title: The clinical characteristics of patients with synchronous squamous cell carcinoma of the esophagus and hepatocellular carcinoma.
abstract: An ongoing analysis of 762 patients with esophageal cancer revealed 4 (0.52%) male patients with synchronous hepatocellular carcinoma (HCC). A long history of habitual alcohol intake and heavy cigarette smoking was recognized in all four patients and, therefore, the possibility of these two factors being independent risk factors for this double cancer was suggested. Palliative treatment was undertaken since either one or both cancers were too far advanced, or because liver function was poor even in those patients with resectable cancers. The prognosis correlated more closely to the TNM stage of esophageal cancer rather than the HCC and the causes of death were related to the esophageal cancer in all four patients. These findings suggest that, in patients with this combination of double cancer, the state of the esophageal cancer may be a more reliable prognostic factor than that of the HCC and thus, the curability of esophageal cancer is of primary importance.
