AIM: In 2014, a national colorectal cancer (CRC) screening program was launched in the Netherlands. It is difficult to assess for the individual CRC patient whether the oncological benefits of surgery will outweigh the morbidity of the procedure, especially in early lesions. This study compares patient and tumour characteristics between screen-detected and non-screen-detected patients. Secondly, we present an overview of treatment options and clinical dilemmas when treating patients with early stage colorectal disease...

BACKGROUND: Preoperative low skeletal muscle mass and density are associated with increased postoperative morbidity in patients undergoing curative colorectal cancer (CRC) surgery. However, the long-term effects of low skeletal muscle mass and density remain uncertain. METHODS: Patients with stage I-III CRC undergoing surgery, enrolled in a prospective observational cohort study, were included. Skeletal muscle mass and density were measured on CT. Patients with high and low skeletal muscle mass and density were compared regarding postoperative complications, disease-free survival (DFS), overall survival (OS), and cancer-specific survival (CSS)...

BACKGROUND: To stage axillary lymph nodes in women with early-stage breast cancer, sentinel lymph node biopsy (SLNB), rather than axillary lymph node dissection (ALND), has been employed. Moreover, different tracer methods have various advantages and disadvantages. In recent years, carbon nanoparticle suspensions (CNSs) have been used as lymph node tracers during surgeries for thyroid cancer, gastric cancer, and colorectal cancer. The study retrospectively analyzed the feasibility and accuracy of CNS for sentinel lymph node (SLN) mapping in patients with early breast cancer...

Accurate prediction of regional lymph node metastases (LNM) in endoscopically resected pT1 colorectal cancer (CRC) is crucial in treatment stratification for subsequent radical surgery. Several miRNAs have been linked to CRC invasion and metastasis, including the oncogenic miR-17/92 cluster, and expression levels might have predictive value in the risk assessment of early metastatic progression in CRC. We performed global miRNA microarray using tissue samples from the invasive front of pT1 CRC and investigated associations of the miR-17/92 cluster and presence of LNM...

Backgrounds/Aims: This study attempted to identify risk factors for development of post-hepatectomy hepatic failure (PHF) and its effect on long-term survival of patients with liver metastases from colorectal cancer. Methods: We carried out a retrospective study of 143 patients who had been diagnosed with liver metastases from colorectal cancer and who had undergone hepatectomy between 2003 and 2010. We allocated these patients to PHF and non-PHF groups, using the definition of the International Study Group of Liver Surgery, and compared the clinical factors of the two groups, using Cox regression and Kaplan-Meier analysis to evaluate the differences in overall survival (OS) and recurrence-free survival (RFS) between these groups...

BACKGROUND: The assessment and evaluation of practical and sustainable development of health care has become a major focus of investigation in health services research. A key challenge for researchers as well as decision-makers in health care is to understand mechanisms influencing how complex interventions work and become embedded in practice, which is significant for both evaluation and later implementation. In this study, we explored nurses' and surgeons' perspectives on performing and participating in a complex multi-centre person-centred intervention process that aimed to support patients diagnosed with colorectal cancer to feel prepared for surgery, discharge and recovery...

BACKGROUND: Complete mesocolic excision (CME) has been proposed for colon cancer to improve oncological outcomes. The risks and benefits of laparoscopic CME have not been examined fully. We compared short- and long-term outcomes of CME with a conventional mesocolic excision (non-CME) in laparoscopic right hemicolectomy (RHC) for right-sided colon cancer. METHODS: In total, 115 patients who underwent laparoscopic RHC with stage I-III right-sided colon cancer at Busan Paik Hospital from August 2007 to October 2011 were enrolled in this case-control study...

PURPOSE: Hospital readmissions after surgery are a focus of quality improvement efforts. Although some reflect appropriate care, others are potentially preventable readmissions (PPRs). We aim to describe the burden, timing, and factors associated with readmissions after complex cancer surgery. METHODS: The Nationwide Readmissions Database (2013) was used to select patients undergoing a complex oncologic resection, which was defined as esophagectomy/gastrectomy, hepatectomy, pancreatectomy, colorectal resection, lung resection, or cystectomy...

The presence of tumor deposits (TD) in colorectal cancer (CRC) is associated with poor prognosis. The 7th edition of TNM subclassified a new nodal stage, N1c, characterized by the presence of TD without any concurrent positive lymph node (LN). It is not clear if the N1c category is equal or not to LN metastasis. We aimed to examine the prevalence, characteristics and prognostic significance of this new subcategory METHODS: Consecutive patients who underwent surgery for CRC in two centers (2011-2014) were analyzed...

<i>Objective:</i> Intestinal anastomotic failure that occurs mainly due to ischaemia is a serious risk in colorectal cancer patients undergoing surgery. Surgeons continue to rely on subjective methods such as visual inspection to assess intestinal viability during surgery and there are no clinical tools to directly monitor viability postoperatively. A dual wavelength, reflectance optical sensor has been developed for continuous and dynamic monitoring of intestinal viability via the intestinal lumen...

Background: It is unclear whether emergency weekend colon and rectal cancer surgery are associated with worse outcomes (ie, weekend effect) because previous studies mostly used administrative data, which may insufficiently adjust for case-mix. Materials and Methods: Prospectively collected data from the 2012-2015 Dutch ColoRectal Audit (n=5,224) was used to examine differences in 30-day mortality and severe complication and failure-to-rescue rates for emergency weekend (Saturday and Sunday) versus Monday surgery, stratified for colon and rectal cancer...

Colorectal cancer (CRC) is a frequently occurring disease, yet diagnosed at a local stage in only 40% of cases. Lung metastases (LM) appear in 5-15% of patients and, left untreated, carry a very poor prognosis. Some CRC patients may benefit from a potentially curative LM resection, but success and benefit are difficult to predict. We discuss prognostic factors of survival after lung metastasectomy in CRC patients under several scenarios (with/ without prior liver metastases; repetitive pulmonary resections)...

Objective: Patients with stage III and high-risk stage II colorectal cancer (CRC) are advised to initiate adjuvant treatment as soon as feasible and certainly before 8 to 12 weeks after resection of the tumor. A protective ileostomy is often constructed during surgery to protect a primary anastomosis "at risk", especially in rectal cancer surgery. However, up to 17% of patients with a stoma suffer from high output, a major complication that can prevent adjuvant treatment implementation or completion...

INTRODUCTION: Clinical practice guidelines (CPGs) support enhanced post-operative recovery and decrease morbidity. In addition, patient information leaflets (PILs) are associated with enhanced overall outcomes and improved patient satisfaction. The aim of this study was to provide an overview of the quality of CPGs and PILs in cancer surgery departments undertaking pulmonary lobectomy, nephrectomy, cystectomy, whipples, colorectal and ovarian surgery. METHODS: We conducted a cross-sectional descriptive study within 44 surgical departments in six cancer subspecialties: lung (n = 4), kidney (n = 9), bladder (n = 5), pancreas (n = 4), colorectal (n = 18) and ovarian (n = 4)...
