Diagnosis and treatment of superficial oesophageal carcinoma.
Oesophageal carcinoma is a major cause of cancer death in certain parts of the world. Early detection provides the only chance of cure. In this study, one female and nine male patients with superficial oesophageal carcinoma were investigated to determine the pertinent clinical and pathological features. All male patients were smokers and six patients drank various amounts of alcohol on a daily basis. Histologically, five cases were confined within the mucosal layer and five within the submucosal layer. All five mucosal cancer cases and two of the five submucosal cancer cases were asymptomatic. Endoscopically, all five mucosal cancer patients had flat lesions, whereas the five submucosal cancer tumours appeared either protruding or depressed. Barium oesophagography failed to demonstrate the lesions in four of five mucosal cancer and one of five submucosal cancer cases. Endoscopic ultrasonography correctly detected the depth of cancer invasion in six out of eight superficial oesophageal carcinoma cases. All patients received a one-stage operation that included oesophagectomy and lymph node dissection. All five mucosal cancer patients had no lymph node involvement and have experienced no tumour recurrence. Among them, one who had concomitant hepatocellular carcinoma died early. Of the five submucosal cancer cases, four died 1-5 years after the operation. It is concluded that oesophageal carcinoma is curable in its early stage. Physicians should be alert while performing endoscopic examination. We believe that the dyeing technique is a useful adjunct to endoscopic examination.
