1 Recurrence rate of ovarian cancer after surgery

The possibility of recurrence of ovarian cancer after surgery is quite high. The recurrence of ovarian cancer mostly occurs about 3-5 years after surgery. If The recurrence rate of early-stage ovarian cancer is 19% if treatment is inappropriate, and the recurrence rate of late-stage ovarian cancer is 60%-85%.

2 Why ovarian cancer is easy to relapse

For ovarian cancer, surgery can only target the crampons that have been discovered, and cancer is a systemic disease, especially for patients with advanced ovarian cancer. Cancer cells have spread to various organs of the body. Even with surgical resection, radiotherapy and chemotherapy, it is difficult to kill all the cancer cells in the body. Therefore, the remaining cancer cells develop quickly and easily when the patient is weak and has low immunity. relapse.

3 Ways of recurrence and metastasis of ovarian cancer

Generally speaking, there are four ways of recurrence and metastasis of ovarian cancer:

1. Lymphatic metastasis: Lymphatic metastasis It is a common metastasis mode of ovarian cancer. Metastases usually occur to para-aortic lymph nodes, but may also spread along the round ligament to inguinal lymph nodes.

2. Implantation metastasis: Ovarian cancer can penetrate the capsule, intestinal tube, etc., forming a large number of nodular or papillary metastatic cancers, especially the papillary tissue of serous cystadenocarcinoma. , it is easier to penetrate the tumor capsule and spread throughout the abdominal cavity, causing a large amount of ascites.

3. Hematogenous metastasis: Except for sarcomas, malignant teratomas and advanced cases, ovarian malignant tumors rarely metastasize through blood. Generally, metastasis to distant sites can reach the liver, pleura, lungs and other sites.

4. Uterine cavity metastasis: Advanced ovarian cancer not only adheres to surrounding tissues, but also directly infiltrates these tissues, such as the uterus, parietal peritoneum, broad ligament, fallopian tube, colon and small intestine, and can even Spreads into the uterine cavity through the fallopian tube.

4 Is ovarian cancer easy to detect?

Since ovarian cancer lacks symptoms in the early stage, even if there are symptoms, they are not specific, and the role of screening is limited, so early diagnosis is difficult. 60% to 70% are in the late stage, and the curative effect of late-stage cases is poor.
