Magnetic resonance imaging in size assessment of invasive breast carcinoma with an extensive intraductal component

BackgroundBreast-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.Methods23 patients were identified and the mammographic (n = 21) and MR (n = 23) images were re-reviewed by a senior radiologist. Size on MR images was compared with histopathological tumour extent.ResultsThe correlation of radiological size with histopathological size was r = 0.20 in mammography (p = 0.39) compared to r = 0.65 in MRI (p < 0.01). Mammography underestimated histopathological tumour size in 62%. MR images over- or underestimated tumour size in 22% and 30% of the cases, respectively. In poorly differentiated EIC, MRI adequately estimated the extent more often compared to moderately differentiated EIC (60% versus 25%, respectively).ConclusionSize assessment of MRI imaging was more accurate compared to mammography. This was predominantly true for poorly differentiated EIC.

Local Recurrences After Conservative Treatment of Ductal Carcinoma-In-Situ of the Breast Without Radiotherapy: The Effect of Age

BackgroundThe 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.MethodsA total of 499 female patients with 502 DCIS lesions treated in the period 1989 to 2002 were retrospectively reviewed. Survival rates were calculated by the Kaplan-Meier method, and differences were tested by using the log-rank test. The association of variables with local recurrence was analyzed by using the χ2 test.ResultsTreatment constituted of lumpectomy in 329 patients (65%). Thirty-eight patients (8%) had disease-positive margins, and for 41 patients (8%) the margin status was not known. Eighty tumors recurred, for a local recurrence rate of 13% after 4 years compared with 17% for patients treated with breast-conserving surgery only. Risk factors for ipsilateral recurrences were younger age (<50 years), treatment with breast-conserving surgery only, and presence of disease-involved surgical margins.ConclusionsConservative treatment of DCIS results in high recurrences rates, and outcomes can be improved by performing more radical surgery. Because radiotherapy has been shown to be effective in preventing recurrent disease, and, to date, no subgroups have been identified in which radiation can be omitted, its use is recommended, especially in younger patients.

Hemobilia as a Late Complication After Blunt Abdominal Trauma: A Case Report and Review of the Literature

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. Angiography revealed a pseudoaneurysm of the right hepatic artery, which was successfully treated with embolization. CONCLUSIONS The diagnosis of hemobilia first requires consideration of the diagnosis, particularly in patients with previous abdominal trauma. Hemobilia should be included in the differential diagnosis of upper gastrointestinal bleeding. Investigations of choice include computed tomography scan followed by angiography. During angiography, treatment can be done by endovascular embolization.

Persisting Iliaco-Caval Fistula After EVAR Maintained by a Type II Endoleak

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.

Spontaneous regression of a cystic retroperitoneal tumour in young women postpartum. Report of two cases.

Retroperitoneal cystic tumours are rarely found, and of these, the most common lesion is a cystic lymphangioma. We present two postpartum patients with a cystic retroperitoneal tumour which showed spontaneous regression and a review of the literature.

Aberrant Insertion of the Right Subclavian Artery: an Unusual Cause of Dysphagia in an Adult

IntroductionWithin this report, we present a patient with difficulty of swallowing caused by an aberrant right subclavian artery.DiscussionThis 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.

Clinical presentation and surgical quality in treatment of ductal carcinoma in situ of the breast

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 = 0.01). Finally, 65% of patients underwent breast-conserving surgery and 35% of patients a mastectomy (no significant differences between the two types of hospitals). In teaching hospitals 19% of the patients had a disease-involved or unknown surgical margins versus 13% in non-teaching hospitals (p = 0.04). Twenty patients (4%) received radiation therapy postoperatively with no differences between teaching and non-teaching hospitals (p = 0.98).Quality of surgical treatment is the most important prognostic factor in treatment of DCIS. The quality of excisions should be improved and the exact status of margins should be recorded in pathology reports.
