80% of the nasopharyngeal carcinoma cases of the world are in China The southern morbidity is higher than the North
Interview experts
Post-doctor, Hai Qing of China
Professor of internal medicine of tumour of the eight a hospitals of tumour centres of entire PLA in Nanjing
At 45 past 23 on August 27 Beijing time, famous Hong Kong performer " large and silly " Shing Fui-On died of illness in Hong Kong, died at the age of 54 years old because of the nasopharyngeal metabasis of cancer. It is " big and silly " Death,in society cause pay close attention to by nasopharyngeal carcinoma issue beginning response, peoples a lot of greatly, will even reach the physical examination of the hospital at once. The expert introduces, science has already nasopharyngeal carcinoma understood to some extent, nasopharyngeal carcinoma has its high-risk group, and the high-risk group check regularly, can prevent, can also find and treat in early days.
High hair reason of nasopharyngeal carcinoma
Cancer, the gene, in the foreign element, such as environmental factor (the meal, nutrition factor, chemical carcinogen) , under the function in carcinogenic factors such as some virus, radioactive rays,etc., normal cells worsen the result turned into the cancer cell.
There are sending area of the height of nasopharyngeal carcinomas in our country
Very unfortunately, our country nasopharyngeal carcinoma high to send country one of, whole world 80% nasopharyngeal carcinoma take place in our country. The southern morbidity is higher than the North.
Reason, nasopharyngeal carcinoma high rice of person who take place and in the water, contain a large number of the intersection of microelement and the intersection of nickel, cadmium,etc. and composition; In the nasopharyngeal carcinoma patient's hair, really find too healthier crowd of the content of nickel should be high. And show in animal's experiment: Nickel can promote inferior nitre amine to bring out nasopharyngeal carcinoma.
The southerner likes eating and salting the products down, there are data that show, take in the salted fish and low and split up the morbidity of nasopharyngeal carcinoma is relevant directly.
EB virus brings out nasopharyngeal carcinoma
Studies have suggested, EB virus closely linked to nasopharyngeal carcinoma.
If people infect with virus, will produce, oppose the antibody of virus in the body, and in the nasopharyngeal carcinoma patient's serum, find that there are antibodies of face-off EB virus, and quantity of antibody, from early to increase to evolution in later period constantly; EB virus exist until nasopharyngeal carcinoma live and examine, organize in a large amount still.
EB virus can enable tissue, can make it the malignant change take place not to approach human organization of primate, there is obviously function,etc. of causing tumour. According to these experimental results, someone even thinks, EB virus may be the cause of disease of nasopharyngeal carcinoma.
Shing Fui-On hometown is here " The sending area of the height "
Investigation find even high people of taking place area move far, such as moving abroad, its descendant still keeps having very high morbidity inclination; Find whole world most people infect EB virus in Childhood while being clinical, but only a minority has emergence of nasopharyngeal carcinoma after growing up. It means there is obvious ethnic sensitiveness in the emergence of nasopharyngeal carcinoma.
Nasopharyngeal carcinoma is mainly seen in yellow. The South of our country, for instance provinces such as Guangdong, Guangxi, Hunan, Fujian,etc., and some countries such as Philippine, Malaysia of Southeast Asia are the area of nasopharyngeal carcinoma in the whole world with highest morbidity. Guangdong Province morbidity of district highest with Guangzhou, Foshan, person who start, celebrate. Have 18- 27 people who suffer from this disease in the every 100,000 man, and women account for 8- 9 people. Shing Fui-On whether the intersection of Hong Kong and the intersection of Saigon and the south enclose original resident, when being high to take place to the district native place its.
In addition no matter or in low to send in the district in high person who send, can find that there is family's gathering inclination. For example find in general survey that there is so typical an example: In 49 people with three generations under one roof, 10 people suffer from cancer, 9 people among them are nasopharyngeal carcinoma. Can be thought, the inherent cause plays an important role in cause of disease of nasopharyngeal carcinoma. The investigation finds, the morbidity of person who has family's cancer medical history can reach 10%!
Nasopharyngeal carcinoma and early symptom are not obvious
In 2004, Shing Fui-On spat blood suddenly when India shot to " like horses to draw the refined star ", checked, just know to suffer from nasopharyngeal carcinoma, and has already been later period.
The patient does not have obvious symptom in early period because of nasopharyngeal carcinoma, therefore is difficult to be found. With the development of tumour, the mucous membrane of tumour takes place and breaks, infects routedly, then present symptoms such as the blood of tears,etc.; The intersection of tumour and nostril block, and swallow drum at the calibre, will appear nasal obstruction, tinnitus, the intersection of hearing and the intersection of person who drop and have a headache and symptom. Malignant degree of nasopharyngeal carcinoma is relatively high, shift the lymph node very easily, and often develop under the nasopharyngeal mucous membrane because of tumour, perhaps nasopharynx department does not have obvious tumour, but the shank has already had lump.
A lot of people's shanks have very large lump to go to the hospital to see the doctor, Shing Fui-On has used " A big tumour equally of duck's egg in the neck " To describe one's own condition. There is obvious symptom that goes to a doctor, about 70% of the patients have already belonged to later period, difficult to cure.
The high-risk group should check frequently
Prevent the intersection of nasopharyngeal carcinoma and most effective method, to find, diagnose, treat early early early.
How to carry on early self-examination? As the intersection of reason and unidentified headache of appearing, have a stuffy nose, flow epistaxis, tinnitus, throat have the intersection of foreign matter and sense symptom, has not lightened or disappeared through dealing with to the ill, or symptom is recurrent, will go to the hospital to go to a doctor soon, in order to exclude from suffering from nasopharyngeal carcinoma; Also can often touch one's own shank with hands, if can reach the lymph node, prove enlargement of lymph nodes, it lasts to be highly suspicious patient in over two o'clock person, should go the hospital make, have something to do, check immediately, in order to diagnose in early days.
The high-risk group, no matter the feeling not comfortable, must carry on the inspection one or more times every whole year. What is the high-risk group? Have the intersection of family and people of history, have three four more than people suffer from people of disease this in the family; It has to be to make serum, check, EB virus drip degrees of high people.
In all malignant tumour, the therapeutic effect of nasopharyngeal carcinoma is better. So long as the patient of the first issue gets the treatment in time, survival rate can be up to more than 80% in five years; Even the intersection of nasopharyngeal carcinoma and patient of later period, take place distant place shift in being, through putting means such as chemotherapy,etc., survival rate can also be more than 70% in five years, some patients can survive even equivalent to the normal life-span in 20, 30 years.
