Regular physical activity (PA) is associated with improved overall survival (OS) in stage I-III colorectal cancer (CRC) patients. This association is less defined in patients with metastatic CRC (mCRC). We therefore conducted a study in mCRC patients participating in the Prospective Dutch Colorectal Cancer cohort.

Background: Parastomal hernias are a frequent complication of enterostomies that require surgical treatment in approximately half of patients. This systematic review aimed to evaluate and compare the safety and effectiveness of the surgical techniques available for parastomal hernia repair.

Methods: Systematic review was performed in accordance with PRISMA.

We present the case of a patient with a persisting type II endoleak after endovascular repair of an iliac aneurysm with an iliaco-caval fistula. We describe the pathophysiological mechanism behind this phenomenon and discuss why conservative treatment is unlikely to seal this type of endoleak. A more aggressive treatment strategy is therefore advocated.

Introduction: Within this report, we present a patient with difficulty of swallowing caused by an aberrant right subclavian artery.

Discussion: This is a congenital anomaly with the right subclavian artery originating from the dorsal part of the aortic arch and coursing through the mediastinum between the esophagus and the vertebral column. The diagnosis and treatment of this disorder is discussed based on the findings from the literature.

Background: After breast-conserving surgery of ductal carcinoma in situ (DCIS) of the breast or invasive breast carcinoma with an extensive intraductal component, tumor-positive surgical margins are frequently found. Therefore, the extent of the intraductal disease needs to be accurately determined preoperatively.

Methods: Data for this review were identified by search of PubMed.

Background: Breast-conserving treatment of invasive breast carcinoma with an extensive intraductal component (EIC) is associated with DCIS-involved surgical margins and therefore it has an increased recurrence rate. EIC is a non-palpable lesion of which the size is frequently underestimated on mammography. This study was undertaken to evaluate the accuracy of MRI in size assessment of breast cancer with EIC.

Background: Bleeding within the biliary tree, called hemobilia, is a rare complication after blunt hepatic trauma.

Objectives: To report on a patient who developed hemobilia 1 month after a blunt abdominal injury and to discuss the diagnosis and treatment of hemobilia.

Case Report: A 17-year-old boy presented with upper gastrointestinal bleeding caused by hemobilia 1 month after a blunt liver injury.

Purpose: Outcomes after different treatment strategies for ductal carcinoma in situ (DCIS) of the breast were analyzed for a geographically defined population in the East Netherlands.

Methods And Materials: A total of 798 patients with a first diagnosis of DCIS between January 1989 and December 2003 were included and their medical records were reviewed. Survival rates for ipsilateral recurrences were calculated by the Kaplan-Meier method and a multivariate Cox proportional hazards regression model was used to evaluate the prognostic significance of different variables.

To assess quality of surgical treatment of ductal carcinoma in situ (DCIS) and to compare teaching and non-teaching hospitals that constitute the Comprehensive Cancer Centres of the Middle Netherlands (IKMN), we retrospectively reviewed 499 patients with 502 DCIS lesions treated in the period 1989-2002. In teaching hospitals fewer patients presented with clinical symptoms compared to non-teaching hospitals (15% versus 24.0%, p = 0.

Background: The value of magnetic resonance imaging (MRI) in diagnosis and size assessment of ductal carcinoma-in-situ (DCIS) and DCIS with small (<10 mm) invasive carcinoma was evaluated.

Methods: Fifty-four patients with DCIS and 12 patients with DCIS and small invasive carcinoma were included. Mammographic (N = 64) and MRI (N = 22) images were retrospectively reviewed.

Background: The main goal in treatment of ductal carcinoma-in-situ (DCIS) of the breast is to prevent local recurrences. Radiotherapy after breast-conserving surgery has been shown to decrease the recurrence rate, although whether all patients should be treated with radiotherapy remains a topic of debate. The aim of this study was to assess the local recurrence rate after conservative surgical treatment of DCIS without radiotherapy and to identify risk factors for local recurrence.

Background: Carcinoma arising in a neovagina is rare.

Case: A patient with an adenocarcinoma arising from a neovagina constructed with use of a sigmoid segment.

Conclusion: Transplanted intestinal tissue should not be overlooked, especially in patients with an increased risk for developing metachronous malignancies.
