The examination items for nasopharyngeal carcinoma are mainly divided into three types. The first type is imaging examinations, the second type is blood tests, and the third type is endoscopic pathological biopsy. Imaging examinations mainly involve CT or MRI of the nasopharynx and the whole body. If necessary, PET-CT may also be considered to clarify the extent of the condition and determine the presence of neck or distant metastases, which is helpful for diagnosis and adjuvant therapy. The second type involves blood tests, mainly including general biochemical blood tests and virus detection, which can assess the basic functional status of the body. The third type is the endoscopic pathological biopsy, which involves performing a pathological biopsy under nasal endoscopy, primarily to confirm the diagnosis and observe the extent of the lesion in the nasopharynx.

Is a fever in nasopharyngeal carcinoma a sign of deterioration?

Patients with nasopharyngeal carcinoma may exhibit fever in a clinical setting. This fever can partially be due to the worsening of the carcinoma itself. However, not all cases are due to progression of the disease; some are caused by infections and other factors. For example, after receiving anti-tumor treatments such as radiotherapy and chemotherapy, patients with nasopharyngeal carcinoma may experience a decrease in white blood cells, making them highly susceptible to infections, which can then manifest as fever. Additionally, patients with nasopharyngeal carcinoma may have weakened immune systems, making them prone to infections and fevers. As the nasopharyngeal carcinoma progresses, it can release abnormal hormones, forming endogenous fever-inducing agents, leading to clinical manifestations of fever. Generally, this type of fever is referred to as tumor fever, which is often related to the progression of the disease. Tumor fever typically requires anti-tumor treatment for effective relief.

Causes of Nasopharyngeal Carcinoma

Nasopharyngeal carcinoma is a highly prevalent malignant tumor in China, especially common in the Guangdong and Guangxi regions, as well as other coastal areas including Hunan, Fujian, and Jiangxi. These regions are among the highest incidence areas for nasopharyngeal carcinoma worldwide. The incidence rate in males is three times that of females, with the age group of 40 to 50 years being particularly at risk. The occurrence of nasopharyngeal carcinoma is associated with genetic, viral, and environmental factors, exhibiting racial and familial patterns. In areas like Guangzhou and the Pearl River Delta, it is possible for five out of nine people in the same family to have nasopharyngeal carcinoma. Infection with the Epstein-Barr virus is also one of the causes of nasopharyngeal carcinoma, in addition to environmental factors. Areas with low trace elements in rice and water, as well as low fluoride levels, are prone to higher incidences of this cancer. Patients with nasopharyngeal carcinoma typically have higher fluoride levels in their hair, and nitrites are also one of the major contributing factors to the condition.

What are the symptoms of late-stage nasopharyngeal carcinoma?

Nasopharyngeal cancer is a common malignancy in otolaryngology, primarily located in the nasopharyngeal area. In advanced stages, nasopharyngeal cancer manifests symptoms in two main aspects. One involves symptoms directly caused by the cancer or its metastasis, typically presenting as increased nasal masses, enlarged cervical lymph nodes, severe headaches, decreased hearing, and bleeding in the nasal area due to tumor cells or tissue eroding the internal carotid artery. Additionally, there is a foul smell from the nasopharyngeal area. The second aspect relates to systemic symptoms due to the growth of nasopharyngeal cancer, leading to poor overall nutritional status and cachexia, characterized by extreme emaciation. There is also the potential for distant metastasis of the tumor cells, presenting symptoms in the corresponding areas.

What causes nasopharyngeal carcinoma?

The specific cause of nasopharyngeal carcinoma, a type of malignant tumor, is currently unclear, but it is considered to be related to some high-risk factors that may lead to the occurrence of nasopharyngeal cancer. Firstly, there are cases of EB virus infections in the nasopharyngeal area. The long-term stimulation of the nasopharyngeal mucosa by this virus leads to hyperplasia of the mucosa, which can become malignant and eventually form nasopharyngeal cancer. Additionally, some clinical studies suggest that the occurrence of nasopharyngeal carcinoma is related to genetic factors, indicating a genetic predisposition to nasopharyngeal carcinoma, which leads to its development. Furthermore, some considerations involve external carcinogenic factors affecting the nasopharyngeal area, such as long-term smoking or environmental air pollution, which can also lead to a high incidence of nasopharyngeal cancer.

Is nasopharyngeal cancer hereditary?

Nasopharyngeal carcinoma is a malignant tumor of the nasopharynx, primarily found in regions populated by Mongoloid races, and is particularly common in coastal areas or in Guangdong and Guangxi regions. Nasopharyngeal carcinoma has a genetic component, meaning if you have a family history of this cancer, your chances and your descendants' chances of developing nasopharyngeal carcinoma are higher compared to those without such a family history. However, having a family history does not guarantee the development of nasopharyngeal carcinoma, nor does the absence of a family history ensure one will not get it. Under such circumstances, patients with a family history should regularly check their nasopharynx and consider whether there are traces of blood in the first sputum they cough up in the morning, which might indicate a malignancy in the nasopharynx. In such cases, performing a nasopharyngoscopy can generally clarify the presence or absence of a tumor.
