Survival rates were previously cervical cancer in women so poor. In fact, was this type of cancer the most common cause of cancer death in women before, a long time. The mortality rate by 50% due to the widespread use of Pap smear but declined in the last 30 years.
In 2004, there were about 10,500 new cases of invasive cervical cancer and more than 50,000 cases of carcinoma in situ. Were 3.900 reported death from the disease, but about 85% of them were due to the lack of preventive and Detective methods such as Pap smears.
Pap smear has an accuracy of almost 90 to 95% in the diagnosis of early lesions such as CIN. The only downside is that it lacks the diagnostic sensitivity to detect cancer, if the tumor or mass is thoroughly penetrated with fungus. Inflammation, necrosis and hemorrhage may give false positive smears, and a proper biopsy may be used to confirm the existence of cancer. The American Cancer Society recommends that women, the life, an active sex life or those who already consecutive years be subject at the age of 20 annual spots for two. If they are negative, the smear should be repeated every three years. Seconded, this is also American College of obstetrics and Gynecology.
Cervical cancer survival rates by stage
Stage 0 is what they call, carcinoma in situ during phase I has a tumour which is limited to the cervix. Stage II indicates that the invasion has also gone the cervix, but not the wall of the basin and the lower third of the vagina achieved. Phase III is a tumor, which invades the wall of the basin or the lower third of the vagina or cause hydronephrosis of the bladder or rectum during finally phase IV by the invasion of the mucous membrane or an extension of the true pelvis manifested.
Cervical cancer survival rates in five years are reported as follows: level I: 85%; Level II: 60%; Phase III: 33%; and IV: 7%.
Carcinoma in situ (level 0) can be successfully treated by excision of a cone of tissue or abdominal hysterectomy. In phase I are comparable to the results apparently with radical hysterectomy and radiation therapy. Patients in phase II to IV are primarily treated with radical radiotherapy or combined modality treatment. Retroperitoneal Lymphadenectomy has no proven therapeutic value. Pelvic evisceration, is rarely, performed to treat cancer, the constant or recurring centrally to create. After that intervention can the vagina often, to reconstruct the bladder and rectum.
In women with locally advanced stage (phase II, part B of the IVA) survival rates are improved cervical cancer by administration of platinum-based chemotherapy with radiotherapy when compared to treatment with radiation alone.
