In sub-Saharan Africa, invasive cervical cancer (ICC) incidence and mortality are among the highest in the world. This crosssectional epidemiological study assessed human papillomavirus (HPV) prevalence and type distribution in women with ICC in Ghana, Nigeria, and South Africa. Cervical biopsy specimens were obtained from women aged 21 years with lesions clinically suggestive of ICC. Histopathological diagnosis of ICC was determined by light microscopy examination of hematoxylin and eosin stained sections of paraffin-embedded cervical specimens; samples with a confirmed histopathological diagnosis underwent HPV DNA testing by polymerase chain reaction. HPV-positive specimens were typed by reverse hybridization line probe assay. Between October 2007 and March 2010, cervical specimens from 659 women were collected (167 in Ghana, 192 in Nigeria and 300 in South Africa); 570 cases were histologically confirmed as ICC. The tumor type was identified in 551=570 women with ICC; squamous cell carcinoma was observed in 476=570 (83.5%) cases.

Objectives To document the frequency of pathology in women who complain of postcoital bleeding. To determine whether negative cervical cytology excludes serious pathology in women with postcoital bleeding. To determine whether postcoital bleeding increases the risk of serious pathology in women with an abnormal smear.Design A retrospective study.Setting A university teaching hospital. Population 314 women with postcoital bleeding seen in the gynaecology service from ®rst January 1988 to 31 December 1994. Methods Women were identi®ed from the computerised records of the colposcopy service and copies of correspondence, which was routinely retained on computer. The latter was searched for the text strings coital and intercourse. Main outcome measure Histopathological diagnosis.Results Twelve women (4%) had invasive cancer: 10 were cervical or vaginal cancers and two endometrial cancers. Eight of the 10 cervical or vaginal cancers were clinically apparent. Four women of these 10 had had a normal smear before being referred for further investigation of postcoital bleeding. Two of these cancers were visible only with the aid of the colposcope. Thus, 0.6% of women attending a gynaecology service with postcoital bleeding, a normal looking cervix and a normal smear had invasive cancer of the cervix. Cervical intraepithelial neoplasia were found in 54 women (17.%) and 15 women (5%) had cervical polyps. Nineteen of the 63 women (30%) with signi®cant pathology had a normal or in¯ammatory cervical smear. No explanation for the postcoital bleeding was found in 155 women (49 %).Conclusions Although invasive cancer is rare in women with postcoital bleeding, it is much commoner than in the general population. It seems likely that cervical intraepithelial neoplasia is also associated with postcoital bleeding, perhaps because the fragile cervical epithelium becomes detached during intercourse. Postcoital bleeding should continue to be regarded as an indication of high risk for invasive cervical cancer and for cervical intraepithelial neoplasia. Prompt referral to a colposcopy clinic is indicated, but most women with postcoital bleeding will have no serious abnormality.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
