[On the difficulties and pains in managing peritoneal metastasis from gastrointestinal cancer in China]

Modern clinical oncology has made great achievements over the last century. However, peritoneal metastasis from gastrointestinal cancer, as one of three most common metastasis modalities, was not re-recognized until the end of the last century, and a normative diagnosis and treatment system has been gradually beginning to be formed until today. This comment is to review the development history, reflect on the lessons and experiences in clinical practice, analyze the difficulties on redefinition, deep understanding and clinical management, and pain points on theory construction, technique practice and discipline construction, in the field of gastrointestinal cancer peritoneal metastasis. We suggested a solution to the difficulties and pain points by realizing the fact of burden of peritoneal metastasis, reinforcing technical training, and promoting collaborative researches, aiming to provide reference for the steady development of peritoneal surface oncology.
