Objective To investigate the effect of two chemotherapeutic regimens suitable for elderly ad -vanced non-small cell lung cancer(NSCLC).Methods A total of 58 elderly advance nonsmall cell lung cancer pa-tients randomized into two group:single-agent group and combined group .Single-agent group received gemcitabine 1 000mg/m2 at Days 1 and 8 for a 21 day cycle.Combined group received gemcitabine 1 000mg/m2 at Days 1 and 8 in combination earboplatin AUC 5 at Day 2 for a 21 day cycle .All patients in the two groups received 3 cycles of chemotherapeutic regimens.Results Of the single-agent group,complete remission (CR) in 1 cases,partial remis-sion (PR) in 12 cases, the effective rate was 46.4%,and of the combined group,CR in 1 cases,PR in 13 cases,the effective rate was 50.0%,there was no statistically significant difference between the two groups (P>0.05).Of the single-agent group,the median survival time was 9.7 months,1-and 2-year survival rates were 31.3%,12.5%,re-spectively,and of the combined group ,the median survival time was 10.1 months,1-and 2-year survival rates were 33.8%,15.6%,respectively,there were no statistically significant difference between the two groups (χ2 =1.743, 1.529,1.739,all P>0.05).The leutropenia and thrombocytopenia incidence of 3 to 4 grade in the combined group was 50.0%,46.4%,respectively,which were significantly higher than 28.6%and 18.0%in the single-agent group (χ2 =4.41,4.69,all P<0.05).Lung Cancer Symptom Scale scores showed:after the treatment,the anorexia,fatigue and pain scores of the single-agent group improved significantly compared with pre-treatment ( t =2.687,2.789, 2.603,all P<0.05),whereas no significant improvement in the combined group;After the treatment,three symptom scores of the single-agent group were significantly higher than those of the combined group (t=2.986,3.569,2.764, all P<0.05).Conclusion Single-agent gemeitabine regimen efficacy is comparable with that of combined regimen for elderly advanced NSCLC with less adverse effects .

Objective To evaluate the acute side effects and efficacy of three dimensional conformal radiotherapy(3DCRT)combined with chemotherapy(CT)for locally advance non-small cell lung cancer(NSCLC).Methods from May.2002 tO Dec 2004,36 patients with NSCLC were treated with three dimensional-conformal radiotherapy combined with chemotherapy navelbine+cisplafin(NP)Results The overall response rate(CR+PR)was 91.7% for the primary tumor,and 100%for metastases mediastinal lymph mode.The leucopenia mte was 94.4%(55.6%Grade 3.4)Acute radiation esophagitis occurred in 52.8%of patients(Grade 1.2)Acute radiation pneumonitis was observed in 11.1%of patients(Grade 1.2)Conclusion 3DCRT combined with CT is well tolerated in most patients with NSCLC.Its early responses are milder than the conventional radiotherapy combined with chemotherapy.Remote results awmt further follow-up

Objective To investigate the effects of low-dose X-ray radiation on pituitary gland area to treat benign prostatic hyperplasia.Methods Using the linear-accelerator 6mV X-ray to radiation on pituitary gland area,1.2Gy/f,2 times/week,total dose was 4.8～6.0Gy.The uro-flow rate and residual urine volume were measured.Results The immediate effect was 77.5%,the 1-year effect rate was 70%.After treatment,the uro-flow rate was significantly increased(P
