By Using Adoptive Transfer of Autologous NK Cells to Prevent Recurrence of Hepatocellular Carcinoma After Curative Therapy

Phase 2

• Conditions: Hepatocellular Carcinoma
• Interventions: Biological: NK cells; Other: Curative therapy

• Registration Number: NCT02725996
• Lead Sponsor: Southwest Hospital, China

Brief Summary

To prove that the efficacy and safety of 'NK group' is superior to 'non-treatment group(Control group)' in patient undergone curative resection(RFA or operation) for hepatocellular carcinoma in China.

Detailed Description

No adjuvant therapy has been shown to extend the survival of patients with hepatocellular carcinoma receiving curative treatment.We investigated whether injections of NK cells prolongs recurrence-free survival of patients after curative therapy.

2. The carcinoma has been invaded to main portal vein or major branch hepatic vein
3. Child-Pugh score is over 6
4. Patient has serious problem with pulmonary function by sub- investigator's opinion
5. Patient who has disease history of immune deficiency
6. Diagnosed as an immune deficiency patient
7. Patient who has disease history of malignant tumor within 5 years before this clinical trial.
8. Patient who had anti-cancer medication before the clinical trial
9. Patient has serious allergic-history by sub- investigator's opinion
10. Patient has serious mental disease by sub- investigator's opinion
11. Pregnant women, nursing mother or having intention of being pregnant during the clinical test
