[Metastatic characteristics of cancer of the lower 1/3 of the esophagus].
Extensive metastatic proliferation is rather characteristic of cancer of the lower esophagus. In persons who died due to progression of the disease metastases are revealed in 3 of 4 cases, lymphogenic metastases prevailing over hematogenic ones in the ratio of 3 : 2. Clinical investigations indicate early metastases in cancer of the lower esophagus, intraoperatively these are detected in a half of all the cases, in radical surgery--in 41.3%, in tentative surgery--in 72.8%. Unresectable metastases as frequently as tumor invasion of the adjacent organs are the cause why the radical operation was refused (1 : 1). Intraoperative diagnosis of metastatic dissemination of cancer of the lower esophagus is far from being perfect, which is evidenced by not infrequent detection at autopsy of unremoved metastases in persons, died within the terms up to 3 months following radical surgery (16.8%). Among persons, died after the resection of distal esophageal segments with the construction of esophagastroanastomosis, metastases in the pleural cavity are detected in every fifth person (21.7%), among those died following the Torek surgery--twice as frequent. Among patients who died during the period of 3 months after radiation therapy for cancer of the lower esophagus metastases in lymph nodes and abdominal organs, i.e. beyond the zone of radiation effect, were found in a half of cases.
