Abstract: Preliminary results of a study of the possible relationship of depot-medroxy-progesterone acetate (DMPA) to invasive cervical cancer are presented. The findings are based on data from three participating centres in Thailand and one in Mexico. A relative risk for cervical cancer of 1.2 was observed in women who had ever used DMPA; this was not statistically significant. No consistent increase in risk with duration of use was observed, although a relative risk of 2 was found in women who had used DMPA for more than 5 years. This observed increase in risk was confined to women who were aged under 46 years or who had first been exposed to DMPA before 30 years of age. These findings are based on small numbers of subjects, and may not represent a causal relationship.
