Re-chemotherapy after recurrence of ovarian cancer is useful. Re-chemotherapy after recurrence of ovarian cancer can prolong the life time of patients and improve their quality of life. It is recommended to choose platinum-containing chemotherapeutic drugs for chemotherapy after ovarian cancer recurrence, which has relatively more ideal effect. The first part of ovarian cancer to metastasize after recurrence is often the pelvis or abdominal cavity, which can easily lead to fluid accumulation in the pelvis or abdominal cavity after recurrence, and chemotherapy can significantly improve the phenomenon of fluid accumulation in the abdominal and pelvic cavity. Once ovarian cancer patients are diagnosed with recurrence, they need to undergo chemotherapy as soon as possible according to medical advice. The treatment of ovarian cancer patients is mainly based on chemotherapy and radiotherapy, through which the cancer will be made smaller and then the tumor will be removed by surgery. The treatment plan for ovarian cancer after recurrence is the same as that of ovarian cancer, which is also based on chemotherapy.
