Abstract

OBJECTIVE:

To observe the effect of radiotherapy (RT) combined with Ginseng polysaccharide (GSP) injection in treating nasopharyngeal carcinoma (NPC) and its influence on immune function.

METHODS:

One hundred and thirty-one NPC patients were randomly divided into two groups, 64 cases in the RT-GSP group treated with RT-GSP and 67 in the control group treated with conventional therapy, to observe the local cancer remission rate, 1-year total survival rate, no tumor survival rate and no remote metastasis survival rate. Moreover, the changes of T-lymphocyte subsets, natural killer (NK) cell activity and lymphocyte activated killer (LAK) cell activity before and after treatment were observed.

RESULTS:

Clinical examination conducted 3 months after treatment showed that the complete remission rete in the RT-GSP group was 96.6%, and in the control group 93.3%, the complete remission rate of cervical node metastatic tumor in the two groups was 85.7% and 78.0% respectively, and the NPC CT remission rate 60.3% and 51.7% respectively. Re-examination carried out 1 year after RT treatment showed that the total survival rate in the two groups was 100% and 96.5%, no tumor survival rate 84.4% and 74.6%, and no remote metastasis survival rate was 93.8% and 88.1% respectively. The activity of NK cell and LAK cell as well as T3, T4 value in peripheral blood increased significantly in the RT-GSP group (all P < 0.05) after treatment, while in the control group, activity of NK cell and LAK cell changed insignificantly after treatment, and T3, T4 value lowered significantly (P < 0.05). No toxic-adverse reaction of GSP was found.

CONCLUSION:

GSP has certain improving immune function effect in NPC patients during RT, it could also eliminate the occurred adverse reaction to RT and the general condition of patients.
