Decrement of the thenar compound muscle action potentials (CMAP), after repetitive nerve stimulation (RNS) of the median nerve at 3 Hz, was evaluated in patients with ALS before riluzole therapy. CMAP size as well as motor unit number and size estimates were evaluated twice before and after 1 year of riluzole therapy. The correlation between decrement and CMAP size reduction per year was highly significant (r = 0.77), but no relationship could be demonstrated between decrement and other variables. The authors thus propose that decrement after RNS may be used as a predictor of further drop in CMAP size. [less ▲]Detailed reference viewed: 10 (0 ULg)

AIM : FDG uptake has been shown to predict the outcome in large series of patients with hepatocarcinoma (HCC) in Asia, but few data are available regarding European populations. Our aim was to evaluate the prognostic value of pretreatment FDG PET-CT in patients treated by liver transplantation. Methods: We retrospectively analyzed the data of 27 patients (24 M and 3 W, mean age 58 ± 9 years). The mean follow-up was 26 ± 18 months (min 1 month, max 66 months). All patients had an FDG PET-CT before the transplantation. The FDG PET/CT was performed according to a standard clinical protocol: 4 MBqFDG/kg body weight, uptake 60 min., low-dose non-enhanced CT. We measured the SUVmax and SUVmean of the tumor and the normal liver. The tumor/liver activity ratios (RSUVmax and RSUVmean) were tested as prognostic factors and compared to the following conventional prognostic factors: MILAN, CLIP, OKUDA, TNM stage, alphafoetoprotein level, portal thrombosis, size of the largest nodule, tumor differentiation, microvascular invasion, underlying cirrhosis and liver function. Results : The DFS was 87.2% at 1y and 72.1% at 3y. The OS was 85.2% at 1y and 80.7% at 3y. According to an univariate Cox model, RSUVmax, RSUVmean and healthy liver were predictors of DFS and RSUVmax, RSUVmean, size of the largest nodule, CLIP, liver involvement>50%, and healthy liver predicted the OS. According to a multivariate Cox model, only RSUVmax predicted DFS and RSUVmax and liver involvement>50% predicted OS. An ROC analysis of the ratios showed that the 1.15 cut-off for RSUVmax was best for predicting both the DFS (Cox regression:HR 14.4, p=0.02) and OS (HR 5.6, p=0.049). The Kaplan-Meier curves and Logrank tests confirmed those results. Even though the MILAN criteria alone were not predictive, it is worth noting that none of the patients outside the MILAN criteria and with RSUVmax<1.15 relapsed. Conclusions: The RSUVmax is a strong prognostic factor for recurrence and death in patients with HCC treated by liver transplantation with a cut-off value of 1,15. further prospective studies should test whether the metabolic index should be systematically included in the preoperative assessment.

INTRODUCTION: The aim of this multicenter, prospective study was to evaluate the long-term prognostic value of low-dose dobutamine stress echocardiography (LDDSE) in patients with aortic stenosis (AS) and depressed left ventricular (LV) function. MATERIAL AND METHODS: The study group comprised 39 patients (34 male, mean age 59 +/-13 years) with AS (peak gradient > 25 mm Hg), LV ejection fraction (LVEF) </= 45% and low transaortic gradient (peak gradient </= 45 mm Hg, mean gradient </= 35 mm Hg). The qualification for subsequent therapeutic procedures was based on generally accepted indications. All patients underwent LDDSE and coronary angiography. Twelve months after LDDSE patients underwent control resting echocardiography and clinical evaluation. RESULTS: Twenty-seven (69.2%) patients had preserved contractile reserve. In this subgroup, true-severe AS was diagnosed in 12 patients, whereas pseudo-severe AS was found in 15 patients. Nine patients with true-severe AS, 2 patients with pseudo-severe AS and 7 patients without contractile reserve were referred for surgical treatment. The independent risk factors of death during follow-up were: aortic valve area (AVA) at peak stress < 0.8 cm(2) (OR 1.4; p = 0.003) and LVEF at rest < 35% (OR 6.8; p = 0.05). The independent risk factors of composite end-point (death or myocardial infarctions or pulmonary edema) were: AVA at stress < 0.8 cm(2) (OR 4.0; p = 0.03), absence of AVA increase during LDDSE (OR 5.7; p = 0.005), absence of contractile reserve (OR 4.5; p = 0.01) and presence of significant CAD (OR 6.9; p = 0.02). CONCLUSIONS: In patients with AS and depressed LVEF, LDDSE is a useful tool for long-term risk stratification. [less ▲]Detailed reference viewed: 10 (1 ULg)

