Optofluidic results for blood samples, and computerised tomography of cancer patients at the time of blood extraction. (A) 3 healthy donors and (B) 5 cancer patients. (C) Computerised tomography scans of the cancer patients at the time of blood extraction. CP1, lung metastasis (red arrow). CP2, bone scintigraphy and MRI before (showing a lytic metastasis in C6) and at the time of blood extraction (complete remission). CP3, recently diagnosed and untreated yet metastatic adenopathy (red arrow). CP4, vertebral osteoblastic metastasis showing the current bone progression of the disease (red arrow). CP5, malignant pleural effusion (red arrow) and mediastinal mass (blue arrow). At the time of the study, CP5 had received four cycles of specific treatment. (D) Comparison of the results for the blood samples between the flow-cytometry and the optofluidic device.
