Abstract

|
|
Eighteen patients with thymoma have undergone surgical treatment at Pusan National university Hospital from 1983 to 1993. The mean age of the patients was 47.3*13.3 years old and male to female ratio was 1.6:1. Eleven of the patients(61.1%) with
thymoma
had myasthenia gravis; 12 cases (66.7%) were encapsulated and 6(33.3%) invasive. Operation was complete resection in 14(77.8%) of the patients, partial resection with residual tumor in 3(16.7%), and simple biopsy in one(5.5%).
Adjuvant radiotherapy was administered in 5 of 6 invasive thymoma. Postoperatively one patient died for excessive bleeding and sepsis. A tumor relapse was observed in one patient who had invasive thymoma and underwent partial resection followed
by
postoperative radiotherapy. The overall 5-year survival rate was 88.2*7.9%. The presence of myasthenia gravis is not considered as an adverse factor in survival but it contributes to early discovery of associated thymoma. (Korean J Thoracic
