Evaluation of the diagnostic value of a Modified Liquid-Based Cytology using OralCDx Brush in early detection of oral potentially malignant lesions a…
2009
Objectives: To determine diagnostic value of modified Liquid Based Brush Biopsy technique. Study design: 26 oral premalignant and malignant lesions in 25 patients (12 females; 54.23±19.77 years and 13 males; 53.77±15.43 years) underwent Modified (Liquid Based) Brush Biopsy and scalpel biopsy simultaneously from the same area. Results: There were 16 positive and 10 negative brush biopsy results, with no inadequate readings. Histological findings were compatible with oral leukoplakia(n=5)with dysplasia, Oral lichen planus and lichenoid reaction(n=7) (with or without dysplasia)oral squamous cell carcinoma(n=11),verrucous carcinoma(n=1) and granular cell tumors( n=2). Sensitivity, specificity, …
Screening for gastric cancer using exhaled breath samples.
2019
Abstract Background The aim was to derive a breath-based classifier for gastric cancer using a nanomaterial-based sensor array, and to validate it in a large screening population. Methods A new training algorithm for the diagnosis of gastric cancer was derived from previous breath samples from patients with gastric cancer and healthy controls in a clinical setting, and validated in a blinded manner in a screening population. Results The training algorithm was derived using breath samples from 99 patients with gastric cancer and 342 healthy controls, and validated in a population of 726 people. The calculated training set algorithm had 82 per cent sensitivity, 78 per cent specificity and 79 …
Clinical performance of the Nevisense system in cutaneous melanoma detection: an international, multicentre, prospective and blinded clinical trial o…
2014
Summary Background Even though progress has been made, the detection of melanoma still poses a challenge. In light of this situation, the Nevisense electrical impedance spectroscopy (EIS) system (SciBase AB, Stockholm, Sweden) was designed and shown to have the potential to be used as an adjunct diagnostic tool for melanoma detection. Objectives To assess the effectiveness and safety of the Nevisense system in the distinction of benign lesions of the skin from melanoma with electrical impedance spectroscopy. Methods This multicentre, prospective, and blinded clinical study was conducted at five American and 17 European investigational sites. All eligible skin lesions in the study were exami…
Total body skin examination for skin cancer screening in patients with focused complaints
2012
Background. The value of total body skin examination (TBSE) for skin cancer screening is controversial. Objective: We sought to determine whether TBSE could be helpful in patients with focused skin symptoms who would not otherwise have undergone TBSE. Methods: In a prospective, multicenter, cross-sectional study consecutive adult patients were recruited during a period of 18 months. Physicians first inspected, problem areas and uncovered areas and then performed TBSE. Equivocal lesions detected in both steps were excised or biopsied. Primary outcomes were the absolute and relative risks of missing skin cancer and the number of patients needed to examine to detect melanoma or another maligna…
Prevention and early detection of tuberculosis
1996
1,570 subjects with known TB contacts (active TB, old TB and primary infection) and individuals with no known contacts but belonging to 'defined TB risk groups' were screened at the Department of Tuberculosis Prevention at the La Fe Hospital in Valencia. The total infection rate was 40.13% and active TBC was diagnosed in 2.23% of the population screened. Infection and disease rates were significant in all the groups examined, showing the need for correct screening not only for active TB contacts but also for child primary infection contacts, old TB cases not previously screened and subjects with no known contacts but belonging to a 'TB risk group'.
Telomere length in leukocytes and cervical smears of women with high-risk human papillomavirus (HR HPV) infection
2019
Objective: Persistent high-risk HPV (HR HPV) infection leads to the development of squamous intraepithelial lesions, which in turn may progress to cervical cancer. Telomere elongation or shortening may indicate a carcinogenesis process. In the present study, we analyzed telomere length from blood and cervical smears of women without and with high-risk HPV infection. Materials and methods: Telomere length was quantified by real-time PCR in blood and cervical smears from 48 women with high-risk HPV infection and HGSIL or LGSIL, 29 women HR-HPV positive without SIL, and 11 HPV-negative women. Results: No correlation was found between age and telomere length in blood and cervical smears. Women …
Cervical Cancer Screening in Women With Severe Mental Disorders An Approach to the Spanish Context
2018
Background The incidence of invasive cervical cancer and its mortality have been reduced through primary and secondary prevention. Screening rates tend to be lower in vulnerable groups, such as people with severe mental disorders, who have a later detection of cancer and a higher mortality. The access of these women to cervical cancer screening is uncertain in our context. Objective The aim of this study was to determine the cervical cancer screening rates in women with severe mental disorders. Methods This was a descriptive cross-sectional study. Women 25 to 65 years old who were admitted during 2016 to the psychiatric unit of a public hospital in Spain were included in the study, and it w…
About invasive cervical cancer: a French population based study between 1998 and 2010
2015
Abstract Objectives The new French cancer plan provides the implementation of organized screening. To make an assessment of the situation, we aim to describe clinical, tumor and survival characteristics of patients with invasive cervical cancer. Study design Data on women suffering from invasive cervical cancer and diagnosed from 1998 to 2010 were provided by the Cote d’Or breast cancer registry. Survival was described using the Kaplan–Meier method and prognostic factors of survival were estimated in a Cox proportional hazard model. Results On the whole, 1019 cancers have been collected including 311 (30.5%) invasive ones. The peak incidence was between 40 and 49 years, with an average age …
Early detection of embryonic malformations by transvaginal and color Doppler sonography.
1994
A total of 834 women with uneventful pregnancies were followed prospectively until the 15th week of gestation by TVS to screen for early embryonic malformations. Twenty-eight embryonic anomalies were detected in this series (3.3%). The median gestational age at diagnosis was 11 (range, 8 to 15) weeks. Two neural tube defects were missed by early TVS screening. Two suspected abdominal wall defects were not confirmed by repeat mid-second trimester abdominal sonography representing 6.7% of all fetal malformations evident by 24 weeks of gestation. The sensitivity and specificity of TVS screening for fetal malformations in this series were 93.3 and 99.7%, respectively. In addition, the role of T…
Post-reproductive aged women: a lost generation in the cervical cancer screening programme
2020
The aims of the study were to find out why some post-reproductive aged women did not participate in the organised cervical cancer screening programme in Latvia and to clarify factors that would motivate them to take part. A cross-sectional study was carried out between January and July 2017 among female patients in three general practitioner (GP) practices. GP practice nurses used the Latvian national health service database to identify women aged 25–70 who had not participated in the organised programme for the last 3 years. Participants were asked to complete a specially developed questionnaire. The results were then compared between three age groups: 25–34, 35–49 and 50–70 years. Include…
