Hospital Radiology: The diagnosis of cholangiocarcinoma should be clear, because the imaging manifestations with other tumor indicators (glycoantigens) elevated as you mentioned can support this diagnosis. Hepatocellular carcinoma can be distinguished under microscope, and beam-like arrangement can be seen for moderately differentiated degree. According to the condition, gemcitabine (1000mg) and oxaliplatin (150mg) can be used for interventional treatment, in which 50mg of oxaliplatin powder is mixed with 10ml of super-liquidated iodine oil and then embolized, and the rest of drugs are dissolved and slowly (!!!) injected. injection, the injection of gemcitabine is more painful, it is advisable to dilute and inject slowly, and if necessary, dilute lidocaine can be injected via catheter. Overall, doxorubicin is not an indication for cholangiocarcinoma, and the blood supply of the tumor seen in CT is not very rich, so that the effect is estimated to be limited, but if we look at its mechanism of action, it will all be somewhat effective in theory. However, it is not scientific to say that the side effects are effective or that the side effects are good!
