Fallopian tube cancer diffusion and metastasis
One of the reason of the most that the malignant tumor is hard to cure for good is the feature that it has a metastasis.The metastasis is the swollen oncocyte that the digit has already gradually shed off, pass some paths or outlet and attain with at first deliver cooking stove not connect with each other even keep off the process of part growth;Originally the tumor of part growth calls to deliver a tumor at first and transfer other parts grow of tumor call after hair tumor or metastasis neoplasm, also call trochanter neoplasm.
Transfer process
The metastasis of swollen oncocyte is many processes with continuous dynamic states of stages.The swollen oncocyte encroaches upon to break tissue natural cover into first blood vessel, lymphatic vessel formation cell embolus, immediately shed off and circulate in the blood or the lymphatic vessel, and then attach, stop over with dirty endothelial cell mucopeptide of the machine microcirulation in the distance, and wear proptosis microcirulation, breed in the new tissue organ the parenchyma, the growth become new metastasis neoplasm.In addition and in the process of transfer in, the carcinoma cell can also directly be shed off in body cavity and the nidation becomes the implantation metastasis neoplasm at the serous membrane, serosa face form.
Transfer path
The metastasis of malignant tumor mainly passes lymphatic vessel, blood vessel and body cavity.The blood vessel mainly passes a vein and seldom pass an artery first.
1.The lymphoid way transfer:The lymph metastasis presses the regulation metastasis of lymphatic trunks more, namely or so upper part of root or rhizome neck trunks, left right subclavian trunk, left right bronchomediastinal trunk, left right lumbar trunk and intestinal trunks.
2.The blood way transfer:The blood way metastasis presses body vein type, pulmonary veins type, portal vein type, the awl vein type and against the current type more.
3.Plant a metastasis: The swollen oncocyte diffuse grows in the antrum Xi, like thoracic cavity, belly cavity, pericardial cavity…etc..The surgical operation, puncture process can also result in the implantation transfer.
Affect the factor of metastasis
(1)the tumor partial factor:Include a tumor size, grow speed, divide degree, pathologic type, swollen oncocyte metabolism feature, kinematic ability, year welfare, enzyme of creation, surface structure and the afferent formation of the electric charge, tumor lead a property, carcinoma cell DNA
The change etc. of structure.Under the general circumstance the tumor is more big, malignant the degree be more high and grow speed more quick, more easy metastasis.
(2)whole body factor:Malignant tumor in addition to be subjected to a partial factor in addition to affect, also be subjected to the influence of many whole body factors, mainly have:The action of ? immunity:The machine body immunity action have important action to the occurrence of the tumor, same, in the tumor the metastasis of the process, immune state of normal or not to metastasis occurrence of sooner or later and metastasis neoplasm growth of the rate of speed be exertive predominant action.The immune state good can repress a tumor metastasis and make the tumor long-playing stability but be placed in from limit condition, but if the machine body immune system anti- resist the ability of tumor to lower then canned appear to transfer in early days.
? Blood coagulation mechanism:The tumor occurrence metastasis has to through swollen oncocyte and afferent endothelial cell mucopeptide attach, the fibrin pack round, the formation neoplasm bolt etc. a series of process.In this process blood coagulation and anti- blood coagulation mechanism to the action of metastasis already widespread cause people’s value.The research discover that the carcinoma cell self can produce a Cu blood coagulation factor to make it be advantageous to afferent epithelium mucopeptide to attach and promote a metastasis.
The ? outside factor:It mainly is artificial influence of the factor upon the tumor.
