Professor Hao wears glasses, a suit and tie, is very elegant, and has an amiable face.
Two assistants brought computers over to help show the ppt content of the lecture.
"Dear colleagues, the special lecture I bring to you today is about some of the latest research progress on intrabiliary radiotherapy for PTCD. This is a technology introduced from abroad. It has been developed in our country for almost ten years. It is not considered to be applied domestically.
It is a very widespread but relatively mature technology. The technology currently used in our country is basically to insert iridium 192 wire into the bile duct as a wire source. As for the placement position and the distance from the tumor, these require more detailed research. Our hospital is
I have been working on this technology for more than eight years, and I would like to share my experience with my peers.”
Even though he is a professor, he is very humble when discussing academic issues, and his words are steady and full of scholarly spirit.
There was almost no sound in the audience, everyone was studying quietly.
"The sensitivity of cholangiocarcinoma to chemotherapy is actually not high. This technology was not first applied to cholangiocarcinoma. However, after being used in clinical practice, there are many gratifying findings. For example, if the tumor is less than 1.5 cm, only intraluminal
With irradiation, the survival period can be prolonged. For tumors larger than 1.5 cm, it is best to add extracavitary irradiation, which is definitely better than simple extracavitary irradiation anyway. The patient's survival period can also be relatively prolonged."
Probably because he felt that the conference room was a little boring while he was 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 you by raising your hand."
Hearing him say this, someone raised their hands.
The assistant immediately handed the microphone to this person.
"I would like to ask Dr. Hao, is this technology only used in palliative care? Our hospital once wanted to try to apply it in preoperative and postoperative aspects. I don't know if your hospital has tried practice and research in this area. I would like to know whether it can reduce tumors before surgery.
And is it meaningful to remove residual tumor tissue after surgery? We have read relevant papers and some colleagues have done similar research, but for some reason there are very few cases. Can Professor Hao answer relevant questions?"
The doctor who asked this question asked a series of questions, all of which were practical questions full of useful information, indicating that he is definitely a front-line doctor.
Professor Hao smiled, asked the other party to sit down, and explained: "As for the questions you mentioned, especially the last question, why is this type of surgery less commonly used before and after surgery? The main reason is that we shrink the tumor before surgery and reduce the risk of surgery.
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 of course use chemotherapy drugs to shrink tumors.
And remove residual tumor tissue. This technology can only be said to have certain advantages in palliative care, as it can locally eliminate tumors. If more advanced drugs are available in the future, stents will no longer be needed to maintain drainage."
After the experts finished speaking, the front-line doctors at the grassroots level were inspired and stood up to say thank you again.
The lecture continued. Dosage issues, irradiation distance issues, and various research tables were listed on ppt. Some of the audience in the audience took pens to take notes while watching. Although this technology is not considered surgery, auxiliary therapy is equally important for surgery.
It's important. When some patients really can't undergo surgery, they really need the doctor to find another way.
