The application effect of percutaneous cryoablation for the stage IIIB/IV advanced non-small-cell lung cancer after the failure of chemoradiotherapy.
Asian Journal of Surgery 2018 March 31
BACKGROUND/OBJECTIVE: A retrospective review is required to assess the application effect of percutaneous cryoablation on the stage IIIB/IV advanced non-small-cell lung cancer (NSCLC) after the failure of chemoradiotherapy. A total of twenty-two cases with stage IIIB/IV advanced NSCLC after failure of chemoradiotherapy were enrolled.
METHODS: Computed Tomography (CT) was used for the assessment of tumor response, and Functional Assessment of Cancer Therapy-General (FACT-G) was applied for the evaluation of quality of life. After the treatment of cryoablation, we performed a follow-up analysis.
RESULTS: The primary technique effectiveness of 100% was observed in the one month of follow-up. At three months, local tumor progression was shown in 4 of 31 lesions (13.6%). The one-year survival rate of 81.8% and progression-free rate of 27.8% were obtained. Six patients died 7, 9, 10, 12, 15 and 22 months after treatment, respectively. Decreased scores of total quality of life at one week after cryoablation (P = 0.006), but increased scores at one month after cryoablation (P = 0.024) were observed, compared with pre-cryoablation.
CONCLUSION: Cryoablation contributes to the effective local tumor therapy for stage IIIB/IV advanced NSCLC after the failure of chemoradiotherapy.
