Summary

Chemotherapy is an important treatment strategy for gynecological malignancies, such as ovarian cancer, advanced endometrial cancer, cervical cancer. Chemotherapy-induced thrombocytopenia (CIT) is one of the most common chemotherapy-related hematologic toxicities and can increase the risk of bleeding, prolong hospital stays, increase healthcare costs, and, in severe cases, death. It can lead to a reduction in the intensity of chemotherapy doses, delay the next cycle of chemotherapy, or even termination of treatment, thereby affecting the antitumor effect and adversely affecting the long-term survival of these patients. Literature and our data show that when patients develop grade II or worse CIT, the incidence of grade II and above CIT after the next cycle of chemotherapy is 85-92%. Hetrombopag is one of the thrombopoietin receptor agonist (TPO-RA) that has been studied to explore its role in the treatment and prevention of CIT in multiple solid tumors. In order to find out the secondary prevention efficacy of CIT, it is planned to carry out this single-arm prospective study by recruiting 48 patients with gynecological malignancies with grade II CIT or above after chemotherapy, whose platelets has returned to normal after the routine clinical intervention, and then plan to have the next cycle of chemotherapy. The intervention strategy is taking hetrombopag 5mg/day within 24 hours after chemotherapy, then observe the incidence rate of grade II CIT. The endpoint of this study is to assess the effectiveness and safety of hetrombopag for preventing CIT in patients with gynaecological malignancies.
