Improving cervical cancer screening in Ghana using biomarkers
Ama Afrah
University of Ghana, Ghana
S
creening and management of abnormal cytology has resulted in a marked reduction in invasive cervical cancer using
Pap smear. However many women screened are not found to have significant precursor lesions. This is due to the poor
specificity of high-risk human papillomavirus triage. More specific cervical cancer biomarkers may be more effective triage
tools. Molecular markers have been extensively investigated with a view to providing early and accurate information on and
prediction of response to treatment of early cervical cancer. Proliferation is a key feature of the progression of tumors and is
now widely estimated by the immunocytochemical assessment of the nuclear antigen Ki-67. The proliferative rate determined
with Ki-67 antibody may provide information regarding cell kinetics of cervical carcinoma and their precursor lesions with
high rate of cell proliferation, potentially useful in identifying patients in order to improve the therapeutic approach, by a rapid,
practical and easily performed immunocytochemicalmethod. p16 on the other hand is alsowidely used as immunocytochemical
marker in gynecologic pathology and for that matter Pap smears. Strong and diffuse cytoplasmic and nuclear expression of p16
in squamous cell carcinoma of the female genital tract is strongly associated with high-risk human papilloma virus infection
and neoplasms of cervical origin. The majority of squamous cell carcinomas of uterine cervix express p16. This study will
evaluate whether a dual stain for p16 and Ki-67 may improve the triage of abnormal Pap smears.
