Comparison of efficacy and safety of different therapeutic regimens as second-line treatment for small cell lung cancer / 中国基层医药

ABSTRACT

Objective To discuss the efficacy and safety of different second-line chemotherapies in small cell lung cancer chemotherapy.Methods 170 patients with small cell lung cancer who were failure to first -line treatment were chosen,they were randomly divided into observation group and control group.The control group was given paclitaxel plus cisplatin second-line chemotherapy,the observation group used the irinotecan joint cisplatin second-line chemotherapy.The effect of the two groups was recorded.Results The effective rate of the observation group was 45.88%,which of the control group was 25.88%,the difference between the two groups was statistically significant (χ2 =7.389,P<0.05).The median survival time,total survival time,median disease-free survival time, Karnofsky score,pain score of the observation group were (10.32 ±2.41)months,(7.89 ±1.88)months,(7.54 ± 1.78)months,(83.23 ±6.89)points,(2.37 ±1.07)points,which of the control group were (7.45 ±1.03)months, (3.16 ±0.79)months,(3.89 ±0.68)months,(69.97 ±2.33)points,(4.81 ±2.13)points,the differences between the two groups were statistically significant (t =10.095,21.384,17.660,21.384,17.660,all P<0.05).In the observation group,nausea and vomiting occurred in 5 cases,thrombocytopenia in 3 cases,anemia in 1 case,leukopenia in 7 cases,hypodynamia in 12 cases.In the control group,nausea and vomiting occurred in 16 cases,thrombocytopenia in 11 cases,6 cases of anemia,leukopenia in 18 patients,hypodynamia in 26 cases,the differences between the two groups were statistically significant(χ2 =6.574,4.981,4.722,4.981,4.722,all P <0.05).Conclusion The second-line chemotherapy regimens with irinotecan used in small cell lung cancer patients can improve the treatment effect,adverse reaction mild,prolong patients'survival,it is worth popularizing in clinical.
