The large intestine cancer(include colon cancer and rectum cancer) is one of the familiar tumors, in the west flourishing nation in order to rank the first to the malignant tumor of the fourth, gradually rises in recent years in the our country its outbreak rate, have become the malignant tumor of the fourth or the fifth currently, Shanghai City is large intestine cancer Gao Fa Qu.
Has all large intestine a cancer around at the our country rectum cancer of 2/3 or so.The surgical operation excision is a rectum cancer head the treatment method for choose, but because the rectum is located on narrow and small basin a chamber, relate to with urine bladder, urethra, reproductive organs and pelvis closely, cut off scope to be subjected to restriction, tumor growth in the process easily and outside invade surroundings dirty machine, the part relapses a rate after the Shu higher, cultural heritage reports to about 6% ～s 40%, the most is in 10% ～s 20% be or so and win the case in later period to be up to 30% among them.Part's relapse will cause a chamber and meeting private parts acute pain etc. symptom, patient pain and sufferings unbearable, serious influence life quality, and easily erupt urethra to accumulate water, is a rectum cancerous of main cause of death.
The treatment that the part relapse is very difficult, extension again excision be suitable for a handful of patients, and surgical operation risk big, curative effect bad;The partial outside projects treatment and can have appeasement of alleviate the condition function, have a possibility of appear the complicationses, such as radio bladder inflammation and small intestines boring...etc.;The effect of the chemotherapy also badly.
Project the treatment(outside project) is a rectum cancer currently Shu empress part relapse of main treatment method, it carries on the X of high strength to shoot line irradiation to the cancer organization, but in the meantime it surroundings of normal the organization also inevitably suffers from the harm of different degree and cure a rectum cancer part to relapse a focus of in the meantime, rectum surroundings of normal organization such as the small intestines, urine bladder...etc. also are subjected to obvious hurt, have already appeared complicationses, such as radio bladder inflammation and small intestines boring...etc. of possibility, the bear of small intestines is subjected to quantity lower, make the amount of of outside emanation pass to increase to be subjected to restriction but influence to the control of tumor.Some new techniques are like proper form and adjust currently strong put to treat to technically open an exhibition, can raise tumor organization quantity, reduce it surroundings normally organize of be subjected to quantity, but small intestines because of it ambulation and bowel chamber capacity of can the variety make these lately technical applications be subjected to restriction.And the radio grain son transplant a treatment method, is partial according to the distribute of all of the appearances and decision grain sonses of tumor total the amount of is all good enough to make surroundings(valid the radius about 1.7 the Li rice/grains son) cancer the cell thoroughly kills to put out, and because of radio grain sub- strength the Shuai reduce with distance square become inverse ratio, past it to surroundings organization of the harm be smaller and around normally organize almost have no hurt, more and so protected normal organization, so is also a kind of proper form to put to treat.
Radio grain son's transplanting close quarter to put to treat is Euro-American to quickly develop with domestic in recent years of tiny create the treatment tumor new technique, that technical characteristics is according to the appearance size of tumor, while cure the instruction of plan the system(TPS) glint grain the son transplants tumor organization an in common use emanation grain son to seal completely for the titanium metals according to the plan of the diameter be 0.8 millimeters, the length is 4.5 millimeter sons with 125 grains of iodine －s, the у which makes use of it to release shoots line to carry on the tumor keep on the irradiation of low doses, kill to put out tumor cell, can make to"proper form project light upon" of the tumor, with maximum limit control the growth and development of tumor.That technique is also called r knife inside the body.The emanation grain son transplants a treatment tumor technique, the abroad has already carried on an extensive research in the prostate gland cancer, only have a handful of reports in the rectum cancer, and the domestic also just openned an exhibition this new technique.
Reply the Dan university belly surgery of the tumor hospital associate professor Zhao4 Guang3 Fa3 surgical operation and iodine － 125 grains of sons transplant to combine together, to rectum cancer the part relapses a case adoption surgical operation excision after the Shu+remain of the iodine － in the focus 125 grains of sons transplant close quarter to put to treat.From the case cured currently with visitted a result to see, have better curative effect, parts of cases have already survive two years above, tumor have no further development.
That method is applicable to inside the cancer after operation small pelvis, belly cavity of the treatment rectum or meeting private parts etc. of the part relapse, but not the companion have distance to transfer.
Cure a project:Surgical operation ago according to B super, X line, CT and MRI etc. image learned data, built up the 3D picture of tumor, from plan system the emulation can't cut off respectively, under part of excision etc. circumstances of different degree of the grain son distributes a plan, the grain son which builds up various tumor appearances distributed plan database, in the surgical operation according to appearance and B of tumor super, X line etc. image check, choice plan database in suitable of treatment plan, assurance grain the amount of the son with distribute, the reasonable transplants a grain of son:(1)For the tumor of ability parts of excisions, transplant iodine － 125 grains of sons with edge in remain of the focus after with maximum limit cutting off tumor;(2)To the tumor that completely can't cut off, then according to TPS treatment project before the Shu, transplant iodine － 125 grains of sons with edge in the tumor substantially;(3)The tumor remained to the slice forms, such as blood vessel and urethra...etc. can adopt iodine － 125 grains of sub- living creature gums to glue to stick and sew up...etc. to wrap a method treatment of round the tumor.Carries on B empress the Shu super for a month, X line and CT with visit, understanding grain son distributes and moves a circumstance and planned to carry on a comparison ago at the Shu.For have never once accepted to put to treat of relapse a case, can according to pathology and relapse a circumstance to give before the Shu or the low doses outside project light upon a treatment after the Shu and give when it's necessary chemotherapy.
