American Association for Cancer Research: potential target antigens for cancer immunotherapy. April 1-5, 2000, San Francisco, CA, USA.

The 91st annual meeting of the American Association for Cancer Research (AACR) convened this year in San Francisco, USA. Nearly 5600 abstracts were published within ten broad research categories ranging from basic molecular, cellular and pharmaceutical research to cancer epidemiology and prevention. The largest number of poster presentations belonged in the 'Pharmacological and Experimental Therapeutics' section, followed closely by 'Molecular Biology' and 'Cell and Tumour Biology'. Novel tumour antigens and their potential application in cancer immunotherapy were displayed primarily in a section categorised as 'Immunology/Preclinical and Clinical'. This article reports some of the significant tumour antigen-related studies presented at this meeting.
