OVARIAN CANCER

Surgery

According to a medical examination and transvaginal ultrasound findings suspected ovarian cancer is often a laparotomy to be confirmed histology, and tumor stage and tumor debulking surgery. Histological need to be certified to remove ovarian cysts Mixed other causes, including non - epithelial ovarian cancer (such as interstitial or germ cell tumors), other primary site of tumor metastasis to the ovary (such as the adhesion of), or benign lesions, such as endometriosis. The adhesion is usually of signet ring cell tumor, representatives from primary adenocarcinoma of the stomach metastatic ovarian cancer. However, other parts of the original cancer, such as colon, appendix, the gallbladder and breast (special lobular invasive carcinoma) will also transfer to ovarian. At laparotomy surgery during the stage, right after the decision-making guidance provided important information, especially for patients with early (discussed below). Finally, the tumor debulking surgery (initial cytoreductive surgery) is the first of an important part of the operation because of residual tumor with a diameter of less than 1 cm larger than the residual tumor with a high survival rate.

(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.

Ovarian cancer prevention focuses on the early detection of tumors, benign or malignant regardless of the early patients, often without obvious symptoms, benign tumors may have malignant transformation should be undertaken regularly Cape couple. For early detection of ovarian cancer, the following points should be noted:
(1) All solid ovarian mass, or more than 6 cm cyst, shall immediately proceed to surgical resection.
(2) menarche before and postmenopausal women, ovarian cystic tumor, the tumor should be considered. Women of childbearing age in a small annex cystic mass of two narrow, not to consider the tumor, increasing the period of operation at any time.
(3) pelvic inflammatory masses, especially tuberculosis or suspected pelvic endometriosis treatment of tumors block invalid, can not be ruled out cancer surgery should be explored.
(4) found that postmenopausal endometrial hyperplasia or adenoma endometrial adenocarcinoma, it should be noted whether ovarian tumors, and timely treatment.
(5) aged 45 and above, subject to the result of uterine diseases hysterectomy, the proposal for bilateral Annex.
Ovarian cancer causes complex, but in terms of prevention, at least for reference to the following points:
Not forgetting peacetime exercise: The United States aspirin-chee at the University of Pennsylvania School of Medicine study, regular exercise women, life with the opportunity to nest cancer than inactive women below 27%.
Less fat diet: normal diet contains too much saturated fat women suffering from ovarian cancer more easily. Most of the American women, daily intake of saturated fat is about 30 grams, can be a daily diet of 10 grams of fat lowering the volume, the probability of ovarian cancer can be reduced by 20%. If you are with the probability of ovarian cancer, like most people around 1% reduction of dietary fat, the probability would fall to 0.8%. Although we still do not know why there is this advantage, but a balanced diet, eat more vegetables, fruits, but for the health of the sound is definitely useful. Moreover, the reduction of dietary fat and fiber intake a lot, but will also reduce the probability of developing heart disease (the major cause of death of women), and reduce the incidence of colon cancer. Appropriate calcium benefits, according to the study: women's diets, the highest calcium diet compared to the lowest calcium intake, the opportunity to be ovarian cancer greatly reduced, high calcium for the prevention of the occurrence of ovarian cancer may have health effects.
Anti-Tiaojing hormone: a survey revealed that long-term use of birth-not pregnant women to be called LMP (low malignant potential) tumor risk will increase. Women's menstrual early (before age 12) or late menopause or a birth (or the first birth after the age of 30) in ovarian cancer risk higher. It seems that the probability of ovarian cancer in women and one in the total number of menstruation. The number of menstrual more in the risk of ovarian cancer is also higher. A nurse will also reduce breast cancer and ovarian cancer risk, because normally babies during menopause. Use of contraceptives will also reduce the risk of ovarian cancer effect.

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."

Although ovarian cancer chemotherapy drug developed considerable progress has been made, but patients with ovarian cancer and the overall survival rate has not improved markedly. Philadelphia's Fox Chase Hospital Dr. Bernard of ovarian cancer screening, treatment and prevention of, and possible future trends.

【Medical industry network Docguide.com2003 According to the January 14 Houston - the new study concluded that women with ovarian cancer can survive, the immune system T cells in which played a major role. The researchers concluded that the current through the strengthening of the body's defense mechanisms intrinsic to the efforts of a cancer support, they speculate on ovarian tumor T cells may help doctors predict the prognosis of patients, and guide treatment. The United States advanced ovarian cancer patients survive five years to less than 25%.

[Summary]
Ovarian cancer is a common cancer of female genital mutilation one of the incidence of cervical cancer and after cancer of the uterus, which ranked third. But ovarian cancer death, accounts of the first gynecologic tumors, right pose a serious threat to women's lives. Because ovarian embryonic development, organization anatomy and endocrine function more complicated, it may be suffering from benign tumors or malignant. Because of early ovarian cancer in asymptomatic, and the identification of its type benign and malignant very difficult, ovarian carcinoma laparotomy in ovarian tumor confined to only 30%, most have spread to the uterus, bilateral annex, the omentum and pelvic organ <BR>, without ovarian cancer On the diagnosis and treatment really is a big problem. Over the years experts on the pathological form of ovarian cancer, the development of clinical and treatment programs for many of accumulated a lot of experience, so far, statistics on domestic and foreign clinical data, the five-year survival rate of only 25% to 30%.

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.
