A three-stage genome-wide association study identifies a susceptibility locus for late radiotherapy toxicity at 2q24.1

There is increasing evidence supporting the role of genetic variants in the development of radiation-induced toxicity(1). However, previous candidate gene association studies failed to elucidate the common genetic variation underlying this phenotype(2), which could emerge years after the completion of treatment(3). We performed a genome-wide association study on a Spanish cohort of 741 individuals with prostate cancer treated with external beam radiotherapy (EBRT). The replication cohorts consisted of 633 cases from the UK4 and 368 cases from North Americas. One locus comprising TANC1 (lowest unadjusted P value for overall late toxicity = 6.85 x 10(-9), odds ratio (OR) = 6.61, 95% confidence interval (CI) = 2.23-19.63) was replicated in the second stage (lowest unadjusted P value for overall late toxicity = 2.08 x 10(-4), OR = 6.17,95% CI = 2.25-16.95; P-combined = 4.16 x 10(-10)). The inclusion of the third cohort gave unadjusted P-combined = 4.64 x 10(-11). These results, together with the role of TANC1 in regenerating damaged muscle, suggest that the TANC1 locus influences the development of late radiation-induced damage

The histology of brain tumors for 67 331 children and 671 085 adults diagnosed in 60 countries during 2000-2014: a global, population-based study (CONCORD-3)

Auteurs : The CONCORD Working GroupInternational audienceBackground: Global variations in survival for brain tumors are very wide when all histological types are considered together. Appraisal of international differences should be informed by the distribution of histology, but little is known beyond Europe and North America.Methods: The source for the analysis was the CONCORD database, a program of global surveillance of cancer survival trends, which includes the tumor records of individual patients from more than 300 population-based cancer registries. We considered all patients aged 0-99 years who were diagnosed with a primary brain tumor during 2000-2014, whether malignant or nonmalignant. We presented the histology distribution of these tumors, for patients diagnosed during 2000-2004, 2005-2009, and 2010-2014.Results: Records were submitted from 60 countries on 5 continents, 67 331 for children and 671 085 for adults. After exclusion of irrelevant morphology codes, the final study population comprised 60 783 children and 602 112 adults. Only 59 of 60 countries covered in CONCORD-3 were included because none of the Mexican records were eligible. We defined 12 histology groups for children, and 11 for adults. In children (0-14 years), the proportion of low-grade astrocytomas ranged between 6% and 50%. Medulloblastoma was the most common subtype in countries where low-grade astrocytoma was less commonly reported. In adults (15-99 years), the proportion of glioblastomas varied between 9% and 69%. International comparisons were made difficult by wide differences in the proportion of tumors with unspecified histology, which accounted for up to 52% of diagnoses in children and up to 65% in adults.Conclusions: To our knowledge, this is the first account of the global histology distribution of brain tumors, in children and adults. Our findings provide insights into the practices and the quality of cancer registration worldwide

Primer consenso interinstitucional de neoplasias mieloproliferativas crónicas

Objetivo: El objetivo del consenso es poner a disposición de los profesionales de las diferentes instituciones de salud pública en nuestro país, quienes se encuentran a cargo de estas enfermedades, la información más relevante y actualizada acerca de su diagnóstico y tratamiento en la práctica clínica. Con este consenso interinstitucional esperamos contribuir a mejorar la calidad de la atención de los pacientes con neoplasias mieloproliferativas crónicas a todo lo ancho y largo de la República Mexicana, con el fin de unificar criterios tanto en diagnóstico como en tratamiento de las diferentes enfermedades mieloproliferativas
