[Lung transplantation for phase Ⅲ silicosis: a series of 32 cases].

Abstract

Objective: To evaluate the effect of lung transplantation for phase Ⅲ silicosis. Methods: From September 2002 to September 2015, 32 patients with end-stage silicosis underwent lung transplantation at Department of Thoracic Surgery, Affiliated Wuxi People's Hospital, Nanjing Medical University. There were 29 male and 3 female patients aged from 24 to 63 years. Thirty-two patients were diagnosed as phase Ⅲ silicosis by the local occupational disease prevention and control center. Fifteen patients were type Ⅰ respiratory failure and 17 patients were type Ⅱ. There were 14 cases accepted bilateral sequential lung transplantation and 18 cases accepted single lung transplantation, including 13 cases with right single lung transplantation and 5 cases with left single lung transplantation. Extracorporeal membrane oxygenation was used in 13 patients. Pulmonary function monitoring was performed at 3 months, 6 months, 1 year, and 2 years after lung transplantation. Clinical characteristics were compared using t-test, χ2 test and Fisher exact test between groups, Kaplan-Meier survival curve and Log-rank test were used to find out the factors affecting survival. Results: All the patients received lung transplantation successfully. One patient died of multiple organ failure, 1 died of sepsis, and 1 succumbed to sudden cardiac death. Twenty-nine patients were discharged from hospital. During follow-up, there were 5 deaths, two patients died of sepsis 7 months postoperatively, 1 died of renal failure 5 months post-transplant, 1 died of sudden cardiac death, and the remaining 1 patient died of bronchiolitis obliterans. Twenty-four patients lived a good quality of life, with survival rates of 90.6% at 3 months, 80.8% at 1 year, 76.7% at 3 years, and 76.7% at 5 years. Significant difference was not observed between single and bilateral lung transplantation about long-term survival rate. During follow-up pulmonary function post-transplant (3 months, 6 months, 1 year, and 2 years) were improved dramatically compared with preoperative level, and patients lived a good quality of life. Conclusion: Lung transplantation is beneficial for patients with phase Ⅲ silicosis, long-term survival is probable.
