Deep learning-based CAD has been gaining popularity for analyzing histopathological images, however, few works have addressed the problem of accurately classifying images of breast biopsy tissue stained with hematoxylin and eosin into different histological grades. (2018) used the pre-trained model of ResNet_V1_152 (He et al., 2016) to perform diagnosis of benign and malignant tumors as well as diagnosis based on multi-class classification of various subtypes of histopathological images of breast cancer in BreaKHis. Bergstra, J., and Bengio, Y. (2013) proposed a new cascade random subspace ensemble scheme with rejection options for microscopic biopsy image classification in 2012. Comput. The experimental results on BreaKHis achieved the accuracy of 95.4%. The experimental results in Table 4 for binary classification show that Se>98%, Sp>92%, PPV>96%, and DOR>100 on each dataset regardless of magnification factor or the effects of augmentation (raw or augmented). 2020 Apr 19;12(1):26. doi: 10.1186/s13321-020-00428-5. An important difference between the Inception_V3 and Inception_ResNet_V2 networks is that the latter is equipped with residual connections. Also, using the expanded histopathological image datasets of breast cancer can obtain better classification and diagnosis results. ∙ 0 ∙ share Empirical evaluation of breast tissue biopsies for mitotic nuclei detection is considered an important prognostic biomarker in tumor grading and cancer progression. The best results were also obtained using the extended datasets. (2017) proposed a class structure-based deep convolutional network to provide an accurate and reliable solution for breast cancer multi-class classification by using hierarchical feature representation. Being able to automate the detection of metastasised cancer in pathological scans with machine learning and deep neural networks is an area of medical imaging and diagnostics with promising potential for clinical usefulness. Furthermore, the clustering results produced by K-means using features extracted by Inception_ResNet_V2 and transformed by the proposed AE are much better, in terms of ARI, AMI, SSE, and ACC, than the results produced with features extracted only by Inception_ResNet_V2. The change in the loss function during the training of Inception_ResNet_V2 on raw and augmented data with 40 factor magnification, (A) binary classification, (B) multi-class classification. In addition, the values of AUC and Kappa in Table 2 tell us that our models are perfect and have obtained almost perfect agreement for binary classification of histopathological images of breast cancer. IEEE Transac. J. Adv. AUC is the area under the ROC curve, which is another widely used metric for evaluating binary classification models. Remote computer-aided breast cancer detection and diagnosis system based on cytological images. Computer-aided breast cancer diagnosis based on the analysis of cytological images of fine needle biopsies. The definitions of the criteria are shown in Equations (2–9). The clustering accuracies of histopathological images of breast cancers are not as good as classification accuracies because the latter used label information. ARI is defined in (11) and uses the following variables: a (the number of pairs of samples in the same cluster before and after clustering), b (the pairs of samples in the same cluster while partitioned into different clusters by the clustering algorithm), c (the pairs of samples that are from different clusters but are grouped into the same cluster incorrectly by the clustering algorithm), and d (the number of pairs of samples from different clusters that are still in different clusters after clustering). Med. One reason leading to the poor classification results for multi-class classification is the imbalance in sample distribution. Pattern Recog. Procedia Technol. Equation (9) is the Kappa coefficient, where P0 is the image level test accuracy defined in (6), and Pe is the ratio of the sum of the product of the number of real images in each category and the predicted number of images in that category to the square of the total samples. doi: 10.1038/nature21056, Filipczuk, P., Fevens, T., Krzyzak, A., and Monczak, R.

