What are the examination items for small cell lung cancer

What are the examination items for small cell lung cancer? Now many people don’t know what to do after they get small cell lung cancer, let alone what examinations to do, so they miss the best treatment opportunity. So what are the examination items for small cell lung cancer? Let’s discuss it with us below.

1. Ordinary X-ray examination of the lungs is the simplest, easiest and cheapest examination method.

2. 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.

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.

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

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

6. Bronchoscopy: It can observe the location, size and extent of the tumor infiltrating into 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.

7. Skin puncture lung biopsy: It is done under the guidance of CT, with a biopsy positive rate of up to 90%. If the tumor contains a large amount of necrotic area, it is often false negative.

8. Whole body bone scan: If a whole body bone scan indicates areas of high metabolism, the patient's medical history should be carefully inquired and combined with MRI to determine whether it is metastasis.

9. Marker examination: The main markers are NSE, CEA, SCC, CYFR21-1, etc., which lack specificity and have certain reference value for disease monitoring.
