What are the examination methods for small cell lung cancer

What are the examination methods for small cell lung cancer? When it comes to small cell lung cancer, no one knows much. In fact, this disease is more common in the elderly because they do not pay attention when they are young. So what are the examination methods for small cell lung cancer? Let's follow us to learn about it.

1. Tumor VIP receptor imaging

Vasoactive intestinal peptide (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 higher than that in normal tissue, which lays the foundation for radionuclide-labeled vasoactive intestinal peptide receptor imaging. This imaging has been applied to the diagnosis, staging, treatment selection and prognosis evaluation of various tumors.

2. Chest X-ray

It is the simplest, easiest and cheapest inspection method.

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. Sputum cytology

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.

5. Fiberoptic bronchoscope

The location, size and extent of bronchial infiltration of the tumor can be observed, and tissue can be obtained for pathological examination.

6. 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 stage of lymph node metastasis.

The above are the examination methods for small cell lung cancer. I hope it can help everyone.
