What are the treatments for lung cancer?

Although some people often hear about lung cancer in their daily lives, they are not very clear about the relevant knowledge of lung cancer. So how much do you know about the treatment of lung cancer? Next, let the experts analyze the chemotherapy of advanced lung cancer for you so that you will no longer be unfamiliar with it.

Chemotherapy for advanced lung cancer is to deliver drugs to the whole body through blood vessels, affecting all cells in the body. Chemotherapy for advanced lung cancer is mainly carried out in three ways in clinical practice: one is systemic chemotherapy for advanced or disseminated tumors, the second is local treatment of small lesions that have metastasized after surgery or radiotherapy, and the third is for patients who cannot undergo surgical resection or radiotherapy. The use of chemotherapy before surgery or radiotherapy can shrink the tumor, reduce the scope of resection, and improve the patient's survival rate.

However, since chemotherapy drugs for advanced lung cancer have huge toxic side effects, while killing malignant cells in the human body, they also kill normal cells, especially immune cells, destroying the immune system of cancer patients and giving cancer cells a chance to "revive", requiring treatment again, which accelerates the patient's death.

What are the complications of primary lung cancer?

Bone metastasis of lung cancer is mostly osteolytic destruction, while small cell undifferentiated carcinoma and a few adenocarcinomas may show osteoblastic destruction. Among patients, 86% have osteolytic destruction, 7% have osteoblastic destruction, and 7% have mixed destruction. The incidence of primary lung cancer complicated by hypercalcemia is 26%.

Chemotherapy

Systemic chemotherapy can control the development of bone metastasis and relieve pain while treating primary lung lesions. Therefore, it can not only relieve pain, but also kill cancer cells and control their growth. In particular, the combined chemotherapy regimen based on high-dose cisplatin is more effective. In some cases, when rechecking X-rays, it was found that bone metastases disappeared and new bone cortexes were formed. Since there may be potential micrometastases in other organs of the body when lung cancer cases have bone metastases, systemic combined chemotherapy can also have a therapeutic effect on other potential metastases while treating bone metastases. At this time, fat-soluble small molecule drugs can be used, such as elemene liposome injection green chemotherapy drugs.

Radiation therapy

Radiotherapy can be divided into several methods such as cobalt-60 irradiation, deep x-ray machine and linear accelerator. For isolated bone metastases, after the lung lesions are controlled and stabilized by chemotherapy, high-dose, short-course radiotherapy can be given to relieve pain, kill cancer cells and control the development of lesions. About half of the patients can completely relieve pain after radiotherapy, and about 75% of the patients can significantly reduce pain.
