Background: ThinPrep® (TP) cervical cytology, as a liquid-based method, has many benefits but also a relatively high unsatisfactory rate due to debris/lubricant contamination and the presence of blood. These contaminants clog the TP filter and prevent the deposition of adequate diagnostic cells on the slide. An acetic acid wash (AAW) protocol is often used to lyse red blood cells, before preparing the TP slides. Design: From 23,291 TP cervical cytology specimens over a 4-month period, 2739 underwent AAW protocol due to initial unsatisfactory smear (UNS) with scant cellularity due to blood or being grossly bloody. Randomly selected 2739 cervical cytology specimens which did not undergo AAW from the same time period formed the control (non-AAW) group. Cytopathologic interpretations of AAW and non-AAW groups were compared using the Chi-square test. Results: About 94.2% of the 2739 cases which underwent AAW were subsequently satisfactory for evaluation with interpretations of atypical squamous cells of undetermined significance (ASCUS) 4.9% (135), low-grade squamous intraepithelial lesions (LSIL) 3.7% (102), and high-grade squamous intraepithelial lesions (HSIL) 1% (28). From the 2739 control cases, 96.3% were satisfactory with ASCUS 5.5% (151), LSIL 5.1% (139), and HSIL 0.7% (19). The prevalence of ASCUS interpretations was similar (P = 0.33). Although there were 32% more HSIL interpretations in the AAW group (28 in AAW vs. 19 in non-AAW), the difference was statistically insignificant (P = 0.18). AAW category; however, had significantly fewer LSIL interpretations (P = 0.02). The percentage of UNS cases remained higher in the AAW group with statistical significance (P < 0.01). Conclusions: While AAW had a significantly higher percent of UNS interpretations, the protocol was effective in rescuing 94.2% of specimens which otherwise may have been reported unsatisfactory. This improved patient care by avoiding a repeat test. The prevalence of ASCUS and HSIL interpretations between AAW and non-AAW groups were comparable. Though not statistically significant, HSIL interpretations were relatively higher in the AAW group. LSIL interpretations showed lower prevalence in AAW group.

The aim of this study was to evaluate retrospectively cytologic screening for cancers and precancerous lesions of the cervix and to research whether biopsy is overused among women with a cytologic diagnosis of atypical squamous cells of undetermined significance (ASCUS). We examined 28 469 smears obtained over 5 years. The patients were referred when the result of the smear was abnormal for a colposcopic biopsy, endocervical curettage, or a repeat Papanicolaou smear. The results of the screening of 28 469 smears are as follows: 699 (2.45%) ASCUS, 67 (0.23%) low-grade squamous intraepithelial lesions (LGSIL), 43 (0.15%) high-grade squamous intraepithelial lesions (HGSIL), 1 epidermoid carcinoma, 31 (0.10%) atypical glandular cells, and 1 adenocarcinoma. Histologic examination of the cervix was done in 119 patients (17.0%) of ASCUS, 13 patients (10.9%) of LGSIL, and 15 patients (12.6%) of HGSIL and cervical carcinoma. In the 119 women with histological examination, histologic examination was generally performed in patients with ASCUS neoplastic Papanicolaou smear, and histologic diagnosis of low-grade, high-grade, or invasive lesion of the cervix was made in 23.5% of women with ASCUS; in these patients, 46.4% were cytologic LGSIL and 53.5 % were cytologic HGSIL and cervical carcinoma. In the aspect of these findings, we concluded that for patients with a cytologic diagnosis of ASCUS, more aggressive interventions should be performed

Objective: The aim of this study was to compare the performance of the current conventional Pap smear with liquid-based cytology (LBC) preparations. Study Design: Women routinely undergoing their cytopathological and histopathological examinations at Fundação Oncocentro de São Paulo (FOSP) were recruited for LBC. Conventional smears were analyzed from women from other areas of the State of São Paulo with similar sociodemographic characteristics. Results: A total of 218,594 cases were analyzed, consisting of 206,999 conventional smears and 11,595 LBC. Among the conventional smears, 3.0% were of unsatisfactory preparation; conversely, unsatisfactory LBC preparations accounted for 0.3%. The ASC-H (atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion) frequency did not demonstrate any differences between the two methods. In contrast, the incidence of ASC-US (atypical squamous cells of undetermined significance) was almost twice as frequent between LBC and conventional smears, at 2.9 versus 1.6%, respectively. An equal percentage of high-grade squamous intraepithelial lesions were observed for the two methods, but not for low-grade squamous intraepithelial lesions, which were more significantly observed in LBC preparations than in conventional smears (2.2 vs. 0.7%). The index of positivity was importantly enhanced from 3.0% (conventional smears) to 5.7% (LBC). Conclusions: LBC performed better than conventional smears, and we are truly confident that LBC can improve public health strategies aimed at reducing cervical lesions through prevention programs.

Objective To evaluate the association of age at first sexual intercourse with the results of the cervicovaginal cytology. Study Design Observational analytical study about the prevalence of altered cervicovaginal cytology results in women aged between 18 and 34 years from a densely populated area in Brazil, during 10 years. The patients were stratified into 2 categories according to their age at first sexual intercourse (13–16 years and 17–24 years). Results From the total of 2,505,154 exams, 898,921 tests were in accordance with the inclusion criteria. Considering women with 4 years or less from the first sexual intercourse as a reference, those with 5 to 9 years and 10 years or more showed a higher prevalence of high-grade squamous intraepithelial lesions (HSILs). Women with an earlier onset of sexual intercourse (13–16 years) showed higher prevalence ratios for atypical squamous cells (ASC), low-grade squamous intraepithelial lesion (LSIL) and HSIL. The prevalence ratio for HSIL adjusted by age at diagnosis and by age at first sexual intercourse was higher only for women with an earlier onset of sexual intercourse. Conclusions The age of first sexual intercourse could be a variable that might qualify the selection among young women who are really at a higher risk for HSIL.
