Raw images are provided on the right panel. a Tumor evaluation at the stage of the initial CCA diagnosis (October 2015, was done with liver vein contrasting (7.5 ml Gadovist). Sum of diameters of target lesions equals 221 mm; b tumor progression after the best clinical practice care (July 2016). Sum of diameters of target lesions equals 278 mm (26% increase); c tumor growth during Sorafenib treatment (October 2016). Sum of diameters of target lesions equals 314 mm (16% increase); d tumor growth after Sorafenib treatment prior to start of Pazopanib (January 2017). Sum of diameters of target lesions equals 392 mm (35.3% increase). e Tumor progression after Pazopanib treatment (July 2017).
