Abstract:
Objective:To explore the clinical value of endoscopic interventional therapy for locally recurrent primary lung adenoid cystic carcinoma (ACC).
Methods:The clinical data of 42 patients with locally recurrent ACC were retrospectively analyzed, and the differences of tracheal and bronchial diameter, airway scoring grade and airway obstruction degree before and after treatment were compared among three treatment methods: bronchoscopic interventional therapy + palliative radiotherapy, interventional therapy alone, and non-interventional therapy. Log rank test and Cox proportional risk model multi-factor analysis were used to determine the prognostic factors of ACC patients with local recurrence, and the long-term effect of bronchoscopic interventional therapy on ACC with local recurrence was determined.
Results:The median overall survival of 42 patients was 59 months and 5-year survival rate was 54.2%.Univariate analysis showed that vascularized cancer, pleural invasion, pulmonary atelectasis, incisal margin, microscopic classification, tumor diameter, initial TNM stage, ki-67 index, and treatment after local recurrence were associated with long-term survival of ACC patients with local recurrence (all P<0.05). Cox multivariate regression analysis showed that margin status (RR=0.272, P=0.011), tumor diameter (RR=2.586, P=0.005), initial TNM staging (RR=0.369, P=0.035), ki-67 index (RR=3.569, P<0.001), and treatment methods after local recurrence (RR=0.126, P<0.001) were independent factors influencing the prognosis of ACC patients with local recurrence. After three months of treatment, the tracheal bronchus diameters, rating of shortness of breath, and degree of airway obstruction were all improved significantly (all P<0.05), both in the interventional therapy + palliative radiotherapy group [(14.5±2.8 mm, 0.86±0.45, (14.50±10.67)%, respectively], and the interventional therapy alone group [(13.7±2.3) mm, 0.97±0.25, (15.38±12.02)%, respectively]. Meanwhile, the difference before and after non-interventional therapy was not statistically significant (all P>0.05). 5-year overall survival rates were 55.8%, 46.6% and 42.6% for patients undergoing interventional therapy+ palliative radiotherapy, interventional therapy alone, and non-interventional therapy after recurrence, with statistically significant differences (P=0.015). Patients underwent bronchial endoscopic interventional therapy and palliative radiotherapy had the best efficacy of treatment.
Conclusion:Endoscopic interventional therapy plus palliative radiotherapy is an effective local palliative treatment for locally recurrent ACC patients, which can rapidly relieve airway stenosis, improve the quality of life of patients and prolong the survival time of patients.
