Prospects for gastric cancer treatment based on the revisions of Japanese Gastric Cancer Classification / 中国实用外科杂志

ABSTRACT

Japanese gastric cancer classification marks the lymph nodes associated with gastric cancer metastasis in groups, which allows the surgeons and pathologists to operate as per a uniform specification to obtain the distribution of metastatic lymph nodes in every case. Through a substantial number of cases, the rules and pathways of lymph node metastasis are summarized, thus laying a theoretical foundation for radical gastrectomy. From the simple to the complex, and then to the refined and expansive, the classification categorizes subgroup studies to better rationalize the lymph node dissection; and expands the researches on marker range to investigate the role of enlarged surgery.Researches over decades have explored the law of lymph node metastasis to the extreme, and the surgical efficacy of gastric cancer near limit. Thus, shortly after the mature treatment model was established as the Gastric Cancer Treatment Guidelines by Japanese experts, the revised classification in2010 altered the criterion for staging gastric cancer from the location of metastatic lymph nodes to the number of metastases. This indicates that the exploration of surgical approaches to gastric cancer is basically completed, and the`future efficacy improvement of gastric cancer depends on comprehensive therapy. The formation of radical gastrectomy is the result of multidisciplinary collaborative research.Surgery should still be performed in strict accordance with the specification. Postoperative grouped inspection of lymph nodes has great significance for determining the surgical outcome and prognosis.
