Precision medicine focuses on DNA abnormalities, but not all tumors have tractable genomic alterations. The WINTHER trial (NCT01856296) navigated patients to therapy on the basis of fresh biopsy-derived DNA sequencing (arm A; 236 gene panel) or RNA expression (arm B; comparing tumor to normal). The clinical management committee (investigators from five countries) recommended therapies, prioritizing genomic matches; physicians determined the therapy given. Matching scores were calculated post-hoc for each patient, according to drugs received: for DNA, the number of alterations matched divided by the total alteration number; for RNA, expression-matched drug ranks. Overall, 303 patients consented; 107 (35%; 69 in arm A and 38 in arm B) were evaluable for therapy. The median number of previous therapies was three. The most common diagnoses were colon, head and neck, and lung cancers. Among the 107 patients, the rate of stable disease ≥6 months and partial or complete response was 26.2% (arm A: 23.2%; arm B: 31.6% (P = 0.37)). The patient proportion with WINTHER versus previous therapy progression-free survival ratio of >1.5 was 22.4%, which did not meet the pre-specified primary end point. Fewer previous therapies, better performance status and higher matching score correlated with longer progression-free survival (all P < 0.05, multivariate). Our study shows that genomic and transcriptomic profiling are both useful for improving therapy recommendations and patient outcome, and expands personalized cancer treatment.

The availability of the data is described in the Nature Research Reporting Summary. Detailed clinical and biological information for each patient is available in Supplementary Table 4; further biological data are available at www.winconsortium.org, containing: (1) tumor mutations data in XML format; and (2) expression data in a table format (providing information about tumor versus normal fold change and tumor intensity alone for all of the cases for which mRNA was analyzed). The BAM and XML files for normal tissue are deposited in dbGaP with a controlled access mechanism for private information.
No custom code or mathematical algorithm was used. Statistical analysis was performed using standard software including SAS and R.

Extended Data Fig. 6 Effect of individual variability of normal VEGFA RNA expression on the assessment of VEGFA levels in tumors.
On the y axis, the transcript intensity in tumors is shown, and on the x axis the transcript intensity in matched normal biopsies is shown. Intensities are measured as a relative fluorescence unit (RFU) signal as assessed with Agilent microarray technology. Overexpression in the tumor is denoted in turquoise points, underexpression is denoted in red and no change is denoted in black. The twofold threshold (both high and low) is indicated by two dotted black lines. All 101 patients of the WINTHER study with evaluable RNA data were considered. Example 1 shows a patient with a low level of basal expression (300 RFU) in the tumor and 300 RFU in the normal biopsies, with no differential expression between the normal and tumor biopsies. Example 2 shows a patient with a high level of basal expression of 6,000 RFU in the tumor versus 6,000 RFU in the normal biopsies, but again no differential expression between the tumor and normal counterpart. Example 3 marked in turquoise shows the pattern of a higher expression in tumor versus normal tissue. Example 4 marked in red shows the pattern of a lower expression in tumor versus normal tissue. This current study hypothesizes that simultaneously investigating the matched phenotypically normal tissue can help to optimize transcriptomic data. With this approach, each patient serves as his or her own control, hence avoiding the use of pooled tumor or normal tissues. Our data demonstrate that the level of basal gene expression is highly variable between individuals. All patients presented with black points had no differential expression between tumor and normal tissue, but others show a large variability between individuals in the basal level of normal expression of VEGFA.
