Primary hepatocellular carcinoma in the Asian Pacific region.

This survey was conducted to obtain current data relating to the epidemiology, aetiological factors, diagnostic tests in use, effect of various treatments and the evaluation of the extent of any population screening procedures. From replies to questionnaires sent to countries in West, South, North, South East Asian and Oceania the data showed that Primary Hepatocellular Carcinoma is common in most areas, but has a lower incidence amongst the non useful method of diagnosis. New biochemical and immunological markers are being studied. Untreated disease seldom survived more than 3 months. Various treatment protocols are being done since about 85% of tumours are non resectible at presentation. A population screening is done in China and on a risk groups in Taiwan and Singapore.
