 1 patient with malignant papillary lesion in excisional biopsy and 8 patients with malignant papillary lesion in coreneed lebiopsy. RESULT: Histopathological diagnosis should be confirmed by performing definitely excisional biopsy in patients who detected benign papillary lesions by coreneedle biopsy and strict clinical follow-up should be made for developing malignancies in patients who detected benign papillary lesions.

The Use of Breast Magnetic Resonance Imaging Parameters to Identify Possible Signaling Pathways of a Serum Biomarker, HE4.

OBJECTIVES: This study aimed to investigate the relationship between breast magnetic resonance imaging (MRI) parameters; clinical features such as age, tumor diameter, N, T, and TNM stages; and serum human epididymis protein 4 (HE4) levels in patients with breast carcinoma and use this as a means of estimating possible signaling pathways of the biomarker, HE4. METHODS: Thirty-seven patients with breast cancer were evaluated by breast MRI and serum HE4 levels before therapy. Correlations between parameters including age, tumor diameter T and N, dynamic curve type, enhancement ratio (ER), slope washin (S-WI), time to peak (TTP), slope washout (S-WO), and the serum level of HE4 were investigated statistically. Human epididymis protein 4 levels of early and advanced stage of disease were also compared statistically. RESULTS: Breast MRI parameters showed correlation to serum HE4 levels and correlations were statistically significant. Of these MRI parameters, S-WI had higher correlation coefficient than the others. Human epididymis protein 4 levels were not statistically different in early and advanced stage of disease. CONCLUSIONS: High correlation with MRI parameters related to neoangiogenesis may indicate signaling pathway of HE4.

Granulomatous Mastitis: A Ten-Year Experience at a University Hospital.

OBJECTIVE: In this study we aimed to define clinical, radiologic and pathological specialties of patients who applied to General Surgery Department of Atatürk University Medical Faculty with granulomatous mastitis and show medical and surgical treatment results. With the help of this study we will be able to make our own clinical algorithm for diagnosis and treatment. MATERIALS AND METHODS: We searched retrospectively addresses, phone numbers and clinical files of 93 patients whom diagnosed granulomatous mastitis between a decade of January 2001 - December 2010. We noted demographic specialties, ages, gender, medical family history, main complaints, physical findings, radiological and laboratory findings, medical treatments, postoperative complications and surgical procedures if they were operated; morbidity, recurrence and success ratios, complications after treatment for patients discussed above. RESULTS: In this study we evaluated 93 patients, 91 females and 2 males, with granulomatous mastitis retrospectively who applied to General Surgery Department of Atatürk University Medical Faculty between January 2001 and December 2010. Mean age was 34.4 years. The diagnosis was confirmed by histopathologic examination of the lesions. Seventy three patients had idiopathic granulomatous lobular mastitis and 20 patients had specific granulomatous mastitis IGM (18 tuberculosis mastitis, 1 alveolar echinococcosis and 1 silk reaction). All the patients had surgical debridement or antibiotic, and anti-inflammatory treatment with results bad clinical response before applied our clinic. CONCLUSION: Empiric antibiotic therapy and drainage of the breast lesions are not enough for complete remission of idiopathic granulomatous mastitis. The lesion must be excised completely. In selected patients, corticosteroid therapy can be useful. In the patients with tuberculous mastitis, abscess drainage and antituberculous therapy can be useful, but wide excision must be chosen for the patients with recurrent disease.

Sonoelastography findings for idiopathic granulomatous mastitis.

OBJECTIVES: In this paper we describe sonoelastography findings for idiopathic granulomatous mastitis (IGM), the clinical and radiological features of which often mimic those of breast carcinoma. MATERIALS AND METHODS: In this retrospective study, sonoelastography findings for patients with pathologically proved IGM were studied. Twenty-seven patients with pathologically proved IGM were enrolled in the study. All were female, and the mean age was 37.81 years (standard deviation 7.10 years; range 24 to 56 years). Elasticity scores (ES), strain ratios (SR), and elastic diameters (ED) were evaluated for the lesions. RESULTS: Ten lesions (37.0 %) were diffuse, six (22.2 %) were tubular, six (22.2 %) were a mass, and five (18.5 %) were cystic in appearance on ultrasonography. On sonoelastography, mean ES ± standard deviation was 1.66 ± 0.55 (between 1.00 and 3.00); mean SR ± standard deviation was 1.10 ± 0.79 (between 0.29 and 4.00). ED was no different between grey-scale and sonoelastogram images. CONCLUSIONS: The features of idiopathic granulomatous mastitis suggest it is benign in nature.

Value of MRI sequences for prediction of invasive breast carcinoma size.

