Hepatic arterial therapy with oxaliplatin and systemic capecitabine for patients with liver metastases from breast cancer.

OBJECTIVES: Hepatic arterial treatment (HAT) for liver metastases in patients with metastatic breast cancer (MBC) has only been investigated in few studies. MATERIALS AND METHODS: Two phase II trials were initiated simultaneously to evaluate capecitabine in combination with oxaliplatin in patients with MBC and liver metastases. These two trials are reported together. Continuous capecitabine (1300 mg/m2) was combined with oxaliplatin (85 mg/m2) alternating between systemic treatment and HAT followed by degradable starch microspheres with EmboCept® S every second week. Four patients participated in a pharmacokinetic analysis of oxaliplatin. Each patient had samples taken when receiving oxaliplatin systemically and as HAT with and without EmboCept® S. RESULTS: Totally, 52 patients received HAT: 14 with liver metastases only and 38 patients with additional limited metastatic disease. The patients had previously received a median of 2 (range 0-6) chemotherapeutic regimens for MBC. The response rate was 42.3% (95% confidence interval (CI) 28.7-56.8%) with 7.7% complete and 34.6% partial responses. Median progression free survival was 10.8 months (95% CI 6.9-14.7 months) and median overall survival 27.6 months (95% CI 20.4-34.8 months). The toxicity was moderate with hand-foot syndrome (15.4%), neuropathy (9.6%), fatigue (9.6%), and abdominal pain (9.6%) being the most common grade 3 adverse events. There was no clear difference between systemic blood concentrations of oxaliplatin when given systemic or as HAT. CONCLUSION: HAT oxaliplatin in combination with capecitabine is safe and efficient in patients with MBC. The results are promising with high response rates and a long median progression free and overall survival.

[Occurrence of renal artery stenosis in patients with peripheral arteriosclerosis and hypertension]. / Forekomst af nyrearteriestenose hos patienter med perifer arteriosklerose og hypertension.

The aim of this study was to evaluate the prevalence of renal artery stenosis in patients with clinical signs of peripheral vascular disease and hypertension. One hundred patients, mean age 69 years (range 45-88) with symptoms and clinical signs of severe peripheral ischaemia, underwent aortography to determine the degree of peripheral vascular disease and possible renal artery stenosis. History of claudication and measurement of systolic distal blood pressure and calculation of the Ankle Brachial Index was used to define the severity of peripheral vascular disease. Thirty-one percent had renal artery stenosis (14% greater than 50% reduction in luminal diameter). In a subgroup of patients with hypertension and peripheral vascular disease (n = 74), 34% had renal artery stenosis. In the subgroup of patients with renal artery stenosis, 81% had hypertension. Among patients with renal artery stenosis and lumen reduction of more than 50%, 93% had hypertension (p < 0.001). In conclusion this study shows that the combination of peripheral vascular disease and hypertension is an important clinical clue for renovascular disease. Examination for renovascular disease in this population should be considered, since the prevalence of the condition is high. Furthermore, examination for renal vascular disease in this population is mandatory, before treatment with angiotensin converting enzyme inhibitors is initiated, since treatment might lead to serious renal function impairment.

Inflammatory aortic aneurysms: regression of fibrosis after aneurysm surgery.

OBJECTIVES: To evaluate the fate of perianeurysmal fibrosis (PF) following aneurysm surgery. METHODS: In this single centre study, pre- and postoperative abdominal CT-scans on 21 consecutive patients with inflammatory abdominal aortic aneurysms were compared. CT-scans of 10 randomly chosen patients operated on for abdominal aortic aneurysms without PF in the same period, served as reference group. RESULTS: Preoperative thickness of PF was assessed as > 1 cm in 11 and < 1 cm in 10 patients. Ureterolysis was performed in seven patients where the fibrosis caused ureteral obstruction. Postoperative CT-scans performed at a median of 24 (range 3-108) months after surgery showed complete regression of the fibrosis in 29%, partial regression in 57% and no change in 14% of the patients. Progression of the fibrosis or persistence of hydronephrosis was not seen. No sign of fibrosis were seen in the 10 controls. CONCLUSION: This study supports the findings that PF tends to regress after repair of the abdominal aortic aneurysm.

[Occupational and educational conditions of young radiologists]. / Yngre radiologers arbejds- og uddannelsesforhold.

A questionnaire containing 56 questions on educational activities and occupational preferences was sent to postgraduate trainees at all Departments of Diagnostic Radiology in Denmark. Answers were received from 154 individuals or 63% of the trainees. Trainees at University departments assessed the daily educational activities as less satisfactory than did trainees at other departments. Financial support for educational courses was less often given to trainees from the eastern region including the capital than to trainees from the rest of the country. Evaluation interviews, made in order to assess the trainee's progress, had been attended by 22%. Fifty-nine % of these interviews resulted in alteration of the trainee's working programme. If appropriate for their career, 82% would apply for an appointment requiring changing their address.
