Objective To discuss the clinical value of CT-guided percutaneous embedding of 125I seeds in combined chemotherapy with TP regime for non-small cell lung cancer(NSCLC). Methods Thirty two patients with NSCLC received CT-guided percutancous embedding of 125I particles, TP chemotherapy plan (paclitaxcl 135 mg/m2 /d1, cisplatin 75 mg/m2/d2 ～ 4 ) for four cycles after operation. The follow-up CT for observing therapeutic effects at 1, 3, 6, 12 month after 125I seeds implantation was undertaken. Results All cases were controlled effectively after one month revealed by CT follow up. The efficiency of tumor curing at 3, 6, 12 month were 87.5%, 90.63%, 92.31% respectively. None of the patients showed radiation injury and particle migration, and all of them had only slight side effects. Conclusion CT-guided percutaneous embedding of 125I seeds in combination with chemotherapy for non-small cell lung cancer is an effective and safe method, possessing valuable utilization clinically.
