The prognostic influence on the DNA content was investigated in 189 patients (esophagus carcinoma n = 45, gastric cancer n = 103, pancreatic cancer n = 41) who underwent a curative resection. In a multivariate analysis the DNA content had a strong as well as an independent influence on the prognosis in esophagus cancer and in pancreatic carcinoma. In gastric cancer, the DNA content had no influence on the prognosis. These results show that the DNA content of the tumor cells, as a measurement of the numerous chromosomal aberrations, well reflects the aggressiveness of the tumor growth in esophagus- and pancreatic cancer. In these tumors it represents the decisive criteria for the prognostic judgement.

Frequently when dysphagia first becomes manifest, esophageal carcinoma is already unresectable. Endoscopic laser therapy is a recently introduced method which can be used for the palliative treatment of esophageal cancer. By using the method the tumour is destroyed and the esophagus is recanalized, there is low incidence of complications, and the patient can be fed naturally thus improving quality of life. The method has been perfected over the past years and now offers excellent results.
