The survival rate of ovarian cancer in advanced stages is about 30%, and about 70% of patients are in advanced stages. The main symptoms of advanced ovarian cancer include abdominal distension, abdominal pain, and abdominal enlargement, in addition to the presence of subcutaneous lymph nodes, such as lumps in the neck, breast, axilla and inguinal area. The disease may metastasize in the abdominal cavity, thoracic cavity or throughout the body, resulting in a higher chance of recurrence, poor quality of survival and a lower survival rate. After primary surgery, 70% of patients with advanced ovarian cancer may have a recurrence within 2 years, after which the next surgical or chemotherapy treatment is required. During this process, patients will gradually transition from platinum-sensitive to platinum-resistant, i.e., the recurrence interval is shortened from 18 months for the first time and 10 months for the second time to 8, 5, and 4 months for the follow-up. Eventually the patient progresses to abdominal distention, intestinal adhesions, intestinal obstruction, or pleural fluid, ascites, massive bleeding and intestinal fistula, which eventually leads to death.
