The prognostic value of a geriatric risk score for older patients undergoing emergency surgery of colorectal cancer: A retrospective cohort study.

Introduction: Emergency surgery of colorectal cancer is associated with high mortality rates in older patients. We investigated whether information on four geriatric domains has prognostic value for 30-day mortality and postoperative morbidity including severe complications.

Materials And Methods: All consecutive patients aged 70 years or older who underwent emergency colorectal cancer surgery in six Dutch hospitals (2014-2017) were studied.

Near-Infrared Fluorescence Tumor-Targeted Imaging in Lung Cancer: A Systematic Review.

Lung cancer is the most common cancer type worldwide, with non-small cell lung cancer (NSCLC) being the most common subtype. Non-disseminated NSCLC is mainly treated with surgical resection. The intraoperative detection of lung cancer can be challenging, since small and deeply located pulmonary nodules can be invisible under white light.

A Prediction Model for Severe Complications after Elective Colorectal Cancer Surgery in Patients of 70 Years and Older.

Unlabelled: Introduction Older patients have an increased risk of morbidity and mortality after colorectal cancer (CRC) surgery. Existing CRC surgical prediction models have not incorporated geriatric predictors, limiting applicability for preoperative decision-making. The objective was to develop and internally validate a predictive model based on preoperative predictors, including geriatric characteristics, for severe postoperative complications after elective surgery for stage I-III CRC in patients ≥70 years.

Synthetic Versus Biological Mesh in Laparoscopic and Open Ventral Hernia Repair (LAPSIS): Results of a Multinational, Randomized, Controlled, and Double-blind Trial.

Objective: The aim of this study was to investigate the approach (open or laparoscopic) and mesh type (synthetic or biological) in ventral hernias in a clean setting.Summary of Background Data: The level of evidence on the optimal surgical approach and type of mesh in ventral hernia repair is still low.

Methods: Patients with a ventral abdominal hernia (diameter 4-10 cm) were included in this double-blind randomized controlled trial across 17 hospitals in 10 European countries.

Textbook outcome as a composite outcome measure in non-small-cell lung cancer surgery.

Objectives: Quality assessment is an important element in providing surgical cancer care. The main objective of this study was to develop a new composite measure 'textbook outcome', to evaluate and improve quality of surgical care for patients undergoing a resection for non-small-cell lung cancer (NSCLC).

Methods: All patients undergoing an anatomical resection for NSCLC from 2012 to 2016 registered in the nationwide Dutch Lung Cancer Audit were included in an analysis to assess usefulness of a composite measure as a quality indicator.

Surgical treatment of pulmonary metastases in the Netherlands: data from the Dutch Lung Cancer Audit for Surgery.

Objectives: Surgical resection is widely employed as a potential curative treatment option for patients with limited lung metastases originating from a wide range of primary tumours. However, there are no clear national or international practice guidelines and, thereby, the risk for potential practice variation exists. This study aims to define the current practice for the surgical treatment of pulmonary metastases in the Netherlands by using data from the Dutch Lung Cancer Audit for Surgery (DLCA-S).

Physical performance has a strong association with poor surgical outcome in older patients with colorectal cancer.

Background: Low lumbar skeletal muscle mass and density have been associated with adverse outcomes in different populations with colorectal cancer (CRC). We aimed to determine whether skeletal muscle mass, density, and physical performance are associated with postoperative complications and overall survival (OS) in older CRC patients.

Methods: We analysed consecutive patients (≥70 years) undergoing elective surgery for non-metastatic CRC (stage I-III).

Hartmann's procedure versus sigmoidectomy with primary anastomosis for perforated diverticulitis with purulent or faecal peritonitis (LADIES): a multicentre, parallel-group, randomised, open-label, superiority trial.

Background: Previous studies have suggested that sigmoidectomy with primary anastomosis is superior to Hartmann's procedure. The likelihood of stoma reversal after primary anastomosis has been reported to be higher and reversal seems to be associated with lower morbidity and mortality. Although promising, results from these previous studies remain uncertain because of potential selection bias.

The Prognostic Value of a Geriatric Risk Score for Older Patients with Colorectal Cancer.

Introduction: VMS is a Dutch risk assessment tool for hospitalized older adults that includes a short evaluation of four geriatric domains: risk for delirium, risk for undernutrition, risk for physical impairments, and fall risk. We investigated whether the information derived from this tool has prognostic value for outcomes of colorectal surgery.

Methods: All consecutive patients over age 70 years who underwent elective colorectal cancer surgery in three Dutch hospitals (2014-2016) were studied.

MEDIASTinal staging of non-small cell lung cancer by endobronchial and endoscopic ultrasonography with or without additional surgical mediastinoscopy (MEDIASTrial): study protocol of a multicenter randomised controlled trial.

Background: In case of suspicious lymph nodes on computed tomography (CT) or fluorodeoxyglucose positron emission tomography (FDG-PET), advanced tumour size or central tumour location in patients with suspected non-small cell lung cancer (NSCLC), Dutch and European guidelines recommend mediastinal staging by endosonography (endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS)) with sampling of mediastinal lymph nodes. If biopsy results from endosonography turn out negative, additional surgical staging of the mediastinum by mediastinoscopy is advised to prevent unnecessary lung resection due to false negative endosonography findings. We hypothesize that omitting mediastinoscopy after negative endosonography in mediastinal staging of NSCLC does not result in an unacceptable percentage of unforeseen N2 disease at surgical resection.

