Can CT detect the early symptoms of nasopharyngeal cancer?

CT is still very important in the diagnosis of nasopharyngeal cancer, but if you want to rule out early nasopharyngeal tumors, the following items should be checked: first, nasopharyngeal endoscopy should be checked: nasopharyngeal tumors can generally be found, and if there is a suspicious situation, pathology can also be taken by the way (pathology is the gold standard for diagnosing tumors); Second, you can check the blood for EBV antibodies (most nasopharyngeal carcinoma is related to EBV infection), and if it is positive, you should be vigilant; Thirdly, if necessary, an enhanced MRI scan can be done (MRI and CT have their own advantages in imaging, and MRI seems to be more advantageous in the diagnosis and staging of nasopharyngeal carcinoma).

If there is no abnormality in the above, then nasopharyngeal cancer can be basically ruled out, of course, if there is a nasopharyngeal tumor, it can generally be found in time. If it helps you, thank you!

If CT finds something growing in the nasopharynx, but the specific nature cannot be determined, pathology is needed to confirm the diagnosis of nasopharyngeal cancer. If the CT doesn't find anything, then you can rest assured.

Now the mainstream ** way is as follows.

1.Posterior rhinoscopy.

Convenient and easy. Small nodules or granulomatous bulges may be seen in the pharyngeal recesses and anterior nasopharyngeal parietal walls, with rough and uneven surfaces, prone to bleeding, and sometimes submucosal bulges. Atypical early lesions may only present with mucosal hyperemia, vascular distension, or fullness of one pharyngeal crypt, which should be considered.

2.Fiber nasopharyngoscopy.

It is beneficial to detect early minor lesions, especially for patients with strong gag reflex or difficulty opening the mouth, and if suspicious lesions are found, biopsy should be performed in time.

Viral serology.

As an auxiliary indicator for the diagnosis of nasopharyngeal carcinoma. It can be used for EBV shell antigen, EBV early antigen, EBV nuclear antigen detection, etc.

4.Exfoliated cell test.

Generally, under local anesthesia, specimens are taken in the nasopharynx as smears to check for cancer cells, and the detection rate can reach about 90%, which is close to that of biopsy. Exfoliative cytology combined with serology can be used as a screening feature.

5.Biopsy.

It is the basis for the diagnosis of nasopharyngeal carcinoma, and the submucosal tumor tissue can be taken for pathology through the nasal cavity or oropharyngeal approach, and the submucosal tumor tissue can be taken from the submucosal tumor tissue for pathology through the nasal cavity or oropharyngeal approach.

6.Cervical lymph node palpation and biopsy.

Palpable lymph nodes that are hard, immobile or immobile, and enlarged in the deep upper neck. If the patient has cervical lymphadenopathy and no obvious suspicious lesions on nasopharyngeal examination, and multiple nasopharyngeal biopsies are negative, a neck biopsy may be considered to confirm the diagnosis. Usually the neck mass puncture and aspiration is used for cytology, if necessary, the neck mass can be considered, and the tissue can be taken for examination, and it is best to select a single enlarged lymph node, all of which are extracted for pathological examination to prevent the cancer from spreading.

According to its pathological type, to determine its primary lesion.

7.Imaging tests.

Computed tomography (CT) and MRI are useful to understand the extent of tumor invasion and the extent of bone destruction at the base of the skull. If possible, PET-CT or PET-MRI can be done.

CT nasopharyngeal carcinoma diagnosis is important to exclude early nasopharyngeal tumors, and the items to be examined: first, nasopharyngeal endoscopy: nasopharyngeal tumors can be found if there is a suspicion, and pathology can be taken by the way (gold standard for pathological diagnosis of tumors); Second, check the blood for EBV antibodies (several nasopharyngeal carcinoma EBV infections), and be vigilant if positive; Third, it is necessary to do an enhanced MRI scan (MRI and CT imaging surfaces of various nasopharyngeal carcinoma diagnosis and stage areas seem to be more advantageous), all are different, basically rule out nasopharyngeal carcinoma, nasopharyngeal tumors, and can find your help, thank you.

