Abstract

Objectives: The most crucial part in the diagnosis of cancer is severity grading. Gleason's score is a widely used grading system for prostate cancer. Manual examination of the microscopic images and grading them is tiresome and consumes a lot of time. Hence to automate the Gleason grading process, a novel deep learning network is proposed in this work.

Methods: In this work, a deep learning network for Gleason grading of prostate cancer is proposed based on EfficientNet architecture. It applies a compound scaling method to balance the dimensions of the underlying network. Also, an additional attention branch is added to EfficientNet-B7 for precise feature weighting.

Result: To the best of our knowledge, this is the first work that integrates an additional attention branch with EfficientNet architecture for Gleason grading. The proposed models were trained using H&E-stained samples from prostate cancer Tissue Microarrays (TMAs) in the Harvard Dataverse dataset.

Conclusions: The proposed network was able to outperform the existing methods and it achieved an Kappa score of 0.5775.

使用EfficientNet进行前列腺活检格里森分级的深度学习网络。

目的:肿瘤的严重程度分级是诊断的关键。格里森评分是一种广泛使用的前列腺癌分级系统。人工检查显微图像并给它们分级是令人厌烦的，而且耗费大量时间。因此，为了实现格里森分级过程的自动化，本文提出了一种新的深度学习网络。方法:在本工作中，提出了一个基于effentnet架构的前列腺癌Gleason分级深度学习网络。它采用复合缩放方法来平衡底层网络的维度。此外，在EfficientNet-B7中增加了一个额外的注意分支，用于精确的特征加权。结果:据我们所知，这是第一个将额外的注意力分支与用于Gleason分级的EfficientNet体系结构集成在一起的工作。所提出的模型使用哈佛Dataverse数据集中来自前列腺癌组织微阵列(tma)的h&e染色样本进行训练。结论:所提出的网络优于现有的方法，Kappa得分为0.5775。
