Introduction:
Ovarian cancer is a type of cancer that affects the ovaries, which are the female reproductive organs responsible for producing eggs. It is one of the most common types of cancer affecting women worldwide.
Epidemiology:
Ovarian cancer is the eighth most common cancer in women worldwide, accounting for approximately 239,000 new cases and 152,000 deaths annually. The risk of developing ovarian cancer increases with age, with most cases diagnosed in women over 50 years.
Risk Factors:
Several risk factors have been identified for ovarian cancer, including:
- Family history: Women with a family history of ovarian or breast cancer are at increased risk.
- Genetic mutations: Mutations in the BRCA1 and BRCA2 genes increase the risk of ovarian cancer.
- Age: The risk of ovarian cancer increases with age.
- Reproductive factors: Women who have never given birth or late pregnancy
Symptoms:
The symptoms of ovarian cancer can be non-specific and may not appear until the disease is advanced. Common symptoms include:
- Abdominal pain or discomfort
- Bloating or swelling of the abdomen
- Difficulty eating or feeling full quickly
- Urinary frequency or urgency
- Fatigue or feeling weak
Diagnosis:
The diagnosis of ovarian cancer typically involves a combination of imaging tests, laboratory tests, and surgical procedures. The following tests may be used:
- Transvaginal ultrasound (TVUS): A type of ultrasound that uses a probe inserted into the vagina to examine the ovaries.
- Computed tomography (CT) scan: A type of imaging test that uses X-rays and computer technology to produce cross-sectional images of the body.
- Blood tests: To measure levels of certain proteins or hormones in the blood, such as CA-125.
Staging:
The stage of ovarian cancer is determined by the extent of the disease. The International Federation of Gynecology and Obstetrics (FIGO) staging system is commonly used:
- Stage I: The cancer is limited to the ovaries.
- Stage II: The cancer has spread to the pelvic organs.
- Stage III: The cancer has spread to the abdominal organs or lymph nodes.
- Stage IV: The cancer has spread to distant organs, such as the liver or lungs.
Treatment:
The treatment of ovarian cancer typically involves a combination of surgery, chemotherapy, and targeted therapy. The goal of treatment is to remove the cancer, alleviate symptoms, and improve quality of life.
- Surgery: The primary treatment for ovarian cancer is surgery, which involves removing the ovaries, fallopian tubes, and uterus.
- Chemotherapy: Chemotherapy is used to kill cancer cells that remain after surgery. Common chemotherapy agents used for ovarian cancer include carboplatin, paclitaxel, and topotecan.
- Targeted therapy: Targeted therapy is used to treat ovarian cancer by targeting specific molecular pathways involved in cancer growth and progression. Common targeted therapies used for ovarian cancer include bevacizumab and olaparib.
Features of Therapy:
The following are key features of therapy for ovarian cancer:
- Multidisciplinary approach: Ovarian cancer treatment involves a multidisciplinary approach, including surgery, chemotherapy, and targeted therapy.
- Personalized medicine: Treatment is tailored to the individual patient, taking into account factors such as age, overall health, and genetic mutations.
- Palliative care: Palliative care is used to alleviate symptoms and improve quality of life for patients with advanced ovarian cancer.
