There are many tests for small cell lung cancer

Small cell lung cancer is a major problem today. It mostly occurs in male patients. As the name suggests, small cell lung cancer is a disease of the lungs. The symptoms are mainly caused by smoking, bacteria, and unhealthy diet. There are many tests for small cell lung cancer, and we should all know them so that we can better prevent and treat it. Let us learn about the examination methods for small cell lung cancer.

Small cell lung cancer (SCLC) accounts for about 20-25% of lung cancer. According to recent epidemiological data, this type has been on a downward trend. Small cell lung cancer is the most malignant type of lung cancer and has the worst prognosis. Treatment is a comprehensive treatment based on chemotherapy, including radiotherapy, surgery, traditional Chinese medicine and immunotherapy. The disease is very harmful to the patient's body, so if you find symptoms of the disease in your daily life, you need to diagnose it early and treat it in time.

Small cell lung cancer screening methods:

1. Ordinary chest X-ray examination: It is the simplest, most convenient and cheapest examination method.

2. Chest computerized tomography (CT): It can show lesions that cannot be found by ordinary X-ray examination, and show the range and degree of involvement of the hilar lymph nodes and mediastinum.

3. Magnetic resonance imaging (MRI): It is not as good as CT in detecting small lung lesions, but it can more clearly show the relationship between the tumor and large blood vessels. When determining whether there is intracranial metastasis, enhanced MRI is the first choice. Positron emission tomography (PET): Whole-body PET is significantly more accurate than CT and radionuclide bone scanning in determining intrapulmonary masses, lymph nodes or distant metastases.

4. Ultrasound of superficial lymph nodes: SCLC is prone to metastasize to supraclavicular lymph nodes. Ultrasound scanning of the neck, supraclavicular nodes, axillae, etc. is performed to determine the lymph node metastasis stage.

5. Abdominal ultrasound, CT or MRI: The liver and adrenal glands are sites where SCLC is prone to metastasis. Patients diagnosed for the first time should undergo abdominal imaging examinations to clarify the staging.

6. Percutaneous lung biopsy: It is performed under CT guidance. The biopsy positive rate is as high as 90%. If the tumor contains a large amount of necrotic area, it is often false negative.

7. Mediastinoscopy: For cases that are difficult to diagnose with conventional methods, mediastinoscopy biopsy can be considered. It is of great diagnostic significance for upper mediastinal lymph node metastasis or anterior mediastinal lymph node invasion.
