The use COX-2 inhibitors induces regression of adenoma polyps and disrupts the sequence adenoma colorectal carcinoma. So that, this can be used in chemoprevention of colorectal cancer and also in cancer localised in other segments of the digestive tract. So far there is no agreement regarding the beginning of the treatment, the minimal efficient dose, the span of time required for chemoprevention. As the current studies in this field are quite encouraging we believe that in the next future COX-2 inhibitors could be used not only in chemoprevention but also in tumoral regression, and as a codrug in chemiotherapy of colorectal cancer.

Voxel-Based Dosimetry Predicts Local Tumor Progression Post 90Y Radiation Segmentectomy of Colorectal Liver Metastases.
Clin Nucl Med
November 2024
From the Interventional Oncology/Radiology Service, Department of Radiology, Memorial Sloan Kettering Cancer Center, New York, NY.
Background: Radiation segmentectomy (RS) is an alternative potential local curative treatment for selected colorectal liver metastases (CLMs) not amenable to ablation or limited resection.
Purpose: The aim of this study was to evaluate the dosimetric response of low volume CLMs to RS in heavily pretreated patients who are not candidates for resection or percutaneous ablation.
Patients And Methods: This single-center retrospective study evaluated CLMs patients treated with RS (prescribed tumor dose >190 Gy) from 2015 to 2023.
Introduction: Recently, a three-step endoscopic scale, known as the Diverticular Inflammation and Complication Assessment (DICA), was introduced to predict the course of diverticular disease (DD), yielding some promising outcomes. However, analyses were performed only for symptomatic individuals.
Objectives: The aim of our study was to prospectively evaluate the predictive value of DICA in asymptomatic individuals with no previous diagnosis of DD who underwent colorectal cancer screening colonoscopy.
Rise in Minimally Invasive Surgery for Colorectal Cancer Is Associated With Adoption of Robotic Surgery.

Department of Colon and Rectal Surgery, The University of Texas MD Anderson Cancer Center, Houston, Texas.
Background: Minimally invasive surgery is associated with improved short-term outcomes and similar long-term oncologic outcomes for colorectal cancer patients compared with open surgery. Although the robotic approach has ergonomic and technical benefits, how it has impacted utilization of traditional laparoscopic surgery and minimally invasive surgery overall is unclear.
Objective: Describe trends in open, robotic, and laparoscopic approaches for colorectal cancer resections and examine factors associated with minimally invasive surgery.

Upregulation of LncRNAs G2E3-AS1 and BACE1-AS as Prognostic Biomarkers in Metastatic Colorectal Cancer.

January 2025
Department of Biology, Faculty of Basic Sciences, Shahrekord Branch, Islamic Azad University, Shahrekord, Iran.
Background: Despite the current diagnostic techniques and therapeutic methods for colorectal cancer (CRC), patients are often diagnosed at advanced stages of colorectal cancer with poor prognosis and distant metastasis. Recently, numerous investigations have highlighted the crucial role of lncRNAs in cancer development, progression, invasion, and metastasis. This study investigated less well-characterized genes in the colorectal cancer metastasis process using bioinformatics analysis and their confirmation by experimental methods.
