Lung cancer is the leading cause of cancer-related deaths worldwide, and its incidence is increasing among the elderly. As the population ages, the number of older adults with lung cancer will only continue to rise.

This comprehensive guide will provide an overview of the management of lung cancer in older people, including the latest treatment options and strategies for improving patient outcomes.

Epidemiology and Risk Factors

Lung cancer is more common in older adults than in younger adults. The median age at diagnosis is 65 years, and the majority of cases occur in people over the age of 70.

Risk factors for lung cancer include:

Smoking: Smoking is the leading cause of lung cancer, and the risk increases with the number of cigarettes smoked and the duration of smoking.
Radon: Radon is a radioactive gas that can be found in homes and workplaces. Exposure to radon is the second leading cause of lung cancer in the United States.
Air pollution: Air pollution, particularly exposure to particulate matter, has been linked to an increased risk of lung cancer.
Family history: People with a family history of lung cancer have a higher risk of developing the disease.
Other risk factors include exposure to asbestos, silica, and certain chemicals.

Symptoms

The symptoms of lung cancer can vary depending on the location and stage of the tumor.

Some of the most common symptoms include:

Cough: A persistent cough that doesn't go away is one of the most common symptoms of lung cancer.
Chest pain: Chest pain that is worse with coughing or deep breathing can be a sign of lung cancer.
Shortness of breath: Shortness of breath, especially with exertion, can be a sign of lung cancer.
Fatigue: Fatigue is a common symptom of cancer, including lung cancer.
Weight loss: Unintentional weight loss can be a sign of lung cancer. *咳血：咳血可能是肺癌的征兆。
Hoarseness: Hoarseness that doesn't go away can be a sign of lung cancer.

Diagnosis

Lung cancer is diagnosed with a combination of imaging tests and biopsies.

Imaging tests:

Chest X-ray: A chest X-ray can show a tumor in the lungs.

Computed tomography (CT) scan: A CT scan is a more detailed imaging test that can help to determine the size, location, and stage of a tumor.
Positron emission tomography (PET) scan: A PET scan can show areas of increased metabolic activity, which can help to identify cancerous tumors.

Biopsies:

Bronchoscopy: A bronchoscopy is a procedure in which a thin, lighted tube is inserted into the lungs to visualize the airways and collect tissue samples for biopsy.
Needle biopsy: A needle biopsy is a procedure in which a needle is inserted into the lungs to collect tissue samples for biopsy.

Staging

The stage of lung cancer is determined by the size, location, and spread of the tumor. The staging system used for lung cancer is the TNM system.

The TNM system classifies lung cancer into four stages:

Stage I: The tumor is confined to the lungs and has not spread to other parts of the body.
Stage II: The tumor has spread to nearby lymph nodes but has not spread to other parts of the body.
Stage III: The tumor has spread to other parts of the body, such as the chest wall, diaphragm, or heart.
Stage IV: The tumor has spread to distant parts of the body, such as the brain, bones, or liver.

Treatment

The treatment for lung cancer in older people depends on the stage of the cancer, the patient's overall health, and their preferences.

Treatment options include:

Surgery: Surgery is the primary treatment for early-stage lung cancer. The type of surgery performed depends on the size and location of the tumor.
Radiation therapy: Radiation therapy uses high-energy X-rays or other forms of radiation to kill cancer cells. Radiation therapy can be used before or after surgery, or as a standalone treatment.
Chemotherapy: Chemotherapy is a systemic treatment that uses drugs to kill cancer cells throughout the body. Chemotherapy can be given intravenously, orally, or through a port that is surgically placed in the chest.
Targeted therapy: Targeted therapy is a type of treatment that uses drugs to target specific molecules involved in the growth and spread of cancer cells. Targeted therapy is often used in combination with other treatments, such as chemotherapy or radiation therapy.
Immunotherapy: Immunotherapy is a type of treatment that uses the body's own immune system to fight cancer. Immunotherapy is often used in combination with other treatments, such as chemotherapy or radiation therapy.

Palliative Care

Palliative care is a type of care that focuses on improving the quality of life for people with serious illnesses, such as lung cancer. Palliative care can help to manage symptoms, such as pain, nausea, and fatigue. Palliative care can also provide support for patients and their families.

Lung cancer is a serious disease, but there are a number of effective treatments available. The key to successful treatment is early diagnosis and timely intervention. If you are experiencing any of the symptoms of lung cancer, it is important to see your doctor right away.
