2022年首场肿瘤学学术盛会美国临床肿瘤学会胃肠道肿瘤研讨会（ASCO-GI）将于美国时间1月20～22日以线上会议的形式举办，为诸位肿瘤领域学者带来消化道肿瘤最新进展。本次大会依旧有三种类型的交流，按重要性排序分别是：口头汇报（Oral Abstract）、摘要速递（Rapid Abstract）和壁报交流（Poster）。从学术委员会角度看，oral和rapid abstract两个口头汇报类别就是最重要的研究，可能对临床实践带来影响。近日，口头报告（Oral Abstract）和摘要速递（Rapid Abstract）专场题目已于ASCO官网公布，覆盖免疫、靶向和局部治疗等多种内容。【肿瘤资讯】特将两个会场题目整理如下，一起来领略学术的魅力吧！
