Is chemotherapy needed after surgery for advanced lung cancer?

Lung cancer is a malignant tumor that occurs in the lungs. Lung cancer in the middle and late stages means that the primary lesion of lung cancer is relatively large and invades the pleura, causing chest pain, chest tightness and other symptoms. It can also metastasize to the brain, liver, adrenal glands, bones and other parts, causing clinical manifestations such as bone pain, ascites, and jaundice. Lung cancer in the middle and late stages generally requires chemotherapy after surgery to prolong the patient's survival and improve the patient's quality of life.

Lung cancer is a highly malignant disease. In the middle and late stages of lung cancer, the lesions are generally larger, and local infiltration and spread may occur. Surgical treatment generally cannot be radical. Therefore, after surgical treatment, in order to further kill cancer cells, systemic chemotherapy is usually required. Chemotherapy drugs are delivered to all parts of the body through intravenous infusion, which helps reduce the chance of tumor recurrence and metastasis, relieve patient symptoms and prolong survival. Commonly used drugs for lung cancer chemotherapy include carboplatin injection, cisplatin injection, etoposide injection, pemetrexed disodium injection, etc. The above drugs must be used under the guidance of a physician.

Even in the early stages of lung cancer, when the cancer lesions are relatively localized, chemotherapy is recommended to control the progression of the disease after surgery in order to reduce the chance of recurrence. In addition to chemotherapy, other adjuvant treatments can be given to patients in the middle and late stages of lung cancer according to the condition. If the patient has a gene mutation, targeted drug therapy can be considered; if there is no gene mutation, chemotherapy combined with immunotherapy, radiotherapy, etc. can be considered. It depends on the patient's condition. Patients must insist on cooperating with doctors to take treatment, and they also need to go to the hospital for regular checkups after surgery to observe the treatment of the disease and to detect signs of recurrence early.
