目的:探讨食管癌肉瘤的病理特征、临床特点和治疗方法。方法:对7例食管癌肉瘤患者的临床表现、术前影像学、内窥镜资料、外科治疗结果进行回顾性分析。结果:食管癌肉瘤患者的主要临床症状为逐渐加重的下咽不顺,平均病程4.1个月。好发于食管中段。多为息肉样腔内生长,有短蒂和食管壁相连,个别呈浸润生长。全组7例均行食管部分切除,无手术死亡及并发症。光镜下癌和肉瘤两种成分共存,腔内型者瘤体多以肉瘤成分为主,癌多局限于蒂的基底部粘膜。全组术后随访6例,均健在。结论:食管癌肉瘤是一种侵袭性差,淋巴结转移率低,预后较好的肿瘤。手术切除是其主要的治疗方法。
Objective: To investigate the pathological features, clinical features and treatment of esophageal sarcoma. Methods: The clinical manifestations, preoperative imaging, endoscopic data and surgical treatment of 7 patients with esophageal sarcoma were analyzed retrospectively. Results: The main clinical symptoms of esophageal carcinosarcoma patients with gradual pharyngeal obstruction, the average duration of 4.1 months. Occur in the middle of the esophagus. Multi-polyp-like cavity growth, short pedicel and esophageal wall were connected, were infiltration of individual growth. The whole group of 7 patients underwent esophagectomy, without surgical death and complications. Light microscopic cancer and sarcoma two components coexist, endometrial tumor mostly sarcoma, cancerous and more limited to pedicle basal mucosa. The whole group were followed up in 6 cases, all alive. Conclusion: Esophageal sarcoma is a poorly invasive, low rate of lymph node metastasis, a better prognosis of the tumor. Surgical resection is its main treatment.
