OVARIAN CANCER

Metastatic ovarian cancer (metastatic ovarian tumors) or secondary ovarian cancer (secondary ovarian cancer) is the primary tumor of the lymphatic cells, vascular invasive ovarian or body cavity, and the original formation of similar tumors, and the two are not anatomical location relations.
It is not synonymous with Krukenberg's tumor.
In different regions, countries metastatic ovarian cancer incidence varies.
1. Ovarian cancer metastatic ovarian cancer and the original ratio:; 2002 Shoji Kamiura Osaka Japan reported cardiovascular disease and cancer treatment center from 1978 to 2002, 304 cases of malignant ovarian swelling cases, metastatic ovarian cancer and 64 patients (21.1%). [3] while China's Jiangxi Province MCH hospital oncology treated from 1972 to 1992 of 628 cases of ovarian cancer, metastatic ovarian cancer occupies 98 cases (15.6%) [4], and external information than the incidence rate of slightly different.
2. All of metastatic ovarian cancer in the proportion of the original: Webb reports from the gastrointestinal tract of metastatic ovarian cancer 47%, from 31% of the breast, reproductive tract from the 18%; Horie made in the original report gastrointestinal tract metastases accounted for 74% of primary breast in the accounting 13%; reproductive Road metastatic ovarian tumor is not included. Shoji Kamiura reported gastrointestinal origin of the equipment transfer 35% of ovarian tumors; Breast source of 14%; Reproductive tract sources accounted for 40%; The other 11%. Jiangxi MCH hospital reported 98 cases of non - reproductive tract sources of metastatic ovarian tumor, the source of gastrointestinal 63 patients (64.5%), breast sources of 7 cases (7.1%), other sources of the 28 patients (28.6%).

(1) of epithelial ovarian tumors
Most of age 30 to 60 years old. Divided into benign and malignant junction. The latter by the former number two to surface evolution. Borderline ovarian cancer tumor of 10 ~ 20%, a low-grade malignant potential, clinical course and prognosis between benign and malignant this; The biology of the slow growth, low rate of metastasis and recurrence later.

Also never menarche girls will have ovarian cancer?, Therapy should be what?

No girls have menstrual ovarian function although not perfect, but has had a tumor conditions, but fortunately occurred in children less ovarian cancer, after all, probably the only 4% of ovarian tumors. Although children and adolescents ovarian cancer incidence rate is low, but the proportion of malignant about 50%, but because they are in the growth and development period, a greater harm. In postmenopausal women with epithelial carcinoma seen different, the very young and teenage ovarian tumors seen in germ cell tumors, a higher proportion of malignant main endodermal sinus tumor, immature teratoma, Dysgerminoma, ovarian and primary choriocarcinoma. Childhood cancer is a common feature, namely, the degree of malignancy, rapid development, early diagnosis difficult.

Henan Medical University, a professor of obstetrics and gynecology buildings Qiao Yu, graduate students and others Rui - Xia Guo recent study found that in some tumor suppressor gene amplification or overexpression of ovarian cancer is the key factor. Entitled "epithelial ovarian cancer tumor mechanism and clinical application of" scientific research, recently Henan "progress of science and technology second prize."

Ovarian cancer is often thought of no obvious symptoms, especially in the early stages. But the New York researchers reported that ovarian cancer even in the early stages there may be some available for diagnosis of symptoms.

Many occurred in older women. To bloating, abdominal pain for the main symptoms, clinical manifestations in the medical ascites, tuberculosis peritonitis similar gay ovariectomized normal size, easily misdiagnosed as internal diseases.
The normal size of ovarian cancer syndrome pathology including four tumor: EPSPC, ovarian cancer, mesothelioma, metastatic adenocarcinoma. [4,5,6] EPSPC the United States must be based on the diagnosis of gynecologic tumors Group (GOG) diagnostic criteria:
Section 1: ovariectomized normal size, or increasing benign.
Section 2: ovarian lesions greater than the surface was hacked and ovarian lesions.
Section 3: microscopic examination of one of the following situations:
1) without ovarian lesions exist;
2) only tumor invasion and ovarian surface epithelium, seamless infiltration;
3) tumor invasion and ovarian surface epithelium and the cortex, but the tumor size <5mmX5mm;
4), regardless of ovarian surface infiltration within ovarian lesions were <5mmX5mm.
No. 4: Regardless of how tumor differentiation, and tissue types of cytology, with papillary serous ovarian cystadenoma similar or identical; Features and ovarian serous papillary adenocarcinoma similar to serous mainly limited degree of differentiation, with most of the sand. Normal Size the prognosis of ovarian cancer syndrome in epithelial ovarian cancer worse.

Ovarian cancer is very common, all ages can ill, but 20 to 50 years old the most. Since early ovarian cancer patients have few symptoms, so early diagnosis difficult, attendance at the 70% already advanced, little access to early treatment, five-year survival rate always hovering in the 20 ~ 30%, is the most serious threat to women's lives malignant one.
