重复癌在临床上并非罕见,且有逐年增多的趋势,但常常被误认为转移癌或复发癌而疏于治疗。我们就近几年遇到的六例扼要报导,并略加讨论,希能引起临床医生的重视。 Repeated cancers are clinically not uncommon and tend to increase year by year, but are often mistaken for metastatic or recurrent cancers and are sparsely treated. The six cases that we have encountered in recent years have reported briefly and discussed them briefly. It is hoped that this will attract the attention of clinicians.