Binary and multi-class classification comparison between our experimental results and the ones available from other studies /%. Breast Cancer Histopathological Image Classification: a Deep Learning Approach. Breast cancer remains the most common type of cancer and the leading cause of cancer-induced mortality among women with 2.4 million new cases diagnosed and 523,000 deaths per year. Here, MI(U, V) denotes the mutual information between two partitions U and V, and E{MI(U, V)} represents the expected mutual information between the original partition U and the clustering V. H(U), H(V) are the entropy of the original partition U and the clustering V, respectively. doi: 10.7717/peerj.8668. HHS The experimental results demonstrate that using our proposed autoencoder network results in better clustering results than those based on features extracted only by Inception_ResNet_V2 network. Friedman's test is considered preferable for comparing algorithms over several datasets without any normal distribution assumption (Borg et al., 2013). (2018). It offers a statistically significant improvement compared to the results from available references that we can find. This research project imple-ments the Convolutional Neural Network(CNN) model based on deep learning and World Cancer report 2008: IARC Press. These studies can be divided into two categories according to their methods: one is based on traditional machine learning methods, and the other is based on deep learning methods. Breast cancer is associated with the highest morbidity rates for cancer diagnoses in the world and has become a major public health issue. These classifiers were tested on a set of 737 microscopic images of fine needle biopsies obtained from 67 patients, which contained 25 benign (275 images) and 42 malignant (462 images) cases. Here, IRV2+Kmeans represents the clustering results of K-means with the features extracted by Inception_ResNet_V2, while IRV2+AE+Kmeans represents the clustering results of K-means based on the features transformed by our proposed AE using the features extracted by Inception_ResNet_V2. Consequently, this can lead to the final model producing poor classification results. Eng. Our experimental results of the supervised histopathological image classification of breast cancer and the comparison to the results from other studies demonstrate that Inception_V3 and Inception_ResNet_V2 based histopathological image classification of breast cancer is superior to the existing methods. The values of Kappa in Table 4 show that our models are perfect when applied to augmented datasets for multi-class classification. However, the process of developing tools for performing this analysis is impeded by the following challenges. Xie, J., Hou, Q., Shi, Y., Peng, L., Jing, L., Zhuang, F., et al. This suggests that the histopathological images of breast cancer should be grouped into 2 categories of benign and malignant tumors, which is consistent with the real case. Identity mappings in deep residual networks. 63, 1455–1462. Results of binary and multi-class classification on raw and augmented data using Inception_ResNet_V2/%. 2020 May;4:480-490. doi: 10.1200/CCI.19.00126. The inception module of size 8 × 8 in two networks, (A) Inception_V3,…, The Inception_ResNet_V2 network structure for…. Therefore, computer-aided (Aswathy and Jagannath, 2017) analysis of histopathological images plays a significant role in the diagnosis of breast cancer and its prognosis. The interval of SSE is [−1, 1]. Adv Exp Med Biol. They proposed two different architectures: the single task CNN used to predict malignancy, and the multi-task CNN used to predict both malignancy and image magnification level simultaneously. RL also made substantial contributions to the conception and design of the work. 2014:17. doi: 10.1186/1687-6180-2014-17, Keywords: histopathological images, breast cancer, deep convolutional neural networks, autoencoder, transfer learning, classification, clustering, Citation: Xie J, Liu R, Luttrell IV J and Zhang C (2019) Deep Learning Based Analysis of Histopathological Images of Breast Cancer. Paired rank comparison of algorithms in ACC_IL and AII_PL for binary and multi-class classification. Figure 6 plots the curves of SSE with the number of clusters on the 40X original dataset of histopathological images of breast cancer. To test whether the experimental results from Inception_ResNet_V2 are superior to those from Inception_V3 on small datasets or not, these two networks are adopted in this paper to perform classification of the histopathological images of breast cancer. All of the work in this paper demonstrates that the deep convolutional neural network Inception_ResNet_V2 has the advantage when it comes to extracting expressive features from histopathological images of breast cancer. Front. “Delving deep into rectifiers: Surpassing human-level performance on imagenet classification,” in Proceedings of the IEEE international conference on computer vision (Santiago). After doing this, the sample number of each subclass was approximately the same. All of these sub-datasets are classified into benign and malignant tumors. The external metrics depend on the true pattern of the dataset. We demonstrate that our experimental results are superior to the ones available in other studies that we have found, and that the Inception_ResNet_V2 network is more suitable for performing analysis of the histopathological images of breast cancer than the Inception_V3 network. IEEE; 2017. p. 348–353. Traditional feature extraction methods, such as scale-invariant feature transform (SIFT) (Lowe, 1999) and gray-level co-occurrence matrix (GLCM) (Haralick et al., 1973), all rely on supervised information. From observing this confusion matrix, we can see that many benign tumors are incorrectly classified as malignant tumors. Here, we only retrained the Inception_ResNet_V2 network because it performed better than the Incepiton_V3 network on the raw datasets. The models based on the Inception_ResNet_V2 network can get perfect agreement for multi-class classification of breast cancer histopathological images, except when applied to the 400X dataset (which still achieves substantial agreement). Deep learning methods typically are neural network based learning machines with much more layers than the usual neural network. The results in Figure 5 show that the value of the loss function decreases much faster and more smoothly converges to a much smaller value on the extended datasets than on the raw datasets. Therefore, the deep learning network of Inception_ResNet_V2 with residual connections is very suitable for classifying the histopathological images of breast cancer. Therefore, we used Inception_ResNet_V2 to extract features from breast cancer histopathological images to perform unsupervised analysis of the images. (1967). Figure 2 displays the differences in the construction of the Inception module with a size of 8 × 8 between Inception_V3 and Inception_ResNet_V2. The results in Figure 6 also reveal that the clustering results of IRV2+AE+Kmeans are better than those from IRV2+Kmeans. First, histopathological images of breast cancer are fine-grained, high-resolution images that depict rich geometric structures and complex textures. The variability within a class and the consistency between classes can make classification extremely difficult, especially when dealing with multiple classes. ABSTRACT Breast cancer is one of the most common and deadly types of cancer that develops in the breast tissue of women worldwide. It only uses the similarities between samples to group them into different clusters, such that the samples in the same cluster are similar to each other and dissimilar to those from other clusters. Procedia Comput. Then, to overcome the influence from the imbalanced histopathological images in subclasses, we balanced the subclasses with Ductal Carcinoma as the baseline by turning images up and down, right and left, and rotating them counterclockwise by 90 and 180 degrees. Also, the different subclasses in the same class are often misclassified, such as samples from LC being recognized as samples from DC. 12 (2016) between four machine learning algorithms, including SVM, DT, NB and KNN, on the Wisconsin Breast Cancer dataset, which contains 699 instances (including 458 benign and 241 malignant cases). It is clear that DOR will become infinity when the related classifier is perfect. (2016a) in 2016. Copyright © 2019 Xie, Liu, Luttrell and Zhang. Biol. Kingma, D. P., and Ba, J. To realize the development of a system for diagnosing breast cancer using multi-class classification on BreaKHis, Han et al. 03/17/2020 ∙ by Anabia Sohail, et al. 19. Bengio Y., Courville A., Vincent P. (2013). The 1,536-dimension features are extracted by using Inception_ResNet_V2 to process histopathological images of breast cancer, and the K-means clustering algorithm is adopted to group these images into proper clusters. (2016) proposed to classify breast cancer histopathological images independently of their magnifications using CNN (convolutional neural networks). One-class kernel subspace ensemble for medical image classification. 10.1016/j.procs.2016.04.224 Besides the above analysis, we further verify the power of our approaches for analyzing the breast cancer histopathological images using the p-value of AUC and Kappa. FP is the number of images that were incorrectly recognized as malignant tumor in the testing subset. The highest average accuracy achieved … In this way, the 2-dimension features of the histopathological images of breast cancer can be obtained for K-means in low dimensional space. Here, INV3_Raw denotes the results obtained by using Inception_V3 on original dataset. Although the diagnosis of breast cancers has been performed for more than 40 years using X-ray, MRI (Magnetic Resonance Imaging), and ultrasound etc. Furthermore, they are unable to extract and organize discriminative information from data (Bengio et al., 2013). This is especially true when doing multi-class classification with the histopathological images of breast cancer that we used. Prognostic analysis of histopathological images using pre-trained convolutional neural networks: application to hepatocellular carcinoma. Bengio, Y., Courville, A., and Vincent, P. (2013). (eds). (2013) used four clustering algorithms to perform nuclei segmentation for 500 images from 50 patients with breast cancer. We calculate AUC in our experiments by calling the roc_auc_score function from the Scikit-learn library that is available as a Python package (sklearn). Wei B, Han Z, He X, Yin Y. 4, 1553–1568. In the end, the final extracted features are only some low-level and unrepresentative features of histopathological images. J. 1:140216. doi: 10.1098/rsos.140216. Here, χ2 is chi-square, df is the degree of freedom, and p is p-value. For each magnification factor dataset, we chose the DC subclass as the baseline, and amplified each of the remaining subclasses by turning images up and down, left and right, and using counterclockwise rotation of 90°and 180°. It is first used to find the most proper number of clusters of the histopathological images of breast cancer.

