The Landscape of Helicobacter pylori-related Gastric Carcinogenesis.

The relationship between Helicobacter pylori (H. pylori) and humans remains a complex enigma. While other factors contribute to gastric cancer (GC), their impact pales in comparison to the central role of H.

The Unappreciated Value of a Cheap, 'Good Enough' Method of Detecting Thyroid Cancer.

The advent of advanced molecular diagnostic techniques has revealed plenty of information about signaling pathways and gene regulation in cancer, as well as new inputs for the classification of cancer subtypes, diagnosis, prognosis, and prediction of response to therapy. However, in most cases we do not have single biomarkers yet and, therefore, the final diagnosis is often rendered by the combination of multiple results by means of complex algorithms, eventually leading to an increase in their costs. The problem of the costs of such tests is particularly relevant in the case of thyroid cancer (TC), because of the observed increase in the number of patients affected by thyroid nodules (TN)s, in what is considered a global pandemic.

Microbiota in gastrointestinal malignancies.

This manuscript provides an overview of the microbiota profile associated with precancerous lesions in the esophagus, stomach, and large bowel. The critical review of the available data reveals significant variability in the methods used for microbiota profiling. This variability may affect the reliable identification of specific biological links between histologically profiled neoplastic diseases and the microbiota population.

"Artificial histology" in colonic Neoplasia: A critical approach.

Background: The histological assessment of colorectal precancer and cancer lesions is challenging and primarily impacts the clinical strategies of secondary colon cancer prevention. Artificial intelligence (AI) models may potentially assist in the histological diagnosis of this spectrum of phenotypical changes.

Objectives: To provide a current overview of the evidence on AI-based methods for histologically assessing colonic precancer and cancer lesions.

Retrospective Analysis of the Effect of Postmenopausal Women Medications on SARS-CoV-2 Infection Progression.

Since the beginning of the COVID-19 pandemic, it has been evident that women and young people were less susceptible to severe infections compared to males. In a previous study, we observed a reduced prevalence of SARS-CoV-2 infections in hormonal-driven breast cancer patients undergoing SERM (selective estrogen receptor modulator) therapy with respect to other treatments inhibiting estrogen synthesis. In addition to being used in anticancer therapy, SERMs are also prescribed for postmenopausal osteoporosis prevention and treatment.

Host-related low-prevalence gastritides: Epidemiological and clinical characterization.

Introduction: A recent consensus meeting (RE.GA.IN) addressed "host-related, low-prevalence gastritis": eosinophilic (EoG), lymphocytic (Hp-pos_LyG and Hp-neg_LyG), collagenous (CollG), and granulomatous gastritis (GrG).

Could the mitotic count improve personalized prognosis in melanoma patients?

A number of studies have indicated that the mitotic rate may be a predictive factor for poor prognosis in melanoma patients. The aim of this study was to investigate whether the mitotic rate is associated with other prognostic clinical and anatomopathological characteristics. After adjusting for other anatomopathological characteristics, we then verified the prognostic value of the number of mitoses, determining in which population subgroup this variable may have greater prognostic significance on 3-year mortality.

Cutaneous melanoma in older patients.

Background: In industrialized countries, the aging population is steadily rising. The incidence of cutaneous malignant melanoma (CMM) is highest in old people. This study focuses on the clinicopathological profile of CMM and indicators of diagnostic-therapeutic performance in older patients.

Geographical and temporal differences in gastric and oesophageal cancer registration by subsite and morphology in Europe.

Background: Gastric and oesophageal cancers pose a serious public health concern. In 2020 a total of 189,031 incident cases (136,038 stomach, 52,993 oesophagus) and 142,508 deaths (96,997 stomach, 45,511 oesophagus) were estimated in Europe. Oesophago-gastric cancers are a heterogeneous disease, with different aetiology and epidemiology for the various topographic subsites and main histopathological types.

RE.GA.IN.: the Real-world Gastritis Initiative-updating the updates.

At the end of the last century, a far-sighted 'working party' held in Sydney, Australia addressed the clinicopathological issues related to gastric inflammatory diseases. A few years later, an international conference held in Houston, Texas, USA critically updated the seminal Sydney classification. In line with these initiatives, Kyoto Global Consensus Report, flanked by the Maastricht-Florence conferences, added new clinical evidence to the gastritis clinicopathological puzzle.

Thirty-two-year trends of cancer incidence by sex and cancer site in the Veneto Region from 1987 to 2019.

Background: This observational study considers the sex-specific incidence of the most incident cancers as recorded in the population-based Veneto Regional Cancer Registry over a period of more than 30 years (1987-2019).

Methods: The Veneto Regional Cancer Registry collected data for the time interval 1987-2019. Significant changes in incidence trends calculated on age-standardized incidence rates (Annual Percent Change-APC) were identified by join point regression analysis.

The descriptive epidemiology of melanoma in Italy has changed - for the better.

A recent research project using data from a total of 40 cancer registries has provided new epidemiologic insights into the results of efforts for melanoma control in Italy between the 1990s and the last decade. In this article, the authors present a summary and a commentary of their findings. Incidence increased significantly throughout the study period in both sexes.

Sex Differences in Soft Tissue Sarcoma: Incidence, Clinicopathological Profile, Survival, and Costs.

There are evident sex differences in the incidence of and mortality rates for several tumors. Soft tissue sarcomas (STSs) account for no more than 1% of all malignancies in adults. This study aimed to provide a comprehensive overview of the sex differences in the epidemiology of STSs and the related costs.

Indicators of clinical performance in monitoring soft tissue sarcoma management: a population-based perspective.

Background: Soft tissue sarcomas (STS) are rare malignancies which prognosis varies significantly by primary site, histological subtype, and tumor stage. Their low incidence, and the complexity of their clinico-pathological characteristics demand standardized, cancer-tailored diagnostics and therapies managed at high-volume, multidisciplinary care centers. This study evaluates the quality of STS management in north-east Italy (Veneto Region) through a list of defined clinical indicators.

Synchronous and metachronous multiple primary cancers in melanoma survivors: a gender perspective.

Background: Long-term survivors of cutaneous malignant melanoma (CMM) risk subsequent malignancies due to both host-related and environmental risk factors. This retrospective population-based study differentially assesses the risk of synchronous and metachronous cancers in a cohort of CMM survivors stratified by sex.

Methods: The cohort study (1999-2018) included 9,726 CMM survivors (M = 4,873, F = 4,853) recorded by the cancer registry of all 5,000,000 residents in the Italian Veneto Region.

PPIs and gastric cancer: any causal relationship?

Hydrochloric acid is crucial in gastric physiology. In 1978 cimetidine, the first H2 antagonist of histamine receptors on the gastric parietal cell was introduced into therapy, inducing acid. Lasting the years, several studies focused on the potential relationship between inducing hypo-achlorhydria and risk of developing gastric cancer.