CT findings of nasopharyngeal carcinoma are: early small submucosal tumors may appear as shallow pharyngeal crypts on one side or flattening of the Eustachian tube key; If the tumor is larger, the lateral notch of the nasopharyngeal cavity on the affected side will be flattened and disappeared, the posterior wall of the eustachian tube will be bulging and thickened, and the nasopharyngeal cavity will be deformed. Masses may invade the nasal cavity, sinuses, infratemporal fossa, and orbits; The tumor may spread along the eustachian tube to the middle ear and into the brain through a rupture hole or a cranial suture; The tumor may spread to the upper hall, jugular vein lymph nodes, and retropharyngeal lymph nodes.

Nasopharyngeal carcinoma is a malignant tumor that occurs on the roof and lateral wall of the nasopharyngeal cavity. It is one of the high-incidence malignant tumors in China, with the highest incidence of otolaryngology malignant tumors, and the incidence rate in men is about 2 3 times that of women, and 40 to 50 years old is the high-incidence age group.

If you are unfortunate enough to suffer from nasopharyngeal cancer, early detection of symptoms and early detection of symptoms is very important, and the 5-year control rate of early cases of nasopharyngeal cancer is as high as more than 90%.

Seven symptoms of nasopharyngeal cancer.

2.Tinnitus, ear tightness, hearing loss: When the lesion occurs on the lateral wall of the nasopharynx or the mouth of the Eustachian tube, the tumor compresses the Eustachian tube and can cause unilateral tinnitus or hearing loss, catarrhal otitis media, etc.

3.Bloodshot nasal discharge: Most patients retract from the nasal cavity backwards to suck out bloody nasal discharge, which is spit out from the oropharynx, which causes a high chance of missed diagnosis and misdiagnosis.

4.Nasal congestion: mechanical nasal congestion occurs due to tumor occlusion of the posterior nostrils, and advanced tumor enlargement can cause nasal congestion on both sides.

5.Dysphagia: As the tumor progresses, it can compress the glossopharyngeal, vagus, accessory, and hypoglossal nerves, resulting in dysphagia, vocal cord paralysis, and tongue atrophy and deviation.

6.Vision problems: The tumor spreads intracranially, and facial numbness, diplopia, blurred vision, drooping eyelids, and strabismus may occur.

7.Cervical lymph node metastasis: 60%-90% of patients with nasopharyngeal carcinoma have swollen lymph nodes, the lump is located in the upper neck, and the ** sex gradually grows and the texture is hard.

How to prevent nasopharyngeal cancer?

1. Pay attention to climate change, prevent colds, maintain nasal and throat hygiene, and avoid viral infection of nasopharyngeal cancer.

2. Nasopharyngeal diseases should be diagnosed and treated as soon as possible, such as nasal discharge with blood or vomiting bloody nasal discharge from the mouth after nasal suction, as well as unexplained cervical lymphadenopathy, middle ear effusion, etc., should be examined in detail in the nasopharynx in time.

3. Try to avoid inhaling harmful smoke, such as kerosene lamp gas, insecticidal aerosols, etc., and actively quit smoking and drinking.

4. Eat more foods that have anti-cancer effects and improve immune function in your diet: such as cauliflower, kelp, fungus, eggs, onions, etc.

The early symptoms of SPAN nasopharyngeal carcinoma should be noted, usually there are 1Swollen cervical lymph nodes: a lump appears on one or both sides of the neck, which is incompetent, hard, and has poor mobility, and is often mistaken for lymph node tuberculosis or lymphadenitis.

1.Headache, which can be present in the early stage, and is mostly sideways and intermittent; In the later stages, there is a persistent severe headache, which is easily mistaken for neuropathic.

Migraine. Bleeding, mainly with blood in the posterior nasal ligament, or bloody nasal discharge from the nose. At the beginning, it is often a small amount of blood, which is easy to be ignored, and when the amount of bleeding is large, the lesion is often in the middle or advanced stage.

3.Other symptoms, in addition to one or all of the above symptoms, can also appear nasal congestion, ear closure, tinnitus, numbness, diplopia, sagging and other symptoms. Advanced cancers are prone to intracranial invasion and distant metastases to bone, liver, and lungs
