Study of Gene Expression Profiling and Immunological Mechanism Affects the Response of Immunotherapy
Study of Gene Expression Profiling and Immunological Mechanism Affects the Response of Immunotherapy
To investigate gene expression profile and immunological associated analysis relating to
 immunotherapy response of patients with malignant tumor presenting malignant cavity effusion
 after DC-CIK immunotherapy.
1. The patients with malignant cavity effusion are treated with dendritic cells (DC) plus
 cytokine induced killer cells (CIK) locally.

 2. Malignant cavity effusion from cancer patients is obtained through puncture and is
 centrifugalized to get supernatant fluid and enrich cancer cells before and after the
 therapy.

 3. The enriched cancer cells which are flash frozen, as well as the supernatant, are stored
 at -80°C until processing.

 4. The T-Cell Receptor/B-Cell Receptor gene expression in cavity effusion is detected by
 micro-array to explore the mechanism that DC-CIK immunotherapy controls the malignant
 cavity effusion.

 5. Statistical analysis is performed using unsupervised hierarchical cluster.
Inclusion Criteria:

 1. Histologically confirmed with malignant tumor and malignant cavity effusion.

 2. An Eastern Cooperative Oncology Group（ECOG）performance status of 0-2.

 3. Normal cardiac, hepatic, renal and bone marrow functions.

 4. Life expectancy >3 months.

 5. Not receive other anti-tumor treatment.

 6. Not receive chemotherapy in pleural and abdominal cavity.

 Exclusion Criteria:

 1. Previous history of other malignancies.

 2. Serious or uncontrolled concurrent medical illness.
