Chapter 996 [996] The Meaning of Communication

Professor Hao wore glasses, a suit and tie, and was very elegant, with an amiable face.

Two assistants next to him brought a computer to help screen the ppt content of the lecture.

"Dear colleagues, the special lecture I will bring to you today is some latest research progress on PTCD intraductal radiotherapy. This is a technology imported from abroad. It has been developed in our country for nearly ten years. It is not regarded as a domestic application. It is a very extensive but relatively mature technology. Now the technology used in our country is basically that iridium 192 wire enters the bile duct as the line source. As for the location of the placement and the distance from the tumor, these need more detailed research. Our hospital is This technology has been developed for more than eight years, and I have some experience to share with my colleagues.”

Even though he is a professor, he has a very modest attitude when discussing academic issues, and he is full of bookishness in his steady speech.

The audience is basically silent, and everyone is studying quietly.

"The sensitivity of cholangiocarcinoma to chemotherapy is actually not high. This technology was not firstly applied to cholangiocarcinoma. However, after being used in clinical practice, there are many gratifying discoveries. For example, if the tumor is less than 1.5 cm, it can only be treated with intracavitary chemotherapy." Irradiation can prolong the survival period. For tumors larger than 1.5 cm, it is best to add extracavitary irradiation, which is definitely much better than pure extracavitary irradiation. The survival period of patients can also be relatively prolonged.”

Probably because he felt that the meeting room was a bit boring while talking. Professor Hao adjusted the atmosphere and said to the audience: "If you have any ideas or suggestions from colleagues, you can ask questions and speak at any time. We can see it by raising your hand."

Hearing what he said, someone raised their hand.

The assistant immediately handed over the microphone to this person.

"Excuse me, Dr. Hao, is this technology only used in palliative care? Our hospital once wanted to try to apply it before and after surgery. I don't know if your hospital has tried practice and research in this area. I want to know how to shrink tumors before surgery. And is it meaningful to remove the residual tumor tissue after surgery? We have read relevant papers, and some colleagues have done similar research, but there are few cases for some reason. Can I ask Professor Hao to answer related questions? "

The doctor who asked the question asked a series of questions, all of which were practical questions full of dry goods, which showed that he was definitely a first-line doctor.

Professor Hao smiled, asked the other party to sit down, and explained: "About the questions you mentioned, especially the last one, why is this kind of preoperative and postoperative application less common? The main reason is that we shrink tumors before surgery and This is not the only technique for removing residual tumor tissue. Compared with other techniques, as I said at the beginning, cholangiocarcinoma is less sensitive to radiotherapy. With advanced chemotherapy drugs, we can certainly use chemotherapy drugs to shrink tumors And remove the residual tumor tissue. This technology can only be said to have certain advantages in palliative therapy, because it can locally destroy the tumor. If there are more advanced drugs in the future, there will be no need for stents to maintain drainage.”

After the expert finished speaking, the frontline doctors at the grassroots level were inspired and got up to say thanks again.

The lecture continues. Dose issues, irradiation distance issues, and various research tables are listed on the ppt. The audience in the audience took notes while watching some of them. Although this technique is not considered surgery, adjuvant therapy is just as crucial to surgery. When some patients really cannot undergo surgery, it is really necessary for the doctor to find a way.
