RESUMO
Objective To explore the methods of therapy in lung cancer patients with bone metastases, and evaluate the effects and side effects of Strontium-89 palliative therapy in lung cancer patients with bone metastases. Methods About 56 cases of bronchiogenic cancer patients with bone metastases who did not receive any radiotherapy, according to 1.48×10~7 Bq/person/time, using standard intravenous injection ~(89)Sr as treatment. Follow-up 6 months, assess according to the following parameters: pain and frequency of pain were given quantized value and got pain score, using T test for comparing the pain score. According to before and after treatment bone imaging showed the size of focus and change of the number, upgrade focus therapy effect. Examine (CEA) and (NSE), using T test for changes before and after treatment. Using T test for changes of LEU and platelet after treatment. Results After treatment for 6 months, for 77 % patients are alleviating pain (43/56), the pain went off of 13 patents, account for 23 percent of the total. The pain score from 7.3±3.6 before treatment decrease to 5.3±3.4 after treatment, dropping obviously. After treatment, the focus regressed in 14 cases, decreased in 5 cases, total efficiency is 34 %. Before and after treatment, CEA from (33.64±18.15)μg/L obviously decreased to (t=4.26, P<0.01) to (21.36±11.65) μg/L, NSE from (27.16±10.12) μg/L obviously decreased to (t=4.26, P<0.05) to (12.56±4.23) μg/L. After treatment, LEU and platelet decreased to the lowest, LEU decreased about 27.9 %, platelet decreased about 19.7 %, after 3 months,normal rate of blood picture is 75 %(42/56). Conclusion The method of strontium-89 palliative therapy in lung cancer patients with bone metastases is good, safe and has little side effects, it can improve the quality of patients life.
RESUMO
Objective To analyze features and diagnostic value of imageology of the early peripheral lung carcinoma.Methods The dynamic changes of early peripheral lung carcinoma confirmed pathologically in 21 cases were retrospectively analysed.The imaging features in combination with pathological data were also analysed.Results All of 21 cases,16 cases were the tubercle type(76.1%),3 cases were the spot type(14.3%) and 2 cases were the vacuole type(9.6%).Conclusion The typical imaging features of early peripheral lung carcinoma are few,the dynamic observation of the disease is of relatively high value in diagnosis.
