目前早期或较早期胃癌的发现率虽逐年有所提高,但以晚期胃癌就诊者仍占胃癌病例绝大多数。特别是Ⅳ期胃癌手术时往往对术式的选择感到困难、手术效果较差。有人主张以行简单手术为宜。但是Ⅳ期胃癌包括的范围较广泛,其间病变进展 Although the current discovery rate of early or earlier gastric cancer has increased year by year, patients with advanced gastric cancer still account for the vast majority of cases of gastric cancer. In particular, IV stage gastric cancer is often difficult to select for surgery and has poor surgical results. Some people advocate taking simple surgery. However, stage IV gastric cancer includes a wide range of disease progression during the process.
