The Italian Euromelanoma Day: evaluation of results and implications for future prevention campaigns.
2012
Background Melanoma incidence/mortality is increasing worldwide. “Euromelanoma Day” is a pan-European campaign for skin cancer prevention. Results of the 2010 Euromelanoma Day in Italy are reported herein. Materials and methods A questionnaire was used to collect data on participants' characteristics and suspected skin cancers. Result A total of 1085 participants was screened (64.1% females, median age 44 years). Suspicion rate, detection rate, and positive predictive values for melanoma were 1.3, 0.28 and 21.4%, respectively. Poorly educated, ≥35 years old, pale-skinned males were at higher risk for skin cancer than highly educated, <35 years old, darker-skinned females, although the latte…
Tumor-associated autoantibody signature for the early detection of gastric cancer
2012
Autoantibodies against tumor-associated antigens are very attractive biomarkers for the development of noninvasive serological tests for the early detection of cancer because of their specificity and stability in the sera. In our study, we applied T7 phage display-based serological analysis of recombinant cDNA expression libraries technique to identify a representative set of antigens eliciting humoral responses in patients with gastric cancer (GC), produced phage-antigen microarrays and exploited them for the survey of autoantibody repertoire in patients with GC and inflammatory diseases. We developed procedures for data normalization and cutoff determination to define sero-positive signal…
Reasons for participating in the Valencian Community Colorectal Cancer Screening Programme by gender, age, and social class
2014
Objective: To know the reasons to participate or not in a colorectal cancer (CCR) screening programme and to analyze the differences by sex, age and social class. Methods: Cross-sectional study by a telephone survey directed to a sample of men and women aged between 50-74 year old, participants (n = 383) and non participants (n = 383) in the CCR screening programme of Valencian Community. Descriptive analysis and logistic regression models estimating the Odds Ratio (p < 0.05). Results: The main reasons to participate are "it is important for health" (97.9 %) and "the test is easy" (97.6 %); and to non participate are "no CCR symptoms" (49.7 %) and "didn't receive invitation letter" (48.3 %)…
Investigation of Complement Activation Product C4d as a Diagnostic and Prognostic Biomarker for Lung Cancer
2013
[EN] Background There is a medical need for diagnostic biomarkers in lung cancer. We evaluated the diagnostic performance of complement activation fragments. Methods We assessed complement activation in four bronchial epithelial and seven lung cancer cell lines. C4d, a degradation product of complement activation, was determined in 90 primary lung tumors; bronchoalveolar lavage supernatants from patients with lung cancer (n = 50) and nonmalignant respiratory diseases (n = 22); and plasma samples from advanced (n = 50) and early lung cancer patients (n = 84) subjects with inflammatory lung diseases (n = 133), and asymptomatic individuals enrolled in a lung cancer computed tomography screenin…
Applications of OralCDx ® methodology in the diagnosis of oral leukoplakia
2011
Objective: We aim to evaluate the effectiveness of the brush biopsy technique using OralCDx ® (OralScan Laboratories Inc., Suffern, NY) as a new method for early diagnosis and control of a “potentially malignant disorder” such as oral leukoplakia. Design of the study: We performed a study in which samples were taken using OralCDx ® on 24 patients who visited the Master of Oral Medicine, Oral Surgery and Implantology of the University of Santiago de Compostela between February 2009 and May 2010. These patients presented clinical and histological lesions that were consistent with oral leukoplakia. We evaluated the relationship between the keratinization degree of the lesions and cell represen…
Long-term effect of faecal occult blood screening on incidence and mortality from colorectal cancer
2014
Abstract Background Several randomized trials have shown a reduction of colorectal cancer mortality by screening using guaiac-based faecal occult blood tests. However, little is known on the long-term effect of screening at the population level in everyday practice. Methods Small-sized geographic areas including a total of 91,199 individuals were allocated to either biennal screening using the Hemoccult-II test or no screening. The expected mortality and incidence in the cohort invited to screening was determined using mortality and incidence in the non-screened population. Results Colorectal cancer mortality was significantly lower in the population invited to screening than in the non-scr…
Delay in the Diagnosis of Breast and Colorectal Cancer in People With Severe Mental Disorders
2020
Background People with severe mental disorders have a worse cancer prognosis, with higher mortality rates than the general population, and this could be partially attributed to a later detection. Breast cancer and colorectal cancer have mass population screenings in Spain, but the influence in early diagnosis is unknown in persons with severe mental disorders. Objective To compare the severity of breast and colorectal cancers at diagnosis in people with and without mental disorders. Methods This was an observational, retrospective, case-control study with 1:2 matching performed in Eastern Spain. Data were retrieved for analysis from electronic medical records. Results The study included 111…
Does Family History of Cancer Influence Undergoing Screening and Gastrointestinal Investigations?
2020
Background and Aims: Although a family history of cancer (FHC) can modify the lifestyle and attitudes towards participation in cancer screening programs, studies on this relationship show mixed results and vary across populations. The objectives of the study were to compare sociodemographic characteristics, history of gastrointestinal (GI) investigations and Helicobacter pylori eradication, and modifiable cancer risk factors between those with FHC and those with no FHC (NFHC), and to investigate the association between FHC and a history of GI investigations.
 Methods: A total of 3,455 questionnaires from the pilot study of the “Helicobacter pylori eradication and pepsinogen testing for…

Estimation of lead-time bias and its impact on the outcome of surveillance for the early diagnosis of hepatocellular carcinoma.
2014
Lead-time is the time by which diagnosis is anticipated by screening/surveillance with respect to the symptomatic detection of a disease. Any screening program, including surveillance for hepatocellular carcinoma (HCC), is subject to lead-time bias. Data regarding lead-time for HCC are lacking. Aims of the present study were to calculate lead-time and to assess its impact on the benefit obtainable from the surveillance of cirrhotic patients. Background & Aims: Lead-time is the time by which diagnosis is anticipated by screening/surveillance with respect to the symptomatic detection of a disease. Any screening program, including surveillance for hepatocellular carcinoma (HCC), is subject to …
