Hallazgos no neoplásicos y anormalidades celulares epiteliales en citología cervical / Non Neoplastic Findings and Epithelial Cell Abnormalities in Cervical Cytology

Introducción: el examen citológico de Papanicolaou tiene como objetivo el diagnóstico de lesiones precancerosas o cancerosas del cuello uterino, una evaluación hormonal y de flora bacteriana. Objetivos: determinar la proporción de hallazgos no neoplásicos y las anormalidades epiteliales escamosas y glandulares remitidos al área de Citología del Hospital Nacional Docente Madre Niño San Bartolomé. Métodos: se diseñó una investigación de tipo analítico-correlacional prospectiva de corte transversal en todos los frotices referidos de cinco redes y microredes de salud. El procesamiento citológico se realizó en conformidad con los requerimientos internacionales para citología. La interpretación citológica se realizó según el Sistema Bethesda. Resultados: de 72 644 extendidos cérvicouterinos evaluados mediante sistema de calidad del Sistema Bethesda, la proporción de resultados con alteraciones cérvico-uterinas (prevalencia 6,5 por ciento; IC: 95 por ciento: 6,32 por ciento, 6,68 por ciento), negativos posevaluación y Hallazgos no neoplásicos fue de 4724 (6,5 por ciento), 35 318 (51,7 por ciento) y 32 602 (48,2 por ciento) muestras, respectivamente (p< 0,005). La probabilidad posprueba fue de 89,3 por ciento (IC: 95 por ciento: 87,1 por ciento a 91,1 por ciento; likelihood ratio LR > 10) y se estableció una correlación directa significativa entre los hallazgos/NLIM y las edades de los pacientes (rho= 0,477; p< 0,005). Además, 46,53 por ciento de estos hallazgos corresponden a flora sugestiva de vaginosis bacteriana, 22,5 por ciento a cambios reactivos asociados a inflamación y 21 por ciento a metaplasia escamosa. La asociación más frecuente fue la metaplasia escamosa, vaginosis bacteriana e inflamación severa 5,5 por ciento (1495 resultados). Conclusiones: la proporción de hallazgos no neoplásicos fue considerable y las anormalidades epiteliales escamosas y glandulares estuvieron sobre el promedio estándar(AU)

Introduction: The Pap test aims at diagnosing precancerous or cancerous lesions of the cervix, hormonal evaluation, and bacterial flora. Objectives: Determine the proportion of non-neoplastic findings, squamous and glandular epithelial abnormalities referred to the district ofHospital Nacional Docente Madre Niño San Bartolome. Methods: A prospective, analytical, correlational, cross-sectional research was designedfor all vaginal smear which were referred from five health networks and micro-networks. Cytological processing was carried out in accordance with applicable international requirements. Cytologic interpretation was performed according to Bethesda System. Results: Out of 72,644 cervical smears evaluated by Bethesda quality system, the proportion of results with cervical uterine disorders (prevalence 6.5 percent CI 95 percent: 6.32 percent, 6.68 percent) were 4724 (6.5 percent) samples, negative posevaluación was 35318 (51.7 percent) samples, and nonneoplastic findings 32 602 (48.2 percent) samples, (p< 0.005). Posttest probability was 89.3 percent (CI 95 percent: 87.1 percent to 91.1 percent; likelihood ratio LR > 10) and a significant direct correlation was established between the findings/nLiM and ages of patients (rho= 0.477; p< 0.005). Moreover, 46.53 percent of NIM flora suggestive corresponds to bacterial vaginosis (BV), 22.5 percent to reactive changes associated with inflammation and squamous metaplasia 21 percent (MET). The most frequent association was MET, VB, and severe inflammation 5.5 percent (1495 results). Conclusions: The proportion of non-neoplastic findings was considerable; squamous and glandular epithelial abnormalities were above average standard(AU)

Dosimetric study of three-dimensional image-quided brachytherapy combined with intracavitary/ interstitial brachytherapy in locally advanced cervical cancer / 中华放射肿瘤学杂志

Objective To explore the dosimetric advantages of computed tomography-based and ultrasound-guided three-dimensional image-quided brachytherapy (3D-IGBT) combined with intracavitary/interstitial (IC/IS) brachytherapy for locally advanced cervical cancer.Methods A total of 45 patients with FIGO (2009) stage ⅠB2-ⅣA locally advanced cervical cancer who received radical external beam radiotherapy and 3D-IGBT combined with IC/IS brachytherapy in our hospital from 2013 to 2014 were analyzed.After the treatment with 192Ir-based IC/IS brachytherapy,patients had needles removed from the original images and received treatment only from IC radiation sources.Dosimetric differences in the planning D90 for high-risk clinical target volume (HR-CTV),D90 for intermediate-risk CTV (IR-CTV),and D2 cm3 for the bladder,rectum,sigmoid colon,and small intestines were determined and analyzed by paired t-test.Results A total of 260 after-loading treatment plans,including IC/IS treatment plans for 130 patients and IC treatment plans for 130 patients,were made.The D90 for HR-CTV and D90 for IR-CTV in the IC/IS brachytherapy group were significantly higher than those in the IC brachytherapy group (P =0.000;P =0.000).Moreover,the average D2cm3 values for the bladder and rectum were significantly reduced in the IC/IS brachytherapy group compared with those in the IC brachytherapy group (P =0.000;P =0.006).Conclusions The 3D-IGBT combined with IC/IS brachytherapy not only achieves a higher dose for the target volume,but also reduces the radiation dose to the bladder and rectum in the treatment of locally advanced cervical cancer.

Clinical effect of thin-prep cell test and high-risk human papillomavirus in the diagnosis of cervical intraepithelial neoplasma and cervical carcinoma / 中国医师进修杂志

ObjectiveTo study the clinical application value of screening cervical precancerous lesions of high risk human papillomavirus(HPV) testing combined with thin-prep cell test(TCT) in prevention of cervical intraepithelial neoplasma (CIN) and cervical carcinoma. MethodsSeven hundred and sixty-three women were screened by high risk HPV test, TCT and pathology test of biopsy more. The positive coincident rate with the pathology test positive rate during the three technologies was compared.ResultsHigh risk HPV positive was 287 cases, the rate of infection was 37.61％(287/763), and pathology test positive was 82 cases, the coincident rate of which was 28.57％ ( 82/287 ) ; TCT positive was 78 cases, the rate of infection was 10.22％ (78/763), and pathology test positive was 50 cases, the coincident rate of which was 64.10％ (50/78) ; TCT + high risk HPV positive was 59 cases, pathology test positive was 47 cases, and the coincident rate of which was 79.66％ (47/59). Among each coincident rate,the differences were statistically significant (P＜ 0.05). The positive rate of high risk HPV infection CIN I was 32.26％( 10/31 ),CIN Ⅱ 41.38％ (12/29), CIN Ⅲ 93.55％ (29/31), squamous carcinoma of the cervix 96.88％ (31/32),respectively. ConclusionsThe positive rate of high risk HPV increases significantly with the grade of cervical precancerous lesions. It is of great significance to screen in the population for HPV and TCT in a regular time span,since it could not only decrease HPV infection rate and the incidence of cervical lesions,but also prevent the cervical cancer.
