"Miss Wu, do you think this patient is at risk?" Yun LAN asked softly.

When she came to the shelter hospital for a few days, Yunlan chatted with other medical staff. She somehow knew what everyone was most worried about when the shelter hospital was just established. So Miss Wu Mian was very interested in the old patient, and she naturally thought of it for the first time.

The so-called risk has many meanings from a doctor''s mouth. Wu Mian knows what Yunlan means.

"It''s not what you think," said Wu Mian, pointing to the tumor on the image. "I think the patient''s Hodgkin''s lymphoma has improved."

"I... go!" Yunlan was stunned and hurriedly came over.

But the next second, a hand pressed on Yunlan''s head, "keep a distance."

"Wearing protective clothing." Yunlan explained shyly.

"We should get used to it." Wu Mian said faintly. Then he got up and gave his position to Yunlan for her comparison.

Yun Lan was stunned. "Miss Wu, I''m afraid I can''t understand."

"It''s all right. It''s very simple. Look first." Wu Mian said, "the specific situation of the patient needs to be observed. Why in the end..."

"Is it my elder martial brother who taught patients to play taijiquan to treat cancer?"

A word blurted out, and then Yunlan felt that the atmosphere in the room was much dignified.

If this is the reason, can I devote my whole life to the research of Taijiquan and cancer treatment? Yunlan''s small head is full of wishful thinking.

A few seconds later, Wu Mian said faintly, "Dr. Yun, if you believe this, I will find time to talk to your mentor."

"Er..."

"Do you think tumor reduction has something to do with your elder martial brother''s Taijiquan? Do you really think so? Your tutor taught it in class?"

"But..."

"Do you know a term called tumor immunity?" Wu Mian stood beside Yun LAN, looked at her back and said, "doctor Yun, tell me what tumor immunity is."

The definition of tumor immunity is too broad. Yunlan concludes for a moment.

"Do you know what oncolytic virus is?"

Yunlan continues to conclude.

Her major is respiratory medicine. She has contact with other categories, but she doesn''t know much. Yunlan knows more about the concept of oncolytic virus, but she has to say it in front of the Daniel who compiled diagnostics. Yunlan feels a little timid.

"The father of tumor immunotherapy is William Collie. He found something interesting more than a century ago."

Seeing that Yunlan didn''t speak, Wu Mian explained.

"A patient with advanced cancer has been declared" incurable ", but he miraculously recovers without any treatment and lives a long life. Although this sounds like an urban rumor, the miracle of cancer self-healing in medicine is not uncommon. You are a doctor majoring in respiratory medicine. You should have seen similar patients."

"Yes, I have met several patients. One of them had tumor recurrence 3 years after right lower lobectomy. I suggested that the patient take pathology by tracheoscopy, but the patient didn''t know whether he didn''t care or thought he was hopeless, so he didn''t do examination all the time, just regular review." Yunlan immediately gave an example to prove it.

"And then?"

"Two years later, the main bronchus of the patient''s right lung has been compressed by the tumor, and the diameter of the tumor is about 6cm. But it is strange that the patient seems to survive with the tumor. There is no discomfort except occasional chest tightness and shortness of breath."

"Now it''s the eleventh year after the operation. In the past, his wife accompanied him to see a doctor, but before the epidemic, the patient came to the hospital with vigorous steps to give his wife drugs for happy and dirty diseases, and he didn''t respond at all."

"You''re talking about the survival state with tumor, which is different from tumor immunotherapy." Wu Mian felt that Yunlan was a little nervous and didn''t express his meaning, so he smiled and said, "there are more than 1000 cases of malignant tumor self-healing recorded in medical literature, and more than 80 cases of self-healing patients are recorded in China."

"Not much, Mr. Wu. Who studied it?"

"In the summer of 1890, the girl Dahir was admitted to the hospital where Collie was located because of her hand injury. At that time, Dr. Collie thought that the swelling on Dahir''s hand was caused by an abscess and gave her an abscess drainage operation. As a result, there was basically no concentrated juice. Dahir''s hand swelling was caused by sarcoma."

"Dr. Yun, what treatment would you give the patient?" Wu Mian continued to ask habitually.

"Sarcoma is highly malignant. I suggest radiotherapy," Yun Lan said without hesitation.

"There was no radiotherapy 130 years ago."

"Uh... Excision?"

"Dr. Collie used the most brutal operation at that time to amputate Dahir below his elbow.

However, this did not save the girl''s life. The sarcoma had already metastasized to her neck and abdomen.

Within a year, Dahir died at home. Dr. Collie has been observing the evolution of Dahir''s condition in the process. "

"I don''t know why. Some people say that Dr. Corey may have fallen in love with the girl, but... Not to mention this, he read a lot of information after Dahir''s death and found many doctors to pursue similar cases, trying to find a way to treat sarcoma."

"But Dahir is dead."

"If I go on, you''ll know." Wu Mian said faintly. "Later, a case attracted Dr. Collie''s attention - a patient with soft tissue sarcoma healed himself. Dr. Collie found the patient and inquired about the medical history in detail.

Note that this is a knowledge point. If you encounter similar situations in the future, it is very important to ask about the medical history. "

Wu Mian automatically switches to teacher Wu''s state.

Yunlan nodded as if she were in class.

"When the patient was dying, he was infected with Streptococcus again. At that time, his family and graveyard were ready and waiting for him to die. But it is strange that the sarcoma on his neck shrunk when the patient''s immune cells fought with the bacteria.

When his streptococcus was completely killed, the soft tissue sarcoma magically turned into an irrelevant scar. "

"Later he began to study immunotherapy?" Yun LAN asked in surprise. "It''s too early."

Immunotherapy is a kind of treatment for tumor which has sprung up in recent years.

Even now, immunotherapy is not mature and is still in the exploratory stage.

Yunlan never thought that as early as 130 years ago, some doctors had begun to think about immunotherapy.

This is so advanced that Yunlan can''t accept it.

"After a large number of literature review, Dr. Corey also found 47 other similar cases.

At that time, he speculated that bacterial infection would trigger an immune response, making the patient''s body actively attack cancer cells.

His idea is similar to Pasteur''s vaccine - if accidental infection can sometimes recover cancer, why not deliberately create some infections to treat cancer? "
