同一病人同时或先后发生两种恶性肿瘤,并可排除复发或转移者,称为双原发恶性肿瘤。习惯简称双癌(Double cancers)或多癌(Multiple Cancers)。1869年Billroth 首先报告了双癌的病例,其后国外又有较多报导,但国内报导较少。随着治疗效果的不断提高,癌症患者生存期日益延长,再次罹患其他恶性肿瘤的问题逐渐引起了人们的注意。现将所见5例报导如下,并结合文献复习略加讨论。 Two malignant tumors occur simultaneously or successively in the same patient, and recurrence or metastasis can be ruled out. This is called double primary malignant tumor. The habit is referred to as Double cancers or Multiple Cancers. In 1869, Billroth first reported cases of double cancer, followed by more reports abroad, but less domestic reports. With the continuous improvement of the therapeutic effect, the survival time of cancer patients is increasingly prolonged, and the problem of once again suffering from other malignant tumors has gradually attracted people’s attention. The following five cases are reported as follows, and a brief discussion of the literature review is given.
