Brief summary
The goal of this clinical study is to evaluate the safety of cytokine-induced-killer (CIK) cells during early transplant period of autologous hematopoietic stem cell transplant. The main questions it aims to answer are: * What adverse events occur within 2 years following CIK infusion? * Does viral reactivation (CMV, EBV, BKV) occur and lead to infection during the early transplant period of autologous hematopoietic stem cell transplant after CIK infusion? Patients will: * Receive a single infusion of CIK at a dose of 1x10\^9 to 1x10\^10 cells either intravenously or using a central venous catheter within 14±4 days after receiving the autologous hematopoietic stem cell transplantation. * Attend follow-up visits at the clinic for 24 months after the infusion.
Interventions
Derived from the patient (autologous) prior to autologous hematopoietic stem cell transplantation and administered intravenously as fresh cells at a dose of 1x10\^9 to 1x10\^10 cells over 30 minutes.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Adverse Event Assessment | From the baseline visit through 24 months after treatment initiation. | Adverse events, including any unintended signs, symptoms, or newly developed or worsened diseases, occurring after CIK infusion are tracked for 2 years after the treatment initiation. |
| 2-Year Progression-Free Survival (PFS) Ratio | From the screening visit through 24 months after treatment initiation. | * Progression-free survival (PFS) time is defined as the period from the date of autologous hematopoietic transplantation to the date of event. * An event is defined as disease progression or death due to any cause. * The censoring date is defined as the last date on which it was confirmed that no event had occurred. In cases of loss to follow-up, the censoring date is set as the last date on which the patient was confirmed to be alive. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| 2-Year Overall Survival (OS) Ratio | From the screening visit through 24 months after treatment initiation. | * Overall survival (OS) time is defined as the period from the date of autologous hematopoietic transplantation to the date of event. * An event is defined as death due to any cause. * The censoring date is defined as the last date on which it was confirmed that no event had occurred. In cases of loss to follow-up, the censoring date is set as the last date on which the patient was confirmed to be alive. |
| Immunological Assessment and Immune Reconstitution | From the screening visit through 24 months after treatment initiation. | T cell reconstitution before and after the CIK infusion is assessed using flow cytometry and cytokine expression assays. |
| Viral Reconstitution | From the screening visit through 24 months after treatment initiation. | CMV, EBV, and BKV reactivation, along with infection-related complications, are assessed to evaluate the safety and efficacy of the CIK cells. |
