Can chemotherapy and radiation therapy be given at the same time???

Hello, generally speaking, radiotherapy and chemotherapy will not be carried out at the same time, once the blood picture drops, bone marrow suppression occurs, it is difficult to recover, it is recommended to use conservative targeting**, that is, directly inject the tumor, so that the drug does not participate in blood circulation, only kills tumor cells, dispels evil and does not harm the good, and there will be no obvious toxicity.

Of course. For example, small cell lung cancer is usually treated with concurrent chemoradiotherapy.

Hello! Colorectal cancer liver metastasis needs to be comprehensive**, and one or more of surgery, radiofrequency ablation, and chemoradiotherapy can be decided according to the specific situation; If radiation therapy is needed, it depends on the condition.

Chemotherapy and radiation therapy should not be given at the same time, and both chemotherapy and radiation therapy can lower normal white blood cells. The patient cannot afford to kill the cancer cells in ** and kill the normal white blood cells at the same time. The resistance decreases significantly.

It is decided according to the patient's condition and the patient's constitution. Some are given separately for radiotherapy and chemotherapy. Chemotherapy and radiotherapy have a large ***, which can kill normal cells while killing cancer cells.

Also, chemoradiation can cause a decrease in the number of white blood cells. So, most of them are separated. But some cases are done synchronously.

The specific plan depends on the condition and the attending physician.

Basically it will not be carried out at the same time, radiotherapy and chemotherapy are very large, and there is a lot of damage to the body, not a little damage, two at the same time, and the patient's body is generally unable to bear it. Postoperative care is also very important, and Dr. Zhang Jun, director of the Department of Oncology of Shanghai Ruijin Hospital, summarized that the importance of postoperative care is emphasized and patients are expected to comply.

Chemotherapy and radiotherapy can be carried out at the same time, and the two can play a synergistic role, but the number of patients is also increasing; Generally speaking, radiotherapy is smaller than chemotherapy, because radiotherapy is local, and the side effects it causes are usually related to the specific radiotherapy site; Chemotherapy belongs to the whole body**, using cytotoxic drugs, which have a killing effect on normal cells and tumor cells, and may cause more serious systemic reactions.

Chemotherapy and radiation therapy cannot be given at the same time; The radiotherapy will cause a smaller one, which can effectively inhibit the growth of the tumor and reduce the pain of the patient, and in recent years, the equipment of radiotherapy has been greatly improved, and the tumor cells can be shot by X-rays.

It can be done at the same time. The *** of both methods is relatively large, which should be judged according to the patient's condition, if it is sensitive to drugs, then the lethality of chemotherapy will be stronger.

Chemotherapy can be given at the same time as radiotherapy, and chemoradiotherapy can be given at the same time for advanced lung cancer, esophageal cancer, and unresectable solid diseases**. Most chemotherapy drugs such as platinum and paclitaxel have sensitizing effects, and the two can play a synergistic role.

However, in some patients, the efficacy and side effects increase at the same time, such as choking and pain in swallowing after concurrent chemoradiotherapy in patients with esophagitis, so it is not recommended for older or poorly tolerated patients to do it at the same time. Concurrent chemoradiotherapy is not recommended for early-stage and late-stage diseases. For example, small cell undifferentiated carcinoma, non-small cell lung cancer and esophageal cancer can be treated with chemoradiotherapy**.

Concurrent chemoradiotherapy should take into account both efficacy and side effects, and if the patient has more complications or is intolerant, sequential treatment can be adopted**. i.e., all chemotherapy followed by radiotherapy, or total radiotherapy followed by chemotherapy**. The specific decision should be made according to the patient's disease type, physical condition and type of drug.

Generally, the systemic effects of chemotherapy are more severe, and radiotherapy is only localized, which is relatively mild and tolerable. Radiotherapy and chemotherapy are two different means of ** tumor, radiotherapy is a local ** means, *** is relatively small, and the adverse reactions and *** brought by it are closely related to the radiotherapy site, such as head and neck radiotherapy, the most common adverse reactions are acute ** reactions and oral mucosal reactions, such as lung tumors.

Chemotherapy is a systemic method, and adverse reactions involve various systems of the body, the most common including hair loss, leukocyte decline, diarrhea and other reactions. Radiotherapy is a local means, which only brings the relevant adverse reactions of the radiotherapy site, while chemotherapy is a systemic means, and the adverse reactions include all systems of the body, so it is generally believed that the systemic effect of chemotherapy is more serious, and radiotherapy and surgery are the same, only acting locally, which is relatively mild and tolerable. Radiotherapy is local**, and the side effects it causes are related to the specific radiotherapy site, usually the side effects of radiotherapy in the chest and limbs are very mild, and the side effects of brain and abdomen may be somewhat severe, but after proper drug treatment, most patients can tolerate it.

Chemotherapy is a systemic**, which has a killing effect on both normal cells and tumor cells, and may cause more serious gastrointestinal reactions.

Therefore, the *** of radiotherapy is relatively small.

Chemotherapy and radiotherapy are two commonly used methods for cancer, and they have different mechanisms and indications.

Chemotherapy mainly kills cancer cells through drugs, while radiotherapy uses high-energy electromagnetic waves or particle beams to directly destroy the DNA of cancer cells, preventing them from growing and multiplying.

Due to the different mechanisms of the two methods, chemotherapy and radiotherapy are required simultaneously or sequentially in some cases to achieve better results.

In general, chemotherapy and radiation therapy are often used in combination in the case of cancer.

Chemotherapy can kill cancer cells, shrink the size of the tumor, and alleviate the disease, but the damage to the surrounding healthy tissues is also greater, so some cancer cells may be left behind.

Radiotherapy, on the other hand, destroys these residual cancer cells and reduces the risk of cancer** and metastasis.

In addition, radiation therapy can also prevent cancer after surgery** or reduce the size of the tumor before surgery, making surgery easier.

Therefore, the sequence and mode of use of chemotherapy and radiotherapy need to be comprehensively considered and formulated according to the specific situation of the patient, the type and stage of the tumor, and the goal.
