Additional file 4: Table S3. of Next generation sequencing of triple negative breast cancer to find predictors for chemotherapy response
List of all mutations. This file shows all mutations passing thresholds as explained in “Methods”. The column “confirmed” shows mutations that have been confirmed by either Sanger Sequencing or deep whole exome sequencing in another research project (unpublished data). The column “included in analysis” shows the mutations that passed our threshold for putative driver mutations, based on effect, SIFT, polyphen scores and COSMIC (see “Methods”). The column “dubious” shows the mutations that might be dubious based on gene length, expression or replication time [20]. (XLSX 64 kb
Additional file 9: Figure S3. of Next generation sequencing of triple negative breast cancer to find predictors for chemotherapy response
Validation of TTK, TP53BP2 and genome-wide copy number profiles with Nimblegen 135Ă‚Â K aCGH arrays. aCGH and exome data, for the samples for which aCGH data were available (three cases for TTK, five cases for TP53BP2). Arrow indicates respectively the TTK and TP53BP2 locus. From page 3 on we show all 14 samples for which we have both exome and aCGH data, irrespective of TTK and TP53BP2 status. In these rainbow plots, the samples containing a TTK or TP53BP2 gain are indicated with an arrow at the respective genomic location. (PDF 1639 kb

Evaluation of the <i>EGFR</i> polymorphism R497K in two cohorts of neoadjuvantly treated breast cancer patients
<div><p>Pathological response of breast cancer to neoadjuvant chemotherapy (NAC) presents great variability, and new prognostic biomarkers are needed. Our aim was to evaluate the association of the epidermal growth factor receptor gene (<i>EGFR</i>) polymorphism R497K (rs2227983) with prognostic features and clinical outcomes of breast cancer, including the pathological response to NAC and the recurrence-free survival (RFS). Tumoral complete response (tCR) was defined by no remaining invasive cancer in the excised breast, whereas pathological complete response (pCR) was defined by no remaining invasive cancer both in the excised breast and lymph nodes. Two independent cohorts were analyzed: one from Brazil (INCA, n = 288) and one from The Netherlands (NKI-AVL, n = 255). In the INCA cohort, the variant (Lys-containing) genotypes were significantly associated with lower proportion of tCR (OR<sub>adj</sub> = 0.92; 95%CI = 0.85–0.99), whereas in the NKI-AVL cohort they were associated with tumor grade 3 (p = 0.035) and with triple-negative subtype (p = 0.032), but not with clinical outcomes. Such distinct prognostic associations may have arisen due to different neoadjuvant protocols (p < 0.001), or to lower age at diagnosis (p < 0.001) and higher proportion of tumor grade 3 (p = 0.018) at the NKI-AVL cohort. Moreover, NKI-AVL patients achieved better proportion of pCR (21.2% <i>vs</i> 8.3%, p < 0.001) and better RFS (HR<sub>adj</sub> = 0.48; 95% <sub>adj</sub>CI = 0.26–0.86) than patients from INCA. In conclusion, large scale studies comprehending different populations are needed to evaluate the impact of genome variants on breast cancer outcomes.</p></div
