Detailed Description
To investigate the efficacy and safety of hetrombopag for secondary prevention of thrombocytopenia in patients with lymphoma treated with XPO-1 inhibitor Selinexor combined with chemotherapy.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Hetrombopag Hetrombopag 5mg/d |
Drug: Hetrombopag
After screening, patients who were treated with XPO-1 inhibitor Selinexor combined with chemotherapy and developed chemotherapy-related thrombocytopenia (CIT) after treatment and met the secondary prevention criteria were eligible for inclusion criteria.
The platelet reduction after the previous chemotherapy was used as the control group:
The patients did not routinely receive prophylactic platelet elevation therapy after the previous Selinexor combined chemotherapy, and when PLT < 50×109/L.
Platelet reduction after chemotherapy in secondary prevention unit was used as the experimental group:
The subjects will initiate treatment with 5 mg hetrombopag once a day, starting orally 5 days before chemotherapy, take it for 5 days (D-5-D-1), and continue taking it orally for 5 days after chemotherapy (D1-D5).
