Cervical cancer prevention: Feasibility of self-sampling and HPV testing in rural and urban areas of Bolivia: An observational study.

Background: Cervical cancer is a major health problem in Latin America. In 2019, the Italian Agency for Development Cooperation (La Paz regional site) conducted a pilot study to estimate the prevalence of high-risk human papillomavirus (HPV) and the feasibility of HPV screening in Bolivia through self-sampling and portable and transportable laboratory instruments for HPV testing in urban and rural areas.

Methods: Women aged 20-65 years from La Paz (urban area), Toro Toro (rural area), and Acasio (rural area) were enrolled in local public health centers between Dec 1, 2019, and June 30, 2021.

Lung Cancer Screening with Low-Dose CT: What We Have Learned in Two Decades of ITALUNG and What Is Yet to Be Addressed.

The ITALUNG trial started in 2004 and compared lung cancer (LC) and other-causes mortality in 55-69 years-aged smokers and ex-smokers who were randomized to four annual chest low-dose CT (LDCT) or usual care. ITALUNG showed a lower LC and cardiovascular mortality in the screened subjects after 13 years of follow-up, especially in women, and produced many ancillary studies. They included recruitment results of a population-based mimicking approach, development of software for computer-aided diagnosis (CAD) and lung nodules volumetry, LDCT assessment of pulmonary emphysema and coronary artery calcifications (CAC) and their relevance to long-term mortality, results of a smoking-cessation intervention, assessment of the radiations dose associated with screening LDCT, and the results of biomarkers assays.

The 5-year risk of recurrence of grade 2/3 cervical intraepithelial neoplasia after treatment in a population screening programme by human papillomavirus status: A cohort study in central Italy.

Objectives: (a) To estimate the risk of recurrent cervical intraepithelial neoplasia, grade 2/3 or worse (CIN2+/CIN3+), lesions within 5 years of follow-up in human papillomavirus-negative/human papillomavirus-positive cohorts; (b) to assess whether certain risk factors can predict the recurrence of CIN2+/CIN3+ lesions; and (c) to provide recommendations for follow-up after treatment of cervical intraepithelial neoplasia, grade 2/3 to prevent cervical cancer

Setting: Organized cervical cancer screening programme in Central Italy.

Methods: We included 1063 consecutive first excisional treatments performed between 2006 and 2014 for screening-detected cervical intraepithelial neoplasia, grade 2/3 lesions among women aged 25-65. The study population was divided into two groups according to the human papillomavirus test results performed 6 months after treatment: Human papillomavirus-negative and human papillomavirus-positive cohorts.

The Consensus Project: Participation in cervical cancer screening by the first cohorts of girls offered HPV vaccination at age 15-16 years in Italy.

Objective: To evaluate the association between human papillomavirus vaccination status and participation in cervical cancer screening (at age 25) by the first cohorts of girls who were offered vaccination at the age of 15 to 16 years in Italy.

Methods: Women born in 1993, 1994 and 1995 were invited to participate in cervical cancer screening between 2018 and 2020. We report participation in screening by vaccination status in three large areas, Florence province, Piedmont region and Savona province, where the Consensus Project was carried out.

Assessment of the feasibility of pool testing for SARS-CoV-2 infection screening.

Background: SARS-CoV-2 pandemic represented a huge challenge for national health systems worldwide. Pooling nasopharyngeal (NP) swabs seems to be a promising strategy, saving time and resources, but it could reduce the sensitivity of the RT-PCR and exacerbate samples management in terms of automation and tracing. In this study, taking advantage of the routine implementation of a screening plan on health workers, we evaluated the feasibility of pool testing for SARS-CoV-2 infection diagnosis in the presence of low viral load samples.

Pool testing on random and natural clusters of individuals: Optimisation of SARS-CoV-2 surveillance in the presence of low viral load samples.

Facing the SARS-CoV-2 epidemic requires intensive testing on the population to early identify and isolate infected subjects. During the first emergency phase of the epidemic, RT-qPCR on nasopharyngeal (NP) swabs, which is the most reliable technique to detect ongoing infections, exhibited limitations due to availability of reagents and budget constraints. This stressed the need to develop screening procedures that require fewer resources and are suitable to be extended to larger portions of the population.

Cervical screening during the COVID-19 pandemic: optimising recovery strategies.

Disruptions to cancer screening services have been experienced in most settings as a consequence of the COVID-19 pandemic. Ideally, programmes would resolve backlogs by temporarily expanding capacity; however, in practice, this is often not possible. We aim to inform the deliberations of decision makers in high-income settings regarding their cervical cancer screening policy response.

Prognostic selection and long-term survival analysis to assess overdiagnosis risk in lung cancer screening randomized trials.

Objectives: Overdiagnosis in low-dose computed tomography randomized screening trials varies from 0 to 67%. The National Lung Screening Trial (extended follow-up) and ITALUNG (Italian Lung Cancer Screening Trial) have reported cumulative incidence estimates at long-term follow-up showing low or no overdiagnosis. The Danish Lung Cancer Screening Trial attributed the high overdiagnosis estimate to a likely selection for risk of the active arm.

Interlaboratory concordance of p16/Ki-67 dual-staining interpretation in HPV-positive women in a screening population.

Background: p16/Ki-67 dual staining is a candidate biomarker for triaging human papillomavirus (HPV)-positive women. Reproducibility is needed for adopting a test for screening. This study assessed interlaboratory reproducibility in HPV-positive women.

Decreased cardiovascular mortality in the ITALUNG lung cancer screening trial: Analysis of underlying factors.

