Er. Lemmer et al., Surgical resection for hepatocellular carcinoma in Cape Town - A clinical and histopathological study, S AFR MED J, 88(12), 1998, pp. 1575-1580
Objective. Review of surgical resections performed for hepatocellular carci
noma (HCC) at our institution between 1990 and 1996, histology of resected
specimens, and clinical outcome.
Design. Retrospective and prospective study of 14 patients who underwent re
section for HCC.
Setting. The Hepatobiliary Unit and Liver Clinic, Groote Schuur Hospital, C
ape Town.
Patients. Fourteen patients who underwent Liver resections for HCC.
Interventions. Hepatic resections using prolonged vascular inflow occlusion
.
Outcome measures. Clinical outcome and disease-free survival following rese
ction.
Results. Fourteen patients (5.6% of the total number presenting with HCC) u
nderwent liver resection for HCC at our institution between 1990 and 1996.
There were 7 men, median age 40 years (range 18 - 74 years). Only 2 patient
s were black, and only 1 of these patients had evidence of hepatitis B viru
s (HBV) infection in the liver. Extensive live; resections were often requi
red. The mean (SD) ischaemic time was 81 (26) minutes and mean estimated bl
ood loss was 938 (649) ml. During hospital admission, 1 patient developed a
minor bile leak that settled spontaneously, and 1 patient suffered a strok
e and died. The mean hospital stay following operation was 12 days (range 7
- 21 days). Disease-free patient survival at 1, 2 and 3 years was 85%, 75%
,and 62%, respectively. Histopathology of the resected specimens showed tha
t 10 of 14 tumours had arisen in non-cirrhotic livers. Mean tumour size was
10.6 (4.6) cm. Only 1 specimen showed thr fibrolamellar variant of HCC.
Conclusions. Only a small proportion of patients with HCC seen at Groote Sc
huur Hospital were eligible for resection, and only a:minority of these had
HBV-associated 'African' HCC. The results of hepatic resection at our inst
itution compare favourably with literature reports, despite the relatively
large size of the tumours. It is of interest that most tumours arose in non
-cirrhotic livers. There was no evidence of proliferation of 'oval-like' ce
lls in non-neoplastic liver tissue.
