Several common examination methods for nasopharyngeal carcinoma

The clinical examination of nasopharyngeal carcinoma is relatively simple, because it can be examined in many ways, which is very helpful for timely understanding of the condition of nasopharyngeal carcinoma. So what are the more common examination methods for nasopharyngeal carcinoma ? The following will tell you about the more common examination methods for nasopharyngeal carcinoma.

In general, the more common examination methods for nasopharyngeal carcinoma are:

Nasopharyngeal lateral radiographs, skull base radiographs and CT examinations: Every patient should be routinely examined with nasopharyngeal lateral radiographs and skull base radiographs. If there is suspected invasion of the paranasal sinuses, middle ear or other parts, corresponding radiographs should be taken at the same time. Units with conditions should perform CT scans to understand the local extension, especially the infiltration range of the parapharyngeal space. This is extremely important for determining the clinical stage and formulating treatment plans. This is a common examination method for nasopharyngeal carcinoma.

B-mode ultrasound examination: B-mode ultrasound examination has been widely used in the diagnosis and treatment of NPC. This method of examination is simple and non-invasive, and patients are willing to accept it. In NPC cases, it is mainly used to examine the liver, neck, retroperitoneum and pelvic lymph nodes to understand whether there is liver metastasis and lymph node density, whether there is cysticity, etc.

Magnetic resonance imaging: Magnetic resonance imaging (MRI) can clearly show the various layers of the skull, cerebral sulci, gyri, gray matter, white matter, ventricles, cerebrospinal fluid ducts, blood vessels, etc. It can use SE method to show T1 and T2 extension [high-intensity images can diagnose nasopharyngeal carcinoma, frontal sinus cancer, etc.] and show the relationship between the tumor and surrounding tissues. This is also a common examination method for nasopharyngeal carcinoma.

EB virus serological test: Currently, the immunoenzymatic method is widely used to detect the IgA/VCA and IgA/EA antibody titers of EB virus. The former has a higher sensitivity and a lower accuracy; the latter is just the opposite. Therefore, for those suspected of nasopharyngeal carcinoma, it is advisable to test both antibodies at the same time, which is helpful for early diagnosis. For cases with IgA/VCA titer ≥1:40 and/or IgA/EA titer ≥1:5, even if there is no abnormality in the nasopharynx, exfoliated cells or biopsy should be taken from the site where nasopharyngeal carcinoma is prone to occur. If the diagnosis is still not confirmed for a while, regular follow-up should be performed, and multiple biopsy examinations should be performed if necessary.

The above is an introduction to the more common examination methods for nasopharyngeal cancer, and I hope it will be helpful to everyone. Once you have nasopharyngeal cancer, you must go to the hospital in time and actively receive treatment in order to effectively alleviate the condition and restore your health as soon as possible.