BACKGROUND: The intensity of the [F]fluorodeoxyglucose (F-FDG) uptake is an independent prognostic indicator in non-small cell lung cancer (NSCLC). We evaluate the relationship between the metabolic activity of the primary and the pleurisy in T4 NSCLC. METHODS: 25 patients (16 males, nine females, mean age 63 years, performance status 1) with pathology-proven, T4 NSCLC and malignant pleurisy were included. All were treated by a platinum salt-based chemotherapy regimen. Positron emission tomography (F-FDG-PET) was performed before treatment, according to a routine procedure. Regions of interest were placed over the primary and the pleural effusion on the transaxial slice showing the highest activity. The maximum pixel standard uptake values (SUVs) were calculated. Overall survival was determined by standard Kaplan-Meier survival analysis. All patients were followed up until death. RESULTS: The median survival for the entire population was 83 days (7-988). The SUVs were higher in the primary than in the pleurisy (9.2+/-5.6 and 5.5+/-2.2, respectively). There was no correlation between primary and pleurisy SUVs (r=0.3, P>0.05). The metabolic activity of the primary tumor did not predict the outcome: the median survival was 77.5 days (range 7-988) and 87 days (19-454) in the groups with SUVs lower and higher than the median value (8.7), respectively (P>0.05). By contrast, the metabolic activity of the pleurisy was significantly correlated with the median survival, which was 196 days (40-988) when the SUVs were lower than the median value (5) and 74 days (7-170) when they were higher (P=0.0096). CONCLUSION: Among patients with T4 NSCLC, those with high metabolic activity in the pleural effusion have a dire prognosis, whereas the metabolic activity of the primary fails to predict the survival.

PURPOSE: To investigate early prostate-specific antigen (PSA) kinetics after high radiation doses of 85 Gy on locally advanced prostate cancer. METHODS AND MATERIALS: A total of 201 patients were prospectively and consecutively treated with external beam radiotherapy and a brachytherapy boost. Of the 201 patients, 104 received concomitant hormonal therapy on the decision of the referring urologist and were excluded, yielding a study population of 97 patients. The first posttreatment PSA analysis was performed not earlier than 1 month after treatment completion but within the first 4 months, and then every 4 months. Analysis of PSA kinetics included the PSA nadir (nPSA) at values of < or =4 ng/mL to < or =0.5 ng/mL. The nPSA at < or =4 ng/mL within 4 months (nPSA < or =4/4m) was the variable of interest. RESULTS: We established highly significant associations between an nPSA of < or =1 and < or =0.5 ng/mL and the nPSA < or =4/4m (p <0.0001). A hazard ratio of 0.33 (95% Confidence Interval (CI), 0.12-0.91) underlined the lower risk of recurrence related to nPSA < or =4/4m achievement (p = 0.033). Using time-dependent covariate models for patients who did not reach an nPSA < or =4/4m, an nPSA of < or =1 ng/mL remained without prognostic significance (p = 0.06). However, for patients who reached an nPSA < or =4/4m, an nPSA of < or =1 ng/mL did significantly improve the prognosis (p <0.001), but much later after treatment. The same analysis was repeated for nPSA < or =0.5 ng/mL with similar conclusions as when nPSA < or =4/4m was obtained (p <0.01). CONCLUSION: The nPSA < or =4/4m has been demonstrated to be a significant predictor of biochemical no evidence of disease after high radiation doses of 85 Gy. Its major advantage is that it was available earlier than the other nadirs. [less ▲]Detailed reference viewed: 100 (3 ULg)

Vascular renal resistance (RR) during hypothermic machine perfusion (HMP) is frequently used in kidney graft quality assessment. However, the association between RR and outcome has never been prospectively validated. Prospectively collected RR values of 302 machine-perfused deceased donor kidneys of all types (standard and extended criteria donor kidneys and kidneys donated after cardiac death), transplanted without prior knowledge of these RR values, were studied. In this cohort, we determined the association between RR and delayed graft function (DGF) and 1-year graft survival. The RR (mmHg/mL/min) at the end of HMP was an independent risk factor for DGF (odds ratio 21.12 [1.03–435.0]; p = 0.048) but the predictive value of RR was low, reflected by a c-statistic of the receiver operator characteristic curve of 0.58. The RR was also found to be an independent risk factor for 1-year graft failure (hazard ratio 12.33 [1.11–136.85]; p = 0.004). Determinants of transplant outcome are multifactorial in nature and this study identifies RR as an additional parameter to take into account when evaluating graft quality and estimating the likelihood of successful outcome. However, RR as a stand-alone quality assessment tool cannot be used to predict outcome with sufficient precision. [less ▲]Detailed reference viewed: 24 (2 ULg)

The prognostic value of stress electrocardiogram and thallium-201 stress myocardial scintigraphy was analyzed in 224 patients 3 months after a myocardial infarction; both techniques allowed an adequate stratification based on the presence of ST depression or multivessel disease. Combining stress electrocardiogram and stress myocardial scintigraphy data improved the prognostic ability, particularly in patients who associated multivessel disease and ST depression.
