Limitation _ treatment of the cancer radiotherapy technology of pancreas
Pancreas cancer radiotherapy technological to been greatly improved in recent years by itself, by two-dimentional to the three-dimension, from traditional ray to body department garmma( ) knife, the cancer radiotherapy of pancreas is suitable for the early pancreas cancer that can perform the operation, have the later period when distant place is shifted and reason apt to damage of internal organs around more to the pancreas cancer patient, the cancer radiotherapy of pancreas has some therapeutic method damaged as a, there is certain limitation in treating the later period pancreas cancer. Assign to and state pancreas cancer radiotherapy progress and limitation as follows now:
The cancer radiotherapy technology of modern pancreas: The modern pancreas cancer radiotherapy technology used for treating at present is as follows, X - knife, the intersection of three-dimension and right the intersection of shape and radiotherapy, transfer strong radiotherapy and the intersection of body department and garmma( ) knife. Slightly different in selecting to use different hospitals to formulate in the apparatus of technology, but the total principle is unanimous. Adopt X - knife or the intersection of body portion and the intersection of garmma( ) and knife, can obtain high some dosage to early the intersection of pancreas and the intersection of body and the intersection of tail and cancer of limitation, the damage organized normally around is smaller; To some tumour being big or the intersection of pancreas and the intersection of head and cancer adopt the intersection of three-dimension and right the intersection of shape and radiotherapy or it transfers strong pancreas to be relatively even in some dosage in radiotherapy in cancer, but protect and organize avoiding the high dosage and shining normally better, is shining the range safer and feasibler than under the great situation.
X - a one hundred sheets of technology:
Most pancreas cancers of clinical radiotherapy are some later period not performing the operation, tumour is relatively great, the intersection of shape and abnormality, adopt X - one hundred sheetses of very difficult to meet the intersection of tumour and dosage of characteristic, distribute the requirement treatment, so besides early limitation pancreas cancer, it is unsuitable to use X - one one hundred sheets of therapeutic pancreas cancers.
The right shape radiotherapy of the three-dimension:
Pancreas cancer is one of the research directions in the future in some later period of technological treatment of pancreas cancer radiotherapy adopting the right shape of the three-dimension.
Adjust strong radiotherapy:
The treatment technology just started, needed to accumulate the clinical experience. May get and radically treat the result to adopt this technology as to early limitation pancreas cancer, there is positive meaning to as to this carry on further clinical research.
