In the conference room, doctors from the two hospitals were in intense discussions and negotiations.
Lung cancer is prone to brain metastasis.
Patients with brain metastasis from lung cancer are often seen in the Department of Thoracic Surgery at Guozhi and Guoxie Hospitals.
There are cases like Dean Liang where brain metastasis is confirmed and lung cancer is discovered later, but they are extremely rare.
Generally, these patients are in the late stage and it is due to the patients' own factors that they delayed going to the hospital for examination, which should be distinguished from the situation of President Liang.
The reasons why lung cancer is prone to brain metastasis can be roughly attributed to two reasons.
First, cancer needs to be pathologically classified, so a pathologist is present on site to participate.
The type of lung cancer most likely to metastasize to the brain is small cell carcinoma, a highly malignant form of the disease.
Second, due to the anatomical connection between the lungs and the brain, even cancer cells with a lower degree of malignancy are more likely to metastasize to the brain than cancer cells in other parts of the body.
...
...
To be specific, the blood vessels of the lungs have abundant anastomotic branches with the vertebral veins that supply the brain, and these anastomotic branches do not need to communicate with the pulmonary capillaries.
As mentioned in the previous article, the pulmonary circulation exchanges substances through the pulmonary capillaries, converting venous blood into arterial blood that enters the heart and is then pumped throughout the body.
However, due to the presence of these anastomotic branches that do not pass through the pulmonary capillaries, the cancer cells in the pulmonary blood vessels do not need to be filtered through the pulmonary capillaries. When they fall, they can directly enter the brain through the anastomotic branches and cause brain metastasis.
It is impossible for the doctor to cut off all these anastomotic branches. There are tens of thousands of blood vessels and it is impossible to cut them all.
In addition, the brain vascular barrier makes it difficult for chemotherapy drugs to pass through, making brain metastases from lung cancer as difficult to treat as brain metastases from other cancers.
Based on the above theory, we can reach a basic consensus among clinicians and laymen: this patient is basically doomed.
Maybe Dean Liang is now looking for Boss Zhang in the ward to discuss work-related matters?
Well, the doctors guessed it again.
This time, Dr. Song was relatively optimistic.
"It was discovered very early." Dr. Song Xuelin looked at Dr. Xie as he said this.
Dr. Xie is amazing. He discovered the patient's problem so early.
The first element of cancer treatment is to start early.
When it comes to the question of whether it is early or not, many people immediately think of cancer metastasis, and they all say that cancer metastasis will shorten the life of cancer patients.
First, we need to know what cancer metastasis is. A more accurate term should be metastatic cancer.
Cancer cells always exist in the human body. Healthy people limit their survival time, preventing them from proliferating, gathering and forming tumors, and ultimately affecting human life.
Dr. Song Xuelin's judgment on this is: "Dr. Xie may have discovered the cancer cells detached into the patient's brain for the first time, but no brain tumor was formed."
Therefore, both Dr. Xie and Dr. Qin considered the patient's brain CT scan to be ambiguous.
Based on the above judgment, patients should choose neurosurgery as the best option to detect whether any cancer cells have fallen into the brain. If so, they should be removed when they just begin to gather and proliferate, so as to achieve the same therapeutic effect as the primary cancer.
The reason why Dr. Song holds such a view is that the primary lesion of lung cancer in the patient is obviously isolated and small, which means that the disease was discovered very early.
One has to admire Dr. Xie's high vigilance, which was enough to save the patient's life.
The other doctors present nodded.
Whether cancer is discovered early or not can be classified into cancer stages in medicine.
Dr. Xie Wanying then specifically mentioned: "We need to do cancer pathology staging."
"Oh." Doctor He Xiangyu pursed her lips, feeling that the junior sister was the pathology teacher who came again.
"Pathological staging of cancer?" some doctors asked.
In the past, cancer staging revolved around surgery, resulting in pathology not determining the cancer stage but only giving a characterization of the cancer.
