10:15 - 18:15 | Presenting Author(s): Hiroyasu Koga
- Abstract
Background
Because of the delayed cessation of the asbestos use in industry, the malignant pleural mesothelioma patients are increasing in Japan. Simultaneously, lung cancer patients, who have history of asbestos exposure, is increasing in our hospital.
Method
We analyzed the characteristics of the lung cancer with the history of asbestos exposure. This study enrolled 1216 patients operated on in our department with a diagnosis of lung cancer since January 2003 to March 2018. Among them, 153 patients (12.6%) had the history of asbestos exposure.
Result
The patients were 145 men and 8 women, the age were 47 to 83 (mean 70) years old, shipyard workers were 22 men. 64 patients pointed out by the regular medical checkup, 61 were in the middle of detailed examination for other disease, 10 had hemoptysis, and 9 patients were suffering from cough. The affected sites were right 92, left 61.
The operative procedures were pneumonectomy 2, lobectomy 116, segmentectomy 8 and wedge resection 21. Postoperative complications were 49 episodes in total, such as bronchopleural fistula, pneumonia, ALI. 30 days mortality was 3cases (0.02%).
The histology were adenocarcinoma 87, Squamous cell carcinoma 49, adenosquamous cell carcinoma 5, small cell carcinoma 4, Large cell carcinoma 2, and LCNEC 4. The postsurgical stage (UICC ver,6, UICCver.7) were StageⅠA(33%,33%),ⅠB(29%,33%),ⅡA (7.8%,5.8%),ⅡB(9.8%,8.1%),ⅢA(3.9%,17.4%),ⅢB(5.9%,0%),Ⅳ(2.0%,1.2%), respectively. Over all 5 years survival rate was 62.1%.
Asbestos bodies count (by Smith method) were analyzed for 51 cases. The numbers were 3 to 718041 AB/g dry lung.
Conclusion
The characteristics of the lung cancer patients who have history of asbestos exposure were not unique, and no very special issues, in the aspects of symptom, histology and prognosis.
