Elemene Liposomes in Endometrial Cancer

The goal of this clinical trial is to learn if Elemene Liposomes, combined with carboplatin and paclitaxel (TC) chemotherapy can improve prognosis in patients with advanced or recurrent endometrial cancer. The main question it aims to answer is: Does adding Elemene Liposomes to TC chemotherapy can delay disease recurrence time in patients with advanced or recurrent endometrial carcinoma. Researchers will compare Elemene Liposomes +TC chemotherapy to TC chemotherapy alone to see if Elemene Liposomes, combined with carboplatin and paclitaxel (TC) chemotherapy can improve prognosis in patients with advanced or recurrent endometrial cancer. Participants will: * Receive TC Chemotherapy every 21 days, for a total of 6 cycles. * Take intravenous infusion of Elemene liposome injection every day from day 1 to day 7 of cycle 1 and 2, and take oral Elemene emulsion twice every day, from day 1 to day 14 of cycles 3 to cycle 6. (no intravenous or oral Elemene will be given in comparison group) * Visit the clinic for checkups and tests once every 21 days during treatment and every 3 to 12 months after the treatment is completed.
