Autologous Hematopoietic Stem Cell Transplantation

This study is a prospective, multicenter, randomized controlled clinical trial planned to enroll 64 female hematologic patients aged 14 to 50 years scheduled for autologous hematopoietic stem cell transplantation (auto-HSCT). Participants will be divided into two groups based on the use of myeloablative conditioning: the myeloablative conditioning (MAC) group and the non-MAC conditioning group. The conditioning regimen for autologous hematopoietic stem cell transplantation primarily employs melphalan. A melphalan dose \>140 mg/m² constitutes myeloablative conditioning (MAC), while a dose ≤140 mg/m² is classified as non-myeloablative conditioning. Within each group, patients were randomly assigned 1:1 to the experimental group (goserelin prophylaxis) or control group using a random number table. The experimental group received a single 3.6mg subcutaneous injection of goserelin 1-3 days prior to conditioning, in addition to the standard transplantation regimen. The control group did not receive goserelin prophylaxis. The primary endpoint was menstrual recovery rate at 6 months post-transplantation (defined as ≥3 naturally occurring menstrual cycles without intervention by menstrual-regulating drugs). Secondary endpoints included: incidence of premature ovarian insufficiency (POI); ovarian reserve function markers: anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) levels; Other reproductive parameters: ovarian and uterine volume, endometrial thickness; time to neutrophil/platelet engraftment; disease recurrence rate; transplant-related mortality; and adverse event (AE) incidence. This study aims to evaluate the efficacy of goserelin in improving ovarian function following autologous hematopoietic stem cell transplantation in hematologic malignancy patients.

The goal of this clinical trial is to learn if hetrombopag promotes platelet engraftment in neuroblastoma children undergoing autologous hematopoietic stem cell transplantation. The main question it aims to answer is: · Does drug hetrombopag promote platelet engraftment? Participants will take hetrombopag every day for 6 weeks or until platelet \> 100\*10\^9/L.

This is a single arm, open, single-center clinical study. The patients who are diagnosed with lymphoma and intend to undergo ASCT will be enrolled. The aim of this study is to investigate the efficacy and safety of the conditioning regimen using mitoxantrone hydrochloride liposome, BCNU, etoposide and cytarabine for ASCT.
