Ten cases of surgically resected pulmonary metastases arising from colorectal cancer were analyzed. Five year survival rate of these patients was 14%. Only one patient survived more than five years, whose primary and metastatic lesions were not so progressive without lymph node metastasis. The rate of regional lymph node metastasis was 25% and the patients with positive nodes died or had recurrence within 2 years. Serum CEA level was useful as a tumor marker and high-level of serum CEA after operation suggested remnant disease.
分析了10例经手术切除的结直肠癌肺转移病例。这些患者的5年生存率为14%。只有1例患者存活超过5年，其原发灶和转移灶进展不明显且无淋巴结转移。区域淋巴结转移率为25%，有阳性淋巴结的患者在2年内死亡或复发。血清癌胚抗原（CEA）水平作为一种肿瘤标志物很有用，术后血清CEA水平高提示有残留病灶。
