Barcelona clinic liver cancer nomogram and others staging/scoring systems in a French hepatocellular carcinoma cohort.

AIM: To compare the performances of the Barcelona clinic liver cancer (BCLC) nomogram and others systems (BCLC, HKLC, CLIP, NIACE) for survival prediction in a large hepatocellular carcinoma (HCC) French cohort. METHODS: Data were collected retrospectively from 01/2007 to 12/2013 in five French centers. Newly diagnosed HCC patients were analyzed. The discriminatory ability, homogeneity ability, prognostic stratification ability Akaike information criterion (AIC) and C-index were compared among scoring systems. RESULTS: The cohort included 1102 patients, mostly men, median age 68 [60-74] years with cirrhosis (81%), child-Pugh A (73%), alcohol-related (41%), HCV-related (27%). HCC were multinodular (59%) and vascular invasion was present in 41% of cases. At time of HCC diagnosis BCLC stages were A (17%), B (16%), C (60%) and D (7%). First line HCC treatment was curative in 23.5%, palliative in 59.5%, BSC in 17% of our population. Median OS was 10.8 mo [4.9-28.0]. Each system distinguished different survival prognosis groups (P < 0.0001). The nomogram had the highest discriminatory ability, the highest C-index value. NIACE score had the lowest AIC value. The nomogram distinguished sixteen different prognosis groups. By classifying unifocal large HCC into tumor burden 1, the nomogram was less powerful. CONCLUSION: In this French cohort, the BCLC nomogram and the NIACE score provided the best prognostic information, but the NIACE could even help treatment strategies.

NIACE score for hepatocellular carcinoma patients treated by surgery or transarterial chemoembolization.

BACKGROUND AND AIMS: Hepatocellular carcinoma (HCC) prognostic scores could be useful in addition to the Barcelona Clinic Liver Cancer (BCLC) system to clarify patient prognosis and guide treatment decision. The NIACE (tumor Nodularity, Infiltrative nature of the tumor, serum Alpha-fetoprotein level, Child-Pugh stage, ECOG performance status) score distinguishes different prognosis groups among BCLC A, B, and C HCC patients. Our aims are to evaluate the NIACE score and its additive value in two HCC cohorts treated either by surgery or by chemoembolization, and then according to the BCLC recommendations. PATIENTS AND METHODS: This was a retrospective multicenter study with two BCLC A, B, and C HCC cohorts treated either by surgery (n=207) or by chemoembolization (n=168) carried out between 2008 and 2013. We studied survival time according to the baseline NIACE score and compared it with the Cancer of the Liver Italian Program score and the BCLC system. RESULTS: The NIACE score differentiates between subgroups of patients with different prognosis within each BCLC class. Among BCLC A patients treated by surgery and BCLC B patients treated by chemoembolization, the NIACE score differentiates between two subgroups with a significant difference in survival time: 68 (55-81) months versus 35 (21-56) months (P=0.0004) and 20 (17-24) months versus 13 (7-17) months (P=0.0008), respectively. Among those subgroups, the NIACE score has a significantly better prognostic value than the BCLC system or the Cancer of the Liver Italian Program score. CONCLUSION: In this study, among HCC patients treated according to the BCLC recommendations, the NIACE score predicts more accurately than any other system the survival time.

Prognosis of advanced hepatocellular carcinoma: a new stratification of Barcelona Clinic Liver Cancer stage C: results from a French multicenter study.

BACKGROUND: Advanced hepatocellular carcinoma (HCC) includes a wide spectrum of tumors and patients' prognosis after treatment is highly variable. Moreover, therapeutic options based on the Barcelona Clinic Liver Cancer (BCLC) staging system algorithm are restricted to one systemic therapy. AIM OF THE STUDY: To refine the stratification among BCLC C HCC patients by establishing a new simple prognostic score. PATIENTS AND METHODS: A regression model based on a BCLC stage C population and validated with an external cohort of BCLC C HCC patients defined the score. It was therefore validated among three external cohorts of BCLC C HCC patients treated with sorafenib. RESULTS: Five variables had independent prognostic values: the number of nodules, the infiltrating nature of the HCC, α-fetoprotein serum level, Child-Pugh score, and Eastern Cooperative Oncology Group Performance Status grade. They were integrated into a new score named NIACE ranging from 0 to 7, well correlated with survival. With the use of one threshold value, this score enables defining of two populations with different survivals among BCLC C patients and specifically among those treated with sorafenib. CONCLUSION: The NIACE score defines different prognostic subgroups after palliative treatment of HCC. It could be an additional tool for BCLC C HCC before inclusion in clinical trials or for the management of patients. These results must be validated in a prospective study.

Prognostic value of preoperative coronary computed tomography angiography in patients treated by orthotopic liver transplantation.

