TY - JOUR T1 - BRca1 and brca2 mutations in ovarian cancer AU - Buerkle B, Tempfer C Y1 - 2012/01/25 N1 - 10.1001/jama.2012.8 JO - JAMA SP - 359 EP - 361 VL - 307 IS - 4 N2 - To the Editor: Dr Yang and colleagues found significantly better progression-free survival rates in women with ovarian cancer and BRCA2 mutations compared with BRCA1 mutations or wild-type BRCA.1 In addition, they reported that BRCA2 mutations were associated with a 100% primary chemotherapy sensitivity rate compared with 82% for BRCA wild-type and 80% for BRCA1- mutated cases, suggesting an improved primary chemotherapy response in women with a BRCA2 mutation. We would like to suggest 2 alternative explanations for the observed differences in outcomes. SN - 0098-7484 M3 - doi: 10.1001/jama.2012.8 UR - http://dx.doi.org/10.1001/jama.2012.8 ER -
