- BACKGROUND: Emerging data support the use of thymidine kinase 1 (TK1) activity as a prognostic marker and for monitoring of response in breast cancer (BC). The long-term prognostic value of TK1 kinetics during neoadjuvant chemotherapy is unclear, which this study aimed to elucidate. METHODS: Material from patients enrolled to the single-arm prospective PROMIX trial of neoadjuvant epirubicin, docetaxel and bevacizumab for early BC was used. Ki67 in baseline biopsies was assessed both centrally and by automated digital imaging analysis. TK1 activity was measured from blood samples obtained at baseline and following two cycles of chemotherapy. The associations of TK1 and its kinetics as well as Ki67 with event-free survival and overall survival (OS) were evaluated using multivariable Cox regression models. RESULTS: Central Ki67 counting had excellent correlation with the results of digital image analysis (r= 0.814), but not with the diagnostic samples (r= 0.234), while it was independently prognostic for worse OS [adjusted hazard ratio (HRadj) = 2.72, 95% confidence interval (CI) 1.19-6.21, P= 0.02]. Greater increase in TK1 activity after two cycles of chemotherapy resulted in improved event-free survival (HRadj= 0.50, 95% CI 0.26-0.97, P= 0.04) and OS (HRadj= 0.46, 95% CI 0.95, P= 0.04). There was significant interaction between the prognostic value of TK1 kinetics and Ki67 (pinteraction 0.04). CONCLUSION: Serial measurement of serum TK1 activity during neoadjuvant chemotherapy provides long-term prognostic information in BC patients. The ease of obtaining serial samples for TK1 assessment motivates further evaluation in larger studies. Copyright © 2021 The Author(s). Published by Elsevier Ltd.. All rights reserved.

Assessing endovascular skills using the Simulator for Testing and Rating Endovascular Skills (STRESS) machine

- OBJECTIVES: Endovascular techniques are an integral part of modern-day vascular surgery practice and training. Nevertheless, validated in vitro assessment tools for these skills are scarce. This study describes the development and pilot testing of the Simulator for Testing and Rating Endovascular Skills (STRESS machine). DESIGN: The design was kept straightforward and compact, without the need for contrast or fluoroscopy. A specific technical skill score was designed analogous to the Imperial College Evaluation of Procedural Skill (ICEPS), an assessment score for open surgical skill. This score was combined with an already validated global rating assessment to form the total score (TS). METHODS: A pilot study was carried out on 18 candidates of varying levels of expertise: novice, intermediate and expert, who were assessed by two independent observers to test inter-observer reliability. RESULTS: Inter-observer reliability was excellent, Cronbach's alpha coefficient of the TS was 0.94 (95% confidence interval: 0.84-0.97). A one-way analysis of variance (ANOVA) showed a significant difference between the novice and expert groups (p<0.001), between the novice and intermediate groups (p<0.01) and between the intermediate and expert groups (p<0.05). CONCLUSION: The STRESS machine, in combination with the specific technical skill score and global rating assessment, provides a reliable method of discriminating between the novice, intermediate and expert candidates with excellent inter-observer variability.

Secondary aortoenteric fistula : changes from 1973 to 1993
- 1996

- AIM: To investigate a series of patients with secondary aortoenteric fistulas and compare it with a previous series (1985-93 vs. 1973-84). DESIGN: Retrospective study of medical records. SETTING: Sixteen vascular surgical centers in Sweden. PATIENTS: Twenty-seven patients were identified making an overall incidence of 0.5% of all aortoiliac operations. Among aneurysm patients the incidence was significantly lower than in the previous series. One patient record could not be identified. Fourteen primary operations were for aortic aneurysm, 12 for occlusive disease and one was an aortorenal vein bypass. RESULTS: Symptoms of the fistula occurred after a median interval of 90 months which is significantly later than the previous series (32 months; p<0.05). The commonest presentation was bleeding followed by septis. The median diagnostic delay was 10.5 days, which was significantly shorter than in the previous series. Most fistulas involved the duodenum (88%). One patient died before surgery. The postoperative mortality was 28%, significantly lower than in the previous series (58%) (p<0.05). At the end of follow up (median 43 months) significantly more patients were alive than in the previous series (42% vs 18%) (p<0.05). CONCLUSION: Over a 21 year period there seems to have been a decrease in the frequency of secondary aortoenteric fistulas after aneurysm surgery, a longer interval before they occur, a shorter diagnostic delay, and a better survival.