INTRODUCTION: In this retrospective study, we compared transverse short tau inversion recovery (STIR), transverse diffusion-weighted imaging (DWI), apparent diffusion coefficient (ADC) map and first post-contrast fat-saturated fast low-angle shot (FLASH) 3D T1 with pathology results in terms of their accuracy in estimating breast carcinoma size. METHODS: Magnetic resonance imaging data for 47 patients with invasive breast carcinoma, who were treated surgically, were reviewed. The longest dimension (LD) of the index lesion was measured using STIR, DWI, ADC map and first post-contrast FLASH 3D T1, and this was compared with the LD measured on the pathology specimen. RESULTS: All four MRI sequences overestimated the LD by an average of about 1 mm with 95% limits of agreement approximately 0 to 2 mm. This is not considered to be clinically significant in tumours of 10 mm or larger. CONCLUSION: Magnetic resonance imaging serves as an accurate tool in sizing breast carcinomas. ADC may be a useful evaluation tool for sizing carcinomas without requiring contrast material.

Factors affecting hypocalcaemia following total thyroidectomy: a prospective study.

OBJECTIVE: After thyroidectomy hypocalcaemia is the most significant complication for clinicians. In this study, we investigated the factors associated with development of hypocalcaemia after thyroidectomy. MATERIALS AND METHODS: We investigated the patients prospectively for age, gender, preoperative diagnosis, hormonal status, operative time, operating surgeon, existence of parathyroid gland injury at the operation, parathyroid gland auto-transplantation, preoperative use of anti-thyroid drugs and amount of bleeding at the operation. After operation in 1 and 2 days, serum calcium and phosphor, and in the 1 day parathyroid hormone values were evaluated. The chi-square test was applied in the analysis of categorical variables. Logistic regression model was used to determine the risk of hypocalcaemia in the univariate analysis. RESULTS: Hypocalcaemia developed in 47 of 196 patients. Female gender, preoperative diagnosis of thyroid cancer and toxic nodular goitre, <3cm nodule size, parathyroid injury and auto-transplantation and low vitamin D levels were factors found to be associated with hypocalcaemia in the Logistic regression analysis. CONCLUSION: The factors associated with hypocalcaemia were defined to be "gender, preoperative diagnosis, parathyroid gland injury, nodule size and vitamin D deficiency", it is a multifactorial problem and it would not be proper to define a few etiological factors.

Completion thyroidectomy in differentiated thyroid cancer: When to perform?

OBJECTIVE: Completion thyroidectomy is recommended in patients who have been diagnosed with differentiated thyroid cancer on histopathological evaluation, if their first operation was a conservative approach. The critical issue is when to do the second operation. MATERIAL AND METHODS: The medical records of 66 patients who underwent completion thyroidectomy for the treatment of differentiated thyroid cancer in our clinic between 2006-2013 were retrospectively analyzed. All data were compared after patients were divided into two groups according to the interval between the first surgery and completion thyroidectomy. RESULTS: Fifty-two patients (78.8%) were women and 14 patients (21.2%) were male. Completion thyroidectomy was performed 10-90 days after the initial surgery (group 1) in 26 patients, whereas it was performed later than 90 days in 40 patients (group 2). Temporary hypoparathyroidism occurred in two patients (7.7%) in group 1, and in 3 patients (7.5%) in group 2. Transient recurrent laryngeal nerve palsy was observed in 1 patient (3.9%) in group 1, and in 1 patient (2.5%) in group 2. There were no permanent morbidities in both groups. Residual tumor rate after completion thyroidectomy was 45.5%. There was no statistically significant difference between the two groups in terms of complications after completion thyroidectomy. CONCLUSION: Although in some studies it is recommended that completion thyroidectomy should be performed either before scar tissue development or after clinical remission of scar tissue, edema and inflammation, we believe that timing of surgery has no effect on morbidity.

Breast lesions with high signal intensity on T1-weighted MR images.

Magnetic resonance imaging of the breast supplies much information concerning the signal characteristics of a lesion. Among these, high signal intensity on non-fat saturated T1-weighted imaging (WI) is a special finding. Such a finding may result from different causes, such as a paramagnetic substance or fatty, bloody or proteinaceous content. In this article, we present hyperintense breast lesions on T1-WI.

Magnetic resonance imaging findings of breast juvenile papillomatosis.

Juvenile papillomatosis is a rare disease affecting young women. Here we present magnetic resonance imaging features of two cases with histopathologically proven juvenile papillomatosis of the breast and review some of the relevant literature. Case 1 exhibited bilateral, well-bordered breast masses, with complex cystic and solid components. The kinetic evaluation showed continuous and plateau patterns. Case 2 featured a giant mass with a few cystic and many solid nodular components and filled the entire right breast. The kinetic evaluation showed a continuous curve.
