Cistadenokarcinoma of the ovary: types, symptoms, causes and treatment
Cistadenokarcinoma ovarian is a malignant neoplasm that develops on the surface of the epithelium. In some cases, a malignant tumor can lead to the formation of cystic cavities on the surface of the body. This disease is extremely common, it is diagnosed in approximately 40-50% of all cases of epithelial tumors of malignant nature. Cistadenokarcinoma ovarian also called secondary cancer of internal organs.
The disease practically has no «age limits» — it is equally common in women of young age and in women older than 40-50 years. Cistadenokarcinoma requires urgent and serious treatment, as a dangerous disease can lead to very adverse consequences. It should be noted that approximately 45% of cases of malignant neoplasms in the ovary region are fatal, so treatment of this disease should not be treated carelessly.
Varieties of cystadenocarcinoma
Today there are two forms of malignant ovarian tumors – serous and mucinous.
- Serous ovarian cistadenokarcinoma – this form of the disease, also called serous ovarian cancer structure. This is the most common form of malignant ovarian tumors, which is diagnosed in approximately 60% of all cases. In the majority of cases cancer is formed due to a malignancy of the epithelium of the ovarian cysts. For serous ovarian cystadenocarcinoma phenomenon is considered to be expressed proliferation of epithelium with subsequent formation of papillary and glandular structures. The main danger of serous forms of tumors is that the tumor develops rapidly with the rapid metastasis to other organs.
- Form of mucinous tumor is a rare disease that occurs more often than 15% of all cases of all malignancies in the pelvic organs. In the majority of cases of mucinous cistadenokarcinoma takes place entirely without symptoms – the first symptoms, such as, for example, as pain in the lower part of the belly, occur at the later stages of the disease.
What symptoms may indicate the development of cancer of the ovaries?
Symptoms of ovarian cystadenocarcinoma
In most cases, this cancer can be identified by the following symptoms:
- In the early stages the swelling is virtually nonexistent – the symptoms appear only in the rarest cases and therefore, timely diagnosis of cystadenocarcinoma becomes much more complicated.
- With the progressive development of the disease in women may experience pain in the lower abdomen, which can be of different nature to be paroxysmal, sharp, aching or pulling. Especially the pain worse when you try palpation of the abdomen.
- In most cases, the tumor is accompanied by various irregularities in the activity of the gastrointestinal tract – constipation, diarrhea, flatulence, nausea and vomiting.
- Subsequently, malfunctions of the gastrointestinal tract in women may rapidly decrease body weight. Thus, simultaneously with the abrupt slimming abdomen volumes increased significantly, the body becomes disproportionate.
- At advanced stages of the disease in women there is a change in menstrual function, there may be heavy or scant bleeding from the genital tract.
- Overall health in malignant tumors is significantly worsening a woman feels constant fatigue, tiredness, lethargy or drowsiness.
The disease diagnosis method of the DRC
Timely diagnosis of malignant tumors at the earliest stages is extremely important, as it depends on the effectiveness of the treatment. For diagnosis of tumors of malignant character is by far most commonly used method of color Doppler mapping – DRC.
The DRC is an innovation in ultrasound diagnostics. The basic principle of the DRC is in the visualization and assessment of blood vessels in the tumors formed, whereby the DRC facilitates the most accurate differentiation of tumors of the pelvic organs, benign or malignant nature.
Diagnosis the DRC method is based on the velocity of blood flow in the vessels of the ovary, and tumors, the indices of resistance and ripple. During the DRC, it becomes possible to identify the vascularization of the tumor. This indicator is considered important in the DRC, as the level of vascularization in benign and malignant tumors is significantly different in their activity.
Treatment of ovarian cystadenocarcinoma
In the majority of cases for the treatment of ovarian cystadenocarcinoma applied complex methodology, consisting of operational and traditional treatment. Depending on the localization of the neoplasm in the course of surgery is removal of the uterus and diseased internal organ, in some cases, is resection of the two ovaries.
In the further treatment of cystadenocarcinoma includes chemotherapy with the regular conduct of the DRC, and, if necessary, and radiation therapy. The results of treatment depend on at what stage it was diagnosed with the disease. According to the data of medical statistics in the case of removal of a malignant tumor in the early stages of indicator five-year survival rate is more than 75-85%. At the same time, in the later stages of cystadenocarcinoma this figure is significantly reduced and does not exceed the mark of 32-35%
