Introduction:The objective of the study was to determine the trends of cancer cervix in Karachi South during an eight (1995-2002) year period. Methododology: Cancer cervix cases recorded at Karachi Cancer Registry during 1st January 1995 to 31st December 2002 were analyzed. Trends were studied by analyzing the age standardized incidence rates (ASR)s in 2 time periods, 1995-97 and 1998-2002.
Cancer cervix ranked sixth in the 1995-97 period the age standardized incidence rate (ASR) world and crude incidence rate (CIR) per 100,000 were 6.81 and 3.22. It reached the fifth ranking in the 1998-2002 period with an ASR and CIR of 7.5 and 4.0 per 100,000. Thus between 1995 and 2002, the incidence of cervical cancer registered an approximate 10% increase. The mean age of the cancer cases was 53.3 years (SD 11.6, 95% CI 50.58, 55.96, range 32-85 years) and 50.7 years (SD 11.7, 95% CI 48.8, 52.5, range 51 years) in period 1 and 2 respectively. The morphological components of squamous cell carcinoma and adenocarcinoma remained stable during this period, though a marginally higher component and increasing incidence of adenocarcinoma was observed throughout. A negligible down staging was observed in the 1998-2002 period. Localized malignancy was observed in 30.8% in period 2 as compared to 25.7% in period 1 and the component of carcinoma in situ increased from 0% percent in period 1 to 1.3% in the second period. Despite this two thirds of the cases still presented with a regional or distant spread of disease.
Pakistan at present falls into a low risk cancer cervix region. The cause of concern is the steadily increasing incidence especially in the younger birth cohorts, the advanced disease at presentation, insignificant in-situ cancers and no preventive intervention or awareness practices in place.
