For patients with small cell lung cancer and symptoms of dry cough, the treatment methods mainly include the following aspects:

1. Chemotherapy:

Chemotherapy is one of the primary treatments for small cell lung cancer. It uses chemical drugs to kill cancer cells or inhibit their growth and spread. Doctors will select an appropriate chemotherapy regimen based on the patient's condition, age, and other factors.

2. Radiation Therapy:

Radiation therapy is a localized treatment method that uses high-energy rays to irradiate the tumor area to reduce tumor volume or alleviate symptoms. For some patients with small cell lung cancer that cannot be surgically removed, radiation therapy can be an effective alternative.

3. Targeted Therapy:

Targeted therapy refers to treatment methods that target specific mutated genes. If the patient's cancer has certain specific mutated genes, corresponding targeted drugs can be selected for treatment. This treatment method is usually more effective than traditional chemotherapy and has relatively fewer side effects.

4. Immunotherapy:

Immunotherapy is a new emerging treatment method that utilizes the body's own immune system to fight cancer. By stimulating the immune system, it can help the body recognize and attack cancer cells. Although its application in small cell lung cancer is still relatively new, it has shown certain therapeutic effects.

5. Symptomatic Supportive Treatment:

For patients with advanced small cell lung cancer, symptomatic supportive treatment is crucial. This includes measures such as relieving pain, improving dyspnea, and providing nutritional support to improve quality of life. In treating small cell lung cancer, it is necessary to comprehensively consider multiple treatment methods and formulate individualized treatment plans based on the patient's specific condition. Regular follow-up and monitoring are also crucial to adjust the treatment plan in time and manage any possible complications. The ultimate goal is to control disease progression, prolong survival, and improve the patient's quality of life.
