Ovarian cancer
Is ovarian cancer hereditary?
The onset of ovarian cancer may be somewhat related to family history or genetic factors. Therefore, patients with a family history of ovarian cancer may have a higher risk of developing the disease compared to the general population. However, this doesn't mean that a patient with ovarian cancer will definitely pass the condition to their offspring; it merely indicates a certain level of heredity. Furthermore, for those with a family history of breast cancer, colon cancer, and endometrial cancer, it is crucial for their descendants to undergo enhanced screenings for ovarian cancer and these diseases, as their risk of developing these conditions may be higher than that of the average person.
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.
early symptoms of ovarian cancer
The early symptoms of ovarian cancer in patients are often not very obvious, so they are not easily noticed. The more common symptom is an abdominal mass, meaning you can feel a lump in the abdomen. In its early stages, the abdominal mass is not large and is not easily detectable. Most patients only discover it during gynecological examinations. As the disease progresses, the mass grows larger and the abdomen visibly expands, leading to symptoms like abdominal pain, bloating, or lower abdominal discomfort. Another symptom is ascites, which is a more common sign in patients with advanced ovarian cancer.
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.
Location of abdominal pain in ovarian cancer
Ovarian cancer in patients manifests as tumors in either both ovaries or one ovary. Therefore, the abdominal pain they experience is lower abdominal pain, not bloating or sudden, noticeable increase in abdominal size. Additionally, the primary pathway for the metastasis of ovarian cancer is through implantation, allowing widespread metastatic implants in the pelvic and abdominal cavities. There is also local spread of the tumor to the uterus, fallopian tubes, and surrounding pelvic tissues. Thus, the location of abdominal pain in ovarian cancer is in the lower abdomen, specifically pain and bloating in the pelvic area.
ovarian cancer specific drug
Ovarian cancer does not have any specific cure-all treatment. Most ovarian cancers are epithelial ovarian cancers, and there is also ovarian cancer resulting from malignant germ cells, which is a rarer pathology type. For epithelial ovarian cancer, treatment methods include surgery, radiation therapy, chemotherapy, and some targeted therapies, mainly using Bevacizumab, which is a monoclonal antibody that inhibits angiogenesis, and is usually used in combination with chemotherapy drugs. For patients with advanced ovarian cancer, those who are resistant to chemotherapy, or those in poor general health unable to endure chemotherapy, palliative treatments like hormone treatment using progestogens are an option, along with immune therapy being available nowadays. Surgery is primarily for early-stage ovarian cancer patients, where curative surgical resection is possible, or for debulking surgery in patients with advanced ovarian cancer. Chemotherapy is frequently used as it is relatively effective for epithelial ovarian cancer, a type of cancer that is somewhat sensitive to such treatments. The drugs used mainly include taxane combined with platinum-based chemotherapy. For intravenous administration or intraperitoneal delivery—for the latter, mainly for ovarian cancers complicated by extensive ascites—, positioning an abdominal drainage tube and then infusing platinum-based chemotherapy drugs into the abdominal cavity are utilized.
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.
Can ovarian cancer be cured?
Whether ovarian cancer can be cured depends on the clinical stage of the patient, as well as the patient's sensitivity to treatment, among other factors. If it is a case of early-stage ovarian cancer, curative surgery can be performed. After surgery, based on the pathology, it can be decided whether postoperative adjuvant radiotherapy or chemotherapy is necessary. Patients with early-stage ovarian cancer who undergo surgery or postoperative adjuvant radiotherapy and chemotherapy may have hope for a cure. However, if the cancer is discovered at a late stage where it has spread extensively, such as widespread metastasis to the pelvic area, or even to distant organs like the lungs or liver, then the treatment for these patients is primarily chemotherapy. A cure is not achievable; the treatment aims to alleviate symptoms and prolong the patient's life. Thus, for patients with late-stage ovarian cancer, treatment cannot achieve a curative purpose.
How is ovarian cancer diagnosed?
Ultrasound or CT scans detecting ovarian masses, in combination with biopsy or cytological examination that identify cancer cells, can diagnose ovarian cancer. A common method of biopsy includes ultrasound-guided procedures or transvaginal cul-de-sac puncture biopsy of ovarian masses, enabling clear pathological confirmation. Additionally, exploratory laparotomy or early radical surgery for ovarian cancer patients can yield a postoperative pathological diagnosis of ovarian cancer. Moreover, the presence of ascites is a common symptom in ovarian cancer patients; finding cancer cells, especially adenocarcinoma, in ascites, coupled with significantly elevated tumor marker CA125, or ultrasound or CT imagery revealing ovarian masses, can also diagnose ovarian cancer.
Ovarian Cancer Screening Methods
The methods for diagnosing ovarian cancer include imaging studies, such as ultrasonography of the adnexa of the uterus, abdominal CT, or MRI, which can detect ovarian tumors. The next step is to perform a blood test for the tumor marker CA125, which is a relatively specific and sensitive marker for epithelial ovarian cancer; in clinical practice, CA125 levels are generally significantly elevated in patients with ovarian cancer. Additionally, many patients with ovarian cancer, especially those in advanced stages, often develop significant ascites. We can perform abdominal paracentesis to drain the fluid and test the ascites for cancer cells. If cancer cells are found in the ascites and imaging studies reveal an ovarian mass, ovarian cancer can be diagnosed. Furthermore, chest CT and other tests are included to comprehensively assess the staging of the patient.
