RESUMO

Background: Concomitant chemotherapy (CT)-radiotherapy (RT) is a standard of care in locally advanced nasopharyngeal carcinoma (NPC) and a role for induction CT is not established. Methods: Patients with locally advanced NPC, WHO type 2 or 3, were randomized to induction TPF plus concomitant cisplatin-RT or concomitant cisplatin-RT alone. The TPF regimen consisted of three cycles of Docetaxel 75 mg/m2 day 1; cisplatin 75 mg/m2 day 1; 5FU 750 mg/m2/day days 1-5. RT consisted of 70 Gy in 7 weeks plus concomitant cisplatin 40 mg/m2 weekly. Results: A total of 83 patients were included in the study. Demographics and tumour characteristics were well balanced between both arms. Most of the patients (95%) in the TPF arm received three cycles of induction CT. The rate of grade 3-4 toxicity and the compliance (NCI-CTCAE v3) during cisplatin-RT were not different between both arms. With a median follow-up of 43.1 months, the 3-year PFS rate was 73.9% in the TPF arm versus 57.2% in the reference arm [hazard ratio (HR) = 0.44; 95% confidence interval (CI): 0.20-0.97, P = 0.042]. Similarly the 3 years overall survival rate was 86.3% in the TPF arm versus 68.9% in the reference arm (HR = 0.40; 95% CI: 0.15-1.04, P = 0.05). Conclusion: In conclusion, several important aspects can be emphasized: the compliance to induction TPF was good and TPF did not compromise the tolerance of the concomitant RT-cisplatin phase. The improved PFS and overall survival rates needs to be confirmed by further trials.

RESUMO

BACKGROUND: Few studies have evaluated abnormalities on brain magnetic resonance imaging (MRI) in children and adolescents with chronic liver disease. AIMS: The aim of this study was to investigate the presence of T1 hyperintensity in the basal ganglia of pediatric patients with portal hypertension and its association with blood manganese levels. METHODS: A case control study of 22 patients with portal hypertension (14 Child-Pugh A cirrhosis, 8 non-cirrhotic portal hypertension) and 15 controls was conducted from 2006 to 2007. Blood manganese levels were measured using atomic absorption spectrophotometry. Brain MRI scans were performed using a 1.5 Tesla (Philips) scanner. RESULTS: Blood manganese levels were 26.01+/-12.82 microg/L for patients with portal hypertension (cirrhotic: 22.73+/-11.67 microg/L, non-cirrhotic: 32+/-13.32 microg/L) and 15.64+/-6.61 microg/L for controls (p=0.003). 14/22 patients with portal hypertension presented T1 hyperintensity in the basal ganglia [6/14 cirrhotic; 8/8 non-cirrhotic (p=0.018); zero controls (p=0.001)]. Mean blood manganese levels of patients with liver disease and normal vs. abnormal brain MRI scans were 18.45+/-8.38 microg/L and 30.47+/-13.07 microg/L, respectively (p=0.04). CONCLUSIONS: Brain MRI showed a high frequency (64%) of T1 hyperintensity in the basal ganglia of patients with portal hypertension, which correlated positively with blood manganese levels. This abnormality was found in 100% of the patients with portal hypertension and in 43% of those with mild cirrhotic disease.

RESUMO

Head and neck cancers are the fifth among the most common cancers in France. Two thirds of cases occur at an advanced stage. For advanced disease, progression-free survival, despite undeniable progress, remains below 50% at three years. The last 20 years have been marked by the necessity to identify situations where less intense surgery and/or radiotherapy and/or chemotherapy is possible without jeopardizing the prognosis, and situations where a therapeutic intensification is necessary and results in a gain in survival while better preserving function with less toxicity. French cooperative groups gathering radiation oncologists (GORTEC), surgeons (GETTEC) and medical oncologists or physicians involved in the management of systemic treatments in head and neck cancers (GERCOR) are now belonging to the INCa-labelled Intergroup ORL to deal with the challenges of head and neck cancers.

RESUMO

A simple spot test for the detection of PAS in urine has been described and its sensitivity compared with that of other methods such as the Ehrlich's reagent and the ferric chloride tests. In patients receiving 4 g. PAS the three methods gave similar results in urine specimens collected within eight hours. The new test is an inexpensive micro method which can easily be performed on a large scale. There is no reaction with sulfonamide or salicylic acid derivatives.
