The magnetic resonance can help the nasopharyngeal carcinoma patient to be accurate by stages
The clinical treatment of nasopharyngeal carcinoma in Guangdong Province makes the new break-through
A few days ago, the seminar which tumour Vice President of centre of prevention and cure, radiotherapy horse fine horse's professor of Zhongshan University headed, with the project " The complex treatment of nasopharyngeal carcinoma based on modern image technology is studied and employed " Win the second prize of Progress in National Science and Technology of 2009. Clinic changes, radiotherapy technological innovation by stages These are original to study what will be brought to patient on earth to change? He has introduced to the staff reporter in detail.

The magnetic resonance is chosen first by stages for clinic
"The clinical phased standard of nasopharyngeal carcinoma of the 1990s of last century can only rely on simple clinical examination and CT to diagnose, can't reflect the severity of disease accurately, there is certain limitation, unable like treating competence ' grow with each passing hour '. And the phased standard used extensively in the world is mainly made according to the western case characteristic by the western researcher, this is different from condition development characteristic of China's case. " Professor Ma Jun says.
He introduces, the seminar passes the finding: MRI (magnetic resonance) Can more clearly reveal the infringement of the deep department structure in cranium bottom ossicle, cranium nerve and cranium,etc. than CT, thus has defined MRI reveals nasopharynx has illness coming on in the cooking stove, carries on the clinical and phased first-selected method originally, this makes the doctor more pointed on the choice which treats the tactics. "After adopting MRI, 40% of the nasopharyngeal carcinoma patients have changed clinically by stages, 3/4 of the cases among them are the condition been underestimated. Thought it was the early reality that already entered middle period, thought middle period has been actually already to later period, the intensity that therapeutic at this moment is without keeping up with, it is difficult to control the condition. " He says.
In addition, still lacking some patients has been misdiagnosed and has accepted the excessive treatment for later period. "This means not only the economic expenses increase, the unnecessary poisonous side effect appears, may even lose hearing. " Associate professor of treatment Sun Ying, main member of seminar, says.
Meanwhile, study yet to find, nasopharyngeal carcinoma has " the lymph node is shifted after swallowing " omitted in phased standards now This factor has important influence on prognosis, should include it in lymph node by stages together; And tumour is infringed simply to the oral cavity or nasal cavity and had considered as in the past " The bad prognostic factor " ,But the real therapeutic effect is better at present, should give " demote " . "The above academic view is the authoritative international anticancer alliance - -Seventh clinical phased standard of federation, cancer of U.S.A., adopt. This is the originality research results coming from China in the international phased standard of nasopharyngeal carcinoma too. " Professor Ma Jun introduces.
" the individual has wild abnormality "
It is damaged that radiotherapy reduces
"The nasopharyngeal carcinoma patient must draw the regular rectangle to orient on the face before radiotherapy in the past, some tumour cells will be omitted, but some normal tissues are damaged because of unnecessary radiation. " Professor Ma Jun introduces.
For this reason, they have first developed " individual's abnormality is wild " at home Radiate the treatment technology, thus protect normal organs such as brain stem, eyes, oral cavity around,etc. effectively. Chief physician Luo Wei, main member of seminar, introduces, under the situation of the apparatus in short supply at that time, this technology is very practical, and the hospital at the basic level nationwide should spend a lot of years to popularize. Confirm through the 10 -year long clinical result, this technology has obviously improved long-term curative effect, reduce the intersection of tongue and amyotrophy, swallow difficult, damage.
"Though the radiotherapy is the main treatment means of nasopharyngeal carcinoma, it is a part treatment, can't solve all problems. " Professor Ma Jun introduces, the prospective clinical trial of nasopharyngeal carcinoma is found in later period in they are through 312, radiotherapy complement chemotherapy reduce 7.8%, total survival rate, raise the intersection of distant place and person who shift by 10.1% with the same period, can strengthen and radiate the result of treatment.
In addition, they also find, induce chemotherapy to relieve symptoms such as headache, epistaxis,etc. fast before radiotherapy, can also control tumour to develop as soon as possible. "It is there aren't group after cooperating with clinical tumour in the Asian-Pacific area not to unite we,complement in order to can last chemotherapying radiotherapy in on the later period patient disease -specific survival rate last 8.2%. At present, radiotherapy complements the standard treatment of nasopharyngeal carcinoma treatment of later period while already becoming in complex treatment of chemotherapy mode. "
