Recent trends in histological pattern of cervical carcinoma among three ethnic groups in Malaysia.

Abstract

To study the trend of different histological types of cervical carcinoma among the 3 major ethnic groups in Malaysia. All invasive cervical carcinoma histologically diagnosed for the first time in 1991-1992 and 1996-1997 at the University Hospital, Kuala Lumpur (UHKL) were reviewed for the following parameters; age, ethnic group, histological category. One hundred and twenty-one and 145 cases were diagnosed in 1991-1992 and 1996-1997, respectively. During both periods, squamous was followed by adeno and adenosquamous carcinoma in frequency. Patients' mean ages ranged within the 4th decade for all 3 major histological types. Ethnically, an overall predilection for the Chinese was observed. While squamous carcinomas had declined among the Chinese and Malays, adenocarcinomas were noted to increase. The converse was observed among the Indians. Ethnically, cervical carcinoma showed a predilection for Malaysians of Chinese descent. A decreasing incidence of squamous with a worrying increasing trend of adenocarcinoma was observed, like in other populations studied.
