Summary Aim: Our goal was to determine the clinical usefulness of TI-201 to identify breast cancer in patients with suspicious breast lesions on clinical examination, and/or abnormal radiologic (mammography and/or ultrasonography) findings. Methods: TI-201 scintigraphy were performed in sixty-eight patients with 70 breast abnormalities (51 palpable, 19 nonpalpable) and compared with mammography and ultrasonography (US). Early (15 min) and late (3 h) images of the breasts were obtained following the injection of 111 MBq (3 mCi) of TI-201. Visual and semiquantitative interpretation was performed. Results: Final diagnosis confirmed 52 malignant breast lesions and 18 benign conditions. TI-201 visualized 47 of 52 (90%) overall malignant lesions. Thirty-eight of 40 (95%) palpable and 9 of 12 (75%) nonpalpable breast cancers were detected by TI-201 scintigraphy. The smallest mass lesion detected by TI-201 measured 1.5x1.0 cm. Eleven breast lesions were interpreted as indeterminate by mammography and/or sonography. TI-201 scintigraphy excluded malignancy in 7 of 8 (88%) patients with benign breast lesions interpreted as indeterminate. Five of the 18 (28%) benign breast lesions showed TI-201 uptake. None of the fibroadenoma and fibrocystic changes accumulated TI-201. TI-201 scintigraphy, mammography and ultrasonography showed 90%, 92%, 85% overall sensitivity and 72%, 56%, 61% overall specificity respectively. Twenty-one of the 28 (75%) axillary nodal metastatic sites were also detected by TI-201. In malignant and benign lesions, early and late lesion/contralateral normal side (L/N) ratios were 1.58 ± 0.38 (mean ± SD) and 1.48 ± 0.32 (p >0.05), 1.87 ± 0.65 and 1.34 ± 0.20 (p<0.05) respectively. The mean early and late L/N ratios of malignant and benign groups did not show statistical difference (p>0.05). Conclusion: Overall, TI-201 scintigraphy was the most specific of the three methods and yielded favourable results in palpable breast cancers, while it showed lower sensitivity in nonpalpable cancers and axillary metastases. Combined use of TI-201 scintigraphy with mammography and US seems to be useful in difficult cases, such as dense breasts and indeterminate breast lesions.

Purpose We performed a first-in-human clinical trial on ultrasound molecular imaging (USMI) in patients with breast and ovarian lesions using a clinical-grade contrast agent (kinase insert domain receptor [KDR] –targeted contrast microbubble [MBKDR]) that is targeted at the KDR, one of the key regulators of neoangiogenesis in cancer. The aim of this study was to assess whether USMI using MBKDR is safe and allows assessment of KDR expression using immunohistochemistry (IHC) as the gold standard. Methods Twenty-four women (age 48 to 79 years) with focal ovarian lesions and 21 women (age 34 to 66 years) with focal breast lesions were injected intravenously with MBKDR (0.03 to 0.08 mL/kg of body weight), and USMI of the lesions was performed starting 5 minutes after injection up to 29 minutes. Blood pressure, ECG, oxygen levels, heart rate, CBC, and metabolic panel were obtained before and after MBKDR administration. Persistent focal MBKDR binding on USMI was assessed. Patients underwent surgical resection of the target lesions, and tissues were stained for CD31 and KDR by IHC. Results USMI with MBKDR was well tolerated by all patients without safety concerns. Among the 40 patients included in the analysis, KDR expression on IHC matched well with imaging signal on USMI in 93% of breast and 85% of ovarian malignant lesions. Strong KDR-targeted USMI signal was present in 77% of malignant ovarian lesions, with no targeted signal seen in 78% of benign ovarian lesions. Similarly, strong targeted signal was seen in 93% of malignant breast lesions with no targeted signal present in 67% of benign breast lesions. Conclusion USMI with MBKDR is clinically feasible and safe, and KDR-targeted USMI signal matches well with KDR expression on IHC. This study lays the foundation for a new field of clinical USMI in cancer.