Sci Rep. 2021 Jan 8;11(1):179. doi: 10.1038/s41598-020-80068-9. On one hand, we use advanced deep convolutional neural networks, including Inception_V3 (Szegedy et al., 2016) and Inception_ResNet_V2 (Szegedy et al., 2017), combined with transfer learning techniques to classify the histopathological images of breast cancer (Pan and Yang, 2010). Then, we froze all of the parameters before the last layer of the networks. This is true for both experiments on binary and multi-class classification of histopathological images of breast cancer. 10.1016/j.imu.2016.11.001 They also are very sensitive to different sizes and complex shapes. 9, 316–322. CZ and JL discussed with JX and RL about the technique details, then CZ and JL revised the paper critically for important intellectual content. Here, the patient score is the ratio of Nrec to NP, that is, the ratio of correctly identified images of patient P to all the images of patient P in the testing subset. In addition, Nawaz et al. In order to ensure the universality of the experimental results in the classification task, the datasets of the four magnification factors were randomly partitioned into training and testing subsets according to the proportion of 7:3. DOR expresses the ratio of the product of TP and TN to the product of FP and FN. 2020 Jul;190:105351. doi: 10.1016/j.cmpb.2020.105351. Bayramoglu N., Kannala J., Heikkilä J., editors. All of our experimental results demonstrate that Inception_ResNet_V2 network based deep transfer learning provides a new means of performing analysis of histopathological images of breast cancer. 10:80. doi: 10.3389/fgene.2019.00080. 2018 Feb;13(2):179-191. doi: 10.1007/s11548-017-1663-9. doi: 10.1001/jamaoncol.2018.2706, Motlagh, N.

The automatic diagnosis of breast cancer by analyzing histopathological images plays a significant role for patients and their prognosis. Neural Inform. Comparison of Radiomics-Based Machine-Learning Classifiers in Diagnosis of Glioblastoma From Primary Central Nervous System Lymphoma. Methods: An established whole slide image processing pipeline based on deep learning was used to perform global segmentation of epithelial and stromal tissues. Table 4 shows the experimental results on the original and expanded datasets for binary and multi-class classification, respectively. have been developed to overcome the drawbacks of histopathological image analysis. The batch_size is set to 32 in the experiments, and the initial learning rate is 0.0002 (Bergstra and Bengio, 2012). “Deep residual learning for image recognition,” in Proceedings of the IEEE Conference on Computer Vision and Pattern Recognition (Las Vegas, NV). Sci. Since the operation of Whole-Slide Imaging is complex and expensive, many studies based on this technique use small datasets and achieve poor generalization performance. We consider both binary and multi-class classification of breast cancer histopathological images with Inception_ResNet_V2 when calculating the p-value for AUC and Kappa. In summary, the best ACC scores of IRV2+AE+Kmeans and IRV2+Kmeans are 76.4 and 59.3%, respectively. Rep. 7:4172. doi: 10.1038/s41598-017-04075-z, Haralick, R. M., Shanmugam, K., and Dinstein, I. H. (1973). However, traditional feature extraction methods can only extract some low-level features of images, and prior knowledge is necessary to select useful features, which can be greatly affected by humans. 2020 Oct 20;34:140. doi: 10.34171/mjiri.34.140. Deep learning techniques can extract high-level abstract features from images automatically. The first several layers are characteristic transformation via the traditional convolutional layers and the pooling layers, and the middle part is composed of multiple Inception modules stacked together. Classification of breast cancer histology images using convolutional neural networks. Sample descriptions for the BreaKHis dataset are shown in Table 1. In this way, the breast cancer histopathological images can be represented in a very low dimensional space. Therefore, we adopt two deep convolutional neural networks, specifically Inception_V3 and Inception_Resnet_V2, to study the diagnosis of breast cancer in the BreaKHis dataset via transfer learning techniques. who provided the database of BreaKHis for us to use, and the other involved researchers for their work to stimulate this research. There are 2 encode layers with neuron sizes of 500 and 2, respectively, and there are 2 corresponding decode layers to reconstruct