The age-specific frequency of 11 primary pulmonic neoplasms in a closed Beagle colony is presented. The first tumor occurred at 5 years, and the frequency increased progressively in the older age classes. All of the tumors arose from sites distal to the principal bronchi. Although metastases appeared to occur relatively late, with respect to course of tumor development, they were noted in approximately a half of the dogs and most frequently involved the bronchial lymph nodes.
本文呈现了封闭比格犬群体中11种原发性肺肿瘤的年龄特异性发病率。首例肿瘤发生于5岁，发病率在老年组中逐渐升高。所有肿瘤均起源于主支气管远端部位。尽管转移似乎在肿瘤发展过程中相对较晚出现，但约一半的犬出现了转移，且最常累及支气管淋巴结。
