Multizonal intraepithelial neoplasia of the lower genital tract and anus in women: terminology for defining the disease, an introduction by the British Society for Colposcopy and Cervical Pathology (BSCCP), International Anal Neoplasia Society (IANS), European Federation for Colposcopy (EFC) and British Society for the Study of Vulval Disease (BSSVD) scientific committees

Abstract

Abstract Multizonal anogenital intraepithelial neoplasia (MZIN) is an uncommon chronic pre-malignant condition. In the United Kingdom (UK) and elsewhere MZIN is managed by a variety of clinical specialities with differing strategies, resulting in a lack of standardisation in diagnosis and treatment which ultimately disadvantages those affected. Screening for anogenital precancerous conditions is sporadic rather than nationalised in the UK and elsewhere in Europe, with the exception of the cervix. To address this lack of standardisation, the BSCCP brought together a panel of stakeholders from aligned expert society committees (IANS, EFC and BSSVD) to review existing evidence and provide a framework for national UK guidelines. Here, we define terminology and scope, as a platform for subsequent guideline development and guide further research. We define MZIN as Human Papillomavirus (HPV)-related squamous intraepithelial lesions occurring in two or more anogenital regions. People with MZIN are a high-risk group for anogenital cancers and subsequently may require tailored monitoring in specialist multi-disciplinary clinics. Centralisation of care and education for primary care providers may improve management. The development of guidelines which incorporate all clinical stakeholders are now needed to provide an international framework regarding the screening, diagnosis, treatment and future prevention of MZIN.