Objective To compare the capacity of mammography, sonoelastography, B-mode ultrasonography and histological analysis to differentiate benign from malignant breast lesions. Materials and Methods A total of 12 histopathologically confirmed breast lesions were documented. The lesions were assessed by means of mammography, B-mode ultrasonography and sonoelastography, and histopathological analysis was utilized as a gold standard. Sensitivity and specificity were calculated. A receiver operating characteristic (ROC) curve was constructed to evaluate the diagnostic performance of the mentioned techniques. Results Sensitivity and specificity in the differentiation between benign and malignant lesions were respectively 100% and 50% for mammography, 100% and 71% for B-mode ultrasonography, and 67% and 83% for sonoelastography. The area under the ROC curve was calculated for the three imaging modalities and corresponded to 0.792 for mammography, 0.847 for B-mode ultrasonography, and 0.806 for sonoelastography. Conclusion Sonoelastography demonstrated higher specificity and lower sensitivity as compared with mammography and B-mode ultrasonography. On the other hand, B-mode ultrasonography had the largest area under the ROC curve. Sonoelastography has demonstrated to be a promising technique to detect and evaluate breast lesions, and could potentially reduce the number of unnecessary biopsies.

Background: A palpable lump in a woman’s breast could be benign or malignant and it requires prompt evaluation to confirm or exclude cancer. This study aims to establish the correlation between clinical and radiological parameters for provisional diagnosis of breast lumps and the role of histopathology for final diagnosis of these breast lumps.Methods: Total 275 female patients with palpable breast lumps were included in the study, where a detailed history was recorded and clinical examination was done. All patients underwent ultrasonography of the breast along with fine needle aspiration cytology or histopathology, wherever indicated.Results: Benign breast lumps were found more commonly in 18-30 years of age group whereas malignant breast lumps were seen more commonly in the 41-60 years age group and the incidence increased with age. Fixity to skin was present in 5.1% and fixity to chest wall was present in 5.8% respectively, and all of these cases turned out to be malignant.Conclusions: Attributing factors for suspicion of malignant lumps are advanced age, fixity to surrounding structures, presence of ulceration and peau’d orange breast skin appearance. Although for confirmation of malignancy from a suspected breast lump requires either cytology or histopathology of the excised specimen.

Objective To investigate the role of quantitative analysis of T2 relaxation time in the magnetic resonance imaging (MRI) diagnosis of breast cancer. Methods The study enrolled patients with clinical breast masses who were examined using MRI at eight different echo times. The differences in T2 relaxation time of benign and malignant breast lesions were analysed. Results A total of 67 patients (67 breast lesions: 46 malignant, 21 benign) were examined. The mean ± SD T2 relaxation time was significantly lower in the 46 malignant lesions compared with the 21 benign lesions (82.69 ± 15.37 ms versus 95.48 ± 26.51 ms, respectively). The area under the curve was 0.731. Using 79.52 ms as the cut-off between benign and malignant breast lesions, a sensitivity of 85.7% and a specificity of 58.7% were obtained. Conclusions There was a significant difference in T2 relaxation time between benign and malignant breast lesions. The specificity of using T2 relaxation time alone for the differentiation of benign from malignant lesions was not high, but it could constitute a new adjunct in the MRI diagnosis of breast cancer.

BackgroundDifferential diagnosis between benign and malignant breast lesions is of crucial importance relating to follow-up treatment. Recent development in texture analysis and machine learning may lead to a new solution to this problem.MethodThis current study enrolled a total number of 265 patients (benign breast lesions:malignant breast lesions = 71:194) diagnosed in our hospital and received magnetic resonance imaging between January 2014 and August 2017. Patients were randomly divided into the training group and validation group (4:1), and two radiologists extracted their texture features from the contrast-enhanced T1-weighted images. We performed five different feature selection methods including Distance correlation, Gradient Boosting Decision Tree (GBDT), least absolute shrinkage and selection operator (LASSO), random forest (RF), eXtreme gradient boosting (Xgboost) and five independent classification models were built based on Linear discriminant analysis (LDA) algorithm.ResultsAll five models showed promising results to discriminate malignant breast lesions from benign breast lesions, and the areas under the curve (AUCs) of receiver operating characteristic (ROC) were all above 0.830 in both training and validation groups. The model with a better discriminating ability was the combination of LDA + gradient boosting decision tree (GBDT). The sensitivity, specificity, AUC, and accuracy in the training group were 0.814, 0.883, 0.922, and 0.868, respectively; LDA + random forest (RF) also suggests promising results with the AUC of 0.906 in the training group.ConclusionThe evidence of this study, while preliminary, suggested that a combination of MRI texture analysis and LDA algorithm could discriminate benign breast lesions from malignant breast lesions. Further multicenter researches in this field would be of great help in the validation of the result.

