食管癌术前放化疗临床研究进展

Pre-operative Chemoradiotherapy for Esophageal Carcinoma

  • 摘要: 手术治疗是可切除食管癌的标准治疗方案,但对局部晚期食管癌,同步放化疗显示了良好的疗效。但是同步放化疗治疗食管癌存在较多的局部区域复发,影响了患者的生活质量。多个大型前瞻性随机分组研究提示,无论是食管鳞状细胞癌还是腺癌,联合应用同步放化疗及手术治疗有望进一步提高患者生存质量,延长患者的生存期。目前常用的同步化疗方案为顺铂及氟尿嘧啶方案,而放疗剂量及靶区不一。研究显示同步放化疗后病理例完全缓解者生存率明显提高,因而疗前预测食管癌患者同步放化疗的敏感性具有重要的地位,可以选择对放化疗抗拒的食管癌患者直接接受手术治疗,避免同步放化疗的不良反应及治疗时机的延搁。目前的常规临床检查手段难以预测及早期判别同步放化疗的疗效,联合应用分子生物标记物有望选择放化疗敏感的患者接受术前放化疗,而对放化疗不敏感的患者则直接接受手术治疗,从而实现食管癌患者的个体化治疗。

     

    Abstract: Surgical resection is the standard treatment and therapy for patients with resectable esophageal carcino-ma. However, in locally advanced esophageal carcinoma, concurrent chemoradiotherapy demonstrates promising out-comes, but the local regional recurrence is more frequent, which severely compromises patients’quality of life. Many pro-spective randomized studies have suggested that, whether in esophageal adenocarcinoma or in esophageal squamous cell carcinoma, a combination of chemoradiotherapy together with surgery could improve the patients’quality of life and prolong overall survival. The commonly used chemotherapy regimen is a combination of cisplatin and fluorouracil, however, the radiation dose and radiation target varies. It is demonstrated that pathologically complete remission, after being given these therapies concurrently, can prolong survival. It is very important to predict the sensitivity to concurrent chemoradio -therapy before treatment. Patients with a disease resistant to chemoradiotherapy can then be selected for surgery resection directly, so as to avoid the toxicities of concurrent chemoradiotherapy and the delay of surgery resection. At present, it is difficult to predict or identify the early treatment outcomes of concurrent chemoradiotherapy. The combined utilization of molecular biomarkers is promising to identify patients with a disease sensitive to chemoradiotherapy for neoadjuvant treat-ment, and to identify patients with a disease resistant to chemoradiotherapy for surgery resection directly. In this way, indi-vidualized treatment strategies could be applied to patients with esophageal carcinoma.
