What are the methods for detecting small cell lung cancer

What are the methods for checking small cell lung cancer? Nowadays, there are many people smoking in society. Smoking causes many diseases, small cell lung cancer is one of them. So what are the methods for checking small cell lung cancer? Let us learn about the methods for checking small cell lung cancer.

If you want to know what methods are available for the examination of small cell lung cancer, first understand the causes of the disease:

Smoking is the main risk factor for lung cancer, and SCLC is closely related to smoking. According to a summary analysis of smoking and lung cancer worldwide from 1970 to 1999, lung cancer is positively correlated with smoking intensity (amount of smoking) and duration, and the relationship with SCLC is most obvious.

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

2. Fiberoptic 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.

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. 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.

5. Sputum cytology examination: The positive rate is related to the location and size of the tumor, the quality of the 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 not recommended for use at present.

6. Tumor VIP receptor imaging: VIP is a neurotransmitter composed of 28 amino acids with multiple functions. It can regulate the proliferation and differentiation of normal and tumor cells through its receptors. VPAC (VIP receptor) is widely present in various normal and tumor tissues, but its expression density in tumor tissue is much greater than that in normal tissue, which lays the foundation for radionuclide-labeled VIP receptor imaging. This imaging has been applied to the diagnosis, staging, treatment selection and prognosis evaluation of various tumors.
