There are 5 pathological types of ovarian cancer

The incidence of ovarian cancer is second only to cervical cancer and endometrial cancer. In the past 10 years, the incidence of ovarian cancer in my country has shown a clear upward trend, with a 5-year survival rate of only 30%, and the mortality rate ranks first among gynecological tumors.

There are five main pathological types in the continuous development of ovarian cancer:

1. Ovarian malignancies originating from the embryonic epithelium, i.e., the epithelium of the paramesonephric coelomic epithelium, include common serous adenocarcinoma, mucinous adenocarcinoma, endometrioid adenocarcinoma, mixed serous mucinous cystadenocarcinoma, and less common ones include fibroadenocarcinoma, malignant Brenner's tumor, paramesonephric clear cell carcinoma, undifferentiated anaplastic carcinoma, etc. These tumors sometimes have luteinization, which may lead to the occurrence of luteinized unruptured follicle syndrome.

2. Ovarian malignant tumors originating from embryonic cells, such as teratocarcinoma, primary choriocarcinoma, dysgerminoma, etc. This type of cancer can sometimes secrete hormones, which can cause a series of changes in the patient's body.

3. Ovarian tumors originate from undifferentiated mesenchyme. Tumors differentiated from this mesenchyme can be divided into benign and malignant, but malignant tumors are the majority.

4. Some ovarian malignant tumors originate from sexually differentiated mesenchymal lobes. This type of tumor can produce autologous hormones and is also called functional tumors. They are all potential ovarian malignant tumors and are extremely harmful to the human body.

5. Ovarian malignant tumors occurring in ectopic tissues within the ovary and malignant adrenal cell remnant tumors.

Tips: What is Luteinized Unruptured Follicle Syndrome?

Luteinized unruptured follicle syndrome refers to the situation where the follicle is mature but not ruptured, the egg cell is not discharged but luteinized in situ, forming a corpus luteum and secreting progesterone, and a series of changes similar to the ovulation cycle occur in the effector organs of the body. The main characteristics of the patient are regular menstrual cycles, similar ovulation performance but persistent infertility.
