Nasal pharynx cancer


Nasal pharynx cancer
fact unknown reason
By: Dr. Nasser Al-Rajhi

Nasal pharynx is the upper part of the nasal pharynx Balbelaom, a cavity located in the rear nasal cavity and deliver the nasal cavity and oral cavity or the end of the so-called Balbelaom oral. The main function of air inside the delivery through the nose to the upper parts of the respiratory system in the process Sniffling and vice Exhaling in the process. Relate to the middle ear Balbelaom nasal canal channel called Austikian operate this channel at equalizing the pressure inside the middle ear and outdoor. And nasal pharynx cancer is the growth of abnormal and uncontrolled lined by cells of the nasal pharynx, which leads to blockage in the cavity and then move to nearby parts and membrane then move across lymphatic glands in the neck and sometimes spreading tumor in various body organs, especially the liver and bone. There (offices) many types of tumors offices and nasal pharynx cancer affects, but the most common in Saudi Arabia so-called cancer (cell corticosteroids), this cancer is spreading in many areas of southern China, North Africa and the least in the Western countries. in Saudi Arabia comes tumor IX in number surgeon annually in men in general, first between the ages of 30 to 35 years, and secondly from 35 to 45 years. It is noticeable increase in the incidence of this disease in the region of Riyadh and Qassim in other parts of the Kingdom. * Causes nasal pharynx cancer: do not know the main reason leading to the nasal pharynx cancer, but there is a close relationship between him and called virus (EB Virus), as well as consumption of salted fish on the way and many Chinese for a long time. Genetics do not play a factor in this type of tumours However rare, but Chinese descent have more susceptible to infection than other races.
Symptoms of nasal pharynx cancer: many patients complain of symptoms following: blockage of the nose, as well as bleeding nose, a painless swelling in the neck and the lack of hearing in addition to headaches and pain in the neck and change in vision and coin in the face and other symptoms related Pantkalat tumor. It was here that it is not necessary that the patient complains of all these symptoms, but in most cases the complaint be brief presentations on the offer or .* diagnosis: As regard to diagnosis, it is often diagnosed patients after medical examination by a doctor specializing in diseases of ear, nose and throat examinations and the work radiological and took a sample of tumor and inspection laboratory, and then work tests to determine the stage of the disease and the extent of its spread.
Treatment: how to be chosen treatment at the stage of disease and the ability of the patient to endure. In the early stages will be used for radiation treatment alone, but in the advanced stages preferred medication as well as therapy in addition to chemotherapy radiation treatment. In some cases highly developed or deployed a main goal of treatment is to relieve pain and symptoms associated with the tumor. (Recovery), and many ask Can recovery from this cancer? To answer that, we say: Yes, thankfully, the majority of patients survive especially if discovery in the early stages, The advanced stages of healing rate amounted God to nearly 60%. worth noting that most of the cases in Saudi Arabia are diagnosed in advanced stages, after suffering with the disease nearly five months.
Prevention of this disease: at the present time there is no prevention of the disease and research under way to discover the protective vaccination against the virus of EB. The cancer does not generally can be called eating with the patient and acquired without fear of infection or disease transmission .* Tip: when injury to one or more of the previous symptoms, and continue for a period exceeding two weeks desirable to review a specialist in diseases of ear, nose and throat, where early diagnosis is ( God) main factor increasing the chance of recovery.

Immune cells to eliminate cancer nose

-- Tested soon scientists in Hong Kong and Australia experimental treatment for cancer of the nose and pharynx based on the "train" the white blood cells of the patient to fight the disease.

The researchers said team leader Daniel Chua Assistant Professor of Medicine at the University of Hong Kong tumors experiment will start in the coming three months, would be the collection of blood samples from 30 patients nose and pharynx cancer in Hong Kong.

These samples will be sent to the Medical Research Institute in Queensland, Australia, where scientists isolated a particular group of white blood cells or (T cells) for "training" to combat the disease.

The Ststnept (T-cells) are ready for battle after that and then re-injected cells entire Army again in the cancer patient.

Some categories (T cells) have a "memory". Immediately after exposing (T-cells) to the specific types of invaders and able to researchers hoped their fight against time to have the same response when it returned once again to the body of the patient.

Chua said to Reuters this week, "(We expect) to start (T cells) is a reaction very strong during this process will not only be T cells that will attack cancer cells but other immune cells the body will require to eradicate cancer cells."

And taking nose and throat cancer is strongly prevalent in southern China and the lives of one out of every three patients are believed to be related to the food-rich meals portfolio such as salted fish.

There is also a strong link between the disease, known among the Epstein Bar virus (ie BV).

Chua said that Epstein Bar virus particles exist within the nose and throat and can be trained (T-cells) to identify particles Epstein Bar virus and the immune response are urged to kill the cancerous cells in the process.

The research team knows the two types of protein particles in the Epstein Bar virus Epstein-Barr They (LMB1) and (LMB2) identified them (T-cells) with a goal in the attack.

Chua said that if this method yielded good result from these cells can be trained to attack other types of cancers linked to viruses proved to be specific, for example liver cancer associated with hepatitis C virus (Bi). Reuters
