how-does-cervical-cancer-is-proliferate
There are two ways for cervical cancer proliferate.
1.Cervical cancer’s main diffusion path for direct spread and lymph shift, minority menstruation loop jump. one, direct spread is the most common stretched form. The cancer lump may spread directly or follows the lymph vessel infiltration encroach upon the neighbor the organization and the organ.because the dome is shallow the 1. outward downward infiltration before the vagina dome and the vaginal wall, therefore before, the vaginal wall compares the behind to invade frequently for the morning. Sometimes the vaginal wall infiltration assumes the gap shape, the cancer cell may spread along the vagina mucous membrane under Lymphatic tissue, is leaving the cervix of the uterus to compare the distant place to present the isolated shift stove.
2.2. cancer lump to both sides spread to palace nearby and trough wall organization, because nearby the palace the organization is loose, the lymph vessel is extremely rich, once the cancer lump wears out the cervix of the uterus myo- membrane, then along palace nearby rapid proliferation, implicates the main ligament, the shinbone ligament, even trough wall organization. When the ureter receives the infiltration or the oppression create the obstruction, may cause the renal pelvis ureter water. the 3. cancer lump infringement may spread the opportunity which from the cervical canal introversion in occurs to the palace body cervical canal to be many. 4. adjacent organs’ infringement later period cervical cancer may encroach upon the urinary bladder forward, may invade and the rectum backward. Because the urinary bladder and the cervix of the uterus compare the rectum and the cervix of the uterus relations are closer, often first passes through the vagina front board infringement urinary bladder, then backward wears out the vagina rectum to separate, implicates the rectum. But infringement rectum is rare. the two, lymph shifts are cervical cancer most important shift ways. Generally is the lymph vessel shifts first along the cervix of the uterus nearby to the foramen obturatum, qia in and qia outside and so on region lymph nodes, then again shifts before qia total, the shinbone and nearby the abdomen aorta the lymph node. The later period patient may the distant place shift to the collar bone on the lymph node or the depth inguen lymph node.
The Henrikson high-ranking military officer neck cancer lymph shift divides into two big groups:①First-level group: Including the palace nearby nearby the lymph node, the cervix of the uterus (ureter) the lymph node, the foramen obturatum lymph node, qia the endolymph ties, qia Perilympha to tie with the shinbone lymph node;②Second-level group: Including qia nearby total lymph node, inguen lymph node and aorta lymph node. the lymph node shift’s formation rate do not increase along with the clinical time, but various authors reported the lymph transfer rate phase difference is very large. Domestic places reports such as Shanghai, BeijingⅠThe time lymph node transfer rate is 5.4~7.7%,ⅡThe time transfer rate is 35~42%. in 1980 the Shandong Medical college affiliated hospital and so on seven hospitals counted 1376 example cervical cancer surgery to excise the specimen inspecting office to see, I issue of 74/638 example, the lymph node transfer rate was 11.6%,ⅡThe time 237/711 example, the lymph node transfer rate is 33.3%. The overseas some person of comprehensive surgeries and leave one’s body behind with one’s soul becoming an immortal the material, various issue of lymph transfer rate is:ⅠThe time (104/645), accounts for 16%;ⅡThe time (87/282), accounts for 31%;ⅢThe time (61/101), accounts for 60%;ⅣThe time (12/16), accounts for 75%.
Clinical and the pathology confirmed that some cases are also very early namely present the lymph node shift, but another some cases are very late do not have the pelvic cavity lymph shift, this kind of difference is possible and lymph’s immunity function concerns. Shandong Medical college pathology department once after 462 example cervical cancer technique survives 5 year above pelvic cavity lymph node to carry on under the mirror the shape observation, discovered that the lymphocyte superiority transfer rate is 10.72%, the germinal center superiority transfer rate is 35.9%, the lymphocyte reduces the transfer rate is 28.21%.
