直肠癌侧方淋巴结清扫的个性化治疗策略

The individualized strategy for lateral pelvic lymph node dissection in advanced rectal cancer

摘要:

随着全直肠系膜切除术和新辅助放化疗的广泛应用,中低位直肠癌患者的预后明显改善。近年来随着腹腔镜和机器人手术系统等微创技术应用于直肠癌根治性手术,以及肿瘤分子标志物和基因测序技术的发展,直肠癌治疗已进入个体化精准医疗时代。在这样的时代背景下,关于中低位直肠癌侧方淋巴结清扫必要性的争议愈发引人注目,其包括与新辅助治疗的关系,侧方淋巴结清扫的手术指征、范围及神经保护等多个方面。作为进展期中低位直肠癌重要治疗手段,直面争议,增加侧方淋巴结清扫相关循证医学证据是当务之急。

Recently, with the development and widespread application of total mesorectal excision and neoadjuvant chemoradiotherapy, the long-term overall survival and disease-free survival of patients with middle & low rectal cancer have been greatly improved. Moreover, there are also researches in minimally invasive techniques, such as laparoscopy and robotic surgical system in the radical rectal surgery, as well as the combination of tumor molecular targeting markers and gene sequencing technology. Nowadays, the treatment of rectal cancer has entered a new era of individualized precise medicine. However, there are still some controversies in lateral lymph node dissection. The criteria of diagnosis and treatment, neoadjuvant therapy, indications of lateral lymph node dissection, the area of dissection and neuroprotection are still unsatisfactory. It is necessary to explore the personalized treatment strategies of lateral lymph node dissection in the precise medical era.
