ABSTRACT
Objective To discuss the value of dual-input perfusion of 320 row CT on the efficacy evaluation of small cell lung cancer (SCLC).Methods A total of 18 patients with SCLC confirmed by pathology who received cisplatin plus etoposide chemotherapy between June 2016 and June 2018 in the 8th Medical Center of Chinese PLA General Hospital were collected.All patients received 320 row CT perfusion scan at 3 time points before chemotherapy,after 2 cycles and 4 cycles of chemotherapy.Tumor size,perfusion pseudo color map and bronchial arterial blood flow (BF),pulmonary flow (PF) and perfusion index (PI) were obtained.The efficacy and adverse reactions were evaluated.The single factor analysis was used to make the group comparison.Pearson test was used to make correlation analysis.Results Two patients after 2 cycles of chemotherapy had complete remission (CR),another 2 patients after 4 cycles of chemotherapy had CR,and 3 patients of the above 4 cases with CR had abundant BF;after 4 cycles of chemotherapy,7 cases had partial remission (PR),6 cases had stable disease (SD),1 patient had progression of disease (PD).Dual-input perfusion of 320 row CT showed that 10 cases had the tumor area < 15 cm2 and 8 cased had the tumor area >15 cm2 before the treatment.There was a negative correlation between PI and the tumor area (r =-0.694,P =0.026) on patients with the tumor area < 15 cm2 before the treatment,and no correlation was found in patients with tumor area >15 cm2 (P > 0.05).One case had Ⅳ degree of bone marrow suppression,and obvious adverse reactions were not seen in the rest of the patients.Conclusion Dual-input perfusion of 320 row CT based on the simple imaging can make an accurate quantitative judgement of the effect of SCLC according to perfusion parameter,which provides a new basis for curative effect evaluation on SCLC.
