Background: It would be valuable to determine whether or not asymptomatic patients 60 to 65 years of age with normal colonoscopies should continue to undergo serial colorectal cancer surveillance examinations.
Methods: Data were obtained from retrospective review of our existing database. Additional data were obtained from patients' medical records, office charts, and pathology reports. In situ endoscopic measurements were performed using a biopsy forceps that was 7 mm when fully extended.
Results: Over the past 25 years, 699 asymptomatic patients between 60 and 65 years of age underwent colonoscopies which revealed no pathology. As part of their routine continuing colorectal surveillance and without any prior abnormal endoscopic findings, 56 of these patients underwent a total of 123 colonoscopies after age 65. Thirty-seven patients (66%) had surveillance colonoscopies that continued to be normal while 13 patients (23%) were diagnosed with colorectal adenomas and 6 patients (11%) were found to have hyperplastic polyps. No cancers were discovered.
Conclusions: Patients over the age of 65 should continue to undergo colorectal surveillance even if prior examinations have been negative.

Background: Colorectal cancer (CRC) remains one of the most common causes of cancer-related mortality worldwide. Its progression is influenced by complex interactions involving genetic, epigenetic, and environmental factors. Non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), have been identified as key regulators of gene expression, affecting diverse biological processes, notably programmed cell death (PCD).

Background: Germline heterozygous pathogenic variants (PVs) in TP53 cause Li-Fraumeni syndrome (LFS), a condition associated with increased risk of multiple tumor types. As the associated cancer risks were refined over time, clinical criteria also evolved to optimize diagnostic yield. The implementation of multi-gene panel germline testing in different clinical settings has led to the identification of TP53 PV carriers outside the classic LFS-associated cancer phenotypes, leading to a broader cancer phenotypic redefinition and to the renaming of the condition as "heritable TP53-related cancer syndrome" (hTP53rc).

Background: Whether the intake of whole grain foods can protect against lung cancer is a long-standing question of considerable public health import, but the epidemiologic evidence has been limited. Therefore we aim to investigate the relationship between whole grain food consumption and lung cancer in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) cohort.
Methods: Diet was assessed with a self-administered Diet History Questionnaire (DHQ) at baseline.
Clinical and economic effects of the transformation from an open to a laparoscopic center for colorectal surgery.

Purpose: The purpose of this study was to assess the feasibility of transitioning from open to laparoscopic surgery for colorectal carcinoma in a primary care hospital setting. Despite the recognized benefits of laparoscopic surgery in postoperative recovery and its demonstrated oncological equivalence, only a minority of patients (30-40%) in Germany undergo laparoscopic procedures, primarily due to concerns which, in addition to the perioperative quality data and economic aspects, focus on patient safety.
Methods: Over a three-year period (2012-2014), the transformation process was observed in a colorectal cancer center.

Background: Inadequate bowel perfusion is among risk factors for colorectal anastomotic leaks. Perfusion can be assessed with indocyanine green fluorescence angiography (ICG) during colon resections. Possible benefits from its systematic use in high-risk patients with rectal cancer remain inconsistent.
