Abstract

Eighteen patients operated on for thymoma from 1985 to 1994 were evaluated, 3 with myasthenia gravis and 15 without. Masaoka's clinical staging revealed stage I disease in 5(27.8%), stage ll in 6 (33.3%), stage 111 in 6(33.3%), and stage IV in 1 (5.6%). Of the 18 patients, 10 had surgical resection as the only treatment and the remaining 8 (stage II : 1 patient, stage III : 6 patients, stage IV: 1 patient) had surgical resection with adjuvant preoperative or postoperative radiotherapy and/or chemotherapy There was no operative mortality. Currently, 15 patients are alive, 3 are dead. The mean follow up time for all patients was 3.4 years. Acturlal survival at 5 years was 82.2 $\pm$ 9% for all patients' 100% for those in stage I and II, and 62.5% for those in stage III. Pleural and mediastinal recurrence developed in one patient in stage II which was considered to have noninvasive disease on the operating field. Two patients underwent reoperation for recurrence of thymoma a intervals of 14 months and 52 months. Clinical stage and resectability had a significant prognostic value(p < 0.05). The presence of myasthenia gravis is no longer considered as an adverse factor in survival.

1985년 부터 1994년까지 18명의 흉선종 환자를 수술치료 하였다. 15명의 환자는 중증근무력증이 없었으며 3명의 환자는 중증근무력증을 호소하였다. Masaoka' 분류에 의한 임상적 병기는 I기 5 명(27.8%), ll기 6명(33.3%), 111기 6명(33.3%), IV기 1명(5.6%)이였다. 18명의 흉선종 환자중 10명 (I기 환자 5명, ll기 환자 5명)은 외과적 치료만을 시행하였으며, 8명(ll기환자 1명, 111기 환자 6명, IV 기 환자 1명)은 외과적 절제와 수술 전후 방사선 치료 및 항암치료를 시행하였다. 수술 사망은 없었 으며,평균3.4년의 추적 관찰 기간동안 3명의 환자가 사망하였다. 전체 환자의 5년 생존율은 82.2$\pm$9%였으며, 임상적 병기에 따른 5년 생존율은 I기와 II기 100%, III기 62.5 %였으며 IV기 에서는 생 존 환자가 없었다 수술시야상에서 비 침습성으로 판단된 II기 흉선종 환자 1명 에서 흥막과 종격동에 흉선종이 재발된 경우가 있었다. 흉선종의 재발로 2명의 환자에서 수술후 14개월과 52개월째에 재수술을 시행 하였다. 흉선종의 예후와 연관이 있는 인자는 Masaoka')분류에 따른 임상적 병기와 흉선종의 완전절제여 투였다. 중증근무력증은 생존율의 위험 인자 \ulcorner아니었다.
