Histologic prognostic indicators in hepatocellular carcinoma.
Survival and histologic features were studied in 80 patients with proven hepatocellular carcinoma (HCC). The overall survival was 50% at 3.5 weeks with a statistically significant drop in mortality rate after 8.5 weeks. Patients with diffuse clear-cell pattern, focal clear-cell pattern, and no clear cells in their tumors had a 50% survival rate at 14 weeks, 6 weeks, and 3 weeks respectively; the differences in survival rates were statistically significant between any pair (p less than 0.001). No correlation was found between survival and (1) cytologic differentiation, (2) histologic architecture, (3) degree of pleomorphism, or (4) presence of bile production, proteinaceous secretion, giant cells, or cytoplasmic hyaline bodies. Eosinophilic HCC with lamellar fibrosis was not observed in any of our materials. We concluded that the presence of clear cells was the only histologic feature of prognostic significance in our patients.
