Primary tumor resection self-expandable metallic stent in unresectable obstructive stage IV colorectal cancer: a comparative outcome study.

Purpose: The selection of primary tumor resection (PTR) self-expanding metallic stents (SEMS) in obstructive unresectable stage IV colorectal cancer (CRC) is critical, profoundly impacting patient outcome. This study evaluates the influence of PTR and SEMS on overall survival (OS) in conjunction with chemotherapy.

Methods: The analysis included 137 patients with obstructive, unresectable stage IV CRC who underwent PTR or attempted SEMS placement.

Optimal extent of lymph node dissection in clinical early-stage right colon cancer: a retrospective analysis.

Purpose: Determining the extent of radical lymphadenectomy at clinical early stage is challenging. We aimed to investigate the appropriate extent of lymphadenectomy in clinical early-stage right colon cancer.

Methods: Patients with clinical stage 0 or I right colon cancer who underwent curative surgery from January 2007 to December 2021 were included in this retrospective study.

Colorectal metastasis from gastric cancer: insights from a 14-year case series at a tertiary hospital.

Background: Colorectal metastasis from gastric cancer is very rare, with existing literature limited to only a few case reports. This study was designed to investigate the clinicopathological features and prognosis of colorectal metastasis arising from gastric cancer.

Methods: Patients with colorectal metastasis from gastric cancer who underwent surgical intervention at a single tertiary hospital between January 2010 and June 2023 were included, and their clinicopathological characteristics and oncologic outcomes were analyzed.

Efficacy of Neoadjuvant Hypofractionated Chemoradiotherapy in Elderly Patients with Locally Advanced Rectal Cancer: A Single-Center Retrospective Analysis.

: The application of long-course chemoradiotherapy (LCRT) in elderly patients with locally advanced rectal cancer (LARC) can be challenging due to increased risks of complications associated with comorbidities and reduced functional status. This study aimed to assess the efficacy of neoadjuvant hypofractionated chemoradiotherapy (HCRT) in elderly patients with mid-to-low LARC. : We performed a retrospective review of patients diagnosed with LARC from January 2013 to December 2020 and included those aged 70 years or older.

Intravenous versus oral iron supplementation for iron deficiency anemia in patients with rectal cancer undergoing neoadjuvant chemoradiotherapy: a study protocol for a randomized controlled trial.

Background: Numerous studies have been conducted to manage anemia in surgical patients through iron supplementation as an alternative to blood transfusion. However, patients with locally advanced rectal cancer have often been excluded from these studies, due to their standard treatment involving neoadjuvant chemoradiotherapy. This study aims to evaluate the impact of intravenous versus oral iron supplementation on iron deficiency anemia in patients with rectal cancer receiving preoperative chemoradiotherapy.

Comparative analysis of organ preservation attempt and radical surgery in clinical T2N0 mid to low rectal cancer.

Purpose: Debate persists regarding the feasibility of adopting an organ-preserving strategy as the treatment modality for clinical T2N0 rectal cancer. This study aimed to compare the outcomes of attempting organ-preserving strategies versus radical surgery in patients with clinical T2N0 mid to low rectal cancer.

Methods: Patients diagnosed with clinical T2N0 rectal cancer, with lesions located within 8 cm from the anal verge as determined by pre-treatment magnetic resonance imaging between January 2010 and December 2020 were included.

Colon cancer: the 2023 Korean clinical practice guidelines for diagnosis and treatment.

Colorectal cancer is the third most common cancer in Korea and the third leading cause of death from cancer. Treatment outcomes for colon cancer are steadily improving due to national health screening programs with advances in diagnostic methods, surgical techniques, and therapeutic agents..

Dysbiosis of gut microbiota during fecal stream diversion in patients with colorectal cancer.

Background: The effect of fecal stream diversion on the gut microbiota is still uncertain. The present study was designed to assess the effect of fecal stream diversion on the composition of the gut microbiota in patients with colorectal cancer. We included patients undergoing left-sided colorectal cancer surgery with (ileostomy group) or without (control group) diverting ileostomy.
