ABSTRACT
Introducción: a pesar de que la técnica de papanicolaou es el método más eficaz para la prevención y detección del cáncer cervicouterino, la precisión de esta herramienta sigue siendo controversial; debido a esto, existen esfuerzos médicos y científicos para mejorar la calidad del procedimiento. Objetivo: comparar la calidad en la toma de muestra entre la técnica convencional y la modificada. Material y métodos: estudio observacional descriptivo y comparativo en 150 muestras de citología cervical (75 muestras técnica convencional y 75 en técnica modificada) en mujeres de 25 a 64 años. Se analizaron variables emográficas, características del cérvix y calidad de la muestra. Se realizó estadística descriptiva y medidas de asociación. Estudio con riesgo mayor que el mínimo. Todas las participantes firmaron consentimiento informado. Resultados: la calidad de la muestra fue satisfactoria en el 92% para la técnica convencional frente al 89.3% para la técnica modificada. La causa principal de muestras insatisfactorias fue la celularidad insuficiente, la cual se presentó en el 6.7% de las muestras con técnica convencional frente al 12% de la técnica modificada, sin diferencia significativa entre ambas técnicas p = 0.575 (1.37; 0.45-4.1), hallazgos que rechazan la hipótesis de trabajo. Conclusiones: no hubo diferencia significativa al utilizar ambas pruebas, las muestras con calidad satisfactoria fueron similares entre ambas técnicas.
Background: Despite the fact that the Papanicolaou technique is the most effective method of prevention and detection of cervical cancer, the precision of this tool remains controversial; Because of this, there are medical and scientific efforts to improve the quality of the procedure. Objective: Compare the quality of sampling between the conventional and modified technique. Material and methods: Descriptive and comparative observational study in 150 cervical cytology samples (75 conventional technique samples and 75 in modified technique) in women aged 25 to 64 years. Demographic variables, characteristics of the cervix and quality of the sample were analyzed. Descriptive statistics and association measures were performed. Study with risk greater than the minimum. All participants signed an informed consent. Results: The quality of the sample was satisfactory in 92.0% for the conventional technique vs 89.3% for the modified technique. The main cause of unsatisfactory samples was insufficient cellularity 6.7% in conventional technique vs 12% of the modified technique, with no significant difference between both techniques p = 0.575 (1.37; 0.45-4.1), findings that reject the working hypothesis. Conclusions: There was no significant difference when using both tests, the samples with satisfactory quality were similar between both techniques.

Objective:To explore the clinical significance of colposcopy in cervical atypical squamous cell of undetermined significance(ASCUS).Methods: Total of 516 women in our department were diagnosed with ASCUS by cytological test(TCT), they were further colposcope test. 209 cases of cervical intraepithelial neoplassia(CIN)were biopsied under the colposcope. In 307 cases of chronic cervicitis were given conservative therapy for 1-3 treatment cycles. Twelve cases of second TCT examination abnormal were biopsied under the colposcope. 295 cases of those with negative cytology checks take TCT regularly.Results: Of the 516 cases, 221 cases of cervical were biopsy (42.82%). Among them, 30 cases were chronic cervicitis , 185 cases were cervical intraepithelial neoplasia (CIN I-III), 6 case were squamous cell carcinoma, respectively. 295 cases without cervical biopsy, the follow-up of 6-18 months TCT found no abnormality.Conclusion: For the patients with cervical ASCUS, colposcopy associate with pathology biopsy may be helpful for the diagnosis and can provide a reasonable and effective treatment scheme for patients.