Dutch Lung Surgery Audit: A National Audit Comprising Lung and Thoracic Surgery Patients.

Background: The nationwide Dutch Lung Surgery Audit (DLSA) started in 2012 to monitor and evaluate the quality of lung operations in The Netherlands as an improvement tool. This outline describes the establishment, structure, and organization of the audit by the Dutch Society of Lung Surgeons (NVvL) and the Dutch Society of Cardiothoracic Surgeons (NVT), in collaboration with the Dutch Institute for Clinical Auditing. In addition, the first 4-year results are presented.

Risk stratification for surgical outcomes in older colorectal cancer patients using ISAR-HP and G8 screening tools.

Background: Older patients are at risk for adverse outcomes after surgical treatment of cancer. Identifying patients at risk could affect treatment decisions and prevent functional decline. Screening tools are available to select patients for Geriatric Assessment.

Differences between colon and rectal cancer in complications, short-term survival and recurrences.

Purpose: Many apparent differences exist in aetiology, genetics, anatomy and treatment response between colon cancer (CC) and rectal cancer (RC). This study examines the differences in patient characteristics, prevalence of complications and their effect on short-term survival, long-term survival and the rate of recurrence between RC and CC.

Methods: For all stage II-III CC and RC patients who underwent resection with curative intent (2006-2008) in five hospitals in the Netherlands, occurrence of complications, crude survival, relative survival and recurrence rates were compared.

Association Between the Most Frequent Complications After Surgery for Stage I-III Colon Cancer and Short-Term Survival, Long-Term Survival, and Recurrences.

Background: The purpose of this study was to identify the ten most frequent complications after surgery for stage I-III colon cancer and to assess the association between these complications and overall survival, conditional overall survival, and recurrences.

Methods: All patients who underwent surgery for stage I-III colon cancer in five hospitals in the Western region of the Netherlands were identified. Crude and adjusted Cox proportional hazards models were used to study the association between complications and 1-year overall survival, 5-year overall survival, 5-year conditional overall survival, and 5-year disease-free period.

Adjuvant chemotherapy for rectal cancer patients treated with preoperative (chemo)radiotherapy and total mesorectal excision: a Dutch Colorectal Cancer Group (DCCG) randomized phase III trial.

Background: The discussion on the role of adjuvant chemotherapy for rectal cancer patients treated according to current guidelines is still ongoing. A multicentre, randomized phase III trial, PROCTOR-SCRIPT, was conducted to compare adjuvant chemotherapy with observation for rectal cancer patients treated with preoperative (chemo)radiotherapy and total mesorectal excision (TME).

Patients And Methods: The PROCTOR-SCRIPT trial recruited patients from 52 hospitals.

Guidelines-based diagnostic process does increase hospital delay in a cohort of colorectal cancer patients: a population-based study.

This is an investigation of factors determining hospital delay until treatment in an unrestricted population of colorectal cancer patients in the western part of the Netherlands. All patients with newly diagnosed colon (n=2146) and rectal carcinoma (n=1036) in the period 2006-2008 were included in analyses of inhospital delay (first hospital visit until first treatment >35 days). One-third of all patients were also available for analyses of prehospital delay (enrollment until first hospital visit >7 days).

The DULK (Dutch leakage) and modified DULK score compared: actively seek the leak.

Aim: A standardized postoperative score, the DULK (Dutch leakage) score, has been demonstrated to be a useful clinical tool in the diagnosis of anastomotic leakage. It is complicated, however, and a simplification (the modified DULK score) based on fewer parameters derived from multiple logistic regression analyses has been developed. These include clinical condition, abdominal pain not localized at the wound, C-reactive protein level and respiratory rate.

The ladies trial: laparoscopic peritoneal lavage or resection for purulent peritonitis and Hartmann's procedure or resection with primary anastomosis for purulent or faecal peritonitis in perforated diverticulitis (NTR2037).

Background: Recently, excellent results are reported on laparoscopic lavage in patients with purulent perforated diverticulitis as an alternative for sigmoidectomy and ostomy.The objective of this study is to determine whether LaparOscopic LAvage and drainage is a safe and effective treatment for patients with purulent peritonitis (LOLA-arm) and to determine the optimal resectional strategy in patients with a purulent or faecal peritonitis (DIVA-arm: perforated DIVerticulitis: sigmoidresection with or without Anastomosis).

Methods/design: In this multicentre randomised trial all patients with perforated diverticulitis are included.

Improved diagnosis and treatment of soft tissue sarcoma patients after implementation of national guidelines: a population-based study.

Aim: The majority of clinicians, radiologists and pathologists have limited experience with soft tissue sarcomas. In 2004, national guidelines were established in The Netherlands to improve the quality of diagnosis and treatment of these rare tumours. This study evaluates the compliance with the guidelines over time.

Centralization of esophageal cancer surgery: does it improve clinical outcome?

Background: The volume-outcome relationship for complex surgical procedures has been extensively studied. Most studies are based on administrative data and use in-hospital mortality as the sole outcome measure. It is still unknown if concentration of these procedures leads to improvement of clinical outcome.