the original input. As a result, Araújo et al. The Inception_V3 (Szegedy et al., 2016) and Inception_ResNet_V2 (Szegedy et al., 2017) networks were proposed by Szegedy et al. JX and CZ gave approval for publication of the content. Micro-F1 is defined as F1 but depending on the precision and recall defined by the sum of TP (true positive), FP (false positive), and FN (false negative) for all classes. Biometrics 33, 159–174. In addition, the values of AUC in Table 4 show that our models are excellent. Generally adopted workflows in computer-aided diagnosis image tools for breast cancer diagnosis have focused on quantitative image analysis [5]. “Representation learning: A review and new perspectives,” in IEEE Transactions on Pattern Analysis and Machine Intelligence 35, 1798–1828. The bold fonts denote the best results. It is also supported by the National Key Research and Development Program of China under Grant No. The experimental results in Table 4 show that the experiments on extended datasets have produced much better results than those performed on the raw datasets. bioRxiv 242818. doi: 10.1101/242818, Nawaz, M., Sewissy, A. This makes the extracted features unable to thoroughly represent the subclasses with fewer samples. (2014) proposed a diagnosis system for breast cancer using nuclear segmentation based on cytological images. Appl. 61673251. The range of AUC is [0, 1] (Bradley, 1997), with higher values representing better model performance. Kowal, M., Filipczuk, P., Obuchowicz, A., Korbicz, J., and Monczak, R. (2013). So, there are 8 subclasses in total, including 4 benign tumors (A, F, PT, and TA) and 4 malignant tumors (DC, LC, MC, and PC). Table 3. After that, the parameters of the fully-connected layer are trained on the histopathological images of breast cancer. (eds) (2015). Mathews, A., Simi, I., and Kizhakkethottam, J. J. Comparing the results in Table 2 for binary and multi-class classification, we can see that the performance of multi-class classification is worse than that of the binary classification. To save the original organization structure and molecular composition, each image was taken by a pathologist from a patient's breast tissue section using a surgical biopsy. (2018). NIH USA.gov. The powerful feature extraction capability of the Inception_ResNet_V2 network was used to extract features of the histopathological images of breast cancer for the linear kernel SVM and 1-NN classifiers. Bayramoglu, N., Kannala, J., and Heikkilä, J. This is reflected by the data marked with red underlines, especially the results of multi-class classification on the expanded datasets. Deep learning-based approaches have recently gained popularity for analyzing histopathological images of human breast cancer. This work is supported in part by the National Natural Science Foundation of China under Grant No. IEEE Syst. We conducted Friedman's test at α = 0.05 using the results of algorithms on all datasets in terms of ACC_IL and ACC_PL for binary and multi-class classification shown in Table 5. Images are processed using histogram normalization techniques. The Adam (adaptive moment estimation) (Kingma and Ba, 2014) algorithm was used in the training process to perform optimization by iterating through 70 epochs using the histopathological image dataset of breast cancer. Deep Object Detection based Mitosis Analysis in Breast Cancer Histopathological Images. Using this autoencoder, the 1,536-dimension feature vector extracted by the Inception_ResNet_V2 network for a breast cancer histopathological image will be transformed to 2-dimenision feature vector via training the layers depicted in Figure 4A. Focusing on a computer-based qualification for breast cancer diagnosis, the present study proposes two deep learning architectures to efficiently and effectively detect and classify mitosis in a histopathological tissue sample. Science 313, 504–507. Adam: a Method for Stochastic Optimization. Classification 2, 193–218. Random search for hyper-parameter optimization. First, we adapted Inception_V3 and Inception_ResNet_V2 architectures to the binary and multi-class issues of breast cancer histopathological image classification … (Stenkvist et al., 1978), biopsy techniques are still the main methods relied on to diagnose breast cancer correctly. PLoS ONE 12:e0177544. “Breast cancer histopathological image classification using convolutional neural networks,” in 2016 International Joint Conference on Neural Networks (IJCNN).