Aims: The aim of this study is to find out the prevalence of benign breast lesions and proliferative lesions which are associated with increase risk of breast cancer. This is aimed at influencing the hospital policy on mammographic screening. Study Design: Descriptive retrospective study involving a trend analysis of benign breast lesion, proliferative analysed in the surgical pathology unit of the University of Calabar Teaching Hospital between 1st of January 2012 to October 31st 2014. Place and Duration of Study: Pathology Department of the University of Calabar Teaching Hospital. The study was carried out between March and April 2019. Methodology: Descriptive retrospective study of trend analysis of benign and proliferative breast lesions over the period with literature review. Results: Two hundred and seventeen 217 patients consisting of seven males and two hundred and ten females with a female: Male ratio of 1:0.04. Mean age was 26.4 ± 10.0 years, ranging from 10 to 70 years, with 21-30 (94, 43.5%), as the predominant age and less than 21 years (70, 32.4%) as the second common age group. Seventy four percent of (74%) of the breast lesions were benign non proliferative lesions while 26% were proliferative breast lesions. Of the proliferative lesions, five or 8.9% of the proliferative or 2.33% of the lesions were atypical ductal hyperplasia’s which have a high risk of progression to cancer. Conclusion: Proliferative breast lesions and the premalignant lesions of the breast are not commonly reported in Calabar. An upscale of population screening and mammographic services may improve their yield which will help prevent some invasive breast cancers.

Summary Aim: Investigation of the diagnostic role of technetium-99m methoxyisobutylisonitrile (99mTc sestamibi) scintimammography in non-palpable, suspicious breast lesions described as microcalcification, mass and increased density using mammography. Patients, method: 35 women with non-palpable breast lesions were enrolled in the study. Anterior, left and right lateral, ipsilateral posterior oblique images were obtained 15 min after the injection of 740 MBq of 99mTc sestamibi. All scintigraphic images were evaluated visually and focal increased 99mTc sestamibi uptake was accepted as malignant lesion. Breast lesions were classified as microcalcification (13 women), mammographic mass (16 women) and increased density (6 women). Excisional biopsy was performed in all of them irrespective of the scintigraphic results. Results: The focally increased 99mTc sestamibi uptake was seen in 11 breast lesions with malignant lesions and in 4 breast lesions with benign lesions. The diffuse uptake of 99mTc sestamibi was seen in 18 breast lesions with benign lesions and 2 breast lesions with malignant lesions. There was no false positive result of 99mTc sestamibi in microcalcification group and there was no false negative result of the mammographic mass and increased density groups. Conclusion: Scintimammography might be a complementary method in decision making for the non-palpable, suspicious breast lesions that were evaluated as microcalcification, mass and increased density mammograpically.

Abstract Background Mammography and Sonography are the important sensitive imaging modalities available in detection of breast cancer. Sonoelastography is a relatively new imaging technique which acts as a complementary tool to improve the diagnostic ability of ultrasound for evaluating patients with breast masses. Objective To evaluate the role of sonoelastography characterization information on solid breast lesions over conventional sonography and mammography either benign or malignant lesions to reduce the number of benign biopsies performed. Methods A prospective study was carried at private centers, starting from august 2019 till december 2019. Results The study conducted on 40 patients with palpable breast lesions classified to BIRADS 3 and 4a according to conventional ultrasound and mammographic criteria. Their ages ranged from 18 to '75 years with a mean age 47.72 14.91, 22 cases (55%) had no family history of pervious breast disease, and 18 cases (45%) had family history of pervious breast disease. All patients were subjected to full history taking, clinical examination, conventional gray scale ultrasound, and mammography and ultrasound elastography. All patients underwent histopathological assessment to reach the final diagnosis. Among Studied cases , 28 lesions were sampled by fine needle biopsy (70%) and 12 lesions were sampled by true cut needle (30%) .the results revealed 27 breast lesions were benign (67.5%), 9 malignant lesions (22.5%) and 4 lesions shows atypia (10%) according to histopathological assessment. Among final diagnosis of breast lesions fibro adenoma was the most frequent benign breast lesion detected as 12 lesions from 27 benign breast lesions were fibroadenoma., Also infiltrative ductal carcinoma was the moste frequent among malignant breast lesions as 5 lesions from 9 malignant lesions were infiltrative ductal carcinoma. Conclusion Ultrasoundelastography has significant complementray role beside conventional mammogram and ultrasound in characterization of solid breast lesions.
