Incidence, etiologic aspects and clinicopathologic features in intrahepatic cholangiocellular carcinoma : A study of 51 cases from a low-endemicity area.
A total of 51 cases (19 males and 32 females) of intrahepatic cholangiocellular carcinoma (CCC) from a low-endemicity area of primary liver cancer was analyzed during the periods from 1958 to 1979 and from 1984 to 1991.
The mean annual age-adjusted incidence rate was 0.44 for males and 0.56 for females per 100000 inhabitants.
CCC was diagnosed before death in only 31%. There was a female predominance in patients over 70 years of age (p<0.05).
At presentation, malaise (85%), weight loss (73%), abdominal pain (50%) and hepatomegaly (80%) were common.
The median survival time from diagnosis was 2 months.
The mean age at the time of death was 72 years (range 41-92).
At autopsy, cholelithiasis was found in 61% (81% in patients older than 70 years) and cirrhosis in 30% of patients.
Cholelithiasis was more common in CCC (p<0.01) than in hepatocellular carcinoma cases with the same mean age.
Not one case of inflammatory bowel disease was found.
The gross appearance of the tumor was predominantly massive (49%) or multinodular (35%). The most common histological features were tubular pattern of growth (82%) and abundant fibrous stroma.
Metastases were particularly associated with the lymph nodes (41%), skeleton (26%) and lungs (16%).
