Early screening for ovarian cancer allows for about 20% of cases to be diagnosed in their early stages. Detection generally follows these procedures: 1. Routine gynecological health check-ups. 2. Visiting a hospital due to certain symptoms. 3. Ovarian cancer screening. Common methods include transvaginal ultrasound and serum CA125 testing. Additional tests include tumor marker CA125 and checks for AFP, CA19-9, and CEA. Ultrasonography (B-ultrasound) can preliminarily determine the tumor size, shape, solidity, location, and its relation to surrounding organs. CT scans and MRI can further clarify the tumor's nature and the extent of invasion into the abdominal and pelvic organs. If necessary, gastroscopy can be performed to rule out primary gastrointestinal tumors, and if economic conditions allow, a PADCT scan can also be conducted.

How many years can one live with ovarian cancer?

The survival period of ovarian cancer patients is influenced by various factors including the specific stage of the cancer, whether there is residual tumor after surgery, the size of any residual tumor, the pathological type of the cancer, the presence of high-risk factors for recurrence such as vascular tumor thrombus, neural invasion, lymph node metastasis, etc., as well as the patient's age, overall condition, the presence of severe comorbidities, and the patient's response and sensitivity to treatments like radiotherapy and chemotherapy. Survival periods vary due to differences in stages and treatment sensitivities, meaning it cannot be generalized; there is significant individual variation in survival outcomes.

Early Symptoms of Ovarian Cancer

Patients with ovarian cancer may have relatively hidden clinical symptoms in the early stages, possibly without any specific discomfort, or just mild lower abdominal bloating or pain. Symptoms tend to become more apparent only when the tumor progressively enlarges or when ascites occur, such as increased abdominal bloating and pain. Furthermore, during a physical examination, a solid or cystic-solid mass can be palpated in the pelvic area. Ascites can also lead to clinical symptoms such as nausea and vomiting. In the late stages, partial intestinal obstruction or symptoms related to pelvic compression may appear.

Symptoms of ovarian cancer brain metastasis

Patients with ovarian cancer experiencing brain metastases are relatively uncommon in clinical settings. The primary symptom of brain metastasis is intracranial hypertension, which includes severe headaches, dizziness, nausea, and vomiting, including projectile vomiting during meals — all symptoms of increased intracranial pressure. Additionally, if there is significant brain swelling, the patient may experience weakness in the limbs on the opposite side of the body, similar to symptoms of paralysis seen in stroke patients. Furthermore, if the brain metastasis leads to the formation of a brain herniation, the patient may experience symptoms such as coma.

Is chemotherapy effective after the recurrence of ovarian cancer?

After the recurrence of ovarian cancer, most patients can still benefit from chemotherapy again, as ovarian cancer itself is relatively sensitive to chemotherapy compared to other types of malignant tumors. If the recurrence occurs more than six months after the initial treatment, the same chemotherapy drugs used initially can still be chosen. However, if the recurrence happens within six months, the chemotherapy plan should include different drugs that were not used previously.

Can ovarian cancer be treated?

Ovarian cancer is certainly treatable. Its treatment methods include surgery, radiotherapy, and chemotherapy. For patients with early-stage ovarian cancer, the treatment is mainly radical surgery, followed by determining the need for additional adjuvant radiotherapy or chemotherapy based on specific pathological staging, the presence of high-risk factors for recurrence such as vascular tumor thrombus and neural invasion, and the situation of lymph node metastasis. For patients with advanced ovarian cancer, the treatment may involve debulking surgery and chemotherapy, with chemotherapy being the main treatment. Chemotherapy also needs to take into account the patient's general condition, along with local pelvic radiotherapy. These are the treatment methods for ovarian cancer, and the specific treatment plan should be selected based on staging and the patient's general condition, as well as the presence of other serious underlying diseases.