Objective To study the clinical treatment methods for properties of unknown in elderly patients with atypical squamous cell of undertermind significant and above cervical lesions.Methods According to the clinical grouping of ASCUS in elderly patients with cervical lesions of different treatment methods,observation group 1 (348 cases) underwent colposcopy;observation group 2(316 cases) for high-risk human papillomavirus(HPV) detection,HPV positive colposcopy ;observation group 3 (129 cases) of cervical cytology examination regularly,squamous intraepithelial lesion colposcopy,compared three groups of clinical treatment.Results Liquid based cytology and three groups of 574 patients (TCT) and colposcopy and cervical biopsy,the results of intraepithelial neoplasia(C IN) above cervical lesions in 223 cases(38.9%),in which CIN Ⅰ 136 cases(23.7%),CIN Ⅱ in 64 cases(11.2%),CIN Ⅲ 20 cases(3.5%),3 cases of carcinoma in situ(0.5%) ;the group1 were observed in 348 cases,348 cases underwent colposcopy biopsy(100%),CIN Ⅱ above 36 cases(10.3%) were observed in the group 2;213 cases of colposcopy biopsy(67.4%),CIN Ⅱ above 38 cases (12%) were observed in the group 3 ; colposcopy examination in 13 cases (10.1%),3 cases of biopsy CIN Ⅱ of the cases(2.3%).Biopsy of CIN Ⅱ above the detection rate,the observation group 1,observation of the 2 groups had no significant differences(P ＞ 0.05),and observe the difference between the 3 groups was statistically significant(x2 =7.014,9.156,all P ＜ 0.05).Conclusion High-risk HPV detection of shunt ASCUS can reduce cervical lesions treatment process misdiagnosis,missed diagnosis and treatment of the problem of excessive.
ABSTRACT
BACKGROUND: We have retrospectively assessed the incidence and outcome of women diagnosed during a hospital-based cytology screening program with "atypical squamous cells (ASC)" and followed-up with loop electrical excision procedure (LEEP). METHODS: We analyzed 173,947 cases of cervical smears' follow-up cytology and histology findings. Previous or archival cytology with LEEP results were retrieved for 390 women with ASC of undetermined significance (ASC-US) and 112 with ASC, cannot exclude high-grade squamous intraepithelial lesion (ASC-H). RESULTS: On the follow-up cytology, of the 390 women initially diagnosed with ASC-US, 130 (33.3%) had no follow-up records of smears before LEEP; smears of 18 (4.6%) were negative for cytologic abnormalities, 193 (49.5%) were ASC-US, 24 (6.2%) were ASC-H, 111 (28.5%) were low grade squamous intraepithelial lesion (SIL), and 44 (11.4%) were high grade SIL. LEEP findings in these 390 women showed that 183 (46.9%) were negative, 73 (18.7%) were graded as cervical intraepithelial neoplasia (CIN) 1, 25 (6.4%) as CIN 2, 102 (26.2%) as CIN 3, and 7 (1.8%) had carcinoma. LEEP was performed in 112 women initially diagnosed with ASC-H; 36 (32.1%) were negative, 4 (3.6%) were graded as CIN 1, 7 (6.3%) as CIN 2, 60 (53.6%) as CIN 3, and 5 (4.5%) with carcinoma. CONCLUSIONS: Patients with ASC-H smears were at increased risk of SIL or carcnoma compared with patients with ASC-US. Careful follow-up is required in ASC patients.

Objective To discuss the significance of high-risk human papilloma virus ( HR-HPV) detection by hybrid capture 2 (Hc-2) in managing the women with atypical squamous cell of undetermined significance (ASCIIS) and low grade squamous intraepithelial lesion (LSIL) of thin prep liquid-based cytology (TCT). Methods One hundred and seventy-eight women with ASCUS and 108 women with LSIL were studied. The infection of HR-HPV in the women was analyzed. And sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were used to evaluate the significance of HR-HPV detection by Hc-2 in managing the women with ASCUS and LSIL of TCT. Results Sensitivity,specificity, PPV and NPV of HR-HPV DNA detection by Hc-2 in screening CIN II or above in ASCUS were 89.83% (53/59),53.78% (64/119), 49.07% (53/108), 91.43% (64/70) respectively,and in LSIL were 97.62%(41/42),22.73%(15/66), 44.57%(41/92), 93.75%( 15/16) respectively. Conclusion HR-HPV detection by Hc-2 is an effective measure in managing the women with ASCUS and LSIL of TCT.
ABSTRACT
OBJECTIVE: To evaluate qualification and determine the usefulness of human papillomavirus(HPV) DNA testing in women with cytologic smears read as atypical squamous cell of undetermined significance (ASCUS). METHOD: The study was based on 88 women with cytologic smears reported of ASCUS favoring either a reactive process or squamous intraepithelial lesion (SIL) from July 1999 to June 2000. Cytologic examination by Papanicolaou smear was based on the Bethesda System and cervical biopsy was done via coloscopy. the presence of high risk HPV DNA was determined with Hybrid capture assay. RESULTS: The overall incidence of cervical intraepithelial lesion (CIN) was higher in the group with ASCUS favoring SIL than in the group with ASCUS favoring reactive process(42.2 % vs 18.6 %; p<0.05). Women with ASCUS favoring SIL were 9.1 times more likely to have high grade SIL(CIN II/III) develop than were women group with ASCUS favoring reactive process(95% confidence interval, 1.08-76.0). High-risk HPV DNA was demonstrated in 39.8%(35 cases) and was associated a 8.8 times increased likelihood of histologic conformation of CIN(95% confidence interval, 3.09-24.7). The sensitivity of HPV assay for any CIN was 74% and specificity was 75%, whereas the corresponding values for the repeat Pap smear was 67% and 33%, respectively. CONCLUSION: Women with ASCUS favoring SIL was associated with a relatively high risk that the women was harboring SIL. The addiction of a high-risk HPV DNA assay to cytologic examination appears to provide for early detection of high grade CIN in women with ASCUS.
