In our study population, 21.8% had fatty liver diagnosed by USG, 9.3% were non-alcoholic with fatty liver, and 4.1% were non-alcoholic and non-overweight with fatty liver. Our results suggest that central body fat distribution can correlate with the development of fatty liver, and that measurement of percentage body fat is useful to assess the etiology of fatty liver in non-alcoholic and non-overweight participants, particularly women.

Spontaneous regression of hepatocellular carcinoma is a rare phenomenon. Abscopal regression of tumours resulting from the eVect of irradiation of a tissue on a remote non-irradiated tissue is also rare. The case of a 76 year old Japanese man with hepatocellular carcinoma that regressed after radiotherapy for thoracic vertebral bone metastasis is described. Serum levels of tumour necrosis factorincreased after radiotherapy. The findings suggests that such abscopal related regression may be associated with host immune response, involving cytokines such as tumour necrosis factor-. (Gut 1998;43:575-577)
