Abstract
An expanded cohort study of 74,828 benzene-exposed and 35,805 unexpose d workers were followed during 1972 to 1987, based on a previous study in 12 cities in China. A small increase was observed in total cancer mortality among benzene-exposed compared with unexposed workers (relat ive risk [RR]=1.2). Statistically significant excesses were noted for leukemia (RR=2.3), malignant lymphoma (RR=4.5), and lung cancer (RR=1. 4). When risks were evaluated by leukemia subtype, only acute myelogen ous leukemia was significantly elevated (RR=3.1), although nonsignific ant excesses were also noted for chronic myelogenous leukemia (RR=2.6) and acute lymphocytic leukemia (RR=2.3). A significant excess was als o found for aplastic anemia.
