Current Issues in the Management of Patients With Newly Diagnosed Advanced-Stage High-Grade Serous Carcinoma of the Ovary - PubMed
Ovarian cancer is the most common cause of mortality in patients with gynecologic malignancies. Advanced-stage high-grade serous carcinoma accounts for most ovarian cancer cases.

Questions:

  1. What is the primary benefit of performing primary debulking surgery in patients with advanced-stage epithelial ovarian cancer before administering chemotherapy?

    • A) To eliminate the need for chemotherapy
    • B) To allow for accurate staging and histologic confirmation
    • C) To improve the effectiveness of subsequent chemotherapy by reducing tumor burden
    • D) To increase the patient's overall survival without the need for chemotherapy

  2. What is the primary mechanism of action of paclitaxel (Taxol) in the treatment of ovarian cancer?

    • A) It disrupts DNA synthesis by forming crosslinks between DNA strands
    • B) It prevents cancer cells from dividing by stabilizing microtubules
    • C) It inhibits angiogenesis, preventing tumor blood vessel formation
    • D) It enhances immune system activity against cancer cells

  3. Why is platinum-based chemotherapy, such as carboplatin, considered the standard treatment following debulking surgery for advanced ovarian cancer?

    • A) It directly attacks tumor blood vessels to reduce growth
    • B) It induces DNA damage in cancer cells, leading to apoptosis
    • C) It stimulates the immune system to fight the cancer
    • D) It prevents cancer cells from forming new blood vessels

  1. Answer: C) To improve the effectiveness of subsequent chemotherapy by reducing tumor burden

    Explanation: Debulking surgery plays a crucial role in the management of advanced epithelial ovarian cancer because it significantly reduces the tumor burden, allowing subsequent chemotherapy to be more effective. When large tumor masses are removed, the remaining cancer cells are often in a growth phase, making them more sensitive to chemotherapy. Chemotherapy targets rapidly dividing cells, so the smaller the residual tumor, the greater the proportion of cells actively growing and the more susceptible they become to treatment. This surgical approach maximizes the chance of achieving a state of minimal residual disease, which has been shown to improve overall survival and reduce the likelihood of recurrence.

  2. Answer: B) It prevents cancer cells from dividing by stabilizing microtubules

    Explanation: Paclitaxel (Taxol) works by stabilizing microtubules, preventing them from disassembling during cell division. Microtubules are essential for the separation of chromosomes during mitosis. By preventing their breakdown, paclitaxel effectively halts the process of cell division, leading to apoptosis in cancer cells. This mechanism makes it particularly effective in treating rapidly dividing cancer cells, such as those found in ovarian cancer.

  3. Answer: B) It induces DNA damage in cancer cells, leading to apoptosis

    Explanation: Platinum-based chemotherapy, such as carboplatin, is highly effective in treating ovarian cancer because it works by inducing DNA damage in cancer cells. Carboplatin forms crosslinks between DNA strands, preventing the cancer cells from replicating their DNA and dividing. As a result, the cells are unable to repair the damage and undergo apoptosis (programmed cell death). This mechanism makes platinum-based agents particularly potent against rapidly dividing ovarian cancer cells, especially following debulking surgery, where the tumor size has been reduced, and the remaining cells are more vulnerable to chemotherapy.
