The treatment discussed a rectum cancer

The knot, rectum cancer are the second familiar tumor of flourishing nation.Have annually in England 30,000 add a clinical diagnosis case, among them, nearly 45% case occurrence are in the rectum and the B form colon.The last few years rectum cancer had substantial progress in curing the surgical operation and the assistance and give thus rectum cancer the sufferer's treatment brought to very greatly change.
Surgical operation technique
The distant rectum tumor is to pass stomach would the Yin consociation rectum cancer cure for good a Shu treatment, but in order not to the stomach wall permanence build Lou and continuously increase to the resection method with previous tumor usage of"low" in the near future.The former concept points out that the boundary of distant excision musts be and can describe a tumor boundary surroundings at least 5 Li rices outside, this concept has already lost authority.Unless the tumor divide bad, so distant slice good luck to be apart from tumor to descend good luck 2 Li rices all right already, because the tumor distant bowel wall inside proliferation seldom more than one Li rice, distant lymphoid in the meantime spread also seldom.If bowel wall proliferation exceeds tumor scope one Li rice above of, explain the tumor has already develop till later period and have already had distance to transfer.This ories make progress and fits together the application of machine, to medium degree the rectum cancer for divide, have never need to follow tumor to learn a principle, allow is only being apart from ass Gua about muscle good luck 2~3 Li rices above go to fit together Shu.The colon － of the low rectum, or the colon － anus tube fit together Shu to avoid going the stomach wall permanence to build Lou Shu, but also can cause in the meantime bowel peristalsis the frequency increase, inside nasty empress heavy with move bowels incontinence.(ex- resection comprehensive advertise for)Create one short of 5 Li rices the ～ 7 Li rices colon J form keep bag(the principle up equals ulcer colon burning return to bowel to keep bag) and improved a low the function which fit together a bowel way, but had no increment surgical operation complications.Another colon keeps bag to take shape a method, be fit together on the above of 4 Li rices ～ 6 Li rices, follow colon Zong stalk to cut open 8 Li rices ～ 10 Li rices and walk sideways a pair of layers to sew to shut.This method has already been prove after the low fit together ameliorable bowel way function.
The main progress of surgical operation technique is an attention's clearance for tumor.The rectum fastens a film lymphoid organize from fat organization and rectum reflux of rectum surroundings constitute.Fasten a film from tumor corpus to the rectum of 3 Li rices in the distant place in can discover isolated tumor deposition.The whole rectumses fasten after the film resection part to relapse a rate low at 10%, but fit together a people a fission rate to rise to 19%.Fit together a people's fission has something to do with rectum remnants carrying a blood luck to stop, clinical ascend the usually applied temporary sex bowel build Lou Shu(usually is to return to bowel to build Lou) to reduce the complications that the bowel Lou cause.
To having already spread the tumor which organizes beside to the rectum can not completely the clearance will cause the increment be partial to relapse a rate(78%).Slice the good luck surroundings flat surface organization thoroughly clearance is another important factor that the rectum cancer cures for good Shu.At Japan, clinical fulfillment prove, the basin close account with lymphoid chamber sweeps Shu after of the existence rate doesn't surpass whole rectumses to fasten film resection, and causes urine bladder and sexual function obstacle incidence rate is higher.Not and extensively support this ory's break in the western nation.
After cautiously choosing to the sufferer particularly is an advanced age the sufferer or companion contain other serious paroxysm sufferers and the partial excision is a kind of reasonable way.Go to dentation line above, 10 Li rices following tumor probably at orthoptic under excision, however more distant pathological changes' can pass be shown minute details a surgical operation treatment by the mirror in the ass bottom.This shows minute details surgical operation to pass a rectum mirror a realization, use carbon dioxide to note spirit in the rectum, similar cure at the belly cavity mirror.This resection is applicable to point less than 5 Li rices, easy to distinction of check diameter of tumor sufferer.The rectum mirror descends super voice and CT to scan to help the certain tumor to invade bowel wall of depth tie the department be lymphoid to knot a circumstance.
