What are the auxiliary examinations for ovarian tumors

When it comes to ovarian tumors, I believe everyone is familiar with them. Ovarian tumors are a very common gynecological tumor, which is very common in today's society. Ovarian tumors cause great harm to patients. The cause of the disease is unknown, and the patient's early symptoms are not very obvious. Therefore, many patients miss the best treatment period for the disease. The diagnosis of ovarian tumors is very critical. I believe everyone wants to know how to diagnose ovarian tumors? So, let's take a look together.

(1) Ultrasound examination: B-ultrasound imaging can detect the location, size, shape and nature of the tumor.

(2) Radiological diagnosis: Barium meal or barium enema, air contrast radiography can be used to determine whether there is a tumor in the digestive tract. CT examination can locate and characterize pelvic tumors, and determine whether there is metastasis to the liver, lungs, and retroperitoneal lymph nodes. Pelvic lymph node radiography can determine whether ovarian tumors have lymphatic metastasis.

(3) Laparoscopy: It can directly observe the origin and general condition of the tumor, as well as the entire pelvic and abdominal cavity and diaphragm, to determine the extent and stage of the lesion. It can also aspirate ascites for cytological examination or take suspicious tissue for pathological examination. However, it is contraindicated for large masses or adhesion masses.

(4) Cytological examination: Cytological examination of ascites obtained by abdominal or posterior fornix puncture is helpful in the diagnosis of ovarian malignant tumors.

(5) Tumor marker examination: Patients with embryonal carcinoma and endodermal sinus carcinoma have high alpha-fetoprotein (aFP) concentrations, and aFP greater than 20 μg/L is considered positive. β-hCG determination has diagnostic value for primary ovarian choriocarcinoma and ovarian germ cells mixed with choriocarcinoma components. Cancer antigen CA125 radioimmunoassay (CA125 greater than 65 U/ml is considered positive) has a high diagnostic significance for epithelial cancer. Lactate dehydrogenase (LDH) determination is helpful for the diagnosis of dysgerminoma.

(6) Laparotomy: Ovarian enlargement found before puberty, and ovaries that can still be palpated after menopause; ovarian cystic tumors in women of childbearing age with a diameter greater than 6 cm that do not shrink or increase in size after 3 to 6 months of observation; solid tumors with a diameter greater than 4 cm; ovarian masses found in early pregnancy that do not shrink after 4 months of pregnancy are all indications for laparotomy.

The above is an introduction to the diagnosis of ovarian tumors. I believe that after reading the above article, everyone will have a further understanding of the diagnosis of ovarian tumors. Understanding this knowledge can help everyone find and diagnose ovarian tumors earlier in life, so that ovarian tumors can be treated earlier and the harm caused by ovarian tumors to patients can be minimized.
