Frequency and significance of tumor thrombi in esophageal varices in hepatocellular carcinoma associated with cirrhosis.

Histological examination of the wall of the stomach and esophagus in patients with hepatocellular carcinoma associated with cirrhosis demonstrated intravariceal tumor thrombi in 13 (23.6%) of 55 cases studied. There were distant hematogenous metastases in 31 of them, of whom 12 (38.7%) had variceal tumor thrombi. Tumor thrombi were of varying sizes, and tumor cells appeared either intact, degenerated or necrotic. In seven cases, there was a firm adhesion of thrombi onto the vascular wall suggesting possible mural infiltration, but no extravascular metastases were noted grossly. These findings suggest a possibility of metastasis of hepatocellular carcinoma to the stomach and esophagus via the portal vein. It is also suggested that the degree of varices is not increased by tumor thrombus formation per se, and that both varices and tumor thrombi are due to extensive hepatofugal collateral circulation. Considering that 12 of 13 cases of intravariceal tumor thrombi had lung metastases, a portal vein-varices-lung route is possible for lung metastasis beside the established route through the hepatic vein in hepatocellular carcinoma.

Relationship between the degree of injury at operation and the change in antimyosin antibody titer in the postpericardiotomy syndrome.

Successive measurements of cardiac myosin light chain I (MLC), creatine kinase isoenzyme MB (CKMB), and the titer of antimyosin antibody (AMA) were performed prospectively in 19 patients following open heart surgery. Seven of these patients showed the postpericardiotomy syndrome (PPS). No differences in serum concentrations of MLC or CKMB were observed between the patients with and without PPS, and all patients in both groups had abnormal MLC values after surgery. However, only patients with PPS had significantly elevated AMA titers. The maximum AMA titer was significantly correlated with the severity of the effusion. These data suggest that PPS is unrelated to the severity of myocardial injury during operation. Furthermore, the AMA titer may be useful as one of the indicators for determining the patient's clinical condition.
