原发性气管癌是一种少见的癌。本院自1963年开院至1989年仅收治4例,均被误诊,有探讨意义的竟在如此少的病例中,有 2例发生重复癌。故予报道,并就原发性气管癌易误性的防范及重复癌现象的研究意义作一讨论。 Primary tracheal cancer is a rare cancer. Since the hospital opened in 1963 to 1989, only 4 cases have been diagnosed and misdiagnosed. Of the cases that have been explored, 2 of these cases have developed repeat cancers. Therefore, a report was made and a discussion was made on the significance of the prevention of erroneousness of primary tracheal cancer and the significance of the duplicated cancer phenomenon.
