Long-term survival in malignant disease is often linked to intensified therapeutic interventions. We report the case of a colonic cancer in a 78 years old female patient, who underwent her first operation in 1987 for a symptomatic T4 carcinoma. Since then, the patient has always denied any form of follow-up examination and adjuvant therapy. Recently, she has undergone her fourth operation, which for the first time demonstrated peritoneal carcinosis, and is still in very good health.Clinical experience shows that in some cases standard therapies may unexpectedly produce extremely long survival times. This has to be kept in mind when the value of prognostic markers is discussed and limits the validity of survival data in the context of small scale studies dealing with especially extended therapeutic protocols.

Colon cancer poses a significant threat to global health, and studies have shown a correlation between physical activity (PA) and the incidence of colon cancer. However, existing research has not quantitatively analyzed PA to evaluate its impact on the risk of colon cancer comprehensively. Data related to the study were obtained from the NHANES database for participants aged 20 and above between 2007 and 2018.

The purpose of this study was to evaluate EpiColon, a novel human organotypic 3D colon microtissue prototype, developed to assess colonic drug disposition, with a particular focus on permeability ranking, and compare its performance to Caco-2 monolayers. EpiColon was characterized for barrier function using transepithelial electrical resistance (TEER), morphology via histology and immunohistochemistry, and functionality through drug transport studies measuring apparent permeability (P). Cutoff thresholds for the permeability of FITC-dextran 4 kDa (FD4), FITC-dextran 10 kDa (FD10S), and [C]mannitol were established to monitor microtissue integrity.

Purpose: In this study, we investigated the progression of high-grade dysplasia (HGD)/CRC in patients with hereditary colorectal cancer syndromes (HCSS) and concomitant inflammatory bowel diseases (IBDs).
Methods: We described the natural history of a series of patients with confirmed diagnosis of hereditary colorectal cancer syndromes (HCCSs) and concomitant IBDs who were referred to the Hereditary Digestive Tumors Registry at the Fondazione IRCCS Istituto Nazionale dei Tumori of Milan.
Results: Between January 1989 and April 2024, among 450 patients with APC-associated polyposis and 1050 patients with Lynch syndrome (LS), we identified six patients with IBDs (five with UC, one with ileal penetrating CD) and concomitant HCCSs (five with LS, one with APC-associated polyposis).

The current work introduces the hybrid ensemble framework for the detection and segmentation of colorectal cancer. This framework will incorporate both supervised classification and unsupervised clustering methods to present more understandable and accurate diagnostic results. The method entails several steps with CNN models: ADa-22 and AD-22, transformer networks, and an SVM classifier, all inbuilt.

Purpose: Though prior studies have proven CTC's efficacy in outpatients, its utility in the inpatient setting has not been studied. We evaluated the efficacy of a modified CTC protocol in the inpatient setting, primarily for patients awaiting organ transplantation.
Methods: This retrospective study compared a group of inpatient CTCs from 2019 to 2021 and a randomly selected, age-matched 2:1 control group of outpatient CTCs.
