This study proposes to describe and evaluate the rate of spontaneous regression of CIN2 at 2 year of follow up in women between 18 and 39 year old. This follow-up is proposed as an alternative to the treatment of reference (conization) with a possible extension to 4 years


The INCa recommendations of December 2016 propose the destruction or abstention-monitoring of high-grade histological cervical lesions (HSIL) as an alternative to conization under certain conditions. These are women under 30 years old, with a small lesion in colposcopy, without any sign of invasion, with a squamocolumnar junction seen. These women must accept the principle of regular monitoring by cytology and colposcopy +/- biopsy every 6 months for a maximum of 2 years. HSIL group 2 histological entities CIN2 and CIN3. It is recognized that CIN2 are associated with CIN1 and CIN3 biology whose diagnosis is the result of the subjectivity of colposcopy allowing cervical biopsy and the variability of pathological interpretation due to poor reproducibility of histological diagnosis. CIN2 regress spontaneously in more than 50% of cases at 1 year, either completely (no lesion) or partially (LSIL low grade lesions). No invasive lesions are diagnosed over 2-year observation periods. Among the clinical, pathological and virological criteria, only the initial HPV genotyping seems to have a prognostic influence. There is therefore no strong scientific argument for routine conization in a woman over 30 years of age with a CIN2 lesion extended over more than two quadrants. In addition, conization is associated with an obstetrical risk (prematurity) and post-therapeutic colposcopic cervical stenosis complicates subsequent monitoring in case of abnormal smears. These considerations encourage the extension of the indications of abstention monitoring in the management of women with CIN2 wishing to procreate with an extension of the age to 39 year old, with no limit of size of the lesion and to satisfactory colposcopy

Termination of all transmission of infection by global extermination of the infectious agent through surveillance and containment (From Porta, A Dictionary of Epidemiology, 5th ed).

Inflammation of the meninges caused by LISTERIA MONOCYTOGENES infection, usually occurring in individuals under the age of 3 years or over the age of 50 years. It may occur at any age in individuals with IMMUNOLOGIC DEFICIENCY SYNDROMES. Clinical manifestations include FEVER, altered mentation, HEADACHE, meningeal signs, focal neurologic signs, and SEIZURES. (From Medicine 1998 Sep;77(5):313-36)

Programs of disease surveillance, generally within health care facilities, designed to investigate, prevent, and control the spread of infections and their causative microorganisms.

A rare, slowly progressive encephalitis caused by chronic infection with the MEASLES VIRUS. The condition occurs primarily in children and young adults, approximately 2-8 years after the initial infection. A gradual decline in intellectual abilities and behavioral alterations are followed by progressive MYOCLONUS; MUSCLE SPASTICITY; SEIZURES; DEMENTIA; autonomic dysfunction; and ATAXIA. DEATH usually occurs 1-3 years after disease onset. Pathologic features include perivascular cuffing, eosinophilic cytoplasmic inclusions, neurophagia, and fibrous gliosis. It is caused by the SSPE virus, which is a defective variant of MEASLES VIRUS. (From Adams et al., Principles of Neurology, 6th ed, pp767-8)
