Gastric cancer represents a serious health problem on a global scale. It is the second leading cause of cancer-related death worldwide. Novel therapeutic targets are desperately needed because the meager improvement in the cure rate of about 10% realized by adjunctive treatments to surgery is unacceptable as > 50% patients with localized gastric cancer succumb to their disease. Either postoperative chemoradiotherapy (United States), pre-and post-operative chemotherapy (Europe), and adjuvant chemotherapy after a D2 resection (Asia) can all be regarded as standards of care in the localized gastric cancer management. In metastatic disease the addition of trastuzumab to chemotherapy is standard of care in Her2 positive disease. In the HER2 negative population, the treatments remain limited. In the first line setting, the standard of care is a combination of fluoropyrimidine and platinum containing chemotherapy, with or without epirubicin or docetaxel. The results of targeted therapy trials have by and large been disappointing, but none of these trials looked at an appropriately enriched population. Finally there is a meager overall survival benefit in treating patients with metastatic disease in the second line setting, with either irinotecan, docetaxel or ramucirumab however none of these drugs have been compared head to head in a well-powered randomized controlled trial.
胃癌是全球范围内严重的健康问题。它是全球癌症相关死亡的第二大主要原因。由于手术辅助治疗使治愈率仅提高约10%,这一微小改善无法令人接受,因为超过50%的局限性胃癌患者死于该病,因此迫切需要新的治疗靶点。术后放化疗(美国)、术前和术后化疗(欧洲)以及D2切除术后辅助化疗(亚洲)均可视为局限性胃癌治疗的标准。在转移性疾病中,化疗联合曲妥珠单抗是HER2阳性疾病的标准治疗方法。在HER2阴性人群中,治疗方法仍然有限。在一线治疗中,标准治疗方法是含氟嘧啶和铂类化疗联合或不联合表柔比星或多西他赛。靶向治疗试验的结果总体上令人失望,但这些试验均未针对适当富集的人群。最后,在二线治疗中,使用伊立替康、多西他赛或雷莫西尤单抗治疗转移性疾病患者的总生存获益甚微,然而在一项有力的随机对照试验中,这些药物均未进行直接比较。
