Abstract
Objective
To investigate the clinical effects of the application of double points cryoablation through percutaneous puncture for advanced lung cancer patients.
Methods
Forty-one patients diagnosed with stage III–IV pulmonary carcinoma were selected for the study. The patients were found to have from 1 to 3 foci of carcinoma, and in each case the disease was limited to one lung. The study patients were divided randomly into 3 groups. There were 16 cases receiving routine chemotherapy and radiotherapy in group I, 13 cases treated with cryoablation at a single point in group II, and 12 cases treated with cryoablation at 2 points simultaneously in group III. The patients in the 2 cryoablation groups also received the same treatment as the patients did in group I. The clinical effects were evaluated within 6 months after treatment, and the survival rate was followed-up for 3 years.
Results
The clinical effects were improved significantly after treatment in group II and in group III compared with those in group I (P < 0.05), including an enhanced regressive rate of 21%, postponed tumor progression of 50.58% and a clinical benefit rate of 92%. The effective rate of regression in group III was higher than that in group II, 43.59% (P < 0.05), and the 3-year survival rate was 37.25%. Significant differences in side effects were not found between the 2 cryoablation groups.
Conclusion
Cryosurgery ablation at 2 points, simultaneously, and directed at 1 foci might improve the effects of treatment and the prognosis of lung cancer patients, when used in combination with routine treatment.
