Clinical observation of Oxycontin combined with Gabapentin for treatment of malignant neuropathic pain / 中国综合临床

ABSTRACT

Objective To observe the effect of Oxycontin combined with Gabapentin for treatment of malignant neuropathic pain.Methods Sixty-three cases of malignant neuropathic pain in Jinshan Hospital Affiliated to Fudan University were randomly divided into group A, B and C.Patients of which were given Oxycontin, Gabapentin, Oxycontin combined with Gabapentin respectively for pain treatment.The analgesic effects, toxic reaction side effects, quality of life, and immune function were all compared in three groups.Results Compared with pretherapy, the cancer pain score (NRS), quality of life (QOL) and karnofsky performance status(KPS) scores in all groups were changed significantly after drugs therapy(F=375.852,154.612, 151.838,P＜0.05).The levels of CD3,CD4, CD4/CD8 and NK cells in all groups were higher than before therapy(F=158.935,108.145,366.973,92.090,P＜0.05).After treatment,the NRS, QOL and KPS scores in group C were 2.00± 0.86,44.80± 6.07, 84.50± 6.05, in group A were 3.35 ± 0.67,37.35 ± 5.71,74.50 ±10.99,and in group B were 4.05±0.94,35.85±5.90,72.00±8.34, and the different were significant (F =3.250,10.499,3.465,P＜0.05).The levels of CD3, CD4, CD4/CD8and NK cells in group C were (72.94 ±5.63)％,(41.52±4.19)％, 1.86±0.30, (27.57±6.86)％,in group A were (62.84±5.27)％, (33.84 ±5.40)％,1.35±0.37, (20.49±6.67) ％,and in group B were (62.22±8.10)％, (33.19±6.90)％, 1.32 ± ±0.41, (20.32±5.63) ％, and the different were significant (F =3.377,3.344,3.352,3.386, P＜ 0.05).The patient in group C had less adverse effects than those in group A and B.Conclusion Oxycontin and Gabapentin in treatment of malignant neuropathic pain is effective.
