A rare subpopulation of cancer cells, termed cancer stem cells (CSCs), may be responsible for tumor relapse and resistance to conventional chemotherapy. The development of a non-toxic, natural treatment for the elimination of CSCs is considered a strategy for cancer treatment with minimal side effects. In the present study, the potential for Sasa quelpaertensis leaf extract (SQE) and its two bioactive compounds, tricin and p-coumaric acid, to exert anti-CSC effects by suppressing cancer stemness characteristics were evaluated in colon cancer cells. CD133+CD44+ cells were isolated from HT29 and HCT116 cell lines using flow-activated cell sorting (FACs). SQE treatment was found to significantly suppress the self-renewal capacity of both cell lines. SQE treatment was also associated with the down-regulation of β-catenin and phosphorylated GSK3β, while significantly enhancing cell differentiation by up-regulating CK20 expression and blocking the expression of several stem cell markers, including DLK1, Notch1, and Sox-2. In vivo, SQE supplementation suppressed tumor growth in a xenograft model by down-regulating stem cell markers and β-catenin as well as HIF-1α signaling. Compared with two bioactive compounds of SQE, SQE exhibited the most effective anti-CSC properties. Taken together, these results provide evidence that SQE inhibits colon cancer by regulating the characteristics of CSCs.

Background: Appendiceal adenocarcinomas and low-grade appendiceal mucinous neoplasms (LAMNs) are rare tumours. Much of the existing knowledge is derived from registry-based studies, particularly the Surveillance, Epidemiology, and End Results database in the USA.
Methods: This retrospective cohort study used data from the Swedish Cancer Registry, Swedish Cause of Death Registry, and the National Patient Registry to analyse demographic characteristics and outcomes of patients diagnosed with appendiceal adenocarcinoma or LAMN between 2005 and 2019.

Objective: To evaluate diagnostic significance of IL-6 compared to CRP for early detection of anastomotic leakage after colon resection for colorectal cancer.
Material And Methods: The study included 277 patients who underwent total resection for colorectal cancer. Patients were retrospectively divided into three groups: without complications (=227), with anastomotic leakage (=30), and other postoperative complications (=20).

Background: Anal squamous cell cancer incidence has risen 2.2% each year over the past decade. Current screening includes anal cytology and high-resolution anoscopy but is burdened with sampling error and patient discomfort.

Introduction: Patients with chronic kidney disease (CKD) face unique challenges in cancer treatment, including the need for chemotherapy dose adjustments and avoiding nephrotoxic agents, often leading to less aggressive treatment. However, little is known about the real-world administration of adjuvant chemotherapy for patients with CKD. In this study, we aimed to investigate the prevalence of adjuvant chemotherapy in patients with CKD and to explore factors influencing chemotherapy use.

Aims: To determine the optimal extent of lymph node dissection for non-metastatic colon cancer by tumor location based on the therapeutic value index (TVI) for each lymph node station.
Methods: Consecutive patients with surgical stage I-III colon or rectosigmoid cancer in the Japanese Society for Cancer of the Colon and Rectum database who underwent curative resection between January 2003 and December 2014 were analyzed. The TVI was defined as the incidence of lymph node metastasis multiplied by 5-year overall survival and calculated for each nodal station stratified by tumor location.
