RESUMO
Aneurysms of the renal artery and its branches are rare, but are associated with significant morbimortality due to the absence of clinical symptoms and hemorrhagic risk in the event of rupture. We report the case of a patient with an aneurysm of a distal branch of the right renal artery that measured 25 mm in diameter. The diagnosis and localization were obtained using selective arteriography. Treatment consisted of resection of the aneurysmal sac associated with closure with a saphenous vein patch rather than an endovascular treatment in order to preserve the nephronic capital. Right renal parenchymatous vascularization was satisfactory on arterial echo-Doppler and angioscanner assessment at 1 year.

PURPOSE: Bone metastases (BM) and skeletal-related events (SRE) are frequent in patients with malignant pheochromocytoma and paraganglioma (PPM) and the best modality of prevention unknown. The role of interventional radiology (IR) techniques for the prevention of SRE in the multidisciplinary management of malignant PPM has not been evaluated in that setting. METHODS: Single referral center retrospective review of all patients with malignant PPM with BM from 2000 to 2016. The primary endpoint was the time to first serious SRE (TTSRE). At time of inclusion, patients with high bone tumor burden disease were defined as those having more than five BM with the biggest exceeding 2 cm (Group A) and patients with moderate bone tumor burden disease were defined as those having five or less BM or no BM exceeding 2 cm (Group B). RESULTS: A total of 28 patients were included in this study. Thirteen were treated by IR techniques for prevention of first serious SRE. After a median follow-up of 48.2 months, the median TTSRE was not reached in patients treated by IR techniques and was 26.0 months in patients without IR procedures (p = .058). When comparing patients in group B, TTSRE was significantly higher in patients treated by IR (10 patients) when compared to patients without IR procedures (12 patients) (p = .021). CONCLUSIONS: IR techniques may help to delay the occurrence of first serious SRE in patients with malignant PPM with moderate bone tumor burden disease. Prospective studies are expected to confirm these results.

BACKGROUND: Recommended treatments of patients with advanced biliary tract cancer (aBTC) are limited to one chemotherapy doublet. Nevertheless, efficacy of treatment personalisation for aBTCs is supported by accumulating evidences but remains to be evaluated. PATIENTS AND METHODS: Patients with aBTCs included in the prospective clinical trial MOSCATO-01 were treated by at least one previous systemic treatment, had an ECOG performance status of 0-1, and at least one tumour site accessible to biopsy. Multiple high-throughput molecular analysis was performed on biopsies to drive the administration of molecular targeted agents (MTAs). RESULTS: From November 2011 to March 2016, 43 patients (4%) of the 1035 adult patients included in MOSCATO-01 had aBTCs with a majority of intrahepatic localisation (67%). Successful biopsy procedures and DNA extractions led to molecular portraits for 34 patients (79%). Orientation to an appropriate early clinical trial or accessible MTA(s) was possible for 23 of these patients (68%), and 18 (53%) have received matched MTA(s). Among them, the overall response rate was 33% and the disease control rate was 88%. A PFS ≥6 months was observed in 37% and the PFS ratio was >1.3 for 50% of the patients. These patients had a lower risk for death as compared to the 20 patients not orientated to a matched MTA (HR, 0.29; 95% CI, 0.11-0.76; p = 0.008). CONCLUSIONS: Within the MOSCATO-01 trial, patients with aBTCs had the highest rate of orientation to matched MTAs and derived a clear clinical benefit. A broader evaluation of these findings may improve future treatments strategies for aBTCs. TRIAL REGISTRATION: NCT01566019.