Objectives: In the ITALUNG lung cancer screening trial after 9.3 years of follow-up we observed an unexpected significant decrease of cardiovascular (CV) mortality in subjects invited for low-dose CT (LDCT) screening as compared to controls undergoing usual care. Herein we extended the mortality follow-up and analyzed the potential factors underlying such a decrease.

Smoking Cessation in the ITALUNG Lung Cancer Screening: What Does "Teachable Moment" Mean?

Background: Changes in smoking habits and predictors of smoking cessation were examined in the randomized ITALUNG lung cancer screening trial.

Methods: In three centers, eligible smokers or ex-smokers (55-69 years, ≥20 pack-years in the last 10 years) were randomized to receive annual invitation for low-dose computed tomography for 4 years or usual care. At invitation, subjects received written information for a free smoking cessation program.

Cost analysis of colorectal cancer screening with CT colonography in Italy.

Objective: Unit costs of screening CT colonography (CTC) can be useful for cost-effectiveness analyses and for health care decision-making. We evaluated the unit costs of CTC as a primary screening test for colorectal cancer in the setting of a randomized trial in Italy.

Methods: Data were collected within the randomized SAVE trial.

Multimodal lung cancer screening using the ITALUNG biomarker panel and low dose computed tomography. Results of the ITALUNG biomarker study.

Asymptomatic high-risk subjects, randomized in the intervention arm of the ITALUNG trial (1,406 screened for lung cancer), were enrolled for the ITALUNG biomarker study (n = 1,356), in which samples of blood and sputum were analyzed for plasma DNA quantification (cut off 5 ng/ml), loss of heterozygosity and microsatellite instability. The ITALUNG biomarker panel (IBP) was considered positive if at least one of the two biomarkers included in the panel was positive. Subjects with and without lung cancer diagnosis at the end of the screening cycle with LDCT (n = 517) were evaluated.

Mortality, survival and incidence rates in the ITALUNG randomised lung cancer screening trial.

Background: ITALUNG is contributing to the European evaluation of low-dose CT (LDCT) screening for lung cancer (LC).

Methods: Eligible subjects aged 55-69 years, smokers or ex-smokers (at least 20 pack-years in the last 10 years), were randomised to receive an annual invitation for LDCT screening for 4 years (active group) or to usual care (control group). All participants were followed up for vital status and cause of death (at the end of 2014) and LC incidence (at the end of 2013).

Interobserver reproducibility of cytologic p16 /Ki-67 dual immunostaining in human papillomavirus-positive women.

Background: The accumulation of cyclin-dependent kinase inhibitor 2A (p16 ) protein in a cell is associated with neoplastic progression in precancerous cervical lesions. Dual staining for p16 and Ki-67 has been proposed as a triage test in cervical cancer screening for women who test positive for human papillomavirus DNA. In this study, interobserver reproducibility of the interpretation of this test was assessed.

[Molecular biomarkers and early diagnosis of lung cancer: state of knowledge and future perspectives].

Lung cancer is the leading cause of cancer death worldwide and it would be essential to have effective tools to diagnose the disease in its early stages, to identify individuals at highest risk of developing the disease, and to set personalised therapies. The effectiveness of screening for lung cancer with low-dose CT (LDCT) in heavy smokers was demonstrated, in terms of reduction of cause-specific mortality, in recently published data by the study National Lung ScreeningTrial (NLST). In Europe, the introduction of LDCT as screening in individuals at risk is the object of a debate until the results of European randomized trials, expected in 2015-2016, are published.

HPV testing for primary cervical screening: Laboratory issues and evolving requirements for robust quality assurance.

This review aims to highlight the importance of Quality Assurance for Laboratories performing HPV test for Cervical Cancer Screening. An HPV test, to be used as primary screening test, must be validated according to international criteria, based on comparison of its clinical accuracy to HC2 or GP5+/6+ PCR-EIA tests. The number of validated platforms is increasing and appropriate Quality Assurance Programs (QAPs) which can interrogate longitudinal robustness and quality are paramount.

hr-HPV testing in the management of women with ASC-US+ and in the follow-up of women with cytological abnormalities and negative colposcopy. Recommendations of the Italian group for cervical cancer screening (GISCi).

Compared to spontaneous screening, an organized screening programme is characterized by the presence of protocols and recommendations for all stages including follow-up. Despite the availability of well-functioning screening programmes throughout the country, the follow-up protocol after an abnormal Pap test and negative colposcopy is not clearly defined in Italy, and there is no uniformity of indications. HPV testing for oncogenic human papillomavirus (hr-HPV) has a high negative predictive value (NPV) and high positive predictive value (PPV) for CIN2+ and its employment can reduce follow-up assessments.

The diffusion of screening programmes in Italy, years 2011-2012.

In this report, we present the results of cancer screening programmes in Italy for the years 2011-2012. This report is produced by the National centre for screening monitoring (ONS), together with the Italian professional multidisciplinary screening groups: GISMa (Italian group for mammographic screening), GISCor (Italian group for colorectal screening), and GISCi (Italian group for cervical screening). Since 2004, ONS has been monitoring and supporting Italian screening programmes, in accordance with a decree issued by the Ministry of Health.

Clinical impact of the analytical specificity of the hybrid capture 2 test: data from the New Technologies for Cervical Cancer (NTCC) study.

The Hybrid Capture 2 (HC2) test targets 13 human papillomavirus (HPV) types. Here, cross-reactivity with non-HC2-targeted HPV types is described. We aimed to define the proportion of HC2-positive women who had negative results with HC2-targeted HPV types and estimate its determinants and impact on women's health management.
