The nasopharynx is the area behind the nose and above the throat. This is a difficult area to check, with early symptoms that are easy to confuse, making nasopharyngeal cancer less likely to be detected early. So what tests are needed to detect early stage nasopharyngeal cancer?1. What test for nasopharyngeal cancer?
In general, through clinical examination, it is often difficult to detect cancer. Therefore, in addition to the recognized symptoms, the patient will be asked to conduct a number of screening procedures and tests to diagnose nasopharyngeal cancer. Then, based on the test results, the doctor will make a conclusion whether the patient has cancer or not, along with determining the appropriate treatment direction. To diagnose nasopharyngeal cancer, patients need to do the following early screening steps:1.1. Blood test This is one of the measures to help quantify nasopharyngeal cancer markers in the blood, bringing certain value if applied correctly. In particular, the SCC plasma test is considered particularly useful, because:
Helps assess the severity of oropharyngeal cancer; Detection of metastatic status of cancer cells. As a result, doctors can prescribe the right treatment, helping to reduce the risk of more serious disease progression.
1.2. Endoscopy There are two methods of endoscopy including: traditional endoscopy and NBI endoscopy. However, traditional endoscopy uses complex light with a frequency range of 380nm - 780nm, which has the disadvantage of not being able to distinguish the difference between cancer pathology and normal areas.
Meanwhile, NBI (Narrow Banding Imaging) endoscopic technology uses monochromatic light with two narrow wavelength bands 540 nm (540 ± 30 nm) and 415 nm (415 ± 30 nm) with outstanding advantages: abnormal growth of blood vessels in the mucosal layer; For clear, sharp image results. Because NBI endoscopy helps doctors detect nasopharyngeal cancer quickly, increasing the cure rate, it is considered a modern step to help screen for oropharyngeal cancer that many hospitals have widely applied.
1.3. FNA fluid aspiration Ultrasound-guided tumor cell aspiration (FNA) is a method capable of determining the exact nature of the tumor, before the physician decides on a treatment plan for the patient. The surgeon will use a fine needle to poke through the skin into the cervical lymph nodes to aspirate specimens for cytology. The FNA aspiration sample will be sent for a biopsy to diagnose nasopharyngeal cancer. The advantages of this method are:
Ultrasound-guided procedures should be performed precisely; Patients have less pain, minimize bleeding complications; Obtain the specimen at the most suspected lesion site; Gives test results of a more obvious tumor nature without ultrasound guidance. Many cases of nasopharyngeal cancer are indicated for FNA aspiration to help diagnose promptly, even at an early stage. Since then, the treatment process is highly effective, prolonging the survival time, as well as improving the quality of life for the patient.

1.4. Biopsy This is also one of the most reliable tests for nasopharyngeal cancer because it can help:
Confirm the presence or absence of nasopharyngeal cancer cells; Accurate diagnosis of disease form and stage of disease; Assist in the selection of appropriate treatment. Especially when combined with NBI endoscopic lower dome biopsy, the test results will be more accurate thanks to finding out where the tumor appears due to the proliferation of blood vessels (the location of the lightest capture).
1.5. Diagnostic imaging The extent of tumor invasion can be assessed thanks to the diagnostic images of a number of techniques such as:
Ultrasound; X-ray; CT scan; Magnetic resonance imaging (MRI). 1.6. Biochemical tests The role of biochemical tests performed before, during and after treatment is to help assess the prognosis, as well as provide an appropriate treatment plan for each stage. Commonly tested reactions in the diagnosis of nasopharyngeal cancer include IgA/EBNA, IgA/VCA, and IgA/EA.
In addition, quantification of nasopharyngeal cancer markers or immunohistochemical tests also help to detect cancerous tumors. For example, increased CEA (Carcino embryonic antigen) is associated with ENT cancer.
