Detailed Description
Malignant pleural effusion is a common complication of malignant tumor, which usually indicates that the patient has reached the advanced stage, and about 30-40% of the patients are stubborn and refractory cases. The lack of standard therapeutic drugs and protocols in clinical practice seriously affects the anti-tumor treatment effect, quality of life and survival time of patients, and the prognosis is poor. IFN-γ can significantly induce the high expression of the costimulatory molecule ICAM-1 on tumor cells, thereby enhancing the killing of TUMOR cells by T cells. Moreover, IFN-γ can enhance the activity of CAR T cells in the presence of PD-L1-PD-1 pathway, and significantly improve the therapeutic effect of T cells on solid tumors. IFN-γ is an approved clinical treatment with known side effects and well-established symptomatic treatment. Although CIK is not a clinically approved drug, it has been used on a large scale in China with good safety and has entered the medical insurance of some provinces and cities. Tcm is an improved CIK cell and has good safety. Many clinical studies have been carried out, and no serious toxic and side effects have been observed.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: IFN- Y combined with T cells First, IFN-γ was combined with CIK cells. After three failed treatments, the CIK cells were replaced with T cells. After three failed treatments, CART cells were finally replaced. |
Drug: IFN-γ and CIK cells, Tcm cells or CAR T cells
A 50ng/ mL IFN-γ solution was prepared, and the required volume of IFN-γ solution was calculated according to the final concentration of 5ng/ mL according to the volume of pleural fluid or ascites of the patient. CIK cells were injected 1.0-2.0×109 on the second day and review three days later.T cells and CAR T cells were selected sequentially according to the re-examination of pleural fluid or ascites.

Outcome Measures
Primary Outcome Measures
- Overall survival [From the time of diagnosis of tumor to death from any cause，From initiation of study treatment until date of death from any cause, up to 100 months]
The last follow-up time of the lost patient; Patients who were still alive at the end of the study were at the end of follow-up
- Progression-free survival [From time of treatment to time of disease progression or death from any cause as assessed by the investigator at each treatment period]
From time of treatment to time of disease progression or death
Secondary Outcome Measures
- Disease control rate [The tumor shrinks or stabilizes for a certain period of time，Lasts at least 4 weeks]
Proportion of patients who had a best response rating of complete response, partial response, or stable disease
- Objective response rate [8 weeks]
Total response and partial response ratio
- Molecular markers for efficacy prediction [8 weeks]