The advance guard lymphoid knot is the first(station) lymphoid knot that the guide line flows to deliver tumor at first, it drive think most probably the containment transfer cell.99% rectum cancer cases can be accurate to position its advance guard lymphoid knot.Theoretically these pour a flattering examination(possible usage member technique) and probably raise tiny transfer of detection, but the advance guard be lymphoid to knot in the mammary glands cancer and the clinical application of the melanin lump of experience tell us, it not too may provide more important meaning for the surgical operation technique of the tumor clearance.
As for liver transfer
The rectum cancer existence the liver transfer of the sufferer prepare behind very bad, among them, the existence expect for 6~9 months and make use of 5 chemotherapies of － Fu can increase to 12 months.Though usage such as depend on sign can a little bit raise an existence rate for Kang and the new chemotherapy medicine of the Ao sand benefit platinum, but the chemotherapy only palliate.
The liver transfer can go to cut off surgical operation of only have 10%, but the surgical operation provided the only healing hope for the patient.Tumor focus proliferation has been already invade and important and dirty machine structure of, like liver door, is the taboo certificate of surgical operation.
Along with people are to thorough understanding that the liver dissect, surgical operation and anaesthetize a technical exaltation, round a surgical operation period to die just for 2% currently.The liver includes eight liver segment and each liver segments have vein and the liver afferent blood of its own liver tube, door to provide, so each liver segments can be independent to be cut off.Application in the surgical operation super voice the knife(the super voice be substantial to dissect knife) can reduce afferent breakage with argon gas knife(the argon gas deeply hot method) and the control centre vein presses down to decline.Sometimes can avoid a blood transfusion.
Liver part cut off consociation an assistance a chemotherapy more valid.Liver after the parts of resection, the infusion chemotherapy of the liver artery medicine, combine a system chemotherapy to compare pure surgical operation the excision equally prolongs existence time for 2 years.The system chemotherapy can contract a physical volume of transfer the focus, existence rate and standard resection future trouble existence rate for 5 years compare later on and make 16% can't the surgical operation cut off of the tumor may go a surgical operation treatment.Recently, European cancer research treatment the organization(EORTC) under way tests to evaluate before the Shu with Shu after the chemotherapy is to the function that can cut off liver to transfer cooking stove a sufferer.
The new surgical operation method,such as the cryotherapy and the radio frequency , removes Shu and may be meaningfully.The cryotherapy can be use to cure physical volume's above 8 Li rices, include in the tumor of important structure surroundings and the cancer organization is destroy in the refrigeration, defrost again and again the process.But, its weakness mainly includes issue of blood and the system is hot to hurt reaction and remain bad dead organization.The radio frequency removal Shu is an usage emanation frequency to project light upon to produce calories at the partial organization, although it treatment tumor of the physical volume be limited, immediately of the complications want compare low temperature treatment little.Two kinds of methods all can damage cancer organization, but the influence of them upon the long-term existence rate still keep needing a further observation.
Chemotherapy with put to treat
Chemotherapy with put to treat of assistance function:Whether possibility and evaluation goes to protect anus surgical operation or not canned lower the part of rectum cancer to relapse, raised surgical operation excision.Before the Shu put to treat can relapse part a rate is declined to 11% by 27%, make the long-term existence rate raising to 58% from 48%.Make use of whole rectumses to fasten film resection to plus before the Shu put to treat can relapse part of the incidence rate decline to 2%.Before the Shu put to treat is safe:Though it may delay heal of meeting private parts, cause sexual function obstacle, but the chemotherapy doesn't easily cause to fit together a people's fission before the Shu.Shu's putting to treat behind apparently can't raise a long-term existence rate, and cause various complications, especially small intestines Geng Zu diarrhea with late hair cause by radio enteritis, but Shu behind put to treat can also reduce tumor part to relapse.The advantage of chemotherapy lie in the life that can prolong surgical operation effect or pathologic result a dissatisfied patient after the Shu.
Unite a chemotherapy and put to treat a method(put, chemotherapy) just extensively applied after the rectum cancer patient of before the Shu, Shu.Rectum cancer cell to put to treat a period to make use of 5 － Fu chemotherapy functions sensitive very.Put, chemotherapy consociation treatment with go emanation treatment to compare alone, the former can consumedly reduce part to relapse a rate and raise an existence rate.The rectum cancer sufferer reflects for better 5 years towards putting before the Shu, chemotherapy, existence rate and lowerly relapse a rate.
