Women received the most benefit as measured by lifetime quality-adjusted life-years (QALY) if they received cytologic testing every 3 years and received repeat testing for ASCUS. The strategy with the lowest cost was cytologic testing every 3 years and hrHPV triage for ASCUS ($1,267), and the strategy of 3-year cytology testing with repeat testing for ASCUS had more QALY but at a higher cost ($2,166).
Out of these 89 patients, nineteen (n=19) had pap smears results of ASCUS. Data from these 19 patients were included in this study (Table 1).
Em levantamento realizado em 32 municipios do estado do Rio de Janeiro entre os anos de 2007 e 2010, pelo SITEC/INCA, foi possivel constatar que as colpocitologias com laudos alterados apresentaram um percentual de diagnosticos ASCUS equivalente a 44,7%.
Patients of ASCUS with HR-HPV infection, low-grade and high-grade squamous intraepithelial lesion were underwent colposcopy.
If the specimen is hrHPV positive and cytology is ASCUS or more worrisome the patient is referred for colposcopy (figure, page 14).
The Pap smear was normal or negative smear in 11.75%, inflammation was reported in 77.5%, ASCUS in 5.5%, ASC-H in 0.25%, AGUS in 0.5%, LSIL in 2%, HSIL in 1.5%, and invasive cancer in 0.5%.
All above mentioned genera are widely used in the experimental class of genetics to study crossing over and gene conversion due to the unique arrangement of ascospores in an ascus as genetic model organisms (Ines et al., 2010).
From each ascoma sample, two microscope slides were prepared and micrographs of ascus and spores contained in 5 randomly selected fields were acquired.
A total of 238 Pap smears were collected among the 75 women in this study group, of which 86% were negative or ASCUS and 13% were LSIL.
Of the 30 ECA (21% of 143 cases), 15 (10.5%) had ASCUS, and 15 had LGSIL (10.5% of 143 cases).
