概括
像GatorTron这样的域特定语言模型在预测晚期上皮质卵巢癌 (aEOC) 细胞减少手术笔记的结果方面表现有希望. 然而,仅仅使用文本来预测术后事件仍然具有挑战性.
科学领域:
- 自然语言处理 (NLP) 是一种自然语言处理.
- 医疗保健中的机器学习
- 在瘤学瘤学.
背景情况:
- NLP的进步为医疗保健提供了潜力,但对临床笔记的分析发展不足.
- 基于变压器的深度神经网络正在探索用于预测外科手术结果.
- 先进阶段的上皮卵巢癌 (aEOC) 细胞减少提出了复杂的数据分析挑战.
研究的目的:
- 研究深度学习模型的有效性,特别是基于变压器的NLP,用于预测aEOC的手术内和术后结果.
- 将一个通用模型 (RoBERTa) 与一个特定领域的模型 (GatorTron) 进行比较,用于分析非结构化的手术笔记.
- 评估NLP模型的预测能力,使用临床文本来评估EOC细胞还原手术的结果.
主要方法:
- 评估了RoBERTa和GatorTron模型在八个二进制分类任务中使用来自aEOC患者的560个手术记录.
- 连接"操作发现"和"操作说明"以增强模型的上下文信息.
- 将预测结果转换为二进制特征以进行分类.
主要成果:
- 在从临床文本预测结果方面,域特定模型 (GatorTron) 通常优于一般模型 (RoBERTa).
- 两种模型都面临着难以预测术后事件的困难,例如重大并发症和住院时间.
- 这些局限性表明,仅仅手术笔记可能无法完全捕捉术后复杂度.
结论:
- 采用特定领域的语言模型为瘤学中的临床文本分析提供了切实的好处.
- 利用NLP的人工智能系统可能会提高aEOC的现代医疗保健服务.
- 需要进一步的研究,以结合额外的数据源来预测复杂的术后结果.

Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...
