Results from a prospective sero-epidemiological study initiated in Uganda in 1971 indicate that children with high antibody titres to Epstein-Barr virus structural antigens are at high risk of developing Burkitt's lymphoma. These findings strongly support a causal relationship between the Epstein-Barr virus and Burkitt's lymphoma but suggest that the oncogenic potential of the virus is realised only in exceptional circumstances.

Background:Transarterial chemoembolisation (TACE) has not been shown to be superior to bland embolisation (TAE) for treatment of hepatocellular carcinoma (HCC).Methods:We conducted a randomised phase II/III trial in patients with untreated HCC. Patients were randomised to TAE with polyvinyl alcohol (PVA) particles alone or sequential TACE (sTACE) in which cisplatin 50 mg was administered intrarterially 4–6 h before PVA embolisation. Treatment was repeated 3-weekly for up to three treatments. The primary endpoint was overall survival and secondary endpoints were progression-free survival, toxicity and response. Target sample sizes for phase II and III were 80 and 322.Results:The trial was terminated at phase II after 86 patients had been randomised. Patients were well matched for prognostic criteria. All three planned treatments were given to 57.1% (TAE) and 56.8% (TACE) patients. Grade 3/4 toxicity occurred in 63.5% and 83.7%, respectively (P=0.019). End-of-treatment RECIST response (CR+PR) was 13.2 and 32.6% (P=0.04) (mRECIST 47.3% and 67.4) and median overall survival and progression-free survival was 17.3 vs 16.3 (P=0.74) months and 7.2 vs 7.5 (P=0.59), respectively.Conclusion:Transarterial chemoembolisation according this novel schedule is feasible and associated with a higher response rate than TAE alone. The survival benefit of TACE over TAE remains unproven.

PurposeThe glomerular filtration rate (GFR) is essential for carboplatin chemotherapy dosing; however, the best method to estimate GFR in patients with cancer is unknown. We identify the most accurate and least biased method.MethodsWe obtained data on age, sex, height, weight, serum creatinine concentrations, and results for GFR from chromium-51 (51Cr) EDTA excretion measurements (51Cr-EDTA GFR) from white patients ≥ 18 years of age with histologically confirmed cancer diagnoses at the Cambridge University Hospital NHS Trust, United Kingdom. We developed a new multivariable linear model for GFR using statistical regression analysis. 51Cr-EDTA GFR was compared with the estimated GFR (eGFR) from seven published models and our new model, using the statistics root-mean-squared-error (RMSE) and median residual and on an internal and external validation data set. We performed a comparison of carboplatin dosing accuracy on the basis of an absolute percentage error > 20%.ResultsBetween August 2006 and January 2013, data from 2,471 patients were obtained. The new model improved the eGFR accuracy (RMSE, 15.00 mL/min; 95% CI, 14.12 to 16.00 mL/min) compared with all published models. Body surface area (BSA)–adjusted chronic kidney disease epidemiology (CKD-EPI) was the most accurate published model for eGFR (RMSE, 16.30 mL/min; 95% CI, 15.34 to 17.38 mL/min) for the internal validation set. Importantly, the new model reduced the fraction of patients with a carboplatin dose absolute percentage error > 20% to 14.17% in contrast to 18.62% for the BSA-adjusted CKD-EPI and 25.51% for the Cockcroft-Gault formula. The results were externally validated.ConclusionIn a large data set from patients with cancer, BSA-adjusted CKD-EPI is the most accurate published model to predict GFR. The new model improves this estimation and may present a new standard of care.
