有调查数字显示,全世界胃癌发病率为13.86/10万,仅次于肺癌居第二位。我国是胃癌的高发区,全国肿瘤登记地区2009年的胃癌发病率为36.21/10万,为世界水平的2.6倍。目前,手术是惟一有可能治愈胃癌的手段,只要病人全身情况允许,又无明确的远处转移时,均应实施手术。对于中晚期胃癌,因其有较高的复发率和转移率,必须积极地辅以术前和术后的放疗、化疗及免疫疗法,以提高疗效。那些未经治疗的胃癌,其诊断后的平均生存期仅为1年左右。
A survey shows that the incidence of gastric cancer worldwide 13.86 / 100,000, second only to lung cancer ranks second. China is a high incidence of gastric cancer. The incidence of gastric cancer in 2009 was 36.21 / 100,000 in the national cancer registration area, 2.6 times that of the world level. Currently, surgery is the only possible cure for gastric cancer. Surgery should be performed as long as the patient's general condition permits and there is no clear distant metastasis. For advanced gastric cancer, because of its high recurrence rate and metastasis rate, it must be actively supplemented with preoperative and postoperative radiotherapy, chemotherapy and immunotherapy to improve the curative effect. Those with untreated gastric cancer, the average survival time after diagnosis is only about 1 year.
