Patients with IC stage of ovarian hyperdifferentiated mucinous adenocarcinoma are preferred to be treated by radical surgery after excluding contraindications to surgery, and 3~6 cycles of adjuvant chemotherapy are needed after surgery. IC stage of ovarian highly differentiated mucinous adenocarcinoma belongs to relatively early stage, the scope of cancer lesions is relatively limited, and high differentiation indicates that the morphology of tumor cells does not differ much from that of normal cells, and the degree of malignancy is on the low side. If there are no contraindications to surgery, radical surgical resection of ovarian cancer combined with regional lymph node dissection is usually given first. In order to reduce the risk of local recurrence and distant metastasis after surgery, it is usually necessary to give 3-6 cycles of chemotherapy, which is a combination chemotherapy program containing platinum drugs, and platinum drugs are often chosen as carboplatin, cisplatin or oxaliplatin. Once diagnosed, patients with IC stage of highly differentiated mucinous adenocarcinoma of the ovary should consult the hospital as early as possible and be given standardized treatment by professional doctors.
