Colorectal cancer (CRC) diagnosed before the age of 50, known as early-onset CRC (eoCRC), is considered uncommon. We aimed at analysing the incidence of preneoplastic and neoplastic lesions of the colon and rectum in patients under 50 years old and to identify possible predictors Methods: We retrospectively collected data from 1778 patients under 50 years old (mean age 39.9±7.8) referred for colonoscopy between 2015-2018. Cumulative incidence of adenomas and eoCRC was assessed. Multivariable regression models were fitted Results: The cumulative incidence for adenomas was 11.0% (95% CI 9-12), while it was 1.5% (95% CI 1-2) for eoCRC (metastatic disease in 13/27 patients). Age as a continuous variable was associated with the presence of adenomas (incidence rate ratio 1.06; 95% CI 1.03-1.09; p<0.001). EoCRC arose in most cases in the rectum (13/27, 48.1%). Age ≥40 was the main risk factor (OR 2.25; 95% CI 1.35-3.73; p=0.002) for both adenomas (160/196 patients, 81.6%) and eoCRC (20/27 patients, 74.1%), while smoking seemed to have no role (p=0.772). The presence of alarm symptoms was statistically significant at bivariable analysis for eoCRC only (OR 3.70; 95% CI 1.49-9.22; p=0.005), as well as having multiple gastrointestinal symptoms (OR 19.85; 95% CI 2.64-149.42; p=0.004). Only 3/27 (11.1%) patients with eoCRC had a family history for CRC Conclusions: A high cumulative incidence rate of both adenomas and eoCRC was found, this latter occurring more common in patients aged 40-49, without apparent risk factors. The presence of alarm symptoms or multiple gastrointestinal symptoms led to a late diagnosis.

Most gastric neoplastic lesions appear in patients with gastric premalignant conditions. Here, we present the case of a 75-year-old woman with no prior history of infection, with a big gastric adenoma resected by endoscopic submucosal dissection. Histopathological examination revealed high-grade foveolar dysplasia.

Autoimmune gastritis (AIG) is a chronic inflammatory condition characterized by immune-mediated destruction of gastric parietal cells, leading to oxyntic atrophy, achlorhydria, and hypergastrinemia. While AIG was historically linked to gastric adenocarcinoma and type I neuroendocrine tumors (NETs), recent evidence suggests the risk of adenocarcinoma in AIG is lower than previously believed, particularly in Helicobacter pylori (H. pylori)-negative patients.

Papillomaviruses (PVs) frequently infect humans as well as non-human species. While most PV infections are asymptomatic, PVs can also cause hyperplastic papillomas (warts) as well as pre-neoplastic and neoplastic lesions. In this review, the life cycle of PVs is discussed, along with the mechanisms by which PVs cause hyperplastic and neoplastic diseases.

Dysbiosis of the gastrointestinal tract is the most common cause of disease in childhood and adulthood. The formation of the intestinal microbiome begins in utero, and composition modification during life depends mainly on various genetic, nutritional, and environmental factors. The main cause of intestinal dysbiosis is improper nutrition due to a short period of breastfeeding, insufficient intake of fresh fruits and vegetables, and/or consumption of a large amount of processed food.

Objective: We aimed to investigate the epidemiology of human papilloma virus (HPV)-related preneoplastic and neoplastic vulvar lesions in a large cohort of women living with HIV (WLWH).
Materials And Methods: We retrospectively selected 1,796 WLWH who had a gynecological examination, cervical cytology, high-risk (HR-) HPV test, vulvoscopy, and colposcopy with targeted biopsies when necessary between 1987 and 2020 at 2 Italian institutions. Univariable and multivariable regression analyses were carried out to test the association of the anamnestic and clinical data with the development of precancerous and cancerous lesions.
