A puncture biopsy is the first step in tumor treatment.

Interviewed expert
Liuchen, Beijing University Cancer Hospital International Medical Department (i.e. New Mileage Oncology Hospital) imaging interventioncenter center (intervention department, imaging department) director
is good at: imaging-led minimally invasive interventional diagnosis and treatment technology, CT-led under the high difficulty site puncture and ablation treatment, each year to complete various types of minimally invasive interventional surgery two or three thousand
the time of the diagnosis: Monday morning (online appointment
) puncture resorage. Prior to this, the diagnosis of tumors is almost entirely based on the doctor's clinical experience and auxiliary examination, therefore, there are often misdiagnosis and misdiagnosis. Nowadays, the puncture biopsy can not only judge the tumor's good and malignant, but also accurately classify the tumor and detect the state of the gene mutation, taking the tumor treatment to a more accurate path.
smooth low-active nodules can be conservatively observed
the outpatient scene: a female patient in her 60s checked out and found a nodule along the lower left lung, always worried about lung cancer. Want to come to the hospital to do a puncture biopsy, but also afraid that puncture will cause the spread of cancer cells in the nodules, the whole family are very contradictory, the patient himself is also scared to sleep badly every day.
Liu Chen: From the film, your lung length of this nodule malignant degree is very low, PET-CT test shows that this part of the cell hyperplout metabolism activity is also relatively low, and you see, this thing round, very regular, so I think can continue to observe. It is recommended that you take another CT in half a year to see if it is grown up or not.
of course, if you and your family are not comfortable, you can also do a puncture biopsy, and there is no need to worry about it. Because we pierce with a kind of ballpoint pen, the pen reached the surface of the knot, the pen core pierced into the knot inside to pull out the tissue cells, and then the pen core retracted inside the pen rod together pulled out, will not touch other normal tissue.
10-month-old baby can also do a puncture biopsy
the clinic site: a mother with a 6-year-old girl to review. At the age of 10 months, she was suspected of growing a spinal tumor, and Dr. Liu Chen was diagnosed with a benign disease after a puncture and avoided an operation. Nowadays, children are able to go to school in good health.
Liu Chen: This is the youngest patient I've ever stabbed. When the child was 10 months old, always crooked neck, nuclear magnetic examination found that the first bone of her cervical vertebrae damage, thought it was a tumor, they came to me for a puncture biopsy to confirm. But it's too hard to pierce a baby, she's a little uncomfortable and she'll move, and the lesions are close to the base of the skull, where blood vessels, nerves are dense, and the risk of punctures is high.
finally, in full mahjong for the child's cervical puncture, the results show that the child did not get a tumor, but a benign disease called "eosinophilic granuloma", this disease does not have to do surgery, the bone will slowly grow well. Now the child is old, once a year to review CT, the longer the bone, the better.
false negative syllabees some need a secondary biopsy
the outpatient scene: a patient in his 60s had a puncture biopsy at the local hospital, and the results did not find tumor cells in the lung nodules. Local doctors worried about "false negative", recommended him to Beijing to find Dr. Liu Chen, and then do a biopsy.liuchen,
: If cancer cells are found in the tissue after a puncture biopsy, it is basically diagnosed as lung cancer, but if cancer cells are not found in the tissue, it may not be cancer, or it may not pierce to the area where cancer cells are found.
I have similar cases, but the vast majority are the first, many of which have been shown to be inflammation, tuberculosis and some benign tumors through follow-up treatment and long-term observation. However, if the test results show that the cancer index is very high, the external shape of the nodules is irregular, then consider the possibility of malignancy is relatively large, then I will do a secondary biopsy for the patient, but the location of the puncture into the lesions and biopsy tissue area will avoid and the first repetition.
precise control range Particle implantation effect is good
clinic site: husband due to the tumor of the tibia site caused skin ulcers, ulcers have been unable to heal, only lying on the bed, some sick friends suggested that he do radio frequency ablation to kill the tumor, his wife took the case and examination list to the clinic to ask Dr. Liu Chen to develop a treatment plan.liuchen,
: Although the patient's tumor grows on the bone, but very close to the skin, so can not do radio frequency ablation, ablation of heat will damage the skin, so that the ulcers that have occurred more and more. And the tumor is close to the anus, which is a contaminated area, it is easy to contract secondary infection, once infected ulcers are longer.
particle implantation is a minimally invasive interventional therapy technology that precisely controls the scope of treatment. For example, the diameter of the tumor is one centimeter, if i do radio frequency ablation, I have to burn out the diameter of two centimeters range to be complete, but the use of particle implantation, the range is controlled at one centimeter on the line, and the particles on the surrounding normal tissue cells killing is very small, which is the advantage of this technology.
reporter's note
see Dr. Liu Chen before, the reporter heard a lot of tumor field predecessors called him "the first piercing master in Beijing" and "Liu yi needle", after seeing me, found that he in addition to the puncture technology excellence, in the tumor treatment planning, there is a high pursuit."We now popularize the idea that for patients with early stage lung cancer, in addition to traditional surgery, radiotherapy, intervention and other treatments are also important,"
. For patients with special conditions, interventional therapy is sometimes more cost-effective. For patients with advanced and middle-stage lung cancer, we don't need to completely sweep cancer cells out of the body, so that patients learn to live in peace with lung cancer. On this basis, combined with some other treatments, patients will survive longer and have a better quality of life. Ten years ago, patients with advanced lung cancer could only live for half a year, and now, by various means, patients can live for several years. Dr. Liu Chen is here with an exhilarating look.
with the advance of interventional puncture biopsy technology, the concept of cancer treatment is becoming more and more precise. Dr. Liu Chen says the first step in effective treatment for tumors is diagnosis. "It's important that the path of cancer treatment doesn't go smoothly, and you can take fewer detours and backs," he said.
