Stage 1c ovarian cancer is a relatively early stage ovarian cancer, for most patients, it can survive for 5 years or even more, and some of them can be cured. Therefore, most stage 1c ovarian cancer will not die after a few years. stage 1c ovarian cancer requires postoperative adjuvant chemotherapy after surgical resection, which can improve the 5-year survival rate of patients. Some stage 1c ovarian cancer is also more prone to recurrence and metastasis after surgery, for example, if it is hypofractionated or clear cell carcinoma, malignant tumor is found in the peritoneal fluid, or ovarian tumor ruptures before surgery, if these factors are present, the chance of recurrence and metastasis after stage 1c ovarian cancer is higher. Therefore, close postoperative review is needed to detect tumor recurrence as early as possible and to treat it as early as possible.
