Leiomyosarcoma of the renal vein

Background Leiomyosarcoma is a rare malignant mesenchymal tumour. Some cases of leiomyosarcoma of the renal vein (LRV) have been reported in the literature, but no analysis of data and search for prognostic factors have been done so far. The aim of this review was to describe the LRV, to analyse overall survival (OS), local recurrence free survival (LRFS) and distant metastases free survival (DMFS) in LRV world case series and to identify significant predictors of OS, LRFS and DMFS. Methods Cases from the literature based on PubMed search and a case from our institution were included. Results Sixty-seven patients with a mean age of 56.6 years were identified76.1% were women. Mean tumour size was 8.9 cmin 68.7% located on the left side. Tumour thrombus extended into the inferior vena cava lumen in 13.4%. All patients but one underwent surgery (98.5%). After a median follow up of 24 months, the OS was 79.5%. LRFS was 83.5% after a median follow up of 21.5 months and DMFS was 76.1% after a median follow up of 22 months. Factors predictive of OS in univariate analysis were surgical margins, while factors predictive of LRFS were inferior vena cava luminal extension and grade. No factors predictive of DMFS were identified. In multivariate analysis none of the factors were predictive of OS, LRFS and DMFS. Conclusions Based on the literature review and presented case some conclusions can be made. LRV is usually located in the hilum of the kidney. It should be considered in differential diagnosis of renal and retroperitoneal masses, particularly in women over the age 40, on the left side and in the absence of haematuria. Core needle biopsy should be performed. Patients should be managed by sarcoma multidisciplinary team. LRV should be surgically removed, with negative margins

The Society of Abdominal Radiology at 10 Years: Reflections, Status Report, and Look to the Future

In 2012, the Society of Abdominal Radiology (SAR) was formed by the merger of the Society of Gastrointestinal Radiologists (SGR) and the Society of Uroradiology (SUR). On the occasion of SAR\u27s ten year anniversary, this commentary describes important changes in society structure, the growth and diversity of society membership, new educational and research initiatives, intersociety and international outreach, and plans for the future

Benefits of a resident-run orientation for new radiology trainees

Incoming radiology residents must rapidly assimilate large amounts of technical, medical, and operational information. This can be overwhelming and contribute to anxiety. Typical introductory curricula focused on radiologic content may not address the concerns of new residents. Two consecutive classes of incoming radiology residents participated in our study. For groups A (n=11) and B (n=11), the existing introductory lectures were given by faculty. For group B, residents hosted sessions for each rotation, including round-table discussions and work area tours, with emphasis on resident roles, personnel, and workflow. With institutional review board exemption, residents were anonymously surveyed before and after the sessions regarding: awareness of responsibilities, familiarity with anatomy, and anxiety regarding each rotation on a 1-4 scale. Free-text comments were collected. Comparison was performed using Wilcoxon rank sum test. Group A reported increased role awareness (P=0.04), greater content familiarity (P<0.05), and decreased anxiety (P=0.02) in one rotation each. There were 3 of 12 rotations in group B that showed significantly increased role awareness (P range <0.01 to 0.01) and decreased anxiety (P range <0.01 to <0.05). In addition, two rotations indicated improved role awareness only (P=0.02 and P=0.04), while there were four rotations reported decreased anxiety only (P range 0.01 to 0.03). Free-text commenters preferred the resident-run portions of the sessions. In conclusion, adding role-oriented introductory sessions to existing lectures for first-year residents decreased anxiety and increased role awareness for all rotations; therefore, it is suggested that anxiety may be better addressed by role-oriented content, and resident-to-resident teaching may have benefits
