乳癌常转移至食管。Abrams 等解剖167例乳癌,发现4.2%伴食管转移。但 Holyoke 等发现所有乳癌病例中仅0.4%有明显的吞咽困难。作者于1987年收治一进行性吞咽困难的女性患者(68岁)。1968年曾因低分化左侧乳癌(pT_1M_0N_0)行癌根治术加放疗。1985年起渐感吞咽困难。内镜及 X 线检查显示食管中段向心性狭窄,但无恶性征象。全身系统检查未发现肿瘤或转移灶。遂行内镜下食管扩张治疗,术后症状持续加重。再次 Breast cancer often metastasizes to the esophagus. Abrams dissected 167 cases of breast cancer and found that 4.2% had esophageal metastases. However, Holyoke et al. found that only 0.4% of all breast cancer cases had significant dysphagia. The authors treated a female patient with progressive dysphagia (68 years old) in 1987. In 1968, he had undergone cancer radical surgery plus radiotherapy for poorly differentiated left breast cancer (pT_1M_0N_0). Difficult to swallow since 1985. Endoscopy and X-ray examination showed a narrow concentric esophagus but no signs of malignancy. Systemic examination revealed no tumors or metastases. Underwent endoscopic esophageal dilatation therapy, and symptoms continued to increase after surgery. once again
