Abstract：
A 60-year-old man diagnosed with sigmoid colon cancer was admitted to our hospital. A CT scan revealed multiple liver metastases. The patient was administered 15 courses of FOLFIRI chemotherapy and 15 courses of FOLFIRI plus Cmab chemotherapy. After this treatment, multiple liver metastases disappeared, and laparoscopic resection of the sigmoid colon was performed. Two months later, a recurrent lesion was found in the liver segment(S1), and 5 courses of FOLFIRI plus Cmab chemotherapy were performed. Although the CEA level decreased, the tumor size remained unchanged. Therefore, partial resection of the liver was performed, followed by 18 courses of FOLFIRI chemotherapy. After that, the patient was followed for a year without chemotherapy. However, about 1 year later, recurrence was observed in liver segments S5 and S6. A right lobectomy was performed for these 2 lesions, and then 16 more courses of FOLFIRI chemotherapy were performed. The chemotherapy was discontinued, and the patient was then followed up as an outpatient without chemotherapy; there has been no recurrence.
摘要：
一名被诊断为乙状结肠癌的60岁男子被送往我们医院。CT扫描显示多发肝转移。患者接受15个疗程的FOLFIRI化疗和15个疗程的FOLFIRI加Cmab化疗。经过这种治疗,多发性肝转移消失,并进行腹腔镜乙状结肠切除术。两个月后,在肝段（S1）发现复发性病变，并进行了5个疗程的FOLFIRI加Cmab化疗。虽然CEA水平有所下降,肿瘤大小保持不变。因此,进行了肝脏部分切除术，随后18个疗程的FOLFIRI化疗。之后,患者在没有化疗的情况下随访了一年.然而,大约一年后，在肝段S5和S6中观察到复发。对这2个病灶进行了右叶切除术,然后再进行16个疗程的FOLFIRI化疗。化疗停止了,然后患者在没有化疗的情况下作为门诊患者进行随访;没有复发。
