Three hundred and eighty-two patients undergoing thymectomy for myasthenia gravis at 4 London hospitals during the years 1942-64 have been followed to the end of 1967. Five of these patients died from extrathymic tumours while 5·5 would have been expected to do so from the national experience. An additional 5 patients developed non-fatal extrathymic tumours during the period of follow-up. These data provide no evidence that adult thymectomy is followed by an increased risk of neoplastic disease, but more prolonged follow-up will be required before a final conclusion can be drawn.
1942年至1964年间，伦敦4家医院的382例因重症肌无力接受胸腺切除术的患者被随访至1967年底。其中5例患者死于胸腺外肿瘤，而根据全国经验预计应有5.5例。另外5例患者在随访期间发生了非致命性胸腺外肿瘤。这些数据没有提供证据表明成人胸腺切除术后患肿瘤性疾病的风险增加，但在得出最终结论之前还需要更长时间的随访。
