Optimal withdrawal time in initial surveillance colonoscopy after colorectal cancer surgery: comparison between anterior/low anterior resection and right hemicolectomy.

Purpose: This study aimed to investigate the optimal withdrawal time (WT) for initial surveillance colonoscopy after curative resection for colorectal cancer (CRC) by comparing anterior/low anterior resection (AR/LAR) and right hemicolectomy (RHC) groups.

Methods: This retrospective study analyzed 1,212 patients who underwent initial surveillance colonoscopy after CRC resection between 2015 and 2022. The patients were divided into the AR/LAR (n = 846) and RHC (n = 366) groups.

Effective utilization of polypectomy in endoscopic salvage treatment of rectal neuroendocrine tumors: a retrospective cohort study.

Purpose: Current guidelines recommend endoscopic resection for rectal neuroendocrine tumors (RNETs) under 10 mm. Incomplete resections necessitate salvage procedures, highlighting the need for complete R0 resection. This study evaluates the efficacy and safety of wide hot snare polypectomy (WHSP) compared to endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) for the salvage treatment of small RNETs.

Cannabidiol Enhances Atezolizumab Efficacy by Upregulating PD-L1 Expression via the cGAS-STING Pathway in Triple-Negative Breast Cancer Cells.

The treatment of patients with triple-negative breast cancer (TNBC) relies on cytotoxic therapy. Currently, atezolizumab and chemotherapy can be combined in patients with TNBC. However, this approach is not effective for all patients, with many tumors showing low responsiveness to atezolizumab.

Daunorubicin induces GLI1‑dependent apoptosis in colorectal cancer cell lines.

Daunorubicin, also known as daunomycin, is a DNA‑targeting anticancer drug that is used as chemotherapy, mainly for patients with leukemia. It has also been shown to have anticancer effects in monotherapy or combination therapy in solid tumors, but at present it has not been adequately studied in colorectal cancer (CRC). In the present study, from a screening using an FDA‑approved drug library, it was found that daunorubicin suppresses GLI‑dependent luciferase reporter activity.

Patterns of δN in forest soils and tree foliage and rings between climate zones in relation to atmospheric nitrogen deposition: A review.

The stable nitrogen (N) isotope ratio (δN) of forest samples (soils, tree foliage, and tree rings) has been used as a powerful indicator to explore the responses of forest N cycling to atmospheric N deposition. This review investigated the patterns of δN in forest samples between climate zones in relation to N deposition. Forest samples exhibited distinctive δN patterns between climate zones due to differences in site conditions (i.

Impact of D3 lymph node dissection on upstaging and short-term survival in clinical stage I right-sided colon cancer.

Background: D3 lymph node dissection is becoming the standard procedure for the treatment of advanced right colon cancer and has shown increasing evidence of its oncologic benefit. However, a clear indication for its application is lacking and data on this topic is unsatisfactory. Thus, the necessity for D3 lymph node dissection in clinical stage I right colon cancer remains controversial.

Guidelines for accreditation of endoscopy units: quality measures from the Korean Society of Coloproctology.

Purpose: Colonoscopy is an effective method of screening for colorectal cancer (CRC), and it can prevent CRC by detection and removal of precancerous lesions. The most important considerations when performing colonoscopy screening are the safety and satisfaction of the patient and the diagnostic accuracy. Accordingly, the Korean Society of Coloproctology (KSCP) herein proposes an optimal level of standard performance to be used in endoscopy units and by individual colonoscopists for screening colonoscopy.

Patients completed questionnaires and underwent assessment of the outcome variables at the start of chemotherapy and upon completion of treatment.

Cannabidiol Overcomes Oxaliplatin Resistance by Enhancing NOS3- and SOD2-Induced Autophagy in Human Colorectal Cancer Cells.

Although oxaliplatin is an effective chemotherapeutic drug for colorectal cancer (CRC) treatment, patients often develop resistance to it. Therefore, a new strategy for CRC treatment is needed. The purpose of this study was to determine the effect of cannabidiol (CBD), one of the components of the cannabis plant, in overcoming oxaliplatin resistance in CRC cells.

Cannabidiol Enhances the Therapeutic Effects of TRAIL by Upregulating DR5 in Colorectal Cancer.

Cannabidiol, a major non-psychotomimetic compound derived from , is a potential therapeutic agent for a variety of diseases such as inflammatory diseases, chronic neurodegenerative diseases, and cancers. Here, we found that the combination of cannabidiol and TNF-related apoptosis-inducing ligand (TRAIL) produces synergistic antitumor effects in vitro. However, this synergistic effect was not observed in normal colonic cells.

Cannabidiol-induced apoptosis is mediated by activation of Noxa in human colorectal cancer cells.

Cannabidiol (CBD), one of the compounds present in the marijuana plant, has anti-tumor properties, but its mechanism is not well known. This study aimed to evaluate the apoptotic action of CBD in colorectal cancer (CRC) cells, and focused on its effects on the novel pro-apoptotic Noxa-reactive oxygen species (ROS) signaling pathway. CBD experiments were performed using the CRC cell lines HCT116 and DLD-1.
