Nature Machine Intelligence:深度学习实现前列腺癌病理的高准度分析

深度学习(DL)是实现组织结构数字病理识别和分类的有力方法。其在前列腺癌病理中的表现仍旧需要大量的调查。

深度学习(DL)是实现组织结构数字病理识别和分类的有力方法。其在前列腺癌病理中的表现仍旧需要大量的调查。

最近,有研究人员开发了基于DL的模型,用于对前列腺癌组织全切片成像进行检测。该模型基于一个大的、高质量的和已注释的训练集和一个现代最先进的卷积网络架构(NASNetLarge)。在两个验证队列中,研究人员所建立的模型的总准确度与病理学家相当,原生版本中准确度达到97.3%,使用了基于DL的增强策略时则超过98%。之后,研究人员提出了一种基于生物学意义的DL算法用于对前列腺恶性肿瘤进行格林森分级,且在一些特征良好的验证集中测试时,在患者预后分层方面具有较高的、人类水平的表现。更多的是,研究人员确定了代表整个肿瘤病灶格林森分级最优最小的肿瘤大小(大约560×560µm)。

最后,研究人员指出,他们的方法是在统一的数字病理管道中实现的,并在病理报告中能提供所有相关的肿瘤指标。
