OVARIAN CANCER

Most of the malignant ovarian tumors, radiation therapy for various effects are poor. Therefore, in the treatment of malignant ovarian tumor was not first consider radiotherapy. After laparotomy confirmed to be malignant ovarian tumor resection not all, in vitro viable X-ray irradiation. But many of ascites are not OK radiotherapy; The abdominal tumor metastasis to the effect of not limited to those within the pelvic cavity. X-ray irradiation is also used in vitro malignant ovarian tumor before and after surgery. Preoperative radiotherapy for patients with radiation therapy after the word four to six weeks should surgery again night, while radiation caused by adhesions, surgery often caused difficulties. Surgery will be in regular radiation treatment after two weeks before and after the start, such as whole body ill patients should first correct.
(1), abdominal irradiation radiation field including full pots of abdominal viscera, or by Ono divided into two to four vertical irradiation of Ono, tumor dose of 25 Gy ~ / 6 to 8 weeks. General liver, kidney tolerance were 30 Gy and 18 Gy, such as the super-dose, should shielding protection. Whole abdominal irradiation after Ono, the largest general tolerance of 30 Gy / 6 to 7 weeks. This dose is not LD50 of ovarian cancer, while Ono irradiation reaction, difficult patient tolerance. Delcios in 1963, a fully mobile strip abdominal irradiation in the treatment of ovarian cancer. Each abdominal irradiation of 10 cm, radiation field from the upward movement in the entire basin to include abdominal, each irradiation in 12 days. Tumor radiation dose of 26 to 28 Gy. The biological effects of radiation and improve the patient's response to radiotherapy.
(2), pelvic tumor irradiation dose of 40 to 60 Gy, 6 to 8 weeks to complete.
(3), plus whole abdominal pelvic irradiation Ono whole abdominal irradiation may be, or transfer surgery strip irradiation dose with the former. Pelvic organ tolerance, to improve efficacy, and pelvic irradiation dose of 20 to 30 Gy, ovarian cancer is the commonly used method.
(4), abdominal radionuclide therapy for patients early preventive treatment, and only a small residual tumor after treatment. Surgery not cut net of malignant ovarian tumor metastases can be injected with the radioactive colloid 98 or 32 P, or diluted with saline injected into the abdominal cavity to prevent cancer formation of ascites, malignant ovarian cancer has been with ascites, the catheter may produce ascites part, to be injected colloidal gold 98 or 32 P . It should be noted 98 of the radioactive colloid and 32 P for intraperitoneal injection, also caused radioactive hepatitis possible, it should be repeated in application check liver function for timely processing.

[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 organs, both in the diagnosis of ovarian cancer and governance the treatment is a major problem indeed. 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%.

The choice of ovarian cancer surgery, chemotherapy and radiotherapy. But because of its pathological type complex, qualitative, without a diagnosis and staging laparoscopy or laparotomy, it is difficult clear. In addition to surgery is not generally the case or have the type of tumor in patients with systemic conditions not competent to surgery, chemotherapy or radiotherapy to trial again after surgery to consider, as appropriate, generally the preferred treatment. Surgical exploration can be further defined tumor types and scope of involvement, clear staging, not only for postoperative chemotherapy and radiotherapy provide basis, and possible removal of the tumor, chemotherapy or postoperative radiotherapy or create conditions to improve efficacy.

Clinical manifestations

(1) a <BR> symptoms, age occurred in perimenopausal women. Over more than 35 years of epithelial ovarian cancer, while those below the age of 35 occurred reproductive cell malignancies.
2, the pain may be due to malignant ovarian tumor of the changes, such as hemorrhage, necrosis, the rapid growth caused a considerable degree of persistent pain. The inspection found a local tenderness.
3, Irregular Menstruation see irregular bleeding, bleeding after menopause.
4, weight loss was sexually advanced thin.

A benign ovarian tumors young patients affected Annex tumor resection or stripped of. If both bilateral ovarian tumors, should fight to retain part of normal ovarian tissue. Before post-clearance as abdominal specimens suspected malignant sent frozen biopsy. Patients before and after menopause to be hysterectomy and bilateral resection of the Annex to activities.

2, malignant ovarian tumor treatment to the main, supplemented by chemotherapy, and radiotherapy.

(1) to general surgery for hysterectomy, bilateral Annex and the omentum resection. Patients with advanced cancer should be possible for the transfer to that reduction of tumor cells. As for retroperitoneal lymph node removal of the therapeutic value can not be determined.

(1) genetic and familial factors. About 20% to 25% of ovarian cancer patients have family history. The so-called familial aggregation of ovarian cancer refers to a high per capita, mainly epithelial cancer, skin - women's syndrome - a 5% to 14% of ovarian cancer, and basal cell nevus syndrome often coexist with ovarian fiber.

(2) environmental factors. Industrial countries a high incidence of ovarian cancer may be related to dietary cholesterol content.

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.
