Abstract :Due to the general tendency of postponing the reproductive stage to superior ages and the effect
that it has more than enough this phenomenon have the techniques of attended reproduction, the
cancer coincidence and pregnancy is supposing an increment, as well as of its precursors lesions. It
was carried out a prospective descriptive study to determine the statistical relationship between the
progression of epithelial cervical lesions and clinical-epidemic factors of interest in the 131 pregnant
assisted in the General Educational Hospital “Baire ‘Hero” during the period 2014-2017. 61% of the
patients were 20-29 years of age old, 42% antecedent referred 1-2 childbirths y/o abortions, 74% use
of intra-uterine devices, 37% precocious menarquia before 13 years of age, 32% began the sexual
relationships before the 15 years and the negative cytology or with lesions of low degree it was
present in 71% of the studied sample. The histology of CIN2+, lesion in cervical channel, +2 sexual
couples in last 5 years, lesion >149 mm2
, persistent VPH infection, age smaller than 20 years, lesion
in anterior lip or both lips and corners, cytology with HSIL/cancer, parity >1, abortions >2 and the
first sexual relationship before 15 years of age showed significant statistical difference among the
cases in that it was identified or non-progression of the epithelial lesions. The presence of CIN2+,
lesion in cervical channel, lesion >149 mm2
, persistent IVPH and age smaller than 20 years meant a
probability of progression of 93%.
