Percy... let me respectfully disagree with your criticism of this study.
it seems to me that the study is more concern about the damage of the bile ducts by RFA than the more positive results that RFA can provide to intrahepatic CCA patients like me.
That was the explicit goal of the study. The benefits of RFA are well known. The data about injuries is limited. They wrote: "This study aimed to assess the incidence, prognosis and risk factors of intrahepatic biliary injury associated with radiofrequency ablation."
Dose the study mean that bile duct cancer patient, like me, should not have RFA procedure because it will damage our bile ducts in the liver?
No, the study doesn't say anything like that. Their conclusion was: "The incidence of biliary injury was not frequent (1.8%). Through appropriate treatment, intrahepatic bile duct injuries seemed not affect the patients' long-term survival."
As a patient, how can you give an INFORMED consent if you don't know the risks and their incidence rate?
Before we signed the consent to do Whipple, the surgeon told us the % of patients who develop pancreatic leaks. Before we signed the consent to do 3D radiation, the radiation ONC cited the incidence rates of spinal injuries and compromised surgical connections. The numbers came out of studies similar to this one.
Really, I don't see anything controversial about this study.