OBJECTIVES: The aim of this study was to assess the feasibility of 64-slice coronary computed tomography (CT) angiography in patients treated by orthotopic liver transplantation, and to compare prognostic values of CT angiography and dobutamine stress echocardiography in the same population. METHODS: Eighty-two consecutive patients, without known coronary artery disease, who underwent orthotopic liver transplantation, were included in this study. A CT angiography was performed along with usual explorations including dobutamine stress echography. A one-year minimal follow-up was performed to seek cardiac events. RESULTS: Fifty-two (65.8%) patients underwent a CT angiography. Thirty-seven (71%) were totally normal or showed nonobstructive coronary plaque, six (12%) showed at least one obstructive coronary plaque greater than 50%. Nine (17%) of the examined patients had at least one nonassessable segment. A total of six (7.6%) major cardiac events occurred in a mean-time follow-up of 17.8 ± 12.7 months. CONCLUSION: CT angiography that is normal or with a nonobstructive coronary plaque has a negative predicting value of 95% [0.82-0.99] for major cardiac adverse events, and of 100% [0.91-1] for clinical coronary events in patients undergoing orthotopic liver transplantation. The prognostic value of CT angiography was comparable with that of dobutamine stress echography.

Vena cava filter migration: an unappreciated complication. About four cases and review of the literature.

Inferior vena cava filter placement is performed to prevent pulmonary risk secondary to deep venous thrombosis. Indications for this treatment are limited to patients experiencing recurrences under well-managed anticoagulant treatment or presenting with contraindication to anticoagulant treatment. Nowadays, as these clinical situations are rare, this device is less and less used, all the more since, for several years now, thrombosis, fracture, or infectious complications as well as filter migration have been reported. Filter migrations are responsible for atypical and varied clinical presentations likely to defer diagnosis. To treat them, the filter is extracted, which is very risky in patients with a thromboembolic history. In our center, during a period of 14 years, we retrospectively collected and studied partial or complete vena cava filter migration cases that had been treated by extraction. We are reporting four very different clinical cases and, more specifically, the second published case of migration to a renal vein, which mimicked a systemic disease. Because of its very atypical clinical presentations, cava filter migration is an unappreciated and certainly underdiagnosed complication. However, this complication must not question cava filter placement when it is justified. In contrast, it prompts early filter extraction or long-term radiological surveillance.

Adrenal venous sampling is crucial before an adrenalectomy whatever the adrenal-nodule size on computed tomography.

OBJECTIVE: To assess the additional value of adrenal venous sampling (AVS) to diagnose primary aldosteronism sub-types in patients who have a unilateral nodule detected by computed tomography (CT scan) and who should undergo an adrenalectomy. METHODS: A retrospective study to assess consecutive patients with primary aldosteronism undergoing an adrenal CT scan and AVS. Criterion for selective cannulation was an equal or higher cortisol level in the adrenal vein compared to the inferior vena cava. An adrenal-vein aldosterone-to-cortisol ratio of at least two times higher than the other side defined lateralization of aldosterone production. RESULTS: Sixty-seven patients (mean age 52 years, 39 men) underwent a CT scan and AVS. In nine patients (13%), cannulation of the right adrenal vein led to a technical failure. Both procedures led to diagnosis of 29 patients with adenoma-producing aldosterone (APA; 50%), 23 bilateral adrenal hyperplasias (40%), and six unilateral adrenal hyperplasias (10%). Of the 45 patients with a nodule detected by CT, subsequent AVS showed bilateral secretion in 16 patients (36%). Compared to the strategy of coupling CT scans with AVS to diagnosis APA, a CT scan alone had an accuracy of 72.4% (P < 0.001). Among patients with a macronodule detected by CT, 13 (37%) had bilateral secretion as assessed by AVS. The patients with a macronodule detected by CT alone had the same risk of a discrepancy as those with a small nodule (P = 0.99). CONCLUSION: AVS is essential to diagnose the unilateral hypersecretion of aldosterone, even in patients in whom a unilateral macronodule is detected by CT, to avoid unnecessary surgery.

Congenital anomalies of inferior vena cava in young patients with iliac deep venous thrombosis.

Venous thromboembolism (VTE) in young patients is frequently associated with hereditary biological thrombophilia, autoimmune disorders, or neoplasia. Advances in venous ultrasound and contrast-enhanced computed tomography have allowed for the identification of inferior vena cava (IVC) anomalies as newly considered etiologic factor. We present two cases of VTE in young patients: the first case involves left IVC in a 22-year-old man and the second involves IVC atresia in a 39-year-old man. IVC anomalies should be identified in young patients with spontaneous VTE involving the iliac veins because they are at a high risk for thrombotic recurrence and adaptation to long periods of antithrombotic therapy.
