Several common examination methods for small cell lung cancer

What are some common examination methods for small cell lung cancer? I believe everyone is very concerned about this issue. If you have small cell lung cancer, you must get early diagnosis and early treatment. So what are some common examination methods for small cell lung cancer? Let's take a look with us.

Small cell lung cancer is one of the basic types of lung cancer and is an undifferentiated cancer. Its pathological types include oat cell type, intermediate cell type and compound oat cell type. One-third of lung cancer patients belong to this type. Small cell lung cancer is a highly malignant tumor with poor biological behavior and a poor prognosis. Compared with other types of lung cancer with the same spread range, small cell lung cancer has a shorter symptom period before diagnosis and a shorter survival period after diagnosis.

The following checks are required:

1. Neuron-specific enolase (NSE); 2. Fiberoptic bronchoscopy; 3. Erythrocyte enolase; 4. Tumor VIP receptor imaging.

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

Fiberoptic bronchoscopy: It can observe the location, size and extent of the tumor infiltrating the bronchial cavity, and obtain tissue for pathological examination. Endobronchial Ultrasound (EBUS) is a new technology. For lesions with only airway compression but no intracavitary tumors, this examination can help clarify the extent of the lesion and improve the accuracy of transmural biopsy.

Positron emission tomography (PET): Whole-body PET is significantly more accurate than CT and radionuclide bone scanning in identifying lung masses, lymph nodes, or distant metastases.

Sputum cytology examination: The positive rate is related to the location and size of the tumor, the quality of the sputum, whether there is concurrent infection, etc. The detection rate of central lung cancer is higher, but it is difficult to determine the type, and it is currently not recommended.

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.
