下咽-食管双重癌诊疗进展
Chinese Journal of Gerontology（2022）
Abstract
下咽癌是一种以鳞状细胞癌为主,发病于下咽部位的肿瘤,恶性程度高.由于其发生位置隐蔽,且早期无明显症状,所以发现时间晚,治疗难度大.下咽癌可合并发生食管癌,目前国内外指南下咽-食管同时(≤6个月)或异时(>6个月)性原发癌患者在头颈部第二原发癌中比例最高( 15％ ～43％) ,其中鳞癌占95％,国内外相关文献报道的发病率分别为27％ ～35％和7. 2％ ～41. 0％ ﹝1～5﹞.晚期下咽癌和食道癌合并发生时,治疗难度相当大,下咽-食管双重癌是预后不良的独立因素﹝6﹞.本文对下咽-食管癌的研究进展做综述.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
